After Lin Wu went down, he found that this was not only a confined space, but also a very strange and wrong confined space.

Unlike the passage of the cave they had passed through before, it was an apparently man-made stone chamber, square, with unknown materials on the walls, reflecting a cold light in the light of a flashlight.

Even the ground under your feet has become a stone brick that is of extraordinary value at first glance.

Not to mention Lin Wu, Kate, Zhang Shan and Xiao Yang were all stunned.

Bo Yuting, who finally came down, looked at it and was surprised: "What kind of place is this?" ”

If it is placed in normal times, it is certainly not too unusual to see such a stone chamber. But the problem is that they are now under the mines, and they should have seen the same kind of caves as before.

It's weird to think that this kind of place is found in the underground where ore is mined.

What's more, it doesn't appear on the map at all.

Several people looked at Kate.

Even Xiao Yang and Zhang Shan, who had been following him, asked blankly: "Boss, ...... under our mine?" Is there such a place? ”

Kate looked around carefully, looking thoughtful, and confused, and said uncertainly, "I don't know." The people in the restricted area didn't tell me before I came. At the time of previous mining, the people of the mine had not found such a place. ”

Come to think of it, if it weren't for the road that Anna and the others accidentally discovered, maybe no one would have discovered it here.

Kate's eyes flashed slightly, and she quickly said, "Since you're already here, don't worry about it so much, let's continue to go first." ”

He looked behind him, where there was an exit, and it looked like a stone path outside.

"There's no way back anyway."

After he finished speaking, he took the lead and walked briskly towards the exit.

Xiao Yang and Zhang Shan followed in a daze.

Lin Wu and Bo Yuting exchanged glances and walked over.

The outside is really a stone road, and it is open to the left and right.

"This ...... Boss, which way do we go? Xiao Yang asked hesitantly.

Kate didn't know either, he asked Lin Wu directly: "Miss Lin, which way should you go in your intuition?" ”

Lin Wu didn't say anything: "I'm not familiar with this place, and I don't know which side is safe." ”

Kate Wen said: "It's okay, I believe Miss Lin, Miss Lin tell me which way you think you can go." ”

Lin Wu really didn't know where Kate trusted her.

She raised her hand and touched her left shoulder, and the tattoo did not react in the slightest, indicating that there was no danger at the moment, and it was okay to go either way. She casually pointed to her left.

Kate had no doubt and walked straight over there.

Along the way, Xiao Yang and Zhang Shan also trusted Lin Wu's reliability and followed without thinking.

And Lin Wu and Bo Yuting walked side by side at the back.

The five of them all walked and looked at the strange stone path inquiringly.

The stone path is not narrow, two or three people can walk together, and there is still room for free, so the five of them are very close, so that if there is an accident, they can't react, and the people around can also help.

With previous experience, they also walked very carefully, so as not to accidentally run into any unexpected mechanism.

As she walked, Kate suddenly said, "I don't know what to say about our luck, we may have entered a dungeon that is not small in scale." ”

"The Underground Tomb?"

The four of them looked at him in unison.

Kate snorted and said calmly: "The front is unknown, I will tell you all the information I may be able to see now, have a number of each other, be vigilant." ”

"Looking at the way the stone path is built, it looks like the blue bricks and stones that I have known of that were specially used to build tombs. If my guess is correct, then we are currently at the outermost part of this underground tomb, and we should be able to reach the outer tomb if we go forward. Looking at the surface texture and feel of the stone bricks, it should have been around for many years. The owner who originally built it definitely spent a lot of financial, material and manpower to dig through the ground and carry out the corresponding engineering work. ”

Hearing this, Bo Yuting's gaze became more and more strange and elegant.

"What else do you know?"

"It's just a former interest."

Kate didn't want to say more, and continued: "The spider people and flying insects we encountered outside earlier should have been raised by the owner who built this place to guard this place and prevent outsiders from entering. And the road that Anna discovered should have been deliberately hidden, so basically no one found it before. ”

Lin Wu asked inexplicably: "The forbidden domain has occupied this place for several years, haven't you ever found that there is a suspiciously large building hidden here?" ”

This question doesn't need Kate to answer, Bo Yuting also knows the answer.

He said, "Judging by the speed and time we've been crawling down that passage just now, it's at an incredible depth. Normally, miners don't mine this deep. ”

"That's right." Kai nodded, "Those miners are mining at known safe depths. If they don't dig deeper, it's hard for them to spot. ”

Lin Wu couldn't help but think of one thing: "So the black fog and the monsters with hairy faces that inexplicably appeared in the mine are also guarding here?" In the past, when your people had a mining disaster here, I think it was all mining new places, right? Did they mine where they shouldn't have been found, and be killed by something guarded? ”

"Very likely."

Kate said solemnly.

Bo Yuting also thought of one thing: "When I studied those black fogs, I found that they were originally contained in some kind of ore, and they were released by reacting with something. Looking at it now, the ore with the black mist should be above here, and someone or something entered by mistake, triggering a certain protective mechanism for refusing to enter the outside world, and then releasing the black mist? ”

"If that's the case......"

A guess appeared in Lin Wu's mind, and he said in surprise: "Is it Cheng Man?" He found it through those furry monsters, and then he stumbled into the black mist? ”

Glancing at each other, Bo Yuting understood in seconds: "Cheng Man is more likely to enter here by mistake like us?" ”

If all the guesses are correct, then this is the most reasonable development possibility at the moment.

Correspondingly, it means that Cheng Man is safe, at least he didn't die in the hands of the black fog and those monsters with long hairy faces.

Kate looked at them, "Congratulations to you, your friend has a very good chance of surviving, and he should be waiting for you to find him somewhere here." ”

So far, this should be the only piece of good news.

But several people were all the same, and they were not happy at all.

Because if they're right, they can also come up with a very bad news - there has to be something or a secret here that requires so much effort on the part of the people who built it? The more you don't want people to come in and find out, the more dangerous it becomes.

Xiao Yang sighed sentimentally: "Just those outside, we have been." It's tricky, so what's going to happen here? You're not going to put your life here, are you? ”

Although he ignored life and death, it does not mean that he is willing to die in such an unknown place.

"No!"

Lin Wu, Bo Yuting and Kate said in unison.

The three of them looked at each other, and then quickly separated.

Lin Wu said calmly: "There is no place to leave me." Even if we can't get out, people will come looking for us. ”

Xiao Yang and Zhang Shan wanted to talk and stopped, the question was whether they could survive that time?

The silence in the stone path became more and more clear, as if even the sound of the heartbeat was clear, and the five of them continued to move forward with their own thoughts.

But the stone path was much longer than they had imagined, and they came to the end, and there were corners, and they went along the way, and turned several times, and suddenly they came to the end.

There are no doors.

"Why is there no exit?" Xiao Yang and Zhang Shan were a little panicked, "We won't be very unlucky and enter a dead end, right?" ”

Lin Wu twisted his eyebrows and said, "Don't make a conclusion first, go, and then go back and look carefully, maybe there is some hidden mechanism?" The secret passage that came in earlier was not opened through a very secret mechanism. Before we found the mechanism, we thought we were going to die near the entrance of the cave. ”

A few people turned back and looked carefully, this time walking very slowly, groping as they went. However, until they walked back to the place where the secret passage had come from, they still found nothing.

They simply moved on to the other way.

But I didn't think about it, and the other end was also a dead end!
