In the morning, Xue Gang's mobile phone was not idle at all, all of them were classmates calling to care and greet, and they were relieved to learn that Xue Gang's condition had stabilized, and at noon, Lin Fang and Xu Zijun visited the hospital, and just brought food, and the four of them ate a little in the ward.

At three o'clock in the afternoon, the ward ushered in the second wave of guests, who turned out to be Ning Anmin, director of the Jinning Municipal Public Security Bureau, followed by the dean and several doctors.

"Doctor Chen, Director Ning of the Jinning Municipal Public Security Bureau has come to see you. The dean took the lead in pushing open the door and introduced.

Ever since Chen Heal entered this hospital, all the great gods have come to report, and the dean can no longer imagine how powerful Chen Heal's background is.

"Director Ning, hello. Chen Hell got up to greet Ning Anmin, Xue Gang didn't expect that his case would actually alarm the director of the Jinning City Public Security Bureau to come to visit in person, and tried to get up, but the pain was unbearable, and he really couldn't do it, so he could only lie on the bed obediently and thank Ning Anmin.

"Classmate Xue Gang, don't be polite to me, you are still very weak now, and the main task is to recuperate well and strive to be discharged from the hospital as soon as possible. Ning Anmin waved his hand to Xue Gang and put the flower basket and nutritional products in his hand on the side of the bed.

"Doctor Chen, after receiving the instructions of the secretary and the mayor, I personally led people to take immediate action and follow the clues you provided all the way, and now that the situation of the case has been clarified, can you come out for a while, let's talk. Director Ning said.

"Good. Chen Zhizhi nodded.

"Wait, why go out? Just say it here, I think since it's about me, I should have a right to know the truth. Xue Gang stopped.

"This ...... Xue Gang, the case is a bit special, and you will know sooner or later after you are cured and discharged from the hospital. Director Ning said.

"Captain, I know that you have a lot of energy, and the director doesn't listen to me, but I definitely listen to you, you help me beg the director, just say it in front of me, my tolerance is not so bad, and I generally know who wants to harm me. Xue Gang said.

"Oh, can you guess?" Chen was also curious.

"Today, I've been waiting for someone, according to my relationship with him, something must have happened to me when such a big thing happened to me, and he didn't come to see me. Xue Gang said with a gloomy expression.

"In that case, Director Ning, please excuse me, just say it here, no need to avoid it. Chen Heming thought for a while and said.

"Okay, anyway, Xue Gang will know sooner or later. After investigation, Dr. Chen, your judgment is completely correct, and the person who poisoned him was Xue Gang's classmate Tong Han. Director Ning said.

"It's really him......" Xue Gang leaned on the pillow with a dejected expression, revealing a painful expression.

"I know he's jealous of me, we've both grown up together, but he's always felt that I'm better than him in every way, and God is unfair to me and to him, and people say that jealousy makes people crazy, and it seems to be true.

But I've really always treated him as a good brother, thinking about him for any good thing, and never feeling that he was better than him, why can't he think about it like this. Xue Gang said dejectedly.

"Director Ning, let's tell me the whole case in detail. Chen Cheng patted Xue Gang on the shoulder and said.

"Okay, when I received the case, the test results from the Market Supervision and Administration Bureau also came out, and there was no problem with the food and drinks you ate that afternoon, and Zhongzhou International Hotel could completely clear the suspicion.

Later, I personally led someone to find Tong Han's home, at that time, Tong Han and his mother had already rested, after I explained my intention, Tong Han's reaction was a little abnormal, but he still followed us to the police station for investigation, and Tong Han's mother also accompanied him.

After arriving at the police station, I personally communicated with Tong Han, and slowly found clues from his words, and then with the help of Dr. Chen's inference, I directly restored the truth of the case, and told Tong Han that we have sufficient evidence to prove that he is the murderer.

Tong Han soon collapsed, and explained in detail the motive and process of the crime. The circumstances of the crime are completely consistent with Dr Chan's inference. Tong Han learned the basic principles of poisoning from a high-IQ crime movie, and he innovated himself.

There are three main components of toxins, one is Substance X, one is Substance Y, and the other is alcohol. Among them, substance X contains highly toxic and is the most important ingredient, while substance Y is not toxic in itself, but after a chemical reaction with alcohol, it will evolve into highly toxic, and at the same time, the evolved highly toxic will further react with substance X again, resulting in the complete dissolution of the two highly toxic substances in a certain period of time without a trace.

According to Tong Han's own confession, his goal was only to poison Xue Gang's classmates, and he knew that Xue Gang would inevitably drink liquor at every party, so he thought of this method, because the alcohol content of beer was very low, which was not enough to trigger this series of reactions.

What Tong Han never expected was that Dr. Chen would also choose to drink liquor, and what he didn't expect was that Dr. Chen was actually an invulnerable body, and he also had the best medical skills, not only immediately administered needles to Xue Gang, but also tested the components of the toxin in the shortest possible time, breaking his entire plan.

If it weren't for Dr. Chen's involvement, by the time everyone found out, Xue Gang was already dead, and the toxin had been completely ablated, and it couldn't be tested at all, so even if someone suspected him, they wouldn't be able to produce conclusive evidence. Director Ning said.

"I don't want to hear what happened to the crime, can the director tell me why Tong Han killed me?" Xue Gang asked.

"Hey, it's a long story, there are some things you know, but some things you don't know yet, and listen to me slowly. Director Ning sighed.

The cause of the incident also made him feel very helpless.

"Your dad and Tong Han's mom were high school classmates and were each other's first lovers. But later, Tong Han's mother's college entrance examination results were very unsatisfactory, and the family conditions were not good, so she chose to drop out of school and work in our textile factory in Jinning City.

And your father was successfully admitted to the university, and married your mother after graduation, your grandparents' family conditions are very good, with their help, your father's business is getting bigger and bigger, and it is getting better and better, so that today's achievements have been achieved, even I, the director of the Public Security Bureau, have long heard of your father's name.

Five years ago, Tong Han's father, who was also an employee of a textile factory, died in an accident due to a production accident, and Tong Han's mother took Tong Han's hard life, and since then, your father has been secretly helping their mother and son.

Slowly, the flame of love between the two first lovers was rekindled, and Tong Han had seen your father and his mother making love together many times, which made Tong Han very devastated.

In Tong Han's own words, your family already has everything, and now, your father is going to take away his only mother, so Tong Han hates you and your family, he wants to poison you, let your father and your mother taste the loss of their relatives, and make your father pay for what he did. Director Ning said slowly.

"No! This can't be! How could my dad be with Tong Han's mother! My dad and my mom have a good relationship, how could he cheat, you don't want to lie to me!" Xue Gang shouted angrily with red eyes.

"Xue Gang, don't be excited, I am a police officer, and I am the director of the Public Security Bureau of Jinning City, if there is no sufficient evidence, how dare I open my mouth?

Just this morning, we have found your father and Tong Han's mother to confront each other, they have both admitted the above facts, and now, they are still in the police station, waiting for a more delicate record. Director Ning said.

"How could this be, why! I didn't know that my father and Tong Han's mother were high school classmates, and they were each other's first love, but that was a long time ago, they were already married and had their own families, how could they still do such a thing!" Xue Gang couldn't accept it at all.

"That's the way it is, when I learned that Tong Han poisoned you, Tong Han's mother has broken down, and your father is also very painful, and they don't know how to face you, so I am going to come to Dr. Chen to discuss first. Director Ning said.

"My father and Tong Han's mother shouldn't be considered criminals, right?" Xue Gang asked.

"Of course not, if you want to talk about criminals, Tong Han is the only one here, and your father and Tong Han's mother are just cooperating with our investigation. Director Ning hurriedly shook his head.

"Then can I meet my father?" Xue Gang continued.

"Yes, we don't restrict your dad and mom from having a free life, you can contact them at any time. Director Ning said.

Subsequently, Xue Gang called his father, Xue Guigui.

Xue Guigui apologized to Xue Gang on the phone and cried bitterly.
