After Yu Fan finished speaking, the air froze for a few seconds. Everybody, you look at me, I look at you.

Only Yu Fan and Zhang Shengqian looked at each other tightly.

Zhang Shengqian's expression slowly darkened.

Suddenly, Zhang Shengqian rose up and flew towards Yu Fan to snatch the screwdriver from Yu Fan's hand!

Chen Jieyang was shocked: "Old Yu, be careful!! ”

Yu Fan was also stunned by this scene, and instinctively took a few steps back. But the speed of retreat was far less than the speed at which Zhang Shengqian pounced.

said that it was too late and that it was fast, Chen Jieyang flew up from outside the door and kicked Zhang Shengqian, who was rushing towards Yu Fan, to the ground. If it's a few tenths of a second late, the consequences will be unimaginable.

Chen Jiaoyang's colleagues also rushed back to the room and subdued Zhang Shengqian in two clicks. Zhang Shengqian didn't do any struggle.

Chen Jieyang scolded angrily: "Boy, what do you want to do? Assault on the police? ”

Zhang Shengqian quibbled: "No, I just want to see that screwdriver." ”

Yu Fan was scared out of a cold sweat just now, took two deep breaths, and calmed down. Yu Fan hadn't encountered this kind of thing for a long time, and suddenly felt a little excited and funny, so he joked to Chen Jieyang: "Old Chen, how can there be a battle link here?" That's not how the script is written, is it? ”

Then he immediately became serious: "Zhang Shengqian, you don't have to quibble, you are the one who pretends to be a ghost in Beiqiaogou Village, and you are the one who sabotaged the monitoring and leaked ferric chloride, right?" ”

Zhang Shengqian continued to pretend: "I don't know what you're talking about? I was on duty last night. “

Yu Fan said righteously: "Then how do you explain why the soles of your shoes are blue?" ”

Zhang Shengqian looked puzzled: "What are you talking about?" ”

Yu Fan took out a shoe of Zhang Shengqian from under Zhang Shengqian's bed, raised it and showed it to everyone, only to see that there were faint blue traces in the gap between the soles.

Yu Fan said quietly: "Lokar's law of material exchange, where there is contact between objects, there will be a transfer of matter, and the target object will take some matter away from the source object, and at the same time, it will also leave some of its own matter on the source object. The first time we went to that small courtyard of your stronghold in Beiqiaogou, you had already cleaned up the place very clean in advance, and indeed left no clues. But you shouldn't have provoked our people's police, maybe you think we found this stronghold too quickly, and after we left, your anxiety and worry made you return to this small courtyard again, and put on the strange illusion of a blood sacrifice to the whole village, trying to create public opinion to scare us away and drive us away. But because of your anxiety, your plans have been flawed, and the last time we were leaving, I sprinkled a little anhydrous copper sulphate powder on the floor of that house, which was not easily noticed by the dust on the dry winter months. But this time you returned to the scene and took them with you without knowing it! This shoe of yours must be the one you wore to the scene the next day, right? ”

Yu Fan paused, poured a bottle of water on the table to the sole of his shoe, and the blue color became more conspicuous.

Yu Fan continued: "Anhydrous copper sulfate is originally a gray or white solid, but after absorbing water, it becomes blue copper sulfate pentahydrate. Now how do you explain where the anhydrous copper sulphate in the soles of your shoes comes from? Sewage treatment plants shouldn't use anhydrous copper sulfate, right? ”

Zhang Shengqian lowered his head and thought frantically, trying to find a quibble countermeasure.

Yu Fan stared at Zhang Shengqian with his eyes, and said slowly: "Actually, we have met, right?" ”

Everyone present was shocked again. Zhang Shengqian lowered his head lower, not daring to look directly into Yu Fan's eyes, his hair drooped down, and he couldn't see his expression.

Chen Jieyang was worried that this guy still liked to play tricks, so he moved two steps closer to Yu Fan to protect Yu Fan. Suddenly, Chen Jieyang himself remembered something: "Yes, yes, I mean it's a little familiar, a few days ago we smashed the pyramid scheme organization of Master Jielu, you seem to be one of the listeners inside?" ”

Yu Fan: "Now it seems that he is not as simple as an ordinary audience. During the brainwashing conference, my attention at that time was all on the master of Jielu. Looking back, Zhang Shengqian, your behavior is also so suspicious. You sit in the last row, and the people sitting here often psychologically hope to be in control of everything, and here you can make every move in the macro situation, and everyone is listening to the lecture with their legs flat and leaning forward, showing concentration, while you are leaning back with your legs crossed. You know it's a show, you're just watching the show. It's like you just looked at us. “

Zhang Shengqian bowed his head and was silent. I couldn't see his expression, but I felt that he was calm.

Yu Fan continued: "In the end, you were very smart, and you also planted a false accusation for He Wen to give yourself space to escape. But in the end, no matter how you plan, Skynet will be restored and not leaked. If nothing else, the cocoa powder that poisoned the dog is also in this room, because it is not poison, so you don't have to risk being in such a hurry to deal with it. ”

Zhang Sheng sighed, covered his face with a thousand hands, was silent for a while, shook his head helplessly, and said, "Cocoa powder is in my cabinet, I confess, I surrender." With that, he covered his face and lowered his head.

The truth was revealed, and at this moment, a ray of sunlight poured into the room through the window, and the whole room became brighter.

When Chen Xiangyang saw this scene, a relieved smile finally leaked from his face, he looked at Yu Fan, Yu Fan was looking at the sunlight outside the window in a daze, I don't know if it was the reason for the light, Chen Jieyang saw that Yu Fan seemed to be glowing.

Human beings have an innate talent, and when others look at you, no matter which direction you go, you will also have feelings, which comes from a self-protection mechanism in ancient times to prevent being targeted by beasts. Yu Fan felt Chen Frameyang's gaze, turned his head to look at Chen Frame, and the two nodded to each other tacitly, it seemed that the matter was finally over.

Anyway, Chen Jieyang's colleagues did rule out the possibility of He Wen's crime.

Everyone escorted Chen Shengqian and prepared to return to the game.

At the gate, the leaders of the sewage treatment station groveled to see off Yu Fan and his party.

Chen Xiangyang became angry when he saw this stationmaster, and reprimanded: "Your sewage treatment station has mastered the source of life for the people, you TM give me a snack, you didn't find out that ferric chloride leaked overnight?" How do you do regulatory work? What do you think of the common people? I'll come back and clean you up! ”

The stationmaster still greeted him with a smile and apologized again and again: "Yes, yes, I will abide by the teachings of the leader and purify the water for the people." ”

Yu Fan glared at the stationmaster's eyes, and the stationmaster immediately focused his attention on other places.

Yu Fan said sarcastically: "In my opinion, it is not water that needs to be purified, but your sense of responsibility and conscience." ”
