"Door locks." Meng Wu said lightly, "I found that none of the locks in their house are the same, which is a bit unreasonable. ”

"Maybe it's just a change of door, that's why it's this situation." Zheng Hanfei thought for a while, and answered for enlightenment, "Didn't Village Chief Zhongxian say that the doors of Zhongming, Yu Haobu and Jiang Duxing had just been replaced, so the style of the door lock Village Chief Zhongxian may not have cared about it, or that was what they requested, let's ask Village Chief Zhongxian about this matter later?" Let's go to Zhong Ming's room first, maybe he might know about the door lock. ”

"Let's do it first." Meng Wu couldn't think of it for the time being, so he had to put this question aside, and followed Zheng Hanfei into Zhong Ming's room, and at the same time, Yu Haobu and Huo Guojia also returned to Zheng Hanfei and Meng Wu's room to standby, and then Zhong Ming walked out with an unhappy face, and when he saw the two of them walking into his room, a trace of disgust flashed in his eyes, and he walked back to his room.

"I was lying in bed studying the mermaid treasure." Zhong Ming pointed to the messy big bed, Zheng Hanfei really had nothing to say about it, although the bed was very messy and dirty, Zheng Hanfei could still see a few pieces of paper on the bed, a notebook and pens of various colors, Zheng Hanfei picked up a piece of paper, which happened to be written on the poem of the mermaid's calligraphy and painting, and a detailed analysis of the poem was written on the paper, it seemed that Zhong Ming had indeed worked this mermaid treasure.

Door locks are different again. While observing the room, Meng Wu glanced at the door, and found that the doorknob was actually round, and the door lock was on the round handle, which was a button type, and the door could be locked as long as it was pressed lightly, but the door could still be opened from the inside after the door was locked, as long as the handle was turned, but the door lock would also open, and it would not be locked because the door was closed again, and if you wanted to open the locked door from the outside, you must have a key.

"Is this what you asked for the lock on the door?" Meng Wu couldn't bear the doubts in his heart, and asked Zhong Ming out loud, "Or did the village chief Zhongxian get it for you casually." ”

"yes." Zhong Ming looked at Meng Wu with an idiotic eye, and said disdainfully, "Not only mine, but the door lock of Yu Haobu's room where Jiang Duxing is awakened is also their request, Yu Haobu and I both want to be convenient and fast, and open and close the door lock at any time, while Jiang Duxing wants to rotate, it is better to lock two more, saying that this will make him feel safer when he sleeps." If the old man had decided on his own, I wouldn't have stayed in this room! ”

"What about the other rooms?" Meng Wucai didn't care what kind of eyes Zhong Ming looked at him, and continued to ask, "Did Zhong Xian arrange the other rooms himself?" It's like our room and Niu Zhen and Huo Guojia's room. ”

"I don't know." Zhong Ming shook his head, shrugged his shoulders, and said an answer that made Meng Wu extremely disappointed, "You should ask the old man specifically, but as far as I guess, the door lock of your room should be the same, because we didn't ask for anything in your room, but I'm not sure." Okay, that's all I have to say, goodbye. ”

"Wait!" Zheng Hanfei stopped Zhong Ming, who turned around and walked to the door, hesitated for a moment, and finally said the doubts in his heart, "Although this is your private matter, I shouldn't ask more, but I still want to know, what happened between you and Village Chief Zhongxian?" Why don't you recognize him as a grandfather, never give him a good face, and even call him an old man. ”

"He doesn't deserve to be my grandfather." Zhong Ming stopped, his body trembled slightly, and his voice was extremely cold, "You can ask him, my grandmother, how did he die!" ”

……

"So he's still struggling about it!" Zhong Xian sighed and said slowly, "My wife's death did have some reasons for me, that was ten years ago, after the tsunami, I and the villagers were busy rebuilding the village, and suddenly heard a beautiful song from home, that is, the song of the mermaid, at that time I suddenly felt some uneasiness in my heart, so I hurriedly went back and found that my wife had fallen in a pool of blood. ”

"What was the cause of death?" Hearing that Grandma Zhongming died like this, Zheng Hanfei and Meng Wu both felt that this matter was not as simple as they imagined.

"Bleeding too much." Zhong Xian continued, "The body was found in the bathroom, according to the police, my wife is likely to slip in the bath, and her head hit the bathtub hard, and my wife's legs are not good, and there are basically people to accompany her in the bath, and I can't figure out why she took a bath by herself at that time, so I think that her death was done by a mermaid, and in order to retaliate for not keeping the mermaid calligraphy and painting strictly." ”

"Then these are the paper money you burned for her at the time of the crime?" Zheng Hanfei picked up the trash can, looked at the large amount of paper ash inside, couldn't help frowning, and asked, "You actually burned so much?" ”

"yes!" Zhong Xian said, "I hope my wife will live a little better in another time, unlike here, where she was killed by a mermaid." ”

"Village Chief Zhongxian, I want to ask you, did the locks on the doors of your grandson and his two friends' rooms be changed according to their request?" Meng Wu first glanced at the door lock of Zhongxian's room, and found that the doorknob and door lock were basically the same as theirs, so he remembered his question and hurriedly said, "Except for the different door locks in their three rooms, are the door locks in the rest of the rooms the same?" ”

"yes!" Zhong Xian nodded and said: "The door locks of the ten rooms on the second floor were the same before, and then Xiao Ming and his friends asked for it, so I replaced them with new doors and new locks, and at the same time, I also felt that the doors of other rooms should also be replaced, so I put up a few more doors, but they haven't been shipped yet, so the doors of your rooms have not been replaced for the time being." ”

"That's it......" Meng Wu lowered his head, and suddenly he saw a thread coming out of his sleeve, and wanted to pull it off, just the moment he held the thread, a spiritual light flashed through his mind, and the fog suddenly dissipated, he raised his head suddenly, looked at Zhong Xian, and asked: "Village Chief Zhong Xian, do you have any thin thread here, preferably cotton thread?" ”

"Yes, there's a lot of them in the warehouse." Zhong Xian's brain couldn't react, and he replied subconsciously.

"Does the warehouse usually lock the door?"

"No, there is nothing valuable in the warehouse, and besides, I haven't cultivated ......" Before he finished speaking, Zhong Xian heard Meng Wu say to go to the warehouse, and then heard the door slam open, and there was a bang slammed shut, leaving a dazed Zhong Xian sitting on the sofa, he didn't understand why Meng Wu became so anxious and frizzy.

Crunch! Meng Wu opened the door of the warehouse, rummaging through the boxes and cabinets to find the thin line, Zheng Hanfei didn't know why Meng Wu was so anxious, but he knew that Meng Wu must have his reason for doing this, so he decided to help him and began to search with him, and finally, Meng Wu found a pile of fine cotton threads in the corner of the warehouse, and the corners of his mouth slowly hooked a trace of arc.

"Sure enough, but the warehouse is open, which means that everyone on the second floor is suspected of committing a crime." Meng Wu picked up two long thin threads and muttered, "None of them have an alibi, everyone can lie, and more importantly, what is the murderer's motive for killing Jiang Duxing?" ”

"What's wrong? Could it be ......" Zheng Hanfei recalled the scene where he handled the case, he suddenly realized something, and said with some surprise, "You have already uncovered the mystery of the secret room?" Who is the murderer? ”

"To be precise, the light has solved the mystery of the secret room, and the true face of the murderer is still in the fog." Meng Wu corrected, "I won't reason until I find the murderer, otherwise I would have asked everyone to come over and reveal who the murderer is." ”

"How did the Chamber of Secrets come to be?" Zheng Hanfei asked, after all, Zheng Hanfei had been struggling with the testimony of all the suspects and the disappeared murder weapon so far, and he didn't have any clue about the secret room, so he simply listened to Mengwu's reasoning.

"The key to the formation of this secret room is to rely on two points." Mengwu didn't hide it, both of them were detectives, and it wasn't a problem to discuss with each other, so he stretched out two fingers and began to reason, "First, it is the special door lock of Jiang Duxing's door, and second, it is the fine wool in my hand, these two points are indispensable, and the murderer also made the secret room because of these two points, creating the illusion that the mermaid killed Jiang Duxing, and also used the mermaid's song to cause everyone to fear." ”

"Door locks...... ......"Zheng Hanfei pinched his chin, in Jiang Duxing's room, although he didn't pay much attention to the door lock, he still glanced at it a few times inadvertently, and he still had a general appearance in his mind, and according to the two key points that Meng Wu said, he vaguely knew how the secret room was formed.

"Looks like you already have the answer." Meng Wu looked at the somewhat messy warehouse and said, "This technique is indescribable, let's go to Jiang Duxing's room, and I'll show you it." But before that, let's clean up the warehouse so that the village chief doesn't talk about us. ”

"No problem." Zheng Hanfei readily agreed, tidied up the warehouse with Meng Wu, and when everything was done, he left the warehouse, put on gloves, and walked into Jiang Duxing's room, he wanted to see if there was any difference between Meng Wu's methods and what he thought.
