Xiao Ran chuckled and shook his head, saying, "Brother Zhang, I just came here, how could I know everything? I just heard them discuss it before, and with the supplements you mentioned, so I made this judgment."

Zhang Hui grinned, "Yes, we are all human."

Xiao Ran nodded slightly and said, "But now I want to go to the '7.28' case site and then talk to Cheng Yuguo. Can you find someone to take me over?"

"Yes, no problem." Zhang Hui said decisively.

Then he called a young female internal agent named Yu Mengqing, who was of ordinary height and pretty.

"Xiao Yu, this is Xiao Ran and Zhang Lei. They are all from the municipal bureau to help. You can take them to the '7.28' site first, and then go to the detention center to mention Cheng Yuguo."

Yu Mengqing nodded and stared at Xiao Ran for a while before asking Zhang Hui: "Boss, this is what you said before, the fastest man in our city?"

As soon as he finished speaking, Zhang Lei couldn't help laughing, and quickly glanced at Xiao Ran, and immediately put away his smirk.

Xiao Ran turned his head and looked aside with a calm expression. The fastest man in Lin'an City... Can you be exhausted when describing two more words?

"Hello, I'm Xiao Ran."

"Hello, Team Xiao, my name is Yu Mengqing... Wow, your hands are so smooth, your skin is good, it feels better than my little cousin's butt!"

Yu Mengqing held Xiao Ran's hand and looked left and right.

Xiao Ran pulled back his slap that could kill a pig and smiled hard: "The case is urgent, so let's take us to the scene first."

"Okay, you guys go downstairs to wait for me first, and I'll sign two certificates."

Not long after, Yu Mengqing ran down from the building, called Xiao Ran and Zhang Lei to get in the car, and then drove towards Cheng Yuguo's home.

Yu Mengqing's driving skills are very good. On the road where pedestrians at the urban-rural fringe areas do not look at traffic lights, they are still very smooth, not as fierce as Yu Yu was holding the steering wheel.

On the way here, Xiao Ran was also observing the surrounding environment. He had been here in Chengdong District before when handling the Guo Yilei case, but the place he went to was still a distance from this area and he didn't walk from here at that time.

The environment was similar to the previous situation when Zheng Huange was arrested by Guo Yilei case. In the construction area, the relevant infrastructure was not complete and the personnel mobility was high, which often brought chaos.

The car turned into a small road from the main road, turned a few more turns and entered a relatively narrow road. After walking to the center of the road, a two-story self-built building without a yard on the right was the first scene of the '7.28' case.

Due to the rain just one night, there was a turbid puddle on the road in front of Chengyu's country. The stone-paved road was still wet. Xiao Ran looked at the two footprints behind him.

Gravel roads are not like asphalt roads, cement roads, or dirt roads. They are pavements composed of gravels, with many gaps and unfixed structures. Although they are prone to leaving traces, they can easily disappear after being washed by rain.

As recorded in the investigation report, the traffic around Chengyu country is indeed complicated and there is no surveillance equipment. If you want to know more, you can only rely on the power of the masses in addition to the legacy on the scene. Maybe someone saw the murderer that day.

However, after nearly half a month of visit, the Chengdong Branch did not find any witnesses, and the traces at the scene also gained little.

It was almost noon, and many people were preparing lunch. Seeing a police car parked at the gate of Chengyu's country, the idle people around him surrounded him and kept asking whether Chengyu's country killed his wife?

"My little comrade, you have to work harder. There is no truth. We don't dare to go out at night. When it gets dark, we quickly lock the doors and windows. We are not at ease, and we have to find a piece of wood to hold the door from behind."

Several aunts kept muttering to Xiao Ran: "It's so scary. You don't find the murderer. At that time, I heard the sound of Cheng Yuguo's mother. When I went in, I saw... I remember that my body was so painful, it was so miserable, it was really cruel, and the children were scared silly!"

Xiao Ran was pulled by the uncles and aunts. Those people said you and I said mine, which made Xiao Ran dizzy.

After finally seeing the opportunity, he quickly shouted: "Uncles and aunts, don't worry, there will be a result soon. Okay, we have to go in and have a look now. Please support our work, right?"

“Okay OK.”

The surrounding people became quiet, but when Yu Mengqingzhen took the key and opened the door of Chengyu Country, the people at the door immediately left and disappeared.

After all, in the eyes of the masses, people who die in vain are still in such a waste of life, and they are always reluctant to come into contact with them in their hearts.

Putting on the shoe cover, Xiao Ran and Zhang Lei followed Yu Mengqing into Cheng Yuguo's home. Because the curtains were all pulled up, and it was rainy, the room seemed a little dark.

As soon as he entered the door, the first thing Xiao Ran saw was the floor, the TV, the large splattered blood on the wall, and the large dark brown blood on the sofa.

Needless to say, the splashing blood was sprayed out by the deceased after the throat was cut. The large blood on the sofa was penetrated by the corpse when it was on the sofa.

The frictional blood stains next to the large bloodstain on the sofa were left by the murderer when the deceased was invaded when the deceased was in the last life or after the deceased died.

After opening the folder, Xiao Ran seemed to see the murderer's situation when he was fixing the photos taken when the technicians fixed the scene. In addition, the bloodstains were still preserved on the scene.

"Hey, Xiao Ran, look, the masses reported that after the deceased's family quarreled around 10 o'clock, there was no sound."

Zhang Lei turned on the ultraviolet light in his hand and observed the scene while asking: "If a stranger had broken into the house at that time, Li Lu, the deceased, must have shouted, but the people around him did not hear any noise. Could it be that an acquaintance committed the crime, or that was Cheng Yuguo committed the crime? After all, only if a familiar person comes in, will the people relax their vigilance?"

Xiao Ran looked at Yu Mengqing.

Yu Mengqing replied understandably: "We must check these things. We have checked the surrounding people, Li Lu's acquaintances, relatives and friends, Cheng Yuguo's acquaintances, relatives and friends. Although there are those with their physical characteristics, we cannot determine whether they are the suspects."

Xiao Ran said: "Then please tell me the information of those who have been checked after Sister Yu goes back."

"Okay." Yu Mengqing nodded and responded.

Xiao Ran didn't say anything more, and continued to flip through the folders and compare the on-site investigation records at that time to reconstruct the situation after the murderer committed the murder in his mind.

The autopsy report states that the deceased Li Lu had a rupture on the inner side of her lips, which was obviously caused by the murderer's strong cover of her mouth and nose.

Therefore, if the murderer was a stranger, he would limit Li Lu's speech at the first time, and this possibility would be impossible.

Xiao Ran held the folder and walked around the first floor.
