Zhang Yang accompanied Yu Qianghua to find Yang Yue'e.

After hearing Yu Qianghua reveal his identity, Yang Yue'e did not show any panic expression on her face. She said calmly: "What are you looking for me?"

Yu Qianghua said: "You should be familiar with Guan Cheng, right?"

Yang Yue'e said: "I know, but I'm not familiar with it."

“Based on what we learned, he is your ex-husband.”

Yang Yue'e said: "It's not bad, it's my ex-husband, but this does not mean that I am familiar with him. If I were familiar with him, we wouldn't have reached the point of divorce."

Yu Qianghua said: "We came to you today to find out some of the situations about Guan Cheng."

"Do I need to repeat it? I have been divorced from him for twelve years, and I don't know what he has been doing in these twelve years."

Yu Qianghua said: "When you got married, did you understand what he was doing?"

"He told me that I was a salesman." Yang Yue'e's expression seemed a little impatient.

Yu Qianghua looked around the office, walked to the reagent bottle containing hydrogen peroxide, and whispered: "Hydrogen peroxide, every hospital has such disinfectant, so the dosage must be very large, right?"

Yang Yue'e said: "It is rare to know disinfectants that are so ordinary that they are not ordinary, with your professional knowledge." Her words were full of sarcasm.

Yu Qianghua didn't mind her sarcasm and smiled: "The hospital has strict rules and regulations on the use of these drugs. It should not be difficult to find out the specific dosage, right?"

Yang Yue'e said: "What are you doubting? If you want to see it, I can show you the detailed records of entry and exit, but there is a prerequisite that you must get the signature of the dean first."

Yu Qianghua's eyes were attracted by the duty schedule on the wall, and he whispered: "You are one night shift for seven days."

Yang Yue'e said: "Is this related to you?"

Yu Qianghua smiled and said nothing. He winked at Zhang Yang and the two of them said goodbye and left.

Zhang Daguan Ren felt that Yu Qianghua's question had not made any breakthrough progress, and he was unwilling to say, "Just leave like this?"

Yu Qianghua said: "She is very calm and has been deliberately guarding since she met us. It is difficult for such a person to ask what he can do."

Zhang Yang said, "Why don't I try it." He was quite confident in his ecstasy.

Yu Qianghua pointed to the monitoring in front of the reagent room door. The hospital has monitoring for such departments. As long as Guan Cheng visited Yang Yue'e recently, records should be found on it.

Yu Qianghua came to the hospital's security department because it was his jurisdiction. The security department chief was very familiar with him. He heard that Yu Qianghua wanted to investigate the case, so he naturally cooperated with them and opened the door to convenience.

Yu Qianghua's intuition was not wrong. When Yang Yue'e was working on night shift two weeks ago, someone did come to visit her. According to preliminary comparisons, that person was her ex-husband Guan Cheng.

Yu Qianghua paid attention to evidence in everything. After obtaining this evidence, he returned to the reagent room.

When Yang Yue'e saw Yu Qianghua return, her face changed a little. Yu Qianghua didn't beat around the bush and put the evidence directly in front of Yang Yue'e. Faced with the facts, Yang Yue'e had to lower her head and whisper: "Yes, Guan Cheng did find me two weeks ago. I didn't lie. I haven't seen him for many years before I met him this time."

Yu Qianghua said: "What did he ask you for?"

Yang Yue'e bit her lip and finally said, "He asked me for some hydrogen peroxide and said it was for disinfection, so I gave him some."

Yu Qianghua said: "Are you asking for anything else to do besides hydrogen peroxide?"

Yang Yue'e said: "No, really not!"

Yu Qianghua said: "Do you know where he lives now?"

Yang Yue'e said: "I haven't seen him for almost ten years. I don't know anything about what he did during this period and what job he is doing now. We have long lost our feelings. Has he done something bad?"

Yu Qianghua said: "Apart from you, do Guan Cheng have any relatives in the capital?"

Yang Yue'e shook her head and said, "He has two sisters, one in Hong Kong and the other in France. Her parents have long died, and there seems to be no one in the other family."

Yu Qianghua said: "Does he have other friends?"

"He has no friends!" Yang Yue'e said decisively. After saying that, she seemed to remember something: "By the way, he has an uncle, not his biological uncle, but his father's friend, named Li Shangzhi. He told me that that person was the only one of his father's friends who helped him. I remember this person's name very clearly, and there is no mistake, because when we got married, he specially drew a painting and gave it to us, and also gave us an electric fan."

Yu Qianghua and Zhang Yang looked at each other, and both felt that Yang Yue'e was not lying. She had hydrogen peroxide in the pharmacy department, but there was no acetone. In other words, Guan Cheng might have obtained hydrogen peroxide from her. Another material was obtained from another place. Yang Yue'e should have been really blinded by Guan Cheng and did not know what he wanted to use the hydrogen peroxide he provided to him to do.

Yu Qianghua continued: "Do you know where Li Shangzhi lives now?"

Yang Yue'e shook her head again and said, "After I divorced Guan Cheng and I broke off contact with everything around him. Li Shangzhi did find me once five years ago. He asked me to help with the doctor, but he never came again."

“Hosted?”

Yang Yue'e thought for a while, nodded and said, "Yes, she was hospitalized. She lived in the cardiology department at that time. Because the bed was tight, he asked me for help."

As long as he is hospitalized, his medical record should be found, and it should not be difficult to find Li Shangzhi's address from the medical record.

It is definitely the right thing to do to ask Yu Qianghua for help. Yu Qianghua not only does things seriously and meticulously, but also has a strong sense of justice.

After searching in the medical record room, it was found that Li Shangzhi lived in a place not far from Xijing District People's Hospital. It is located in the dormitory of the paint factory about one kilometer southwest of the hospital. The paint factory has long gone bankrupt. Now only this dormitory area is left. Due to the long-term lack of effective management, it seems dilapidated and illegal buildings can be seen everywhere.

Yu Qianghua and Zhang Yang came to the dormitory and found an old man to ask about Li Shangzhi. However, they were told that Li Shangzhi had been dead for three years, but his son Li Weijun still lives here. Li Weijun is not at home. He usually operates paint and paint in Xixing Market.

Yu Qianghua has basically locked in on the person who Li Weijun is likely to provide Guan Cheng with propanol.

The warm afternoon sun was so sleepy that it made people drowsy. Li Weijun lay on the counter and was dozing. Suddenly, he was awakened by the noise of someone slapped at the counter. He opened his sleepy eyes and blinked and said, "What's the matter? What are you going to buy?"

Zhang Yang came to look for him, but Yu Qianghua did not show up immediately because he was worried that he would be recognized.

Zhang Daguan Ren pretended to be mysterious, looked around and lowered his voice and said, "Propanol!"

Li Weijun was stunned for a moment, then grinned and said, "Brothers, what do you want that thing?"

“Mix the paint!”

Li Weijun said: "Wang, the water is so good, it's much better than that thing."

Zhang Yang said: "I said why are you so urinating? I just want to use propanol."

Li Weijun laughed and said, "Brothers, if you have spread all over Xixing, no one will sell your stuff. Do you know that it is within the control scope now? Let's go quickly. I don't have that thing here, and I won't do anything that violates the policy."

Zhang Yang said: "Brothers, who are you tragically? I can find you, but it's not like I'm here by chance. Can you sell it to others, but not to me?"

Li Weijun was stunned when he heard this: "Who have you heard nonsense? I never sell that thing."

Zhang Yang said: "She*** pretends to be garlic for me, Brother Guan introduced me to me."

When Li Weijun heard him say this, his expression on his face was skeptical. He looked at Zhang Yang and whispered: "Why don't Brother Guan come here by himself?"

Zhang Yang said: "If such a small thing is enough, can he come here in person?"

Li Weijun smiled and said, "That's true, but you have to let him call, right?"

Zhang Yang said: "Can't you trust me?"

Li Weijun said: "We have never met before, so you can't say what you say? Call Brother Guan and ask him to tell me in person."

Zhang Yang said: "It seems you really forgot me, take a closer look at me."

Li Weijun indeed looked at his face. It would be fine if he didn't look at it. After seeing it, he was immediately attracted by Zhang Yang's eyes. He only felt that Zhang Yang's eyes seemed to be full of magical power. After seeing it, he could no longer be able to get out of his eyes. He felt that his thoughts seemed to be moved by the other party's eyes.

Official Zhang smiled slightly and said, "What is Guan Cheng's phone number?"

Li Weijun reported his phone number in a daze.

Zhang Yang said again: "When was the last time you met him?"

Li Weijun said: "Half a month ago, Brother Guan asked me to get some propanol and some other things."

"Do you know where he currently lives?"

Li Weijun said: "I don't know, but Brother Guan said that if I encounter any trouble, I will ask me to find Geng Qianqiu, the boss of the Palace of the World, and say that she will help me."

Zhang Yang nodded with satisfaction and nodded to a black Santana not far away. Yu Qianghua, who was hiding inside, immediately understood that Zhang Yang had succeeded, and he notified his subordinates to take Li Weijun back to the police station.

Zhang Daguanren returned to Yu Qianghua's car and told him the news he had just heard. When Yu Qianghua heard Geng Qianqiu's name, he couldn't help frowning: "Geng Qianqiu, do you know who this person is?"

Zhang Yang said: "I haven't heard of it."

Yu Qianghua said: "You tell Guoqiang first, maybe he can help you in this matter."
