After Xu Lang returned to the bedroom, he lay on the bed, looked at the photo album of his mobile phone, and looked at the video he had just recorded.

The video was pitch black, I couldn't see anything clearly, and when the camera lens moved to the roof of the residential building opposite, a red dot suddenly appeared, the red dot existed for a very short time, but it did appear, which made Xu Lang, who saw this, feel a layer of haze in his heart.

He remembered the 810 case, what Song Anguo said to Xu Lang before jumping off the building and committing suicide.

"He's back, he's in S City."

At the beginning, when Xu Lang heard this sentence again, he faintly felt that Song Anguo was the murderer of his family in his mouth, but whether the truth was like this or not, Xu Lang had no way of knowing, because Song Anguo was dead.

After Song Anguo's death, Xu Lang thought of this sentence more than once, and repeatedly thought about who Song Anguo said, but there was no result, later, Xu Lang went to the countryside to recuperate, and after returning from the countryside, he did not encounter any accidents, but tonight, by chance, Xu Lang found that someone seemed to be monitoring him, so who is this person? Is it the one Song Anguo said before he died?

With this doubt and uneasiness, Xu Lang gradually fell asleep.

One night without a dream, the next day.

When Xu Lang woke up again, it was already nine o'clock in the morning, because the homicide was discovered last night, and Xu Lang was both the informant and the first to go to the scene, so Xu Lang went straight to the public security bureau after washing up.

When Xu Lang came to the second criminal investigation team, everyone was holding a case analysis meeting, and everyone was not surprised by Xu Lang's arrival, and after Xu Lang sat down, everyone continued to analyze the case.

The murder scene is very simple, clear at a glance, and can be said to be very clean.

First of all, according to Li Lei's investigation of the scene, in addition to the fingerprint footprints of the deceased Tian Yang, as well as the footprints of Xu Lang and the police handling the case, no fingerprints and footprints of other suspicious persons were found at the scene.

Secondly, according to the autopsy of the deceased Tian Yang's body by forensic doctor Ye Xuefei, the deceased was a sharp weapon that pierced the heart, resulting in excessive blood loss and shock to death, except for a wound left by the kitchen knife, no other wounds were found on the deceased's body, and the tool of the crime was a kitchen knife in the kitchen of the deceased's home, and no fingerprints of the second person were found on the kitchen knife except for the deceased's own fingerprints.

Then, Lu Xing retrieved the surveillance video of the community and found that the deceased Tian Yang returned home at seven o'clock in the afternoon the day before yesterday, and then he never left the community, and during this period, no suspicious persons were found to have entered the community.

Finally, according to Zhao Hua's visit to the residents of the community, the residents of the community reported that they usually met Tian Yang when they were commuting to and from work, although they were not familiar with each other, but they all knew each other, and they were a little friend, and on the day of the crime, they did not see any suspicious people who went to Room 502 of Unit 3.

To sum up, judging from the current situation, the deceased Tian Yang is very much like a suicide, and there is no possibility of murder, but despite this, everyone feels that this case is very strange, giving people a very awkward feeling, no matter how you look at it, it doesn't look like suicide.

First, there are many ways to commit suicide, such as jumping off a building, jumping into the sea, cutting your wrists, etc., but when no one commits suicide, they will choose to stab themselves in the heart, and it takes a lot of courage and pain to choose this way to commit suicide.

Second, assuming that Tian Yang really committed suicide, then why did he send a message to Jin Enpei before he died, and also sent a very strange photo, why did he do this? The photo he sent to Jin Enpei was not a selfie at first glance, but was taken by someone else, so who could be the person who took the photo?

Third, it is the door of room 502, when Xu Lang arrived at the scene, the door was hidden, why was the door hidden instead of closed, this is not a rural area, there is no habit of people not closing the door at home, is it because Tian Yang decided to commit suicide and wanted others to discover their bodies earlier?

Fourth, it is the open computer on the desk of the deceased before he died, when Xu Lang and they arrived at the scene, the computer screen was only in a dormant state, not a shutdown state, Li Lei When they were investigating the scene, after waking up the computer host, they found that the computer screen was occupied by a photo, which was a bloody and terrifying photo, a person was hit in two by a car, the upper body was lying in a pool of blood, and the lower body was rolled under the wheel of a photo, after the photo was enlarged, It was found that the deceased was a woman, according to the identification of the deceased's face, and the girl in the photo of the deceased Tian Yang's house was the same person, if Tian Yang wanted to commit suicide, why would it be this photo on his computer desktop?

It can be seen from this that this is not a suicide case, but a suicide scene that someone carefully disguised and arranged, of course, these are just speculations, and if you want to prove that Tian Yang is not a suicide, but a murder, you still need evidence to prove this.

After some discussion, everyone thought of one person, that is, Duan Yiling, the first love of the deceased Tian Yang, if you want to figure out all this, you must first check Duan Yiling, and if you want to check Duan Yiling, you have to check the car accident a year ago.

So, Ning Yanran divided the people into three groups, one group to investigate Tian Yang's life, one group to investigate the dead person Duan Yiling, and one group to continue to investigate the death scene to see if there were any other discoveries.

After having the direction of investigation, everything was going in an orderly manner, because Zhang Lei went to follow up on Song Yongde's case, so what was supposed to be done by Zhang Lei was done by Ning Yanran himself.

At the case analysis meeting, Xu Lang didn't put forward any opinions, just listened silently, when Ning Yanran specifically asked Xu Lang if he had any ideas before giving the order, Xu Lang shook his head and said no, which made everyone feel a little strange, especially Ye Xuefei, who was very concerned about Xu Lang's movements, she showed a surprised expression at the pre-case analysis meeting for the first time, of course, this expression was only fleeting, and was quickly hidden by her.

After the meeting, Xu Lang followed Ye Xuefei to the dissection room, Ye Xuefei was wearing a white coat, gloves and a mask, standing in front of the dissecting table, looking at Tian Yang who was lying quietly on the cold dissection table, while Xu Lang stood aside, his hands around his chest, one hand touched his chin, frowned, and a pair of eyes stared at the wound on the deceased's chest.

The corpse lost too much blood, the skin became pale, and the flesh of the wound turned out was also pale, looking at all this, Xu Lang's brows became tighter and tighter, and finally, after Xu Lang looked at it for a while, he left the autopsy room and returned to the office area of the second criminal investigation team.

Not long after Xu Lang returned to the second criminal investigation team, the group that went to investigate Tian Yang came with news, and Xu Lang was very surprised when he heard the news.

The deceased is indeed Tian Yang, but according to the investigators' reflection, Tian Yang had disappeared a year ago, which was obtained from the mouths of Tian Yang's parents.

And all this has to start with the relationship between Tian Yang and Duan Yiling.

Tian Yang and Duan Yiling are the same age, if Duan Yiling hadn't died, he would have been twenty-four years old this year, the two were not only the same age, but also born on the same day, the same month, and the same year, when they went to college, although the two were not classmates, but they were alumni of the same school, Tian Yang studied fashion design, and Duan Yiling studied finance.

College life is incomplete without falling in love, Tian Yang and Duan Yiling also met in college, they are each other's first love, generally speaking, graduating from college means the arrival of a breakup, although not every college couple will break up after graduation, but most couples after graduating from college, they all go their separate ways, and the relationship naturally broke up, but Tian Yang and Duan Yiling did not break up, not only did they not break up, but the relationship between the two became better and better.

After graduation, Duan Yiling went to work in a financial company, and Tian Yang went to work in a clothing design company, Tian Yang is a more introverted boy, honest, shy, kind, and a little homely, his only hobby is to like to stay at home and surf the Internet, which not only Tian Yang's parents know, Tian Yang's classmates and roommates, including his colleagues after work, can prove it.

When he was in school, Tian Yang's life was very regular, he went to class when he should go to class, ate when he should eat, and after returning to the dormitory after class, he stayed in the dormitory to play with his mobile phone, chat and surf the Internet, and he and Duan Yiling met through chatting.

After graduation, Tian Yang's life is the same, he goes to work early every day and goes home from work, in addition to finishing the work at hand, he stays at home and stays at home, because he has not irradiated Yangguan for a long time, so Tian Yang's skin is very white, a sickly white, which Ye Xuefei also found out during the autopsy.

Tian Yang's disappearance in the mouths of Tian Yang's parents has to start from a year ago.

When Tian Yang and Duan Yiling were in love, both parents knew that Tian Yang had taken Duan Yiling home and showed the girl to his parents, Duan Yiling also took Tian Yang home, and the parents of both sides also met, and both parents agreed that the two people were together, so the parents of both sides met and discussed the marriage of the two people, Tian Yang and Duan Yiling were naturally very happy, just when they were discussing which photo studio to go to to take wedding photos, an unfortunate thing happened.

A year ago, on the way home from work, Duan Yiling said that the bus she was riding collided with a crockpot truck, and there was a car accident, and Duan Yiling, who just got off the bus, was hit and killed on the spot, and the death was particularly terrifying and bloody.

Duan Yiling's death not only made Duan Yiling's mother grief-stricken, but even Duan Yiling's boyfriend Tian Yang was grief-stricken.

After the car accident, the police immediately intervened in the investigation, and after some investigation, it was found that the car accident was an accident, although the driver of the crockpot truck hit and killed someone, but it was a negligent death, so the driver was sentenced to seven years in prison, and Duan Yiling's mother was compensated, and Duan Yiling's mother also got the compensation, and the car accident and Duan Yiling's death ended like this.

However, after the investigation of the car accident was clear, Duan Yiling's aftermath was also dealt with, and less than a month after Duan Yiling's death, Tian Yang suddenly disappeared.

Tian Yang first took a long vacation for half a year with the company, the reason was to go out to study for a period of time, and the leaders of Tianyang Company all knew the news about the death of Tian Yang's girlfriend in a car accident, and everyone was very sympathetic to this introverted and shy boy, so the company approved, that is, at that time, Tian Yang disappeared from everyone's field of vision.

After Tian Yang left the company, he not only disappeared from the field of vision of his colleagues, but also did not contact his parents again, but also cut off contact with relatives and friends.

Speaking of Tian Yang's disappearance, all people who know Tian Yang feel very strange, not only strange, but also a little taboo, many people who have known Tian Yang before, don't want to say, in the police investigation, after doing some ideological work, they told the police that after Tian Yang's disappearance, although he did not appear in everyone's field of vision, but his buckle is often updated, not only Tian Yang's buckle dynamics will be updated, but there are also many messages in the space message board of the dead Duan Yiling.

First of all, in the message board of Duan Yiling's buckle space, they found that Tian Yang went back to leave a message every day, and the content of the message was very sensational and touching, all of which were Tian Yang's expression of his longing for Duan Yiling.

Secondly, it is Tian Yang's buckle dynamics, after Tian Yang's disappearance, every button dynamic he released was very strange, as if it was not sent by him, but the habit of the dead Duan Yiling to post dynamics before his death, at the beginning, those dynamics released by Tian Yang, people who knew both of them also liked and commented and the like, thinking that this was Tian Yang commemorating the deceased Duan Yiling in a special way, but, after a long time, Tian Yang always released these things, and after they saw it, they felt weird and a little panicked.

Then, Tian Yang often uploads some selfie photos, every time these selfie photos are uploaded, there is a red box on the photo, at the beginning, others don't think there is anything, but, what makes people feel strange is that every time these photos with a box are uploaded, the next day after uploading, at the same time, these photos with a box will be deleted, and then re-upload a photo without a box.

In the face of this situation, combined with the buckle dynamics released by Tian Yang, everyone felt a little creepy, at the beginning, some people chatted with Tian Yang privately, asking him why he released these strange things, Tian Yang told these friends what he had said to Jin Enpei, now is the era of science, in the face of this kind of supernatural thing, some people think that this is someone is playing pranks, some people think that this is a hacker playing Tian Yang, and some people think that Tian Yang died suddenly in his first love girlfriend Duan Yiling, and he was mentally hit hard. There was a mental illness, so some well-wishers comforted Tian Yang through the buckles, telling him not to think too much, and some people directly blacked out Tian Yang's buckles, but in the face of everyone's concern, whether it was Tian Yang's buckle dynamics or space photos, it was still so weird and terrifying, over time, many people no longer comforted Tian Yang, silently deleted his friends, or directly blacked out his buttons.

The police are not surprised by their approach, after all, every time someone in the space always posts something in the tone of a dead person, their hearts will be furious and they will shudder.

And when Tian Yang reappeared in everyone's field of vision, it was more than a month ago.

In the face of Tian Yang's appearance, the happiest must be Tian Yang's parents, but after Tian Yang came back, he only went home once, only ate one meal at home, and then left, neither explaining to his parents where he went and what he did after disappearing for nearly a year, nor did he continue to live with his family, and he didn't even sleep at home for one night.

Tian Yang's parents knew that Tian Yang had rented a house outside, but they didn't know exactly where they rented it.

After Tian Yang came back, he first went to the company and continued to go to work and leave work every day, living a 9-to-5 life.

After Tian Yang came back, many people did not dare to approach Tian Yang, because they didn't know what happened to Tian Yang during that period, but after the initial discomfort and suspicion, they found that Tian Yang was still the same Tian Yang before, no different from before, so they gradually relaxed and continued to work with Tian Yang.

After getting the news, Xu Lang asked the members of the team investigating Tian Yang's interpersonal relationships to carefully ask Tian Yang's parents and friends, asking them if they knew where Tian Yang had gone and what he had done since Duan Yiling's disappearance a month after his death.

Actually, they didn't need Xu Lang's orders, they did the same, but the result was disappointing, everyone didn't know where he went and what he did during the days when Tian Yang disappeared.

After listening to the report, Xu Lang thought of a detail, that is, the time when Tian Yang reappeared after being missing for nearly a year, August 11.

August 11th is the day when Tian Yang contacted Jin Enpei of the Langge Detective Agency, and it is also the day when Tian Yang appeared, and it is the second day of the 810 case.

Thinking of this, Xu Lang's heart became more and more strange, why did Tian Yang choose to appear on this day? After he appeared, why did he contact Jin Enpei in the first place? Or rather, why did he contact Lang Ge Detective Agency?

According to what Tian Yang said to Jin Enpei on the buckle, and the things told by relatives and friends around Tian Yang, there are many similarities between the two, and most of them are the same, the only difference is that Tian Yang's buckle dynamics are released in Duan Yiling's tone, and the photos in Tianyang's space are also the photos that were marked first, and then deleted and re-uploaded normal photos, which is different from Tian Yang's narration to Jin Enpei.

Thinking of this, Xu Lang asked Lu Xing to find a way to log in to Tian Yang and Duan Yiling's buckles, to see what is in it, which one is the truth of the matter, only by figuring out this, can we continue to investigate, otherwise, it is cloudy and foggy, and it is difficult to figure out the truth of the matter only through other people's narration, after all, when people tell a thing, it is easy to mix personal subjective emotions in it,
