When Ning Yanran was talking to Ruan Fanghua, Xu Lang had been observing Tan Wenrui, the silent young man who was standing beside Ruan Fanghua.

Xu Lang found that Tan Wenrui was very sad, his eyes were wooden, his expression was sad, and he seemed to still refuse to believe everything he knew, which made Xu Lang, who had always been suspicious of Tan Wenrui, gradually relaxed, and breathed a sigh of relief in his heart, and said secretly: "Fortunately, it's not him." ”

Criminal investigation is a very boring and cruel thing, boring because when solving every case, especially in the early ice-breaking stage, criminal police often have to do a lot of things and investigate a lot of things, and these things are often not used when the case is solved, but they have to do it, as for criminal investigation is a very cruel thing, it is because, in many criminal cases, unless it is the kind of psychological extreme perversion and distortion, with a strong anti-social-, In addition to the perverted homicidal maniac of anti-human-human character, in fact, the murderers of many criminal cases, they are not really like murder, or rather, they kill just for a very inconspicuous and ordinary thing in the eyes of outsiders, and when the case is solved, people will sigh and sigh after learning the truth, and some cannot accept the truth, however, the truth is the truth, no matter how cruel it is, how outrageous, how incredible, the truth is always just the truth.

Man is a very complex and advanced animal, never underestimate the human mind, but also do not overestimate a person's humanity too much.

After Ning Yanran and Ruan Fanghua had a brief conversation, they sat down, and then Ning Yanran sat opposite them, took a notepad from the table, opened the notepad, picked up a pen, looked at Ruan Fanghua and Tan Wenrui, and said, "We called you to the team, mainly there are a few questions to ask you." ”

Ruan Fanghua saw Ning Yanran asking in this tone, she immediately frowned, and said with some dissatisfaction: "Captain Ning, what do you mean by this?" Are you suspicious of Wen Rui's child? Are you mistaken, it was his family who was killed, and it was his closest people who were killed. ”

Ning Yanran had already expected Ruan Fanghua's attitude, after all, if she had changed to Tan Wenrui, the family would have suffered this kind of change, and it would be too late to be sad, and now that she is suspected, anyone will be angry and angry, and Ruan Fanghua, as Tan Wenrui's teacher, will naturally strongly oppose it.

"Teacher Ruan, you misunderstood, we are not suspecting Tan Wenrui, it's just that Professor Tan Boheng's family was killed, Tan Wenrui is the only survivor, we still have a lot of questions to ask clearly, which will be of great help to us to solve the case, I think, Mr. Ruan, you also hope that our police can catch the murderer as soon as possible and give Professor Tan Boheng's family an explanation, right?" Ning Yanran faced Ruan Fanghua's questioning, and she said in a tone that was neither humble nor arrogant.

Hearing Ning Yanran move out of the name of Professor Tan Boheng, Rao is Ruan Fanghua, who is already in her forties, and it is not easy to say anything, Ruan Fanghua is a teacher, and Tan Boheng's family are all teachers, and Ruan Fanghua was once one of Tan Boheng's students, she was also very angry about the tragic death of her teacher's family, in addition, Ruan Fanghua is already in her forties after all, although she has been teaching in school, it does not mean that she does not understand human relations, she knows that Ning Yanran is right, so, she nodded and said, "What do you want to know, Just ask. ”

"Tan Wenrui." Ning Yanran shouted.

Tan Wenrui heard someone call his name, he subconsciously raised his head and looked at Ning Yanran with a blank expression.

"Where are you from seven to ten o'clock this morning?" Ning Yanran asked.

"He's at school, preparing for the game." Tan Wenrui hadn't spoken yet, and Ruan Fanghua, who was sitting on the side, spoke for Tan Wenrui.

Ning Yanran glanced at Ruan Fanghua, then turned her head and continued to look at Tan Wenrui and asked, "Is that so?" ”

Tan Wenrui may be a little nervous when he saw Ning Yanran wearing a police uniform because he was still young, he didn't dare to look at Ning Yanran, and when he heard Ning Yanran ask, he lowered his head, nodded slightly, and did not speak.

"It's Sunday, and you're just a sophomore in high school, and you're on weekend break, why don't you go home?" Ning Yanran asked.

"Our school is about to hold a math competition recently, and Tan Wenrui is very good at math and is the main force of this competition, so he stayed in school." Ruan Fanghua spoke again.

Ning Yanran asked twice, but Ruan Fanghua rushed to answer, Ning Yanran's good-looking willow eyebrows wrinkled subconsciously, she complained a little in her heart Li Lei, why did she let Ruan Fanghua come over, but after all, Tan Wenrui is the victim's family and the only survivor of this case, Ning Yanran didn't say much, she still looked at Tan Wenrui and asked, "Is that so?" ”

Tan Wenrui nodded again and did not speak.

"Do you have any enemies in your family?" Ning Yanran asked.

"How is this possible? Mr. Tan's family are all good people, how can there be any enemies? Captain Ning, are you mistaken? After Ruan Fanghua asked Ning Yanran this question, she immediately stood up from her seat like a cat with her tail stepped on, and looked at Ning Yanran with an incredulous expression.

Rao is Ning Yanran, who has a good temper, has been disturbed and questioned several times, and her mood is not very good, so Ning Yanran's face gradually became gloomy, and she looked at Ruan Fanghua without speaking.

Ruan Fanghua was looked at by Ning Yanran like this, she didn't seem to notice what was wrong with what she said, she looked at Ning Yanran puzzled and asked, "Captain Ning, what's wrong?" Is there anything wrong with what I said? ”

Just when Ning Yanran was hesitating how to reply to Ruan Fanghua, Xu Lang, who had been standing beside the three of them, leaning on the table, looked at Tan Wenrui and suddenly asked, "Tan Wenrui, how old are you this year?" ”

As soon as Xu Lang spoke, the three people present looked at Xu Lang at the same time, Ruan Fanghua's eyes were full of doubts and puzzles when she looked at Xu Lang, she saw that Xu Lang was not wearing a police uniform, and she didn't know what position Xu Lang was, and Tan Wenrui was frightened by Xu Lang's sudden words, he raised his head suddenly, looked at Xu Lang in confusion, and didn't know how to answer this question for a while.

"He's nineteen years old." Ruan Fanghua said.

Compared with Ning Yanran's politeness, Xu Lang didn't look at Ruan Fanghua, he kept staring at Tan Wenrui's eyes and asked, "How old are you this year?" ”

Maybe Xu Lang's eyes are too sharp and can pierce people's hearts, maybe the momentum on Xu Lang's body is too strong, Tan Wenrui was looked at by Xu Lang like this, and he said for the first time: "Nineteen years old." ”

Tan Wenrui's voice was not loud, a little weak, it didn't sound like a boy's voice, but like a girl talking, Xu Lang and Ning Yanran were stunned after hearing Tan Wenrui's voice.

The expression on Xu Lang's face flashed, he quickly collected his emotions and continued: "Since you have reached the age of eighteen, then, you are an adult, since you are an adult, you should know that you are a person with complete autonomy, no longer a child, I hope that in the next question, you can tell the truth and answer by yourself, okay?!" ”

After Xu Lang finished saying this, he turned his head slightly, glanced at Ruan Fanghua with deep meaning, and then continued to look at Tan Wenrui's eyes.

Tan Wenrui nodded subconsciously under the gaze of Xu Lang's eyes, "Okay." ”

Ruan Fanghua finally couldn't stand it anymore at this time, she stood up abruptly and said to Xu Lang: "This gentleman, are you a policeman?" ”

Xu Lang seemed to have just seen Ruan Fanghua, he glanced at Ruan Fanghua lightly, and said, "My name is Xu Lang, and I am not a policeman." ”

"Since you're not a police officer, what qualifications do you have to ask these questions?" Ruan Fanghua immediately retorted.

"You say qualifications, right? I wonder if this thing qualifies? ”

After Xu Lang said this, he took out his criminal investigation consultant's certificate from his pocket and handed it to Ruan Fanghua.

When Ruan Fanghua took the certificate and looked at it, Xu Lang didn't pay attention to her anymore, but looked at Tan Wenrui and asked, "It's still that question, you are from seven to ten o'clock this morning, where are you during this time?" ”

"At school."

"Where is it at school? With whom? And who can prove it to you? ”

"I'm in the dorm, and my roommate can prove it for me."

"Your roommate? What's his name? Why didn't he come home on weekends? ”

"His name is Li Jun, and his family is not a local, unless it is winter and summer vacations, he rarely goes back."

Hearing Tan Wenrui say this, Xu Lang paused slightly, and then continued to ask: "Just now your homeroom teacher said that you are going to participate in a math competition recently, right?" ”

"Yes."

"How many people are in your class?"

"Three."

"Who else but you?"

"Cheng Mei, a member of the study committee, and Wang Gang, the representative of the mathematics class."

"Do they stay in school too?"

"It should be there." Tan Wenrui hesitated and said.

"Should it be? Is it in or not? Xu Lang asked.

Tan Wenrui thought for a while and said: "Cheng Mei is at school, I saw her when I left the school with our head teacher, as for Wang Gang's absence, I don't know." ”

Hearing this, Xu Lang didn't continue to ask for the time being.

Ruan Fanghua had already finished reading Xu Lang's documents, although she didn't know what the position of the criminal investigation consultant was, but she was not a fool, seeing that Ning Yanran, the captain of the second criminal investigation team, neither stopped nor interrupted his questioning after Xu Lang opened his mouth to ask, but instead took a pen and recorded the questioning there, she knew that Xu Lang's position must be bigger than Ning Yanran, so when Xu Lang asked, she didn't interject, and now, hearing Xu Lang keep asking Tan Wenrui if he had an alibi at the time of the crime, This made Ruan Fanghua's psychology very uncomfortable, she secretly thought, Professor Tan Boheng's family was killed, your police don't go to investigate the scene, don't go to track down the murderer, why do you want to arrest the victim's family and ask so much here, and when Xu Lang finally stopped asking, she said: "Consultant Xu, now it's the case of Wen Rui's family being killed, the questions you asked don't seem to have anything to do with the case, right?" ”

Xu Lang didn't look back at her, but looked at Tan Wenrui and asked, "Do you have any enemies in your family?" ”

Tan Wenrui frowned, thought about it in silence for a long time, shook his head, and said, "There should be no enemies." ”

"Are you sure?" Xu Lang continued to ask.

Tan Wenrui did not hesitate this time, and said directly: "My grandparents and my parents are all teachers, they don't know many people except for teaching in school, except for their students, they are the parents of students, my family is very good, and they never make enemies with others." ”

"No, or don't you know?" Xu Lang subconsciously squinted his eyes and asked.

Tan Wenrui didn't speak this time, but looked at Xu Lang with puzzled eyes, he didn't understand why Xu Lang asked like this.

After Xu Lang saw Tan Wenrui's puzzled eyes, he hesitated for a moment, but still said: "We just came back from your house, your grandfather and your father were poisoned, your grandmother was killed by someone who pierced her chest with a knife, your seven-year-old sister was strangled to death with a pillow, and your mother was killed in the kitchen, your mother's right hand was trampled and broken, her hair was forcibly pulled down, and on your mother's back, there are traces of being trampled on, if it wasn't for the enemy, I can't think of anyone else doing anything so crazy for a while. ”

After Xu Lang finished speaking, he stared into Tan Wenrui's eyes and looked at the young man in front of him who looked a little immature.

After Tan Wenrui listened to Xu Lang's words, his already red eyes suddenly turned even redder, tears swirled in his eyes, and in the end, he slid down his cheeks silently, he bit his lip tightly, raised his head, and looked at Xu Lang's eyes, as if he wanted to determine whether what Xu Lang said was true.

"I just came back from the scene, I've seen all the bodies of your family, I won't lie to you." Xu Lang explained.

Hearing Xu Lang say this, Tan Wenrui finally lowered his head, raised his hand to wipe the tears on his cheeks, and said in a choked voice: "In my impression, my grandparents and parents are teachers who work hard for their students, although they are a little strict when teaching, they are still very kind on weekdays, since I can remember, I haven't seen my family and anyone blushing, I really don't know who will have a grudge against our family, what is the deep hatred and hatred, to kill my family so cruelly?" Who is it? Who is it?! Woowoo"

In the end, this young man, who had never believed that the bad news was true since he learned that his family had been killed, finally began to cry like a helpless child after Xu Lang told the truth.

As Tan Wenrui's grief-stricken crying voice sounded in the office area of the second criminal investigation team, Tan Wenrui's head teacher, Ruan Fanghua, immediately turned around and began to comfort Tan Wenrui, holding the child who had lost all his relatives at once in his arms, gently patting his back with his hand, and comforting him in a low voice, Ning Yanran also put down the pen in her hand at this time, raised her head, looked at Tan Wenrui, who was crying, and turned her head again, looking at Xu Lang, who was expressionless, her good-looking willow eyebrows wrinkled again, She somewhat disagreed with Xu Lang asking Tan Wenrui so much, after all, he was still a child.

Ning Yanran stretched out her hand and pulled Xu Lang's sleeve, Xu Lang turned his head and looked at Ning Yanran with inquiring eyes.

"Why don't you let them go back first? After all"

Without waiting for Ning Yanran to finish speaking, Xu Lang shook his head resolutely and said: "Life and death are common things for people, he has to experience it sooner or later, and he is already eighteen years old, he is an adult, and he is still a boy, I believe that children who grow up in that kind of scholarly environment are not so fragile, I believe in him, wait." ”

Hearing Xu Lang say this, Ning Yanran couldn't refute anything, she knew that Xu Lang was right, and she knew that if she wanted to solve the case as soon as possible, Tan Wenrui was the only survivor of the Tan family and a key person, he must know a lot about the Tan family, if you can get some useful clues from him, then it is a good thing to solve the case, just

Thinking of this, Ning Yanran raised her neck, looked at Xu Lang who was expressionless, and looked coldly at Tan Wenrui who was crying in Ruan Fanghua's arms, Ning Yanran's eyes were a little complicated and confused, she felt that since the Bu Zimo case, Xu Lang had changed a lot, before, when she and Xu Lang handled the case together, although Xu Lang didn't talk much on weekdays, but whenever there was some tragedy, Xu Lang's face would show a look of compassion and sympathy, however, at this moment, Xu Lang was like an emotionless person, Looking at all this coldly, this made Ning Yanran feel that Xu Lang in front of her was a little unfamiliar.

After about ten minutes, Tan Wenrui finally stopped crying under Ruan Fanghua's comfort, he had already sat up straight from Ruan Fanghua's arms, wiped his tears with the back of his hand, looked at Xu Lang with red eyes, and said: "If you still want to ask, just ask, I will tell you everything I know, but I have one condition." ”

"On what terms?" Xu Lang asked.

"If we catch the murderer of my family as soon as possible, we must bring him to justice and cut him with a thousand knives." Tan Wenrui gritted his teeth and said.

Xu Lang pondered for a moment, then nodded and said: "Don't worry, even if you don't say it, we will do it, after all, it is the duty of our police to arrest the murderer, what you have to do now is to answer our questions and provide us with some useful clues as much as possible, only in this way can we bring the murderer to justice as soon as possible." ”

Tan Wenrui nodded with a very serious expression and said, "Okay, I know, you can ask." ”

Xu Lang saw Tan Wenrui like this, and there was an appreciative look in his eyes, he felt that Tan Wenrui was a very good child, at least much better than him back then.
