The hands that have been carefully studied all year round have been maintained very ruddy.

The white coat on his body was clean and spotless.

As he thought, it was still the same familiar scene, and it was the same identity.

Rising from their seats in the research room, the researchers, who were hurrying back and forth with the encrypted files, just glanced at him and nodded respectfully.

"But it looks like the timeline is a little wrong."

Pushing the silver-rimmed glasses, his eyes narrowed slightly, and he looked up at the big screen in front of him, which was no longer a study of lithography machines, but involved some kind of high-precision computing and other projects.

"Chip project?"

"It seems that the timeline has really been pushed back a lot, and now the lithography machine technology in this country should be very mature, right?"

Chen Yuan just whispered, and didn't say a word to the people around him.

However, each simulation did not seem to have any relevant memories from before, so Chen Yuan could only be cautious.

At this time, a black jeep stopped outside the Second SMIC Research Institute, and three young men in guard uniforms got out of the car.

Takemi Miao came in a proud posture. The autumn breeze was blowing, brushing his cheeks, and it was still a little cold. With a bun on his head, the wooden hairpin was extremely special, with a hint of classical, "Professor Chen, the General Assembly Department needs you to go there, we are here to pick you up, please come with me." ”

"Hmm." Chen Yuan didn't feel surprised, maybe this was the NPC that asked him to continue the plot, but did the other party know that he was a witness to the emergence of the current civilization.

That kind of heart that looks at the world makes Chen Yuan seem as calm as water in the face of these people.

On the way to the general assembly department, Chen Yuan took the initiative to talk to Wu Jianmiao, and unexpectedly found that she was not very old, only nineteen years old, but the temperament on her body was not like that of a young man.

"It seems that the people here are very precocious."

Chen Yuan thought in his heart, and his eyes couldn't help but look out the window.

The rows of high-rise buildings are clearly no different from the metropolises of the 21st century.

The same road, the same zebra crossing, and the familiar office building.

There doesn't seem to be much progress in technology.

The only thing that puzzled Chen Yuan was that the cars did not emit exhaust fumes.

Electric?

"The cars in the simulated world are also four wheels, and they are not suspended in the air, but I always feel that the technology of this society should be improved, from which aspect?"

These doubts filled Chen Yuan's heart, but in the next moment, everything that Chen Yuan was curious about had all been answered.

After passing through a long, straight tunnel, the car sees the light again, and the surrounding environment changes from the city to the winding mountain road.

On the right is the green peak, but on the left is a very special sight under the cliff.

As far as the eye can see, there is a large area of reclaimed wasteland, and through the ruins, it is vaguely surmising that it was also an urban area not so long ago, but now the buildings are gone, and all kinds of large excavation machines stand in it.

The dust swept through the sky, and under this endless view, all kinds of potholes of various sizes were seen.

It is very appropriate to describe it with the word "full of holes".

"Why?"

"Why is this happening here, what is this digging?"

Chen Yuan frowned, and only felt a bad premonition in his heart.

"You don't know?"

Wu Jianmiao turned around and said a little strangely, "This is the Helium Three Industrial Mining Area. Industrial areas like this can be found almost everywhere in the world, uncle, are you confused in the research room? ”

Perhaps it was because Chen Yuan put down his closeness at the beginning, and Wu Jianmiao's address to him became playful.

"Helium...... Helium three? ”

However, Chen Yuan didn't have the attention to care what the little girl called him, but was shocked by the helium three in his mouth.

Is it the helium-3 I imagined?

helium-3,

A clean nuclear fusion feedstock.

In the real world, the amount of He3 stored on Earth is very scarce. On the contrary, there are very many helium-3s on the moon.

But now the simulated planet will actually mine a large amount of helium-three......

Chen Yuan was not surprised.

In the first simulation, Chen Yuan witnessed the evolution of this terrestrial planet, which for a long time had no atmosphere.

This gap in the atmosphere is longer than that of the Earth.

What does this mean?

Perhaps many people do not know why the Moon has more than 1 million tons of helium-3, but the Earth has only 0.5 tons?

In fact, this has a close relationship with the atmosphere.

This is where nuclear fusion takes place in the core region of a yellow dwarf star within a 1/4 radius, including the fusion of the deuterium nucleus and the deuterium nucleus, which combine to form helium-3!

And helium-3 will continue to fuse into more stable helium-4, but some helium-3 will gradually rise to the surface of the star with convection, and finally with the violent stellar activity of the solar wind is sprinkled into space, the yellow dwarfs in the star system do not favor the major planets, but the planet's magnetic field and atmosphere prevent helium-3 from falling to the surface of the planet!

This shows that the reason why the moon has a large amount of helium-3 is entirely due to their almost non-existent atmosphere, which can even be described as a high vacuum! This allows the solar wind to travel straight in!

The closer you are to a star, and the more you don't have an atmosphere, the more helium-3 you will have on that star!

Everything can be explained, this terrestrial planet has more than three helium accumulations before the formation of the atmosphere at that time.

But it also means the fact that helium-3 is a non-renewable energy source on this planet.

According to the clues obtained, Chen Yuan seems to be able to construct a set of current social and technological development maps in his mind.

The world has officially entered the age of atoms at its purest and higher level!

That is, the era of nuclear fusion that the human race of the earth is looking forward to.

The fact that the cars do not emit exhaust gases means that these cars no longer use oil, but nuclear fusion.

"I see......"

Chen Yuan muttered.

"It feels like you're seeing you for the first time."

"But speaking of which, this is also a landscape of the home of all mankind."

"If it weren't for the discovery of more than 10 million tons of helium-3 by the scientific expedition team ten years ago, perhaps it would not have entered the nuclear age so quickly."

Takemi Miao seems to be telling an ordinary thing.

Chen Yuan couldn't sit still.

"What, ten million tons?"

"yes, 10 million tons."

"Ten years ago, the world's oil reserves were empty, and in search of oil, world governments set their sights on Antarctica."

"At that time, when the scientific expedition team was drilling deep in Antarctica to extract oil, it discovered a 300,000-ton natural helium triple well at a depth of 10,000 meters underground. Finally, in the five-year scientific expedition, it was estimated that the total amount of helium-3 on our planet has reached more than 10 million tons, or even more. ”

Wu Jianmiao seemed to have gotten used to Chen Yuan's knowingly questioning.

"Just kidding......"

Chen Yuan swallowed his saliva, obviously having a hard time accepting this fact.

You must know that the amount of helium-3 on the moon is only about 700,000 tons, which is only enough for the earth to use for thousands of years!

The concept of 10 million tons may be more straightforward.

And this 10 million tons is only detectable by humans.

If what Wu Jianmiao said was true, Chen Yuan could already guess what the reason behind this was.

It is absolutely impossible to store so much helium-three just from the prehistoric solar wind, and now this terrestrial planet no longer has the conditions to collect helium-3 in interstellar space.

Then the helium-3 on this terrestrial planet is basically made of tritium nuclei!

That is, super heavy hydrogen is transformed through β decay!

This is also the reason why there are small sources of helium-3 on the planet.

And if you want to achieve this condition, perhaps the core of this planet is itself a huge tritium core!

Chen Yuan didn't feel happy, but completely panicked!
