I don't want to solve the case when I'm a little policeman.

Chapter 707: Special method, practicing martial arts in the snow
Testing the DNA of Ni Xin and Li Danning's son would lead to suspicion that this child is not Ni Huaiyi's son, but his grandson.

Seeing that everyone was stunned by his words, Xu Zheng quickly added: "Among the dominant genetic characteristics, the grandson has a certain chance of inheriting the dominant characteristics of his grandfather.

Before, we all thought that Li Danning and Ni Huaiyi were often together, and the forbidden love between teachers and students was a big gimmick.

There is also a child who looks like Ni Huaiyi.

So we immediately determined that the child was Ni Huaiyi's.

But what happened tonight, you also saw, for Li Danning, He Rujun was not only a lawyer who helped her in the lawsuit, but also a trump card for her, but she actually used this trump card to kill Ni Xin.

Therefore, let’s check the relationship between the child and Ni Xin. "

Liu Linlin was knocked unconscious by this big melon. She looked suspicious, "Didn't Ni Xin live abroad five years ago? Could it be that he returned to China?"

Zhang Kaiwen stood up for Xu Zheng this time, "Isn't it normal for Ni Xin to return to China? I just checked the information of Li Danning's son. He was born in November 2031.

According to the ten-month pregnancy period, Li Danning should have been pregnant during the Chinese New Year.

Ni Xin was studying abroad at that time, but this did not prevent him from going home for a few days during the New Year.

How about we contact the immigration detachment to check his entry and exit records over the years? "

Captain Xie waved his hand and made a decision with a rough face, "It's so troublesome to directly check the DNA of the child, Ni Xin and Ni Huaiyi. In extraordinary times, extraordinary means are used.

There is no need to go through the application process, otherwise.”

He didn't say the rest, but everyone knew that it was a bit embarrassing to apply to the relevant leaders of the municipal bureau to test the DNA of Ni Huaiyi and his children. Some leaders might not agree to it out of favor.

Detachment Yang thought about it for a while, "What we need now is the child's DNA sample and Ni Xin's. As for Ni Huaiyi, we don't want to test it for the time being."

"I have the child!" Xu Zheng said suddenly. After saying this, he realized that something was wrong. How could he have it?

He quickly explained, "It's like this. Didn't I lead the team to the airport police station a few days ago and brought back Li Danning? Her son is very cute. I touched his little head and stroked a hair out of habit.

It's still in my briefcase, luckily I didn't lose it. "

Xiao Xiaoran, who had been sitting aside as a spectator, became interested, "Xu Zheng, what kind of habit do you have? Could it be that you just smoothed a piece of my hair?"

Liu Linlin was also making noises from the side, "What kind of habit is he doing? I think it's a quirk. Xu Zheng, did you get it from working on anti-trafficking cases?"

Xu Zheng rummaged through his briefcase and found the evidence bag containing Li Danning's son's hair, and replied to the question with a smile, "It's true, because the first thing the anti-trafficking office needs to do is collect the DNA of the abducted child.

Besides, to be sure whether the child is Ni Huaiyi's, we still need to rely on DNA testing.

It’s just that when I saw the child for the first time, I only thought that the child belonged to Ni Huaiyi, and I really didn’t think about Ni Xin. "

Xiao Xiaoran shook her head, with various feelings in her heart. Originally, she had thought of waiting for Xu Zheng to finish his postgraduate studies in forensic medicine with Ji Qianli and then study for her doctorate, but now, she seemed to think that Xu Zheng didn't need to study psychology.

If this kid doesn't learn psychology, he always takes precautions in everything he does. If he learns it again, no one will be able to trick him.

It's just that Academician Xiao, a top figure in the psychology industry, didn't see through Xu Zheng's true level at this time, otherwise, she wouldn't think so.

When teachers choose students, sometimes they can achieve mutual success.

Zhang Kaiwen smiled and said, "You are such an old man. You never forget to dig holes wherever you go. Have you always regarded Ni Huaiyi as a suspect?"

Xu Zheng glanced at him and was too lazy to answer him. Regarding Ni Huaiyi's matters, you can do it but not say it. If you say it, it will be a bit unkind.

After all, he has also been a police consultant for the Magic City Bureau for more than ten years.

At this time, Jiang Wentao suggested, "It's easy to handle Ni Xin's side. Shouldn't we ask the Xincun Police Station to send people to monitor and protect him? Wouldn't it be good for our colleagues there to find a sample of his DNA?"

Wouldn't it be enough to just send it over then? "

Team Xie nodded, "This suggestion is feasible. Without further ado, Xiao Jiang, please go there yourself. The road is slippery at night. Bring a colleague with you. Don't worry. Safety is the priority."

After Jiang Wentao led the people to leave, Detachment Yang looked at his watch and said, "I'll call the old man in the laboratory department and ask him to come over and work overtime. Xiao Jiang has to go back and forth for more than an hour, and he still has to do tests."

If everyone is tired, sleepy or hungry, you can go relieve yourself first.

Xiao Xu, please entertain Academician Xiao well. "

In fact, there won't be too many people guarding here in the future, but now Li Danning still needs people to observe 24 hours a day, and Ni Huaiyi also needs people to take turns monitoring.

Besides, how is it possible for you to go home and rest while others are busy?

Also, if the case is solved tonight, it will be all credit, so some people are still here even if they are tired.

Xiao Xiaoran naturally didn't need these credits. After taking a look at Li Danning opposite the camera, she asked Xu Zheng to find a small reception room for her to rest.

After Xu Zheng brought water and blankets to the teacher he had just recognized, Xiao Xiaoran smiled and ordered, "Stop working and sit down first. I want to talk to you first while I have time.

Ji Qianli and I are old friends, and I learned a lot about you through him.

I also know that you are studying psychology on your own. Now I want to ask you, what aspect do you want to learn with me? "

Xu Zheng did not hesitate and confessed his thoughts directly, "Applied psychology, criminal psychology and social psychology."

There are many categories of psychology, and the three categories he mentioned are all related to his current work. Academician Xiao was not surprised and just nodded, "I see you are currently studying at Lao Ji's postgraduate school.

You can graduate in one year, right?
Why don't you apply directly for my PhD program after you get your degree? "

Xu Zheng asked: "Teacher, what do you mean, do I still have to take the exam?"

"Otherwise?" Xiao Xiaoran sneered, "What, you think my doctoral students will be admitted without taking the exam? If you don't pass the exam, it can only mean that we teachers and students have no chance."

He knew that good things are not free, but Xu Zheng was not discouraged and smiled confidently, "It's just a test. Don't worry, teacher. I'm definitely fine. I just don't know if you set the questions for the test?"

"Go out and close the door." Xiao Xiaoran pointed to the door. At this moment, she finally figured out Xu Zheng's character and was too lazy to talk to the naughty student she had just accepted.

"When school starts in a few days, you can take the time to come to the capital and let's talk in detail."

Xu Zheng nodded quickly. Seeing that the teacher was indeed in low spirits, he hurriedly withdrew, "Teacher, please take a rest first. I'll keep an eye on Li Danning."

After leaving the small conference room, Xu Zheng also yawned. He also felt a little tired from running around for the past two days, but what bothered him more was that he had not found a good way to interrogate Li Danning and Ni Huaiyi.

He first went to the office where the temporary task force specialized in monitoring Li Danning, and found that two colleagues were already staring at the screen. He did not disturb them and left again.

Back at the big meeting, colleagues who had no tasks had fallen asleep on the table.

He went to the small conference room where He Rujun was and found that she was sitting there in a daze. Ji Meiyue next to her had already fallen asleep.

After closing the door, he retreated to the corridor. The place that was quite lively just now suddenly became deserted. This sharp contrast almost made him unable to adapt.

But it's still late at night, so let's find a place to study the case first.

Xu Zheng moved the files and started looking at the suicide case at Sheshenya in Emei Mountain ten years ago. This was the first case of the entire hypnotic suicide case.

There is currently no substantive evidence against Li Danning, but she can also be identified as the murderer in this case. But is she the only murderer? Did Ni Huaiyi take action?

There are no answers to these questions yet.

The motive is the initial cause of every case, but not every case can reveal the murderer's motive. For example, in the case of Sheshenya, was Li Danning seeking revenge on the four dead people, or was it to verify her hypnosis skills.

Xu Zheng couldn't judge.

Detachment Yang and Brigade Xie, as well as experts in criminal psychology, were unable to judge.

This is mainly because Li Danning is proficient in psychology, and the police have too little evidence to infer her from what has happened.

In other words, Li Danning is different from normal people, and she is most likely suffering from severe mental illness.

This situation often happens among psychiatrists, whose probability of suffering from mental illness is much higher than that of ordinary people.

Therefore, if Li Danning really has a mental illness, or a mental illness, then thinking about her criminal motives is a bit different.

"Alas, it seems we have to find another way!"

After reading the files for a long time, Xu Zheng was a little discouraged when he got such a result. After thinking about it, he still had to continue to improve the previous plan.

However, providing false news to Li Danning was suspected of eliciting a confession. Although no one mentioned this issue just now, it existed objectively. As he was thinking about it, he suddenly wanted to go out for a walk.

He put on his coat and took the elevator downstairs. The cold wind was still there, snowflakes were flying, and the biting cold air hit his cuffs.

Nowadays, Xu Zheng can be regarded as a martial arts practitioner. The cold is nothing. He even thought that it would be extremely refreshing to have a long sword or even a stick to dance in the wind and snow.

It's a pity that this is the Magic City Bureau. Even if there are not many people on duty during the Spring Festival, it is not a place where he can be messed with casually.

"What are you doing here, Xiao Xu? Do you want to learn some boxing skills in this heavy snow?"

I don't know when Detachment Yang came over. He reached out to catch the falling snowflakes from the sky, "I saw you standing here alone upstairs. It happened that I couldn't sleep, so I came down for a walk."

"You don't have much to wear, so don't catch a cold." Xu Zheng asked with concern.

Unexpectedly, detachment Yang burst out laughing, got up on his horse and started to perform a set of Bagua boxing, which included collapse, pick-up, hug and split. His boxing skills were yin and yang, strong and soft in movement and stillness.

Dodging left and right, jumping up and down, punching down and retracting his legs, a black and white Bagua diagram formed under his feet. "Okay, okay!" Xu Zheng clapped and laughed. When you meet a confidant, you should pour a pot of wine. "Hardness comes first, then softness hides. Softness comes first, then hardness comes out... Yang Detachment, you must have 30 years of practice in this boxing technique." Alright?"

Detachment Yang looked at the Bagua diagram at his feet and smiled with pride. Fortunately, he didn't make a fool of himself. "It's embarrassing, it's embarrassing. I started learning this boxing technique since I was a child. I feel ashamed to say it."

I am originally a descendant of the Yang Family Tai Chi, a descendant of Yang Luchan in the late Qing Dynasty, but since I was a child, I have loved practicing Bagua Quan, which was passed down from Dong Haichuan.

I have persisted for more than 30 years, and now I can see some success. "

Xu Zheng was filled with envy. This was more than just a small achievement. Just looking at the Bagua picture at his feet, he would definitely not be able to fight without his understanding and boxing skills. "Detachment Yang, I would like to ask, have you ever had blood on your hands?" "

"Of course, but I can't say how much." Detachment Yang said with emotion, "In our line of work, there is no one who is a front-line veteran criminal investigator who doesn't have blood on his hands."

"That's right." Good boxing skills and force are fed by human life. If you practice boxing for a lifetime without killing anyone, you won't be able to practice the true meaning of boxing. After all, the ancients created martial arts to kill people.

As Xu Zheng talked, he walked twice around the Bagua diagram at his feet, as if gold had been dropped on the ground.

Detachment Yang naturally saw what he was thinking. Unfortunately, Xu Zheng was already in his 20s and was past the age to learn Neijiaquan. "Do you want to learn my boxing style? You are still coy and not a martial artist."

I don’t have any sectarian or sectarian views.

According to what people in the martial arts community said in the past, we both belong to the public sect. If you ask me to teach you martial arts, you are competing with each other in the same sect. Can I still agree? "

Xu Zheng was overjoyed. He had been interested in Neijiaquan for a long time, but he had never been able to find a good teacher. As for the boxing techniques on the market, they were all deleted and deleted.

The most important thing is that there is no corresponding breathing method.

It was quiet in the dead of night, the snow fell silently, and only the north wind whistled between the sky and the earth, like a wolf howling or a tiger roaring.

The two of them walked to a secluded area of ​​the city bureau courtyard while discussing their respective boxing techniques and the inheritance of Bagua Boxing.

Only today did Xu Zheng learn the real name of Team Yang, Yang Yance, 41 years old, from a martial arts family in northern Hebei, who mainly inherits Yang Luchan's Tai Chi and Dong Haichuan's Baguazhang.

When they walked to a secluded place, the two of them got excited talking and made some random moves, but they didn't actually fight. After all, they were both very powerful in combat.

Detachment Yang shook his arm, "Xiao Xu, I may not be able to beat you if you really hit me. You react too quickly, and your punches are heavy and fast. I really don't know how you practice. You just relied on foreign martial arts to do it." Among the great masters.”

Xu Zheng secretly felt ashamed. These were master-level fighting skills given by the system, and his body had been modified by the system. In fact, he did not learn any boxing skills, and his lethality was no worse than other martial arts students.

Especially in terms of capturing, he should be unbeatable.

After all, he is probably the only person in the world who has a system.

Xu Zheng said modestly: "You are still very good. Baguaquan does not mean palms, fists, elbows and wrists, shoulders, waist, hips, knees and feet, hands, eyes, body, and steps. They are all martial arts moves.

Mine is pure brute force, unlike you, who learned internal martial arts.

Team Yang, do you have to start from the basics to learn Neijiaquan and practice the corresponding breathing techniques? "

Detachment Yang nodded, "That's true, but Xiao Xu, you have never practiced Neijiaquan, but I heard that your breathing is even and continuous, and even your snoring has the sound of thunder.

Have you also learned breathing techniques? "

Xu Zheng did not hide anything and directly explained the six-character mantra breathing method given by the system to Detachment Yang.

"Okay, okay!" Detachment Yang clapped his hands and laughed, and said as an expert, "Xiao Xu, your breathing method is not simple. It is even more precise than the dozen or so methods passed down by our family. It is really a rare good thing. "

How can the products produced by the system be rubbish? Xu Zheng also smiled and said: "A sword is given to a hero. You taught me Bagua Quan, how could I hide it?"

"Haha." Detachment Yang looked very happy this time, his glasses almost fell off with laughter, "Come on, let me teach you some footwork and stances, as well as breathing techniques for boxing movements."

As the saying goes, when practicing boxing, you must first practice stances. With the rise of Yang's detachment teacher, Xu Zheng learned quickly.

The two hid here and practiced for more than an hour. They didn't go back until Team Xie couldn't find anyone to call them.

"What are you two doing? Your hair is wet, your clothes are wet, your face is sweating, and your whole body is steaming. Did you go for a run?"

Xu Zheng and Detachment Yang looked at each other and both laughed. But after a while, Ji Meiyue came out and saw the situation of the two of them. She quickly came over to urge them, "Detachment Yang, Xiao Zheng, it's snowing heavily outside.

You two are still our backbone in handling cases. What if you catch a cold? "

With that said, she pulled Xu Zheng into the small conference room, prepared hot water for him, and wiped his hair.

Detachment Yang smiled, turned around and went back to the office with Team Xie to change clothes, "We went out to practice martial arts. Xiao Xu, a young man, is really talented. He mastered the Bagua boxing technique in an hour.

Given time, I estimate that he will definitely surpass me in Bagua Quan within three years. "

Team Xie, a 1.8-meter-[-]-meter tall man who also has some kung fu skills, looked sour when he heard this, "I have asked for your boxing skills several times, but you insist that I am too old and missed the time.

Why are you so open today? "

Detachment Yang was very happy today. He pretended to stare when he heard this, "Come here, I will teach you a breathing method that is more subtle than Bagua Quan."

Captain Xie stopped us, "We'll talk about this later. There's good news now. The DNA test results are out. Whose son do you think Li Danning's child is?"

Detachment Yang was changing clothes and wiping his hair, "It doesn't really belong to Ni Xin, does it?"

"Hey! It's true!" Brigade Xie took out the DNA test certificate, turned to the last page, and showed Detachment Yang, "Fortunately, Xiao Xu thought of this, otherwise, we really wouldn't have discovered this situation.

Maybe it doesn't matter to Li Danning if the news spreads.

But for Ni Huaiyi, it is definitely a very bad thing.

Because his son is about to get married.

By the way, do you know which family his future daughter-in-law is from? "

Detachment Yang scoffed, "She's still mysterious, isn't she the daughter of a certain leader from the government? If we find out, he will have to thank us."

Captain Xie waved his hand and did not care about the leader's thanks, "I think we can give the interrogation method that Xu Zheng proposed before to stimulate Li Danning a try.

Just imagine, she was Ni Huaiyi's student in name, and she stayed with him all day and night, staying in the teahouse for half a day, but the child she gave birth to was Ni Xin's.

Do you think the relationship between them is that father and son share the same fate, or is there a third party involved?
Or maybe Li Danning and Ni Huaiyi just had a pure teacher-student relationship, but it was Ni Xin who broke her up five years ago? "

Detachment Yang shook his head and made a suggestion, "You are all guessing, there is no evidence to support it. As for the relationship between them, I think we can start with Ni Xin, what do you think?"

This time it was Captain Xie's turn to shake his head, "Ni Xin is about 30 years old, but has a rich resume and has seen a lot of things in the world.

If we ask Li Danning that his child is his, he probably won't tell the true relationship between his father and Li Danning.

Li Danning didn't accuse him of coercion, and he didn't break the law. I think he kept silent when he came to the police station. "

Detachment Yang scratched his still wet hair, "What do you think we should do? Should we just have a showdown with Li Danning?"

Captain Xie walked around twice with his hands behind his back, "I don't have any good suggestions. Forget it, let's leave this matter to Xu Zheng. Young people have quick minds and may be better able to handle Li Danning."

At this time, Xu Zheng was still being nagged by Ji Meiyue, "Are you going to practice martial arts in the heavy snow in the middle of the night? How can anyone practice martial arts at night? Are you crazy?"

Xu Zheng let her chatter while rubbing his hair, and stopped explaining. The woman had no idea how interesting martial arts training was, so he changed the subject.

"Sister Meiyue, does Team Xie have any latest news from us?"

"Well, Jiang Wentao brought back Ni Xin's toothbrush, and the laboratory department extracted his DNA. It is indeed a father-son relationship with Li Danning's son." Ji Meiyue glanced at He Rujun who was sitting aside.

She was not worried that Lawyer He would leak the news.

Then he asked Xu Zheng, "How are you going to use this news next?"

"There are three ways. One is to ask Ni Xin to see if we can get the relationship between them through him;

Article [-]: Interrogate Ni Huaiyi, but there is little hope, or it is basically impossible to obtain a useful confession;

The third one is to interrogate Li Danning directly. I still think we can stimulate her more.

At present, the conditions that can be stimulated include the identity of the child's biological father, Lawyer He's mission failure, Ni Xin's death, and we have cracked the people she hypnotized, including her patients in Xiangdao, including Lawyer He.

These are the conditions that stimulate her anger. "

After Xu Zheng finished speaking, he thought for a moment and added: "There is also evidence we currently have, such as the contents of Chi Jian's voice recorder being played to her in turn.

I don't believe she wasn't ashamed when she heard Chi Jian's voice. "

"She is really not necessarily ashamed!" He Rujun sighed and fell into memories, "We actually don't go to the same school, but we have known each other since we were in college.

I still know Li Danning relatively well.

She is quite self-centered and, to put it harshly, self-interested. She probably won't regret what she has done.

If you want to anger her, I think what Officer Xu just said is not enough. "

Ji Meiyue put away the towel for Xu Zhengcuo's hair and asked curiously, "That's right, Lawyer He, you are a good friend of Li Danning and you should know her very well.

What do you think should be done to make her angry, the kind that makes her particularly angry?"

Just for this question, He Rujun also fell into silence, frowning and thinking about it carefully.
