The Case of Love

Chapter 5: Guilty Heart
After some screening, Zhou Yifeng and his colleagues finally found Xu Yongfeng in the surveillance video a few hundred meters outside the hospital.

Although it was past ten o'clock at night, the light from the street lamps was still good, and they could see clearly that Xu Yongfeng threw a white paper bag into the trash can.

"There are so many trash cans in the hospital, but he chose to run so far to throw things away. There must be something wrong!" Su Xiaohan sighed.

"That's right, go check this trash can and see if the water cup is still there!"

Time was running out, and Zhou Yifeng was afraid that the sanitation workers would take away the garbage, so he walked out. Su Xiaohan and Ma Nan followed him quickly.

Perhaps because the location was remote, there were not many things in the trash can, and the sanitation workers had not collected the trash yet, they soon discovered the white paper bag in the surveillance video. As they expected, the paper bag contained a thermos cup, in addition to the thermos cup, there was also a medicine bottle filled with unknown liquid.

"Hurry back to the bureau for testing!" Zhou Yifeng was very excited to get results so quickly.

On the way back to the bureau, Zhou Yifeng received a call from the person who was sent to Xu Yongfeng's home to check. In Xu Yongfeng's home, he found some mineral water bottles filled with unknown substances. Zhou Yifeng asked him to bring the things back to the bureau and test them together with the things they brought back.

In the afternoon, the test results came out, and the residues on the medicine bottles and water cups they brought back were exactly the same as the toxic substances in Guo Zhigang's body. In other words, Xu Yongfeng was the poisoner.

Faced with the evidence, Xu Yongfeng had to bow his head.

"I didn't want him to die. I just wanted him to be unable to go to work. I didn't expect him to commit suicide." In the interrogation room, Xu Yongfeng began to defend himself.

"Tell me, what did you do?" Zhou Yifeng asked.

"Once, when I was taking medicine, he asked me what was wrong, and I told him that my blood sugar was a little high. He said that his blood sugar was also a little high, but he couldn't take insulin because of a hormone allergy. I didn't pay attention at the time, but later I thought, since he had high blood sugar and was allergic to hormones, I might as well secretly add a little sugar and hormones to his body, and then prepare some injection solution, so that he could suffer from chronic poisoning. When his body slowly develops some symptoms and he can't come to work, he may lose his position as director, and I can take over." As he spoke, Xu Yongfeng's eyes fell on the table, and he didn't dare to look up at Zhou Yifeng and Su Xiaohan.

"How did you mix those things, and how did you get Guo Zhigang to drink it?" Zhou Yifeng asked sternly.

"I prepared sugar, mineral water bottles, injections, and the hormone drugs I took, mixed them and added a small amount of water. After the morning meeting every day, I poured these things that looked like water into Guo Zhigang's thermos cup before he came back."

"Guo Zhigang has been drinking what you prepared. Didn't he notice anything unusual?" Zhou Yifeng asked.

"Once, when he was drinking water, he felt it was a little sweet. He asked me, and I said I thought so too, and maybe this batch of purified water all tasted like that. Later, I reduced the proportion of sugar so that he would not notice anything." At this point, Xu Yongfeng's expression changed a little.

Su Xiaohan sighed in his heart. They were in the same office, and Guo Zhigang trusted him so much, but he only wanted to harm him.

"Xu Yongfeng, you poisoned your former student just because you wanted to take his place?" Su Xiaohan said angrily. "I didn't poison him. This thing can only make his health worse, it won't harm his life!" Xu Yongfeng argued, "Besides, what kind of student is he? How can a student climb up by stepping on the shoulders of a teacher!"

When the truth came to light, Xu Yongfeng finally vented his pent-up resentment in front of the police and recalled his past with Guo Zhigang.

Six years ago, Guo Zhigang, who was just an ordinary doctor at the time, was transferred from another place to work in the Department of Cardiosurgery of Beijing Central Hospital. Thinking of Guo Zhigang's arrival in Beijing, Xu Yongfeng, who was then the deputy director, gave him a lot of help both in work and in life.

Guo Zhigang was very grateful to Xu Yongfeng for his generous teaching, and the two gradually became master and apprentice from ordinary colleagues. Guo Zhigang sincerely thanked Xu Yongfeng and would invite him to his home for dinner during holidays, which made Xu Yongfeng feel very accomplished.

Xu Yongfeng has high aspirations for his career. He has always hoped that the director of the Department of Cardiac Surgery would be promoted, so that he, as the deputy director, would have the opportunity to be promoted to the director of the department. Two years ago, the opportunity Xu Yongfeng had been waiting for finally came. The original director of the Department of Cardiac Surgery was promoted to the hospital leader, and the position of the director of the Department of Cardiac Surgery was vacant, so Xu Yongfeng naturally had the opportunity to be promoted.

However, the hospital adopted an open registration and competition method for the position of director of cardiac surgery. As expected, Xu Yongfeng signed up, and his apprentice Guo Zhigang also signed up.

Thinking of his achievements over the years, Xu Yongfeng was very confident, and he also had a good relationship with the cardiac surgery staff. After the exam, he was not worried about being rejected, and just waited for the office website to announce his appointment as the director of cardiac surgery.

When the hospital leader told him that he was not the director of cardiac surgery, he couldn't believe his ears. He even looked at the appointment notice on the hospital's internal website, which clearly showed the name "Guo Zhigang". Xu Yongfeng felt resentful, regretful and angry.

Xu Yongfeng regretted teaching Guo Zhigang everything he knew and gradually became jealous. Even after Guo Zhigang took office, he still respected him and regarded him as a teacher, but he still disliked him more and more. Moreover, since Guo Zhigang became Director Guo, he became more and more strict in his behavior, especially in meetings, he would reprimand colleagues who made mistakes at work.

Gradually, Xu Yongfeng's hatred for Guo Zhigang reached its peak. On the one hand, he was jealous that Guo Zhigang could directly become the department director he had long coveted. On the other hand, he felt that the power Guo Zhigang had should belong to him. Therefore, he hated being with him more and more.

That day, he accidentally learned that Guo Zhigang was allergic to hormones and sugars, and he came up with the idea of ​​making him unable to work and taking his place. He imagined that if Guo Zhigang was gone, he would be very comfortable and at ease at work.

He used his knowledge of pharmacology to prepare drugs that would harm Guo Zhigang's body. At first, he just thought that he could not come to work in the cardiac surgery department, and later, he had the idea of ​​kicking Guo Zhigang out of the hospital completely.

Almost every morning after the meeting, Xu Yongfeng would add this liquid that was harmful to Guo Zhigang's health into his drinking water. As time went by, Guo Zhigang's health deteriorated and eventually declined to the physical condition of a 70-year-old man.

Although Xu Yongfeng did not directly kill Guo Zhigang, it was his repeated poisoning that caused Guo Zhigang's health to deteriorate. Unable to bear the torture of the disease, he chose to commit suicide.

At the end of the interrogation, Xu Yongfeng confessed to what he had done and the case will be transferred to the court for trial.

Coming out of the interrogation room, Su Xiaohan felt extremely depressed. In her eyes, doctors were as holy as angels, but angels had sinful hearts and were scarier than demons.
