The villain is trapped in the system and begs me to let him out [Moriarty who worries about the coun

The moment Du Ruoying saw the information, she was stunned. She finally understood the murderer's motive.

"Strange, if you want to take the blanket, you shouldn't go there." Keya's voice brought Du Ruoying back to her thoughts.

"What did you say?"

"I said," Keya was stunned, "Aunt Zhang seems to have gone the wrong way."

It was only then that Du Ruoying remembered that Aunt Zhang was going in the direction of the guest room - and Su Xiaochuan was right there now.

Could it be that William wanted to use Su Xiaochuan as bait to catch the murderer?

Thinking of this, Du Ruoying's heart sank.She immediately chased upstairs and ran straight to Su Xiaochuan's room, just as Aunt Zhang swung a knife at him, so she rushed over and knocked Aunt Zhang away.

Keya, who realized that something was wrong, rushed over immediately: "Aunt Zhang, it really is you, why did you do such a thing?"

Aunt Zhang realized that she could no longer hide the matter, so she calmed down. She frowned and smiled bitterly: "For Zecheng."

"More specifically, it's for the unjust case back then," Du Ruoying said. "Five years ago, there was a murder case here. Sister Keya, don't you remember it?"

"I... remember, I didn't expect you to know everything, so I don't need to hide it from you anymore." Keya's voice lowered, "Ah Cheng killed one of our fashion models——Lan Xuan, before she took the stage. A few days ago, he secretly went backstage and sprinkled phosphorous powder on her dress. After the fashion show started, the phosphorous powder burned under the high temperature of the spotlight, burning Lan Xuan to death. Ah Cheng was arrested in public because of resisting arrest. He poured the remaining phosphorous powder on himself and set himself on fire."

"He didn't kill that model at all!" Aunt Zhang yelled, "Although Ah Cheng is introverted, he would never do such a cruel thing. I have always believed that he must be innocent! Take a look at the place where Cheng works, maybe you can find out something, so I came here and found that something was wrong."

"Are you?"

"She is Zhang Zecheng's mother." Du Ruoying said.

"But..." Keya was still a little confused, "I met Ah Cheng's mother once, and I remember her surname is Li."

"Hehe, it's plastic surgery," Aunt Zhang said. "After Ah Cheng's incident, my child's father and I suffered unimaginable public opinion violence, lost our jobs, were ridiculed, and neighbor's children often came to smash us in the middle of the night. Window, life is difficult. So we moved away, got plastic surgery, changed our name and surname, thinking that we could start over, but it was not that simple. We knew that our son must have been wronged, so we spent all night and all night I couldn't sleep, and not long after, the child's father became depressed and went away, leaving me alone, so I followed other people's advice and came here."

The crowd fell silent.

"Facts have proved that I did not come in vain," Aunt Zhang sneered, "One night, when Lu Zhu and Wu Yeling drank too much, when I was helping them pack their supper, I heard them admit that it was their plan. Ah Cheng. They had planned to kill Lan Xuan a long time ago, and they had planned for a long time. They deliberately chose flammable fabrics for the suit that Lan Xuan was going to wear that day, and the way of putting it on and taking it off was also designed to be complicated and difficult. Before going on stage A few days ago, they gave Ah Cheng a bottle of glitter powder and asked Ah Cheng to pour it on Lan Xuan's clothes. I bought the same bottle as in the monitoring, and the bottle was indeed filled with phosphorous powder—but, that bottle was put by Lu Zhu to frame Ah Cheng.”

"It turned out to be like this..." Keya was stunned.

"Lu Zhu and the others thought that they could escape the punishment of the law by doing this, hehehehehe, they never thought that someone could punish them instead of the law."

"However, if you had recorded their conversation and reported them, the law would have punished them," Du Ruoying said.

"What's the use of that? Ah Cheng died unjustly, and he still used such a painful way... His father is gone, and they won't come back again," Aunt Zhang's eyes became empty, and her thoughts seemed to be deep Far and deep, "What's more, can you be convicted only by recording? Oh, I've heard people say that it's not that simple. They might use an excuse of 'drinking nonsense' to turn everything over. Rather than Confront this group of scumbags head-on, make them wary of me, and lose the opportunity to approach them from now on, why not—"

"Even so, Qinglan is innocent!" Keya said, "and Xiaochuan."

"Because Miss Wen Qinglan recognized you, that's right," Du Ruoying said, "I'm afraid that cheesecake is a flavor she knows."

"Yes," Aunt Zhang lowered her head, "Ah Cheng likes to eat sweets when he's working overtime, but he has a bad stomach and can't eat outside food, so I often make some pastries for him to take with him. Miss Wen Qinglan Said that after she was scolded and cried by Lu Zhu once, Ah Cheng shared the cheesecake he brought with her in order to comfort her, so she recognized me today." Her eyes suddenly became fierce again, "Recognized me After me, not only did she not support what I did, she even persuaded me to surrender myself!"

"Just because she persuaded you to surrender, you killed her?" Du Ruoying was stunned.

These words obviously angered Aunt Zhang. She threw Du Ruoying to the ground and raised the kitchen knife again: "I surrendered? Why should I surrender? They should surrender! Since the law is so unfair, what's the point of it?" Qualified to judge me! Anyone who persuades me to surrender should die! You should die too!"

Du Ruoying suppressed the trembling in her heart, looked directly at her and said, "You said that the law is not qualified to judge you, so what right do you have to sentence us to death!"

The blade stopped suddenly just a short distance from the eyes.

"While you hate the people who wronged your son, but at the same time wronged the innocent William with your own hands, what's the difference between you and Lu Zhu and the others?"

"Oh, you said that Mr. William is innocent? I'm afraid that's not the truth, right?" Aunt Zhang sneered, "Did someone give me something from that professor? It doesn't look like something innocent people would have."

Du Ruoying felt guilty for a moment, but she still pretended to be calm and said, "Then Wen Qinglan is always innocent, right? Su Xiaochuan is also innocent, right? Isn't it more right for you to swing a knife at them than the law?"

Seeing Aunt Zhang's hesitation, Keya quickly persuaded her: "Yeah, Ah Cheng definitely doesn't want you to do this kind of thing for him, and—" She hesitated and stopped her voice, as if she didn't know what to say next Should it be said or not.

"And what?"

"Besides, you shouldn't kill Qinglan just because it's for A-Cheng. These years, besides you, she is the one who cares most about A-Cheng's case. She has been secretly looking for the truth, trying to clear his grievances. "

"It turns out that she studied so many reasoning tricks to solve the mysteries of the year, not for interest." Du Ruoying understood.

"Why...she wants to do this?" Aunt Zhang seemed to be a little dubious.

"Because the relationship is very good," Du Ruoying guessed, "Then an introverted person is willing to share the cake made by his mother with Qinglan, so the relationship must be not shallow."

"It's a lover," Keya said, "Although we haven't been together for long, and I haven't told anyone, I can tell."

"Lover?!"

This astonishing fact makes Aunt Zhang feel like being struck by lightning——

She thought that everything she did was for her son, but she never imagined that she would kill the person he loved the most with her own hands.

"Then Ah Cheng...Ah Cheng, he will definitely not forgive me..."

She powerlessly put down the blade in her hand, and sat aside, as if her soul had been sucked out of her whole body, her eyes were empty, and she no longer wanted to resist.

"However, why do you still want to kill Xiaochuan? He should have nothing to do with Ah Cheng's case, right? Could he also pose a threat to you?" Du Ruoying asked.

"Almost," Aunt Zhang told Du Ruoying about eavesdropping on William's phone call. Seeing that Du Ruoying's face suddenly became serious, she explained, "Don't worry, I just put some in Mr. William's tea. It's just sleeping pills, he'll wake up in a while."

"I'm not worried about this..." Du Ruoying suddenly bit her lower lip tightly.

She knew exactly how difficult it was to pour William the medicine, but it was impossible for that guy to fall asleep so easily, he was clearly pretending.As for the phone call, it was obvious—

He wanted to borrow a knife to kill someone.

If we speculate a little further, maybe as early as the very beginning, William had already calculated such an ending, and the reason why he chose to endure all this silently was just pushing the boat along the way.

Du Ruoying suddenly felt extremely shuddering.

Why did William want to kill Su Xiaochuan, obviously...it was the first time we met!

Speaking of it, Aunt Zhang seems to have been mentioning "someone", "someone" suggested that she come here to find the truth, "someone" said that the recording alone could not convict Lu Zhu, "someone" could punish Lu Zhu instead of the law, and "someone" showed her William's profile...

Could it be that--

Du Ruoying was about to continue asking, but she saw Aunt Zhang twitching all over, and then fell to the ground, completely out of breath. In her pocket, a brown glass bottle filled with capsules rolled out slowly, with the words " Metformin Glibenclamide Capsules".

Death by electric shock, purple lips, cherry red skin all over the body, bitter almond smell in the mouth...

"It's cyanide poisoning." Du Ruoying was stunned, "But, how could this happen?"

"It must be because—" Su Xiaochuan got up from the ground weakly, "She feels remorse for the crimes she committed, so remorseful that she can't wait to kill herself."

In the evening, the mountain road became clear again, and the police also arrived. After surveying the scene and taking everyone's statements, they also ended this terrible serial murder case on the grounds that "the criminal committed suicide in fear of crime".

"Killing is like the flame of evil. Once it is ignited, it can only spread wildly." An unknown voice came from the ear, "No matter how legitimate the original reason is, it will sooner or later be out of control. The destructive heat will eventually engulf everything , innocent or not. Until the end, the arsonist himself is consumed."

"The arsonist himself was also devoured...?" Du Ruoying stared blankly at the flashing red and blue police lights outside the window, and subconsciously repeated the last sentence.

Yes, everything seems reasonable and sounds reasonable, but why, she still finds it unacceptable.

The cyanide was obviously hidden in Aunt Zhang's medicine in advance, and she took it shortly after lunch. Could it be that she had the idea of ​​suicide so early?It doesn't look like...

While the others were busy, Su Xiaochuan leaned over to William's side: "Hey, you are so cruel, I just help spread the word, you don't have to kill me if you don't want to make a deal, right?"

"Kill you? I don't understand what you're talking about. You're still alive and kicking." William said coldly.

"If it wasn't for Xiao Ruoying, I wouldn't be able to jump around, woo woo woo, you are so scary, I won't accept any more commissions related to you." He looked very aggrieved.

"Entrustment?" William smiled knowingly, "So that's the case, then can I also entrust you, and send a message back to your client."

"No!" Su Xiaochuan raised his arms, gave him a big cross, and then retreated, "From now on, I will never touch any entrustment related to you! Don't even think about entrusting me! Stay away from me !"

When I returned to the teacher's apartment, it was getting late, and Du Ruoying finally decided to talk to William about her thoughts: "This case is not right."

"Oh?"

"On the way back, I kept thinking that not only this case was wrong, but also the case five years ago." She said, "Phosphor powder that can burn under the spotlight must be mixed with white phosphorus, but white phosphorus It is a nationally controlled product. As fashion designers, how can they obtain such a large amount of controlled products? And they can also prepare a mixed phosphorus powder with a suitable ratio."

"Who knows?" William shrugged.

"Similarly, as an ordinary person who worked in a pastry shop, where did Aunt Zhang get the white phosphorus? How could she come up with such a complicated criminal method? Not only did she need to use professionally designed software, but also You also need to understand the salt spray test, and you must have a good understanding of the switchboard of the landline." Du Ruoying said, "There is also the alibi trick, which is actually very risky to use—after all, who knows you How big is the phone’s memory, if it’s too big to fill it up by shooting rubbish videos all night, wouldn’t her trick come to nothing? Could she check your phone’s information in advance?”

"Speaking of which, it's really some interesting discoveries," William suddenly smiled at her, "So what do Xiaoying think?"

"I don't think it's possible for her to have such a complex knowledge system and technical ability. Someone should have helped her plan the crime behind the scenes." Du Ruoying said, "And, judging from your reaction - it's Su Xiaochuan."

"Oh? My reaction?"

"Since he dares to plot against you, then kill him instead—is that what you think?"

"Student Xiaoying's reasoning ability is really getting better day by day," William applauded. "However, I still suggest that you learn more from your brother—in the absence of evidence, it is best not to talk about some things."

Du Ruoying was about to continue her defense, but a knock on the door interrupted their conversation. William went up to open the door and saw that the person who came was a student, holding a huge express box in his hand. The things in the box looked hard and very heavy. Shen.Du Ruoying remembered that student, who was taught by William in the math competition.

"Mr. William, your things."

"Thank you, the box is very heavy, thank you for your hard work."

"No hard work, no hard work." The other party smiled shyly, "Teacher, if there is nothing else, I will go back first."

"Well, pay attention to safety on the road."

"okay."

After the other party left, William moved the box back to his bedroom.

Taking a quick glance, Du Ruoying vaguely saw the word "white" on the sticker of the box: "Hey, did you buy something strange online again?"

However, William just chuckled twice: "It's a secret." Then he closed the bedroom door and locked the door lock.

This guy……

Du Ruoying looked away speechlessly. Inadvertently, the red high-heeled shoes on the shoe rack suddenly attracted her attention. She remembered those shoes, which were left by the special service lady he called.

She picked up the shoes curiously and looked at them. The leather texture was very good, and the color was bright and high-end. It was not cheap at first glance.He took out his phone and searched, and sure enough.

That little sister left in a hurry, so she left her shoes behind. Du Ruoying could barely accept this, but after all, it was such an expensive pair of shoes. After all these days, she didn't even come back to take them away?

Du Ruoying couldn't help but feel a little puzzled.

On the other side, after closing the door, William restrained his gentle expression.He put on his gloves and opened the carton. Suddenly, a black suitcase was revealed. He carefully unzipped the suitcase and opened the lid. Inside was the unconscious Mi Musha.

"Mimusa...is that the name, right?" William said softly, "I've let you rest for so long, next, it's time to have a good chat with me."
