Xu Lang and his party came to the morgue and saw the two bodies, a man and a woman.

The body had not yet been autopsied, and after Xu Lang asked the staff for a pair of gloves and put them on, he began to conduct a preliminary autopsy, and he first examined the male deceased.

The man's pupils are dilated, his mouth is slightly open, the eyelid membrane has been clouded, his wound is on the chest, there is a one-line wound on the chest, according to Xu Lang's experience, this should be a wound left by a utility knife, in addition, Xu Lang did not find other wounds on the deceased's body, Xu Lang checked the man's fingers again, and finally found some flesh and skin tissue in the man's nails, which should be the biological sample left by the deceased before he died, scratching the murderer, Xu Lang took small tweezers and carefully took the dander out of the fingernails of the deceased and put it in a special container.

After doing all this, Xu Lang stood up, handed the container to Ding Yan, and then said: "The deceased's heart was punctured, the murder weapon should be caused by a utility knife or those knives bought at the stall as decorations, the deceased was killed after a sudden attack without the slightest defense, he should have scratched the murderer before he died, and left some biological samples in his fingernails, and after testing, you should be able to know the identity of the murderer." ”

After listening to Xu Lang's conclusion, Ding Yan nodded, he is also an old policeman, he can still see these superficial things, but the deceased's fingernails left a biological sample suspected of being the murderer, he didn't find it when he saw the corpse, which made him see Xu Lang's careful side, and Deng Zijun looked at Xu Lang with an incredible face, he really didn't expect that this man with white hair who looked a few years older than himself, It was possible to determine the cause of death of the deceased in such a short period of time, and also discover details that they had not noticed before.

After examining the body of the male deceased, Xu Lang came to the body of the female deceased, he did not have the slightest taboo to lift the white cloth covering the deceased's body, and carefully examined it, and found no obvious external injuries on the female deceased's body, but only found that the deceased's nose was fractured in the deceased.

After Xu Lang checked it, he stood up, took off his gloves and said: "According to the degree of zombie and corpse spots, the female deceased should have been dead for more than 30 hours, and she should have been covered with something when she was asleep, it should be a pillow or quilt on the train." ”

Hearing Xu Lang's conclusion, Ding Yan nodded, which was the same as his conclusion.

After Xu Lang looked at the corpse, he turned his head and asked Ding Yan, "Have you figured out the identities of the two deceased?" ”

Without waiting for Ding Yan to speak, Deng Zijun hurriedly said: "The man's name is Zhang Kaiji, he is forty-two years old this year, and he is from Chengdong District, S City. ”

"The woman's name is Zhang Huazhi, she is now eight years old Chinese New Year's Eve, and she is from Qiyang City."

"All surnamed Zhang? Could it be that they are related to each other? Xu Lang asked.

It's just that after Xu Lang asked this question, Xu Lang shook his head and felt that it was unlikely, although both of them were surnamed Zhang, but one person was from S City and the other was from Qiyang City, except for being husband and wife, it should not be a direct relative, if it was a relative, it should also be a distant relative or something.

"According to our investigation, Zhang Kaiji and Zhang Huazhi are husband and wife." Deng Zijun said.

Xu Lang nodded, he remembered something, looked at Deng Zijun and asked, "By the way, you said that there is another person named Zhang Haonan, where is he from?" ”

"It's also from Qiyang City."

Xu Lang lowered his head and groaned, Qiyang City is the last station where this train passed through Eyan City, so it seems that Zhang Huazhi, Zhang Kaiji and Zhang Haonan should know each other, so Xu Lang asked: "What is the relationship between this Zhang Haonan and the two deceased?" ”

Deng Zijun and Ding Yan both shook their heads and said, "It's not clear for the time being, but it is estimated that we will know tomorrow." ”

Xu Lang raised his wrist and looked at his watch, it was already more than twelve o'clock in the evening, and it was not early, Xu Lang turned around and glanced at Xiao Yueyue, who was standing next to the corpse, yawning, and said: "Then you can continue to investigate, the biological samples in the fingernails of the male deceased should be sent for testing immediately, if these biological samples are not the deceased himself, then, it is likely that they were left by his murderer." ”

Ding Yan nodded and said, "Okay." ”

"In addition, the relationship between Zhang Kaiji, Zhang Huazhi and Zhang Haonan must be investigated to see if there is some kind of connection between them, which will bring great benefits to you in solving the case."

Ding Yan nodded again.

After Xu Lang said this, he took Xiao Yueyue's hand and walked out of the morgue, and the others also walked out with him.

Xu Lang and the others naturally couldn't go back to the interrogation room, but walked out of the police station, Xu Lang suddenly stopped when he walked out of the police station, turned his head, and said to Ding Yan: "If Zhang Haonan didn't get in the car, you can check the woman who lives in the sleeper and investigate her identity." ”

Ding Yan was stunned for a moment, then nodded.

After saying this, Xu Lang took Xiao Yueyue and got into Ning Yanran's car, and after Lu Xing walked out of the police station, he directly stopped a taxi, and after he got into the taxi, he said to Xu Lang and them: "See you in the bureau tomorrow." ”

————

After Xu Lang and the others left, Ding Yan and Deng Zijun were still standing at the door of the police station, Deng Zijun looked at Ding Yan's extremely excited expression and felt very puzzled, so he asked, "Director Ding, what's wrong with you?" ”

Hearing Deng Zijun's question, Ding Yan slowly turned his head, looked into Deng Zijun's eyes and asked, "Do you know who that man was just now?" ”

Deng Zijun thought that Ding Yan was going to ask something, and after doing it for a long time, it turned out that he was asking this, he pursed his lips and said, "Xu Lang, isn't it written on his ID card?" ”

"Then do you know what Xu Lang's identity is?" Ding Yan asked again, his tone a little excited.

Deng Zijun looked at Ding Yan with a puzzled expression, and said in his heart You are not old, Deputy Director Ning said just now, Xu Lang is the criminal investigation consultant of S City, why did Ding Yan forget it so quickly, so he asked worriedly: "Director Ding, are you okay?" ”

Ding Yan was stunned for a moment, and then glared at Deng Zijun fiercely, and said angrily: "What can I do?" ”

"Then why are you asking me this?" Deng Zijun asked puzzled.

"Xu Lang is not simple." Ding Yan turned his head and looked at Xu Lang and said in the direction they left.

Deng Zijun nodded, talking nonsense in his heart, a deputy captain of the second criminal investigation team and a person personally accompanied by the deputy director of the Public Security Bureau of S City, can it be simple? Although he is a newcomer who has only been working in the police station for a long time, he has no experience, but it doesn't mean that he doesn't understand the world, when he learned the identities of Xu Lang and Lu Xing, he knew that Xu Lang was not simple.

Ding Yan turned his head and looked at Deng Zijun's impatient expression, knowing that Deng Zijun should not have connected the man just now with the man who was famous in S City back then, he didn't want to tell Deng Zijun who Xu Lang was, but when he thought of his attitude towards Xu Lang when he interrogated Xu Lang before, Ding Yan thought about it, and said: "Do you know who the previous captain of the second criminal investigation team was?" ”

Deng Zijun was stunned, he thought for a while and said, "Isn't it Ning Yanran, the current deputy director of the General Public Security Bureau?" ”

"I'm talking about the captain before Ning Yanran." Ding Yan reminded.

Deng Zijun thought for a while and said, "I remember, it seems to be a person named Xu... Xu Lang's person, yes, it's Xu Lang, I heard, this Xu Lang is a very powerful person, the efficiency of solving cases is the highest and fastest person in recent years, when I was studying in the police academy, I often heard teachers talk about him, he is the object of my admiration, Director Ding, why did you remember to mention him? ”

Ding Yan looked at Deng Zijun with strange eyes and said, "What is the name of the object of your worship?" ”

"Xu Lang."

"And what was the name of the man who left just now?"

"Xu Lang."

After Deng Zijun blurted out this name, he immediately thought of something, he suddenly looked at Ding Yan with a shocked and incredulous expression, and said, "Director Ding, the Xu Lang just now shouldn't be the Xu Lang who has been missing for many years, right?" ”

Ding Yan nodded, turned around and walked back to the police station, and said as he walked: "Who else can there be besides him?" ”

"Huh?!"

"How is that possible? Hasn't Xu Lang been missing for years? There was news that he was dead, and when I was at the police academy, I was full of regret when I heard the teacher mention him. Deng Zijun said.

Ding Yan shook his head, and said with a somewhat solemn face: "I never believed that people like Xu Lang would die easily, at the beginning, when I saw his name, I felt a little familiar, but I didn't think about it at the time, and later, when he took out his ID card, I knew who he was, but I didn't expect that after several years, he came back, and it seems that there is a big case in S City." ”

"Why do you say that?" Deng Zijun asked curiously.

Ding Yan said slowly: "Didn't you find out? Who came back with Xu Lang? ”

"Lu Xing, what's wrong?"

"Who is Lu Xing?"

"The deputy captain of the second criminal investigation team."

"What is the second criminal investigation team, you should know in your heart that in addition to having a criminal investigation detachment in the four districts of east, west, south and north in our S City, there are also two criminal investigation teams, one of which is the second criminal investigation team, the second criminal investigation team has been the top criminal investigation team in S City over the years, and all the cases taken over by the second criminal investigation team are big and important cases, difficult cases, which you should know."

"I know all this, but what does this have to do with Xu Lang's return?"

Ding Yan sighed, shook his head, and said: "Lu Xing, as the deputy captain of the second criminal investigation team, is also a soldier under Xu Lang's former subordinates, he personally went to find Xu Lang from that distant place, there must be something difficult to solve in S City, and even the second criminal investigation team can't solve the case, think about it, what kind of case is it?" ”

Hearing Ding Yan say this, Deng Zijun also felt a trace of unusual aura.

Ding Yan continued: "Moreover, Deputy Director Ning personally accompanied Xu Lang today, and it can be seen that the Public Security Bureau attaches great importance to this case. ”

"What the hell is that case?" Deng Zijun asked.

Ding Yan shook his head, he is just the director of a police station, and he doesn't know a lot of things, a big case like this, unless it is completely solved, or the superiors do not have sufficient evidence and clues, it is impossible for them to know, Ding Yan is also wondering in his heart, what happened in S City, so that Xu Lang, a person who has disappeared for more than five years, will reappear? However, no one told him the answers, and he should be thinking not about these questions now, but about how to solve the murder on the train at hand.

Thinking of this, Ding Yan shook his head and didn't think about anything more.

————

On the way back, Ning Yanran drove, Xu Lang sat in the co-pilot, and Xiao Yueyue fell asleep on the chair in the back.

It was already late at night, and there were hardly any people in sight on the bustling and lively streets during the day, and there were not even many vehicles.

The car was driving on the street, Ning Yanran and Xu Lang were silent and did not speak, Xu Lang was thinking about the case on the train, while Ning Yanran was thinking about tomorrow's work arrangement, how to deal with these problems after Xu Lang came back.

The murder on the train, Xu Lang felt a little strange and unbelievable, the woman named Zhang Huazhi should have been killed before Xu Lang and them arrived at the sleeper box, so who would be the person who killed Zhang Huazhi? That young woman, or Zhang Kaiji?

In fact, when Xu Lang and the others went to the box again, Xu Lang noticed Zhang Huazhi's abnormality, but Xu Lang was thinking about other things at that time, and he didn't have the heart to notice these, so he didn't find it, and the most strange thing for Xu Lang was the killing of Zhang Kaiji.

Xu Lang remembered that before he got off the train, he saw that Zhang Kaiji was still alive, although they did not speak and communicate, but Xu Lang was still sure of this, and after the train entered the station at that time, the young woman didn't know where to go, and only Zhang Kaiji and Zhang Huazhi, who had been dead for a long time, were left in the box, so, who killed Zhang Kaiji? Why did you kill Zhang Kaiji? Who is the murderer who killed Zhang Kaiji? Could it be the young woman?

Thinking of the young woman, Xu Lang remembered one thing that Ding Yan mentioned when he was at the police station just now, the passenger in the lower bunk opposite Zhang Kaiji was a man named Zhang Haonan, but this Zhang Haonan did not get into the car, but the woman was in the car, so, where did Zhang Haonan go? Why didn't he get in the car? What is the relationship between that woman and Zhang Haonan? None of this is clear for the time being.

Regarding this murder on the train, Xu Lang has several doubts in his heart.

First, where was Zhang Huazhi killed? Was they killed in Qiyang City, or were they killed during the time when Xu Lang and the others changed from hard seats to sleepers?

Second, who killed Zhang Huazhi? And are the murderer of Zhang Huazhi and the murderer of Zhang Kaiji the same person? If yes, who is that person? If not, then, then who killed Zhang Huazhi? And who killed Zhang Kaiji?

Third, Zhang Kaiji was killed after the train entered the station and the passengers got off one after another, and at that time, it was a time when people came and went, and it was the most unsuitable time to kill people, but the murderer chose to do it at that time, why did the murderer take such a risk?

Fourth, who was the young woman they saw? What is the relationship between her and Zhang Haonan? Where is she now?

Xu Lang doesn't know these questions for the time being, and the railway station police station is not clear now, everything needs to be investigated to know, and Ning Yanran has no energy to take care of this case for the time being because she wants to investigate the truth of Lu Ye's death, for the time being, the case will definitely be investigated by the police comrades of the railway station police station, today, Xu Lang found a biological sample in Zhang Kaiji's fingernails, as long as it is sent to the technical department for laboratory comparison, the comparison results are out, based on the information of the fingerprint and DNA database of Huaxia Kingdom, The other party's information should come out soon, and catching the murderer is just around the corner.

Thinking of this, Xu Lang didn't think much about these things.

In this way, in silence, the car entered the community, after Xu Lang got out of the car, he opened the rear door and hugged the sleeping Xiao Yueyue from the car, while Ning Yanran followed Xu Lang upstairs after parking the car.

When he arrived at the door of the house, Xu Lang couldn't open the door because he was holding Xiao Yueyue, so Ning Yanran helped open the door.

After entering the house, Xu Lang first put Xiao Yueyue on the bed in the bedroom, covered her with a quilt, and then walked out of the second bedroom and came to the living room.

Ning Yanran didn't leave, she just sat in the living room, made two cups of tea, and drank it with a cup of tea.

After Xu Lang walked to the sofa and sat down, after picking up another cup of tea and taking a sip, he put down the teacup, he looked at Ning Yanran and asked, "Let the people from the police station investigate this case now?" ”

Ning Yanran thought for a while and said, "Tomorrow, I will let someone from the Chengdong Criminal Investigation Detachment take over this case." ”

Xu Lang nodded, the railway station is in the eastern district of the city, and the Chengdong Criminal Investigation Detachment will take over the case, there should be no problem, thinking of this, Xu Lang didn't think about the murder on the train, but looked at Ning Yanran and asked, "How is the investigation of Lu Ye's case?" ”

Ning Yanran frowned, shook her head, and said, "Everything is still under investigation, but the progress is slow, and there is no breakthrough." ”

Xu Lang subconsciously frowned, he didn't say anything before he knew the specific situation.

After the two of them were silent for a while, Ning Yanran raised her head, looked at Xu Lang and asked, "When are you coming to the Public Security Bureau?" ”

Xu Lang looked around and said: "It is estimated that it will take a few days before I come back, a lot of things have to be cleaned up, and now it is time to start school, Xiao Yueyue has reached the age of going to school, I have to handle the matter of going to school for her, it is estimated that it will take a few days to deal with all these things." ”

Ning Yanran nodded, knowing that what Xu Lang said was right, but she still said, "I hope you can come back as soon as possible." ”

Xu Lang nodded and didn't say anything, and after Ning Yanran finished saying this, she also put down the teacup and left Xu Lang's house.
