The president changed his career to become a detective

Leng Xuanang immediately said to the police officer: "Then please check how the coupon got into Wang Hongyi's hands?"

Police officers immediately began investigating the matter.

Through the investigation of the police officers, it was found out that the coupons were indeed issued by the supermarket, but these two coupons were bought by others.

Who bought the coupon?And gave the coupon to Wang Hongyi?This person was not found.

Because when this person went to buy coupons, he did not state his name.

Leng Xuanang thought about it, but let it go.Maybe this is Wang Hongyi's family, giving the old man a little surprise, or just showing respect to the old man in this way.

Leng Xuanang has been waiting for the identification of the strict forensic doctor.

Soon, the results of Yan's forensic examination came out.

Leng Xuanang looked at it, and it really is so!

The deceased Wang Hongyi died not because of a car accident, but because there was a small hole in his head, and a needle was inserted into it, and the needle has not been pulled out.So no blood came out.

Because the soft tissue of the head was stabbed with a needle, Wang Hongyi died just like that.

There is only a small hole in the soft tissue on the head, which is hard to find. With such skillful techniques, he is either a repeat murderer, a professional killer, or a doctor.

Otherwise, they would not have such a clear understanding of the structure of the human body.

Leng Xuanang dragged his cheeks and thought again and again, who did it?

Leng Xuanang immediately looked at Ni Tengfei and said, "Ni Tengfei, tell me again, who contacted the deceased Wang Hongyi?"

Ni Tengfei thought for a while, and several people appeared in his mind. Those who had contact with the deceased included himself, 120 first aid, and of course police officers...

Suddenly, Ni Tengfei thought of a person. This person was not someone else, but Gao Junchu.

He would be very nervous immediately, looked at Leng Xuanang and said, "I thought of someone, and that person is Gao Junchu."

Gao Junchu also passed the intersection at that time, and Ni Tengfei asked Gao Junchu to rescue Wang Hongyi.But Gao Junchu didn't rescue Wang Hongyi.

Ni Ruonan immediately spoke: "That's right! Gao Junchu is a medical student, so he naturally knows the soft tissues of the head and where they can kill. That's why he stuck the needle in the head."

After hearing this, Leng Xuanang nodded and said, "I probably understand. This matter is indeed a murder case."

Leng Xuanang explained the situation to the police officers, who immediately rushed to the male dormitory of the medical school.

The police officers arrested Gao Junchu and interrogated Gao Jinchu in the interrogation room.

But Gao Junchu refused to admit it.

Gao Junchu even sneered and said some ugly words to them.For example, they are so stupid that they can't even find a murderer, and they will associate a simple planning case with a murder case.

Gao Junchu refused to admit it even after beating him to death, so what should we do?The police officers got stuck here.

Leng Xuanang thought for a while, and there was no other way if he refused to admit it, the only way was to ask the police officers to call the traffic surveillance.

The case got stuck here. The president thought hard and started to investigate. Leng Xuanang investigated the person who bought the coupon, and it turned out that the person who bought the coupon was Gao Junchu.

Gao Junchu bought two [-]-yuan coupons and gave them to nearby resident Wang Hongyi.

And he told Wang Hongyi that there was a discount in that supermarket.And let Wang Hongyi go in the evening.Because I went too early, I haven't reached the discount time yet.

Wang Hongyi was very happy to receive two coupons, so he went shopping in the supermarket on time.But I didn't expect to be hit by a motorcycle at the intersection.

The traffic surveillance was quickly mobilized, and the police officers carefully watched the traffic surveillance. Leng Xuanang and Ni Ruonan also stood by and watched.

Sure enough, Gao Junchu caught a needle between his fingers, caught Wang Hongyi's head, patted it hard, and then put Wang Hongyi down again.

Wang Hongyi was knocked unconscious by a motorcycle, but died because of Gao Junchu's needle.

The case is finally cleared up.

Gao Junchu finally pleaded guilty.

Gao Junchu is a very clever boy, but he uses his cleverness in the wrong place.

He couldn't understand Ni Tengfei and Le Siling getting so close, the two of them interacted frequently, and his heart felt like it was being pricked by a needle.

He is not used to the woman he loves being so close to other men.

Gao Junchu learned that Ni Tengfei and Le Siling even decided to compete.

Gao Junchu hopes to create the illusion of killing people by chance to deceive everyone.

So he bought two coupons and specially invited an old man to pass the intersection in the evening.

He knew Wang Hongyi's greed for cheap, after all, this is not a little coupon, but two hundred.

Gao Junchu rented a car by himself, and watched Ni Tengfei and Le Siling's cars pass by on the road.

When he found Le Siling and Ni Tengfei's car rushing over, Gao Junchu's car rushed out too, he just wanted them to get out of the way.I just want Ni Tengfei to bump into Wang Hongyi.

His wishful thinking was right, he felt that this probability was really ingenious, because there was no external force.

Gao Junchu thought that the police would definitely think on the road of probabilistic killing, since probabilistic killing does not need to pay legal responsibility.

However, to his surprise, when he was rescuing Wang Hongyi, he found that Wang Hongyi hadn't died, and there was a possibility of him surviving.

Gao Junchu just wanted Ni Tengfei to be unable to hold his head up for the rest of his life. He wanted Le Siling, and he wanted Le Siling to lose Ni Tengfei forever.

He made up his mind very much, took out the needle that he carried in his pocket, put it between his fingers, and directly shot the dead man's head. In this way, Wang Hongyi was completely dead.

After he finished this matter, of course he was a little nervous.He hurried back to the bedroom.

Gao Junchu didn't expect that such a small move could be detected in the traffic monitoring.

After solving the case, Gao Junchu was punished by law.

Ni Ruonan and Leng Xuanang left the police station together.

Ni Ruonan looked solemn, looked at him coldly, and said, "What's wrong with you? Are you still immersed in the case? Don't forget that you are a detective, and your psychological quality is not good enough."

Ni Ruonan sighed, and said: "Gao Junchu is very powerful, it's a pity, he's too hateful."

"How do you say it?" Leng Xuanang relaxed, and did not answer the words.

Although Ni Tengfei was safe and cleared of suspicion, Ni Ruonan couldn't be happy.

"Gao Junchu intentionally caused chaos on the street, reported it, and asked police officer Quan to arrest Le Siling and Ni Tengfei and squat in the police station for a day, causing them to drive fatigued." Ni Ruonan sighed, "By increasing the risk factor in every link, To increase the probability of car accidents, Gao Junchu wants to use big data to kill people with probability."

Leng Xuanang looked at her seriously.

After a while, shaking his head, Leng Xuanang said: "Ruo Nan, from the perspective of quantum theory, all the momentum and variables in the universe cannot be accurately valued."

"What do you mean?" Ni Ruonan turned her head.

Leng Xuanang nodded, and then said: "Ruo Nan, Laplace's mechanical determinism itself denies people's free consciousness, and it is impossible to kill people by probability."

"Why?" Ni Ruonan had heard that Leng Xuanang had a high degree of education, but he did not expect to have such a wealth of knowledge.

Leng Xuanang frowned, and said, "Laplace's law is only valid under ideal conditions."

Ni Ruonan didn't understand, and asked, "Oh?"

Leng Xuanang waved his hand and said, "Gao Junchu's calculated probability is not equal to the facts. In actual operations, there are many variables that cannot be calculated by using formulas."

"Then do you mean that Laplace's Law is wrong?" Although Ni Ruonan had a university degree and a bachelor's degree, she couldn't understand it.

Leng Xuanang nodded, looking very knowledgeable, and replied: "Laplace's law was overthrown by quantum mechanics as early as the beginning of the [-]th century."

Ni Ruonan finally understood!

"I know, so Gao Junchu used the probability to kill and failed. He prepared a needle and stabbed the soft tissue of the dead man's head! That's a perfect crime!"

Ni Ruonan seemed to be summarizing Gao Junchu's crime methods at the end.

Leng Xuanang laughed and said, "No, he didn't commit a perfect crime. Forensic doctor Yan is better."

Ni Ruonan nodded, a little more admiration for Leng Xuanang.

At the crossroads, the two parted ways.

Ni Ruonan sent his terrified younger brother Ni Tengfei back home.

Ni Ruonan came to the door of the house, but still did not enter the house.Seeing his younger brother Ni Tengfei enter the house, he left with peace of mind.

And Le Siling, who was also frightened out of her wits, also returned home.

After this incident, Le Siling has changed, and today's Le Siling has become very silent.Because she experienced a very terrible thing today.

Le Siling didn't even think that this seemingly gentle and gentle person could be so vicious.

Leng Xuanang came to the hospital and reported the whole process of the case to Police Officer Quan.

Officer Quan stretched out his hand, patted Leng Xuanang on the shoulder twice, and said, "You have done a good job, do it well in the future, or you can resign from the position of president and do it with me? I am lacking How about an assistant like you?"

Leng Xuanang smiled wryly, shook his head and said: "I also like to investigate cases, but the responsibility my family gave me is to be the president. I have no choice."

Officer Quan shook his head and stopped talking about it.

Officer Quan seemed to have thought of something suddenly, and said to Leng Xuanang: "Ni Ruonan also put a lot of thought into this case, thank you girl for me."

Leng Xuanang nodded and said, "Of course. However, I have already thanked her."

Chief Leng Xuanang didn't understand what Police Officer Quan meant. Police Officer Quan just wanted to promote the relationship between the two of them.

Because Officer Quan found that these two people were actually quite suitable.The main reason is that Ni Ruonan is working too hard. If the two of them can get along well, Officer Quan will of course be very happy.

Officer Quan saw that Leng Xuanang was not enlightened at all, sighed, then shook his head, and said, "Leng Xuanang, do you really not understand what I'm talking about?"

Leng Xuanang looked at Officer Quan with a puzzled face and said, "Officer Quan, what do you mean? I..."

When Leng Xuanang said this, suddenly, a person appeared at the door of the hospital ward. This person was none other than Ni Haohan.

Ni Haohan walked in with a bouquet of flowers.

　She put a bouquet of flowers in front of Officer Quan, sat down without speaking.

Police Officer Quan has been staring at Ni Haohan. Although Ni Haohan's every move is not very friendly, Officer Quan seems to be more and more pleasing to the eye, and feels that watching Ni Haohan is a kind of enjoyment.

Police Officer Quan also came alive, looked at Ni Haohan, and said, "Mr. Ni, if you send me flowers, you can send them flowers. Why are you still holding back?"

Ni Haohan put the bag on the hospital bed, then picked it up again and put it on the table next to him.

Why did Ni Haohan do this?
