Li Canghai nodded and said, "In this way, let me reveal the true face of the murderer to everyone step by step!" The victims of the three murders died under different methods, and these three murders seem to be unrelated, but in fact they are very involved. ”

"What's at stake? Needless to say, Hongmei must have been killed by him, but Azhu and Tangerine died at the hands of Ueda Takashi, could it be that he and Ueda Takashi were accomplices? Zhang Wenyuan frowned and asked.

"Ueda Takashi didn't kill Aju, nor did he kill Tachibana, he wasn't the murderer. I'll explain this to the outside later. Li Canghai said.

As soon as these words came out, Conan and Zhang Wenyuan were extremely shocked at the same time, and the two of them showed expressions of disbelief.

"Leaving the murderer aside, everyone must be as confused as I am about the murderer's killing methods, right? Then let me show you the murderer's killing methods one by one. Li Canghai said lightly.

Conan said in surprise: "Brother Li, have you solved the mystery of murder in the closed room?" ”

Li Canghai nodded, he smiled slightly, and said, "Thank you Brother Nan, if it wasn't for Brother Nan's suggestion to let me go out for a walk, I wouldn't have found the answer so quickly." ”

"Oh? Please ask Brother Li for advice. Conan said seriously.

After Li Canghai pondered for a while, he said: "Then I'll start with Hongmei's killing, everyone knows the cause of Hongmei's death, she was strangled to death by the murderer, and then hung on the beam of the house, making a false suicide. The most confusing thing about the whole case is that the doors and windows of the house are closed from the inside, and there is no sign of damage. How did the murderer disappear after the murder? ”

Everyone looked at Li Canghai with doubts in their eyes.

"The doors and windows were closed, and the doors were chained from the inside, and the murderer was like a ghost, and after killing someone, he quietly drifted away from the house, leaving no trace, which is really incredible. I've been thinking about it for a long time, but I can't figure out the key, could the murderer teleport? Conan asked, frowning.

Li Canghai smiled faintly and said, "Brother Nan's thinking is too complicated, the murderer doesn't teleport at all, and he won't escape at all, he just used a little trick to deceive all of us." ”

"What does that mean?" Everyone was confused.

Li Canghai's eyes swept over everyone, and he said word by word: "Actually, there is no secret room at all. After the murderer killed someone, he swaggered out of the room through the door. ”

"How is this possible?" Conan exclaimed in disbelief: "I checked Hongmei's room at the time, all the windows were closed from the inside, and although the door was broken, there were iron chains, and the copper lock was hit with great force, and all signs showed that this was indeed a secret room!" Brother Li, why do you say that there is no secret room at all? ”

Li Canghai nodded and said, "Yes, at first I saw the copper locks and iron chains, and they were the same as you thought, thinking that the murderer was killing people in the secret room, and then disappeared in the secret room." But it is these copper locks, iron chains, doors and windows that control our thoughts and affect our judgment. There are two reasons why we think that the murderer disappeared in the secret room, one is that the outsider said that when he arrived, he found that the door was locked from the inside. The second is the closed doors and windows in the room, as well as the copper locks and hanging chains that fall on the ground. ”

After a pause, Li Canghai continued: "When we hear that the door is closed, relevant conjectures will appear in our subconscious, and when we see that the doors and windows in the house are indeed closed, and the copper locks and chains, our subconscious will become real, and the truth makes us think that it is indeed a secret room." Then we have in our minds the image of the windows being closed and the doors of the house being chained through the brass rings from the inside and locked. ”

"You're saying we've been deceived? Is it a lie on the outside? Conan asked, confused.

"Nonsense! How could I lie to you? At that time, the doors and windows were indeed locked, and it took a lot of effort to break the door open. Zhang Wenyuan glared at Conan and said angrily.

Li Canghai shook his head and said: "The staff members didn't lie to us, because even the staff members fell into the murderer's hands. ”

When he said this, everyone was even more confused, and Conan was even more anxious to scratch his ears and cheeks, and hurriedly said: "Brother Li, don't sell it, tell me what's going on?" ”

Li Canghai smiled slightly and said, "Actually, the murderer just used some props to make us mistakenly think that Hongmei died in the secret room. ”

"Props? What props? Conan thought about it for a while, but couldn't come up with a reason.

"The so-called props have always been in front of us, which are the copper locks, chains, doors and windows I mentioned earlier." Li Canghai clapped his hands, and a family member hurriedly walked in with a burden and handed it to Li Canghai.

Li Canghai opened the baggage, took out an iron chain with a copper ring hanging from it, and a broken copper lock, he looked at the puzzled expressions of everyone, and explained: "After killing Hongmei, the murderer locked all the windows, and then used the iron chain to pass through the two copper rings inside the door, and then walked out of the door, pulled up the iron chain from the crack in the door outside, and closed the door. When the door is not completely closed, the chains are wrapped around each other, leaving only a gap in the door. In this way, the door was closed, and a secret room was formed that was locked from the inside. ”

Conan looked at it with the chain, frowned slightly, and said: "But, this doesn't make sense, even if the murderer locked the chain outside the door, how did this copper lock lock?" You also said that after the murderer locked the door, only a finger was left behind, such a narrow gap, how did the murderer lock the copper lock on the iron chain? ”

Li Canghai picked up the copper lock, slid it a few times, and said, "This is the most clever thing about the murderer!" Because this bronze lock was not on the chain at all, but was thrown to the ground by the murderer beforehand! ”

Conan's face changed for a while, he seemed to have figured out the key in an instant, and said in surprise: "That's the case!" The murderer's methods are really clever! ”

Seeing that Conan figured out the key, Li Canghai nodded approvingly.

"But how did you find out?" Conan asked.

"It's still these props. The murderer used these props to make a secret room for us, but he didn't expect that it was these props that left us clues. "Li Canghai.

"What clues?" Although Conan figured out the key to it, he didn't see any flaws.

"It's this copper lock! The murderer self-righteously made a copper lock so that we thought that Hongmei died in the secret room, but we didn't expect that this was the key point in revealing the whole case. The murderer cleverly left the copper lock, just to prove that the door was indeed locked from the inside, and the copper lock was also knocked off when the door was opened. And it is precisely this point that exposes this secret room. Li Canghai said with the copper lock in his hand. (To be continued.) )
