The door on the wall is open inward, so as long as it is blocked from the inside, people outside will definitely be discovered if they want to push it open. After making these preparations, Liu Hang groped along the wall, hoping to find a light switch, or something else that could be used for lighting, and he didn't always have a small flashlight on his key ring.

But after groping around, Liu Hang was very disappointed, there were no lighting tools in it, and the places that could be touched on the wall were smooth, and there was not even a switch. Liu Hang was also very helpless, he lowered his arm, looked around, and tried to adapt to the darkness in the room.

Fortunately, the room was not so dark that he couldn't see his fingers, after getting used to it for a while, Liu Hang began to observe the surrounding furniture, and the first thing that caught his eye was a bunch of things like boxes, neatly stacked one by one, in front of the box, there seemed to be something slender leaning there, not like an adult, small, slender, but like a child's body.

Liu Hang put the knife in his hand back in his pocket, his heart was pounding, and he slowly approached the long thing, his footsteps dragged on the ground, showing his willingness to retreat, but Liu Hang persevered, he did not retreat, but walked all the way to the front of the box.

When there were still two or three steps away, Liu Hang suddenly stopped like a sudden brake, and the whole person shook slightly. He felt dizzy, and the things on the ground were wrapped in strips of cloth, and between the strips of cloth, he saw black, hollow, open lips with a few teeth still remaining in them.

Liu Hang gasped, it was a white bone wrapped in a mummy, and the white bone was already covered with dust, large and small spider webs were connected between it and the cabinet, and huge spiders could be vaguely seen crawling on it.

Liu Hang didn't squat down, not because he was afraid that his legs were already weak, but because he found some very strange problems: first, the problem of temperature, after entering the room for a few minutes, Liu Hang felt that it was colder here than in the corridor, indicating that the room was definitely not closed, and there must be some gap that could lead to the outdoors.

Second, there is the problem of taste, although there are mummified bones here, there is no rancid smell at all, and there is only a smell of dust everywhere. It's the same in the hallway outside, otherwise this room would have been discovered a long time ago. Thirdly, the problem of light, it's good that it's very dark here, but it's not completely dark.

After the eyes get used to it, I always feel that there is a faint light penetrating in, but I can't find where the source is? There are also no notches and windows in sight. And the light in the room, as if it was all hoarded in the void, made people feel depressed and depressed.

Liu Hang's footsteps slowly retreated, this room was too weird, he couldn't touch anything, everything had to be left untouched, and he would investigate after his grandfather came, at this point, Liu Hang's mind was still clear.

Mei Xiaoxiao asked: "Old Yu, how much do you know about this house?" ”

"I know it because I used to be involved in the construction of this house." Yu Cha's answer was shocking, and Tang Meiya asked him: "Xiao Cha, how did you get involved in the construction of this house?" ”

Hearing Tang Meiya's question, Yu Cha didn't open his mouth, but lowered his head first, and explained: "Xiaoya, you also know that when my brother was involved in the crime of child trafficking, I was also involved in it, although I didn't really act with them, but my brother asked me to pretend to be a renovation worker and sneak into various houses to find out the news, if there are children's homes, that's the best." ”

"At that time, I had my own engineering team, and I took on all kinds of work, half of which was to deal with my brother, but in fact, I didn't tell my brother the real information about others. The other half is to earn money as soon as possible, so that he can get away from his brother and live an independent life. ”

"For me, I can't bear to report my brother, and I can't agree with his brother's criminal practices. About 20 years ago, before I entrust Yaya to you, I received a job to build the Treacherous House, and the person who came to me was none other than Anze, the first owner of the Treacherous House. ”

"Do you remember what he looked like?" Mei Xiaoxiao asked.

"I don't remember exactly, my memory has deteriorated very much over the years, and I only vaguely remember him looking like Sven, wearing round-rimmed glasses, a wide chin, messy hair, and unshaven stubble on the sides of his cheeks and chin."

"Anze's request to me is to build a house that satisfies him, as for what kind of satisfaction, as long as we build it according to his requirements, except for giving advice, don't ask what the reason is? At the time, I was very confused, but because he was paid well, I didn't say much. ”

Chokley asked, "Is there a little apprentice in your 20s who stayed in the treacherous house later?" He had heard Horror talk about the past, and he had a certain understanding.

Yu Cha said: "At that time, because the treacherous house was not contracted by one of my engineering teams, I don't know if the person I am talking about is the person you asked, after we finished, there were no small workers left, but later, An Ze asked us to go over to repair the house, about once every six months, went to about two or three times, the last time I left, there was a worker in his early 20s who resigned, I don't know where he went after resigning? Did you stay in the Treacherous House? ”

"He was a very honest little worker, and he worked very hard, because he had a good temper and good looks, and I wanted to introduce my distant niece to him, but after I resigned, it was gone."

"Yes, Officer Mei, that's him. He found that there was a basement in the study room, and the space under the entrance of the basement was also separated by wood, between the wood and the rock, a large amount of sand was buried, which would absorb water and help keep the wood dry, but if it was not changed for a long time, when the sand was full of water, the excess would still seep into the wood, which would cause greater damage. ”

"Further down in the basement was the rock hole where I was locked, and the little workers had to turn back to me to report that the sand was filling in the sand to increase the weight of the foundation. But on this mountain, it will be completely counterproductive, and increasing the weight of the foundation is not equivalent to increasing the gravity of the cliff? I couldn't figure it out, so I wanted to sneak up to the second and third floors to check if there was any sand in there. ”

"But I and the small worker looked for a long time, and did not find a way to go upstairs, so I had to give up, a maintenance period is about a week, plus the round-trip journey, about ten days, we have no reason to stay longer, in order to further explore the treacherous house, I signed a long-term maintenance contract with Anze before leaving, and promised to come once every six months."

"Did you find anything out of the ordinary? Also, you haven't explained the specific reason why you call the house a card villa. Mei Xiaoxiao asked, and Yu Cha's words made her want to explore this house even more.

——

Liu Hang was attacked inexplicably, lying alone in an unknown room, and Liu Qiaopu wanted to go to the last room on the third floor to find him, in this case, unless Liu Hang woke up in time and took the initiative to reconcile with them, otherwise, the old man would never see his grandson.

There was a slight rustling sound in the room, as if something was constantly flowing around Liu Hang, and the same sound was being made in the inquiry room where Liu Qiaopu and they left, which was much brighter than the room Liu Hang was.

As we look closer, we see that every crevice in the wall of the wooden plaque is spilling out sand, which is small and densely flowing outward, gradually converging on the floor.

The walls and floors are not visible at the moment, maybe just the sand hidden in the walls has flowed out, but these sounds have sighed a horror to the already strange space, ancient Egyptian legends, mummies will turn into sand and burrow into any place, maybe the white sand grains we have here will also turn into evil spirits and burrow into the hearts of the survivors.

After the blood stains in the room were almost cleaned up, Wen Manman and the boss threw the blood-stained bedding on the bed downstairs, so that they could finally rest for a while, Wen Manman stood in the center of the room and observed, the proprietress was lying on the bed, and the boss was taking out the sheets, blankets and other things that could be used from the package to cover his wife.

"The floor here is also painted with cement, is it trying to disguise itself as a brick structure?" ”

"It's impossible, what's the need to camouflage the floor, and we don't feel like a wooden board at all when we step on it, could it be that the walls on the second floor are made of wood, and the floor is made of cement bricks? Isn't the floor here the ceiling downstairs? The grocery store lady responded.

Wen Manman stepped on the floor a few times, the expression on her face was still confused, she was thinking, this little girl had the same keen intuition as Yun Yeyao, at the beginning, it was the first time she discovered the fact that Yun Yeyao liked Xie Yunmeng.

After thinking for a while, Wen Manman sat down on the edge of the bed and said, "I don't think it's that simple, Officer Xie said that there is a sprinkler device on the roof here, and it was because of it that it was activated last night that the house was frozen, but the frozen house is just to freeze a corpse, let you be witnesses?" It's also too much work. ”

"Or rather, I want to trap you, but in reality, it's useless to trap you, is it? Moreover, the heavy snow on this mountain and the blocked mountain road are already difficult to break through, and no one can walk, and the murderer's frozen house is simply redundant. So what exactly does he want to do? ”

The grocery store owner and his wife were speechless by his question, and they could only listen to the little girl continue, "Although I can't say why, one thing is certain, the murderer definitely didn't freeze the house for the people who stayed in the house, he must have another purpose." ”

"Then guess what, little girl, what is the murderer for?" The grocery store owner couldn't help but ask.

Wen Manman just shook his head and said, "I'm not a detective, if only that Mr. actor was here, he must have thought of something more concrete, you know?" He and the criminal police have now found out the secrets hidden by many people in the house, and the case is becoming clear step by step, he is really a very smart person. ”

"Alas! It's a pity that we can only wait here for the results. The proprietress sighed and lay down on the bed, she was also really tired.

Xie Yunmeng was seriously watching Liu Qiaopu's actions, suddenly felt the movement in his arms, and looked down at Yun Yeyao.

Yun Yeyao said: "Xiao Meng, check the walls, all the walls, including the ceiling, be quick!" I heard the sound of something flowing, very soft. ”

"Walls? The walls are normal! Did you find anything? ”

Xie Yunmeng's voice attracted Liu Qiaopu's attention, and he also leaned closer to Yun Yeyao and asked, "Xiao Yao, what did you find?" ”

"Teacher, I told you, Xiao Hang is not here for revenge, there must be some reason, he is not in this room, it proves that he must be trapped somewhere, I heard a similar sound here as the corridor just now, it should be from the wall, you let me down, quickly check the wall, there will be flaws."

It was only at this time that Liu Qiaopu began to believe Yun Yeyao's words, his heart beat sharply, and he and Xie Yunmeng hurriedly placed Yun Yeyao on the bed, but in the next second, Yun Yeyao propped himself up from the bed despite his injuries.

He said with all his strength, "It's sand, there's fine sand on the bed, teacher, do you remember what you found in the basement?" ”

"The sand, the sand hidden in the mezzanine of the wall, the air in the basement was humid at the time, and I found that the sand in the wall absorbed the moisture and then re-damp, what does that have to do with this?" Yanagihashi asked rhetorically.

"Wait, I can't figure out an answer yet, you check the walls to see if the sand is spilling out of the walls, and if the sand is damp."

"Okay, Xiao Yao, don't worry, we'll check it now."

Everyone was mobilized to inspect the wall with the criminal police, but only Yun Yeyao knew that such an action was not enough, he had to figure out the real reason why the sand was here, and at this moment, there was one person who thought of Yun Yeyao's front, that is, the trapped Liu Hang.

Liu Hang was exhausted, the lacerations on his face and the knife wounds on his chest were deep in blood because of the exertion, the sweat had soaked his clothes and hair, and his eyes had become blurred, the furniture that the person was holding against the door was very heavy, Liu Hang couldn't move at all now, his hands were sore, and he wanted to regain a little strength by the wall again, but this was a drop in the bucket, if no one came to save him, Liu Hang might have to wait here to die.

"You're a criminal policeman, you can't say anything like this, remember, no matter what, you can't mess around here!" After speaking, Liu Qiaopu poked Xie Yunmeng's head with his finger and stood up.

He didn't immediately ask the other people who were scared stupid, but picked up Lian Fan, who had become Yun Yeyao's meat pad, until he came into contact with Lian Fan, the old criminal policeman was really stunned, his fingers touched Lian Fan's back, there was a bulge there, and the surroundings of this thing were full of blood!

A few minutes later, the old criminal policeman said a sentence in a low voice, this sentence was not for Xie Yunmeng alone, but to someone in the venue: "Everyone, Lian Fan is dead......

"What ?!!" The first person to exclaim was Xia Hongyu, who threw herself on the collapsed bed board and was stopped by the old detective, but it was clear in front of her that Lian Fan was lying there motionless, her back was already stained with blood, and under the clothes lifted by the old detective, a sharp stake was nailed through his body.

Xia Hongqi immediately collapsed on the ground and cried loudly, Tao Muqing was no better, leaning against the wall Tears kept falling, so far, the six college students who went up the mountain together, only three remained, Tao Muqing couldn't understand why things had developed to this point.

"Teacher, Xiao Yao's back is also bleeding!!" At this time, Xie Yunmeng's voice sounded again.

"What do you say?!!"

Liu Qiaopu immediately turned around, he helped Xie Yunmeng carefully turn Yun Yeyao's whole person over, tearing the clothes on his back, sure enough, the tip of the stake also hurt Yun Yeyao, on the edge of the spine, there was a blood hole, and there were traces of scratches on both sides of the blood hole, and blood kept gushing out of it, I am afraid it would be difficult to stop it for a while.

"Bastard!!" Xie Yunmeng covered the wound with a clean cloth and cursed.

Liu Qiaopu said: "It seems that Lian Fan died to save Xiao Yao, he must have seen the murderer's actions, and he didn't have time to remind us." ”

"Teacher, Xiaohang!! And Xiaohang!! Xie Yunmeng exclaimed: "It seems that Xiao Yao is right!" Xiaohang is also unlucky now! We're going to find him! ”

"No hurry!" Yanagihashi Puqiang held back the worry in his heart and said: "The murderer is among these people, and the most important thing is not to let him act again." I don't know what else there is in this room, there is no way, I can only take Xiao Yao to evacuate first, go downstairs and meet Xiao Xiao, so that you at least have one helper! ”

"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 wall crevices and stuck to the walls, while those on the roof easily fell off. ”

Hearing the reason, the grocery store owner said: "I remembered one thing, Manman, after the side house of the treacherous house was burned down, we found that the remnants of the second floor of the side house were also made of wood, but the first floor was 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 get out 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 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. It's really strange that the police haven't published it in the newspapers either. 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.

"When I uncovered the second layer of wooden planks with sand, I understood a little, behind the wooden planks, the whole large space was a huge water tank, looking at the extension, the water tank should have been stolen all the way to the locked door in the middle of the hexagonal room, that door I also entered, inside was a narrow passage."

"At that time, I hung the chain from the inside, because that passage led directly to the room at the bottom of the third floor, as for why I didn't want everyone to enter there too early, let Mr. Yun and Officer Xie explain it later, I will continue to talk about the sand issue now."

"If my judgment is correct, all the places between the middle of the hexagonal hall and the wall of the room on the left hand side occupy a huge water tank, which means that the water in the tank must have a very large storage capacity, but after knocking on the periphery, I found that the water inside has all been drained, and the damp sand should have overflowed the gap in the wall with the flow of water, because there is also damp sand on the wall of the water tank."

"The time when the water was released was probably when the mysterious man entered there, but at that time I had no way of knowing what the water and sand were for?"

"At that time, I had no way of knowing what the water and sand did. Liu Hang's tone was full of self-blame, and Liu Qiaopu said: "You have worked very hard, don't take this kind of thing to heart, let us solve it!"

Liu Hang shook his head and said: "But now I know, grandpa, although there are many things that I haven't sorted out yet, there is one thing that I know very well, that is, the crisis, the sense of crisis brought by these sands, grandpa, I think the only role of sand is to destroy the walls, but not the walls of the second and third floors, but the first floor." The sand on the second floor absorbs enough water, and the weight of the walls on the third floor must crush the first floor. ”

"Anyway, we have to go back to the first floor now, get those people out of the treacherous house, or hide in a hole in the rock, and then find a way to solve the case." Liu Hang gave what he thought was the most appropriate plan, what he said before, although it was a little chaotic, but Liu Qiaopu and Xie Yunmeng could roughly understand what he meant, the sand must be spread all over the wall, and the water in the water tank would probably have pipes to guide all over the wall.
