The kick kicked by the policewoman was heavy, but for a load-bearing wall, it was simply a mayfly shaking a tree, and it would not have any effect. But the strange thing is that when Xiao Xiao retracted his movements, the wall between the entertainment room and the living room actually shook violently, and there was something like wall ash spilling from above.

Everyone was attracted by the sound coming from this side, and for a moment only the sound of Yu Cha gasping was left in the space, and Mei Xiao was engrossed in watching the movement of the wall, after listening to Yu Cha's description just now, she had a bold idea, but she didn't know if it would work.

To explain the small idea, we have to go back to the structure of the card villa, in the previous narrative, in fact, there is a key point that has not been said, Yu Cha clarified the problem that Mei Xiaoxiao is not completely ignorant, she is not very good at playing cards, and she does not like this kind of noisy entertainment where four or two people get together, but in her spare time, she will play the cards that the children put on the table like arhats.

The small game is very simple, that is, find a central support point, and then slowly build carefully around the support point, as long as the center point does not collapse, other cards are fine.

Yu Qia said that the principle of the treacherous house comes from the load-bearing rules of solitaire, individual cards are very fragile, but put them on top of each other, and then stand up against each other, you can put other things on it, as long as the weight is less than the load-bearing capacity of a layer of cards.

For example, placing two cards in an upside-down V shape with the tips facing up is the first step and the most difficult step to stand on, and then, with a tray on each side of the V, the shape of the moment is like a spire tent closed around the perimeter, and after this basic frame is firmly established, the next step can be extended infinitely, expanding the scope of the first layer.

However, this solidity is built on the V at the neutral point, and once this V disintegrates, then everything on the side will collapse in an instant.

Now let's look at all the structures on the first floor, which are large enough to be divided into two fields (let's ignore the blue tower embedded in the walls of the recreation room, which is also seen as a square room).

In this way, the entertainment room, dining room, kitchen and the hidden space that enters the second-floor mechanism form the first Tian character, in which the four corners of the cross in the middle of the Tian character, and the lower left corner is where the speaker is located, that is, the secret door to enter the hidden space; The upper left corner is in the hidden space, and on the side is the vertical staircase into the second floor, and from here, it is the small room that Liu Qiaopu once took everyone to stay for a long time in order to wait for Shan Mingze played by Liu Hang to return to the team.

The location of the bar counter of the restaurant in the lower right corner was completely blocked by the bar, before, Wen Manman was kidnapped inexplicably and thrown in the bar, if it wasn't for the sound of Xiaoxiao, it is estimated that she would not have escaped at all (provided that Wen Manman was really kidnapped by the murderer, not a scene directed and acted by herself), so this corner is very hidden.

The corner in the upper right corner is very crucial, the two walls it is connected to, one is not a complete wall at all, because a large part of the middle is a glass sliding door and a heavy curtain, and the other wall can be opened above, just below the movable wall upstairs, which supports the entire movable wall and also serves as a stepping point for the parties entering the mechanism.

On this wall, next to the glazed table in the kitchen, people who come down from it can use the glazed table as a second stepping point and will not get hurt because of the height of the wall. Terror, Qiao Keli, Liu Hang, and Yan Muheng have all been in and out of this place before, and now it is no longer a secret as an entrance.

Please be patient, let's continue to look at the two Tianzi on the first floor, and it can be seen that the four corners in the middle of the first Tianzi completely bear all the weight of the passage and movable walls of the hexagonal hall on the second floor, that is, if the four walls in the center of Tianzi collapse on one side, at least the general building above will collapse.

Let's take a look at the second Tianzi, which is composed of four parts: the dining room, the kitchen, the hostess's room and the living room, where the four corners of the cross-shaped wall in the middle should be empty and do not bear the weight of the wall on the second floor. Because above this part is the area of the hexagonal hall, in the center of which there is no furniture and no horizontal walls.

Therefore, the four corners of this part ignore the past first, let's look at the four walls around Tianzi, they form 12 corners with the cross-shaped wall in the middle, which acts like the 12 V-shaped fulcrums of the card villa, and every two fulcrums bear the weight of a wall.

It may be a bit vague to say this, but if we look from left to right, we start with the middle two corners of the wall represented by the leftmost vertical side of the Tianzigzag, which are next to each other.

First, a line extends from the center of the corner on the upper left to the middle point of the left half of the horizontal left side of the field, forming the first wall of the hexagonal hall. Then continue to draw a line along the wall represented by the upper horizontal wall, through the middle two corners of the wall, extending to the middle point of the right half of the horizontal horizontal to form a second hexagonal wall.

Next, continue to draw a line to the lower right, extend to the middle two corners of the vertical wall on the far right of the 'field', and form a third wall at the center point of the corner facing up, and so on on the lower part of the 'field', a complete hexagon is formed.

Therefore, to collapse the hexagonal hall on the second floor, it was necessary to destroy almost all the perimeter walls in the left half of the first floor, because it had so many load-bearing fulcrums that one wall could not be overhung to make much difference. It is not possible to destroy the fulcrum in the middle, and the floor will not collapse immediately.

In this way, there is an error in Liu Hang's analysis upstairs, even if the sand fills the walls around the hexagonal room, it may not be able to crush the supporting walls downstairs, because the weight of the six walls is dispersed, so what is the real role of the water tank and sand on the second floor? In the end, this matter will have to be solved by Yun Yeyao, of course, Liu Hang's reminder and the fact that Wen Manman found it in the periphery are indispensable.

The reason why Mei Xiaoxiao had to kick the wall between the entertainment room and the dining room violently was because she thought of the location of the passage on the second floor and the way a few people went up and down the stairs before, and found that all the mechanisms in this part were concentrated on the load-bearing wall in the middle, if the load-bearing wall in the middle was not firm, then the people walking upstairs would be in danger, so she wanted to give it a try.

I thought that the wall would not move at all, and she was also taken aback, and immediately, she became nervous, the teacher, Xiao Meng and Xiao Yao Ke were all on it, it was so fragile here, it would affect the third floor, and there were powdery things falling down on it, indicating that the inside of the cement wall was very loose.

"Yan Muheng, is the wall above also a cement brick structure?" Mei Xiaoxiao asked.

Yan Muheng immediately replied: "No, there is a wooden structure wall on it." ”

"Then why does the powdery stuff keep falling, is it sawdust?" She squatted down and wiped the floor with her hands, and then she realized that it was actually sand that had fallen, and it was very damp sand.

"Where did all this stuff come from?" Mei Xiaoxiao asked casually.

Everyone leaned over to look at it, their attention was focused on the sand, no one knew what it was for, and the walls felt very fragile after a small kick, and there seemed to be a slight cracking sound coming from inside. Spread your hands a little and ask everyone to step back a little to avoid accidents.

She glanced back, and suddenly found that there was one less person on the first floor as far as her eyes could see, and she was stunned for a moment, and then shouted:

"Grandma Tang......"

——

The emaciated shadow sensed that something was starting to be wrong, and it was not something he could explain, so the shadow chose to retreat, and while everyone was studying the walls and sand, he secretly moved towards the bathroom door.

He is more familiar with every part of the treacherous house than anyone else, as long as he passes through the double doors there, he can directly enter the secret passage, and the black shadow has to be hidden again unconsciously, those criminal policemen are too powerful to investigate to such an extent, the development of events in the treacherous house is no longer beyond the control of the black shadow.

Just as he was making his way into the bathroom, a hand suddenly came from behind his back, and something like a blade hit his neck.

The voice that changed its tone approached his ears, and the threat of death kept the black shadow from moving.

"Listen, from now on, if you don't want to be discovered by the criminal police all the secrets, then you can find a way to restore that sand for me, the treacherous house must not have an accident, I will keep an eye on you all the time, if you find that the treacherous house has fallen a wall, you will have an extra knife on your neck, until you cut the trachea, understand?"

"You, who the hell are you?"

“Eternal”

Hearing the code name of Eternity, the dark shadow trembled violently, fear spread in his heart, almost stopping him from breathing, Eternal should have died a long time ago, fifteen years ago, when this treacherous house was still a mirror house, the eternal heart was eliminated by him by all means, why did it still appear?

"You ......"

The black shadow wanted to say something, but was interrupted by the person behind him, he said: "I don't have time to talk nonsense with you, hurry up, go up to the third floor, if he can't come down safely, do you know what will happen?" ”

He ...... Who is it? ”

"You know."

As the conversation ended, the shadow felt his neck loosen and the person behind him was gone, and he looked back to see that there was nothing behind him except the bathroom door.

Touching the cold sweat on his forehead, the black shadow flashed into the inside of the secret passage of the tower, and began his actions, at this moment, whether to save the people upstairs or destroy the treacherous house owner's house, all in his thoughts.
