Planet Builder

Xu Tengbin retreated with a group of researchers, and the support troops came to wipe out the rioting bugmen one by one.

A lot of equipment in the institute was damaged. Fortunately, there was no problem with the nuclear fusion reactor, otherwise the city would be bombed to rubble!

The news of Kong Qing's death was sent back to the headquarters, where everyone was silent for a long time.

"Chao Wendao, you can die in the evening!" Song Jinghong broke the silence, he said with emotion: "Kong Lao found the God particle, and his name is enough to leave a deep impression in the history of science!"

"It's admirable, Guo Shi Wushuang!" Lu Mei took a deep breath and sighed.

"This is the torch of human civilization!" He Hongwei suggested, "Elder Kong should get the five-star Xuanwu Medal!"

"Elder Kong really deserves it!" Qin Peng and Cui Weimin nodded their heads. No one has ever won the five-star Xuanwu Medal. Kong Qing is qualified to be the first!

He Xingzhou was also full of emotion in his heart. When he proposed the Xuanwu plan, it was Kong Qing who led people to verify his ideas, and emphasized the point of attaching importance to Zerg genes, which made the Xuanwu plan be implemented.

At that time, He Xingzhou was just an ordinary college student, and his words had no weight. Thanks to the strong support of him and all the academicians, the Chinese civilization has continued to this day.

He Xingzhou sighed deeply: "Kong Lao is the explorer and guide of the advancement of human civilization. We should continue to hold high the torch he passed down!"

"His research, I will continue."

Before Kong Qing, he had already sent a copy of his research materials to He Xingzhou, which contained his thoughts on the standard model of particles and the transformation models of electromagnetic force, strong force, and weak force.

I heard that he still has an important research project with his student Xu Tengbin, which has not yet been completed.

"When peace comes, we will cherish the memory of the heroes." Qin Peng picked up his mood and said, "Insect people appear in the city. They have the means to avoid our detection and disguise themselves as normal people."

"Find out all these worms immediately and destroy them!"

Cui Weimin stood up and said, "I'll arrange it immediately!"

"The Aura king is still evolving in the Atlantic worm nest, and we'd better eliminate it before it evolves into a planetary overlord!" He Hongwei said.

He thought about countermeasures with Qin Peng and other second-level military commanders, and everyone else had their own tasks.

...

He Xingzhou is also thinking of a way, he must make the fastest plan. Once there is a real planetary overlord, how to resist it?

"Without research samples, it is impossible to infer the true strength of the planetary overlord." He Xingzhou pondered, "According to the information obtained before, after the Zerg becomes the planetary overlord, they will have the ability to absolutely crush the planetary behemoth!"

"The Mana Insect King, the Ora Insect King, the Noah Insect King, and Barry's stitched biochemical behemoths are just high-level planetary behemoths, and I have already made all my cards!"

"Without a stronger weapon, I'm afraid it is impossible to defeat it! But time is so tight, what kind of weapon can be made now?" He Xingzhou was also in a dilemma.

There are various high-tech weapons on the technology tree of the quantum optical brain, but humans cannot manufacture them!

Materials, design, manufacturing, etc., are all difficult problems.

He Xingzhou was in distress. All he can do now is to design a more powerful plasma energy storage cannon, or a new combined super-giant mecha.

But he was always worried in his heart, and it didn't help.

For several weeks, He Xingzhou had no clue.

And the team that went to attack the Aura Insect King made no progress at all.

The evolution of the worm king hiding under the deep sea 10,000 meters has evolved. Only small deep-sea mechas and deep-sea battleships can reach such a deep area. After reaching 10,000 meters in the deep sea, they are not planets because of water pressure. The opponents of the giant beasts can only helplessly wait for the evolution of the Aura insect king.

He Xingzhou has not slept for two consecutive days. On his computer drawings is the design of a super-giant mecha, which will be composed of multiple giant mechas and mechanical behemoths.

"The super-giant mecha of the Chaos Demon Ape can release the plasma energy storage cannon by itself. The strength of various weapons has been doubled, and the use is more flexible..."

This super-giant mecha cannot make He Xingzhou relax.

"You should rest for a while, it's been more than two days." Beside him, Xu Zhilan looked at him distressed.

He Xingzhou grabbed his hair and said with a headache: "I can't sleep. I've been restless these days. This is not enough. If the strength of the planetary overlord I predicted is really terrible, all our weapons can't stop it!"

"I believe in you, you can do it!" Xu Zhilan took his hand, "Let's take a break, other designers will continue."

"Well." He Xingzhou put his pillow on her lap and fell asleep slowly in her softness.

Xu Zhilan looked at him quietly, her eyes wandering, she whispered with red lips: "You protect human beings, I will protect you."

He Xingzhou slept all day, and when he woke up, Xu Zhilan was still by his side.

She said, "Xu Tengbin is here. I've been waiting for you for a few hours, saying that I have important information for you."

"Well." He Xingzhou rubbed his eyes. He simply washed and saw Xu Tengbin while eating.

"I'm done!" This was Xu Tengbin's first sentence.

"Teacher's electromagnetic force and strong transformation model!" This was his second sentence, "Director He, the teacher said to give this to you, and you will know how to do it."

"Let me see!" He Xingzhou didn't even eat when he heard the news, so he hurried to see it.

If humans can really master powerful forces, a whole bunch of new technologies will be unlocked!

Xu Tengbin nodded and turned on the holographic projection, which was a complex force conversion device.

"Through this electromagnetic force-strong transformation model, we can convert the electromagnetic force into a strong force to bind microscopic particles!" Xu Tengbin explained while introducing.

"At present, it is only the initial stage, and it can only bind microscopic particles for a short time, and it cannot be maintained for a long time. We will continue to optimize this model."

His voice was haggard with excitement. In order to complete this model, he and a group of fellow apprentices also hadn't slept well for several weeks, and their bodies were already very weak.

He Xingzhou looked at it carefully. If he realized something, he suddenly called out and said excitedly, "I see!"

"Although this model can only maintain a short-term strong force, it can already make weapons!"

"It will be a more powerful weapon than a plasma cannon!"

"I understand!"

"What weapon?" Xu Tengbin asked curiously.

"I only have a preliminary idea now." He Xingzhou said, "I want to conduct a design demonstration, you rest first, wake up and talk later."

He could see that Xu Tengbin, like himself before, also relied on willpower to resist drowsiness, and people might die suddenly in this way!

"Okay." Xu Tengbin really couldn't hold it anymore. When he finished saying this, he fell directly on the sofa, startling He Xingzhou, thinking that something had happened to him, and he was relieved when he found that his breathing was stable.

"This weapon will become our ultimate weapon against planetary overlords!" He Xingzhou looked at the electromagnetic force-power converter and began to work.

He needs to grab time to complete the design and manufacture before the planetary overlord is born!

...

Two months have passed, and it has come to the eleventh year of the implementation of the Xuanwu plan.

This New Year, the people of the land of China have been uneasy, the threat of the Zerg is always there, and the alarm will sound at any time.

The commanders of the Blue Star Alliance, none of them went home for the New Year, they were all busy.

They want to stabilize the interior and clean up the Zerg from all over the world.

Weapons damaged in the previous war are also being repaired and replenished as much as possible to prepare for the planetary overlord.

In the research base in the south, He Xingzhou finally designed this weapon.

"It's it! As long as it is installed on the super giant mecha, there is a chance to kill the planetary overlord!" He Xingzhou said excitedly.

"If it breaks out, I really can't think of any defense to stop it!" Xu Tengbin took a deep breath, "No wonder the teacher said you must have a way!"

"How long will it take to manufacture?" He Xingzhou asked Xuanwu.

Xuanwu replied: "All manufacturing departments have already started manufacturing. Since this is the first powerful weapon made by humans, materials, equipment, and machines all take time, and it is impossible to determine now."

"Okay, it seems that we still have a lot to do." He Xingzhou sat down and continued to study the manufacturing problem.

...

The Atlantic Ocean, the second largest ocean in the world, occupies 20% of the surface area of ​​Blue Star!

The average depth is 3,627 meters, and the deepest Puerto Rico Trench is 9,219 meters deep.

That is the data before the era of cataclysm. After the era of cataclysm, the deepest depth of the Puerto Rico Trench has exceeded 10,000 meters, all because it was excavated by the zerg and built the worm nest.

Beneath the Puerto Rico Trench is the worm's nest of the Aura king.

In the magma, a giant beast is waking up.

It is covered with magma, and the magma of more than 1,000 degrees Celsius is around it, like a hot spring.

"This feeling! Powerful, hungry!" Ola opened her eyes, her green giant eyes in the seabed, extremely frightening.

It opened its mouth like a black hole, and magma poured into its belly.

"Comfortable." Aura worm king poured down countless magma, it slowly protruded out of its body, and all the surrounding zerg lay quietly on the bottom of the sea, expressing surrender.

"Planet Overlord!" Aura Insect King laughed in the sea, "I finally evolved to Planet Overlord. From now on, this planet is my territory and food!"

"Indigenous people, prepare to meet the God of Destruction!"

The sea floor trembled as it moved from the magma, and the magma erupted from the bottom, submerging everything around it!

Next to the Puerto Rico Trench, in the Caribbean Sea.

An air carrier is on a cruise mission, and they have to inspect the situation here at all times to find out the movement of the Zerg.

At this time, the sea began to surge, and the super electromagnetic pulse destroyed all the deep-sea probes on the seabed!

"There is movement!" On the air carrier, Captain Zhou Qian shouted, "Drop the probe and prepare to attack."

"Yes!" On the mothership, the crew members acted.

They drop all kinds of drone detectors and deep-sea detectors, plasma cannons and plasma rays are all ready.

"Aboriginal flying toys?" In the deep sea, the black shadows were getting bigger and bigger.

A planetary overlord floated to the surface, and when he saw its appearance, Zhou Qian's heart twitched violently on the air carrier, and it almost didn't explode.

All the crew members could not help but spread the fear in their hearts!

Just the head of a giant octopus monster is comparable to a planetary beast!

This is just the tip of the iceberg of its body!

It can fly, not by flapping its wings, but by an ability similar to anti-gravity, rising from the bottom of the sea!

When its entire body appeared, the crew of the helicarrier had only one emotion left in their hearts-desperation!

Up to 3000 meters tall!

What is this concept? The altitude of Mount Tai is 1,500 meters, it is twice as high as Mount Tai, and the mountains at its feet are just small mounds!

Even if it is the nine dragons pulling the coffin in the novel, the nine dragons can only be regarded as small earthworms in front of it!

The most powerful battleship in human beings, the sky carrier, in front of it, is just a toy that can be played at will!

Such a body cannot be accommodated by human eyes, and can only be seen from a satellite perspective!

Its every move can cause tsunamis and typhoons!

The Zerg at the planetary dominance level is the beginning of the Zerg moving towards the Planet Devourer. If it is given time, it can eat all the matter on this planet and eventually become the Planet Devourer!

"Launch, weapon, launch, retreat!" Zhou Qian shouted wildly.

Plasma cannon, plasma rays poured on it, and the plasma of hundreds of millions of degrees Celsius was blocked by a layer of plasma when it came in front of it.

It controls energy and forms a protective layer of plasma!

The most powerful weapon of the helicarrier has failed!

"Small natives, what other means do you have?" The Ora Insect King couldn't stop laughing. Its laughter exceeded the limit of human hearing, forming an ultrasonic sonic weapon, which damaged the hull of the air carrier!

"Quickly withdraw!" Zhou Qian knew that they were by no means the opponents of the Planetary Overlord.

"The hull is bound by the magnetic field and cannot escape." The AI ​​system brought them even more desperate news.

Around the Aura insect king, a super-strong magnetic field was generated, which bound the air carrier in place.

"Do you feel hopeless?" Aura Insect King is enjoying this moment, the feeling of being the only one on a planet!

This is the crushing of the lower civilization by the higher civilization, so that they have no power to fight back!

It uses a magnetic field to slowly pull the helicarrier towards itself.

Zhou Qian knew that they were finished.

He sent the last message to the command: "Command, this is the air carrier Fire Feather. We have encountered the Aura king, which has evolved into a planetary overlord. My ship is lost and is about to crash."

Watching them get closer and closer to the behemoth, Zhou Qian said, "Brothers, see you in the next life. Long live the motherland!"

"Long live the motherland!" the crowd shouted.

"Start the self-destruction program!" Zhou Qian gritted his teeth, "Even if you die, you will be skinned!"

"The self-protection program has been started, and the countdown is ten seconds."

"Ten, nine, eight, seven...Three, two, one, start!" The nuclear fusion reactor of the air carrier Fire Feather self-detonated, which was equivalent to a super hydrogen bomb exploding next to the Aura insect king.

The Ora Insect King did not evade in the slightest.

The high temperature and shock wave generated by the explosion briefly broke its plasma defense layer, but the explosion hit its scales without causing any damage!

Even a high temperature of 100 million degrees Celsius cannot break its skin! Even if the super-heavy reconnected electromagnetic gun hits it, it will have no effect!

This is the overlord of the planet, the most terrifying stage of the evolution of the Zerg on the planet! A super monster that can destroy a homeworld civilization!

"Planet Overlord, it has appeared!" The commanders of the Blue Star Alliance Headquarters witnessed this scene.

"The air carrier's attack, self-destruction, has no effect on it at all!" He Hongwei said in horror, "How could this be so, can't the plasma rays penetrate it?"

"Even if 10,000 hydrogen bombs are fired, it will be of no use to it! It can withstand the power of the hydrogen bomb explosion just by relying on its scales!" Song Jinghong's voice changed. Suffocating and desperate!

"How are we going to deal with it?" Lu Mei asked, she couldn't think of a way.

Cui Weimin couldn't think of a way, Qin Peng forcibly suppressed his inner shock and said, "I can only try, let the giant weapon force intercept it!"

Today's Xuanwu base has been built exactly the same as the planetary fortress that He Xingzhou envisioned.

It has a huge underground city, has a high-tech weapon manufacturing factory, has a mech army, an air carrier, a giant mech, a mechanical behemoth, etc.

From the Xuanwu base, combat units can reach the world within two hours!

Aura insect king destroyed an air carrier, and then sent an infrasound message to the world: "Indigenous people, tremble, despair, your god of destruction is coming!"

It flew in the direction of Shenzhou, and the speed was extremely fast, and the air flow it drove rolled up hurricanes and tsunamis!

"The planetary overlord has appeared, go to the Atlantic Ocean and destroy it!" Qin Peng issued an order to the Xuanwu base.

"Yes! Helicarrier fleet, dispatch!"

"Giant mecha troops, dispatch!"

"Mechanical beast army, dispatch!"

"Weapon array, dispatch!"

"Fighter troop, dispatch!"

...

Countless military forces flew to the Atlantic Ocean, and they all knew that the monster they faced this time was an unmatched giant monster!

H-bombs, electromagnetic guns, and other particle weapons are useless to its terrifying existence!

Their weapons, I don't know if they can hurt it, but they know one thing. If they don't intercept it, this planetary beast will destroy China, the Blue Star Alliance, and human civilization in a very short time. All destroyed!

"Insert an urgent news!" This news is being broadcast on all channels on TV programs and on all websites on the Internet.

"The Ora Insect King has evolved into a planetary overlord and is flying towards the land of Shenzhou. We have sent troops to intercept it."

"All residents please prepare to evacuate!"

When the people saw the figure and data of the Aura insect king, they all felt an unmatched despair!

"Three thousand meters high beast! It can level Mount Tai with one foot!"

"Swallowing a hydrogen bomb, hard against plasma rays, how can we deal with it?"

"The end of mankind, the end of the blue star!"

"Even our biggest mecha looks like a toy in front of it!"

"@Planet Builder, what about Academician He?"

...

"My God, is this guy really something that humans can handle?" In a certain company, He Xingzhou's classmate Wang Jiahao and others were stunned when they saw the news footage.

"After so many years, the planetary behemoth still appeared!" Jingcheng University of Science and Technology, the teachers and students were silent after looking at each other. If this behemoth came to Shenzhou, what's the point of hiding in the shelter?

A high-level planetary beast can easily destroy a city, and this planetary overlord, destroying a sanctuary is even easier!

"Is this the end?" In He Xingzhou's house, his parents had already gone to the shelter, although they knew that doing so was of little significance and could only avoid being hurt by small Zerg.

"This is our final test!" Blue Star Alliance Command, all commanders are waiting for the last moment.

They and the Zerg, only one of them can survive.

"How could it be so fast?" He Xingzhou was extremely anxious when he saw the appearance of Aura Insect King.

The weapon to deal with it is not ready to be manufactured!

Its power has exceeded everyone's expectations. He Xingzhou didn't even know that even if he made that weapon himself, would he be able to deal with the planetary overlord?

"Quick, quick, we have to be quicker!" He Xingzhou urged each manufacturing group, he knew that everyone had tried their best to manufacture urgently.

Weapons that can be generated with strong force are never made by humans, they have no experience, and they can't speed up if they want to.

On the ocean, the basaltic troops have already met with the planetary beasts.

More than a hundred spaceships, a hundred giant giants, a hundred mechanical behemoths!

Such a lineup, placed a year ago, could wipe out the Zerg all over the world!

But now, they have encountered a powerful enemy they have never seen before!

"Concentrated attack with plasma rays, its plasma defense layer also has a bearing limit!" In the sky, Xue Yang commanded the fleet to attack together.

"Combination of super-giant mechas, the Great Sage of Pingtian!" The two super-giant mechas were combined and attacked with plasma energy storage cannons.

Mechanical beasts, all on!

In the ocean, in the sky, the mechanical behemoth rushed over desperately.

Countless weapons hit the Aura Insect King, and a blue plasma defense layer appeared around it, blocking most of the attacks.

The plasma energy storage cannon, as well as the concentrated area of ​​the plasma rays, still penetrated the plasma defense layer and hit its scales.

"Is it hurt?" Everyone is looking forward to it, as long as it can be hurt, there is a chance to consume it to death!

To their despair, there were only some scratches on the scales of Aura Insect King, and it was unscathed!

"How could this be?" Xue Yang felt a deep sense of powerlessness. A hundred spaceships could destroy a continent before, but now they can't kill this planetary overlord!

"Our super-giant mecha is useless to him?" The pilots of the super-giant combined mecha, Sun Yi, Deng Jian, Huang Sheng, Xiong Manni, and others were already half-hearted, and it was useless. I'm afraid there will be a one-sided massacre!

"The mechanical behemoth is useless." Lei Yuanfeng sighed inwardly. Although the mechanical behemoth is stronger than the giant mecha in some aspects, facing such a monster, it is only a death sentence.

"Are you finished?" King Aura laughed proudly, "A lower civilization is a lower civilization, do you think I am injured?"

"It's my turn!"

Said, it spit out blue atomic breath, and the diameter of the ray reached 100 meters! It is a hundred times more powerful than the most powerful plasma accumulator cannon in human beings!

The breath of the atom illuminates the entire sky. Wherever it goes, all matter turns into steam. In the sky, dozens of airships are vaporized in an instant before they can escape!

The crew members even screamed and didn't even feel the pain, and they have completely disappeared from this world!

Other planetary beasts need to accumulate energy for a while to release the atomic breath, but it is different, it can release energy almost continuously!

Not only is the atomic breath, but within a few hundred miles around its body, a super-strong electric field is generated!

In the electric field, thunder and lightning appear every moment, and their voltages are as high as hundreds of millions of volts. Those giant mechas and mechanical beasts that tried to get close to it all burst! It was blown into pieces, and the driver inside was also turned into fly ash!

"This is not a war at all, this is death!" He Hongwei shouted.

Qin Peng's hand was firmly on the table. He asked Song Jinghong, "Academician Song, if we use up its energy, will we have a chance?"

Song Jinghong smiled bitterly and said, "If its energy runs out, we will naturally have a chance to hurt it."

"But the problem is, as long as it's on this blue star, its energy won't run out unless it's thrown into a vacuum!"

In the picture, the Aura insect king uses the magnetic field to grab the helicarrier and the giant mecha, one by one.

After eating these, it was not satisfied, and swallowed another belly of sea water.

Song Jinghong said: "Its biological organs allow it to devour all matter on the planet and convert it into energy! Even stones and metals can be fused by it, producing infinite energy!"

"That is to say, unless it is in space, its energy can never be used up!"

When Song Jinghong finished speaking, these commanders, who had seen countless storms, were also shrouded in despair.

This is no longer a matter of trying to find a solution, but with the ability of human civilization, it is no longer able to deal with such a world-destroying beast!

The technological gap between civilizations cannot be filled by their brains here!

"What else can we do?" Cui Weimin asked.

He Xingzhou was not there, and he was still working hard to make that weapon.

"Start the Seed Project." Lu Mei said helplessly.

The Seed Project is the last way to preserve the fire of human civilization, allowing rockets to send part of humans, robots and spacecraft carrying human gene pools into space.

Go to the moon, go to Mars, or some other planet to survive.

Everyone knows that if this plan was in the past, it is still feasible.

But now, they know, there are Zerg on other planets too. These people who were sent to space, I'm afraid they won't survive!

"Do our best to intercept." Qin Peng said, "Even if we fight to the last moment, we must not give up!"

He continued to command operations, using a variety of tactics.

He Hongwei was also in command, Lu Mei and Cui Weimin started the seed plan, and Song Jinghong continued to study the weaknesses of the Aura bug king with the team.

On the sea, the Xuanwu troops used various methods!

Weapon arrays, a hundred hydrogen bomb explosions, plasma accumulator salvos, super-giant mechas, etc., none of the tactics worked.

The super-giant mecha of the Pingtian Great Sage, who killed the Barry Insect King, did not last for 30 seconds in front of the Ora Insect King!

It was torn apart with the claws of the Aura Worm King, and then the mecha and the driver were eaten into the stomach!

"Old Deng!" Huang Sheng saw that the giant mecha that Deng Jian was driving was swallowed by the Aura Worm King. He was so sad and angry that he even wanted to rush over to fight Aura Worm King desperately.

But in the next second, he was blown away by a shock wave and fell into the sea.

"Kill!" The plasma energy storage gun finally made a gap in the defensive plasma layer of the Aura insect king. Feng Xiaolong, the former captain of the sharp blade team, controlled the mechanical mana insect king to rush into the gap, and was about to bite off a piece of the Aura insect king.

The tentacles of the Ora Insect King grabbed this mechanical beast and threw it into the big mouth!

"Attack it's mouth! Throw all the weapons in!" In the sky, Xue Yang commanded the fleet and launched super hydrogen bombs and plasma cannons to attack the mouth of the Aura insect king.

What he didn't expect was that the Aura Insect King did not eat the mechanical behemoth this time, but spit out blue atomic breaths, vaporizing the mechanical beast and the air carrier in the sky.

Xue Yang, the air carrier Dapeng and the entire crew were wiped from this world by it!

"The commander of the air carrier group has died, the new commander Luo An!" Luo An automatically became the new commander of the fleet.

He shouted: "Continue to attack, don't let it get close to Shenzhou!"

He looked at the command screen, and there were less than 30 of the 100 Helicarriers left at the time of departure!

"I may be the most failed commander of the fleet, right?" Luo Xin smiled bitterly. When he was in command of the aircraft carrier fleet, the ship sank.

The first time he commanded the air carrier, the Black Bird crashed, and the second time the air carrier crashed again.

Now, when it was his turn to command the sky carrier group, he encountered a world-destroying beast unmatched by humans!

Aura Insect King is another wave of atomic breath and super electric field sweeping, and the giant weapon force is less than a quarter of it.

Lei Yuanfeng reluctantly reported to the headquarters: "Headquarters, we have been unable to stop the Aura King, it continues to advance towards Shenzhou!"

"We will continue to delay!"

The weapons are still on the offensive, but it is only a matter of time before the entire army is wiped out.

...

At the research base in the south, a proton stripper is being built.

It is a tool to convert the electromagnetic force into the strong interaction force to strip the protons out of the nucleus, and it is also the effort of Kong Qing's research.

He Xingzhou will use this device to strip out the protons in the nucleus!

The nucleus of matter consists of positively charged protons and uncharged neutrons, each of which is about 2,000 times the mass of an electron.

For most elements their overall mass is roughly the same, so nearly half the mass of all matter is protons.

Under normal circumstances, the positive charge carried by protons and the negative charge carried by electrons in the nucleus of a substance will form a stable balance.

And if any party is stripped out, this balance will be quickly broken!

A gram of protons, without electrons to make their net charge zero, would create an electric field strong enough to strip electrons from their host atoms and ionize air up to 15 kilometers away.

Such a huge and strong magnetic field can send lightning through granite at a range of 10 kilometers!

Given a sufficient number of protons stripped of electrons, it can destroy almost any material!

What He Xingzhou wants to create is a super weapon that uses strong interaction to forcibly "bundle" protons of a certain mass together.

He named it, Proton Missile! This is also the last weapon He Xingzhou is going to use against the planetary overlord!

Thanks to NRS11, Wuxiang Broad Bean, Lancer Ali and other book friends for their rewards.
