Twenty years later.

The star in front changed three times in the Feitian's observation equipment.

As the distance narrowed from ten to two light years, the size of the star remained almost unchanged, and it was not noticeable to the naked eye as it grew larger.

The spacecraft began to slow down, and after it zoomed in from two light-years away to one light-year away, the star emitting a light yellow halo suddenly became much larger, like a huge basketball, hanging in the starry sky.

After passing through the Oort Nebula and entering the interior of the P654J star system, the star that was originally the size of a basketball suddenly shrank and became as big as an egg.

This strange phenomenon is related to the scattering of light.

In addition, in space, light does not always propagate in a straight line. When it encounters a massive object, such as passing through a star system, the path of the light will be affected by the influence of gravity, causing an arc-shaped bend.

Not to mention massive black holes. It is said that even light cannot escape. The starry sky seen by the naked eye is not necessarily the real starry sky, and there may even be many errors - just like a mirage in the desert.

This is the value of a navigator. An excellent navigator can correct these visual deviations and avoid detours.

The Feitian didn't take any more detours. The navigator, Berekov, did a great job.

Through various observation equipment, Feitian soon made significant gains.

"Rich! Rich! We've discovered a habitable galaxy!"

"Oh my god, God must be taking care of us. We made such a major discovery when we left home for the first time... We will soon cause a sensation in the entire federation!"

Sugaru, who was looking at the high-magnification astronomical telescope, shouted and danced. He looked at the green planet and even murmured: "What a beautiful planet, even more beautiful than my hometown Star Bora!"

"I discovered another large gas planet with a diameter of more than 50,000 kilometers. This is the ninth spherical planet with a diameter of more than 3,000 kilometers in this galaxy!"

Du Xiaopang was also very excited. The gaseous planet is a very good material supply point, and the material reactor is very suitable for replenishing the hydrogen element as nuclear fuel. Moreover, the energy block on the Feitian will be used up sooner or later, and the spacecraft itself cannot be synthesized. The hydrogen element is the best supplement - after all, stars rely on hydrogen to burn.

"This should be the first life planet discovered since the Blue Star Federation left its home planet, right? I didn't expect that our Feitian found it for the Federation. Everyone is so awesome!"

Looking at the increasingly clear video footage coming from the advance detector, Mikoto Mikoto clapped her hands, her face full of pride.

"No, it's not the first one, it should be the second one. The first living planet was discovered more than a hundred years ago by the 'Brave' spaceship and Captain Stannie on Planet Rosa. That galaxy is called ' "Six Treasure Stars', it is said that there are six habitable planets in the habitable zone of this galaxy, among which primitive life evolved in the sea of ​​Planet 3."

The voice of Yun Xinghe next to her made Mikoto Xianglan's originally charming and bright smile turn into one of great loss and regret.

So we are the second one?

More than a hundred years ago?

Xianglan Mikoto turned her head and looked at the ground with a strange expression: "Galaxy-kun, weren't we still asleep more than a hundred years ago? How do you know this?"

"I woke up earlier than you and browsed some news sent by the Federation. While we were dormant, the Federation added more than 100 habitable galaxies."

Yun Xinghe, what he said was half true and half false. There was news about the Six Treasure Galaxy, but Yun Xinghe didn't read much of it. The news about the Six Treasure Galaxy was told to him by the old man in his mind.

So he felt a little regretful that he was not the discoverer of the Liubao Galaxy, but there was no way, unless he could be born a hundred years earlier, or let the Liubao Galaxy run from the mission sector of Star Luosha to the mission sector of Star Bora , it is possible for him to win that glory.

However, this does not mean that the value of the P654J galaxy is lower than that of the Liubao galaxy.

It can even be said that the discovery of P654J caused a great sensation, and even triggered a wave of interstellar exploration within the Federation. Within a period of time, countless detection spacecraft entered space in the hope of finding planets like "Pandora" , and then became famous and rich overnight.

What’s so special about Pandora?

The old man in his mind answered this question.

"According to the information I have, the greatest value of Pandora is the unique plant resources on this planet. These plants show a kind of magical wisdom. They use a kind of flexible vines to build a network. , share knowledge and form collective wisdom.”

"The second greatest value of Pandora is the main reason why this planet was destroyed by the Federation fleet. The so-called death of a few soldiers is just an excuse. The fundamental purpose of the Federation is to exploit this planet for a kind of thing that other planets cannot. There may be special mineral resources that even a supernova explosion may not produce.”

"The scientific name of this element is UNBNUIM, also called 'floating stone'. This element has superconducting properties at room temperature. This is not unusual. There are many room-temperature superconducting materials that humans can synthesize, but floating stone Stone also has a property that it can emit a special force field. Under the influence of this force field, the weight of the object will magically disappear, as if it is weightless."

"How this element is formed is currently unexplainable by science, but it is of great significance to mankind and may even bring about unprecedented technological and energy revolutions."

"To give the simplest example: If the Feitian spacecraft uses about 10,000 kilograms of floating stone, the weight of the spacecraft will be reduced by 70%, the speed can be increased to 0.8C, and the endurance will be increased ten times!"

"In addition, the plants on Pandora that can produce intelligence seem to be related to the floating stone, but the specific principle is unknown. The planet was destroyed before botanists could crack the secret."

The old man in his mind said.

Yun Xinghe opened his mouth and said: "So, Pandora was destroyed by humans' greed for floating stones, rather than the aggressiveness of the intelligent plants themselves?"

"Not necessarily. If these intelligent plants were easy to deal with, all members of the expedition team that found this planet would not have been killed. The commander of the Federation Starfleet could not be completely ignorant and reckless. If it were not for being angry, How could you order the destruction of this planet?"

"In short, the intelligent life on this planet is not easy to deal with. You must be more careful."

The old man in his mind reminded him.

Yun Xinghe nodded and cheered up, not daring to feel any contempt in his heart.

…

A year and a half later.

The Feitian, which narrowly passed through the Corboy material belt, dropped to less than 0.1C.

The planet Pandora is getting closer and closer, less than 20 astronomical units (1 astronomical unit = 150 million kilometers) from Feitian.

At the speed of the Feitian, it can be reached within two days.

However, Feitian did not go straight to Pandora. Instead, it continued to slow down and went to gas planet No. 5, which was 10 astronomical units away.

This gaseous planet was first discovered by Du Xiaopang, so he named it "Xiaopang 1" planet. It has a diameter of 53,000 kilometers, emits orange light, is surrounded by a ring of meteorites, and several There are several small satellites, one of which is 90% made of water. Theoretically, there is the possibility of life on this satellite.

In one day, Feitian reached a close orbit less than 1 million kilometers away from the planet "Little Fatty One".

Then start replenishing supplies.

Water, heavy element ores, elemental hydrogen, all these things are needed.

In less than a day, the water tank is full, the fuel bunker is full, and the ore warehouse is also full.

As for the "Little Fat One" planet, it did not fly over, because there are several giant brown-yellow vortices on the surface of this gaseous planet near the equator. The largest diameter can even stuff Pandora directly into it.

In the Oma Nebula, everyone who had suffered enough did not want to experience such a huge storm again, and did not even think about getting close.

Only one unmanned probe was launched and went to do some detection.

But I didn't expect to make a major discovery.

"There are some living things on this gaseous planet, no, there are many living things!"

Lan Xiulong opened his eyes wide and suddenly pointed at the monitoring screen.

How can this be?

Everyone leaned forward with disbelief on their faces.

It is basic common sense that life cannot exist on a planet with light elements or a planet with a single type of element.

Because there are 20 common amino acids that make up proteins, there are more than dozens of carbon, oxygen, hydrogen, nitrogen, phosphorus, potassium and other elements needed for plant growth. If the essential elements are lacking, it will be like pure distilled water. Just as microorganisms cannot survive, they cannot constitute the rich and colorful world and the diversity of the biosphere.

But this gaseous planet is close to the stratosphere region of the North and South Pole. In the orange atmosphere, there are jellyfish-like creatures floating in the air, flying around like dandelions. The number is difficult to count. In short, they are densely packed, hundreds of billions.

These creatures, under the sunlight, constantly expand and contract their umbrellas and squirm forward, indicating that they are a kind of "animal".

"I guess these creatures should be 'seeds' thrown up from the interior of the planet. Moreover, the gaseous planet is not entirely gaseous. There are also some heavy elements inside. Maybe there is a layer of water under the clouds thousands of kilometers thick. The sea that brews life..."

"In short, this gas planet is of great research value." Sugaru said.

"How about staying here for a few days, catching a few 'jellyfish' and bringing them to the spacecraft for further study?" Weapons Officer Gu Fan suggested.

"It's not necessary. The research value of Pandora is countless times that of this planet. Let's go to Pandora first. When we have enough time, we can go back to this gaseous planet to have a look." Yunxing He said.

"yes!"

Everyone began to get excited.

…

Two days later.

The excruciating slowdown is finally over.

In a space orbit 10,000 kilometers high from the planet below.

The attitude control engine under the wings of the Feitian did not stop working. Instead, it kept emitting high-speed particles, causing the spacecraft to hover statically above the planet. As the planet rotates, every 28 hours, this heavy object with a diameter of about 14,000 kilometers will fly. Every corner of the elemental planet will be clearly observed by the observation equipment on the Feitian and the 100 nanosatellites launched by the Feitian - like a beautiful woman taking off her clothes.

Land accounts for 57%.

Oceans account for 43%.

The poles are covered with icebergs.

The terrain is mainly mountainous, plain, and basin terrain, mostly mountainous, with a small number of lakes, swamps, and volcanic eruptions.

On land, the forest coverage rate exceeds 90%. It is conservatively estimated that there are more than 1 million plant species, more than 100,000 animal species, fish in the water, birds in the sky, large monsters running on the ground... This world is full of vitality.

What is even more exciting is that after the material sampler returned to the spacecraft, Yun Xinghe and the others discovered that this planet, except for its lower gravity constant, is very suitable for human survival.

Such as oxygen content, 25%.

Gravity constant, 0.5G (5 meters per square second).

Types of elements, 268.

A land area of ​​more than 350 million square kilometers is enough for tens of billions of humans to survive on it.

And in the 30 degrees north latitude area of ​​the Eastern Hemisphere, when we saw hundreds of huge floating islands, defying gravity and floating quietly in the air, Yun Xinghe's friends were shocked and dumbfounded. Only Yun Xinghe knew that those Each floating island contains a large number of "floating stones" inside.

Those are priceless treasures.

Everyone will be crazy about it.
