While Chen Jian and the others nodded slightly, their eyes showed admiration. There was no doubt that this was because Wang Fugui hit the ground and had already let them know that there was indeed an existence of an organ.

Wang Fugui stood on the last step, which means he stood at the entrance of this passage because the passage and the last step are connected.

At this time, Wang Fugui squatted down, and the length of his arm, plus the length of the engineer shovel, could undoubtedly extend to some distance inside the passage.

Although Wang Fugui's arm length and the length of the engineer shovel are nothing compared to the length of the entire passage, it is enough for Wang Fugui to hit the ground of the passage at a certain distance.

In the passage ground that Wang Fugui could touch with an engineer shovel, the sound that was reverberated when he hit the ground was the hollow echo, rather than the solid echo of the hard mountain stone ground.

Wang Fugui followed him down with a backpack. He put the supplies Xiao Yurou gave him in his backpack.

At this time, Wang Fugui opened his backpack and took out a bundle of ropes.

This rope is not thick, but it gives people a very strong feeling, because the color of the whole rope shows that the texture of the rope is obviously not an ordinary rope.

As for the texture of this rope, Chen Jian and the others naturally would not ask about it.

Wang Fugui untied the rope, tied the end of the engineer shovel, then threw the engineer shovel out, and threw it directly to the place where the passage was about to reach the end. Then he slowly pulled the rope back and listened to the sound of the engineer shovel rubbing on the ground.

When the whole rope was pulled back, Wang Fugui untied the engineer shovel and said, "Uh, go and explore the way!"

Wang Fugui spoke, lifted up his shirt and tied the rope to his waist.

Only then did Chen Jian notice that Wang Fugui had a waist that was about twenty centimeters wide, with a metal ring on it. Wang Fugui tied the rope to the metal ring at this time.

Moreover, Wang Fugui tied a knot quite strong.

Chen Jian took the rope handed over by Wang Fugui, but grabbed Wang Fugui and asked, "Are you sure?"

"Uh, I suspect this is a chain board!" Wang Fugui pointed to the ground of the passage and said, "I don't know that there are organs on the walls and top of the passage. It should be vague depending on the situation, but I will protect myself!"

Wang Fugui said, took out a folded blanket from his backpack and said, "This is a skin-skinned drop, it's strong and there's no problem!"

Since Wang Fugui can name the mechanism, or he should have made a judgment that the ground of the passage is a mechanism with a chain plate, it means that he must have an understanding of such mechanism.

Chen Jian let go of Wang Fugui's hand, and still reminded Wang Fugui to be careful. Then he watched Wang Fugui step down the steps and step on the ground of the passage.

At this time, Wang Fugui had already shaken open the folded and made of leather and tin.

After shaking open it, Chen Jian and the others realized that the blanket was actually a cloak, which Wang Fugui draped on his body, could perfectly protect him.

Wang Fugui only walked forward a few steps before stopping, then squatted down, and used the lower edge of the cloak to clean up the dust on the ground.

Thousands of years of dust, a thick layer, directly covered the original appearance of the ground.

After Wang Fugui cleared a piece of ground and there was no dust on it, he could clearly see that there was a gap on the ground. This gap was very thin and looked the same as when the two stone doors were closed. It can be said that it was tightly matched.

It can also be seen that a complete stone slab shape has a width of about one meter and a length of about two meters.

"I'm sure, it's a chain board mechanism!" Wang Fugui said: "This mechanism is a flip board mechanism. Three pieces are connected together. The stone slab in the middle is a single layer, and the two stone slabs in the front and back are double layers. The single stone slab in the middle is dripping together. Standing on the edge of the stone slab will not trigger. When you walk to the middle, the stone slab will be triggered. When the person falls, the stone slab will turn back and return to its original appearance!"

"Can a person recover from his original appearance when he falls? What is the source of power?" Xiao Yurou asked in confusion.

"There must be heavy objects under the stone slab to maintain balance. It should be a large stone that falls between the two ends and maintains balance. The two stone slabs in the front and back fall to one end, and three pieces are bitten together. Only when they walk to the middle will trigger. When the person falls down, there are no heavy objects on it. There are large stones falling down below. Maintaining balance will turn back to its original appearance." Wang Fugui said.

"How to crack this mechanism?" Chen Jian asked.

"Let's go the right way!" Wang Fugui said with a straightforward and natural look, "There must be a road without mechanism. Just walk along, just wait!"

After Wang Fugui said this, he walked forward while cleaning up and walked to the edge of the stone slab he was standing on. He did not step onto the second stone slab, but used an engineer shovel to press down hard on the stone slab in front of the stone slab next to it, which is the second stone slab!

As Wang Fugui pressed down hard, the three stone slabs were linked together. The place where the first stone slab and the second stone slab were connected tilted downwards, and the place where the second stone slab and the first stone slab were connected also sagged, which formed a downward inverted triangle that would directly sink people.

As for the third stone slab, the second stone slab connected to the first stone slab is sunken, the second stone slab connected to the third stone slab is upturned, which leads to the second stone slab connecting to the third stone slab, which shows upward and forms a high triangle.

Immediately afterwards, the three stone slabs maintained balance because they were hung with large stones under them, and returned to their original state.

Chen Jian and the others were far away. Although they could see the mechanism being triggered, they could not see the sagging. The location of Wang Fugui's station could touch the mechanism, so they could naturally see what the sagging would look like.

Chen Jian asked at this time: "What is below?"

"Uh, there are seventy or eighty centimeters long below, with a bronze pointed vertically. But many people died, just a nest, and many people were in their bones!" Wang Fugui said with a grin.

Hearing Wang Fugui's words, Chen Jian once again told him to be careful.

Generally speaking, this sinking trap mechanism will inevitably raise sharp objects in the pit, and the fallen people or animals will be directly penetrated and cause death.

The stone slabs are arranged in a rectangular shape in the passage, that is, the steps corresponding to the width. In this way, there are four rows of stone slabs. Wang Fugui is standing in the second row on the left at this time, and the first row on the left is tested!
