Chapter 519 The Almost Perfect Secret Room
Conan frowned. He stared at the copper lock for a while, but the copper lock was still a copper lock, and there was nothing unusual. He shook his head and said in a daze, "I still can't see it."

Li Canghai smiled indifferently, and said: "Brother Nan can't see it because Brother Nan has fallen into an 'obstacle'. There is nothing abnormal about this copper lock itself. I said that this copper lock is just a tool to confuse us, and has no real substance. The role of sex. The murderer took great pains to arrange the scene into a perfect secret room. He almost thought of all possibilities, so he broke the lock cylinder. But this is precisely the most clever performance of the murderer, but he ignored the very important a little."

"Which point?" Conan asked.

"The door was locked with an iron chain, and the iron chain was intertwined through two copper rings. After being hit, the copper ring behind the door on the right was directly knocked off and hung on the iron chain. , Under such a situation where one side is stressed, the copper lock will only droop along with the iron chain, so how could the copper lock be broken and fly away?" Li Canghai asked rhetorically.

Conan's eyes lit up immediately, and he understood immediately, and he suddenly realized: "So that's the case! This is indeed a suspicious point!"

What Li Canghai said made everyone feel confused, except for Conan, everyone else was confused.

Conan explained: "In fact, the matter is very simple. After killing Hongmei, the murderer did not lock the door with a copper lock. Instead, he threw the copper lock on the ground and closed the door with an iron chain. After we were unable to push the door Sometimes, I always subconsciously think that the door is locked from the inside, especially after seeing the copper lock on the ground, I am even more convinced of this concept. The murderer took advantage of this and made us a fake Chamber of Secrets."

Zhang Wenyuan frowned and said: "Although what you said is reasonable, it doesn't explain anything. When you hit the door with force, it's hard to say that the cylinder of the copper lock won't break?"

Li Canghai nodded and said: "Yes, this is probably what the murderer never thought of. The murderer thought that when the door was knocked open, the copper lock would be broken, but he didn't expect to break the copper ring on the right side of the door. It was pulled down. And this is the only negligence of the murderer, if not for this negligence, I am afraid that this is really a perfect secret room murder case."

Zhang Wenyuan still shook his head, and he said: "Even if it is true as you said, the murderer set up a fake secret room, but this is unreasonable. If the door of the person who broke the door was only chained and not locked, the murderer arranged Are these worthless?"

"Yuanwai is right. This is indeed a bit risky. If someone discovers the clues, it will fall short. The member outsider can think of it, and the murderer can naturally think of it, but it is not difficult to solve this problem. As long as the person who broke the door is not someone else " Li Canghai looked at the masked man and said deeply.

Conan suddenly realized, he nodded and said: "Yes, as long as the murderer is the one who broke the door first, no one will find out the clues."

Zhang Wenyuan crossed his arms and recalled: "I remember that the person who broke the door first was...."

"That's right, the murderer who killed Hongmei was him, Yu Cheng'en!" Li Canghai stared at the masked man, and said deeply, "Aren't you afraid to take off the mask even now?"

As soon as this statement came out, everyone was astonished.

I saw the masked man slowly taking off the mask on his face, revealing a face that surprised everyone, who is it if it's not Yu Chengen?
Zhang Wenyuan stared blankly at Yu Chengen, he never thought that Yu Chengen was actually the murderer of Hongmei.

Yu Yanrou's face was also pale for a while, her shoulders trembled slightly, she bit her lips lightly, her eyes were full of worry.

Conan also shook his head and sighed again and again. Who would have thought that Yu Chengen, who has been enthusiastically helping them investigate the case, is actually the murderer?
Even Li Canghai was feeling sorry for a while. From the past few days of getting along, he could tell that Yu Chengen was a person with ideals and ambitions.

In several conversations, he expressed his worries about the Tang Dynasty, and even bluntly pointed out that An Lushan would rebel sooner or later, and he was indignant at Yang Guozhong and other treacherous officials for controlling the government.

To be honest, Li Canghai didn't want Yu Chengen to be the murderer very much, he even planned to recommend him to Cui Huan after the incident happened here.However, what he least expected to happen actually happened.

"Yu Cheng'en! You are a wolf-hearted bastard. I treat you more politely for the sake of Rou'er, but you killed my concubine? Say, why did you kill Hongmei?" Zhang Wenyuan was extremely angry, Pointing at Yu Chengen's nose, he roared angrily.

Yu Chengen was expressionless. He glanced at Zhang Wenyuan coldly, and hummed in a low voice, "I'm a beast? What are you?"

"You! I killed you!" Zhang Wenyuan roared angrily.

"Stop!" Yu Yanrou suddenly shouted anxiously.

"Rou'er, get out of the way! Although this guy is your elder brother, but he killed Hongmei, I will kill him to avenge Hongmei!" Zhang Wenyuan said angrily.

"Wait a minute!" Li Canghai glanced at Zhang Wenyuan, and said calmly, "If Yuanwai kills him, he will definitely regret it. What's more, even if you want to kill him, you have to wait for everything to be clarified before you do it, otherwise you will die soon." Aren't people very wronged?"

Zhang Wenyuan snorted, pointed at Yu Chengen and said viciously: "I will let you live a little longer! When everything is clear, I will kill you with my own hands!"

Li Canghai looked at Yu Chengen calmly, and said calmly, "Tell me, why did you kill Hongmei?"

Yu Chengen stared at Li Canghai, and suddenly laughed: "Brother Li, what you just said is really exciting, but what does it have to do with me? I didn't kill anyone."

Li Canghai sighed, and said regretfully, "Brother Yu, don't you admit it even now?"

"I didn't do it, why should I admit it? On the night of Hongmei's death, I was in the room all night, and this good time can prove it." Yu Chengen said indifferently.

Conan also frowned, and said: "Yes, this is indeed a suspicious point. You said that he killed people, but he was in the room all night and never went out. How can he kill people?"

"No, he went out." Li Canghai looked deeply at Yu Chengen and said, "You got drunk on purpose and let Liang Chen serve you. In this way, your alibi is also reasonable. Remember what I said , Did Hongmei die between midnight and early morning? But during this time, no one left the room, except you."

"Brother Li, did you make a mistake? I was drunk all night and didn't go anywhere. If you don't believe me, you can ask Liangchen." Yu Chengen said lightly.
