"Be careful!"

"Watch your step!"

"Yang Yu, keep up!"

"The lights are brighter, hell, this underground cavern is so dark that no sunlight can penetrate at all...... How deep have we come down? I'm afraid it's two or three hundred meters, right? ”

"It's a tough road!"

In the dark cavern, where you can't see your fingers, four searchlight beams shine in all directions.

The beam of light shines, illuminating the craggy rocks in the cave, and the hideous cave rocks have different shapes, forming a lot of terrifying and weird scenes that only appear in horror movies, and setting off the already oppressive cave atmosphere even more.

From time to time, Yang Yu and the others could see some sharp stalactites like razors hanging down at the bottom of some stones.

It's very slippery underneath!

There is an abyss of unknown depth, surrounded by stalagmite spikes as sharp as razors.

Even the only four light sources can't reach far enough distance before the endless darkness swallows up the light!

The lack of vision and the dangers around them made everyone feel depressed and irritable...... Even the tone of his voice gradually became rude and irritable.

In normal times, these people are at least very decent on the surface.

After all, they do a decent job.

These four people, including Yang Yu, are all part of a well-known archaeological expedition team in the industry.

This time, the leader of the team is the well-known Professor Li!

Professor Li is a real expert in the field of archaeology, and it is difficult for ordinary people to even meet him, and even if the three archaeological veterans like Yang Yu and the other three have limited opportunities to contact Professor Li.

This time, when they learned that they could act with Professor Li, Yang Yu and the others had been excited for a long time.

That's an idol!

And now...... In front of their idols, the three of them couldn't help but burst into foul tempers, but it is conceivable that the oppressive atmosphere inside this cave has compressed everyone's nerves to a critical point.

If you don't touch the bottom of the cave, I'm afraid there will be problems!

Silence.

A group of four people climbed down the rock with difficulty.

As time passed, at least fifteen minutes later, even their interest in occasionally speaking rudely disappeared at this moment, and they were extremely depressed! Inside the cave, apart from the sound of water droplets splashing on the rocks, there are only footsteps, and ...... A few searchlights were scattered.

Smack!

Suddenly, an exceptionally bright and clear sound of footsteps landing sounded!

The sound of the foot is obviously not something that can be made by stepping on the uneven rock, but by falling on a flat ground!

"I'm going to get to the bottom of it!"

"The ground is so flat, oh my God! This place...... What the hell! One person shouted, and a searchlight at the bottom of the crowd was even more frantically sweeping up and down, left and right at this moment, and the light pierced the darkness like a thick laser beam!

The person who shouted and spoke was Yang Yu!

"Yang Yu, what's wrong?! Did you reach the bottom of the cave? ”

"What did you find? Tell me about it! ”

"Don't mess around! Stabilization! ”

"Make it clear! Hurry! ”

One stone stirs up a thousand waves!

The other three shouted nervously as Yang Yu shouted.

Even, Professor Li, who had been silent, couldn't help but speak out!

At the same time, Professor Li and the three of them also quickly climbed down...... Yang Yu went down some distance before the three of them, as a pathfinder. Professor Li and the three are one step behind.

At this moment, they quickly climbed down, and soon descended to the position where Yang Yu was.

As soon as they landed, several people were stunned after a burst of searchlights shot over their heads......

And Yang Yu stood not far away, in front of a huge shadow!

That's an old book!

Unknown material, black cover, but at least the size of a small house...... Huge old books!

This is an ancient ruin that has been left behind for an unknown amount of time!

……

Ten minutes later.

Professor Li stood in front of a stone wall in a daze, and the searchlight above his head shone out the murals on the stone wall in rows!

The bottom of the dark cave is silent.

Everyone consciously closed their mouths at this moment, and the scene in front of them made them completely stunned!

Especially when I saw the huge scenes on the stone wall in front of me, the war murals in an abstract or realistic style...... That scene was like an interpretation of ancient mythology, which made Yang Yu and the other four all have a sentence in their minds!

They are developed!

Inside this natural cave, there are really discoveries!

And...... At the moment, it seems that this discovery is quite unusual!

Yang Yu turned his head and glanced at the shadows not far away.

There, the strange object that resembled an ancient book, but with a huge house-like volume, was still quietly supported by some stones.

"Professor Li, the font around these murals is so strange, can you recognize what era of writing this is?" Among the four, a bespectacled young woman in her early twenties, asked.

Her name is Bai Xiaohe, and she is the only woman among the four. Her appearance was very ordinary, and the glasses on her face were carefully tied with an elastic rubber string and fixed to her head.

After all, you have to climb up and down, which is also to prevent the glasses from falling.

"It's weird."

"Something resembles hieroglyphs, but it's certainly not." Professor Li frowned, his eyes shining surprisingly brightly in the darkness as he walked to the wall carved with large murals as he spoke.

Rustling.

Professor Li was silent, stretched out his hand and groped for the rock wall, grinded some stone powder, put it in his mouth and tasted it, and carefully examined the texture of the surrounding rocks.

"I don't recognize the words."

"But...... These murals are probably more than 100,000 years old...... This discovery will rewrite history as we know it! ”

"100,000 years?!" Yang Yu's eyes immediately widened, and their eyes were full of incredulity.

Although these murals are scribbled and wild, they obviously have a certain degree of painting attainment.

Those huge ancient books should not have appeared in such a distant era......

100,000 years ago.

At that time, mankind was still in the ancient age of ignorance......

Yang Yu and the others were shocked and speechless, and the cave also fell into a deathly silence for a while.

Bang!!

Suddenly, there was a loud bang, followed by a violent shaking inside the cave, and small pieces of rubble fell from the roof of the cave!

"What's going on!"

"Earthquake?" Yang Yu shouted.

Everyone woke up like a dream, and at this moment they also screamed, while quickly approaching the nearby mural stone wall to dodge.

"Protect your head and watch out for the gravel above your head!"

While dodging, some people kept shouting to remind the people around them.

At this moment, the cave is noisy!

Rumble!

Boom!

Under the violent vibration, some huge stones fell from the top of the cave from time to time, shaking the ground, and Yang Yu and his party were like a small boat in the deep sea at this moment, which could capsize at any time, and there was a danger that the boat would be destroyed and people would die!

The mountains shake!

Yang Yu raised his head, and the searchlight beam above his head shone out dozens of meters away like a thick laser beam that tore through the darkness!

The beam swept and scattered, temporarily illuminating a large area of the cave above Yang Yu's head.

At this moment, between the beams of light, sharp and small stones are constantly shuttling and falling!

Suddenly, Yang Yu's eyes shrank and shouted, "Get out of the way!" ”

Swish!

As soon as Yang Yu's scream came out, the whole person had already rushed out towards the left side of the stone wall, and even fell out directly due to the excessive momentum, he rolled on the ground one after another, grinding a large piece of clothes and pants on his body, and the blood between his chest and abdomen was torn by the ground gravel!

However, with such a serious injury, Yang Yu didn't pay any attention at the moment, and as soon as he came back to his senses, he looked back at the place where Professor Li and the others had been hiding.

Thundered~~~~~

The black shadow flashed, and a violent sound slammed into the ground, shaking the entire cavern as if it was about to collapse!

Yang Yu's heart also sank suddenly.

That shadow is a boulder!

Broken and fell from the top of the cave, a huge boulder more than ten meters high!

And the landing point of the boulder happened to be in the position where Yang Yu and his party had just dodged......

If Yang Yu didn't just look up and see the situation on the top of the cave and dodge it at the last moment, then ...... When Yang Yu thought of this, a layer of fine goosebumps appeared on his back, and cold sweat trickled down.

"Professor Li!"

"Bai Xiaohe!"

"Li Qiang!"

"You're not there? Hear a reply! Ignoring the pain on his body, Yang Yu immediately shouted in the direction of the boulder.

At this moment, the echo formed after the boulder fell still echoed inside the cave, and gradually weakened and smaller...... But other than that, there was silence.

Except for the occasional vibration under his feet and the soft sound of some small stones falling to the ground, only the echo formed after Yang Yu shouted...... Professor Li, Bai Xiaohe and the other three had no news.

"Damn!" Yang Yu closed his eyes and clenched his fists.

Professor Li: It seems that they are more than lucky.

"I need to get out of this place." Yang Yu held his hot chest with one hand, trying his best to hold back the blood that was constantly bubbling out, while the other struggled to support the ground, trying to stand up. But after he tried it, he was just halfway up when there was a sharp pain in his right leg with a soft click!

Bang!

In the dark cave, after a muffled sound, Yang Yu fell into a rolling gourd.

"Ahh My leg! Yang Yu let out a cry of pain, and the echo continued to stir inside the cave.

His right leg is broken!

This fall, coincidentally, Yang Yu fell directly under a huge shadow.

Underneath that ancient book as big as a house!

Pain!

Drill the heart to the bone!

Yang Yu whispered, and almost half of his body rushed into the gap between the several stone piers that supported the ancient books with inertia......

Bubbling -

His right leg was fractured, and he suffered extensive contusions all over his body, and at this moment Yang Yu was already injured to the extreme.

The bright red blood in Yang Yu's body also sprayed out like crazy money along the large and small wounds all over his body at this moment. As the blood was drained heavily, his vision gradually blurred.

"I, Yang Yu, am actually going to die in such a place?"

"I'm so unwilling...... Yang Yu lay on his back, his slightly blurred vision overlapped with the huge ancient books above, he felt that his life was passing rapidly at the moment, his physical strength was almost exhausted, and his consciousness was blurred as blood flowed out like opening the floodgates.

There were even hallucinations......

Like what...... At this moment, in his sight, he saw that the huge ancient book suddenly lit up with a bright white misty light!

The light swept across the room, and an invisible force lifted the blood flowing from the ground like a big hand.

Subsequently...... The ancient book was like a gluttonous beast, and it greedily sucked up the blood from Yang Yu.

"It's ...... Hallucination? Yang Yu's vision became more and more blurred.

"Wait!"

"That's not right!" Yang Yu was full of excitement, and the whole person was completely awake as if cold water had been poured from the top of his head to the bottom of his feet. Now when he looked at the ancient books above his head, those hallucinatory visions were still there, and they were getting worse!

Thundered~~~~~~

A terrible tearing sound appears!

Under Yang Yu's stunned gaze, the huge ancient book was forcibly opened by an invisible force.

Whoa, whoa, whoa!

Between the pages of the book, golden light tore through the void!

In the blink of an eye, a giant black hole appeared that cracked like a baby's lips!

The next moment, the black hole shrouded down like the bloody mouth of a giant beast, and the ancient books the size of the house, Yang Yu ...... and the surrounding stone piers are all swallowed up!

Wow~~~~~~~~

The wind is blowing in the cave!

After a few moments, everything subsided.

The light source in the cavern dissipates and returns to darkness.

And that huge ancient book with Yang Yu ...... It's gone!
