When Ning Yanran and the others walked to Lu Ye's side, and saw the handwriting on the blank paper, everyone's eyelids jumped three times subconsciously, Xu Lang's sister Xu Chan was killed, although the police officers in S City knew that before, when Xu Lang had not yet entered the public security system, some people would occasionally mention it, but since Xu Lang entered the public security system, no one has mentioned this matter, even Wu Yong, who has never been very eye-to-eye with Xu Lang, this matter can be said to be a taboo of the Public Security Bureau. Although, in the past ten years, the police have not given up investigating the matter, but so far, nothing has been found.

Ning Yanran didn't expect that after a lapse of ten years, when it was about to be the eleventh year, someone would write such a note to Xu Lang, and it can be seen from the lines of that sentence that the person who wrote this letter is likely to be the murderer of Xu Lang's sister back then, which made everyone have a doubt after seeing the provocative challenge letter.

Xu Lang's sister Xu Chan was killed in the summer of 1999, and now it has been ten years, and the police have not found any clues related to the murderer, although in this ten years, the suspects have been suspected as many as hundreds, but, after the police have questioned and investigated again and again, these people have been ruled out one by one, since the police have not found clues related to the murderer, it will take a long time to catch the real murderer, then, Why did this murderer appear at this time?

Since Xu Chan was killed, S City and several cities around S City, there have been no similar cases, although in the past ten years in the country, there have been more than a dozen similar cases, but the murderers in these cases have almost been arrested, most of them have been executed, and every time this kind of similar case occurs, the police in S City will rush to the local area, interrogation of the suspects, every time they go with great hope, but every time they are disappointed.

Since the murderer of Xu Chan has not committed a crime in the past ten years, it means that the other party is not a perverted serial murderer, ten years ago, the police's investigation methods and technical conditions were not perfect enough, so many cases at the scene of the year could not be protected as well as now, the current police, whether in the investigation methods, or in the technical equipment, are very advanced, as long as the murderer commits the crime again, then, It's only a matter of time before the police want to find him, but in the past ten years, the murderer seems to have evaporated from the world, and no similar cases have been committed, which also makes the investigation of Xu Chan's case slow down.

Why did the killer do this?

This is a question that everyone is very confused about, is it just that they want to play a game with Xu Lang? If that's the case, isn't the price of the game a little too much? Now there is a human hand on Xu Lang's desk, although it is said that with only one hand, it is impossible to judge whether the owner of this hand is Jin Enpei, whether the other party is still alive, even if the other party is not dead, so what is the difference between losing a right hand, especially a woman, and life is worse than death?

If it is to provoke Xu Lang, it is unreasonable, if the murderer challenged Xu Lang when Xu Lang entered the second criminal investigation team and when Xu Lang became a criminal investigation star, it is reasonable, but now that Xu Lang has left the public security system and is no longer a criminal policeman, why should the murderer challenge Xu Lang, who is not a criminal policeman? And what is his purpose in doing this?

Could it be revenge? For this situation, for the criminal police and anti-narcotics police who have been rushing to the front, it is also normal for the prisoner to retaliate, like the murder of Li Chenghua, when his body was found, the first thing the police thought of was the special person with a bad record, and the revenge against him, is it the same for the package Xu Lang received now?

Ning Yanran and they looked at Lu Ye with these doubts, after all, Lu Ye is an old criminal policeman who has struggled in the public security system for decades, a person who has experienced strong winds and waves, after the initial shock and anger, he gradually calmed down, he put down the challenge book in his hand, looked at Xu Lang, who had been silent, Lu Ye coughed lightly, and said: "Ahem, Xu Lang"

It's just that before Lu Ye's words were finished, Xu Lang said in a low and hoarse voice: "Uncle Lu, I'm fine, you can investigate how you want, and everyone in the detective agency will cooperate with your investigation." ”

Lu Ye, who was originally very worried about Xu Lang, and the members of the second criminal investigation team, after hearing Xu Lang say this, their hanging hearts gradually relaxed, to be honest, they were really afraid that Xu Lang would do something crazy after receiving the challenge, Xu Lang went berserk, there was a precedent before, and more than once, but now it seems that after Xu Lang left the public security system, he has become a lot more mature and stable, which is what makes Lu Ye very happy.

Since Xu Lang opened his mouth to speak, it means that he is still relatively calm, Lu Ye glanced at Xu Lang deeply, then stretched out his hand and patted Xu Lang's shoulder, then turned his head and said to Ning Yanran: "You come out with me." ”

After Lu Ye finished speaking, he took the lead in leaving Xu Lang's office, while Ning Yanran hurriedly followed out, and the others began to investigate step by step.

After Lu Ye walked out of Xu Lang's office, he took out a box of cigarettes from his pocket, lit a cigarette, looked at Ning Yanran and asked, "You should know about Sister Xu Lang, right?" ”

Ning Yanran nodded, groaned for a while, and said, "When I was in the Provincial Public Security Department, I heard my father talk about it. ”

Lu Ye nodded, not asking Ning Yanran how much he knew, after all, Ning Yanran's family background was not ordinary, which was different from the rest of the second criminal investigation team, Lu Ye spit out a puff of smoke, then looked at Ning Yanran, and said seriously: "This case is temporarily in charge of your second criminal investigation team, you must find out about this matter, if you determine the owner of that hand, see if the other party is still alive, if the other party is still alive, you must rescue her, if"

Lu Ye said this, paused, and then continued: "If the other party has been killed, then, your second criminal investigation team must arrest the real murderer, and after you go back, I will let the first criminal investigation team cooperate with you in investigating this case." ”

After hearing Lu Ye say this, Ning Yanran nodded silently, she didn't say anything about the murder case must be solved, how long it will take to solve the case, no matter how impassioned the words are, they are all nonsense, only by catching the real murderer early can this matter be truly solved.

After Lu Ye saw Ning Yanran nodding, he took a puff of cigarette and directly finished the remaining two-thirds of the cigarette in one go, and then, Lu Ye spit out a thick puff of smoke.

Ning Yanran was just about to go back to assign tasks, she turned around, glanced in the direction of the office, and found that Xu Lang was still sitting on the office chair, Ning Yanran hesitated, turned her head and asked Lu Ye: "Lu Bureau, that Xu Lang"

Ning Yanran's meaning is obvious, she is asking Lu Ye whether Xu Lang should be involved in this case, after all, this time the murderer is challenging Xu Lang by name, and this murderer is likely to be the murderer who killed Xu Lang's sister ten years ago, Ning Yanran is worried that Xu Lang will behave abnormally.

Lu Ye pondered for a while, thought about it, turned his head, looked at Xu Lang's young face, and then nodded and said: "As for Xu Lang, let him be involved in this case, after all, the murderer is targeting him this time." ”

"Land Bureau, in this way, I'm worried"

Before Ning Yanran's words were finished, Lu Ye waved his hand, interrupting what Ning Yanran was about to say, his eyes were firm, and he said in a calm tone: "I believe in Xu Lang, you should also believe him." ”

"But"

Ning Yanran wanted to say something, but Lu Ye waved his hand directly, turned to leave, and said before leaving: "Xu Lang was grown up by me, no, this matter was decided." ”

Ning Yanran looked at Lu Ye's slightly lonely back, frowned, and then, she turned her head again and looked at Xu Lang in the office, when she turned around, she found that Xu Lang was also looking at her, and the two of them looked at each other, speechless.

After Lu Ye left, the people of the second criminal investigation team started to work according to the process, first, they asked people to send the box containing the human hand back to the forensic office of the Public Security Bureau, and also extracted Jin Enpei's biological sample on Jin Enpei's desk, and the two were sent to the technical department for DNA comparison to see if the human hand was Jin Enpei's own, and secondly, according to the address information filled in the express list, the investigation and visit were conducted, and the challenge book and the express box were sent to the technical department for fingerprint identification. See if you can find suspicious fingerprint clues on it.

Just when Ning Yanran was in full swing to arrange her work, Shu Yue came to the detective office, she was busy in her own company, after receiving a call from Du Ziqiao, as soon as she heard that Xu Lang had an accident here, she hurried over, when she came to the detective agency and saw that there were uniformed policemen coming in and out, Shu Yue's heart suddenly rose, she walked quickly to Xu Lang's office, when she saw that Xu Lang was fine, her hanging heart was relaxed, but, When she saw that Xu Lang's hands were blurry and still dripping blood, she was distressed and sad.

After Shu Yue walked into Xu Lang's office, she came directly to a bookcase, opened the drawer inside, took out a simple medical box from it, and then walked to Xu Lang's side, she first used a cotton swab to clean up the blood stains on the back of Xu Lang's hand, and then disinfected it with alcohol, and then applied some medicine powder to treat trauma, and finally, used gauze to bandage Xu Lang's wound.

When the wound on the back of Xu Lang's left hand was cleaned up, Ning Yanran and the others found that the white bones could already be seen at Xu Lang's knuckles, which shows how much strength Xu Lang exerted when the punch was punched out just now, and Xu Lang is now sitting on the chair like no one, when Shu Yue used alcohol to clean his wounds, Xu Lang didn't even frown, which shows how strong Xu Lang's endurance is.

After Shu Yue did all this, she didn't ask Xu Lang directly what was wrong, but stretched out her hand and touched Xu Lang's forehead, and said in a somewhat reproachful tone: "You, you're twenty-five or sixteen, why are you still like a child, and you are still so impulsive when you encounter things?" ”

Hearing Shu Yue's voice, Xu Lang's unfocused gaze focused a little bit, turned his head, looked at Shu Yue with a wry smile, and said slightly apologetically: "I'm worried about you." ”

Shu Yue shook her head, didn't say anything, and didn't ask anything.

In fact, when Shu Yue was cleaning Xu Lang's wound and bandaging it, she learned what happened from the police officers walking back and forth around the air, although it was not the whole story, but Shu Yue knew what was going on with a little brain supplement, when she heard that the murderer who killed Xu Lang's sister Xu Chan ten years ago appeared again, her originally calm face suddenly became difficult to see, but she still didn't say anything after all.

After Ning Yanran saw Shu Yue coming, seeing her virtuous appearance, Ning Yanran was a little envious of Xu Lang, she could find such a virtuous and reasonable girlfriend, but the investigation that should have been carried out must still be carried out.

Ning Yanran and they made interrogation records for all the members of the detective agency, including Xu Lang, according to the usual practice, and now there is no Jin Enpei in the Langge Detective Agency, and there are only four people plus Xu Lang.

Xu Lang explained everything from receiving the express package to discovering the human hands in the package, as well as Jin Enpei's watch and the challenge letter, and Ziche Hexuan, Liao Yi, Du Ziqiao and others also told the police what they saw and heard.

After Du Ziqiao contacted the police and Shu Yue, he dialed Jin Enpei's mobile phone as soon as possible, but the result was worrying, because Jin Enpei's mobile phone was turned off, I don't know if it was because the phone was automatically turned off when it ran out of power, or because the murderer turned it off, Jin Enpei's watch was sent to Xu Lang along with the package of the corpse, and Jin Enpei is now out of touch, which has to make people think about the worst.

After Ning Yanran and the others finished making a record for Xu Lang, they immediately asked people to find the courier brother who sent Xu Lang today, and at the same time, Ning Yanran and they returned to the Public Security Bureau with everything, and Xu Lang also went with them.

Before leaving, Xu Lang took a deep look at Du Ziqiao and didn't say anything.

And after Du Ziqiao saw Xu Lang's eyes, he nodded heavily and said to Xu Lang: "I am here in the office, don't worry, I know what to do." ”

Xu Lang patted Du Ziqiao's shoulder, then looked at Shu Yue apologetically, Shu Yue smiled, shook his head at Xu Lang, walked up to Xu Lang, helped Xu Lang tidy up the neckline of his clothes, and said gently: "You go and do what you should be busy with, don't worry about me." ”

Hearing Shu Yue say this, Xu Lang left the detective agency.

After Xu Lang and the police left, Du Ziqiao looked at the messy office and said directly to Ziche Hexuan: "Hexuan, the company has Jin Enpei's home address, you can find Jin Enpei's resume now, and follow the address to Jin Enpei's house." ”

Then, Du Ziqiao said to Liao Yi again: "You go to the Internet to check, all the things related to Jin Enpei, we can't just rely on the police, we also have to move, after all, Jin Enpei is a member of our detective agency." ”

Hearing Du Ziqiao's arrangement, Ziche Hexuan and Liao Yi both nodded one after another, without any opinions, although they didn't get along with Jin Enpei for a long time, but, Jin Enpei is a beautiful and intellectual woman, and she is usually very good to them, now, Jin Enpei is very likely to be killed, as colleagues, they should all do their best, if Jin Enpei is not killed, then find her earlier, the sooner you can rest assured, if Jin Enpei is dead, then it is best to find her body earlier, so, Everyone in the Lang Ge Detective Agency began to investigate Jin Enpei.

After Shu Yue and Du Ziqiao began to investigate Jin Enpei's affairs, she stayed in Xu Lang's office alone, she picked up all the documents scattered on the ground one by one, and picked up the phones that fell on the ground, as for the computer monitor, it was broken by Xu Lang's punch, it must not be used, she also packed it up and put it in the corner.

After Shu Yue did all this, she went back to her company, and then called all the customers who made appointments one by one and resigned, and now someone is deliberately targeting Xu Lang and challenging Xu Lang, as Xu Lang's woman, at this time, since she can't help much, then, she has to help Xu Lang stick to the rear, and give Xu Lang the best support and help when necessary.

Xu Lang sat in the co-pilot of Ning Yanran's police car, he put his hands around his chest, looked out the window, thinking about things, after the initial anger and excitement, Xu Lang gradually calmed down, Xu Lang knew very well in his heart that anger could not solve anything, after anger, he lowered people's IQ, and since the murderer who gave himself a challenge book dared to give himself a war book openly, then, he was very likely to be near him, monitoring his every move, if he really made any outrageous moves, That is in the hands of the other party, the reason why the other party did this is to provoke Xu Lang, Xu Lang is not a fool, he naturally wants to get all this, he can't let the other party succeed, now, Xu Lang thinks again, the person who sent him the courier will be the person who has been around him before, monitoring himself, if it is really the other party, then who is this person, why did he do it? All this has created a huge question mark in Xu Lang's heart
