Regarding the problem of sand, in addition to Liu Hang being cracked, there is another person who is also carefully studying, and that is Wen Manman.

The grocery store owner and her groped around the second floor of the restaurant, and although not every crack in the wall had sand leaking out, it was true that the damp sand could be felt from the walls, and the occasional sand fell from the ceiling.

After returning to the room, Vinmanman and the boss began to analyze the matter.

The grocery store owner said, "Little girl, what do you think the sand is for?" Wet sand like this will quickly freeze on the mountain, perhaps, Wen Yuya wants to make the wooden walls on the second floor stronger. ”

"Uncle, you can call me Manman, that's what the people in the house call me." "I don't think that's entirely the case, the reason why the sand is so wet is probably related to the water that was sprayed overnight last night, and I think the sand in the wall was just a little wet, or it kept a certain amount of humidity, but it was not enough to make it clump inside the wall, but not enough for it to flow out of the cracks in the wall," said Vanmanman. ”

"The reason for maintaining a certain humidity is that the snow on the roof melts and seeps into the sand. When winter comes, only the layer of sand close to the perimeter of the house will freeze, and the rest of the sand will remain in the same state as in spring and autumn due to the indoor air conditioning. You said to make the walls stronger, and there may be this reason in there, but I think the more important reason should be to increase the weight of the second floor. ”

"Why add weight? Maybe I am afraid that the wind and snow will blow down the wooden structure of the house, but I don't think it is appropriate to do this in the mountains, the wet sand will make the wooden walls decay faster, if you want to make the house stronger, the second floor is also built into a brick structure, and the snow melts every year It is easy to cause the house and the interior to get damp, why install a sprinkler device on the roof? ”

"It's all very strange questions, I can't figure it out at all. As a result of last night's large amount of water, the sand and wood absorbed too much water, and although the water froze instantly due to the cold outside, the air conditioner in the room melted it little by little, so that the mixture of water and sand flowed out of some of the wider gaps in the walls and stuck to the walls, while the ones on the roof fell off easily. ”

Hearing this, the grocery store owner said: "I remember one thing, Manman, after the side house of the strange house was burned down, we found that the remnants of the second floor of the side house are also wooden structure, but the first floor is made of cement bricks, which is very similar to the restaurant structure you just mentioned, but we have no way to determine whether there is sand hidden in the wall?" ”

"Off the walls? Unlikely! The partial house itself is built on top of the cliff, and the lighter the weight of the house, the better, if the cliff is crushed, the people in the partial house will not be able to escape at all. "So I don't think there's any sand on the wooden walls." ”

"This kind of thing can't be so arbitrarily concluded," the grocery store owner retorted: "An Ze, who built the treacherous house, was originally a crazy person, and I think his thoughts must be very different from those of us, An Ze was burned to death when he was taking a nap in the side house, and when the police found the body, the person had already become charcoal, because there was no suspicion of murder at all, so the police did not carefully examine the charred corpse, and soon let his daughter be buried." ”

"Now that I think about it, there was always a terrifying atmosphere in the events at that time, how did the fire burn? It came from the kitchen, but it didn't originate from the kitchen, and I still haven't figured out the reason for the investigation at that time. The police also didn't announce it in the newspapers, which is really weird. The grocery store owner said as he lamented that once a mystery is formed, it is like a memory that is difficult to erase from people's hearts.

Wen Manman thought, she looked at the walls around her, and always felt that something was wrong, what was wrong? She got up and paced back and forth in the room, and the grocery store owner and his wife were already very tired, so they sat together and quietly watched Wen Manman's movements, and after a while, the proprietress began to doze off with a little relaxation.

Of the people in the room who were still struggling to think about the sand, only Wen Manman was left.
