After testing, the bloodstains found in Zhen Zhen's house were not human blood, and the bloodstains that she accidentally dripped on the floor when she killed chickens some time ago.

Through investigation, it was found that Zhen Zhen and Zhang Qianyuan could only trade money, and there were not too many disputes, and her suspicion was temporarily ruled out.

Just when the case was at a loss, the results of Zhang Qianyuan's further incident came out.

After an autopsy, the medical examiner found poisons in his stomach capacity and had taken a large amount of sleeping pills during his lifetime.

This would explain why the physically strong Zhang Qianyuan would be hurt without resistance.

Jiang Yanxuan and the others investigated and found several people who had taken drugs with Zhang Qianyuan before.

They all said that they had not seen Zhang Qianyuan on the night of the crime.

Since Zhang Qianyuan didn't take drugs with them, where was he drugged?

Zhang Qianyuan and his wife Huang Yueye were originally junior high school classmates. After graduating from secondary school, Huang Yueye and Zhang Qianyuan joined hands and entered the palace of marriage together.

At that time, the two of them were very poor, but fortunately, Zhang Qianyuan was very self-motivated and very thoughtful and motivated, he wanted to buy a car, he wanted to do some projects, and for this reason, he also sold the motorcycle he bought when he got married.

In order to earn more money, after the work of buying in the morning, Zhang Qianyuan had to drive a truck to transport earthwork, and only rest for four or five hours a day, in order to create a good living condition for his wife.

But as the living conditions gradually improved, Zhang Qianyuan actually learned to take drugs/protect his lover and other vices.

Huang Yueye had already been aware of Zhang Qianyuan's lover.

There are also frequent arguments between the two over this matter.

Zhang Qianyuan often doesn't go home, sometimes when he comes back, he just sits at home for a while, and sometimes he leaves without finishing his meal.

Huang Yueye They also have a dog at home, and they usually spend more time watching the dog than looking at her, and the relationship between the two people slowly became separated.

Jiang Yanxuan's suspicion of Huang Yueye immediately rose, and they obviously knew something about Zhang Qianyuan's drug use and lover, why did they say that they didn't know anything when the police asked about it?

Moreover, Huang Yueye said during the initial interrogation that Zhang Qianyuan was going to F County that night, but in fact, according to Jiang Yanxuan's investigation, Zhang Qianyuan frequently drove in the urban area of S City that night.

Why didn't he go out of town? There have also been disputes and conflicts between the two of them because of their feelings. So at this time, Jiang Yanxuan and the others shifted their focus to Huang Yueye.

Just when they were conducting a key investigation on Zhang Qianyuan's wife, Huang Yueye, Lin Hui's responsible group, which was responsible for finding Zhang Qianyuan's trajectory on the day of his death, got a piece of news.

That is, at two o'clock in the morning, Zhang Qianyuan's Honda sedan appeared again in the city, and also went to a gas station to refuel, at this time the license plate number has become three six**.

At two o'clock in the morning, according to the results of the medical examiner's autopsy, he should have been dead by then. In the footage captured by the surveillance, his license plate has also been changed to 666.

And there was a man and a woman sitting in the car, and there was a high probability that the two of them forged license plates.

Because so much time had passed, the people at the gas station could no longer recall the physical characteristics of those two people.

What's more, the surveillance camera at the gas station happened to malfunction that day, and it was not able to capture this picture.

If Huang Yueye is the murderer, then she should be the woman who appeared at the gas station in the middle of the night.

In that case, could that man be the murderer she hired?

Could there be such a possibility?

Huang Yueye became more and more impatient with her husband because of his various malice and attitude towards her.

After thinking about it, he decided to kill the killer and called an accomplice.

Zhang Qianyuan, who went out to work with Gao Chen that night, did not plan to go home after finishing work, but went to Zhen Zhen's house, but then his drug/addiction attacked, so he left and returned home.

After taking drugs/products, Zhang Qianyuan's brain was groggy and unconscious, Huang Yueye knew that her opportunity had come, so she gave Zhang Qianyuan a large dose of sleeping pills to make him fall into a deep sleep, and then strangled him to death.

After the incident, Huang Yueye called for helpers, planning to destroy the corpse.

She originally wanted to buy gasoline and burn the body along with the car, but she probably didn't buy it, so in a panic, she had to find a remote neighborhood nearby and dump the body there.

Subsequently, in the police's questioning, he falsely claimed that Zhang Qianyuan had gone to work in other places to divert the police's attention.

If this is the case, it can be explained why Zhang Qianyuan did not go to other places on the 4th and frequently appeared in the urban area.

In the face of Jiang Yanxuan's inquiry, Huang Yueye confessed that from the time she learned about Zhang Qianyuan's death, she probably guessed that it was very likely to be related to drug use/custody/raising a lover. But he was afraid that he would be implicated because of his vices, so she lied, but Zhang Qianyuan's death had nothing to do with herself.

Later, Jiang Yanxuan and the others also confirmed through their visits that Huang Yueye went back to her parents' house on the night of the crime, and then stayed at home until the next day, so it can be said that she did not have time to commit the crime.

Neighbors also confirmed that Zhang Qianyuan did not return home that night, so the above conjecture is not valid.

The clue was interrupted again, and the person who could kill Zhang Qianyuan so easily must be someone who was very familiar with him.

So why can't Jiang Yanxuan always find this person and get no valuable clues? Could it be something that went wrong in the previous investigation?

In the past few years of work, Jiang Yanxuan has become accustomed to combing the case with Lu Guan at dinner every night, and every time he analyzes and comes back to his senses, he finds that the food is already cold.

It can be said that whether it is in work or life, Lu Guan and him are a perfect match, a natural pair.

No matter who he replaced, no one could review his work with Jiang Yanxuan during dinner, and could give him many inspirations and different ideas.

Lu Guan knew very well what Jiang Yanxuan wanted, the longer the two of them got along, the more inseparable they were.

If one of them wants to pull the other person out of his heart one day, it must be cramped and bone-splitting, and finally he will die of heartache.

Lu Wan suddenly remembered the street in front of his school gate full of stalls.

On that street, there was a blind couple who got up early and sold rat poison at night.

In order to expand the scope, the two of them set up a booth more than ten meters apart. At that time, they each held two small bamboo planks in their hands. Every now and then there is a crisp sound.

At first, Lu Guan thought it was their method of soliciting customers. Later, it was thought that they were informants of some secret organization, using Morse code.

One afternoon, Lu Wan walked down the street and happened to pass by her blind husband, when the bamboo board in his hand rang out; Immediately afterwards, the bamboo board in his wife's hand more than ten meters away also sounded. Then the bamboo board in her husband's hand changed its rhythm and started again.

And so on and so on several times.

At this time, Lu Wan saw a happy smile on the faces of his blind husband and his wife in the distance.

That smile was warm, contented, and melted into the sunset, in the evening breeze.

Seeing that smile, he realized that this was not a solicitation of business, nor was it a Morse code.

They may never know how blue the sky above them is, or how beautiful the flowers are sold. But they know that they are still with each other and have never gone far; They don't see each other's faces like many couples, but many couples can't see each other's hearts like they do.

The darkness and pale life in their eyes have changed from black and white to colorful because of each other's warmth.

Lu Guan often feels that he is the luckiest person in the world, and in fact, he is exactly that.

After solving so many cases of emotional disputes, he felt more and more that he and Jiang Yanxuan could see each other, and how precious and rare it was to be able to see each other's hearts.

He Lu Guan must have done a lot of good things in his last life, so he can be so lucky in this life.
