As soon as Sister Wang's words fell, Liu Hang couldn't wait to ask again: "But I just saw that it was indeed a human figure under the black cloak?" How could a little black cat wear a cloak like that? ”

"No, I don't know!" This time, Sister Wang didn't have anything to answer, she thought for a while and said, "Maybe it's air, right?" The black cat came out very fast, or the black cloak was too heavy, and it was propped up there all at once, anyway, I can't tell what the reason is. ”

Liu Hang was obviously not satisfied with this answer, he took a step back, stepped on his heels and stepped up a staircase, and suddenly bent down and picked up the black cloak, under which there was nothing but steps. Liu Hang stepped on the ground there with his foot, but he didn't move, and there was no sign of an underground entrance.

Only then did he throw the cloak back to the ground, crossed his hands on his waist, and looked around at the people around him, Lu Haoyu, Tao Muqing, Xia Tomato, Sister Wang, and the cook were not missing, Liu Hang shook his head, in this case, it was impossible for him to come up with a reasonable explanation, so he could only carefully remember the situation at the scene, and wait for the incident to report to the criminal police afterwards.

"You haven't answered my question yet, where are your grandfather and the others?" Sister Wang urged him.

"My grandfather and they can't come out for the time being, they have encountered some special situations, but with Officer Xie here, there will be no danger for the time being, I came out to confirm whether you are safe, because Xiao Yao's judgment has some deviations, and now it seems that there is no big problem, just find a way to get out."

After reconfirming everyone, Liu Hang continued: "There is another way not to go out from the movable wall on the second floor, you come with me, I hope the second entrance and exit will not be blocked." With that, he quickly walked down the stairs, and several others followed him without hesitation.

While walking, Xia Tomato was still complaining in a low voice: "It's really a crow's mouth, I didn't go out, so I just said that this kind of thing is not blocked!" ”

"You just don't say a few words, it's good that he was so seriously injured, and he didn't forget to come out to save us, how can you say such a thing!" Tao Muqing also reprimanded him in a very low voice, this girl made people feel very decent from the beginning, and she did everything she did and talked like this.

What they have to pass through now is the passage that Xie Yunmeng used when he went upstairs, and he can go directly to the secret passage of the tower, but it is still unknown whether he can get through, and Liu Hang is also worried in his heart, so he will speak more bluntly.

Whether these people can make peace with the small round will have to wait for a while for the time being, but in the stairwell they just left, some subtle changes have gradually taken place.

——

A pair of hands slowly stretched out from under the bed where Liu Hang was lying, these hands were wearing translucent plastic gloves, and then a bloodstained arm, and then half a shoulder.

When the whole person crawled out of it, except for his face, almost all other parts of his body were stained with Lianfan's blood, as well as the dirt under the bed, this person removed a layer of transparent things from his face and threw it aside, and we saw clearly that he was Eternal who was performing an autopsy upstairs, and I don't know where this guy came in, and no one found him.

When he came out, Lian Fan's body was flipped aside, and a large hole appeared under the bed, where the wooden stake had fallen horizontally to the ground, as if it had been pulled out from under the floor.

Eternal took off his coat in disgust, not forgetting to look out of the wall, but there was no one.

"Whew... It seems that my solution is quite good, and those people actually believe it. ”

After saying this, he returned to Lian Fan's corpse and continued to fiddle with it, hoping that Lian Fan's corpse could bring him more clues.

While Eternal was concentrating on the autopsy, two people walking around in another place were whispering.

"You say, why did Mr. Yun get healed all of a sudden?"

"Maybe Mr. Detective bandaged him and hid it, didn't you notice that he had changed his coat?"

"But the coat fits perfectly, and there is no bulging part on his arm, it doesn't look like it's wrapped in gauze!"

"I'm also weird, but his face is really exactly the same as Mr. Yun, there can't be anything wrong."

"yes, but I'm always a little worried."

"What are you worried about, Mr. Yun is a criminal policeman, not a murderer, and he told us not to tell anyone, he must have found that the murderer was among us, so he said that."

"Don't scare me, don't we be killed anytime and anywhere?"

"Hey! Who do you think is the most likely murderer? ”

"It's ...... me"

A third voice was suddenly inserted in the conversation between the two people, startling the person in front of them, and when they looked back, they realized that it was someone they knew.

"Are you crazy? Talking suddenly will scare people to death. ”

"Mr. Yun, please ask you something, can you tell me?"

"No, don't you admit that you're the murderer? We didn't yell at you to get you, and that's good. ”

"I'm just playing a prank, you know I'm under a lot of pressure, I always want to do something, I'm sorry, can I apologize? Tell me! ”

"It's not that we don't say it, it's Mr. Yun who took care of it, so you'd better not ask."

"Humph! I can guess if you don't say it," the third person was a little unrelenting, he actually didn't guess anything, and deliberately said the words of the two people in front of him: "I saw the body of that person just now, is there someone hiding underneath?" ”

"You...... Don't talk nonsense! Someone quickly covered his mouth, and the other was also frightened by him.

The third man immediately put on a treacherous appearance and said, "It seems that I guessed correctly. After saying that, he bypassed the two people in front of him and walked by himself.

The two men in a panic began to speak again.

"Oops! I'm scared to death, do you think he's going to sue that guy, if he suspects us of doing something, he'll be in trouble. ”

"Probably not, he said it, that guy doesn't necessarily believe it, besides, it's not certain whether he himself is a murderer, why doubt us?"

"That's right, but in case of suspicion, it's hard to say clearly, not to mention that now everyone is in a sensitive mood, we can't be wronged."

"Don't worry, I believe that Mr. Yun will not harm us."

This was the end of the conversation, and although the last person to speak spoke in a positive tone, the expression on his face was as uneasy as the other's.

——

Liu Hang took a few people back to the middle of the hexagonal hall, at this time, Sister Wang and the cook followed closely behind him, behind them was Lu Haoyu, while Tao Muqing and Xia Tomato fell at the back of the line, and the two little girls snuggled together, looking uneasy.

Let's wait a minute, Liu Hang walked alone towards the entrance and exit, he wanted to check first, why couldn't the movable wall there move, if it was sand, why didn't the sand fall downstairs?

And he also wanted to figure out a question, not far away, why did the people upstairs find that this road is impassable, and didn't immediately call the downstairs to ask for help?

Liu Hang didn't ask this question, but wanted to confirm it himself, and walked to the seam between the floors, he touched the ground with his hand, it was very wet, and he could feel the sand rolling in the palm of his hand.

It seems that Yan Muheng is right, the sand has indeed flowed here. Liu Hang withdrew his hand and pushed the part of the wall that could be moved, the mechanism here was all controlled by the movement of the wall, and the floor was also moved with the wall.

After pushing hard a few times, the wall did not move at all, and this time, Liu Hang no longer wasted time, and shouted loudly downstairs: "Officer Zhang, can you hear me?" ”

"Officer Mei! Answer me when you hear it. ”

"It's useless, we all shouted just now, and there was no response." Tao Muqing, who was at the end, said, she and Xia Tomato moved a little to the side, looking at Liu Hang, Lu Haoyu should have covered their sight just now.

Tao Muqing continued: "The voices of several of us are always louder than yours, maybe the sand and water are mixed together, blocking the gaps, so that the sound cannot be transmitted downstairs. ”

"Is there really such a thing? Sounds are not objects, they can be heard through the walls, okay! Lu Haoyu retorted to her, Tao Muqing closed her mouth, and moved a little more to the side, with a hint of uneasiness in her eyes, as if she was guarding against someone.

Xia Tomatoes moved next to her, and Lu Haoyu didn't care, and didn't pay attention to the two little girls at all.

Liu Hang asked the cook: "Did you use a soundproof board here?" ”

"I don't know, although I was here when the house was built, but what materials were used, Anze never told me, and I don't know anything about it." The cook replied honestly.

Lu Haoyu said: "I don't think it's possible to use soundproof panels, the walls and floors can be opened, so what's the use of using soundproof panels?" ”

However, his point of view was not agreed with by Liu Hang, "Although the walls and floors are useless when they are opened, when they are closed like now, the soundproof panels are useful, and from this exit to the bottom, it is not directly to the entertainment room, and there is a secret room, so it is completely possible that the sound cannot be transmitted." ”

Liu Hang's point of view was agreed by most people, and Lu Haoyu had no choice but not to speak, the only thing that is not clear now is why the sand and water can't leak, and what method is used to seal it under the raised floor, this problem is much more complicated than the problem of sound insulation.

Liu Hang returned to the middle of several people and led them towards the room on the left. (The left-hand side here is only for Liu Hang's personal position, as he walks towards the inside of the hexagonal room, not the exit.) ）
