The sky was gray, it was the darkness before dawn, Haizi suddenly woke up, opened his eyes and saw that Yang Zi was still staring at the gate of the community intently, and couldn't help but feel a little embarrassed. He didn't make a sound, stared at Yang Zi's silhouette for a while, and his thoughts drifted to the day when he was assigned to the criminal investigation team. At that time, he was only 212 years old, and his dream had always been to be a lively traffic policeman, but he was sent to become a criminal policeman. In the first two days of work, I was dissatisfied with my stomach and a little resistant to work, but it was Team Yang who patiently taught myself some work skills and professional knowledge that the criminal police should know. I still remember that within two weeks of joining the work, I encountered an arson case, and a corpse was found in the fire, which was charred and blackened. At that time, when I saw the scene, I thought it was just an accidental fire, but I didn't expect Team Yang to come over and open the mouth of the deceased and take a look, saying that this was an intentional homicide case, and the purpose of arson was to destroy the corpse. At that time, I thought that the captain was playing tricks, but later Dr. Lin came and said that it was a murder case. After secretly inquiring with Dr. Lin, I learned that if a living person was burned to death in the fire, more than 80% of them were suffocated by smoke, and soot and charcoal deposits could be seen in the mouth and trachea of the deceased, but the corpse's mouth was clean and there was nothing, so it can be concluded that it was deliberately set on fire after death to achieve the purpose of disturbing the vision. Later, the captain also said that not only could he tell whether the corpse was killed or burned, but also the direction in which the corpse was on the ground. He also explained to himself that when a living person is burned to death in the fire, his head is facing the place where the fire is least and his feet are facing the place where the fire is the largest. From that moment on, I realized that the work of the criminal police was far more difficult and meaningful than I imagined, and the reverence for Team Yang was also deeply rooted in my heart at that moment.

"Awake?" Haizi was thinking wildly, when he suddenly heard Yang Zi talking, and hurriedly came back to his senses and agreed: "Hmm." Team Yang, did you find anything? ”

"I didn't see anything out of the ordinary. Let's go get something to eat, go back to the team, and then go to Ni Xiaotian. Yang Zi moved his muscles a little and started the car. Less than eight o'clock, the two of them came to the office building of Xinya Group again, Haizi remembered that Yang Zi didn't call him to get up to change shifts last night, and he was a little reluctant to go, so he whispered to Yang Zi to squint for a while, and then call him. Yang Zi thought about it and agreed.

The sun rose and shone on the earth, adding a layer of golden light to the surrounding scenery, and the originally silent New Asia Group began to be lively with the bustling flow of people coming to work. At 8:45, a black BMW stopped in front of the office building, and Ni Xiaotian got out of it. Today's Ni Xiaotian looks energetic, wearing a well-tailored suit, looking radiant and graceful. Watching his back disappear into the building, Hai Zi was stunned, is this Ni Xiaotian? How is it that yesterday and today have completely changed? Yang Zi was awakened by the sound outside, and also saw this scene, he didn't have any expression on his face, just said a short "go", and took the lead towards the office building of New Asia Group.

Ni Xiaotian opened the door and saw Yang Zi and Hai Zi appear in front of him again, he didn't seem surprised, but he was calm and calm, and said for a long time: "Please come in, two police officers, please come in." Has there been any progress? ”

Yang Zi said frankly: "Mr. Ni, it seems that you are mentally prepared for our visit again. I don't go around in circles, I came to ask you for the key to Li Yan's residence, go in and search to see if there are any valuable clues. ”

"Huh." Ni Xiaotian laughed. "I've thought of it, so the keys are ready." After speaking, he took out a bunch of keys from his pocket and spread them in the palm of his hand and handed them to Yang Zi. "Do you want to come in and continue talking?" After watching Yang Zi take the key, Ni Xiaotian asked easily.

"It's fine. I just have a little bit of a situation that I want to know more about. Yang Zi also replied with a relaxed smile.

The conversation revolves around what happens after their argument. Ni Xiaotian himself narrated that after he was very angry at that time, he felt that he could no longer stay under the same roof with such a woman with a bad heart, so he took his bag, opened the door and rushed out. When he went downstairs, he didn't pay attention, and almost bumped into a person, and in his anger, he didn't think much about it, glared at the man and left. Ni Xiaotian said again that since then, he has never been to Li Yan's place, nor has he taken the initiative to contact her. Later, Li Yan called his mobile phone twice, and when he saw that it was Li Yan's phone, he directly pressed it and didn't answer. Once I called home, it was Ni Xiaomei who picked it up, as if Li Yan told Xiaomei that she was going back to her hometown to get married, and he knew that he must be playing tricks again, so he didn't ask at all as if he didn't know. Li Yan saw that he resolutely refused to turn back, and slowly stopped harassing him. After saying this, he was a little embarrassed but seemed very sincere and said to Yang Zi: "It wasn't until yesterday that you came to me and talked to you that I seemed to have come out of my confusion. For more than two months, I had been suffering from self-blame and guilt. Every day when I go back and see my wife and daughter, and see how much they care for me as always, I feel like a sinner with a heavy moral baggage. Now, I'm finally getting easier. ”

Yang Zi was noncommittal about what he said, and was silent for a while, and was about to say something, when Ni Xiaotian's secretary knocked on the door and came in and said that the guest he had made an appointment had come. "Then let's do it, Mr. Ni, you are busy first, let's go over there first." Yang Zi took the opportunity to say so.

For the second time, they came to the community where Li Yan lived before her death. On the way, Yang Zi called Crow and asked him and Xiaopang to go to Li Yan's parents' house in Dawan Village, Luping Town, Luping County, G Province as friends to investigate and find out what happened to her before she died.

The door was opened, and there was a faint musty smell from the long-term uninhabited inside, and after fanning their hands in front of their noses, they stepped into the door. It can be seen that the master was in a hurry when he left, there was a homely dress thrown on the sofa, a few shoes were thrown on the ground, and some food on the table had long been covered with long green hair. The furniture was covered in dust, the doors and drawers were closed, and there was no sign of a fight. After putting on their gloves, Yang Zi and Hai Zi began to search the room. At this time, the mobile phone thrown on the sofa attracted Yang Zi's attention, he carefully picked it up to check, this is a Nokia straight board machine, Yang Zi pressed the switch and found that there was no power. Looking around, he saw that the charger was next to the TV not far away, and he turned on his phone after walking over and plugging it in. In the call log, there is an incoming call, showing that the call time is more than two months ago at 21:30 on the evening of May 14, and the call time is 1 minute and 49 seconds. Yang Zi took out his mobile phone and dialed it.
