Since Chen Jian has made the decision, everyone will naturally not have any objections.

What's more, Chen Jian had already considered it quite thoroughly. He entered again and entered the first stone door. The primary purpose was to test out that they entered the second stone door, took a circle, and came out from the second stone door. Is it a coincidence or a maze mechanism, even if it was designed like this.

Because this situation is somewhat different from previous judgments, their judgment before entering for the first time is very likely to be trapped inside, rather than being able to get out of it and return to the origin.

Chen Jian was the first to walk towards the first stone door, and the others followed Chen Jian and prepared to enter the first stone door on the left.

Xiao Yurou did not move, but frowned and stood there because Xiao Yurou always felt something was wrong.

When she saw Chen Jian and the others walking to the stone gate, Xiao Yurou finally thought about why she felt something was wrong and immediately shouted: "Wait a minute!"

Chen Jian and the others had not entered the stone gate at all. When they heard Xiao Yurou's words, they immediately looked at Xiao Yurou.

Xiao Yurou said, "I always felt something was wrong. I just thought about why something was wrong. We had to enter the passage inside the second stone door again and checked. I made marks all the way. There were marks at the first turn, but we came back and still came out of the second stone door. What about the marks? Why didn't we see the marks I made?"

Hearing Xiao Yurou's words, Chen Jian nodded, walked back quickly, and said, "I'll go in and check it out. Anyway, it's not far from you to enter, which is the corner where you mark it."

Chen Jian walked back quickly and prepared to enter the passage inside the second stone door with Xiao Yurou again for inspection.

At this time, Wang Fugui quickly chased after him, tied the other end of the rope to Chen Jian and Xiao Yurou's waists, and said, "No matter what, it is confirmed that it is a maze mechanism inside, but don't say it, it's safe, you go in and check the marks and come back immediately."

Chen Jian and Xiao Yurou nodded, took the rope and entered the passage inside the second stone door again. After walking a short distance, they reached the corner.

Xiao Yurou pointed to the corner of the wall and said, "My marks are made here, they are made along the corner of the wall. The marks are also turned around. It is very obvious, but now there is no more!"

Chen Jian nodded and said, "The walls here are covered with black light-absorbing materials, which may be caused by the fluorescent spray failure."

While Chen Jian was talking, he wiped the black light-absorbing materials on the wall with his hands. Wang Fugui had wiped these black light-absorbing materials with his hands, and there was nothing to do, so there was no need to worry about danger.

Chen Jian wiped it a lot, and the palms of his hands were hot. Under Xiao Yurou's light, it was clearly visible that Chen Jian's palms were stained with these black light-absorbing materials.

However, the black light-absorbing material that Chen Jian wiped was not completely wiped off, and there are still some that cannot be judged as such black light-absorbing material!

"It's hard to wipe." Chen Jian shook his head slowly and said, "Go out first."

After Chen Jian and Xiao Yurou retreated, they said, "The marks we made have disappeared. It seems that if you want to leave a mark that will not disappear on the wall, you must wipe off all the absorbent materials. However, I have tried it just now. This black absorbent material is difficult to wipe, and I don't know how much it has been applied."

"We can mark it in a way of destruction." Xiao Yurou said: "We used fluorescent spray to mark it before. Since it will disappear, we can mark it in a physical way."

There is no doubt that Xiao Yurou means using a dagger or other hard objects to leave marks on the walls, so that it will not disappear, because no matter how thick the black absorbent material is applied to the walls, it can be penetrated by hard and sharp objects, so that the marks will be made directly on the mountain walls, so naturally there is no need to worry about the marks disappearing.

Xiao Yurou's proposal was obviously feasible, and everyone's eyes were focused on Chen Jian, and he wanted Chen Jian to make a decision.

Chen Jian pondered for a moment, shook his head slowly, and said, "No need!"

After saying this, Chen Jian smiled and said, "I'm not worried about destroying the walls. Although it also belongs to the category of cultural relics, carving marks on the mountain walls is nothing. This kind of passage cannot be taken out and can only exist in the same place. The reason I disagree is because I don't think it's meaningless."

"Why?" Xiao Yurou asked in confusion.

"This time, we chose to enter from the first stone door. The purpose is to determine whether we entered from the second stone door for the first time and then came out from the second stone door. The original intention of the maze array here was to go around in circles, or did we go back by chance to determine whether this maze array is trapped and makes people die of thirst and starve inside." Chen Jian said: "So, if we see the mark and change the direction, we will really go around in circles. We cannot choose to do it ourselves, and we will trap ourselves in it."

"Yes, if you are a little clever, you might be trapped in it, which will lead to us losing the correct analysis of this maze mechanism." Xuan Mingzi said.

Chen Jian nodded and said, "That's what it means. In addition, this maze mechanism must have the right way to go out, and there must be traces to follow. However, we have not found the correct way to crack it at present. When we find the right way to crack it, the marks we made before will be of no use!"

"Then let's go in again!" Xiao Yurou said immediately.

"Time still has to be calculated." Chen Jian said: "This time, you are only responsible for timing and no longer have to mark."

Hearing Chen Jian's words, Xiao Yurou nodded silently.

Seeing that everyone had nothing to say, Chen Jian waved his hand and said, "Let's go, go in through the first stone door!"

After Chen Jian said this, he led everyone into the passage behind the first stone door again. It was still the same as the first time he entered. Wang Fugui walked in the front, and Chen Jian and the others followed behind.

Wang Fugui did not take it lightly, and still kept exploring whether there was an organism all the way, as if it was the first time.

Time passed slowly, and Chen Jian asked while walking, "How long has it been."

"It's been one hour and sixteen minutes!" Xiao Yurou looked at the time and said.
