“The structure of this place doesn’t feel quite reasonable.”

Xu Wen stood in front of the first pavilion and looked up.

Yesterday, Wu Keming lived in a side room here.

To be precise, this structure that felt unreasonable was above the side of Wu Keming's residence, and was quite close to each other.

"What's wrong?" Qiao Ji followed Xu Wen and was the first to ask.

In the past, Qiao Ji didn't care about things other than making money, but now it seems that he has changed a little...

"Here." Xu Wen handed out the wooden board in his hand, and used charcoal to draw the figure he had just calculated.

Qiao Ji took it over, stared at it for a long time, and suddenly realized: "There is an extra space here!"

"Yes." Qiao Ji has always been very sensitive in numbers and space. Xu Wen's drawings are clear enough, and it is not surprising that he can quickly see them.

"Go up and take a look." Xu Wen took the lead and walked there. Qiao Ji was the first to follow behind. The others quickly followed, but they were blocked outside and could not get in after a while.

In the previous task arrangement, this building was temporarily named Shibiju Building No. 1. It has two floors, one floor is relatively large, with a total of five rooms on the front side. Wu Keming lives in a room near the west, which is considered a wing room.

Due to the terrain limitations on the second floor, it is relatively small, with only three rooms. Wu Keming took them up to visit before.

The three stone chambers on the second floor are as empty and have nothing.

They calculated through internal and external data that there should be a space on the far right side of the second floor, but when they came here, they only saw a small room, opposite the stone wall. The stone wall looked a little mottled due to weathering, but it looked complete and had no trace of a passage at all.

Xu Wen and Qiao Ji looked at each other, and Qiao Ji walked forward and began to fumble carefully on the stone wall.

"There is really no door." After a while, Qiao Ji took a step back and shook his head and said.

At this time, Xu Wen also walked over, one ear close to the stone wall, and the other hand tapped on the wall.

Stones are not wood, and they are not that easy to transmit sounds. He listens carefully and distinguishes them carefully.

"I'll try it." Sun Si also squeezed in and stuck it to the wall and knocked it on the wall and listened carefully.

His tapping gesture was different from Xu Wen. When he heard it, his ears moved a few times, which was very interesting.

"The wall is a bit thick, but the back is definitely empty!" After a moment, he looked up with great certainty.

There is indeed no door on the wall, but the back is empty, indicating that the space they calculated does exist.

What's going on? How can I get in without a door?

"Fourth Brother, come here to take a look!" After a while, Fang Jueming's voice sounded, a little dull, and it was coming from downstairs.

The crowd gave way, and everyone was curious, but still let Xu Wen be ahead.

The voice came from Wu Keming's study room, but when Xu Wen walked in, he did not see Fang Jueming's person.

Then, Fang Jueming and Xu Xihuai poked their heads from behind the opposite wall together and waved to him: "Fourth Brother, look, there is a road here!"

Hey, where did they come out from?

Xu Wen then realized that the right wing room where Wu Keming lived was not a single room, but two inside and outside. He just used people's visual blind spots to hide the inner room very cleverly. He could not find it without going to a specific location.

The inner room of this room is not a room to be precise, but a space, obliquely upward, forming a whole with the hidden space above, that is, a complete space, extending back into the mountain and leading directly downward.

It is obvious that this space is also naturally generated, and the builder then transforms and reinforces it on the original basis to make it take shape.

The most important thing is that it goes straight to the abdomen of the mountain, and it looks like the secret path they are looking for!

The secret path is located in the belly of the mountain. It looks flat at the feet, but it is very dark.

This darkness is extremely pure, secret and deep. With the faint light from outside, it looks like there are countless monsters hiding in the depths, which almost makes people feel a little dizzy.

Xu Wen looked in and was about to turn around and greet him when he saw Xu San walking in from the door, holding two torches in his hand, one in his hand, and the other hand was handed to Xu Wen.

"I'll go down." Fang Jueming was right next to him, wanting to take the torch, Xu Wen shook his head, took it first, and called out: "The fourth brother goes with me."

The secret passage is too dark, and Sun Si is particularly sensitive to his voice, which can make up for this flaw.

Sun Si hurried over and took the torch from Xu San's hand.

The others had no objection, and Xu Wen's judgment was their decision.

"Tell me if there is a strange voice." Xu Wen said to Sun Si, and Sun Si nodded immediately.

The light of the torch temporarily dispels the darkness in front of them and illuminates the road under their feet. The light continues to extend forward, and clusters of darkness escape one after another like panic.

This is a completely unfamiliar environment. Although Xu Wen was not nervous, he was still very alert. While walking, he observed the situation around him.

In such an environment, the torch is for lighting, and the other is to help confirm whether the space is completely closed and whether there is oxygen.

They kept walking forward and could feel the road under their feet slowly going down, but the torches kept burning with no signs of getting dark or extinguishing. It can be seen that the mountain road is very oxygen-enough and the ventilation is quite good.

Judging from the stone walls on both sides and the road at the foot, this mountain road is mainly generated naturally, and is a crack that naturally breaks out in the mountain, which happens to be connected to the crack where the stone wall lives.

So the builders of Shibiju used it and made a secret path to the foot of the mountain.

"Well, what's the sound?" Sun Si suddenly turned his head, then bent down, and picked up something from the ground.

His ears were indeed amazing, and Xu Wen didn't notice it until he bent down and realized that there seemed to be an extremely slight sound of gravel rolling just now.

"What is it?" Xu Wen put the torch over.

It was a piece of gravel, only the size of a finger, and it should have been kicked by Sun Si just now.

Xu Wen took it and touched it, then immediately said with a light "Huh" and said, "This is... bluestone!"

The stone walls are mainly granite, supplemented by bluestone and bricks.

Tianyun Mountain originally produces granite, and most of the stone walls are used on site, but Xu Wen has never figured out how bluestone and fired bricks are transported.

Now it seems that it was shipped here?

They walked down a while, and Sun Si discovered a piece of tiles left in the corner - very complete tiles.

After this, Xu Wen finally confirmed that this is the road, which was used to transport materials when Shibiju was built, and now it was used to transport supplies when Wu Keming stayed!

In the flash of lightning, he thought of another thing.
Chapter completed!
