BTTH: Emperor Yan, please exercise restraint, you are really a simple brother.

If the four elders of the Snake Tribe knew what Medusa was thinking, they would definitely reply: "He really gave too much, and they couldn't refuse.

Not to mention anything else, the Heavenly Soul Blood Bone Pill alone is enough to drive them crazy.

According to the secret method within the Snake Tribe, newborns of the Medusa lineage will be nourished by the secret method after birth, and are divided into three levels: upper, middle and lower, representing three potentials.

The inferior secret method only requires some ordinary powerful elixirs. If the Medusa baby nourished by this method does not have a great opportunity, it will stop at the level of fighting emperor for life, and it will not work if it wants to take the path of strange fire stimulation and breakthrough. The death rate reaches 99%.

The medium secret method requires a sixth-grade elixir called "Snake Marrow Sloughing Pill" as the main medicine. The newborn Medusa nourished by this method can have the potential to reach the Douzong level. For example, Zhang Yuan is now standing The Queen Medusa in front of me.

If she hadn't wanted to make a breakthrough after her bloodline advanced and have higher potential and combat power, she would have already broken through to the Douzong level.

The superior secret method requires an extremely difficult to refine "Tianhun Blood and Bone Pill" elixir, a seventh-grade elixir with heavenly power that can maximize the stimulation of the newborns of Medusa's lineage. With potential, he can easily grow into a Dou Zong in the future. With the appearance of a Dou Zong, he will succeed without any lack of opportunity, which is terrifying.

In all these years, Medusa has never given birth to a newborn child who has been nourished by the Heavenly Soul Blood and Bone Pill.

But now, Zhang Yuan has clearly stated the price, and as long as the Snake Tribe works for him, he can have it.

Not to mention the benefits such as the alien fire stimulating bloodline evolution.

"Master Palace Master, do you have the ready-made Heavenly Soul Blood and Bone Pill in your hand?" The smiles of the four Snake Tribe elders became flattering, making Medusa's mouth twitch slightly.

"I don't have the Heavenly Soul Blood Bone Pill. After all, I don't have the recipe. This is a secret that you snake people don't tell." Zhang Yuan shook his head.

The smiles of the four elders froze, but the next moment they saw Zhang Yuan take out a box, opened it and said: "But I have a Yin Yang Life Soul Pill here, which is a seventh-grade intermediate pill. I believe the four of you can identify its Cheng Dan. Time?"

The Yin and Yang Life and Soul Pill has similar effects to the Bone and Blood Fusion Pill. It is a weakened version of the eighth-grade pill, the Bone and Blood Fusion Pill. Xiao Yanzi used it when refining the body of Lord Tianhuo.

Some time ago, Zhang Yuan just gathered together the elixir needed to refine this elixir, so Zhang Yuan asked Yao Chen to refine it in the Taixu Realm. It took nearly ten days to finally successfully refine it in case of emergency.

Of course, Zhang Yuan didn't care about the elixir. Instead, what he valued was the elixir that the seventh-grade elixir experienced when it was formed. All of them were devoured and sealed by Xuanhuang Yan and turned into nutrients for the growth of the Six Dragons' Thunder Gang Fire, helping him to cultivate. Rapid growth.

"What a rich thunder attribute energy!"

The four elders and Medusa were all looking at the elixir and found that it was about the size of a dragon's eye. It was black and red in color, with a round surface and extremely glossy appearance. You could feel the coldness and warmth from a distance.

There is still a certain amount of thunder energy remaining around this elixir, indicating that it was refined not long ago.

This just shows that there is someone around Zhang Yuan who can refine seventh-grade intermediate elixirs.

Then there is no problem in refining the Heavenly Soul Blood Bone Pill.

"Okay! Okay! Okay!"

The four elders felt joy in their hearts.

As long as the snake people can get a Heavenly Soul Blood Bone Pill in the future, they will have a bright future.

"For more information, the four of you can find out on your own. I'm here to see Medusa and I have other matters." Zhang Yuan was not interested in acting as a commentator.

"Do you have a problem with me?" Medusa clasped her chest with both hands, pretending to be cold and arrogant: "You haven't helped me break through yet, and you want me to do something for you again?"

When he agreed to give Qinglian Earth Heart Fire, Zhang Yuan helped her break through.

As a result, before giving Qinglian Earth Heart Fire, she was asked to first remove the seal from Haibodong.

Not only that, Zhang Yuan did not benefit Qinglian's exploration under the Earth's Heart Fire.

Do you really treat her as a tool?

"Will you help?" Zhang Yuan asked.

"Calculate the mission." Medusa took out the Nine Abyss Token, threw it away, and said, "The source point and the mission point."

She could do things, but she didn't want her efforts to go to waste again.

"Are you sure you want to count?" Zhang Yuan had a smile in his eyes.

"Of course." Medusa nodded.

"Okay." Zhang Yuan showed a helpless expression and said, "Before you start to advance, I would like to give you an opportunity to observe up close the sixth-level monsters breaking through to the seventh level."

"Looking at it now, I'll sell it to you with a clear price tag."

Medusa's smile froze slightly, and she pressed her silver teeth and said, "You are so generous, Lord Palace Master!"

Zhang Yuan laughed, waved his hand and said: "Let's go, it's about to start."

Feeling the power of space teleportation, Medusa did not refuse.

The next moment, both of them appeared in Taixu Realm.

On the Gravity Peak, all the dragon energy was transformed into a dragon shape under the control of Zhang Yuan, hovering around, leaving a central area empty.

In the center area, black clouds are densely covered, with purple and blue lightning intertwined, brewing terrifying energy, with a pressure that can destroy the world.

Around Gravity Peak, the monsters headed by the Amethyst Winged Lion King were lying on the ground watching, and people from the Xiao family were also watching quietly outside.

"Is that the Jiama Empire's Nether Sea Dragon Beast?"

Medusa's purple eyes flashed, and she immediately noticed a huge beast with a single horn and a body of more than ten feet directly under the thunder cloud.

She had fought against him before, or rather beaten him one-sidedly, so she could recognize him.

"That's right, but he will soon become a Youhai dragon!" Zhang Yuan said.

"Sea Dragon?" Medusa opened her mouth slightly and said, "It wants to evolve its bloodline just like me?"

When a monster breaks through from the sixth level to the seventh level, it does not need to undergo the test of thunder.

Those who will encounter thunder tribulation are bloodline evolution, which is similar to the treasures of heaven and earth that have been nurtured for many years and are born, just like elixirs that take over the creation of heaven and earth. It has the meaning of changing fate against nature, so it has to withstand the test.

There is also the fact that many Warcraft will choose to transform when they break through to the seventh level. In this process, they need to withstand the lightning tribulation of transformation and reshape their bodies.

Medusa knew that the bloodline of the Gama Empire royal family's Nether Sea Dragon Beast was not bad, and was even stronger than her Purple Nether Flame Snake, but its evolution was more difficult.

In addition, the Nether Sea Dragon Beast fought for the Jia Ma Empire for many years and suffered many injuries, making it almost impossible to advance and evolve.

"That's right." Zhang Yuan nodded and said: "The Gama royal family consumes source points and mission points in exchange for the opportunity to bathe in the seventh-level dragon energy for the Nether Sea dragon beast, so as to make up for the hidden damage and lost potential, and complete the evolution."

"With the strength of the Nether Sea Dragon Beast, once it successfully evolves its bloodline, it should be able to make a breakthrough."

"Whether it is the process of evolution or the process of advancing from the sixth level to the seventh level, you can observe it."

Medusa nodded slightly, her eyes becoming extremely serious.

Several hours later, the power in the thunder cloud finally accumulated to a certain extent, and turned into a thick thunder and fell.

This is not only a test, but also a tempering process. Although Zhang Yuan can interrupt and stop it, he will not do it.

"This Nether Sea Dragon has good luck. The Dragon Qi of the Taixu Mirage Dragon contains a trace of the blood of the Taixu Ancient Dragon. If it completes its breakthrough, it may be able to join the Taixu Ancient Dragon clan in the future and have higher achievements." Yao Lao told Xiao Yan. said.

Xiao Yan's eyes were bright and he wrote down everything Yao Lao said.

He did not forget Zhang Yuan's advice to read more books and learn more about the common sense of the mainland.

"boom!"

Countless thunderbolts fell, and the Nether Sea Dragon Beast was riddled with holes and its whole body was damaged, but a special aura began to appear in its blood.

Faced with a steady stream of thunder, he felt that he might not be able to sustain it.

But before he could get discouraged, the dragon energy condensed around him came over to repair his body and increase the power of his bloodline.

"Boom! Boom!"

Another half an hour later.

The extremely powerful thunder almost destroyed the body of the Nether Sea Dragon Beast, but the bloodline power in its blood became increasingly rich.

The clouds finally began to dissipate, and the Nether Sea Dragon Beast took out a few fifth-grade elixirs and drank them to repair his fighting spirit while stimulating the power of his bloodline to transform his body.

At the same time, he will use the insights from the thunder tribulation to understand the power of space and begin to complete the advancement.

As long as the advancement is successful, all its injuries will be healed.

"It is estimated that it will take seven to fifteen days to completely complete the advancement. Even if you fail, your cultivation level will not go back."

Zhang Yuan withdrew his soul power and asked Medusa: "Are you going to observe and learn for a few days, or will you start evolving directly and then advance?"

"Start evolving directly!" Medusa licked her red lips and made a quick decision.

She didn't think she couldn't do anything that even the Nether Sea dragon beasts could do.

She also doesn’t want to be surpassed by the Nether Sea Dragon Beast!

"Okay, let's get started."

Zhang Yuan completely respected Medusa's opinion and summoned Xuanhuang Flame to wrap Medusa's body.

The space shifted, and Medusa entered the Xuanhuangyan space and found that the power of thunder was raging in it, but she was being swallowed by the six dragons' thunder fire.

"You enter samadhi, be prepared and tell me, I will use the Six Dragon Thunder Gang Fire to help you."

The Nether Sea Dragon Beast can actually evolve through the Six Dragon Thunder Gang Fire, but it is not necessary.

Because the Nether Sea Dragon Beast is a sixth-level water attribute monster, it does not like strange fire and is also afraid of the power of thunder.

Being tempered by such flames is a kind of torture for the Nether Sea Dragon Beast, but the effect is not better than directly swallowing the Dragon Qi of the Taixu Mirage Dragon.

Medusa is a snake, her body is tempered by thunder, and her blood is stimulated by flames, which is a special secret method.

"I see."

Medusa fell to the ground, returned the Magic Moon Pearl to Zhang Yuan, revealed her true form and sat down with her snake tail crossed.

She began to adjust her breath and sort out her previous observations and experiences.

An hour later, she said: "Let's start!"

Zhang Yuan left the Xuanhuangyan space with a thought, and then controlled the six dragons' thunder fire to fall.

Medusa transformed into the purple flame snake and rushed towards the Six Dragons Thunder Gang Fire with madness in her eyes.

"boom!"

Amidst the silver flames and thunder, the purple snake's body began to collapse.

Everything in the space has no secrets to Zhang Yuan. He can clearly find that the snake scales on the purple snake's body began to twist rapidly after entering the strange fire, turning black in the blink of an eye and falling down.

Red blood flowed out from everywhere on the purple body, but it was only instantly burned into nothingness by thunder and strange fire, with countless dazzling bloody traces.

As the blood flowed away rapidly, the body of the purple snake began to shrink at a speed visible to the naked eye, and the purple eyes also showed unbearable pain, paranoia and madness.

Severe pain hit, making Medusa want to scream.

Right now it was just pain in her body, but she felt that her soul was also trembling.

But when the pain was about to increase again, a force spread within her body, repairing her injuries, and weakening her pain like fire and ice.

"ah!"

Medusa still screamed, but it was not sharp, just a way of venting.

This process lasted for three hours. The purple snake's body covered with beautiful purple scales was completely blackened. It was originally more than ten feet long, but now only two or three feet were left.

Without the supplement of dragon energy, it is difficult to imagine how much pain this process of alien fire transforming bones and blood would bring to Medusa's body.

Zhang Yuan frowned as he sensed the unique blood fluctuations in his soul power.

"What happened? Evolution failed?"

"No, this is actually a new soul!"
