The Whisperers on duty last night said that they did not find anything unusual, so they speculated that the creatures approaching Room 219 had used some method to hide their elemental aura, and their combat power was likely to be much higher than that of the Whisperers.

"Well, it's completely dark and clear, maybe that guy is watching us somewhere right now, and he can see clearly what we say and do."

Xu Mengyi then typed down a text on his holographic computer, asking Chen Feng if there was a way to change this situation, and then half-covered the text with his hand and showed it to Chen Feng, hoping that only he could see it.

Chen Feng shook his head with a heavy face, pushed away the holographic screen and said, "It's probably useless to do this, if that thing is really monitoring us all the time, it should be able to see it." ”

"That's not necessarily, otherwise everything we say will be heard by that guy, and there's no way to do it." Xu Mengyi turned to the monitor inside the helmet and pointed at his helmet.

Chen Feng instantly understood, pulled off the mask on his armor helmet, and then set up a sound shield inside the armor to prevent the voice from reaching the outside, and then used internal communication to have a conversation.

"It should be fine now." Xu Mengyi said.

"To sum up, look for clues, if there is really something moving here, it will definitely leave traces."

"The problem is that nothing is found, you wait first."

Xu Mengyi stretched out his hand and pulled the mask on his helmet, instructed the silent whisperer beside him to give them a task to search carefully, and then pulled the mask and communicated with Chen Feng: "Okay, continue." ”

Chen Feng analyzed: "What can be determined at the moment is that the thing has erased the mark on the entrance of the passage, and it has launched an attack on us once, so it can be concluded that it is hostile to us, or it is to satisfy its war as food." ”

"Hasn't this been analyzed a long time ago?"

"Rational thinking, there's nothing else about that thing other than what I just said, right?"

Xu Mengyi thought about it briefly and said, "Yes, then what do you say we should do now, can we set a trap or something, and when it is trapped, we will kill it." ”

"What trap? We don't even know what that thing is now, and what traps can we set up? ”

Xu Mengyi pondered the conditions of the team and said: "How about the Buzhi ambush, on the way forward, let some of the silent whisperers possess themselves in the rock wall and secretly observe the movements in the stone room. ”

Chen Feng looked around at the situation around him and said, "What if that thing is right next to us?" ”

"Then it can't be helped, but I don't think so, otherwise how would it erase the mark on the entrance of the passage in the distance."

Chen Feng closed his eyes and pondered: "That's the number of them. ”

"Hey......" Xu Mengyi sighed.

"Maybe ......," Chen Feng hesitated, "It's not that there is no way at all." ”

Xu Mengyi was curious: "What? ”

"The second search team, let Wang Yi send another team down, and those people will walk through us again, and then keep a certain distance from us, there may be discoveries."

"That's it."

Xu Mengyi was not hopeful about this, and added that if that thing could not be found around him, let alone those who observed from a distance.

All the ways that can be thought of have been thought of, and those silent whisperers who searched for clues have not gained anything, and there is nothing they can do about the unknown creatures hidden in the shadows.

After some discussion, it was decided to continue the exploration of the stone chamber first, and stay vigilant on the road to see if the thing would show its feet.

Everyone began to get back on the road, still marking serial numbers on the entrance of the passage along the way, not to make it easier to find the way back, but to note down how many stone chambers they had explored.

For the way back, there is also a map drawn by Chen Feng to guide him, and the stone chambers he walked through are always drawn on the road.

Xu Mengyi no longer moved forward, and began to use a holographic computer to collect the parameters of various stone chambers, including the volume of the stone chamber, water level, internal oxygen content, and so on.

It was not until lunch at noon that 70 stone chambers were newly explored, and each one took an average of five minutes, which was longer than yesterday's, probably because the volume of the stone chambers here had also increased, but Chen Feng said in the casual chat that today's physical exertion rate was much faster than yesterday.

Xu Mengyi sat at the mouth of the passage marked with the number "290" and used food, glanced at the stone chambers on both sides of the passage, which were the size of a football field, and couldn't help but ask Chen Feng who was squatting next to him: "Dafeng, you said that the underground space in this place is so big, why haven't you seen the landslide, is it unscientific?" ”

"Hmm."

Xu Mengyi put down the unused cans in his hand, re-read the geological documents about this place on the holographic screen, and found no information related to the underground cavities, and continued: "This place shouldn't have appeared recently, right?" ”

"Hmm."

"Ghost-made?"

"Hmm."

Xu Mengyi heard that he was just perfunctory, looked sideways at what he was doing, and found that he was still drawing, so he stepped forward and said, "Haven't finished painting yet?" ”

"What?"

"I said how can this room be painted so slowly?"

"It's not." Chen Feng set out to enlarge the holographic screen and pointed to the oval circles on it, one by one.

Xu Mengyi got up in surprise and said, "Oh my God." ”

Chen Feng glanced at the line he was taking and said, "We are now going in circles, like mosquito coils, from the inner circle to the outer circle, layer by layer. ”

"And the depth." Xu Mengyi looked at the stone room parameters arranged on his holographic screen and said, "We have been going down, and now the vertical height from Wang Yi and their side is 3.2 kilometers. ”

Chen Feng pondered: "Circle, descent, basalt. ”

Xu Mengyi then combined these words, looked at the center of the road map on Chen Feng's holographic screen, and wondered: "Shouldn't we be turning around the edge of the underground fire?" ”

Chen Feng got up and patted the basalt beside him, and said: "We walked at least 30 kilometers today, plus the dozens of basalt chambers we walked yesterday, the total basalt distance is at least 40 to 50 kilometers, according to the distance we have divided by the number of rings, and then divided by pi, the diameter of the volcano on this plane may be 4 to 6 kilometers now, so we should be on the top of the mountain." ”

"And then?"

Chen Feng looked at the road map drawn and said: "If the key to this place is this volcano, then the source of Qingshui may be at the foot of the volcano, and we may be able to figure out the problem when we get to the foot of the mountain." ”

"And how far do we have to go?"

"It's hard to say, I don't know the volume of this volcano, I can't calculate it."

Xu Mengyi didn't have much patience to go any further, so he drew a straight line on Chen Feng's route map. (To be continued.) )
