Yu Chengen's face was ugly for a while, and his face trembled involuntarily.

Li Canghai stared at Yu Chengen and sighed: "Brother Yu, don't you still admit it?" ”

As soon as these words came out, everyone was stunned.

"You...... What did you say? He...... He's my son? At this time, even if Zhang Wenyuan was stupid, he could guess the meaning of Li Canghai's words, he looked at Yu Chengen in a daze, and his face was full of astonishment.

Everyone's eyes stopped on Yu Chengen.

Yu Chengen didn't care about other people's eyes, but let out a long sigh, stared at Li Canghai, and said with a wry smile: "Brother Li, you're right. I killed them all. Originally, I thought that everything would go well, but I didn't expect it to hide from Brother Li's eyes. ”

"So, you...... Are you really my son? Zhang Wenyuan was short of breath, and his body kept trembling and looked at Yu Chengen.

Yu Chengen didn't look at him, his eyes were full of disgust, as if he would live ten years less if he looked at Zhang Wenyuan more.

In just a few days, I didn't expect Brother Li to not only find out the truth of the three murders, but also find out what happened back then. Cheng En really admires the five-body throw, I really want to know, how did Brother Li suspect me? I think I've done it perfectly, almost seamlessly, so why are there so many flaws? Yu Chengen stared at Li Canghai and asked.

Li Canghai stared at him, his eyes were full of pity, he sighed, and said, "You are very smart, so you have designed everything." After you kill Hongmei, you disguise it as a suicide, but you ignore the fact that if a person commits suicide, why should he lock the door? Actually, I never suspected you before, until I thought of prompting killing, and I thought of Mei Lan Zhuju. ”

Li Canghai found four poems from the poems written by Hongmei, and said: "These are the poems on the four paintings copied by Hongmei, and I didn't care about it at first. It wasn't until I discovered that these poems were copied from several paintings that I associated the murder with the events of the past. Later, Brother Nan found out about Feng Niang's incident back then, and I deduced that this was the motive for the killing. And this is what really makes me doubt you. ”

Li Canghai took out a key from his sleeve and sighed, "This is the key you found from Hongmei's room when you were investigating Hongmei's killing. After I found out that Hongmei did not commit suicide, but that he killed him, you deliberately suggested that the murderer might have left the key at the scene, trying to disturb my investigative thinking, and after that, you did find a key. At that time, I didn't figure out the murder in the locked room, because I didn't think it was strange, but I trusted you. It wasn't until I figured out the murder in the locked room that I got my suspicions on you. ”

"Oh? I would like to hear about it. Yu Chengen's expression was calm.

Li Canghai said: "You used iron chains and copper locks to create a psychological secret room for us, just to make us think that Hongmei committed suicide." Since Hongmei was going to commit suicide, why did she deliberately throw the key in the corner after locking the door? Isn't that redundant? What's more, Brother Nan also checked the scene before and didn't find any key, but you found the key, which has to make me suspicious. ”

Speaking of this, Li Canghai sighed and said, "Actually, even now, I only found out the evidence that you killed Hongmei and Tangerine, as for Ah Zhu, I only want to understand your killing methods, and there is no direct evidence to prove that you killed him." ”

"It's rare for Brother Li to be so honest, then I have nothing to hide, Azhu was indeed killed by me. I told Ah Zhu to let her stand at the door of the room at the time of the unitary, facing the direction of the bamboo forest, as long as she was sincere, she could be forgiven for the wrong things she had done in the past. As for the method of killing her, it is exactly as you say. I set up a bamboo crossbow in the bamboo forest in advance, and then used the calculated ice cubes to buckle the mechanism, and when the hour came, the mechanism was activated, and I successfully killed Azhu. Yu Chengen said expressionlessly.

Conan frowned and asked, "This method is too risky, how do you know that Azhu will definitely open the door at the unitary time?" If she doesn't do what you think, won't the plan fall short? ”

Yu Chengen snorted and said indifferently: "She will definitely open the door, because Hongmei is dead, and she knows why Hongmei died." She was afraid that what had happened back then would be exposed, and she was uneasy, so she would definitely open the door and hope for forgiveness. In fact, even if it fails, it doesn't matter much. As Brother Li said before, these things are inconspicuous things, even if they fail, no one will think that this is a murder weapon, and I can find another way to kill her again. ”

Speaking of this, Yu Chengen clenched his hands into fists, laughed with a hideous face: "Even I didn't expect that the plan would go so smoothly, this is all my mother's spirit in the sky to bless me!" That's why I killed her so smoothly! ”

"What about the red plum?" Conan asked.

"Red plum? It's even easier to kill her. Yu Chengen squinted his eyes and sneered: "After I stunned Liangchen that night, I took the 'Aoxue Hanmeitu' to find it." Sure enough, when she saw 'Aoxue Hanmeitu', her face changed greatly, and I took the opportunity to strangle her to death with a white silk! It's just that I didn't expect that Hongmei would leave so many clues about me before she died, which was really beyond my expectations. ”

"Why did you frame Takashi Ueda?" Conan asked with a frown.

"After killing Hongmei, I originally thought that you would think it was a suicide, but I didn't expect Brother Li's eyes to be like a torch, and he actually found the clue and thought that someone killed Hongmei. Later, I learned that Takashi Ueda had committed adultery with Takashi, so I calculated it and indexed it to him. I left him a note asking him to go to Hongmei's room to steal the hint for the next person I was going to kill. Later, I put a laxative in his meal to make him have a seizure when Aju died, so that he naturally became a murderer. As for the orange ......, what Brother Li said is not wrong at all, I will stun the two of them first, and then move Ueda Takashi to the garden, and when you arrive, I will kill her with a dagger. In this way, Ueda Takashi is also at a loss for words. ”

When Yu Chengen said this, he gritted his teeth, and his eyes exuded a chilling cold light that made people palpitate.

"So, you came to the Zhang family to take revenge?" Li Canghai stared at him and asked with a sigh.

Yu Chengen's face suddenly became sad, but the hatred in his eyes became more and more intense.

"I was raised by Aunt Yu since I was a child, I always thought that I was an orphan without a father and mother, but Aunt Yu treated me really well, she raised me as an adult, and asked my husband to teach me to read and write, so that I can be a person who stands up to the sky. It is precisely because of this that I was accepted as an apprentice by my mentor and learned calligraphy from my mentor. Two months ago, I was traveling in Chang'an with my teacher, but I suddenly received a letter from Rou'er, saying that Aunt Yu was seriously ill and asked me to rush back to Yangzhou.
