I accidentally got a two-way foil in my second level civilization

"Lü Yongchang! What are you up to!"

Seeing Lü Yongchang stand up and walk towards the podium, Professor Guan Hualiang's expression changed slightly, and he immediately snapped at him!

"This is a classroom. Get a hold of yourself!"

Professor Guan Hualiang's scolding fell into Lü Yongchang's ears, giving him a sense of inexplicable familiarity.

He hadn't heard such scolding for more than ten years!

A faint smile appeared on Lü Yongchang's face. He nodded slightly at Guan Hualiang. "Professor Guan, I'm sorry, but I need to borrow the blackboard."

Guan Hualiang was both shocked and angry!

After teaching for so many years, this was the first time a student had "asked to borrow" his blackboard during class!

The next moment, he saw Lü Yongchang walk up to him on his own, pick up a white - board marker from the podium.

Guan Hualiang was so angry that he almost laughed!

This wasn't borrowing at all!

He hadn't even nodded in agreement!

This was clearly snatching!!

"Student Lü, this is my last warning to you..."

Guan Hualiang took a deep breath, suppressing his anger, and said softly, "Go back to your seat now, and I can deal with your previous actions leniently. If..."

Lü Yongchang straightened his back and looked at Guan Hualiang with deep eyes.

Guan Hualiang's pupils constricted slightly, and the words that were halfway out seemed to get stuck in his throat.

He couldn't help but recall the time when he was a graduate student.

At that time, in his eyes, his supervisor also had this uncompromising aura!

But the person in front of him was just a sophomore student!

His supervisor was one of the top scientists in Xia Country at that time!

At this moment, not only Guan Hualiang, but also all the students in the audience were stunned!

"F... fuck, is Lü Yongchang crazy?"

A thin boy wearing black - rimmed glasses stared at the scene on the podium in disbelief and muttered to himself, "Is he... trying to get expelled?!"

This boy was named Wu Qi, Lü Yongchang's roommate. It was he who had woken Lü Yongchang up in a low voice just now.

He never would have thought that Lü Yongchang, who usually buried himself in study, would do such an astonishing thing in a college physics class!

...

Naturally, Lü Yongchang paid no attention to the shock of Guan Hualiang and his classmates.

He turned around, faced the blackboard, picked up the white - board marker in his hand, and firmly started writing!

A clear arithmetic expression appeared on the blackboard.

The handwriting was elegant, making Professor Guan Hualiang's eyes light up slightly.

One couldn't achieve this level of writing on the blackboard without several years of experience!

But soon, his brows knitted tightly.

This arithmetic expression shouldn't be knowledge that an undergraduate could come across!

A hint of curiosity flashed in Professor Guan Hualiang's eyes.

He stopped his action of trying to drive Lü Yongchang away and instead folded his arms and stood aside, quietly looking at what Lü Yongchang was writing on the blackboard.

As lines of arithmetic expressions and simple diagrams appeared, the deeper Guan Hualiang's frown became.

If he wasn't mistaken, this was related to controlled nuclear fusion!

But... how did this kid Lü Yongchang know about these things?!

However, seeing this knowledge that exceeded the level of undergraduates, the anger in Guan Hualiang's eyes had already dissipated, replaced by a strong love for talent!

This was a precious gem for the future of Xia Country!

Guan Hualiang looked at Lü Yongchang's straight back, his eyes filled with joy!

All of Lü Yongchang's slightly disrespectful actions just now were completely thrown to the back of his mind.

Geniuses! They always had some privileges!

Not to mention, the kid had apologized just now!

By now, the blackboard was densely filled with knowledge related to controlled nuclear fusion, including a simple diagram of the nuclear fusion device.

Guan Hualiang nodded in satisfaction.

The current research content of the controlled nuclear fusion project in Xia Country was almost at this stage.

Just as he was about to open his mouth to interrupt Lü Yongchang's actions, something unexpected happened!

Lü Yongchang suddenly stopped the white - board marker in his hand!

"There's no more space..."

Lü Yongchang knitted his brows slightly and turned his gaze to the projector screen beside him!

He moved his steps and wrote an arithmetic expression on the projector screen with the white - board marker!

The white - board marker wasn't suitable for writing on the projector screen.

But at this moment, Lü Yongchang clearly didn't care about such small problems.

He had an extremely urgent need!

He wanted to write down the storm of words in his mind on the blank space in front of him as much as possible!

Lü Yongchang wrote extremely fast. Before Guan Hualiang could stop him, a large area of letters had already appeared on the snow - white screen.

Before Guan Hualiang could feel heart - broken, the content in front of him attracted his attention.

This was...

Guan Hualiang's pupils constricted slightly.

This was the composition method of a new material!

Guan Hualiang subconsciously searched his memory in his mind.

But even after rummaging through his entire mind, he had no impression of this material at all!

"What... What on earth is this..."

Guan Hualiang muttered to himself.

The next moment, a flash of light reflected in the corner of his eye.

He followed the reflection and saw several classmates holding their mobile phones, recording the scene in front of them.

Guan Hualiang's face darkened slightly.

Although he wasn't sure what Lü Yongchang was writing now, his scientific research intuition told him that all these things were the most important essence!

They must not be leaked easily!

He snapped in a low voice, "Everyone, put down your phones and stop filming!"

After thinking for a while, Guan Hualiang added, "No one is allowed to leave the classroom without permission!"

...

Half an hour later.

Lü Yongchang slowly stopped his actions.

"What you wrote later, is it the synthesis method of a new material?"

Professor Guan Hualiang's voice came from the side.

Lü Yongchang turned his head, nodded, and smiled calmly. "Yes."

He glanced at the stunned classmates in the audience and lowered his voice, saying, "Professor, this material can solve the problems of controlled nuclear fusion."

Guan Hualiang's pupils suddenly constricted.

The biggest problem that plagued controlled nuclear fusion was nothing but the hundreds of millions of degrees of high temperature generated during the fusion reaction!

He turned his head again and looked solemnly at the projector screen filled with letters in front of him.

"What's the use of this material?"

There was a slight tremor in Guan Hualiang's voice. After all, he was a physics professor and didn't know much about materials science.

But... controlled nuclear fusion!

This was a problem that had troubled so many scientists!

Even though there was still a hint of doubt in his heart, seeing the densely packed and extremely detailed deduction steps here, that little bit of doubt in his heart also disappeared.

Such rigorous deduction steps, such skilled use of formulas...

He even suspected that the person standing in front of him was a hidden scientific giant!

"This material can perfectly withstand the high temperature of controlled nuclear fusion. Paired with a stellarator, it can perfectly achieve controlled nuclear fusion!"

Lü Yongchang's eyes flickered with a hint of ambiguous light, and he said in a low voice, "Professor, I need you to help me verify my deductions!"
