Wang Lu still had doubts in her heart: "But isn't the raw materials purchase of the processing plant a fake account?"

"That's right, but sometimes this account is really impossible to check. For example, you are the boss of a canning factory. The fresh fruits and vegetables you need for production are purchased directly from farmers and do not rely on third parties. Then when purchasing the raw materials, you only need to go to the tax authority to issue an invoice. Of course, you must bear a certain amount of tax. After all, farmers cannot issue an invoice to you. In this process, as long as your factory does not have any problems with taxation and strictly abide by the accounting system stipulated by the state, there will be no problems in the book of your factory. Now you understand?"

Wang Lu nodded at this time. Although it was a bit complicated, she still understood a little.

"As for other links, agency companies, trading companies and dealers, it is much simpler. The purchase and delivery are reflected on the books, and the income and expenditure are real on the books, and the tax that should be paid is also a lot. Who will check you if you have nothing to do? If you can do it well, you can become an advanced tax model!"

Wang Lu widened her eyes: "This He Chuan is really capable."

Shen Chen nodded. Although he had only contacted He Chuan for so many times, he had to admire He Chuan's brain for being useful. He actually thought of using this method to cover himself up and also whitewashing the shameful money.

"In fact, He Chuan's method seems clever, but there are still problems. If his trading company's business is not so single, I wouldn't have thought of so much, let alone doubt that there is such a closed-loop production and sales chain. Lao Xiao has been to his trading company. Judging from the operation of the trading company, everything is normal and he can't find any problems at all. The anti-drug side was also obscured by a leaf, but I believe that even without our help, they would sooner or later find this loophole. But then again, He Chuan's background is so complicated, which has added a lot of difficulty to us to solve the case."

Wang Lu didn't say anything.

Shen Chen continued: "In this way, Qi Hua's motive for killing He Chuan becomes difficult to understand."

As he was talking, Shen Chen's cell phone rang.

It was Tan Ke who called him, so he asked Shen Chen to go to his office immediately.

Shen Chen came to Tan Ke's office, and Tan Ke was looking at a file.

"Come on, look at this!"

Shen Chen took it and looked carefully. After reading it, he looked up at Tan Ke: "This is a case from thirty years ago."

Tan Ke nodded with a serious expression: "Thirty years ago, I was working in a rural police station. At that time, I vaguely heard about this case, but I didn't have much to do with me, so I gradually forgot it. After the Yin Hui case, I always felt that the murderer's method of murder was familiar, but I couldn't remember it for a while. If it weren't for the lunch with Lao Feng, he mentioned this case thirty years ago when he mentioned it."

"Old Feng?" Shen Chen was stunned.

Tan Ke smiled: "It's your Uncle Feng, Feng Hu!"

Shen Chen didn't expect Tan Ke to have lunch with Feng Hu.

Tan Ke said: "There is another thing you probably don't know. The case was handled by your father. Not long after he joined the criminal police team, he and Lao Feng had just started to partner, and this was the first case he got!"

Tan Ke said lit a cigarette, and the smile on his face disappeared: "But they were unable to solve the case in the end. This case is a regret for your father and Lao Feng."

One night thirty years ago, Lin Zhi, a doctor at Lincheng Second People's Hospital, was killed at his home and was stabbed into his temple by a knife while he was asleep. His wife was awakened on the spot. She turned on the light and saw a monkey jumping out of the window and running away with a knife.

The crime was committed by a monkey.

The information at that time was not as developed as it is now. Because this case was very special, it did not spread to the outside world, and not many people knew about it.

At that time, the police were not completely convinced by Lin Zhi's wife's words, because no evidence was found at the scene that Lin Zhi was killed by a monkey. Some people suspected that Lin Zhi's wife was a thief and called to catch the thief, while others suspected that Lin Zhi's wife was frightened at that time and did not see clearly the murderer's appearance.

However, Chen Shen's father believed Lin Zhi's wife's statement, but after investigation, nothing was found.

Lin Zhi's wife also became neurotic and had the delusion of being killed. She would be frightened if she was a little disturbed. She was particularly afraid of seeing the monkey. Finally, she went to the mental hospital. It is said that after she was cured, she left Lin Cheng's sad place.

"You can take it and take a look, maybe it will be helpful to the case in your hands."

Chenchen returned to his office with the file, but Wang Lu had not left yet.

Wang Lu is from the Provincial Department. In fact, her mission in the task force should have been completed, but she wanted to follow up on the entire case. She told the leaders of the Provincial Department that she lacked actual experience in handling cases, which would be of great help to her future work, so the leaders of the Provincial Department agreed to her request.

"What did Director Tan ask you for?" Wang Lu asked curiously.

Chen Chen handed her the file, and she looked at it seriously. After reading it, she was shocked: "In other words, the murderer in our case is likely to be the same person as the murderer in this case thirty years ago?"

He shook his head heavily: "It's hard to say, but there must be something in it."

"The second doctor in the city, doctor, doctor of neurology!" Wang Lu murmured to herself, but a light flashed in her eyes: "I understand!"

Wang Lu didn't know why Chenchen was shocked, but Chenchen had no explanation. She picked up her mobile phone and asked Xiao Qiushui and the others to check it out. In which hospital Qi Guangyu's father was diagnosed with ALS and who was the doctor in charge of treating him.

Although it was a bit difficult to check, Xiao Qiushui found it quickly. After about an hour, he received a message from Xiao Qiushui: "The second doctor in the city, he lived in the second doctor in the city for about two months, and then he had to make a fuss about being discharged from the hospital. Not long after he was discharged from the hospital, he committed suicide. His attending doctor was named Lin and named Lin Zhi, but he had been dead for many years."

"Which year did Qi Guangyu's father be hospitalized in the second hospital in the city?"

"In 1984, he also committed suicide that year. Lin Zhi died in 991. I heard that his death was a bit strange. It was said that his wife killed him, but his wife later went to a mental hospital. Alas, there are all things he said. It has been so many years since then. Those who know about this are all elderly people in the hospital and can't remember many things. However, when Qi Guangyu's father was hospitalized, the hospital can still find the medical records of that year."

"Can you still find it?" Chen Chen was a little surprised, and Xiao Qiushui smiled and said, "Well, I think it's strange, but the retired old director later said that his illness was a bit rare and uncommon at that time, so he saved it as a special case. However, the old director said that Qi Guangyu's father's diagnosis might have some problems."

He hurriedly asked, "What's the question?"

"It may be a misdiagnosis. The old dean said that he later asked experts from Beijing to see all his medical records. His condition was more like a result of psychiatric disorders."

A deep smile: "Psychomatic? Then this misdiagnosis is a bit unreasonable."

"Not that, the old dean also said. At that time, he also thought it was ALS because the patient's limb speed lost its ability to move in a very short period of time, and the physical examination did show symptoms such as hyperreflexia and increased muscle tone. However, experts in Beijing said that this may be caused by the patient's psychological factors. The expert in Beijing said that the patient may have a serious hypochondria mentality, so after Lin Zhi misdiagnosed, he imagined his symptoms in his heart. I heard from the old dean that when Lin Zhi said that he might have ALS, he didn't know where he got some books about this disease, and the more he read it, the more he felt that he was the same as the one written in the book."

He didn't speak, but he knew in his heart that if the judgment of the experts in the capital was correct, then Qi Guangyu's father was a person who was easily suggestive. Lin Zhi's misdiagnosis made him accept the suggestion, and then he tried hard to imagine himself as a patient, and he was afraid that he would not be like him, so he made this book to make himself look like that. In the end, he naturally felt hopeless, afraid of dragging down his family and ending his life hastily.

This kind of hypochondriatic psychological case is not uncommon, but it did not attract attention in the 1980s. It was the late 1990s that the real emphasis on psychological problems was still in the late 1990s.

After hanging up the phone, what I was thinking about in my deep mind was no longer about Qi Guangyu's father, but Lin Zhi's death.

Lin Zhi's death was seven years apart from Qi Guangyu's father's suicide in terms of time. If Qi Guangyu and Qi Hua both knew how to control monkeys, then Lin Zhi's wife saw that monkeys were killed was largely due to Qi Guangyu's actions. Qi Hua was not born at that time.

There is only one reason why Qi Guangyu attacked Lin Zhi, that is, he knew that his father was misdiagnosed, because Lin Zhi's misdiagnosis eventually led to his father's suicide. In his opinion, the culprit of his father's death was not a disease, but a quack doctor. He must have hated Lin Zhi in his heart because Lin Zhi caused his father to end his life in such a disgraceful way. He was revenge on Lin Zhi and using his own means.

But what happened to Qi Guangyu's ALS? Is it true or false?

Chenchen left the office and he called out Wang Lu.

"Let's go, let's go to Qi's family again." He felt that he should have a good talk with Qi Guangyu, just talk about the case of Lin Zhi thirty years ago.

After getting in the car, Wang Lu asked, "Is there any news about Team Xiao?"

Chen Chen told Wang Lu about Qi Guangyu's father, and Wang Lu sighed: "If this is the case, Qi Guangyu's father will die unjustly. However, people like this who have hypochondriasis are really unreasonable. I encountered one of them when I was internship. Once, I coughed for two days because of a small cold, and he felt it was amazing. He doubted whether there was a problem with his lungs. Guess what he was doing?"

"What's wrong?"

Wang Lu said: "He went to Baidu by himself. After he read all the coughs in Baidu, he felt that he might have lung cancer. In fact, he had a small cold. We explained to him many times, but he just didn't listen. He thought we were lying to him. Especially once, he asked the doctor who treated him if he needed to pay attention to his usual exercise and diet. The doctor said he didn't need to pay attention and he would do whatever he should do. He became even more panicked. He thought he had no time left, was worried and depressed all day long, and finally had mental problems. This type of person is a susceptible person, and he easily accepted internal or external psychological hints."

He nodded heavily, and he naturally knew what Wang Lu said.

Wang Lu said again: "But one thing is very magical. You should have heard of the most famous psychological experiment, right?"

She looked at her deeply and smiled: "Take a person to the interrogation room, let him see a very burning stove, then blindfold his eyes, and then fix his body, through the hint of words, let him know that the red-hot iron would be burned in his hands, and in his struggle, the experimenter used a soldering iron that had not been heated at all, and soon the miracle happened."

Chenchen took over the conversation, and he had indeed heard of this experiment: "The arm of the experimenter is really red, and the place where the soldering iron is touched by the room temperature is red as if it has been burned, and even blisters appear."

Wang Lu put away her smile and said seriously: "Yes, this experiment is real. What I want to say is that the patient not only had mental problems in the end, but also had lung cancer! It took him almost half a year to get a small cold to lung cancer. His disease can be said to be completely thought of by him. Isn't it very magic?"

He sighed heavily and said, "It's amazing, but it's also scary."
