Standing up again, the man in the dark stuffed all the fingers of both hands into the groove, and then pulled the surface wall hard towards the end of the secret passage, and after a few seconds, the wall actually moved slowly, covering the secret passage exit little by little.

This person expected that the people on the third floor would definitely come out of here, because he thought that the people above only knew about this gap, so Liu Hang not only helped Yun Yeyao crack the secret of the sand, but also helped him confirm the secret passage in and out of the third floor in the tower, which was very important.

From this, we can see that the person who is closing the secret passage is a person who has not heard and seen Liu Hang's previous actions.

As the surface of the wall is about to move to the bottom, the person pushing it can only stand diagonally on the pool countertop, and the movement looks like it could fall off the countertop at any moment.

With all the work done, he crouched there and gasped for a long time, the only faucet had begun to release water, and the pipe was stretched straight against the water pressure, because he turned the faucet to the maximum, and he knew that at this moment, the water was pouring into the sand below the floor on the second floor.

The sand would flow under the floor of the hexagonal walls, but it would never stay there, and the water would crash them onto the meeting room, the kitchen, and the dining room, where the walls would bang and fall down to the people sitting in the recreation room, and the sharp protrusions in the concrete walls, and the heavy, damp sand from the upstairs, would all be firmly pressed against those people, and they would die with a whimper.

And the third floor, part of the same area, will collapse with a bang because of the loss of the fulcrum, and the ruins on the third floor will fall down with people and be buried together.

Calculating the time, he fastened the lock on the wall panel, and waited to listen, the water would take some time to arrive, and he needed to confirm the location of the people upstairs. Fingers lightly pressed a small switch behind the wall, which was connected to the electric light in a certain area upstairs, and as long as the people upstairs screamed because the light went out inexplicably, he could be sure that they were not in the danger zone.

Mr. Actor continued, "The question we face now is, what exactly is hidden between the tank and the plank? According to Xiao Hang's description just now, the space there can completely allow a person to move around freely, Xiao Hang groped in it, and people must squat up and down, so from the analysis of width and height, that part of the space is still very large, I think the most likely thing hidden in it is sand, dry sand. ”

"As on the third floor, the sand is so fine and compact that it can be hidden a lot, and the water is not poured down from the top of the tank, but poured down from where the sand is hidden, which further shows that the sand on the third floor does not fill the inside of the walls, at least on the second floor the tank and the sand are above the pipes."

"So where does the water on the third floor come from? Most likely is the small bathroom under the stairwell, this small bathroom, the top of the shower head is a secret passage to the third floor, at first I thought the shower head there was an ornament, because I tried, the shower head could not put a drop of water out, however, now the answer has to be slightly changed. ”

"The shower head really can't release water, the water is directly from the pipe to the wall, according to the location, that place is close to the hexagonal room, and part of the water pipe of the shower head is connected to the wall and can't be removed, as long as Xiao Meng goes to check it carefully, you can know. If my reasoning is correct, the water pipe goes around the wall, and most of the hexagonal room leads to the water tank, just right down. ”

"The sand there was like sand bricks, so there was no floor, and they didn't spread out to other places. In addition, there is no air conditioning on the second floor, and all the heat is channeled up from the third and first floors, so the sand is more likely to be frozen by the cold air outside, but it is different when the water suddenly pours down, as long as it takes a short time, the sand that absorbs enough water will start to collapse and then flow into the floor mezzanine. Yun Yeyao finished speaking, and paused.

Liu Hang asked, "Then why don't you enter the wall?" If you want to crush the first floor, filling the walls with sand should be the fastest? "In fact, this question can be understood as long as you think carefully about Yun Yeyao's analysis of the first floor just now.

Liu Hang had memorized the location and route of the corridor on the third floor, and even if the light was low, he would not make a mistake.

In the afternoon of the same day, Liu Hang clearly saw Qin Sen pushing Xixi into the snow, and at that time he wanted to kill Qin Sen on the spot, but the task assigned by his grandfather was on him, and Liu Hang believed that Xie Yunmeng would definitely save Xixi in time, so he could only leave.

But in the end, Xixi still died, which was a huge blow to Liu Hang, and he would not forgive Qin Sen no matter what.

Slowing down, Liu Hang gradually approached the room where Yun Yeyao was, he didn't know if Grandpa was still there, if he wasn't, he would definitely be in the last room.

There is another thing, Liu Hang didn't dare to tell Liu Qiaopu, that is, the bright red in Qin Sen's hand was deliberately made by him, when Qin Sen was in the stairwell, he used his hand to reach the gap in the wall, Liu Hang happened to be next door, so he touched a little blood on the wall.

Now there are still blood stains on Liu Hang's fingers, he just wanted to scare Qin Sen at that time, but now it is different, he wants Qin Sen to pay the price.

Thinking in his heart, Liu Hang put his hand into his pocket, there was a small, sharp thing that he had just taken from the kitchen, holding the delicate handle tightly, cold sweat broke out in Liu Hang's palm, the muscles in his body were tensed, and the door he left just now was in front of him, Liu Hang couldn't help but take a step back.

If you really let grandpa know what he thinks now, without the law coming to him, grandpa will personally send him to the judge, Liu Hang's heart trembled, but the momentary hesitation did not stop him, he still reached out and pushed the door open.

But when Liu Hang entered the room, it was pitch black, and there was no one, so he immediately walked deeper into the corridor through the room, and when he passed by the large table, he didn't look down.
