Replace the evil way

Cheng Aiyue carried the evidence box, Xiangyang followed behind, and together with Cheng Zesheng arrived at this mansion hidden deep in the remote mountain again.

They put on the three-piece suit that is necessary for entering the arena. Cheng Aiyue asked curiously: "Deputy Captain Cheng, why did you suddenly remember looking for fire/powder residue?"

Xiang Yang was also staring at him curiously, and Cheng Zesheng coughed lightly: "A friend I consulted with was his guess."

"Oh, handsome Cheng Da is also looking for foreign aid? It's so strange, so strange." Cheng Aiyue frowned and smiled, "Do you know that the nickname our bureau gave you in private is one of the four famous arresters?" 'ruthless'."

"why?"

"Because you don't accept any favors, and you never ask for help. You are really heartless."

"..." Cheng Zesheng didn't want to talk nonsense, and pointed to the sofa, "The point is that, the gaps and inner linings have been checked carefully."

When the work started, Xiangyang stood aside holding a small screen, and Cheng Aiyue held a portable microscope, swimming on the surface of the sofa.

"It's all dust, bacteria, silky cotton, stains... Tsk, this sofa is so dirty that I get goosebumps all over my body." Cheng Aiyue smiled at Xiangyang, "Kid, do you want to increase the magnification for you to see?" See how dust mites work?"

Xiang Yang's scalp was numb, so he quickly refused.He thought of those invisible bugs, the sweat pores stood on end, and if you don't know about some things, you won't care so much.

"Eh? There are gray and black particles here, handsome guy, do me a favor and lift up the lining."

Cheng Zesheng lifted up a square sofa cushion, Cheng Aiyue knelt on the sofa, and the lens of the microscope scanned the gap.The gray-black particles are not conspicuous in the dust, but under a high-power microscope, they still show a solid state that is completely different from dust.

"The distribution area is mainly concentrated on the surface of the sofa, and there are a few residual particles falling into the gaps of the sofa. The color and shape look like unburned gunpowder particles, and the specific components still need to be extracted back to the laboratory for analysis."

Cheng Meiyue, a professional trace inspector, looks alike, so at least 80% of them can be sure that it is shooting residue.Xiang Yang was amazed: "There really is! Deputy Cheng, who is that friend of yours? Why is he so powerful?"

"Yeah, I'm also curious." Cheng Aiyue took out the electrostatic adsorber and extracted the residue, "How did he figure it out? There is no sign of firearms at this scene. Who would have thought of this layer? "

"..." Cheng Zesheng didn't answer, he couldn't tell them that a shooting happened in the world next door, right?We can only ask them to fix it quickly and bring it back to the laboratory to analyze the ingredients as soon as possible.

Now there is only the possibility of the merging of two parallel worlds, everything has to wait for the genealogy of the ingredients, and then compare it with He Wei's report to determine whether it is the same ingredient before drawing a conclusion.

"By the way, have He Wei's clothes been tested for gunshot residue?"

Cheng Aiyue shook her head: "No, his shirt is very clean. If we found gunpowder particles, we would have told you."

In He Wei's autopsy report, there was no indication of residual gunpowder components, gun oil, or metal debris on his hands.Cheng Zesheng believed that Jiang Tan would not miss it, and the second autopsy was so meticulous that it could even find out He Wei's ankle injury when he was a child, let alone such obvious traces.

If the scenes in the two worlds are really related, what role did the dead He Wei play in the shooting?

After the shooting residues on the sofa were extracted, Cheng Zesheng and others carefully inspected the corners and corners of the living room, and finally found very few gunpowder particles and metal debris, a few sporadic particles, but according to the connection Extending down, it is just in the direction of one of the overlapping shoe prints in the living room.

Apart from these remnants, there is no trace of the shooting in the mansion.Including the courtyard outside the mansion and the back mountain, police dogs have visited twice. Their sense of smell is much more developed than that of humans, and they still haven't found any clues.

"Can the composition analysis come out tonight?" Cheng Zesheng asked.

"Brother, look at what time it is, as I said last time, it's not so fast to make coffee." Cheng Aiyue took off her gloves and complained, "Why don't I give you the lab and see how long you take it." Can be tossed out."

"Oh." Cheng Zesheng threw the plastic gloves into the recycling bag, "Then work overtime tonight, hard work."

Cheng Aiyue's expression changed, and she turned a corner when she reached the mouth of Zaan's quotations, and hummed: "Understood, don't worry, as long as the report comes out, I will report it even in the early morning!"

Cheng Zesheng doesn't care, he goes to bed late now, what is the early morning?I was still discussing the case with that "friend" in the early morning.

He Wei and Chongzhen stood at the crossroads, facing the shopping mall, with a huge LCD screen hanging, and the advertisements played in turn.

They waited for 5 minutes for the endorsement of Cheng Zesheng's famous watch. After seeing it, Chong Zhen agreed with He Wei's speculation even more.At that time, Cheng Zhenqing was going to leave directly, but it happened to be Cheng Zesheng's commercial, so he stopped for a few seconds and waited for the commercial to end before leaving.

He Wei raised his head and stared at the screen, and said calmly, "Although the two brothers didn't grow up in childhood, they have a good relationship."

"Yeah, during the period of hiding in Tibet, except for the necessities of life, I basically didn't go out without going out, and I was able to stay on the street for so long just to watch an advertisement of my brother."

He Wei smiled: "You are the only child, so you can't understand it."

Chongzhen's teeth are sore, isn't it because he has a younger brother?It's like showing off if you have something to say.

It's no wonder that He Wei is extremely indifferent to the relationship between men and women, and has only a handful of friends, only family affection is the most important thing.His parents divorced since he was a child, and he followed his mother and younger brother with his father. Although they grew up in different environments, the relationship between the two brothers not only did not fade, but cherished each other more because of the distance.

They followed the route Cheng Zhenqing walked to the narrow alley.There are two grocery stores at both ends of the alley, and the shopkeepers are all white-haired old men who read newspapers with presbyopic glasses. They don't pay attention to who passes by, and only look up when they come to do business.

He Wei observed this small, sparsely populated intersection. Cheng Zhenqing chose the correct route. There are no traffic lights on this street, and there are no monitoring on the two roads. It takes 100 meters to get to the main road ahead before it will be lively.Moreover, there were two small doors that seemed to be opened by residents privately leading to the two communities, and Cheng Zhenqing's whereabouts became more complicated.He might have gone out from three intersections; he might have entered the community and then left through another door; or he might have simply lived here and gone home.

"After I visited last time, I felt that this Cheng Zhenqing was a chicken thief." Chong Zhen looked around, "Look, how many crossroads can be found so bright? There is not a single eye, I am also convinced."

"Then you have to report the situation to the traffic control department and the urban management department. The control is not in place, so criminals can take advantage of it." He Wei casually chatted, pointing to both sides of the street, "Where do you think he went?"

"Guess where to go, this way." Chong Zhen casually pointed to the left.

"I think it's this way." He Wei walked to the right, and Chong Zhen followed: "What do you say?"

He Wei smiled and said nothing, not in a hurry to answer.When he reached the next crossroads, Chong Zhen looked up and saw that there was a gym on the opposite floor, which was the one that He Wei made people focus on, and he slapped his forehead: "Damn! Why didn't I remember? The map is still mine. For you!"

"That's why you have to wait a week for a case that I can solve in three days." He Wei smiled lightly, "And last time at Cheng Zesheng's house, didn't you ask me why I knew there was something wrong with the book?"

"why?"

"Because the thickness of that "Guiguzi" is not right. I also have a copy at home."

"..."

Chong Zhen sighed and shook his head, forget it, isn't it normal to lose to He Wei?Ever since this man entered the city bureau, he had no unsolved cases in his hands. Conan had to kneel before him. After all, he had never seen Conan's autopsy, and He Wei's autopsy was a good one.

There were two colleagues in the car staring at this gym, and Chongzhen asked them to drive a little farther, or get down and sit in the opposite cafe.How did it work?Didn't you see this street, did they have a car here?I'm afraid that I don't know that someone is following me.

He Wei went upstairs to the gym, and after showing his ID, he took Cheng Zhenqing's photo and asked the front desk: "Have you seen him?"

The front desk stared at the photo for a long time, and smiled apologetically: "It seems not."

"He is more than 1.8 meters tall and has a thin body. He usually wears sunglasses and a mask. Have you ever had such a customer in your gym?"

"Oh, it seems that there is such a person, but he is not a guest, he is here to find our private teacher Ding." The receptionist picked up the walkie-talkie, "Xiaomeng, please ask private teacher Ding to come to the front desk, someone is looking for you."

Five minutes later, a sturdy, crew-cut man in shorts and a racerback came out. He Wei raised the ID in his hand: "Excuse me, I'll ask you a few questions, it will be over soon."

---

After Chong Zhen finished smoking a cigarette downstairs, He Wei came down and patted him on the shoulder: "Have you brought the map?"

"Enough of the question so soon?" Chongzhen took out the map from his arms, He Wei took out a pen and added a few points on the map, Chongzhen looked down: "What is this?"

"The false identity he used was 'Ma Guangming'. He had known a private trainer here for about half a year. The private trainer mentioned that they had drunk together a few times and punched him a few times, but he hadn't seen him this month. The number Shut down, and WeChat can’t be contacted.” He Wei drew these points as extension lines, and finally produced a meeting point: Hutaoli Community.

Chongzhen has already taken out his mobile phone, called Hu Songkai, and asked him and Yun Xiaoxiao to go directly to investigate the Hutaoli community and investigate a person named "Ma Guangming".

After hanging up the phone, Chongzhen sighed: "It's still useful if you come here, the scope of investigation has been narrowed down to a single community."

He Wei put away the map and told him not to be too happy.It has been a while since the incident, and it is not clear whether Cheng Zhenqing took advantage of this time to move. Cheng Ze's death in the arsenal will definitely be exposed, and he may escape abroad if he has the foresight.

Chongzhen stroked his chin, pondered for a few seconds, and said firmly: "No. He will definitely not leave here."

"The two brothers have a good relationship. Cheng Ze will not just walk away after he is dead."
