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

The screams came from the outside. Just between the east hall and the west hall, everyone rushed to them one after another. In the bushes behind a camphor tree, they found Wen Qinglan lying in a pool of blood. The man cuts the carotid artery.

Du Ruoying and Su Xiaochuan were the last to arrive. She noticed that Wen Qinglan was still breathing weakly, and immediately stepped forward to press the proximal end of the wound for her, and asked Keya, "Do you have any vascular clips?"

But Keya just shook her head helplessly: "Can ordinary clips be used?"

"No, it's better to press it with your hands."

Du Ruoying noticed that Wen Qinglan's hand moved slightly, and she watched in astonishment as Wen Qinglan slowly raised her hand, as if she wanted to gather her last strength to identify the murderer, but her hand was weak when she raised it halfway. The floor sank—she went into hemorrhagic shock.

Knowing that rescue has become an extravagant hope, Du Ruoying is still unwilling to give up: "Can you please ask 120 to dispatch a helicopter rescue? This will definitely not last!"

"I... I'll go and ask!" Aunt Zhang hurried back to the east hall after speaking.

Time has never been so long and difficult as it is now, and 1 minute is like a century.When Aunt Zhang finally came back, Wen Qinglan had completely stopped breathing.As for the 120 rescue helicopters, due to the shortage of the number, it was not possible to make an appointment after all.

Du Ruoying stared blankly at Qinglan's corpse, and her mind became a little dazed. She didn't understand why she had become like this in the blink of an eye when she was eating dessert together before.A human life has turned into a handful of fine sand between fingers, and we can only watch it go away, no matter how hard we try to keep it, it will be in vain.

But now is not the time to wallow in negativity, she must remain calm.

"Judging from the shape of the wound," she said during the autopsy, "the murderer swung a knife from the front and cut Miss Wen Qinglan's carotid artery at close range. It should be committed by an acquaintance, and this murder is different from the previous two. The method is very direct. No tricks were arranged, it may be an unexpected situation, and the murderer did not have any preparations in advance."

"No preparations? What does that mean?"

"It means that Ms. Wen Qinglan is probably not on the list of people the murderer originally planned to kill. Since the murderer wants William to be the scapegoat, he shouldn't kill at this point in time. Ms. Wen Qinglan may have discovered something that will have a negative impact on the murderer. Threatened, the murderer had to do this." Du Ruoying looked at Keya and the others, "I'm sorry to say such a thing, but the person who killed Miss Wen Qinglan couldn't be William, Xiaochuan and I were guarding He, the murderer can only be among the three of you."

"But I was on the phone with Party A," Keya said. "If you don't believe me, ask Party A. During our chat, he must have heard the screams."

"I... I was washing dishes in the kitchen." Aunt Zhang said.

"It can't be me," Carl said, "I was rushing to draft in the studio at the time, you can see the time column of my computer file."

"Unfortunately, none of these three can be used as an alibi." Du Ruoying said, "With the help of a Bluetooth headset, it is not impossible to kill someone while talking on the phone. If there is no second person to testify about washing dishes in the kitchen alone, It doesn’t explain anything either. As for computer files, as long as automatic saving is set in advance, the time bar is not a problem.”

"You mean, the murderer of this serial murder is actually among the three of us?" Keya's eyes widened in disbelief.

"You can't say that," Aunt Zhang said. "Maybe this murder is not the same case as the first two?"

"If we fight like this, we won't get any results. No matter who is the murderer," Keya glanced at Aunt Zhang warily. "I suggest that everyone stay together until the police come here. It's always safer."

"It's good for you to stay together. I have to catch up with the design draft, so I'll forget it." Carl said and left.

"How cunning, he is not the only one facing the deadline." Su Xiaochuan said, "Then I will go back to the guest room to catch up on the novel."

Keya looked at Du Ruoying expectantly, but unexpectedly she also disagreed with Keya's proposal: "Sorry, I have to continue looking for clues to the case. As Aunt Zhang said, although William was cleared in the third case, but The evidence in the first two cases still points to him. If all the mysteries are not solved by evening, I fear the police will still take him away."

Ke Ya's proposal was completely dismissed, but she still expressed her understanding to Du Ruoying, and asked Aunt Zhang to release William so as to protect Du Ruoying who was investigating the case.

Accompanied by William, Du Ruoying went to the kitchen first.

"By the way, when you were in the warehouse, what were you and Su Xiaochuan talking about?" She asked while checking the refrigerator, and found that the refrigerator was not broken, and the temperature control panel was also normal.

"It's nothing, just a personal matter," William said.

"..." Well, she knew she couldn't ask anything.

Then, the two arrived at the door of Wu Yeling's guest room. Du Ruoying searched carefully on the wooden threshold, and found a few traces of wear and tear as thin as hair. They looked very new.

"Sure enough, the key was pulled in with a fishing line." She murmured.

Of course William knew what she was referring to, so he said: "With only fishing line, there is no way to drag the key to the corner of the bathroom. It is so empty."

She raised her eyes and saw the expression on his face, knowing that he was testing herself again, so she replied nonchalantly: "It wasn't empty at that time, the murderer had frozen a piece of ice in the refrigerator in advance - the size of a fist should be enough, The ice was fixed to the floor in the corner of the bathroom with an adhesive such as liquid nitrogen, providing a turning point for the fishing line. Then the murderer turned on the hot water in the shower head, went out and locked the door, threaded the key into the fishing line, and yanked it out. The location where the ice was, and then the thread was untied and recovered. Finally, the ice cube melted quickly under the action of hot water, and the crime tools disappeared completely."

"Sounds very interesting, but unfortunately there is no proof, student Xiaoying." William said.

"...Yes, I have no evidence." Du Ruoying was obviously hit by a pain point, "But I must have guessed correctly, so that I can explain why the kitchen refrigerator froze the mousse so hard even though it was not broken, it must be the murderer I deliberately lowered the temperature when I was making the crime tools in the middle of the night." She was stunned for a moment, "Could it be that Wen Qinglan thought of this, that's why she was killed by the murderer... No, no, just thinking of this, the murderer It shouldn't be a threat, she must have found a more deadly clue."

Du Ruoying's eyes suddenly fell on the landline in Wu Yeling's room, as if she had thought of something, she called Bai Qirun.

"Qi Run, I have a question for you. If A calls B from the landline in the same villa, can it be pretended to be C...ah, you mean the exchange? I don't know...wait, don't hang up , I'll go ask." Then she pulled William together to find Aunt Zhang, and learned that the switch was in the equipment room, so they went to the equipment room again.

"The switch model is TCWS848-A1." After finding the switch, Du Ruoying told Bai Qirun. [1]

"It turned out to be that one," Bai Qirun said, "I remember that it can customize the extension number. If the interface is exchanged by direct plugging and unplugging, and then replaced after the work, it should be able to complete the operation you said. To verify This conjecture is also simple - the wires of the switch and the interface are generally covered with dust, you can see if there are two wires that have been rubbed off with a little dust."

"Ah, indeed."

"That's definitely true."

"Can this kind of operation be traced to detailed historical records?"

"It's hard to check. After all, they share the same host number. Why don't you try the playback function on those extensions, or check the local call records? If the other party's anti-detection capabilities are strong enough to deal with these in advance, then It's gone."

"Sure enough..." Du Ruoying sighed in disappointment.

At this time, William on the side suddenly patted her on the shoulder: "This is not far from the bathroom, and there is only a kitchen in the middle. I just want to go. Just stay here and wait for me, don't run around."

Du Ruoying looked around, and couldn't help feeling a little scared: "Is it just this time?"

"Don't worry, if you haven't found conclusive evidence, the murderer won't do anything to you." He smiled teasingly, "Of course, if you're really scared, you can go to the bathroom with me."

"...Who wants to go with you?" She waved her hands in disgust, "Go and come back soon."

After William left, Du Ruoying called Du Ruoxian again: "Brother, can you help me find a case file - the person in the case is Zhang Zecheng, a fashion designer."

On the other side, as soon as William closed the bathroom door, he called Su Xiaochuan: "I want to know exactly what the transaction content you mentioned is."

"Oh, you finally figured it out?"

"Well, I figured it out."

"It's actually very simple. I will give you all the information such as the identity of the murderer, the method of crime, and the evidence of conviction. They are enough to prove your innocence." On the other end of the phone, Su Xiaochuan's tone sounded very relaxed.

"It seems that Mr. Su not only figured out the method of committing the three cases and the identity of the murderer, but also found the evidence?"

"You can understand that."

"Then why don't you just announce it to everyone?"

"Hahahaha, what nonsense are you talking about? This is a deal between me and you. Of course it's 'one-handed person, one-handed information'! Do you think I will give it for nothing?"

"Can't I give it to you for free...?" William smiled strangely, "You are right, but I still need some time to prepare, otherwise—it is 02:30 now, and I will arrive at you at three o'clock later. Come in the room and we'll talk about it in detail."

At the same time, in the corridor just one wall away from William, a figure with a ferocious face had already listened to their entire conversation.

In the afternoon, the sunlight outside was dazzling, but the room was kept cool under the temperature control of the air conditioner.

After completing all the survey work, Du Ruoying and William returned to the living room. Accompanied by Keya who was restless, Aunt Zhang brought them two cups of black tea, and then sat down together. The four of them sat together silently. .

William casually flipped through the magazine at hand while drinking the freshly brewed black tea leisurely.Du Ruoying kept staring at the phone, she was waiting for Du Ruoxian to send the information.

The clock in the living room turned slowly, and it was almost three o'clock. However, at some point, William dozed off uncharacteristically, and couldn't wake up no matter how much he yelled.This made Du Ruoying feel something was wrong.

"Oh, why did Mr. William fall asleep here? It's so easy to catch a cold. I'll go get him a blanket and cover him." Aunt Zhang went upstairs after saying that.

However, the moment she turned her back to look away from everyone, a treacherous smile suddenly appeared on the corner of her mouth.

"Just take a good night's sleep under the effect of the sleeping pills of black tea, Mr. William, but when you wake up, the person who can prove your innocence will no longer be in this world."

At the same time, Du Ruoying's mobile phone finally received news from Du Ruoxian, so she had no choice but to temporarily leave William behind and check the information.

No one noticed that William's eyes had quietly opened a slit, and his gaze followed Aunt Zhang until she disappeared around the corner of the upstairs corridor.

"I don't know if Mr. Su's friend who loves to play chess has ever played Reversi," William sneered and thought to himself, "When a black chess is surrounded by four white chess, it will immediately turn against each other and become white. Fang. The rules of the game make me very interesting. Since you like to call yourself a master chess player so much, how about a little taste of being counter-killed by your own pieces?"

On the other side, accompanied by a slight electrical crackle, Su Xiaochuan fell softly at the door of the guest room, and in front of him was Aunt Zhang holding an electric shock baton.

She took out a gleaming kitchen knife from behind, and then stabbed Su Xiaochuan fiercely.
