When Wang Lin descended into the cave and met with Professor Erdan Wang Zhi, the three of them began to descend quickly, hoping to find a side cave in the shortest time, then drill in, find a Pisces trap, and finally reach

A bottomless abyss thousands of meters deep.

Erdan is responsible for being vigilant below and wary of monsters that may appear at any time. Wang Lin is responsible for observing the cave wall to see if there are any small holes on the side. Professor Wang Zhi can do whatever he wants.

Well, this is how the division of labor between the three is very clear.

The cave gets bigger as you go down. The diameter of the cave entrance is only six or seven meters, but when you reach a depth of about sixty or seventy meters, the diameter increases to at least twenty meters.

The cave is incredibly quiet and dark, and the depression one feels increases as the depth of the cave increases. But the cave is definitely not stuffy, and people inside can feel a slight rising chill.

Nourishing air flow.

There is airflow in the ancient well cave, which means that the cave is not closed, otherwise the air inside will be like stagnant water without any flow. Through previous investigations by my relevant personnel, there is something connected to the side wall of the Big Ear Eye bottomless abyss.

Many small caves and countless passages form an intricate passage network under the Big Ear terrain.

After listening to what Big Brother Wang Lin had said before, Erdan even wondered whether the man-made fortifications under the Big Ears terrain were often the same as the internal structure of human ears. The Big Ears terrain on the surface was the human outer ear, and the Big Ear eye was the "ear canal".

There are places representing the periosteum, tympanum, ear ossicles, cochlea and so on.

Of course, Erdan just thought about it and didn't take it too seriously. At this moment, he was falling rapidly in Big Ear's eyes, his heart was in his throat, and his eyes were staring at the endless darkness and holes below.

Now he just hopes that a hole will appear on the wall, and then he can drill into it and enter an underground world.

Professor Wang Zhi carried an infrared imaging camera and kept taking pictures of every scene in the cave. Through the infrared night vision goggles on his own eyes, he could clearly see obvious traces of artificial "excavation" on the cave wall.

This mark is quite common among us, and it has good flatness.

, even a little shiny as if coated with paraffin, and the overall shape is like a spiraling upward thread. The texture is extremely clear, and you can never knock it out with a hammer. In addition, there are pits along the spiral texture, which is

It looks a bit like it was chiseled out with a hammer.

Now Professor Wang Zhi really wanted to stop and carefully study the spiral patterns and small pits on the cave wall, but Big Brother Wang Lin said before coming down that he could not stay in the cave and must find a way out as soon as possible.

A side opening in the underworld.

In just one minute, the three people descended to a depth of one hundred meters. At this depth, when Professor Wang Zhi looked up, he could no longer see the sky above, except for a faint green formed by infrared imaging.

With a bang, the three nervous comrades bumped into each other and hit the cave wall. The camera in Professor Wang Zhi's hand almost fell out of his hand, and he was so frightened that he broke out in a cold sweat.

Professor Wang Zhi was not the only one whose anus was tight and sweating, Erdan and Wang Lin were also in similar condition.

Erdan was the worst. He was the first to be knocked down against the cave wall. Professor Wang Lin and Wang Zhi both knocked him down and then knocked down the cave wall.

"Holy shit, what's going on?" Erdan asked in shock.

Big Brother Wang Lin put his gun butt on the cave wall to separate his body from the cave wall. He looked up and said, "It's okay. The cave is starting to turn here. Going further down, the diameter of the cave will become larger and larger."

The bigger it is, the harder it will turn."

While talking, the three of them descended for a long distance along the cave wall at the original speed. Their helmets hit the cave wall and made a banging sound. Not to mention how miserable they were, their clothes were almost worn out.

"Brother Wang, hurry up and ask the people above to slow down the speed of the rope release. If this continues, people will be grinded to death." Erdan said with a gray head and a gray face. His body was flat and his legs were stepping on the cave wall. Every time he doubled his

When his legs exert force, his body will leave the cave wall for a certain distance, and then it will come closer to the cave wall under the action of gravity. Then his shadowless feet come into play, kicking against the cave wall desperately.

The worst one was Professor Wang Zhi. He hugged the camera tightly in his arms and huddled into a ball, letting his body rub against the wall. Seeing this, Erdan helped Professor Wang Zhi with one hand.

Grab the rope on his body and pull out.

Wang Lin and Er Dan made the same move, constantly pushing their feet against the cave wall to prevent their bodies from rubbing against the cave wall. At this time, he had already held the walkie-talkie in his hand and shouted: "The people above,

Can you hear me?"

"What the fuck, slow down!" Erdan shouted, grabbing the walkie-talkie from Big Brother Wang Lin's hand.

"I fainted." Professor Wang Zhi said with a gray face.

…

At a depth of 100 meters, no electromagnetic signals can be transmitted in the Big Ear Eye, and the signals inside can no longer go out. As a result, the walkie-talkie is no longer working.

Wang Lin had no choice but to find another way to communicate with the people above, using a flashlight to send out signals. He took the flashlight in his hand and pointed it at the top three times. After a while, the three of them stopped wiping the cave wall.

Come down.

At this depth, the thread-like curves on the cave wall became more obvious, like a spiral staircase. He huffed and gasped, tilted his head and looked down. He could vaguely see

The cave was getting bigger and bigger, like an empty underground world. The invisible sense of oppression he felt became stronger and stronger.

Wang Lin took out a small barometric sounding instrument from his pocket, took a look at it, and said: "It's 138 meters deep. We will soon be able to see the small cave on the cave wall. Everyone, hold on tight." Then he turned to Hui.

The gray-faced Professor Wang Zhi asked, "Professor Wang, are you okay? Um, why is your nose bleeding?"

Hearing what Wang Lin said, Erdan quickly looked away from the bottom of the cave and glanced at Professor Wang Zhi. He found that his nose was really bleeding, and a layer of skin had been wiped off the high tip of his nose.

Professor Wang Zhi sniffed hard and said: "A little injury, nothing serious. Well, Brother Wang, how deep did you say we went now?"

"138 meters. When you reach a depth of two to three hundred meters, you can almost find the small hole on the side. Just hold on for a while." Wang Lin.

"How deep are unknown vines found?" Professor Wang Zhi.

"It starts to grow at 200 meters, and becomes denser as you go down. But I would like to advise you, if you see a plant, never touch it with your skin." Wang Lin.
