Li Yan looked at Ye Lingtian in surprise and finally asked: "But there are so many people here, where are you going to find that person?"

"To observe the situation and centralized dispatch, you must control the dynamics of this area in real time. He must have a good vision. The best view nearby is the roof of the building opposite," Ye Lingtian pointed to the building opposite and said after saying.

Li Jing looked at the building opposite, then nodded and said, "Indeed, that building is the tallest nearby, and the building in the north and south direction is relatively short. Standing on the roof, you can really see all the surrounding situations. Is there anyone? I will immediately control the roof of the building." After Li Yan said that, she took out her cell phone.

"No, if you set up controls on the roof, I can tell you responsibly that you can't catch anyone. It's still early, and that person will probably appear in half an hour." Ye Lingtian picked up the telescope and looked at it, then lay on the bed and watched TV again.

Li Jing was stunned for a moment, then took the telescope directly from Ye Lingtian's hand and started looking.

"Don't look at him like this. If the other party is on the roof opposite, you can clearly see you holding a telescope and looking at him. That's a fool, then you know what's going on? In addition, pay attention to the angle with the sun. The telescope will have a trace of reflection. If this trace of reflection hits him, if the other party is powerful enough, you will find you." Ye Lingtian reminded Li Yan, then closed his eyes and continued to sleep.

Li Yan frowned and stood in the corner like Ye Lingtian, observing the roof opposite the building.

After waiting for almost forty minutes, Li Yan suddenly saw from the telescope that there was indeed a person on the rooftop of the building, and he was also holding the telescope and secretly watching the surroundings.

"Ye Lingtian, get up quickly, the person is coming." Li Yan shouted at Ye Lingtian nervously.

After hearing Li Yan's words, Ye Lingtian suddenly bounced off the bed, walked to Li Yan, took the telescope from Li Yan's hand and looked at it.

"I'll call someone over right away." Li Yan picked up her phone again.

"What are you going to do? Are you going to kill Li Yuxin?" Ye Lingtian snatched Li Yan's cell phone.

"What is harm? The man is obviously on the roof opposite. I can tell you that I only need a phone call. Unless the other party jumps down from the building, it will be impossible to escape. As long as I catch this person, I can ask him to explain the location of the kidnapper. Return my phone to me. It is rare to have a chance. If he doesn't catch someone, he will leave." Li Yan said hurriedly.

"I tell you, as soon as your person appears, he will run away immediately. In addition, even if you find the other person, can the other person honestly tell you where the kidnapper is? It's impossible. I've told you a long time ago that these people are not ordinary people." Ye Lingtian said that he would not hand over the phone to Li Yan without saying anything.

"Then what do you think you should do? What else can I do besides arresting him?" Li Yan said coldly.

"You take a look and remember the other person's appearance and appearance clearly. Then you ask a few people to come and retrieve all the surveillance videos around here. There are a lot of surveillance in this place. I paid attention to it. There are no blind spots. You should be able to find out where this person came from. I still use yesterday's method and it should be able to find out. If nothing unexpected happens, the place where this person comes out must be the place where the kidnappers hide, so that they can not alarm the snake." Ye Lingtian said lightly.

Li Yan was stunned for a moment. Although she didn't want to admit it, she had to say that Ye Lingtian was indeed the safest way. But she refused to admit defeat and said, "Ye Lingtian, I will believe you again. If the final location of the kidnapper is not found, I will sue you for interference in handling the case."

After Li Yan finished speaking, she snatched the telescope from Ye Lingtian's hand and stared at the other party carefully.

"Okay." After seeing it, Li Yan put away the telescope directly, then took the phone from Ye Lingtian's hand and dialed a number: "Notify everyone to be on standby immediately. In addition, arrange people to switch the pictures of all Skynet surveillance and traffic surveillance near People's Square within an hour. Arrange a few groups of people to take back the surveillance video of all properties here in People's Square, and the speed should be fast."

After Li Yan finished speaking, she hung up the phone directly.

"You stay here and stare, I'll go back and check the video," Li Yan said.

"No need to nail it here. Before three o'clock in the afternoon, this guy will not move. Please remind your people to take secret actions and don't just get out the police car and police uniforms." Ye Lingtian said lightly, then turned around and went out.

Li Yan was very dissatisfied with Ye Lingtian's attitude. You must know that she is the policeman, and she didn't know why she had to listen to him and follow his plan.

When Ye Lingtian and Li Yan returned to the temporary command post, Li Yuxin's house, the house was already crowded with people. At the same time, there were a few more computers. It can be seen that Li Yan's criminal police brigade was still very fast. When the two came back, all the videos of Skynet surveillance and traffic cameras were collected.

After waiting for almost half an hour, several people who went to the People's Square property to pick up the video came back. Li Yan directly retrieved the surveillance video of the building that the two of them saw before and watched it on the computer. After searching for about half an hour, Li Yan finally found the surveillance video of the person entering the building.

"Everyone comes over, look, this is one of the kidnappers. Now you remember the person's appearance, and based on all our relevant surveillance information, we infer where this person came from. Everyone started looking for me. I found it and reported it to me." Li Yan called everyone over and pointed to the man in the surveillance and said.

So, more than a dozen computers began to run at the same time, constantly flipping through.

Li Yan took out a huge city map of Donghai City and spread it on the dining table. Only someone reported the kidnappers' movements, she immediately drew lines on the map with a red pen.

Ye Lingtian kept sitting on the sofa and watching the group of people busy. He waited for almost an hour. At around 1:00 in the afternoon, the last person reported: "Captain Li, the suspect walked out of this intersection, and there was no surveillance in front of him. We found another way to get here, but we did not find any suspect or the vehicle that the suspect was riding in."
