Chen Jian was opened when the third one, and when the other two stone doors were not opened, what he said to Wang Fugui was obviously to ask Wang Fugui to find the opening mechanism of the other two stone doors and open the remaining two stone doors.

Since there are three stone doors, you naturally have to open them all and compare them before you can make a choice and walk through the stone door.

At this time, everyone's eyes focused on Chen Jian again, and the meaning was obviously to ask Chen Jian to make an idea.

Behind the three stone doors are all passages of the same width as the stone door. Chen Jian didn't know which way to take, so he could only look at Wang Fugui.

After all, Wang Fugui is an expert in the mechanism technology. It is unknown whether there is a mechanism at the passage behind the stone gate. It depends on the opinions of Wang Fugui, the expert in the mechanism technology.

Wang Fugui looked at Chen Jian and said, "When the stone door was opened, when he looked at the stone door, he also looked at the passage behind it. It didn't look like there was a mechanism, but it's better to be careful, and then you can explore the way first!"

Chen Jian nodded silently and said, "It's still the same as before. We pull the rope and you can take good protection!"

After a pause, Chen Jian added: "Don't enter too deep, within ten meters!"

Behind the three stone doors are painted black passages, and you can't see how deep it is. However, from the ground illuminated close by, you can see that there are no downward steps, but extending all the way inside.

Therefore, Chen Jian would remind Wang Fugui not to go in too deep.

Wang Fugui nodded, checked the rope tied to his body, put on the cape again, nodded to everyone, and walked into the passage.

I don’t know what the passage behind these three stone doors is, and the range that can be illuminated is much smaller than the range that the light should have illuminated.

After Wang Fugui walked in, he soon couldn't see Wang Fugui.

Fortunately, Chen Jian and the others have night vision ability and can still see Wang Fugui. However, Chen Jian could clearly feel that his night vision ability and the dark passage behind the stone gate were also weakened.

Although Xiao Yurou and the others could not see Wang Fugui, they could hear the sound of knocking from time to time. This was the sound of Wang Fugui using engineer shovels to hit the ground, walls and other places in the passage. It could clearly hear the difference in the knocking sound, which made Xiao Yurou and the others relieved.

Because of the sound of knocking, it means that Wang Fugui is not in danger.

Not long after, the knocking sound disappeared at the middle of the hour. Everyone was nervously waiting for less than a minute, and Wang Fugui came out of it.

After Wang Fugui came out, he opened his right hand to everyone to show him.

I saw that Wang Fugui's right hand palm was pitch black.

"I don't know what this black drop is when the wall of the passage is applied." Wang Fugui said: "This black drop seems to have an impact on the forehead drop light."

"It may be some kind of light-absorbing material!" Alice said at this time.

Light-absorbing materials refer to light illuminating on things, without transmitting outside the lighting, nor mapping or large flares or reflections. Instead, after absorbing the light, part of the light is diffusely reflected, thereby maintaining a regular level of light and darkness.

The black thing in Wang Fugui's hand was not known, but it was applied to the mountain wall. The mountain wall was solid and could not have light and dark levels. Only the characteristics of the habitual materials were left, which were not transmitted, and did not produce mapping and large flares and reflections. The final effect was that the lighting effect of the lighting of the people in the passage was greatly reduced.

"Be careful in the future. If you encounter such a situation, you must try it with your hands. If it is poisonous, it will be troublesome." Chen Jian looked at Wang Fugui and reminded him.

"Uh, it's not stupid!" Wang Fugui smiled and said, "Look, I saw it first on the forehead cloak, and looked carefully to ensure safety before touching it with my hands."

Hearing Wang Fugui's words, Chen Jian looked at the place where Wang Fugui pointed, which was on his cloak.

Sure enough, there were a little black mark, very light, very light, and very small black marks.

Wang Fugui continued at this time: "The black drop on the forehead is so powerful. I wiped it hard with my hands. I wiped it a lot. I don't know what this black drop is, so it won't be easy to rub it off!"

"Safe inside the passage?" Chen Jian nodded and asked with a different question.

"Safety, nothing is there." Wang Fugui said: "The entire passage is made of manual drip marks. Uh, go and see the two door drip channels!"

Chen Jian nodded, held the rope and walked to the stone door in the middle. Wang Fugui continued to go in and investigate, Chen Jian and the others were waiting outside.

Not long after, Wang Fugui came out, nodded to Chen Jian and the others, and went to the third stone door again without saying anything.

This time, Wang Fugui came out faster.

After coming out, Wang Fugui said, "Look, the three channels are the same, but the three channels are not straight, they all have turns. The forehead is still going forward, and they all come back when they encounter turns!"

Hearing Wang Fugui's words, Chen Jian nodded, but said nothing.

At this moment, everyone's eyes looked at Chen Jian.

This is very obvious, and I am still waiting for Chen Jian to make a decision on which passage behind the stone door to go.

Chen Jian didn't say anything and was silent. Wang Fugui asked tentatively: "Or, go in and keep moving forward? Anyway, there is a rope, just hold the rope!"

Chen Jian slowly shook his head and said, "No need!"

After hearing Chen Jian's words, Wang Fugui stopped saying anything more.

Chen Jian pondered for a moment and said, "It's not very necessary to go in and investigate again. We entered from the stone gate and walked here. We had already experienced three mechanisms. These three mechanisms were still available for thousands of years. This shows that when these mechanisms were set up, the ancients considered the durability."

After a pause, Chen Jian continued: "Whether the stone door is opened, the chain board, or the steps we stepped on, these three mechanisms are set up in places without obstacles, or very wide and empty places. This single-fan stone door has been reduced a lot, and the passage is the same width and height as the stone door. If a mechanism is set up in this passage, someone dies in the mechanism, and the human bones after the death of the person may be stuck in such a small space, causing the mechanism to fail to operate."

"I'm afraid that one or two people can't get stuck?" Xiao Yurou said: "Although the stone gate is small, it's still very big."
