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

Professor Zhou also thought about this aspect.

It’s just that he deduced it backwards from the records in some ancient Chinese books.

"There is a so-called Dragon Palace in the sea, and there is a so-called Heavenly Palace in the sky."

"There is also the underworld and the hell underground." Professor Zhou listed them all.

Si Xiaoping said, "If that's the case, the underworld is the most difficult place to go."

Old Wu responded, "Isn't the underworld a place where only the dead can go?"

"In theory, it is indeed the most difficult to get to."

It is easy to go, but difficult to come back.

Back to the show.

Ye Zhen continued to educate everyone about the Soviet Union's excavation of the Kola superdeep borehole.

“Are you wondering why the Soviet Union gave up the Kola Superdeep Borehole?
And after giving up, Russia took over for a while.

There have indeed been many rumors out there.

Funding is insufficient and technology has reached its limits.

Some also said that there was no point in digging deeper.

However, these statements are just external rhetoric.

In fact, the former Soviet Union did dig out some other things back then.

Just when they had just broken through 12,000 meters.

They picked up some strange noises on the monitoring equipment.

Those sounds had never appeared before.

Scientists in the former Soviet Union were also curious at that time.

Why did some strange noises suddenly appear?

They were curious and played the collected sounds.

Then a strange scene appeared.

The oscilloscope shows that these sounds seem to be chaotic.

But when it is played.

Everyone present had a chilling feeling.

They felt that it was not a sound that could be made by any living creature on the blue planet.

There is no such strange sound even in nature.

Originally this was a secret back then.

If you have ever known about it.

You should all know this urban legend.

Because it’s a weird recording.

For those who have heard it, it sounds like someone wailing.

There are countless wronged souls screaming.

Gradually, people outside began to say that the former Soviet Union had dug up the gate to hell.

That recording is the sound from the gate of hell.

Others said that after listening to that audio clip.

I had hallucinations, as if I saw the devil.

Anyway, it is spread like a myth. "

The sound of Hell's gate?
Instead of feeling scared, the audience was very curious.

"Wow, did the Soviet Union really dig up the real stuff back then?"

"The gate to hell can't be that shallow."

"Did we dig up some strange creature?"

"No living creature can possibly survive more than 12,000 meters underground."

Some viewers were very curious about this audio clip.

But anyone who has watched Ye Zhen’s show will know.

Sound has special power.

Ye Zhen smiled and said, "I happen to have that recording from that year."

"Are you interested in listening?"

Some viewers were very secretive and immediately covered their ears.

It seems like I don't want to listen to the voice from hell.

They don't want to have nightmares when they sleep at night.

But more viewers are very curious.

What does the sound from hell sound like?

Some staff members at the scene began to get a little scared. Producer Chen and Director Chen glanced at Ye Zhen at the scene.

"The voice from hell won't summon something bad, right?" Director Chen asked a little nervously.

"Don't worry, if there is any problem." Producer Chen was not worried at all and patted Director Chen on the shoulder.

"Director Ye will never let anyone hear it."

Then a strange recording started playing on TV.

Roar!
At first it was like a howling strong wind.

The frequencies are very high and harsh.

If you listen carefully, it really sounds like someone is wailing.

There's a creepy feeling.

Then there was a screaming sound.

The sound seemed to come from the underworld and was totally unlike any sound a human could make.

This short sound is enough to be used as dubbing in some horror movies.

The recording was very short and finished playing very quickly.

Some audiences felt this way after listening to it.

That's it! ?
"Huh? That's it? I thought it was something else."

"Maybe it's just the sound of digging when drilling."

"It could also be the sound of the wind. After all, we dug more than 12,000 meters."

"It's not that scary, it's just a normal audio clip."

But some viewers were still frightened.

They felt that there was a deep sense of horror in that audio clip.

It was as if there was something terrifying there.

"Don't you feel terrified? I have goosebumps."

"That's right, this is clearly the sound of hell!"

"I think this is the wailing sound of countless souls being tortured by the flames of hell."

“Could it be that the former Soviet Union really dug into hell?”

In Bureau 749, Ning Xiu and others also heard this strange sound.

"If it was just a sound, they wouldn't give up so easily."

"Old Chen, do you know anything else?" Ning Xiu turned around and asked Old Chen.

This was not the first time that Lao Chen had heard that recording.

Old Chen had already heard it once before.

It just sounds like this now, many years later.

This audio clip still carries a suffocating atmosphere.

"Yes, if it's just a simple horror audio clip."

“It’s simply not enough to stop them from drilling.”

"The problem is, they didn't just encounter this strange sound." Old Chen paused and didn't continue.

Song Xuan was thinking silently while eating potato chips.

"Did we really encounter someone from the underground?"

"That's not right, if we encounter someone from underground."

"There should be a fight. We should just close that place off."

“That small drilling hole is not big enough for anyone to get in.”

"Could it be that the underground man is a small one?"

Like in some high pressure and high temperature environment.

The organisms there must be resistant to high temperatures and high pressures.

In some of our film and television works, underground people are generally very short.

The eyes are usually red and have amblyopia.

Because in the dim environment underground, vision has deteriorated to the point where it is unusable.

So they all thought that the underground people were short and blind.

This is inferred based on the environment in which organisms live.

But Song Xuan always felt that this was not right. It should not be that they encountered an underground civilization.

Because the underground civilization possesses advanced technology that surpasses ours.

Their living environment must be no worse than ours.

As for what kind of sound from hell this was, Song Xuan felt it was nonsense.

"Is it fake?" Song Xuan thought of a possibility, "Is it artificially fabricated?" (End of this chapter)
