The principle of the police is not to believe in coincidence. Ninety-five percent of criminal investigation work is done in the office, analyzing evidence, writing criminal records, interrogating witnesses, and so on. We often see in crime-solving films that the murderer confesses when he is scared loudly, but in reality it is not so simple. When a person is found next to a corpse with a bloody knife, he can be identified as a murderer. A sane policeman would not believe that he was passing by and helping the deceased pull a sharp knife out of his body. The maxim of the criminal detective is that the ending that is too simple is a playwright's fabrication. The opposite is even more true. What is obvious to all is often highly probable, and it is almost true. ———— Ferdinand von Schirach

In the conference room of the Public Security Bureau of S City, there were more than a dozen people sitting unevenly, most of these people were comrades from the Second Criminal Investigation Team and the Chengxi Criminal Investigation Detachment, in addition, Lu Ye was also at the scene, as well as comrades from the Technical Department.

Lu Ye sat in the first place, his face was very solemn, this year, only half of the time has passed, and there have been three major cases that shocked the city and even the whole province and the whole country, Jin Enpei's case, Bu Zimo's case, and now the orphanage case, each case has made the police pay a great price, Lu Ye feels a deep exhaustion at the moment, in addition to physical and mental exhaustion, more is mental exhaustion.

Lu Ye feels old, he is indeed old, of course, for a person who is not yet sixty years old, in fact, Lu Ye is not old, it's just that in the past two years, there have been too many cases, which makes Lu Ye feel physically and mentally exhausted, his already somewhat dark and serious face is becoming more and more serious and dark at this moment, I don't know how much time, this old man who is not yet a sixtieth year, his hair has turned more than half white, and the wrinkles on his face are getting more and more. It seems that these gray hairs and wrinkles are meant to tell all those who see it all that he is old.

There is still a year, Lu Ye will retire, in fact, he doesn't have to retire so early, when he is sixty years old, he can be transferred to an idle position, just sit in the office every day, probably because he stays on the front line of work all the year round, he is already very tired, maybe he saw Xu Lang grow up, and saw that the second criminal investigation team and the first criminal investigation team can already take charge of themselves, he feels that he can put down the burden on his shoulders, so Lu Ye submitted an application for retirement as early as two years ago, but the superior did not approve it, and he has been pressing.

And the reason why the superiors disagreed was very simple, you Lu Ye is not yet sixty years old, why did you retire so early, so Lu Ye had to continue to stay in the position of director of the General Bureau of Public Security.

At the beginning, when Lu Ye applied for retirement, he recommended a candidate to his superiors to take his place, and this person was none other than Xu Lang.

Of course, with Xu Lang's personal ability, he is fully qualified for this position, but he is too young, less than thirty years old, and Xu Lang's political background has always been controversial, although in those years, when Xu Lang was the captain of the second criminal investigation team, the crime solving rate in S City did not dare to be said to be the first in the country, but there was no problem in ranking the top three in H Province, which was obvious to all leaders.

Lu Ye wants to retire, naturally someone needs to take the position, there are many people who agree with Xu Lang to take Lu Ye's position, but there are more people who oppose Xu Lang's position, back then, because of this incident, Lu Ye didn't know how many people he had quarreled with, scolded his mother, and his superiors were also very embarrassed, so he had to be a peacemaker, but when he was in March last year, Xu Lang chose to resign and left the public security system because of himself, and he never mentioned Lu Ye's retirement, and whether he supported Xu Lang or opposed Xu Lang before, They all chose to be silent.

Xu Lang left the second criminal investigation team and resigned as the captain of the second criminal investigation team, at that time, everyone thought that the captain of the second criminal investigation team would be replaced by Zhao Hualai, the deputy captain, although Zhao Hua's ability is not as good as Xu Lang, but his business ability is still remarkable, Zhao Hua was promoted to the captain of the second criminal investigation team, and Li Lei became the deputy captain, in this way, the second criminal investigation team is still the former second criminal investigation team, however, no one expected that the superiors would parachute Ning Yanran over and become the captain of the second criminal investigation team.

If Ning Yanran was an experienced old criminal policeman, with old qualifications, enough ability, and ability to convince the public, naturally no one would object, but what about Ning Yanran? She doesn't occupy any of them, a newcomer who has only graduated from the police academy for less than two years, has been engaged in civilian work before, has never been to the scene of the first crime, nor has she solved any cases alone, plus, she is still a woman.

At that time, Ning Yanran's arrival made Lu Ye depressed for a long time, and he found Du Yongnian, director of the Provincial Public Security Department, more than once, and raised objections, but the matter of sending Ning Yanran to serve as the captain of the second criminal investigation team was not something that Du Yongnian could decide alone, but a meeting of the superior leaders to study and decide, and it was useless for Lu Ye to oppose it.

The orders of the superiors could not be changed, Lu Ye had to change the route and go to Xu Lang, hoping that Xu Lang could return to the public security system, but Xu Lang refused, and Lu Ye could not force Xu Lang to do anything, in fact, Lu Ye, as the director of the General Bureau of Public Security, was already suspected of favoritism and fraud by doing so, and it was a matter of violating discipline, but he had stayed in the position of director of the General Bureau of Public Security over the years and had done a lot of practical things.

Since Xu Lang left, Lu Ye felt that he was old and wanted to retire early, but whenever he came home from work, he sat in the study, looked at the old photo in the past, and thought of what happened to Xu Lang's family, Lu Ye was a little sad, twenty years have passed, and the truth about the murder of Xu Lang's family has not been investigated clearly, which is an eternal pain in his heart, and it is also a regret in the hearts of people in the public security system of S City.

Lu Ye has been thinking about when he can cultivate a capable and responsible talent from the people below to take his place, and he can retire with confidence, but in the past two years, he has seen many people, Ning Yanran of the second criminal investigation team, Wu Yong of the first criminal investigation team, and the people of the criminal investigation detachment of the other four districts and the director of the public security bureau, Lu Ye has thought about it, whenever he thinks of these people, he will subconsciously think of Xu Lang's child.

However, Xu Lang left, unwilling to return to the public security system, he couldn't do anything, Lu Ye thought, anyway, there are still two or three years, and when he reaches the age of sixty, he can officially retire, as for who will sit in the position of director of the General Administration of Public Security, it will be a headache for the superiors, however, there have been so many cases in this year, although the cases have not been fully investigated, but Lu Ye knows that he may have to retire early.

Thinking of this, Lu Ye couldn't help but raise his head and look at the young man sitting opposite him, at the back of everyone, Xu Lang.

It's just that after Lu Ye saw Xu Lang, he couldn't help but think of his father Xu Yuan, and also remembered the Xu Yuan who appeared in the Bu Zimo case, and then thought of some things he knew.

Lu Ye shook his head and forcibly suppressed the troubled thoughts in his mind, today's case analysis meeting is not to discuss his retirement, nor is it the time to discuss Xu Lang, but to discuss the issue of Shangguan Watson, who is wanted by the Ministry of Public Security.

Shangguan Watson's appearance was too sudden, and his death was too hasty, everything caught the police off guard, and there were still many questions that had not been investigated clearly, Shangguan Watson died, it seems that his appearance and death were to draw a successful end to the orphanage case, no matter what the people sitting there thought, at least, Shangguan Watson thought so,' Master Chang's organization thinks so, and there are some people who hide in the dark corners and look at all this coldly, it seems that there are many people who want this to end the matter, but is it really over?

Lu Ye shook his head secretly, he didn't think that the appearance and death of Shangguan Huasheng was the end of everything, on the contrary, he thought that this was the beginning of everything.

Lu Ye thought so, and there was another person present who also thought so, and that was Xu Lang.

————

Today is October 18th, the day after Shangguan Huasheng's death.

The case analysis meeting is still the same as before, introducing the case, analyzing evidence and clues, and putting forward their own ideas and opinions.

After Shangguan Huasheng's death, the police have been tracking down the person who made the report, although through the chat between Xu Lang and Shangguan Huasheng, they knew who the whistleblower was, but the police still wanted to find the whistleblower.

However, to the disappointment of the police, the whistleblower disappeared after making the report number, without any identity information black card, no suspicious person, and the only thing left was a very short recording.

Shangguan Watson's wanted warrant reward is 300,000, what can 300,000 do? You can do a lot of things, you can buy a house in S City and pay a down payment, you can buy a slightly better car, you can use this money to start a business, you can even use this money to get married, and there are many things that can be done for 300,000 yuan, however, this whistleblower did not come to the police station to receive the bounty, which also disappointed the police's expectations of luck.

After Shangguan Watson's body was transported back to the Public Security Bureau, forensic doctor Ye Xuefei led people to start a judicial autopsy on Shangguan Watson's body, and the autopsy results had already come out and were placed in front of Ye Xuefei.

"Let's talk about the autopsy results." Lu Ye retracted his thoughts, looked at the forensic doctor Ye Xuefei who was sitting in the back row and said.

With Lu Ye's opening, the heavy atmosphere on the scene eased slightly, and everyone looked at Ye Xuefei, an iceberg beauty.

Ye Xuefei still had that cold expression, which did not change because of everyone's gaze, she glanced at Lu Ye, picked up the document in her hand, and directly reported the autopsy results of Shangguan Watson.

Shangguan Huasheng died of chemical poisoning, tri-oxy-chemical-di-arsenic, which is often referred to as arsenic-cream, died of circulatory failure caused by taking arsenic-cream, Ye Xuefei found poison residues in Shangguan Huasheng's stomach and blood, Ye Xuefei found that the mucous membrane of the deceased's stomach was ulcerated in a large area, the stomach was bleeding, and the liver was also seriously damaged.

Ye Xuefei paused, glanced at Xu Lang, who had been silent, she retracted her gaze, and continued: "According to the analysis of the filling of the deceased's stomach, the dose of poison taken by the deceased is not very large, but it is enough to be fatal, according to the analysis of the autopsy results, the deceased probably took the poison about an hour before his death. ”

"You took it an hour before you died?" Xu Lang, who had been silent, raised his head abruptly and looked at Ye Xuefei, as if he wanted to determine whether the autopsy results were correct.

Ye Xuefei was not dissatisfied with Xu Lang's occupation, she naturally looked at Xu Lang, nodded, and said, "Yes, I took it an hour before I died." ”

Hearing this exact answer, Xu Lang fell into deep thought, and everyone present also began to talk in a whisper.

Since Shangguan Watson died in the orphanage in the west of the city, Xu Lang has been thinking about when Shangguan Watson took the poison, from the moment he and the police entered the scene, everyone present has been watching Shangguan Watson's every move, and has not found that he has done any special actions during his period, let alone the opportunity to take poison, so, Xu Lang has been unable to figure it out, and now, the autopsy results are out, Xu Lang finally understands.

Shangguan Huasheng had already taken poison before Xu Lang and they arrived at the orphanage, and after he entered the orphanage, he had no intention of coming out alive, if Xu Lang reminded Xu Lang, Xu Lang would not have thought that Shangguan Huasheng would go to the Chengxi Orphanage so quickly, if the police hadn't arrived at the Chengxi Orphanage so quickly, when Xu Lang and they arrived at the scene, only Shangguan Watson's cold corpse might have been found.

The appearance of Xu Lang and the police slowed down Shangguan Watson's suicide attempt, which made Shangguan Watson very surprised, so when the police appeared, Shangguan Watson did not do anything crazy, but chatted with Xu Lang, in order not to leave the orphanage so quickly, he even placed a lot of explosives in the orphanage in advance, although, after the analysis of the technical comrades, most of the so-called explosives were actually used in fireworks, and once ignited, the explosion would definitely explode. But the power is definitely not that great, and it is impossible to be detonated by remote control, but at that time, under that special circumstance, everyone present did not notice this, even Cao Zhiyi of the Chengxi Criminal Investigation Detachment did not notice this, and it was precisely because of this that Shangguan Huasheng stayed in the orphanage and did not come out.

Xu Lang didn't feel angry because Shangguan Huasheng played himself, on the contrary, he felt more sincere admiration for this dead old man.

Shangguan Huasheng may have expected that the police would arrive in advance before taking the poison, otherwise, he would not have placed so many explosives in one move, let alone when Xu Lang and the police planned to implement compulsory measures, he leisurely took out the bomb remote control and threatened the police, it seems that this old man has thought about everything that may happen in advance, and has also taken countermeasures, which is one of the reasons why Xu Lang admires him.

And what made Xu Lang feel even more admired and even chilled was that people who took arsenic-frost would suffer what kind of pain their bodies would suffer, Xu Lang and everyone who sat down again knew very well in their hearts, the throat felt hot, thirst, nausea, vomiting, etc., these symptoms should have appeared, Xu Lang didn't show anything unusual at all when he was chatting with Shangguan Huasheng, how much inhibition and endurance is required, as well as strong body control.

During the more than half an hour of contact between Xu Lang and Shangguan Huasheng, Shangguan Huasheng behaved very calmly and calmly, like an old man who already knew his ending, chatting with Xu Lang about some things, except for smoking a few cigarettes during this period, he had no other actions, and it was precisely because of this that Xu Lang and they did not find out that Shangguan Huasheng had already taken poison.

In the past, Xu Lang thought that Shangguan Watson was just an arms dealer, a criminal cultivator, and a murderer, and he felt that he had valued the other party enough, however, now it seems that he still underestimated this old man.

Xu Lang thought of this, and a nameless anger surged in his heart, although Shangguan Huasheng said everything he wanted to know before he died, especially the identity of the nameless corpses that are still in the freezer in the autopsy room, but Shangguan Huasheng was born and died, he was not killed by the police because of arrest, nor did he die of natural old age, and he did not die after being tried by the law, but committed suicide by taking poison, which made Xu Lang very annoyed.

Shangguan Huasheng is dead, but there is no way to answer many questions related to him.

Seeing that Xu Lang was not asking other questions, Ye Xuefei continued: "When we performed the autopsy, we found a lot of scars on Shangguan Watson's body, including five scars left by bullets, but these scars were all left decades ago. ”

Everyone was not surprised by Ye Xuefei's discovery, because Shangguan Watson was not an ordinary person, he used to be an arms dealer, since he was an arms dealer, it was normal for him to be shot, and there was nothing to make a fuss about.

Just when everyone thought that Ye Xuefei had finished speaking, Ye Xuefei spoke again: "In addition, during the autopsy, we found that the deceased had serious liver cancer, which was already in the advanced stage of liver cancer, even if he did not commit suicide by taking poison, it is estimated that he will not live long." ”

"What? You said Shangguan Watson had liver cancer? Xu Lang raised his head and looked at Ye Xuefei in surprise.

Ye Xuefei nodded and said, "It's an advanced liver cancer." ”
