Controlled nuclear fusion, which requires extremely high temperatures and pressures.

Although the temperature of hundreds of millions of yuan will not cause much harm to Yuan Yingqi, it is very dangerous to other disciples.

Especially if the experiment goes wrong and the controlled nuclear fusion becomes uncontrollable, it will become a hydrogen bomb, which can easily raze the entire Qianqing Mountains to the ground.

So Tang Yan and Yun Yi left Qianqing Mountain, found an uninhabited desert for experiments, and announced a retreat.

For high temperature and high pressure, the alchemy master Yun Yi had the most say and gave Tang Yan a lot of help.

In a flash of 30 years, time flies.

As early as 10 years ago, Tang Yan was able to make controlled nuclear fusion stable output energy.

However, due to its huge size, it can only be used as a power plant if it wants to be used in the modern world.

5 years, with the efforts of Tang Yan and Yunyi.

Controlled nuclear fusion can already be controlled in a space of half a cubic meter, the application is more comprehensive, and the safety is still guaranteed.

In the remaining 5 years, Tang Yan and Yunyi began to do research with helium-3.

Of course, this helium-3 was not obtained by normal means, but a magic weapon refined by Yun Yi, which could fly into the sky, intercept a piece of solar wind, and refine it from it.

In fact, if you can use cultivation methods, controlled nuclear fusion will be much simpler.

But the problem is that if you can cultivate, you can just use aura as energy, how can it be so strenuous.

In the past 30 years, Tang Yanguang has stopped Yunyi and prevented him from using the cultivation method in the process, which has taken at least three years.

The hardships are not enough for outsiders.

On this day, Tang Yan ran out of helium-3 at hand, and he was a little annoyed with the closure, so he took out the small magic weapon that collected the solar wind, and prepared to go out to collect the solar wind, and by the way, he was a little annoyed.

Seeing that Tang Yan was leaving, Yun Yi immediately stood up, moving quickly, how could he still have the slightest appearance of being light and breezy.

He tugged on Tang Yan's sleeve: "Last time, it was the solar wind you went out to collect, this time it should be my turn, right?" ”

It seems that Yunyi also wants to go out for a walk.

After all, simple things that can be easily done with aura are controlled by Tang Yan and cannot be used at all. After a long time, my mentality is as stable as Yunyi, and I can't help but feel a little depressed.

Every now and then it is necessary to stay away from nuclear reactors that seem meaningless to him.

But for the sake of safety, the nuclear reactor must have someone watching.

Tang Yan and Yun Yi can only have one person go out for a walk.

"No! You went out last time and last time, and this time it should still be me! Tang Yan didn't let Yunyi at all.

Her mentality is not as good as Yunyi's, she does one thing day and day for a long time, and if she doesn't rest, people are easy to get irritable.

The two argued like children for a long time, and in the end, no one let anyone.

Tang Yan called Xiang Qingqing and asked her to come over and collect it with a small magic weapon to collect the sun wind.

It can be seen from the candidates selected that Tang Yan's love for cult CP is not dead.

It's that Yunyi and Xiang Qingqing don't call each other.

Tang Yan has knocked so many cps, except for Tian Zixin and Qi Shumo, who were originally cps in the last world, and they have never succeeded.

Yun Yi, who was both defeated with Tang Yan, returned to the laboratory sadly, looked at the broken copper and iron in front of him, which seemed meaningless to him, and sighed helplessly.

"Didn't you say you wanted to cultivate my interest? When the hell is this a head! ”

"It's coming, it's coming!" Tang Yan smiled and comforted, and suddenly his face changed, and his eyes showed surprise.

"Yunyi! My mission accomplished! ”

Yunyi didn't react: "The new round of experiments hasn't even been completed halfway." ”

Tang Yan patted Yunyi's shoulder excitedly.

"I'm talking about the task of selling mobile phones! Sister is going to fulfill her promise to take you to fly! ”

She said to the system in her heart: "Help me contact Weiwei, I won't go back directly now, I need her to show up and help." ”

Weiwei, who was sleeping in space, received the news of the successful completion of the manifestation in front of a small world, opened her eyes and stretched lazily.

Then she saw that a few thousand meters away from her, there was a strange small magic weapon that was constantly absorbing the solar wind.

This thing had passed by her many times, and Wei Wei had already noticed it, but she didn't bother to open her eyes because it was not lethal at all.

But when he opened his eyes, he found that there was Tang Yan's breath on this strange-shaped thing.

"This ugly thing is Tang Yan's?"

Wei Wei scratched her head, gently stretched out her palm, and there was an invisible force to firmly grasp the small magic weapon that was working.

The defense on the little magic weapon activated, and he struggled violently.

After struggling for only two seconds, he stopped, and never moved again, and it turned out to be broken.

Vivi hurriedly withdrew her hand.

"It's this ugly thing that has a defensive self-destruct device, it has nothing to do with me!"

She can actually use the method of time regression to repair the small magic weapon, but this thing is weird and ugly, Wei Wei didn't bother to bother, waved her hand, and directly let the small magic weapon turn into dust and float in space.

Wei Wei straightened the clothes on her body, adjusted the expression on her face, stretched out her legs and came to Tang Yan's side in one step as if she was fine.

"Tang Yan, do you miss me?"

She opened her arms with a smile, ready to give Tang Yan a loving hug, and then the look on her face froze.

She turned her head and looked at the nuclear reactor beside Tang Yan, and was stunned.

Isn't this a product of interstellar technology?

How did she remember that this time she came to a small world of cultivation?

Wei Wei was a little stunned, but when she saw Yun Yi beside Tang Yan, she breathed a sigh of relief.

Sure enough, Tang Yan and her carefully selected Buddhist male protagonist will definitely be affected by some good influences.

Tang Yan looked at Wei Wei, whose face was constantly changing with her arms outstretched, and squatted down with a smile and hugged her back along the other party's outstretched arms.

"I miss you too."

Wei Wei knew that Tang Yan was a "patient", so she didn't dare to ask Tang Yan directly, but asked what happened to the main god system during this time.

The main god system betrayed Tang Yan in an instant, and told Wei Wei about Tang Yan's experience in this small world.

After Weiwei listened, her mouth opened wide.

Tang Yan didn't learn from Yun Yi that Yun Yi was light and light, and he learned almost everything.

Not to mention the cultivation of the alchemy refiner, there is some incongruity between neuronal connection and controllable nuclear fusion appearing here, right?

One person has to be busy with so many things, so he can do things!

It's going to get worse, right?

Wei Wei was very worried, but she had no choice, and she was reluctant to blame Tang Yan, the patient, so she had to glare at Yun Yi hatefully.

has lived for tens of millions of years, not only did he not bring Tang Yan lightly, but he was also influenced by the other party more and more uncalmly.

Bah! Litter!

Wei Wei instantly had a bad impression of Yunyi, she took Tang Yan's hand and said unhappily.

"I don't want to take this one named Yunyi with me."
