Chapter 518 Brass Lock
Li Canghai nodded, and said: "Well, let me reveal the true face of the murderer step by step! The victims of the three murder cases died in different ways. These three murder cases seem to be unrelated, but they are actually very serious. implicated."

"What's the connection? It goes without saying that Hongmei must have been killed by him, but Azhu and Juzi died at the hands of Ueda Takashi. Could it be that he and Ueda Takashi are accomplices?" Zhang Wenyuan asked with a frown.

"Ueda Takashi didn't kill Azhu, and he didn't kill Juzi. He was not the murderer. I will explain this to the members later on." Li Canghai said.

As soon as this remark came out, Conan and Zhang Wenyuan were extremely shocked at the same time, and both of them showed expressions of disbelief.

"Leaving aside the murderer, 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 the secret room murder?"

Li Canghai nodded, he smiled slightly, and said, "I have to thank Brother Nan, if Brother Nan hadn't suggested letting me go for a walk, I wouldn't have found the answer so quickly."

"Oh? Brother Li, please advise." Conan said seriously.

After pondering for a while, Li Canghai said: "Then let me start with Hongmei being killed. Everyone knows the cause of Hongmei's death. She was strangled to death by the murderer, and then hung on the beam to make a false appearance of suicide." The most puzzling thing about the whole case is that the doors and windows of the house were closed from the inside, and there was no sign of destruction. How did the murderer disappear after the murder?"

Everyone looked at Li Canghai with doubts in their eyes.

"The doors and windows are closed, and the door is also locked with iron chains from the inside. The murderer is like a ghost. After killing someone, he quietly floated away from the house without leaving any clues. This is really unbelievable. I thought about it for a long time. If you don't understand the key point, could the murderer be teleporting?" Conan asked with his brows furrowed.

Li Canghai smiled lightly and said, "Brother Nan's thinking is too complicated. The murderer doesn't know how to teleport or escape. He just used a little trick to deceive all of us."

"What does this mean?" Everyone was at a loss.

Li Canghai's eyes swept across the crowd, and said word by word: "Actually, there is no secret room at all. It is the room where the murderer swaggered out of the room after killing someone."

"How is this possible?" Conan exclaimed in disbelief: "I checked Hongmei's room at that time, all the windows were closed from the inside, and although the door was damaged, it was hung with iron chains. The copper lock was hit by a huge force and fell from the iron chain to the ground, all signs indicate that this is indeed a secret room! Brother Li, why do you say there is no secret room at all?"

Li Canghai nodded, and said: "That's right. At first I saw the copper lock and iron chain, and they were exactly as you imagined. I thought the murderer killed in the secret room and then disappeared in the secret room. But it's these Brass locks, iron chains, doors and windows influence our thinking and affect our judgment. There are two reasons why we think that the murderer disappeared in the secret room. It was found that the door of the room was locked from the inside. The second is the closed doors and windows in the room, as well as the copper locks that fell on the ground and the iron chains hanging from it."

After a pause, Li Canghai continued: "When we hear that the door of the house is closed, relevant conjectures will emerge in our subconscious mind, and when we see that the doors and windows in the house are indeed closed, as well as the copper lock and iron chain, we will The subconscious mind will become real, which makes us think that it is indeed a secret room. Then, such a picture will appear in our minds: the windows are closed, the door is connected with iron chains through the copper rings from the inside, And lock the brass lock."

"Are you saying that we were deceived? Could it be that the member is lying outside?" Conan asked suspiciously.

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

Li Canghai shook his head and said, "Yuanwai didn't lie to us, because even Yuanwai fell into the murderer's trap."

What he said made everyone more confused, and Conan scratched his ears and cheeks in anxiety, and hurriedly said: "Brother Li, don't be fooled, tell me what's going on?"

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

"Props? What props?" Conan thought for a while but couldn't figure out why.

"The so-called props are always in front of our eyes, which are the copper locks, iron chains, doors and windows I mentioned before." Li Canghai clapped his hands, and a servant hurried in with a bag and handed it to Li Canghai.

Li Canghai opened the bag and took out an iron chain with a copper ring and a broken copper lock from it. Seeing the puzzled expressions on everyone's faces, he explained: "After the murderer killed Hongmei, Lock all the windows, then pass the iron chain through the two copper rings inside the door, then walk out of the door, and pull the iron chain from the crack of the door outside to make the door closed. When the door is not completely closed, Wrap the iron chains around each other, leaving only a gap between the doors. In this way, the door is closed, thus forming a secret room that is locked from the inside."

Conan took a look at the iron chain, frowned slightly and said, "But, it doesn't make sense, even if the murderer buckled the iron chain on the door of the house, how did the copper lock lock it? You also said, After the murderer locked the door, there was only a gap left by one finger, such a narrow gap, how did the murderer lock the copper lock on the iron chain?"

Li Canghai picked up the copper lock, weighed it a few times, and said, "This is the most clever part of the murderer! Because this copper lock is not on the iron chain at all, but was thrown on the ground by the murderer beforehand!"

Conan's face changed for a while, and he seemed to have figured out the key point in an instant, and said in surprise: "It turned out to be like this! The murderer's method is really clever!"

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

"But, how did you discover this?" Conan asked.

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

"What clue?" Although Conan figured out the key point, he didn't see any flaws.

"That's the copper lock! The murderer presumptuously made a copper lock, so that we could think that Hongmei died in a secret room, but we didn't expect this to be the key point to reveal the whole case. The murderer left the copper lock on his own cleverness, nothing more than Wanting to prove that the door was indeed locked from the inside, the copper lock was also knocked off when the door was knocked open. In order to prevent everyone from suspecting, he broke the lock cylinder of the copper lock in advance to make a mistake because of being attacked. The impact, the sign of being broken by the iron chain. And it is precisely this that exposed this secret room." Li Canghai said while holding the copper lock.
