Popular science says oxygen is poisonous, and the whole internet scolds me for being sick

As for which one is the reason.

We don't know yet.

But judging from the current situation, their clan will not come out on the surface.

There must be a reason.

"What is the underground world like?"

“Is the center of the earth really hollow?”

“Is there a floating artificial sun inside?”

Ye Zhen rarely asked three questions in a row.

This was the first time that the audience saw Ye Zhen like this.

It was obvious that Ye Zhen wanted to know information about the underground world.

The future is bound to be entering the underground world.

Just like humans once landed on the moon.

Leatherta answered Ye Zhen's question.

"You finally asked."

"That's all I can say about the underground world."

"The complexity of the underground world is far beyond your imagination."

"Let me answer a question for you first."

"How can the underground world be hollow? There is no hollow artificial sun in the center of the earth."

“Such a structure does not exist in physics.”

Why did Ye Zhen ask this?

Because some scientists had crazy ideas before.

They believe that the center of our blue planet is a microscopic star.

This is the legendary artificial sun.

Our surface is something like a Dyson sphere.

Covering the entire blue planet.

Layer upon layer of strata, volcanoes, earthquakes and so on.

In fact, it is about the control and use of energy.

That's why Ye Zhen asked this question.

"Give you humans a brief introduction to the underground world."

"As for the underground world, even our race has many unexplored places."

"Why do I say the underground world is complicated?"

"Because in the underworld the biosphere is three-dimensional."

This is a bit like the land, sea and air in our current world.

But the three of sea, land and air are added together.

The vast majority of them are living spaces on the surface of the earth and in the ocean.

But this is only one percent of the surface of the blue planet.

That's why Leatherta says the underground world is very complex.

"In the underworld, there is no natural source of light."

"The only source of light is the lava river."

"There are also some radioactive ores."

"But in general, in the underground world."

"Super vision in dark environments is a must."

This is the biological characteristic caused by the environment.

The same is true for some creatures that live in caves.

Some of them have evolved super night vision capabilities.

Some use various methods to achieve similar effects.

For example, evolving a super strong sense of smell or hearing.

Used to replace the vision of your own eyes.

"Our eyes evolved to have double pupils for this purpose."

"It allows us to switch between different vision in various environments."

"The underground world is complex and intricate."

"But there are two places that need the most attention."

"These two places are also the most dangerous and the places with the greatest opportunities in the underground world."

"These two places are the remains of civilizations and races that are older than ours."

"In fact, your human world also knows something about these two places."

"Because you call these two places Mu Continent and Lemuria Continent."

"There are also fairy mountains, falling skies, moon fragments, and so on."

"No matter what it's called, it points to those two places." "Besides, there are some other dangerous places."

Now everyone can confirm it completely.

Everything Ye Zhen said in the previous show was true.

Are there really two such places in the underground world?

This was confirmed by Leatherta.

Ye Zhen nodded slightly, obviously satisfied with Lacerta's answer.

"Then can you tell us about the passage to the underground world?"

"Where are they? There are several of them." Ye Zhen asked directly.

But Ye Zhen prayed that Leatherta would say it.

After all, this is the passage to the center of the earth.

Leatherta seemed to laugh.

But the sound was like a leak, making it feel like he wasn't laughing.

"Do you want to explore the underground world?"

"Here, let us give you humans a piece of advice."

"Deal with the stuff above your heads before exploring the underground world."

"It's just that you want to know some entrances to the underground world."

“It’s just that these entrances were actually left over from a long time ago.”

"Some of the ages cannot be traced back to the beginning of this world."

"Let me tell you some of what you have discovered."

"Now, there is an entrance to the inner world at each of the north and south poles of the blue planet."

"There are two in China today, a lake in the south and the roof of the world."

"The American continent also has underground passages leading to the inner world."

"And there's one on the European side, too."

Has anyone ever thought that there are so many entrances to the inner world?

Professor Yan Xin was surprised to hear that there were actually two in our country.

"two?"

"In a lake in the south?"

"The other one should be the one under the Potala Palace that Mr. Ye mentioned in the previous program."

Professor Yan Xin analyzed in his mind.

Where exactly is the entrance to the other underground world?

Some foreign experts are also thinking about this.

"It turns out there is more than one entrance to the underworld."

"Didn't we talk about this in Ye Zhen's show before?"

"Some primitive tribes in America have friends who come from underground."

"I think it was called Anunnaki."

Some people remembered what Ye Zhen had said in his previous show.

Now they are slowly beginning to show up little by little.

Of course Area 51 of the United States knows.

Because some strange buildings and mazes were once excavated underground in New York.

A large amount of gold was found inside.

But they didn’t know that Ye Zhen had already mentioned this matter a long time ago.

Professor Zhou talks about the North and South Poles.

"As for the North and South Poles, the South Pole should be what Mr. Ye mentioned."

"The underground world of Antarctica is where Black Tai Sui is sealed."

"Where is the one at the North Pole?"

Professor Zhou and his colleagues remember very well what happened in the Antarctic underground world.

That is actually the entrance to an underground world?

Ning Xiu in Bureau 749 thought about the content of this episode.

"An entrance to an underworld on the European side."

"It should be the one about the Kola Superdeep Borehole, right?"

Song Xuan thought of what a scientist had said before.

Perhaps in ancient times, there were underground passages on the blue planet that connected various parts of the world.

At that time, humans could travel to all parts of the world through secret underground passages.

Not like what we think now.

Those ancient humans relied on building simple boats to cross the sea. (End of this chapter)
