"It's as if someone deliberately brought us here, but didn't show us anything, and then spread his hands and said, 'Look, there's nothing, you're too worried,' to prove 'his' innocence." After Zhou Ran finished speaking, he couldn't help but look around.

A complicated expression flashed on Yu Lie's face, an expression between panic and innocence.

"Professor Zhou, you have confused me, and when you say 'he', you mean ......"

"It's nothing," Zhou Ran said with a smile, "It's just my feelings about this matter, maybe it's just cranky." Captain Yu, what should we do now? ”

Yu Lie thought for a while and said, "Let's rest here for a while, eat something, and then see if there is a way out nearby." If not...... I had to go back the way I came. ”

Zhou Ran wanted to say that if there is no way out here, he should look to the east, maybe there is an answer there. But seeing the current situation, it's better not to talk about it first.

Zhou Ran ate something casually, and began to ponder the stone wall at the end.

The color of the stone wall has not changed, it is still a whitish dark gray, and the texture seems to be very soft when you touch it. He picked it with his fingers, and he actually picked off a small piece, and it was easily rolled into powder, like foamed concrete for construction.

Grains of debris slowly drifted down, illuminated by the light, like dust in the sun.

Odd!

"Captain Yu, come and see."

Yu Lie heard Zhou Ran's call, put down the half-eaten nutritious meal in his hand, and asked after approaching, "What's wrong?" ”

"I'll do a magic trick for you."

"What?" Yu Lie looked dazed.

Zhou Ran picked out a small pinch of stones and showed him what he had found.

"So soft?"

Yu Lie felt incredible, and tried it as he spoke. As the stone chips slowly drifted down, his expression became more and more surprised.

"Isn't this a rock?" Yu Lie said suspiciously.

"It should be, but it's softer." Zhou Ran said and took two big steps to the side, "You try here again." ”

Yu Lie reached out to touch it, and immediately there was a feeling of hard texture, it was obvious that this was an ordinary rock.

"What does it mean that two different kinds of rocks, one soft and one hard, appear on the same rock wall?" Zhou Ran muttered to himself.

At this time, Yu Lie was in a daze and did not hear what Zhou Ran said clearly.

"Professor Zhou, what did you just say?"

Zhou Ran repeated it absentmindedly, and it seemed that he was also thinking about this problem.

"Maybe it's a coincidence......," Yu Lie said in a low voice.

"Captain Yu, borrow the dagger on your body for me." Zhou Ran stretched out his hand as he spoke, as if he hadn't heard what Yu Lie said.

Yu Lie pulled the dagger out of the dagger sleeve on his calf and handed it to him.

"Good knives!" Zhou Ran praised.

"Military daggers, more practical."

When he saw what Zhou Ran was doing with the dagger, Yu Lie showed a distressed expression.

"Professor Zhou, you can use the back of the knife to ...... in reverse," he hurriedly reminded.

Zhou Ran flipped the dagger and scraped it on the stone wall, Yu Lie called two people to come over to help, but he refused.

Before the important things are determined, only trust your own judgment, which is Zhou Ran's consistent practice.

At this time, Yu Lie already understood what Zhou Ran was going to do.

After about two minutes, Zhou Ran had already drawn a dividing line between soft and hard rocks, soft in the middle and both sides. Moreover, the size of the soft rock in the middle is about two meters wide, and the height is uncertain, because Zhou Ran can only reach the position of about one meter eight.

"Come here," Yu Lie shouted, "Zhang Qiang!" ”

Then, a tall, thin young man walked up to him, took the dagger in Zhou Ran's hand and was about to start scraping the stone wall.

"Bring it!" Yu Lie snatched the dagger, took out a small piece of cloth and wiped it carefully, "Use your own." ”

"Captain, you're too stingy." Zhang Qiang smiled and drew his dagger.

"Captain Yu, it seems that your dagger is not simple." Zhou Ran said half-jokingly.

"That is, our captain's dagger is so precious that most people are not allowed to touch it." Lu Shun said with a smile.

"Mouthy."

Zhou Ran was a little reluctant and said, "Yo, Captain Yu, that's embarrassing, if you know, you don't need it to scrape." ”

Yu Lie smiled awkwardly and said, "It's okay, don't listen to their nonsense." ”

While a few people were talking, Zhang Qiang suddenly said: "I can't reach it either!" ”

Yu Lie visually measured that it was about two meters high, and took out the ranging instrument and measured it, two meters and one two.

Zhou Ran looked at the dividing line on the stone wall, and suddenly had an idea in his heart.

"Don't you think this looks like something?"

"The door." Lu Shun said.

"That's right," Zhou Ran said, "if nothing else, this should be a door." ”

Yu Lie nodded and said, "This statement is very reasonable, but how to open it?" ”

Zhou Ran looked at the "door", then looked at the sapper shovel on Zhang Qiang's back, and then stopped his gaze on Lie's face.

Yu Lie showed an embarrassed expression on his face, he dragged Zhou Ran aside, and whispered, "Professor Zhou, I understand what you mean, but our first task is to save people, and there will obviously be no one here." I think we should go back the way we came......"

"Captain Yu, you're right," Zhou Ran didn't deny his statement, "However, it is also our task to find out the truth here, and he is as important as saving people." No, it's more important than saving people! ”

Seeing Zhou Ran's firm eyes, Yu Lie once again chose to compromise.

"Listen to the rescue team, dig me according to the place within the dividing line on the stone wall!"

"Thank you!" Zhou Ran whispered.

"I want to figure it out too."

……

After the rescue team's vigorous excavation, a hole 50 centimeters deep was dug into the stone wall in a short time.

When, when......

"Captain, in the end, I can't dig it."

Yu Lie and Zhou Ran took a closer look, it was a dark black rock formation, and they poked it with a sapper shovel, and there was no scum at all.

Zhou Ran pushed the black rock formation hard, not moving.

He couldn't help but think, "What's wrong?" ”

He looked down and pondered, imagining all the information related to the door, and at that moment, he suddenly thought of his laboratory.

In order to ensure safety and the rigor of the experiment, all laboratories of the Institute of Ecology are equipped with advanced smart door locks, which require fingerprints and card swiping to enter and exit, and can be operated through the control screen next to the door.

Thinking of this, Zhou Ran hurriedly walked to the right side of the "door", and began to touch the position of the laboratory control screen in his memory, but all he could touch was cold and hard rock.

"Come, that lad." Zhou Ran shouted at Zhang Qiang, "It's probably this area, see if you can poke it." ”

Zhang Qiang immediately took action, until he found a soft rock in a position that was almost out of reach above his head.

"Professor Zhou, you are really a god!" Zhang Qiang said admiringly, "However, I can only get here." ”

"Two more people, stacked arhats." Yu Lie said.

After a while, a small crater sixty centimeters square appeared.

"What's inside?" Zhou Ran asked.

"What is there and there is, just ......"

"What?"

"It looks like there's a bulge in the middle."

"Press it down." Zhou Ran said without hesitation.

"Pressing the ...... without moving"

"Hard!"

"Still ......"

didn't wait for Zhang Qiang to finish speaking, only to hear a loud "boom", which startled everyone to retreat in a hurry.

Then, the "door" slowly rose, and when it reached the top, a black hole appeared in front of me.

When everyone was in shock, Zhou Ran's flashlight shone straight in, and then he walked in. Yu Lie was just about to stop drinking, but it was too late.

"Don't move, wait outside!" With that, he hurried in.

"Professor Zhou, are you alright?"

Zhou Ran didn't reply, but followed the light of the flashlight and scanned everything in front of him.

Yu Lie was also stunned by the scene in front of him!

It's like a huge room, it's not empty, it's filled with a lot of things. Although each item is covered with a layer of gray, the same color as the stone walls, some of them can be roughly discerned according to the outline.

Irregular tables, chairs, worktops, these are as tall as a person. There was something like a handle next to the console, and he wasn't sure.

In addition, there is a large screen, countless small screens, spiral staircases......

In the middle of the room, a raised platform stands out.

It is about two meters tall and has a round pillar about one meter high that holds an oval-shaped disk. However, the disc seemed to be empty, as if something was missing.

The room has two floors, the ceiling is about ten meters high, and the spiral staircase that connects the two floors is the spiral staircase.

Once it is certain that it is safe, others are allowed in. Of course, they were also amazed by what they saw.

Zhou Ran was extremely excited, and did not hesitate to turn on his video equipment and record the scene in front of him.

In addition, he was sure that there was only one entrance and exit to the room, and that was the doorway they entered.

Zhou Ran had a hunch that this place might have a lot to do with the "earthquake", and if he figured out everything here, maybe the truth would come out.

"Captain Yu, I think this place is very strange, and I want the survey team to take a good look." Zhou Ran said, "What do you think? ”

For such a statement, Yu Lie naturally couldn't object, this was their task.

"How do you want us to cooperate?"

"I found out that there was only the door we came in, which was obviously not normal, so I ......"

Yu Lie understood, so he said, "Well, I also found out, and this matter will be handed over to us." ”

The two gathered their own team members, assigned tasks, and went their own way.

Zhou Ran was very interested in the disc held by the column, and he couldn't see the situation in the disc below, so he climbed up the spiral staircase to the second floor and took a close-up photo.

When he zoomed in on the photo, he could clearly see the structure of the disc, which was very simple, with only a strange shape.

Zhou Ran is not easy to describe, it is a bracket similar to a lotus pod, rooted in a disc. Although the "lotus pod" is also covered with a layer of gray rock formation, the holes on it are clearly visible.
