Unlike the mine passages they had passed through before, this was a stone chamber that was obviously man-made. It was square and the walls were made of unknown material, reflecting a cold light under the light of the flashlight.

Even the ground beneath your feet has become stone bricks that are obviously of extraordinary value.

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

Bo Yuting, who came down last, took a closer look and was also surprised: "Where is this place?"

Under normal circumstances, it would not be unusual to see such a stone chamber. But the problem was that they were now under the mine, and the mines they saw should be the same as before.

It seems strange that such a place appears in the underground where ore is mined.

What's more, it has never appeared on the map at all.

So everyone looked at Kate.

Xiao Yang and Zhang Shan, who had been following him, were both confused: "Boss, there is actually such a place under our mine?"

Kate looked around carefully, her expression thoughtful, and she spoke in confusion: "I don't know. The people in the restricted area didn't tell me before I came here. When they were mining before, the people in the mine didn't find such a place either."

I think, if Anna and others hadn’t discovered the road by accident, perhaps no one would have ever discovered this place.

Kate's eyes flickered, and she quickly said, "Since we're already here, don't worry about it anymore and just keep going."

He looked behind him. There was an exit there and the outside seemed to be all stone paths.

"There's no way back anyway."

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

Xiao Yang and Zhang Shan followed in a daze.

Lin Wu and Bo Yuting exchanged glances and walked over.

There was indeed a stone path outside, leading to both sides.

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

Kate didn't know either, so he asked Lin Wu directly: "Ms. Lin, which way do you think you should go?"

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

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

Lin Wu really didn't know where Kate got the trust from.

She raised her hand and touched her left shoulder. The tattoo didn't react at all, which meant that there was no danger at the moment and she could go either way. She pointed to the left.

Kate had no doubts and headed straight over there.

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

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

The five of them walked and looked at the unfamiliar stone path in inquiry.

The stone path was not narrow, and could easily accommodate two or three people walking together with some space left, so the five of them were very close to each other. This way, if something unexpected happened and they couldn't react in time, the people around them could lend a hand.

With previous experience, they walked very carefully to avoid accidentally encountering any unexpected traps.

As they walked, Kate suddenly said, "I don't know how to describe our luck. We may have entered a rather large underground tomb."

"Underground tomb?"

The four of them looked at him.

Kate hummed, "The front is all unknown. I will tell you all the information I can find out now, so that you can have an idea."

"The construction style of the stone path is very similar to the blue bricks and stones that I know of that are used to build tombs. If my guess is correct, we are currently at the outermost edge of this underground tomb. If we walk forward, we should be able to reach the outer tomb chamber. Judging from the surface texture and touch of the stone bricks, they should have existed for many years. The original owner who built it must have spent a lot of financial, material and human resources to dig through the underground construction and carry out the corresponding engineering work."

After hearing this, Bo Yuting looked at Kate with an even more strange look.

"Just a hobby."

Kate didn't want to say more, and continued: "The spiders and flying insects we encountered outside before should be raised by the owner who built this place to guard this place and prevent outsiders from entering. And the road Anna found should also be intentionally hidden by humans, so basically no one has discovered it before."

Lin Wu was puzzled: "The Forbidden Domain has occupied this place for several years. Hasn't it discovered that there is a suspected large building hidden here?"

Kate didn't need to answer this question, Bo Yuting already knew the answer.

He said, "Based on the speed and time we spent crawling down the tunnel just now, this is at an incredible depth. Normally, miners don't mine this deep."

"That's right." Kate nodded. "Those miners are mining at a known safe depth. If they don't continue to dig deeper, it will be difficult for them to find you."

Lin Wu couldn't help but think of one thing: "So the black fog and the monsters with hairy human faces that appeared inexplicably in the mine are also guarding this place? I remember that the mining accidents that your people had here in the past seemed to be mining in new places, right? Did they mine in a place that they shouldn't have discovered and were killed by the things guarding it?"

"Very likely."

Kate said solemnly.

Bo Yuting also thought of something: "When I studied the black mist, I found that it was originally contained in a certain ore, and was released after reacting with something. Now it seems that the ore with the black mist should be above here. Someone or something accidentally entered and triggered a certain protective mechanism here that refuses outsiders from entering, which released the black mist?"

"If that's the case..."

A guess emerged in Lin Wu's mind, and he asked in surprise: "Is it Cheng Man? Did he find this place through those hairy monsters with human faces, and then accidentally created the black fog?"

After exchanging a glance, Bo Yuting understood immediately: "It is more likely that Cheng Man entered here by mistake like us?"

If all the guesses are correct, then this is the most reasonable possible development at present.

Correspondingly, it also means that Cheng Man is safe, at least he did not die at the hands of the black fog and those hairy monsters with human faces.

Kate looked at them and said, "Congratulations, both of you. There's a very good chance that your friend is alive. He should be waiting for you to find him somewhere here."

This is probably the only good news so far.

But they all felt the same: they were not happy at all.

Because if what they thought was right, it could also lead to a very bad news - there must be something or a secret here, which required the people who built it to spend so much effort to guard it? The more they don't want people to come in and find it, the more dangerous it is.

Xiao Yang sighed sentimentally, "Just those things outside are already very difficult for us, so what will we encounter in here? We won't lose our lives here, will we?"

Although he doesn't care about life and death, it doesn't mean he is willing to die in such an unclear place.

"Won't!"

Lin Wu, Bo Yuting and Kate said in unison.

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

Lin Wu said calmly: "There is no place for me to stay. Even if we can't get out, someone will come to find us."

Xiao Yang and Zhang Shan were hesitant to talk, the question was, can they hold on until then?

The stone path became increasingly silent, as if even the sound of one's heartbeat could be heard clearly. The five people continued to move forward, each with their own thoughts.

But this stone path was much longer than they had imagined. When they reached the end, there was a corner. They followed it and turned several times before suddenly reaching the end.

There is no door.

"Why is there no exit?" Xiao Yang and Zhang Shan were a little panicked. "Are we just unlucky and have we reached a dead end?"

Lin Wu frowned and said, "Don't jump to conclusions yet. Let's go back and look carefully. Maybe there is some hidden mechanism. The secret passage we came in earlier was opened by a very secret mechanism. Before we found the mechanism, we thought we would die near the cave entrance."

The few of them turned back and searched carefully, this time walking very slowly, groping as they went. However, until they returned to the exit of the secret passage, they still found nothing.

They simply continued on another route.

But I didn't expect that the other end was also a dead end! (End of this chapter)
