There is a river in the center of HK city called Yingchun River. There are a total of three bridges over the river, one of which is called Lang Bridge, which is a pedestrian bridge, which is designed in a wavy shape, because the neon lights often appear blue at night, so the local people call it the Blue Bridge!

The long night passed, and shortly after sunrise, a diligent cleaner aunt got up, dragged her cleaning utensils, and began to clean up the garbage and dust from the streets very early. Now in the city, the quality of people is much higher than before, like a lot of dirty and smelly garbage is not much thrown away, either taken away or thrown into the trash, so the aunt's work is slightly easier than before, she is mainly to remove the dust, leaves, and a small amount of solid waste on the roadside.

The aunt moves quickly, and she must complete the cleaning of the main road before the rush hour, otherwise it will be crowded with people and vehicles, which will not be safe for her, and it will also affect the traffic. She cleaned diligently, and finally cleaned the area she was responsible for. However, her work is not yet complete, she needs to follow the road all the way to the top of the Blue Bridge, and pick up the bottles, cans and other things that can be recycled in the trash can, so that they can be recycled and reused, which is also a contribution to the cause of environmental protection.

Seeing that today's work should be over, the aunt finally came to the blue bridge, and there was a garbage can at the head and end of the bridge. She first checked the one at the head of the bridge, which was relatively empty, with few things and nothing to recover, so she walked towards the end of the bridge. When the aunt saw the garbage can at the end of the bridge, she suddenly found that something was not quite right, just now the bridge was very clean, why did she get to here so much garbage? She saw that next to the garbage can, there were a lot of black things, and the small cart that she was still worried about must not be able to put down. She walked over and gently flicked it with the broom in her hand, but found that the thing was very heavy and couldn't be moved, so she had to step forward and untie the big black plastic bag with her own hands.

The moment the big black bag opened, a head was exposed, and its eyes were closed and lifeless. There was actually a person in it, and the aunt held on to the trash can tightly, barely allowing herself to fall. She realized that something very serious might have happened and immediately called the police with a trembling hand.

Chen Tianyu, who was sitting in Hong Kong, soon received a police report that a male body had been found on the Blue Bridge, and this person did not have any identity documents on him, but some onlookers recognized this person as seeing him on TV and in news reports, as if he was Ji Zhuo, the deputy director of the Education Bureau. Later, the police also found his photo for comparison, and notified the leader of his unit to verify, sure enough, it was Ji Zhuo, and the police at the scene knew that this person was related to the case of the Grim Reaper, so they notified the Beiting Detective Agency.

Chen Tianyu was a little surprised, he asked Li Yiting and Liu Zichen to withdraw from the protection of the community and go to find Shen Mingyue, just because he felt that the protection here was already very strict, and the police had also increased the control around him, but it backfired, and it was another life, which made Chen Tianyu very shocked. Regarding the prophecy of the so-called god of death, Ji Zhuo in the middle could not escape the "fate", Chen Tianyu immediately dispatched Xu Jingnan to personally go to the scene to pick up Ji Zhuo's body for examination.

Xu Jingnan first searched the scene, that is, near the end of the Blue Bridge, and did not find any clues, so he conducted a preliminary examination of Ji Zuo's body at the scene, and to his surprise, Ji Zuo did not die of external force like the previous deceased, his whole body was intact, there were no wounds, and there were no signs of bleeding, and the cause of his death was very simple, it was poisoning!

To further confirm the results, he brought the body back for further autopsy and laboratory tests. After several hours of expedited testing, Xu Jingnan finally found the cause of Ji Zhuo's poisoning, which was cyanide poisoning. However, in addition to this, Ji Zhuo also inhaled a large amount of carbon monoxide, which also led to his poisoning. In other words, Ji Zhuo was poisoned by two kinds of poison at the same time, and both of them can kill people.

Chen Tianyu was puzzled, and the cause of Ji Zhuo's death made him feel very incredible, because this was the only case that obviously could not have been a natural death, but pure murder without any disguise. From Ji Zhuo's body, it can be clearly told to the police that he was murdered, and the strange thing is that only one of these two situations is enough for the murderer's goal to be achieved, and why do you want to do it both at the same time, isn't this an extra move?

Hearing about Ji Zhuo's death, Xiao Guoyuan knew that she had made a big mistake, she let the target out of her sight, and finally led to the death of the target person, which is a big taboo for stalking, although she didn't dare to face it, but she also knew that she shouldn't escape, so she took the initiative to return to the Beiting branch and face Chen Tianyu.

Of course, Chen Tianyu was also planning to look for her, because Ji Zhuo had obviously been dead for a while, but Xiao Guoyuan had never reported that she had lost Ji Zhuo, and she had an unshirkable responsibility no matter what, so Chen Tianyu was very angry and asked gloomily, "What the hell is going on? The person you monitor is dead, and you yourself still know about it behind the police!"

Xiao Guoyuan drooped his head, very remorseful, and his mood was also very low, "I'm sorry, fourth brother, I, I couldn't watch Ji Zhuo." ”

"Of course I know this, I'm asking why you didn't watch it?Also, did you notice anything abnormal?" Chen Tianyu was already quite angry, but he was still trying his best to suppress his temper.

Xiao Orchard, whose self-confidence was hit by a huge blow, was a little confused, she just said that because she relaxed her vigilance, she wandered around the community, and when she returned to Ji's house, she found that Ji Zhuo was gone, she was going to look for it, but Ji Jing didn't let her go, saying that her father had an urgent matter to go to the unit, and she would come back after a while. As a result, Ji Zhuo never came back, and Xiao Orchard didn't pay enough attention, and when she felt that something was wrong, she had already received bad news.

After hearing this, Chen Tianyu became even more angry, if it was because of his young age and lack of experience, it would have been forgotten, but it turned out to be the dereliction of duty of the small orchard. The little girl's laziness at work and her lack of mental attention to the task of monitoring led to the most serious consequences. However, he still saw that the little orchard was still small and took the initiative to admit his mistakes, so he didn't want to pursue it for the time being, so he asked her to go back and think about it first, and see if there were any details to forget.

At the same time, the police also notified the family of the deceased Ji Zhuo, and his daughter Ji Jing, who was also the only remaining daughter of the Ji family, was the bad news, and asked her to rush directly to the Beiting branch to cooperate with the investigation. After Ji Jing arrived, before Chen Tianyu could speak, she had already prepared her words, and directly said her thoughts, that is, the murderer of Ji Zuo, must be the husband and wife's concubine Ding Jiayi!

It seems that the Ji family knew about Ding Jiayi's existence early on, and this matter was originally understood and suppressed by Ji Zhuo and Hou Hong's parents, and they didn't want Hou Hong, especially Ji Jing, to know, for fear of affecting the atmosphere of their family. Over the years, Ji Zhuo has been secretly having trysts with Ding Jiayi, never letting people meet him on the surface, let alone letting Hou Hong have a chance to get close to Ding Jiayi, but what he didn't know was that the smart Hou Hong noticed the abnormality from the clues, and heard about his parents and knew Ji Zhuo's past.

However, Hou Hong did not expose the matter, after all, the ugliness of the family should not be publicized, and the relationship between her and her husband is also very clear, but it is just a dragonfly and respectful of each other, as long as Ji Zhuo does not do anything too out of line, then outside, Hou Hong does not want to make a fuss, which will have a negative impact on her family, parents and daughter. Therefore, Hou Hong has always taken a strict and fearless attitude, and she is not worried that Ji Zhuo dares to divorce herself and be with Xiaosan, in that case, it will be a devastating blow to Ji Zhuo's career, reputation and all achievements, so Hou Hong means that as long as the family is complete, as long as she is still the mistress of this family, she will try her best to calm things down.

But as a daughter, as a simple girl who has just entered the society, Ji Jing's thoughts are completely different. She has a great sense of justice, and when she learned about her father's private affairs, she was immediately very dissatisfied with her father, which was also the main reason for the breakdown of her relationship with Ji Zhuo.

Ji Jing couldn't bear her father's betrayal, let alone her mother's grievances, so without Hou Hong's permission, she still conducted a very private investigation of her father's affairs in private. First of all, she found out that Ji Zhuo and Ding Jiayi did not hook up recently, but they had known each other for a long time, as early as before they had themselves, that is, the so-called childhood sweethearts, and later they were forced to separate for some reason, Ji Jing herself sympathized with her father, but she thought that since her father and mother were married together, she should not have any contact with her past girlfriend, not to mention the part of finding a lover, which was a heavy blow to Ji Zhuo's identity and father's image, so she couldn't accept it. Subsequently, Ji Jing, who couldn't stop, launched a comprehensive investigation of Ding Jiayi, she wanted to understand the true situation of this woman, so as to find a way to persuade her father to turn back, and she could also search for evidence and maybe help her mother recover her losses in the future.

As Ji Jing continued to investigate, she found that Ding Jiayi was not as simple as she behaved by her father's side, but her style was very problematic. Ding Jiayi and Ji Zhuo's time alone together is very limited, in more time, Ding Jiayi lives alone, but he can't bear to be lonely, according to Ji Jing's own eyes, there are at least two other men who have improper intimate relationships with Ding Jiayi, and without Ji Zhuo's knowledge, Ding Jiayi often goes in and out of some bars, nightclubs and other places, and these places, Ji Zhuo can never go. Therefore, Ji Jing believes that Ding Jiayi is actually a watery poplar woman, and her father was deceived by her appearance and nostalgia for the past.

Ji Jing's evaluation is very different from Ji Zuo, Chen Tianyu feels a little incredible, not to mention Ji Zuo's rich experience, he should not be deceived like this. And Ding Jiayi is the first love of her childhood sweetheart, this is not like the woman she met halfway, their previous relationship is unlikely to be tarnished, not to mention that Ji Zhuo has always been very good to Ding Jiayi, and there seems to be no major contradiction between the two.

Chen Tianyu felt that when Ji Jing said this, in addition to seeing Ding Jiayi and the man outside, there must be an inside story, "Ji Jing, I know that it is very difficult for you now, but we can't tell who the murderer is based on what you say, if you say that Ding Jiayi is suspicious, you must tell me, is there any inside story?"

Hearing such a question, Ji Jing, who had a deep opinion of Ding Jiayi, hesitated, and her dilemma seemed to be unspeakable.

"If there is no special evidence, then as a single woman, whether it is pulling with a man, or going to a bar or nightclub, this is a personal habit, even if it is a bad thing, but it cannot be regarded as a mistake, let alone speculated as a motive for the crime, do you understand what I mean?" Chen Tianyu continued to persuade.

"Well, in fact, I said that there is a problem with her style because I know one thing," Ji Jing paused, and made up her mind to say it, "Tong Minghai, do you know? Ding Jiayi and Tong Minghai have a personal relationship, I have seen it with my own eyes!"

This is really an amazing secret, Tong Minghai was begging Ji Zhuo for his daughter Yangyang when she was in school, and he actually dared to secretly communicate with his lover in secret, which made Chen Tianyu feel that things were suddenly even more confusing. Tong Minghai, Ji Zhuo, and Liu Changshou, their direct and intricate relationship can be described as one after another, interlocking, and the only thing they have in common now is that they are all no longer alive.

The development of things made Chen Tianyu can't help but fall into a dilemma, is his judgment wrong?

He stood up and walked back and forth in the room, the dead, the witnesses, and the clues, all colliding and intertwining in his mind. Suddenly, Chen Tianyu thought of a situation that he had never imagined, could it be that the whole thing was a conspiracy designed by Tong Minghai and Ding Jiayi who were in love with each other and had a heated relationship? It's just that there was an accident in the middle of the way, and Tong Minghai made a mistake in designing, but he gave his life first. Because of this, Ding Jiayi launched a series of revenge under her pain, thus committing a series of subsequent murders.

Chen Tianyu understood that this idea was formed based on Ji Jing's testimony, and the prerequisite was to prove that what she said was true, that is, Ding Jiayi did have a personal affair with Tong Minghai. But even so, the grievances between them and Erri and Liu Changshou are still unknown, and things are still confusing.
