Cataclysmic Era: I can unlock the tech tree

The next morning, just as dawn was breaking, Lü Yongchang got up and left the dormitory.

This was a habit he developed in his previous life.

On a September morning, there was a slight chill in the air.

Looking at the deserted main road of the university, Lü Yongchang couldn't help but fall into deep thought.

Where should he go?

Perhaps it was a habit left over from his previous life, but Lü Yongchang always felt empty inside when he didn't have any research tasks to do.

I wonder how my proposed controlled nuclear fusion plan is doing in the review process...

I hope nothing bad will happen.

Although he was very confident in the plan, he was not so confident in his current position.

Right now, he is just an ordinary sophomore at Sandaokou University.

Looking back now, he himself feels that he acted somewhat recklessly.

But thinking that he only had twenty short years, Lü Yongchang felt somewhat helpless.

He has no time to waste!

There are 80 billion people living on Earth!

Sending all 80 billion people into space and to the next habitable planet... the technological level required is absolutely staggering!

In his original plan, out of 8 billion people, it would be extremely lucky if only 10 million could escape!

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

Perhaps... as long as we advance our technology fast enough, all of humanity can escape Earth alive!

If Level 1 civilization isn't enough, then let's go with Level 2!

If that still doesn't work... he refuses to believe that even a level three civilization can't do this!

While thinking about his plans for the next twenty years, Lü Yongchang wandered aimlessly around the campus.

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

A building that is entirely white.

This is... the library of Sandaokou University!

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

Upon entering the library, Lü Yongchang subconsciously followed his muscle memory and found the seat he had liked to sit in most in his previous life.

No one is reserving seats!

A hint of joy appeared in his eyes.

But what should I watch...?

Lü Yongchang's eyes flickered slightly.

He remembered the information provided by the technology tree system.

[Prerequisite: Understanding the sonoluminescence phenomenon]

Looks like I need to find some books about sonoluminescence!

……

Time always flies when you're reading.

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

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

Peacock mantis shrimp!

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

When attacking prey, the peacock mantis shrimp can launch the front end of its raptor in one-fiftieth of a second, reaching a top speed of over 80 kilometers per hour, with acceleration comparable to a bullet!

During this process, sonoluminescence can be produced!

Sonoluminescence has also been studied by numerous researchers.

The principle is very simple: when a mechanical wave acts on a liquid, a phenomenon called "mechanical wave cavitation" is generated in the liquid.

In other words, bubbles are generated in the liquid, and the bubbles then collapse into a very small volume!

During the collapse, the bubble generates extremely high temperatures, which causes it to emit a flash of light at that moment!

Lü Yongchang astutely grasped a key element.

Extremely high temperatures can be generated inside the bubble!

It seems... the breakthrough in fusion reactor miniaturization technology will begin with this tiny bubble!

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

"Excuse me, is there anyone sitting here?"

Just as Lü Yongchang was engrossed in reviewing various academic papers, a slightly cool female voice reached his ears from the side.

That voice... why does it sound so familiar?

He suddenly raised his head and looked around!

The moment he saw the person who had arrived, Lü Yongchang's heart skipped a beat!

is her!

Clearly, Lü Yongchang's overly aggressive actions had frightened the girl in front of him.

She took a step back, somewhat frightened, and apologized repeatedly, "I'm so sorry, I'm so sorry, if someone were here, could I..."

"There's no one here, please have a seat!"

Lu Yongchang interrupted the girl directly, then forced a stiff smile onto his face: "I, I was a little startled just now, and my reaction was a bit over the top, I'm sorry."

The girl smiled and waved her hand, saying repeatedly, "It's nothing, it's nothing. I was too abrupt in asking!"

As she spoke, the girl sat down in the seat next to Lü Yongchang without any hesitation.

Looking at the girl's profile, a look of disbelief appeared in Lü Yongchang's eyes.

It felt like I had returned to my previous life.

At that time, Su Yutong was also like that, quietly sitting in the chair next to him, helping him with various scientific research tasks.

Seemingly noticing Lü Yongchang's gaze, the girl looked up at him.

"Hello...?"

The girl looked at Lü Yongchang with a puzzled expression and said softly, "Is there something you need?"

He snapped back to his senses, bit his tongue hard, and used the intense pain to pull himself out of the fragments of memory.

"It's nothing, it's nothing, you just look a little familiar..."

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

The girl looked at Lü Yongchang's profile with a strange expression and subconsciously moved her body to the side.

I have a feeling... there's something strange about this person's gaze.

She somewhat regretted sitting in that seat.

As for Lü Yongchang, he was naturally unaware of the girl's ulterior motives; at this moment, he was already captivated by a research paper.

On the Relationship between Sonoluminescence and Cold Fusion

Upon seeing this thesis title, Lü Yongchang's breath caught in his throat!

Could it be that... someone has already figured out how to miniaturize fusion reactors?

impossible!

In the previous life, even controlled nuclear fusion was not successfully developed until 2040, let alone the miniaturization technology of fusion reactors!

In other words, under normal development, it will take another ten years for truly controllable nuclear fusion technology to emerge!

Lü Yongchang quickly flipped through the documents in his hands.

After a long while, he exhaled a soft breath, a hint of relief flashing in his eyes.

It's he who thinks too much.

This paper is just a guess; it doesn't involve any in-depth research.

It's fair to say it was essentially a rejected draft.

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

He glanced at the authors of the paper.

Tao Yuda.

If you have the chance, you can go and talk to him.

Although academic papers aren't very useful, this research intuition is quite accurate.

If he is truly a promising talent, Lü Yongchang would not mind including him in his future R&D team!

"Click-clack-click-clack..."

Just as Lü Yongchang was pondering over there, he heard the sound of a ballpoint pen ratcheting.
