"Is it because of Liu Qin's matter that our police asked you to cooperate with the investigation, which put you under pressure?"

Han Feilu was not just talking, he really cared about Zhou Song and began to analyze the reasons for him.

Zhou Song was indeed stressed, but not because of Liu Qin, but because of the box of watercolor brushes and other items sent to his home. He was worried that he had quietly split into two people without his knowledge. After seeing a psychiatrist

Before, he had been worried about this matter. After seeing the psychiatrist, it was better not to see him. But at this time, Han Feilu seemed to have taken over the role of the psychiatrist. Although his words were rough and he was not very patient, he was sincere.

, so it felt good to have a heart-to-heart talk with him.

Zhou Song smiled and said, "If I say yes, will you stop bothering me about Liu Qin?"

Han Feilu told the truth: "No. I will keep annoying you until this case is over."

There were not many people in the square. There were green trees everywhere, and the breeze was blowing, making it cool and pleasant. Zhou Song said: "Let's take a walk."

The two of them walked slowly along the lawn. Zhou Song asked, "So you are looking for me this time because of Liu Qin's case?"

Han Feilu raised his hand and broke off a wicker stick, holding it in his hand and playing with it: "For Liu Qin, and for Pan Shaojie."

Zhou Song: "What's wrong with Pan Shaojie?"

Han Feilu: "I suspect that he has something to do with Cai Minmin's death. He has a man named Feng Danian, do you know him?"

Zhou Song: "Although I am relatively close to him, I don't know any of his friends."

Han Feilu: "He was not his friend, but the nightclub lobby manager. On the day Cai Minmin died, he was the one who sent Cai Minmin home. Although Cai Minmin was alive at the time, she died the next day. We found several grams of methamphetamine in Cai Minmin's house, and Cai Minmin died again.

He died of an overdose of drug injection, so we thought Cai Minmin's death was an accident at the time. Until yesterday, I found out the source of the drugs. The few grams of methamphetamine in Cai Minmin's home were in the hands of a dealer named Xiong Liang. Xiong Liang confessed that he was on May 14

At about 11 o'clock in the evening, I went to the back door of Heaven and Earth to deliver goods to Feng Danian. But the next day, the goods appeared at Cai Minmin's house."

Zhou Song: "Do you now suspect that Cai Minmin died in a trap? Did Feng Danian deliberately instigate Cai Minmin to take drugs, causing her to be poisoned and died?" He shook his head, "This plan is not very practical. Even if Feng Danian really intended to kill her with this plan

Cai Minmin, how can he guarantee that Cai Minmin will voluntarily inject an overdose of methamphetamine? You just said that Cai Minmin died the next day. She was the only one at home at that time. Could it be that Feng Danian had a way to control her actions remotely? "

Han Feilu wrapped the wicker around his hand: "This is the suspicion. Last night we went to find Feng Danian. He has disappeared. His disappearance just proves that there is suspicion on him. I suspect that the murderer of Cai Minmin is

He, but I don’t know what method he used. Even if Cai Minmin is addicted to drugs, it is unlikely that she would inject herself with methamphetamine when she got up in the morning or was hungover the night before. And she should know very well how much she can bear.

There is no reason why Feng Danian would make a mistake to the point of killing herself. Is Feng Danian just waiting for her to make a mistake? Then the uncertainty of this plan is too great."

Zhou Song frowned, thoughtfully. He pushed aside the wicker on his shoulder and walked for a while before saying, "You always said that Cai Minmin died from an overdose of drug injection. She didn't inhale it, but injected it with a needle, right?"

Han Feilu: "Yes."

Zhou Song: "When you found the body, how many syringes were there?"

Han Feilu: "About a dozen, seven or eight have been used, and there are still a few that have not been opened."

Walking out of the path, we arrived at a fan-shaped square. There was a sculpture in the middle and a vending machine beside it. Zhou Song said: "Wait for me here." After that, he walked towards the vending machine and scanned the code to buy.

He bought two bottles of ice-cold green plum green tea. He walked back with the drink and saw Han Feilu looking at the sculpture in the center of the square; it was an irregularly shaped sculpture made up of several elliptical rings nested together.

Each ring is painted with different colors of paint. However, over the years, wind and rain have corroded the paint, and the paint has peeled off badly, revealing their original appearance of gray-brown.

He handed a bottle of drink to Han Feilu and said with a smile, "This is an apology."

Han Feilu deliberately turned his back to the statue and caught the drink: "You can make up for the trauma in my heart by giving me Yunnan Baiyao."

Zhou Song's eyes passed over the statue lightly, took a sip of water, and asked: "Have you performed an autopsy on Cai Minmin?"

Han Feilu: "It only started yesterday. Because no traces of criminal offenses were found at the scene, Cai Minmin's parents did not agree to the autopsy. Only yesterday after Xiong Liang was discovered, Cai Minmin's family agreed to the autopsy. But it was delayed for several days."

Zhou Song: "Have you checked her medical records and medical records?"

Han Feilu: "After checking, I found that she had been in Yucheng for a year, and she only stayed in the hospital for two days three months ago due to acute enteritis. Other minor illnesses and pains may have been solved by buying medicine on her own or going to a private clinic."

This situation is very common. Many foreigners who come to work in big cities avoid going to the hospital all year round in order to save money. If they have any pain, they have to take medicine by themselves or go to cheaper small clinics. Therefore, it is difficult to find their medical records.

Zhou Song took a few steps back and stood in the cool shade. Han Feilu followed him and said, "You ask in such detail because you want to help me analyze it?"

Zhou Song put the water bottle around his neck to cool himself down: "I have an immature guess, but there is no evidence to support it."

Han Feilu: "Tell me about it, I won't blame you if you guess wrong."

Zhou Song then said: "My thoughts are the same as yours. I also think it is unlikely that Cai Minmin will make a mistake himself, and it is even less likely that Feng Danian and others will make a mistake. If Feng Danian is really the murderer, then he must have a complete plan.

Make sure Cai Minmin can die in her own hands."

Han Feilu: "What's the plan?"

Zhou Song: "It is undisputed that Cai Minmin injected the drugs herself. But is it possible that Cai Minmin did not know that the syringe contained drugs, but regarded it as something...

..drug?"

Han Feilu has a bright mind and is very good at drawing inferences: "You are saying that Cai Minmin may be suffering from a certain disease that requires her to inject certain drugs regularly and quantitatively. On the morning of the incident, she injected herself with drugs as before, but after

He injected drugs without his knowledge."

Zhou Song nodded: "This plan is easy to implement. She only needs to replace the medicine she prepared with drugs in advance. If she has the habit of putting the medicine into the syringe in advance, then she only needs to change the syringe. There are many diseases that require long-term treatment.

Injection drugs, such as gynecological inflammation or diabetes. Considering that you have not issued an autopsy report and cannot find her detailed case, I suggest you check her consumption records and ask her friends around her. She may

She has purchased certain medicines herself, or asked a friend to help her purchase certain medicines."

Han Feilu had the words "No thanks" written on his face. He patted his shoulder hard and walked a few steps away to make a phone call. After arranging his work, he walked back and found that Zhou Song was no longer under the shade of the tree.

, standing next to the sculpture in the center of the square.

He walked up to Zhou Song, looked at the sculpture, and said, "It was only when I saw this sculpture that I remembered that this was the place where Wei Chunhong's body was buried."

Ten years ago, this square was still a construction site and the scene of the Wei Chunhong case. The sculpture faces 1.3 meters west, which is where the police exhumed Wei Chunhong's body.

Zhou Song touched the sculpture, and the cracked patent leather on the surface fell off. He wiped off the dust on his palm and walked slowly around the sculpture: "When was this built?"

Han Feilu stood still and said, "I don't remember the exact time clearly. It should be around September 20, 2012."

On September 20, 2012, five days after Wei Chunhong's body was discovered, this sculpture was erected and stands today.

Zhou Song walked around the sculpture and returned to Han Feilu: "You just said that you are looking for me not only for Pan Shaojie, but also for Liu Qin. We have finished talking about Pan Shaojie, now let's talk about Liu Qin."

Han Feilu: "Let's bring up the old story again. Liu Qin came to see you on the night of the 14th. What did he say to you?"

Zhou Song: "Is it important?"

Han Feilu: "Of course it's important. He hasn't contacted Lan Lan for many years, but he went to see Lan Lan after meeting you, and still sneaked into Lan Lan's house secretly. Don't you think it's strange?"

When he asked, Zhou Song felt strange. He thought about it carefully and said, "That night he came to me with a box of pens."

Han Feilu: "What pen?"

Zhou Song looked towards the highway: "Are you driving?"

Han Feilu: "Stop at the intersection."

Zhou Song said: "Let's go to Lan Lan's house and have a look. If we're lucky, we can still find the box of pens."

On the way, Zhou Song explained the origin of the box of pens in detail: "Wei Chunhong is the head teacher of our class. She teaches English. In addition to our class, she also teaches Classes 5 and 13. One day she bought a box of pens and got

The class said it would be a reward for students who can get 90 points or above in the English test next month. There are 10 pens in the box. She uses 1 for herself, and there are 9 pens left. They will be distributed until supplies last. The monthly test is over.

A total of 7 students in the three classes scored over 90 points, including me and Lan Lan. Excluding the one she used, there should only be 2 left in the box. But Liu Qin accidentally found it at home a few days ago

He picked up the box of pens and came to me with the pens, but there were still three pens in the box."

Han Feilu didn't see what Zhou Song said in the case file: "One of them belongs to Wei Chunhong?"

Zhou Song shook his head: "No, Wei Chunhong is used to carrying pens in her bag, but when the police and Wei Chunhong's family checked the belongings in the bag, they did not find the pen. At that time, everyone thought it was a trivial matter, and Wei Chunhong might not

Carefully, he lost the pen, maybe somewhere in the office or at home. It wasn't until 10 years later that Liu Qin found the box of pens and found that there were three more pens in it, one of which was used and filled with blue ink.

If Wei Chunhong uses it herself, she will use red ink. I often go to her office and she only uses red ink."

Han Feilu: "A used pen, was it given to students by her and then taken back?"

Zhou Song: "This explanation is the most convincing. But -"

He hesitated to speak, his face serious. Han Feilu looked at him: "But what?"

Zhou Song: "When Liu Qin discovered that Wei Chunhong's pen was missing, he suspected that I was the murderer. Naturally, he also suspected that I had taken the pen. He searched my schoolbag at the police station and found the same pen as Wei Chunhong's. He

He thought he had caught the murderer, but he didn't know that the pen was the prize I got, and there were 6 other people besides me. He didn't believe it, so I took him back to school and called all the people who got the pen, in front of him.

He didn't give up until he took out the pen he got in front of him. But when everyone took out their pens, he found a used pen in the pen box, and it was the pen that Wei Chunhong had sent out and taken back. Explanation -

—”

He suddenly felt that the air conditioning in the car was too strong and his skin felt cold, so he went to adjust the button that controlled the air conditioning.

Han Feilu continued what he had not finished: "It means that one of the pens you took out back then did belong to Wei Chunhong. The murderer was among the students back then."

Perhaps it was because Zhou Song was not familiar with Han Feilu's car. After twisting it for a long time, the air conditioning in the car only increased. His face seemed to be frozen by the cold air and was as white as a layer of frost. Han Feilu

He pushed his hand away, turned the knob twice, and turned off the wheezing air-conditioning.

Zhou Song breathed a sigh of relief and said, "It was because Liu Qin thought of this that he came to me and wanted me to take out my pen and let him identify it to see if it was Wei Chunhong's."

Han Feilu: "Did you show it to him?"

Although it was clear that Han Feilu was not targeting him personally, but was just conducting an impartial law enforcement investigation, Zhou Song still resisted being questioned by him in an interrogative tone. "No, I don't know where I threw him."

Han Feilu took care of his emotions and stopped asking questions: "After looking for you, he went to find Lan Lan. Maybe he wanted to confirm whether Lan Lan's pen was the one Wei Chunhong lost."

When they arrived at the downstairs of Lan Lan's house, Han Feilu parked the car by the corridor and went upstairs with Zhou Song. There were seals and warning lines posted at the door of Lan Lan's house, and there were two roadblocks. Han Feilu lifted the obstacles one by one.
