Ye Lingtian also looked around, then said lightly: "Go to the second one", and got into the car after that.

Li Yan was a little angry that Ye Lingtian didn't finish his words, but he didn't dare to say anything, because she had promised Ye Lingtian that she was not allowed to ask why, and she had to listen to everything. She knew that she was just a driver today, so she got in the car and drove to the second crime scene.

The second case was in a high-end community. Li Yan parked his car directly at the property door, got out of the car and found the property manager inside, took the police officer's certificate and took the key from the other party, and then took Ye Lingtian upstairs. The floor where he was located was on the fifteenth floor, with a seal posted at the door. Li Yan tore the seal open and walked in, and said to Ye Lingtian: "This case happened a month ago. The deceased was the general manager of Galaxy Investment. In addition, the deceased's wife and two servants were also killed. This case is very huge. We have always blocked the room, so the traces on the scene here should be kept relatively clear."

Ye Lingtian walked in and took a look. This was a duplex building.

"This is the place where one of the servants died in the kitchen. According to the traces of the scene, the victim was preparing to make breakfast. The incident occurred at around 6 a.m. The other victim died in the hall, at this location, all died of kitchen knives. We cannot judge the order of death between the two. However, based on the weapon found in the hall, we concluded that the victim went to the kitchen. After picking up the kitchen knives and killing the servant who was making breakfast, he saw another servant in the aisle hall and went out to kill the servant, threw the knife directly on the ground, then went upstairs, and killed the couple who were sleeping in the bedroom. The couple who killed the couple was using a gun. The case is clearer, but there are several doubts. First, how did the deceased enter the community. This is a high-end community, and the surveillance is very strict. There are security guards patrolling for 24 hours. We asked the property, but we did not see any strangers at all.

When people appeared, there was no trace of anyone in the surveillance equipment. Of course, what I can be sure now is that the other party must have avoided the surveillance equipment and sneaked in. The second question is, how to enter the door, we checked the door lock, and there was no sign of being pried. This is the fifteenth floor, and it is impossible to climb up. So, we can only conclude that the murderer could only come in from the door, but this door is a very expensive security door. We hired a few very famous local lock-openers. They told us that if this kind of lock has four-story insurance, there is only one possibility that if there is no sign of prying scratching, the other party has a key. So, this question is, how could the other party have a key to the family door? The third question is, why would the murderer kill two servants with a kitchen knife and shoot the couple upstairs?" Li Yan took Ye Lingtian to inspect the scene while analyzing the case for Ye Lingtian.

Ye Lingtian kept silent and took Li Yan around the house, and finally said, "I looked downstairs in this community. It is enough to prevent ordinary people. However, to prevent people who have been trained, it is basically equivalent to not being prepared for any defense. As long as people who have learned some skills, they can enter and exit easily and be undiscovered. There is nothing to say about this. There is a possibility of climbing the window, but the possibility is slim. It is fifteenth floor, duplex building, and without any focus, it is impossible to get up without work. The murderer can only enter through the door. You said that the murderer has a key. I think, judging from this person's way of doing things, it is unlikely that he will be so responsible to steal the key first. He can kill people directly. He opened the door and came in."

"How could he come in without a key?" Li Yan asked.

"You really can't get in?" Ye Lingtian smiled, then walked out and closed the door. Li Yan was stunned for a moment. After waiting for more than a minute, he saw the door open suddenly, and Ye Lingtian walked in.

Li Yan stared at Ye Lingtian with wide eyes and asked in disbelief: "How did you come in?"

"You don't have to worry about how you come in. I just tell you that if you are really a master, it's actually very simple to open this door that you think is impossible to open. As for why you said that you should use a knife first and then a gun, there should be nothing to pay attention to. The main thing is to intercept the killing from close range without wanting to make any sound, so you went to the kitchen and took a knife and cut the servant's neck from behind. Then you found that there was a sound in the living room, so you took the knife and killed it. Of course, his gun must have a muffler, but there will still be a sound. When you arrived at the bedroom, the two of you were sleeping in the bed, and at close range, you could rush over and kill someone, and it might make another person alert and make a sound. Therefore, standing at the door and firing two shots directly is much safer. You know, there is nothing to say. I can't find any clues here.

I guess you must have extracted fingerprints, but nothing is right? The other party must have worn gloves, so it's useless, go outside and take a look." Ye Lingtian said, and walked out and went downstairs. He walked directly to the outside of the community, walked along the periphery of the community, and finally pointed outside and said, "The other three sides are all on the road. There are surveillance cameras on the road. With this person's cautious habit, it is unlikely to go there, so he went out from here. This is a vegetable market. At that time in the morning, the vegetable market should be quite lively, with people coming and going from here. Even if you can see him in the surveillance equipment, you can't suspect it. After all, there are many people entering and leaving the vegetable market in the morning, and it is normal. Let's call out all the surveillance videos of the vegetable market that day and that time period." Ye Lingtian said lightly, and then walked back.

"Vegetable market? Why didn't I expect that this murderer was too cunning. Fortunately, I invited you, a more cunning person, to come. Otherwise, it would be impossible to find any clues. We found all the surveillance monitors in the nearby road section, but we never thought about the vegetable market.

Li Yan followed Ye Lingtian in surprise and said, then started calling to make arrangements.

"Go to the third scene," Ye Lingtian said lightly after getting in the car.

"It's getting late, let's go to have a meal first. I've helped me so much today. I'll treat you to a big meal, thank you." Li Yan said to Ye Lingtian when he saw that the sky was almost dark.

"Let's talk about it first. I have limited time and I can't spend it with you all the time with you," Ye Lingtian shook his head and said.

"You are really confused at all. I kindly invite you to dinner and you are still breathing. If you don't eat, you will be overwhelmed. I tell you that if you are too late, you can only go back to the task force to eat instant noodles and lunch boxes." Li Yan said to Ye Lingtian angrily, and then drove to the third case site.
