Early the next morning, just after dawn, Lu Yongchang got up and left the dormitory.

This is a habit he developed in his previous life.

In the early morning of September, there was a little coolness in the wind.

Looking at the empty main road of the university, Lu Yongchang couldn't help but fell into deep thought.

This... where should he go?

Perhaps it is a habit left over from his previous life, Lu Yongchang, who has no research tasks in hand, always feels empty in his heart.

I don't know how the review of the controllable nuclear fusion plan I proposed is going well...

It should be... nothing will happen, right?

Although he was very confident in the plan, he didn't have much confidence in his identity at this time.

Now he is just an ordinary sophomore at Sandaokou University.

Thinking about it now, he himself felt that this was a bit reckless.

But thinking that he only had twenty years, Lu Yongchang felt a little helpless.

He has no time to waste!

There are 8 billion human beings living on the earth!

If you want to send all 8 billion humans into space and go to the next habitable planet... the level of technology required is extremely exaggerated!

Originally, in his plan, out of 8 billion human beings, only 10 million human beings are needed to escape, which is considered extremely lucky!

But since he learned of the existence of the technology tree system, his mind suddenly became active.

Maybe... as long as you can climb the technology tree fast enough, all human beings can escape the earth alive!

If the first-level civilization is not good, then the second-level civilization!

If it doesn't work...he doesn't believe it, even a third-level civilization can't do it!

Lu Yongchang wandered aimlessly around the campus while thinking about the plan for the next twenty years in his mind.

Suddenly, out of the corner of his eye, he saw a familiar building.

The genuine version of this novel can be found on another site. Support the author by reading it there.

A whole white building.

This is...the library of Sandaokou University!

Lu Yongchang's eyes moved slightly, he turned and walked towards the library.

Entering the library, Lu Yongchang subconsciously followed his muscle memory to find his favorite seat in his previous life.

No one is occupying a seat!

There was a look of joy in his eyes.

But what to look at...

Lu Yongchang's eyes moved slightly.

He thought of the information prompted by the technology tree system.

[Precondition: Analyzing the phenomenon of sonoluminescence]

Time to find some books on the phenomenon of sonoluminescence, it seems!

...

Reading time always flies by so fast.

In the blink of an eye, more than two hours passed quickly.

Lu Yongchang closed the book in front of him, thoughtfully wrote down a few key points on the A4 paper in front of him.

Peacock Mantis Shrimp!

The so-called sonoluminescence phenomenon was first discovered in nature in a creature called the peacock mantis shrimp.

When the peacock mantis shrimp attacks its prey, it can eject the front end of its trapping limb within one-fiftieth of a second, with a top speed of more than 80 kilometers per hour, and the acceleration is comparable to that of a bullet!

In this process, the phenomenon of sonoluminescence can be produced!

The phenomenon of sonoluminescence has also been studied by numerous researchers.

The principle is very simple. When the mechanical wave acts on the liquid, a "mechanical wave cavitation" phenomenon will occur in the liquid.

That is, bubbles are created in the liquid, which then collapse to a very small volume!

During the collapse process, extremely high temperature will be generated inside the bubble, and at this moment, an instant flash will be emitted!

Lu Yongchang keenly grasped a key element.

Extremely high temperatures can be generated inside the bubbles!

It seems... the fusion reactor miniaturization technology is about to break through from this small bubble!

After all, the initiation of nuclear fusion requires a high temperature of hundreds of millions of degrees Celsius as a prerequisite!

"Hello classmate, may I ask, is there anyone sitting here?"

Just as Lu Yongchang was immersed in looking up various papers and materials, a slightly cold female voice came into his ears from the side.

This voice...why does it feel familiar?

He suddenly raised his head and looked around!

The moment he saw the person coming, Lu Yongchang's heart twitched violently!

is her!

Obviously, Lu Yongchang's aggressive actions scared the girls in front of him a little.

She took a step back in fear, and apologized repeatedly: "I'm sorry, I'm sorry, if there is someone, I can..."

"No one, sit down!"

Lu Yongchang directly interrupted the girl's words, and then he forced a stiff smile on his face: "I, I was a little scared just now, and my reaction was a little big, I'm sorry."

The girl waved her hand with a smile, and said repeatedly: "It's okay, it's okay, it's because I asked too abruptly!"

With that said, the girl directly and generously sat on the seat next to Lu Yongchang.

Looking at the girl's side face, Lu Yongchang's eyes showed a bit of trance.

It seems to have returned to the previous life.

Su Yutong was the same at that time, sitting quietly on the chair beside him to help him with various scientific research tasks.

As if sensing Lu Yongchang's gaze, the girl raised her head and looked at him.

"You... how are you?"

The girl looked at Lu Yongchang suspiciously, and said softly, "What's the matter?"

He came back to his senses suddenly, bit the tip of his tongue hard, and pulled himself out of the memory fragments with the help of severe pain.

"It's okay, I just think you look familiar..."

As he spoke, Lu Yongchang forced himself to turn his head and focus on the paper in front of him.

The girl looked at Lu Yongchang's side face with a strange face, and subconsciously moved to the side.

I always feel... This person's eyes are a little weird.

She somewhat regretted sitting in this position.

As for Lu Yongchang, naturally he doesn't know the girl in the girl's heart. At this time, he has already been attracted by a paper.

"On the relationship between sonoluminescence and cold nuclear fusion"

The moment Lu Yongchang saw the topic of this thesis, his breath suddenly suffocated!

Is it possible... Someone has already researched the miniaturization technology of the fusion reactor?

impossible!

In the last life, even the controllable nuclear fusion was successfully developed in 2040, let alone the miniaturization technology of the fusion reactor!

In other words, the real controllable nuclear fusion technology will take ten years to appear according to normal development!

Lu Yongchang quickly flipped through the documents in his hand.

After a long time, he let out a breath of turbid air, and a little relief flashed in his eyes.

He was thinking too much.

This paper is just a guess, basically without any in-depth research.

It can be said that it is equivalent to a waste manuscript.

No wonder...he had never seen this paper in his previous life!

He glanced at the author of the paper.

Tao Yuda.

If you have a chance, talk to him.

Although the paper is not very useful, this research intuition is quite accurate.

If it is really a malleable talent, Lu Yongchang would not mind including him in his future R&D team!

"Click, click, click..."

Just as Lu Yongchang was thinking over there, there was a sound of ratchet movement of the ballpoint pen.
