The execution of the police is quite strong, and it is very quick to confirm the target, assign the task, and set off for action. It took Lian Yu half an hour to find the IP address of the user with the ID of Erha, No. 64 Shell Street, and the police took the fastest time to start monitoring him, with the aim of catching the murderer before he committed the murder.

At this time, on Shell Street, on the side of the road in Building 64, a van that is not obtrusive is parked aside, if you don't look closer, you don't think you will find that there are actually four people sitting inside, and the eyes of all four people are looking in the same direction - the entrance and exit of Building 64.

"Although it's so late tonight, there shouldn't be anything to discover, but you still have to keep an eye on me, don't slack off, don't hear it." The one sitting in the back seat thought the older one was facing the other three.

"Got it, Team Xu." The three replied a little casually.

"Spirit, now the four of them take turns staring, I'll take a sample first, you guys take a rest first, next, Xiao Liu'er will pick me up, then Lao Ma, and finally, Ah Qin, don't be lazy." Team Xu gave the order again, and the others nodded and answered. Although the three of them are a little casual, they still listen to Team Xu's words very much, and after following Team Xu for so long, the three of them take care of him in mind, so Team Xu's orders are absolutely obeyed and completed.

"This time this murderer is really a bit difficult to deal with, this is the most difficult case I have encountered since I became a criminal policeman, more than half a month has passed, the only information I have is that a person who doesn't know when the murderer is going to kill him, we can only wait for the rabbit, this is the most uncomfortable." The old horse curled up in a comfortable position to sleep in.

"Yes, this murderer is like a ghost, every time he kills someone, he doesn't leave a trace, he kills four people, every time I go to the scene, not even a single phlegm or hair is missing." Xiao Liu'er also continued with Lao Ma's words.

"Take a good look, when you catch this murderer, you don't all know if he is a ghost or a god." Team Xu's eyes did not leave the target he was staring at as he spoke, and his work began from the moment he issued the order.

Lao Ma, Xiao Liu'er, Ah Qin also agreed with what Team Xu said after hearing it, whether it is a human being a ghost or a god, as long as he appears, catch him, and everything will be clear at that time.

"Let's take a break, we're busy tonight, don't waste your energy on this." Team Xu looked at the three people who were still discussing and urged them.

Several people adjusted their postures, squinted their eyes, and after not playing for ten minutes, there was a snoring sound, hearing this sound, Team Xu smiled lightly, and looked at Building 64 more seriously. Although it was early in the morning and there was no figure on the street at all, Team Xu did not have any ambiguity.

After half an hour, Xiao Liu'er, who was sitting in the co-pilot, suddenly turned his head and looked at Team Xu without saying anything.

"What? Can't sleep? Team Xu asked him.

"Sort of, rarely sleep on this occasion, I really can't sleep." Xiao Liu'er smiled a little embarrassed.

"It's okay, it's normal, if you can't sleep, just play with your phone, you guys are young and energetic." Team Xu looked at this young man who had just joined the criminal police team for less than two years, he had always taken him with him since he came out of the police academy for internship, and he was a bit like his own child to this child.

"It's boring to play with your phone, or don't you team up, you can tell me about the cases you have handled before, I liked to listen to case studies when I was in school before." Xiao Liu'er looked at Team Xu with some expectation.

"Hehehe, okay, let's talk to you." Team Xu did not refuse.

An old and a young policeman chatted in the car about the cases that had occurred in recent years, and just as they were talking about the excitement, there was a sound of footsteps on the quiet Shell Street, and a dark figure carrying a bag was walking down the street, slowly approaching Building 64.

When the black shadow arrived at Building 64, he glanced around a few times, and one turned around and went inside.

"Somebody's in the building." Team Xu, who was talking about the case, suddenly found that there was a black shadow in his sight entering Building 64, he immediately reacted, skillfully opened the car door and followed, Xiao Liu'er also followed closely behind Team Xu.

"Could this be a murderer?" Xiao Liu'er nervously followed behind and said, this is a serial perverted murderer who killed four people in a row, Xiao Liu'er tried very hard to calm himself, but he was still nervous, and sweat flowed down his forehead.

"Follow first, and see how we look at it." Team Xu said calmly, which also made the nervous Xiao Liu'er not as nervous as he was just now. After all, Team Xu is an old criminal policeman, and he has served as the captain of the action team many times, and he has already calculated a lot in his heart while keeping up, if this person is a murderer, he will definitely go to the fourth floor, because the user with the ID of Erha lives on the fourth floor. Team Xu touched the gun on his waist and thought about how to subdue him.

All this, Ji Kun and the others who walked back naturally didn't know, now they are still worried about tonight's accommodation, originally Lin Shu's idea was to find a hotel to stay in for a few days, but I didn't expect the hotel in this city to be so expensive, as far as Ji Kun, two people from poor counties, where did they get the money to live in this kind of place, if they asked Peng Yingsi to borrow money, he really couldn't open it.

"Go to my house." Peng Yingsi sighed, how could a wise woman like her not see the so-called self-esteem of these men, and now that there has been an obvious breakthrough in this case, it is estimated that the two of them will not live for long, so it doesn't matter. Even Peng Yingsi didn't expect the success of this case, Lu Wushuang was also messed up before, and now it was suddenly solved, although Ji Kun felt that there were still doubts, but there was nothing more reasonable than Lu Wushuang's reasoning, and when the time came, he would know what was going on when he caught the murderer, thinking of this, Peng Yingsi was also relieved, and soon the nightmare should be over.
