It's reasonable for me to have a two-way foil for a second-level civilization, right?

Seeing that Yuan Lao frowned and did not object, Su Cheng swallowed slightly and began to explain.

"Professor Lu, I won't say much about the difference between fusion reactors and fission reactors. You must know more about this than I do."

Lu Yongchang nodded slightly.

Su Cheng continued: "In the fission reactor, we only need to manipulate the control rods in the fission reactor to compensate for fuel consumption and adjust the reaction rate."

"But fusion reactors are different."

"In a reactor, the motion of high-temperature plasma is extremely complex."

"And this involves a problem that has plagued the physics community for decades, the problem of turbulence."

"In other words, it is the Navier-Stokes equation (NS equation)."

"To achieve perfect control of the high-temperature plasma in the reactor, we must thoroughly grasp the NS equation."

"This is the reason why the nuclear fusion master control program has been unable to be completed."

Chapter 36 Existence and Smoothness of NS Equations

After listening to Su Cheng's words, Lu Yongchang suddenly realized!

No wonder the main control program has not been completed!

He clearly remembered that when the controllable nuclear fusion was conquered in the previous life, the research team did not encounter difficulties in the main control program at all!

Therefore, he did not go to understand the master control program of nuclear fusion in detail.

He didn't fully understand until now!

If nothing else, the existence and smoothness of the NS equation will be solved by a mathematician in the United States in about five years.

And now...

Without theoretical support, the main control program is naturally difficult to develop.

Fortunately, Lu Yongchang had done some research on the NS equation at that time, and he also had some impressions of the original proof process.

Lu Yongchang chuckled lightly, nodded and said, "I see... is there any paper here?"

With such a quick turn, Yuan Hongwei and Su Cheng didn't react for a while.

"Ah? What?" Su Cheng looked at Lu Yongchang puzzled.

How to do it so well, you need paper?

As for Yuan Hongwei, after hesitating for a moment, he gently pointed to the napkin on the desk: "Does Professor Lu want that?"

Lu Yongchang: "..."

"Ahem! I mean, the kind of paper for writing, A4 blank printing paper is fine."

While speaking, Lu Yongchang took out the pen he carried with him from his pocket.

Seeing Lu Yongchang's actions, Yuan Lao frowned, looked at him strangely and said, "Professor Lu, you don't mean to solve the NS equation here?"

Lv Yongchang chuckled, pulled aside the chair beside him and sat down: "Of course!"

"So, do you have A4 paper?"

While winking at Su Cheng, Mr. Yuan said hesitantly: "Professor Lu, the NS equation is not an ordinary thing, it is one of the seven millennium problems!"

Lu Yongchang reached out and took the stack of blank A4 papers handed over by Su Cheng, and nodded nonchalantly: "Of course I know!"

As he spoke, Lu Yongchang lowered his head, and briskly wrote a line of calculations on the A4 paper with the pen in his hand.

"This...Old Yuan, what should we do now?"

Su Cheng walked up to Elder Yuan and asked softly.

Yuan Hongwei didn't reply, but frowned and looked at the line-by-line calculation formula written by Lu Yongchang.

Time passed little by little.

The stack of A4 papers in front of Lu Yongchang has fewer and fewer blank spaces, replaced by dense and obscure calculations.

The suspicion in Yuan Hongwei's eyes gradually dissipated.

When he saw that Lu Yongchang wrote down a line of important calculations, his eyes instantly showed some surprise.

"Wonderful!"

Afraid of disturbing Lu Yongchang in front of him, Yuan Hongwei lowered his voice and said softly: "So this step can be deduced like this!"

As for Su Cheng, he was already confused, and his brain couldn't keep up with Lu Yongchang's writing speed!

……

Two hours flew by.

The rustling of pens in the main control room suddenly stopped.

"call……"

Lu Yongchang exhaled deeply, then stood up and stretched his muscles.

"The proof...is the proof?"

Yuan Hongwei's trembling voice of inquiry came from the side.

Lu Yongchang smiled and sorted out the A4 paper in front of him, and handed it to Yuan Hongwei.

"Of course!"

"Knot... what is the result?"

Hearing Yuan Hongwei's question, Lu Yongchang said with a smile: "Existence, it's smooth!"

Yuan Hongwei's face turned red instantly: "Professor Lu, you really..."

For a while, Yuan Hongwei couldn't find a word to describe Lu Yongchang in front of him.

"Now, the nuclear fusion master control program should be solved?" Lu Yongchang asked with a smile.

Yuan Hongwei nodded vigorously, with excitement flashing across his eyes.

"Of course!"

"Professor Lu, don't worry! If I can't solve the master control program of controlled nuclear fusion within half a month, you can ask me!"

……

US White House.

There was a roar in the presidential office!

"impossible!"

"Absolutely impossible!"

"fake news!"

Albert's face was flushed, and with a head of golden hair, he slapped the desk in front of him vigorously.

"It is absolutely impossible for Xia Guo to complete such a huge project within three months!"

"Everything is fake! Fake news!"

"Huh...huh..."

Perhaps it was because he was too emotional just now, Albert's old face was swollen like a monkey's butt, and he was panting hard.

"Mr. President, I regret to inform you that this is true."

Shrugging his shoulders, William Blair, director of the CIA, took a step forward, opened the laptop in his hand and placed it in front of Albert.

"what is this?"

Looking at the obviously accelerated construction video on the laptop, a hint of doubt flashed in Albert's eyes.

"This is the official three-month live broadcast video of Xia Kingdom." William Blair explained blankly, "From the video, it can be seen that in just three months, Xia Kingdom built the A complete nuclear fusion demonstration reactor has been built."

After watching the whole video, Albert's face turned green!

"Where did this video come from?"

William Blair was silent for a while, then replied: "Mr. President, this is the video that appeared on Twitter this morning."

"After identification, the video does not contain any false elements."

Albert's face turned greener when he heard that the source of the video was Twitter!

"Where's my phone? Show me what's on Twitter?!"

While talking, Albert hurriedly grabbed the phone, and his fat fingers struggled to land on the screen of the phone.

"God, Xia Guo is so crazy, he completed this kind of construction task in three months!"

"Jesus! Now I believe in the title of infrastructure madman of Xia Kingdom!"

"Don't talk about Xia Guo, where are the fusion experiments in our country? @艾伯伯特"

"Haha, the fusion reactor in the United States? I guess it's still on the blueprint?!"

"@Albert, Mr President, we need an explanation!"

Looking at the comments on Twitter, Albert's face darkened.

"Professor Collins! Is Professor Collins here?!"

As Albert's shout fell, a gray-haired old man leaned on a cane and squeezed forward, bent towards Albert in fear and said, "Your Excellency, I am here."

"Hmph!" Albert snorted angrily, "Tell me, where is our fusion reactor construction plan?"

There was a bit of anxiety in the old man's eyes.

"Currently...the construction has not yet started!"

"Puff... cough cough cough!" Albert spit out the Coke in his mouth, coughed hard for a while, and then looked at Professor Collins angrily.

"Professor, are you kidding me?"

"It's been more than three months. Is our fusion reactor still on the map?!"

"Listen, from now on, build me a fusion demonstration reactor immediately!"

Collins' complexion changed slightly: "Mr. President, our plan is a nuclear fusion experimental device..."

"The plan has changed!" Albert waved his hand and shouted loudly, "What Xia Guo can do, we can do too!"

"From now on, build me a demonstration pile!"

Chapter 37 Unexpected Situations

A month later.

Xia Guocang Bay.

The sea was calm, and an aircraft carrier quietly docked in the sea more than ten kilometers away from the shore to "repair".

When the camera is zoomed in, you can clearly see the naval guns and missile ports on the deck of the aircraft carrier, all of which are in the open state!

Inside the aircraft carrier, the all-weather radar is running at maximum power!

In the eyes of outsiders, this war fortress is simply docked for repairs.

However, it is ready to attack at any time!

On the shore, countless garrison soldiers patrolled the designated area in an orderly manner.

Every soldier, the safety of the gun in his hand has been fully opened!

Since two days ago, the area of ​​Canghai Bay has completely entered the state of military control!

It is no exaggeration to say that in Canghai Bay at this time, even a dog would be slapped twice for passing by!

The reason for all this is that the Pangu No. [-] fusion reactor on the shore of Canghai Bay will start its first ignition test in the near future!

……

The main control center of the Pangu No. [-] fusion demonstration reactor.

Lu Yongchang stood on the central console with a serious face, staring at the various data on the big screen in front of him.

"Ready to start the first ignition!"

Lu Yongchang exhaled slowly, and said in a deep voice, "Attention all departments, start checking the operation of various equipment!"
