The experimental machine comes out.

Fang Xu looked at Lv Yongchang in front of him with a complex expression, and the ballpoint pen in his hand trembled slightly.

Solid lithium is already dangerous, let alone liquid lithium heated above 180.54℃!

Now, Lv Yongchang was actually telling him that they were going to use liquid lithium as the reaction solution for controlled nuclear fusion?!

That was nuclear fusion!

The most violent reaction in the entire star system!

Not only Fang Xu, but all the researchers and professors around also had strange expressions on their faces after hearing that liquid lithium was to be used as the solution.

"Ahem..."

"Professor Lv, how about... we think about it again?"

Lu Hezheng beside him cleared his throat and persuaded in a good - natured way.

Lv Yongchang swept his eyes around and, seeing everyone's expressions, a hint of bitterness appeared on his face as well.

Well, to be honest, he also thought this plan wasn't very safe.

But which experiment related to nuclear physics was truly safe?

Lv Yongchang pondered for a moment, then walked over to the demonstration whiteboard beside the laboratory.

He reached out and picked up the black marker pen beside it, and wrote a string of complex and beautiful formulas on it.

"Everyone, this is the mathematical model of sonoluminescence."

"To ignite nuclear fusion in the solution, we must make the temperature of the bubble collapse reach hundreds of millions of degrees Celsius!"

"And only liquid lithium can achieve this!"

As he spoke, Lv Yongchang's right hand waved quickly, writing down the detailed deduction process on the whiteboard.

Fang Xu looked at the formulas on the demonstration whiteboard thoughtfully and nodded slightly.

As one of the top academicians, Fang Xu quickly followed Lv Yongchang's train of thought and got the answer.

He let out a soft sigh and said helplessly, "If the mathematical model is correct, then liquid lithium might really be our only choice."

Lv Yongchang chuckled, "In my opinion, liquid lithium is not a choice made out of desperation."

"On the contrary, it is the best choice for a small - scale fusion reactor!"

As he spoke, Lv Yongchang wrote a symbol heavily on the demonstration whiteboard.

Li - 6!

The moment he saw this symbol, Fang Xu's pupils suddenly constricted!

He understood!

He understood everything!

"Yongchang, you're going to utilize that physical property of lithium - 6, right!"

A glint of excitement flashed in Fang Xu's eyes, and he subconsciously stretched out his right hand and rubbed his nose hard, "Yes! Yes! You're right!"

"Liquid lithium is the best choice for a small - scale fusion reactor!"

Seeing the excited Fang Xu, a hint of amusement flashed in Lv Yongchang's eyes.

As expected of Fang Xu!

He grasped the key point in an instant!

Unlike Fang Xu, the researchers and professors around were looking at Lv Yongchang with confused expressions at this time.

Lv Yongchang naturally didn't keep them in suspense for too long and directly started to explain.

"Lithium - 6 atoms have a physical property that is easily overlooked."

"When bombarded by neutrons, it releases tritium atoms."

Upon hearing Lv Yongchang's explanation, everyone's expressions froze!

So that's how it is!

Once the deuterium - tritium fusion reaction is triggered, it will naturally release a large number of neutrons!

And after these neutrons bombard the surrounding liquid Li - 6, the liquid Li - 6 will release a large number of tritium atoms!

In this way, compared with the Pangu - 1 fusion reactor, the small - scale fusion reactor doesn't even need to replenish tritium gas. It only needs to regularly replenish the cheapest deuterium gas to maintain the operation of the fusion reactor for a long time!

"Yongchang! I'll contact the factory right away!"

Fang Xu said excitedly, "I didn't realize it just now, but now it seems that this is simply the best solution to miniaturize the fusion reactor!"

...

Three days later.

On an open space one kilometer away from the No.1 Laboratory of China, a huge iron - sheet factory building was erected out of thin air.

In the center of the factory building was placed a dark - colored cylindrical container.

The container was about two meters high and about one meter in diameter.

At the bottom of the container was a huge ultrasonic generator.

This seemingly simple container was the experimental machine of the small - scale fusion reactor.

Looking at the device in front of him, a hint of sentimentality flashed in Lv Yongchang's eyes.

It had to be said that after pooling most of the resources of China, the progress of the experiment had been accelerated indefinitely!

Three days ago, as soon as Fang Xu finished contacting the factory, the blueprint of the experimental machine of the small - scale fusion reactor was placed in front of Lv Yongchang within just one hour!

Next... China not only completed the manufacturing of the experimental machine within three days, but also, for safety reasons, specially erected an iron - sheet factory building on the open space to serve as a temporary experimental site.

"Yongchang, when shall we start the experiment?"

Fang Xu turned his head to look at the experimental machine in the center of the factory building, a glint of eagerness flashing in his eyes.

This was a small - scale fusion reactor!

As a top academician in the field of nuclear fusion, Fang Xu knew better than anyone the value of this thing!

Unlike large - scale fusion reactors, small - scale fusion reactors would not be used in the civilian field. They would only shine in the military field!

Thinking that in the future, China's aircraft carriers, submarines, or fighter jets would all use nuclear fusion as an energy source, Fang Xu's heart began to beat violently.

"Not in a hurry. We'll wait for someone first."

Lv Yongchang's indifferent words came from the side.

"Wait for someone?"

Fang Xu was taken aback and subconsciously asked, "Wait for whom?"

Lv Yongchang's gaze passed over Fang Xu and looked into the distance, "Look, here they come!"

Fang Xu quickly turned his head and looked in the direction Lv Yongchang was looking at.

I saw a black Hongqi car slowly driving towards the location of the iron - sheet factory building.

The license plate number was, of course, that familiar string of numbers.

"Is the councilor here?!"

Fang Xu was shocked and exclaimed in a low voice.

"Let's go!" Lv Yongchang straightened his clothes, "We should go and greet him!"

...

"So small?!"

"Yongchang, are you sure this thing can carry out controlled nuclear fusion?!"

As soon as he saw the experimental machine, Councilor Li questioned Lv Yongchang.

Facing the question, Lv Yongchang naturally replied with a smile, "Councilor, this thing doesn't depend on its size!"

"This is just an experimental machine. If it's successful, its volume can be made even smaller!"

"At that time, it can even be installed in your car!"

Councilor Li smacked his lips. Obviously, he didn't quite believe Lv Yongchang's words, "The power generation capacity of this thing should not be comparable to that of Pangu - 1, right?"

Lv Yongchang's expression froze.

This was obvious, wasn't it?!

What was Pangu - 1?

It occupied an area of 20 square kilometers!

How big was this small - scale fusion reactor?

Seeing Lv Yongchang being at a loss for words, Fang Xu beside him couldn't help but show a knowing smile.

However, although he was smiling, as a subordinate, he still needed to help explain and defend when his superior was in an awkward situation.

"Ahem, Councilor, different sizes mean different powers." Fang Xu took over the conversation, "According to estimates, the power of this small - scale fusion reactor in front of you should be around 1000 megawatts."

The councilor's eyebrows shot up.

1000 megawatts!

That was quite a large power capacity!
