"The culprit behind the scenes?" Ren Xiaosu looked at the Northwest intelligence officer who came to report the news: "How do you determine that it is the culprit."

The intelligence officer from the northwest explained: "Wang Yun said that this person appeared at the intersection where Mr. Jiang Xu had an accident. Two hours later, he appeared in the place where Mr. Jiang Xu was almost hit by a billboard. This is a typical behavior of returning to the crime scene to observe secretly, and he was very cautious. Generally, combatants would never do this. Only the person who was hiding behind the scenes to plan everything will return there."

Ren Xiaosu walked out of the villa. He was not very interested in the targets he had already captured. If the person who was caught by Wang Yun was the culprit behind the use of the heartworm, then finding this person will all be solved together.

At this time, Ren Xiaosu turned to look at Luo Lan, Zhou Qi: "I bring this person back. Can you pry open his mouth?"

But Zhou Qi smiled sinisterly and said, "After my torture, there is no one who doesn't open his mouth. Don't worry, the water system ability is just right for torture."

Ren Xiaosu left the villa and said to the Northwest intelligence officer: "Print the photo of that person and send it to everyone, and ask if anyone knows his identity."

As a result, it took only ten minutes to send back the news: Luo Zongren, 29 years old, a technical worker in the water plant, came to work in Luocheng more than two years ago and was hired by the water plant at a high salary.

However, after asking all the residents in the villa area, no one knew the address of Luo Zongren.

Northwest intelligence personnel brought a resident: "Young Marshal, he knows this Luo Zongren."

The resident said, "Hello, I am a grassroots worker in the water plant. I am very familiar with Luo Zongren. He solved many technical problems. He stayed in our branch for a while. But no one knew where he lived. When we went to dinner after get off work, he never participated. He only knew that he liked reading and stayed in the office to read books and never went anywhere."

"What are his usual habits?" Ren Xiaosu asked.

"There is nothing else except reading," the resident replied, "There is one thing. Luo Zongren likes to wash his hands very much. Every time he works, he has to wash his hands when he touches the equipment. He is dressed neatly. Many little girls in the factory think he is different from our sloppy grassroots workers, so there are still girls who have pursued him."

"Is there a cleanliness obsession?" Ren Xiaosu asked in confusion. For some reason, he instantly outlined an extremely self-disciplined and hidden image in his heart.

But what should I do if I don’t know the other party’s address? Ren Xiaosu told the intelligence staff: “Contact the water plant, the staff list in the factory has the addresses of all workers. Although it may be fake, it is also a clue.”

As a result, when Ren Xiaosu was still unable to know the other party's address, a call came from the northwest: "Wang Yun has tracked the other party's behavior through surveillance video and determined the other party's address range. It is near No. 149, Kaixuan Road! Take his photos and ask the nearby residents, and you will definitely ask, there are only two residential buildings."

Ren Xiaosu immediately led the team to rush out and headed straight to No. 149, Kaixuan Road.

After arriving there, Ren Xiaosu found the owner of the grocery store next to the road and took out Luo Zongren's photo: "Hello, have you ever seen this person?"

The grocery store owner recognized Luo Zongren at a glance: "He, he is passing by me every day in the water plant uniform. Of course, I remember that he seems to live nearby, and he bought firewood, rice, oil and salt from me."

"Then do you know where he lives?" Ren Xiaosu asked.

"Just up the residential building in front, I don't know what's specific," the boss replied.

After saying that, dozens of intelligence personnel from the northwest quickly surrounded the residential building with guns, and even Yang Xiaojin was looking for the best sniper position a few hundred meters away.

Yang Xiaojin said in the headset: "It's ready."

Ren Xiaosu then walked towards the residential building. An old man and a lady were playing mahjong downstairs, and he took out the photo and asked, "Do you guys know which floor he lives on?"

An old lady looked at the photo and smiled, "Isn't this Xiao Luo? He lives on 401 on the fourth floor. Are you worried about him?"

"It's okay," Ren Xiaosu smiled. He waved his hand and asked the intelligence personnel to take the people away so as not to hurt them by accident when the battle came to an end.

The residential building is very dilapidated, with only four floors in total. Ren Xiaosu and several intelligence personnel all the way upstairs.

As a result, when we reached the fourth floor, the door of 401 was just a false cover and was not closed.

Ren Xiaosu had an ominous premonition in his heart. After he pushed open the door, he saw that the furnishings in the house were very simple, with only some of the most basic tables, bookcases, kitchen utensils, and a bed.

Ren Xiaosu remembered a sentence: When a person’s heart is extremely complicated, he will have extremely high requirements for his living environment and must be concise and neat.

There was no one in the room, and the other party seemed to have noticed the danger in advance, so he left early.

On the table opposite the door was a playing card, a spade.

The card was placed in an upright manner, as if it was Luo Zongren's silent mockery of Ren Xiaosu and the others.

The other party guessed that Ren Xiaosu and the others would definitely find this place, not only left early, but also left a mark as if they declared war.

This is a high IQ criminal. The other party not only enjoys the implementation of the plan, but also enjoys the sense of accomplishment of teasing and controlling others.

Ren Xiaosu turned around and went out: "I informed Northwest that the other party had already escaped, but he could not escape this barrier. See if there is any other way to find this person."

At this moment, Ren Xiaosu's face was calm.

After the news came back to the northwest, Wang Yun stood in front of the hundreds of screens in a daze. He suddenly said, "This kind of person will definitely leave a way out for himself, right? Everyone says that cunning rabbits have three holes. Such cunning high-IQ criminals will definitely leave a way out for himself. Come on, call out all the videos about him on the way to and from get off work. I want to see all his trajectories in the past month."

The project is extremely large, and the other party’s journey to and from get off work is eight or nine kilometers. It takes dozens of videos to piece together the other party’s trajectory.

There are hundreds of surveillance monitors in the entire barrier, and they have to first pick out the videos on that road from these hundreds of videos.

Just when the soldiers were in a dilemma, Wang Yun said: "I marked all the videos before, and the surveillance videos on his work path were 102, 129, 130, 141..."
