As soon as Wang Fugui said this, everyone's eyes looked at Wang Fugui's lighting, where it was shining.

Chen Jian also took a few steps back at this time and saw clearly where Wang Fugui's lighting lamp was illuminated.

At this time, the lights gather on the last step, that is, the step that has been shortened by half the width. The height of this step and the ground is the same as the height between the steps and the steps above.

However, the height of the last step has some wear marks in the place connected to the ground. This mark is horizontal and horizontal, covering the entire step from left to right. The height of the wear marks is about a few centimeters, and it will definitely not exceed three centimeters.

This position was originally extremely hidden, and with this wear height, it would be even more hidden. If Chen Jian had not stated the key point of gravity triggering, Wang Fugui would not have found the place where the mechanism was so quickly.

There is no doubt that the wear of the last step fully shows that this step can be moved and move downward. This is the wear caused by gravity downward pressure, which can be 100% certain. The last step is the opening mechanism of the stone door. The way to open is gravity contact, or gravity downward pressure.

Wang Fugui walked to the steps first and stood still, without any reaction.

This was not unexpected, because before that, only Wang Fugui went down the stairs. When exploring the space in this space, Chen Jian stood on the last stairs and the stone gate did not start.

Chen Jian was the second step to stand firm, but the stone gate was still not opened. Chen Jian waved and said, "Let's come back first, stand on the steps above, and stand one by one to the last step!"

Hearing Chen Jian's words, everyone returned to the stairs, and Yang Wanming stood directly on the last stairs without moving upwards.

At this time, there were already three people standing on the last step, but the mechanism was still not triggered, so the stone gate naturally did not open.

Chen Jian and the other three stood in the middle of the steps, on the left and right sides, or in other words, one person could stand on the left and right sides, that is to say, two more people stood on the left and right sides, and the steps were basically full of people.

The reason why people are basically full of people is because they can still stand a few more people.

However, Chen Jian said at this time: "Stand two more on the left and right sides!"

Hearing Chen Jian's words, Xuan Mingzi and Gao Bing stood on the edges of the left and right sides of the steps.

At this time, Chen Jian and the other five stood there, and they were basically full of people. After Xuan Mingzi and Gao Bing stood up, Chen Jian and the other five clearly felt that the steps began to slowly sink. After sinking about a few centimeters, the steps stopped sinking.

At the same time, the third stone door, which is the right-most stone door facing Chen Jian and others, opened.

This stone door is opened rotatingly, with the pivot point on the left side of the stone door, which is the same way to open it like a modern swing door.

However, modern doors use folding pages to connect the door to the door frame. This stone door is definitely not like this. As for what is going on, you have to check it before you know it.

"Will the stone gate be closed after we leave the steps?" Chen Jian looked at Wang Fugui and asked.

Wang Fugui spread his hands and said, "I don't know, I'll just try it."

Wang Fugui spoke, walked down the steps and towards the third stone door that was opened.

Chen Jian said at this time: "You stand on the back steps and I'll accompany him to take a look!"

After saying this, Chen Jian quickly stepped down the stairs and followed Wang Fugui towards the third stone door that was opened. Xuan Mingzi and the others left the last step and retreated to the penultimate step.

As Chen Jian and the others left, the gravity naturally disappeared, and the originally sinking steps slowly rose and returned to their original position.

However, the third stone door that was opened was not closed.

Wang Fugui was standing outside the stone gate at this time, carefully observing the pivot point where the stone gate opened, that is, to the left side of the stone gate, and said: "The axis is above and below, I don't know if it is the entire pivot through the stone gate!"

Chen Jian patted Wang Fugui on the shoulder, and then pointed to the last step to restore it to its original state.

As for whether the axis runs through the entire stone gate, it is not important in Chen Jian's opinion. It does not require careful study. It is better to restore the steps to the original state. The stone gate is not closed.

"You guys are standing up and trying five people!" Wang Fugui understood what Chen Jian meant and shouted at Xiao Yurou and the others.

Soon, Xiao Yurou and the others stood up again and the steps slowly sank.

This time, the stone gate was closed.

"Same!" Wang Fugui said at this time: "The sound is like the two stone doors we came in. Pull the right side and the left side. Here we just step on it once, step on it again, and wait until the steps are restored to their original state, and then the five people will open again!"

Without Chen Jian and Wang Fugui's reminder, after the stone gate was closed, Xiao Yurou and the other five retreated to the penultimate step.

When the last step returned to its original state, Xiao Yurou shouted, "Do you want to open the stone door again?"

There is no doubt that once the mechanism is found and knows how to turn it on, it becomes a effortless task to turn it on.

"Open it!" Chen Jian replied.

Xiao Yurou and the others stood on the last step again, and the third stone door opened again.

"There are two stone doors that have not been opened!" Chen Jian said to Wang Fugui.

Wang Fugui nodded and asked Chen Jian to walk back. While walking, he said, "There must be still steps that can be stepped on, and the mechanism is on the steps!"

Facts have proved that Wang Fugui was right. This is the mechanism. It was extremely mysterious before it was cracked. Once it was cracked, there was no magic at all.

The remaining two stone doors also have corresponding steps. Wang Fugui illuminated them with lights and quickly found them.

Walking from top to bottom, there are traces on the tenth step. This step corresponds to the first stone door, the twentyth step, the middle stone door, the last step, the third stone door, and there are traces to follow, because the last step is the thirtyth step.

Ten, twenty, and thirty, these three numbers are where the mechanism that opens the first, second, and third doors are located.

The opening mechanism was found, and at this point, all three stone doors were opened.
