Chapter 19
After Yu Fan finished speaking, the air froze for a few seconds.Everyone, you look at me, and I look at you.

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

Zhang Shengqian's expression slowly darkened.

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

Chen Xingyang 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 retreating was far inferior to Zhang Shengqian's rushing speed.

Sooner or later, Chen Xingyang flew up from outside the door and kicked Zhang Shengqian, who was rushing towards Yu Fan, to the ground.If it was a few tenths of a second later, the consequences would be disastrous.

Chen Xingyang's colleagues also rushed back to the room, subduing Zhang Shengqian in two hits.Zhang Shengqian did not make any struggle.

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

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

Yu Fan broke into a cold sweat from the fright 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 again, so he teased Chen Xingyang: "Old Chen, why is there a fighting link here? Isn't that how the script was written?"

Then he immediately turned serious and said to Zhang Shengqian: "Zhang Shengqian, you don't have to quibble, you are the one who played tricks in Beiqiaogou Village, and you were the one who sabotaged the monitoring and leaked ferric chloride, right?"

Zhang Shengqian continued to pretend to be confused: "I don't know what you are 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 Zhang Shengqian's shoe from under Zhang Shengqian's bed, lifted it up to show everyone, and saw faint traces of blue in the gaps in the sole.

Yu Fan said quietly: "Locar's law of matter exchange, where there is a transfer of matter after contact between objects, the target object will take some matter from the source object, and at the same time leave some of its own matter in the source object. On the source object. When we first went to the small courtyard of your stronghold in Beiqiaogou, you had cleaned it up very clean in advance, and there were indeed no clues left. But you should never provoke our people's police , Maybe you think we found this stronghold too fast. After we left, your anxiety and worry made you return to this small courtyard again, creating a weird illusion of blood sacrifice to the entire village, trying to create public opinion to scare away and Drive us away. But because of your anxiety, your plan had a flaw. In fact, before we left last time, I sprinkled a little anhydrous copper sulfate powder on the ground in that house. In the dry winter, they Mixed with the ashes on the ground, it is not easy to be noticed. But this time you returned to the scene and unknowingly took them away! This shoe of yours should be the shoe you wore to the scene the next day, right?"

Yu Fan paused, poured a bottle of water on the table onto the soles of the shoes, and the blue color became more conspicuous.

Chen Xingyang secretly complained: "When you go out, you actually bring anhydrous copper sulfate with you. Old Yu, you really have it. What are you chemistry people thinking all day long?"

Yu Fan continued: "Anhydrous copper sulfate is gray or white solid, and after absorbing water, it turns into blue copper sulfate pentahydrate. How do you explain now, where does the anhydrous copper sulfate on your shoe soles come from? The sewage treatment plant should Can't you use anhydrous copper sulfate?"

Zhang Shengqian bowed his head and thought frantically, trying to find a countermeasure for sophistry.

Yu Fan stared straight at Zhang Shengqian, and said slowly: "Actually, we have met, right?"

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

Chen Xingyang was worried that this guy was still playing tricks, so he moved two steps closer to Yu Fan to protect Yu Fan.Suddenly, Chen Xingyang himself remembered something: "Yes, yes, I mean it looks familiar. A few days ago we destroyed the MLM organization of Master Jielu. You seem to be an audience in it?"

Yu Fan: "Looking at it now, he is not as simple as an ordinary audience. During the brainwashing conference, my attention was all on that Master Jielu. Looking back, Zhang Shengqian, your behavior is also so suspicious. You sit In the last row, people who sit here often hope to be able to control everything psychologically. Here, every move can be made macroscopically. Everyone’s listening posture is to put their legs flat, lean forward, and show concentration, while you are Cross your legs and lean your body backward. You know it’s a performance, and you’re just watching it. Just like you were watching us just now." (This is also the inspiration Yu Fan got from the performance of the Qigong master in Chapter 15, the real People behind the scenes will sit at the end and watch everything quietly)
Zhang Shengqian bowed his head and remained silent.Although I couldn't see his expression, I felt that he was very calm.

Yu Fan continued: "In the end, you were very smart, and you didn't forget to set up an insurance policy. Once the police raided, you could plant the blame on He Wen and buy yourself room to escape. But in the end, no matter how you plan, Skynet will always be there. If there is an accident, the cocoa powder that you poisoned the dog to death should also be in this room, because it is not poison, so you don't have to take the risk to deal with it in such a hurry."

Zhang Sheng sighed, covered his face with his hands, was silent for a while, shook his head helplessly, and said: "The cocoa powder is in my cabinet, I confess, I surrender." After finishing speaking, he lowered his head again covering his face.

The truth came to light, and at this moment, a ray of sunlight poured into the room through the window, making the whole room even brighter.

Seeing this scene, Chen Xingyang finally showed a gratified smile on his face. He looked at Yu Fan, who was staring at the sunlight outside the window in a daze. I don't know if it was because of the light. Chen Xingyang saw that Yu Fan seemed to be hair Light.

Humans have an innate talent. When others are looking at you, no matter which direction you will feel, this comes from a self-protection mechanism in ancient times to prevent being targeted by ferocious beasts.Feeling Chen Xingyang's gaze, Yu Fan turned his head to look at Chen Xingyang, and the two nodded to each other tacitly. It seemed that the matter was finally over.

After all, Chen Xingyang's colleagues did rule out the possibility of He Wen committing the crime.

Everyone escorted Chen Shengqian, ready to return to the game.

At the gate, the leader of the sewage treatment station humbly sent off Yu Fan and his party.

Chen Xingyang became angry when he saw this station manager, and reprimanded him: "Your sewage treatment station controls the source of life for the common people, you fucking serve me some snacks, and you didn't find out that the ferric chloride leaked all night? How do you supervise it?" Workers? What do you think of ordinary people? I'll deal with you later!"

The station master still greeted him with a smile, and apologized again and again: "Yes, yes, from now on, I will definitely abide by the teachings of the leaders and purify the water for the common people."

Yu Fan glared at the stationmaster's eyes, and the stationmaster immediately turned his gaze to other places, feeling guilty.

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

　The biggest difference between man and beast lies in wisdom and conscience—anhydrous copper sulfate
