In the process of moving forward, each passage was marked with a serial number, and now it has been marked with 219, which means that 219 stone chambers have been searched, and the average time for each is four minutes. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

At this time, it was found that the rock walls of the stone chamber behind were all basalt, and the internal space and plane area were much larger than those seen at the beginning, and the thickness of the water on the ground increased slightly, and it remained at about three centimeters.

Apart from that, no other discoveries have been made, and there is no clue as to the hidden danger, or unknown creatures.

Chen Feng drew a road map on the holographic screen as he walked, but it was not a route in the strict sense, but a map of the shape of the stone chambers he passed by, one by one, according to their actual orientation, hoping to write down the way back through this method.

Using the flow of water as a guide is only useful for going to the source, because there is only one source, and if you follow the flow of water, you may enter other forks and deviate more and more from the way back.

It was 11 o'clock in the evening when the serial number of the 220th stone chamber was marked, and the survey has taken nearly 15 hours so far.

Xu Mengyi saw that the mark was exactly an integer, so he stopped the team and proposed that this be the end of the day.

Chen Feng also felt that his physical strength was almost exhausted, and agreed with him, took a few large stones from the passage that had just been opened to make benches, and then went to the Silent Whisperer to get some food, and used dinner with Xu Mengyi on the spot.

Xu Mengyi gnawed on the cold can and said, "It would be nice if Mi Xue was here, with her fire element, she could eat some hot rice." ”

Chen Feng, who was serious, only said, "It's good to have something to eat", and casually mobilized the holographic screen to send Wang Yi where he was at this time.

Wang Yi in the communication said: "I know, I have a holographic computer connected to you remotely, I can always pay attention to your vital signs, if there is an abnormality when you are resting, I will wake you up in time, of course, it is not necessarily safe, you should pay more attention to yourself." ”

"Can you mention something useful, Wang Dashao, how should I pay attention when I fall asleep." Xu Mengyi accosted.

"Well, there's another way that doesn't work, you empty the stagnant water in the stone chamber where you rest, and block all the passages."

Xu Mengyi said listlessly: "Don't make trouble, you don't think anything about it when you're leisurely there, we're about to fall apart." ”

"I think I can try."

Chen Feng solemnly pointed out that the Silent Whisperers still have a lot of physical strength, and it should not be much of a problem for them to clear the stagnant water here, the key is to block the passage into the water.

After dinner, Chen Feng began to arrange for the Silent Whisperers to block the passage into the water, and found that the actual situation was far from being as easy as imagined, and the high density of basalt could not prevent the penetration of this clear water.

Xu Mengyi had an indifferent smile on her face, as if she had expected this situation.

Maybe you don't need to think about it, because the entrance of the passage was originally blocked by basalt, and in that case there was clear water seeping through, not to mention the wall that was re-added later.

Xu Mengyi didn't have hope to stop the influx of clear water, and advised Chen Feng not to waste that effort, and instead arranged for the Silent Whisperer to build a bed with rocks to ensure that everyone would not soak in the water when they were resting.

The night passed peacefully, so that everyone could not help but wonder if there was no danger here, and wonder if what happened yesterday could be some kind of physical exhaustion.

Xu Mengyi asked Chen Feng, "How is it?" Are they all there? ”

"It's all here, have something to eat at the event, and continue on the road later."

"Don't worry, I have an idea......" Xu Mengyi looked at the surveillance footage and found that the markings on the entrance of the passage were still there, and he didn't say anything more.

Chen Feng asked, "What? ”

"It's nothing, I was just wondering if I should go back a few rooms and see what happened to the number we left, it doesn't seem like there's any need for that."

Chen Feng called up his holographic screen, checked the monitoring screen on it, and understood that they had encountered a situation where the mark was erased, but it seemed that they had not encountered it again at this time, and casually put forward a hypothesis, saying that it would be because the monitoring was interfered with.

Xu Mengyi listened to the listener's intention, and then proposed to go back a few rooms to see if the nearby mark was still there.

Chen Feng thought that he couldn't walk a few steps, and agreed: "Let's go." ”

Xu Mengyi turned around and walked towards the passage on the north side, and hurriedly looked at the rock wall on the right side of the passage when he stepped through the passage.

Chen Feng saw that he was stunned and had a bad intuition, and when he looked at his line of sight, he didn't see the "219" mark that should be there.

Although the rock wall is dark brown, the oil is darker, and if the marking is still there, you won't see anything, and there is no discolored basalt wall.

Xu Mengyi touched the place where the mark should be, and then put his finger on the end of his nose.

Chen Feng knew what the situation was when he saw his expression, looked around at the scene, and asked, "Is it that we are in the wrong place?" ”

"We can't both remember wrong, not to mention that there are three passages in the 220 stone room, the one on the south side is the water inlet, definitely not, the one on the east side is completely unimpressive, so it can only be here."

After Xu Mengyi deduced, he couldn't help muttering to himself, guessing that something was playing hide and seek.

Chen Feng encountered this kind of thing for the first time, in addition to being surprised and puzzled, he wanted to find out the reason for the disappearance of the marker, so he carefully observed the surroundings, and then called up the map he drew yesterday on the holographic screen, and proposed to go to the next stone room when he came.

Xu Mengyi still had some impressions of the next stone room, knowing that it was the passage on the west side, and seeing that the signs on Chen Feng's map were correct, he thought that he might not get lost again this time, so he deliberately asked him to lead the way, so as to determine whether the route on the map was correct.

Although there was no mark in the second stone room that arrived, everyone had a familiar feeling about it, and then went to the third room on the way back, and there was still no sign of the mark.

Xu Mengyi looked at the familiar stone room and said: "It's basically confirmed, the marks we left not only erased, but also deliberately left those before the monitoring, it is estimated that that thing must be a high-IQ thing." ”

"What is its purpose? Get rid of us? ”

"Or else?"

Xu Meng recalled the ghostly personality and added, "Or just toss us as prey and provide it with consciousness activity." ”

Chen Feng nodded in agreement, and then called the silent whisperers who were on duty yesterday and asked them if they sensed any abnormalities around them.

They were not asked if they had sensed the ghost, and if they did, they would have moved and reported it, and they didn't mention the situation, so they were only asked if they had noticed anything abnormal, even if it was subtle. (To be continued.) )
