Some things can only be slowly reflected after the fact that something is wrong. In the circumstances of the time, there were some details that anyone would have overlooked.

Zheng Kai is no exception! Zheng Kai, who came back to his senses, felt that it was better to kill Dong Warriors than the price, after all, Dong Warriors had a very close relationship with Zhiwang Technology, even if he lost the authority of the level 0 manager, maybe he could use some other permissions.

But the matter has come to this point, and it is impossible for Zheng Kai to go back and kill Dong Yu. Zheng Kai lay on the sofa and rested for a while, and then withdrew from the massage chair.

A new day. Zheng Kai got up from the massage chair, washed up and walked to the police station. Zheng Kai rushed to the police station, Su Qing and Su Lan were already dealing with things at the police station, and the police station during this time was mainly busy with the deaths of Zheng Hongyan and Yue Fang.

Especially Yue Fang. No matter how you check, you can't find the person who delivered the medicine to Yue Fang. This made the colleagues at the police station very helpless.

The police station was infiltrated and sent something to the suspect who was being detained, and no one in the entire police station found out about this series of processes, and only after checking the surveillance did he know.

Because of this incident, the General Administration called the director of the Northwest City Police Station over and scolded him several times. During this time, Su Lan was stationed at the police station in the northwest urban area.

There are no major cases to be busy with from the General Bureau, so they have been temporarily transferred here to assist in handling cases. After Zheng Kai said hello, he returned to his archive.

None of these things had much to do with him. Frankly speaking, Yue Fang's suicide has nothing to do with Zheng Kai. When Zheng Kai heard the news of Yue Fang's suicide, he was also confused.

Noon time. Su Qing came to the archives and brought Zheng Kai a not good news, that is, Lu Dafu was found, but the person died.

Lu Dafu, as the general person in charge of the Zhiwang Technology production factory, disappeared mysteriously after the factory caught fire, and many people suspected that Lu Dafu set fire and absconded for fear of crime, but there is no evidence.

A factory fire was also eventually defined as an accidental fire. Su Qing and Zheng Kai were the parties involved in the factory fire.

Therefore, Su Qing wanted to call Zheng Kai to go to the scene of Lu Dafu's death together. Zheng Kai naturally has no problem.

After the two had lunch, they rushed to the scene of Lu Dafu's death. To Zheng Kai's surprise, the place of Lu Dafu's death was not very far from the factory that caught fire, and standing at the highest point of this place, he could see the factory that had turned into ashes in the distance.

It is estimated that the distance from this place to the production plant is only about a kilometer. Zheng Kai looked around.

The next second. Zheng Kai looked in one direction in a daze. Seeing this, Su Qing followed Zheng Kai's line of sight and looked at it from afar, but he didn't know what Zheng Kai was looking at.

"What are you looking at?" Su Qing asked. Zheng Kai pointed to a location in the distance, and in the distance, you could see an abandoned site with only walls left, and the buildings inside had been bulldozed, leaving only the outer walls.

And this place made Zheng Kai feel very familiar. Zheng Kai frowned and asked, "Su Qing, has the old site of the puzzle kindergarten been completely demolished?" ”

"Nope." Su Qing shook his head.

"Since the last time a lot of corpses were dug up in the puzzle kindergarten, that area has been completely stopped, even if the case was later announced to be closed, telling the developer that the development can continue, but the place is still in a state of suspension, and it is winter, and the enthusiasm of the workers is not high, so it has been retained." Su Qing's eyesight was not as good as Zheng Kai's.

Zheng Kai was able to see the buildings far away, but for Su Qing, it was a little difficult. Zheng Kai glanced back at the factory a thousand meters away, and then looked at the outline of the kindergarten far away, the place where Lu Dafu died, and he could see the two places of the puzzle kindergarten and the production factory at the same time.

However, if you want to see the Puzzle Kindergarten, you need good eyesight. The place where Lu Dafu died was a very dilapidated house, this house was very dilapidated, and the roof was still laid with very old tiles, and it was covered with moss.

Zheng Kai put away his thoughts and followed Su Qing into the house. It was damp inside the room. There had been a heavy snowfall before.

And when the snow melts, the water penetrates the roof and trickles into the house. In the very center of the room, a group of colleagues are being protected, and Lu Dafu is tied to a tin bed, wearing only a pair of underwear.

There are a lot of infusion tubes inserted in Lu Dafu's body. These infusion tubes are connected to one infusion bag after another, and most of the liquid in the infusion bags has been dripped into thousands of drips, leaving only some residual liquid.

There are also infusion bags that contain blood. If nothing else, the blood should be after the liquid in the infusion bag is transfused, and the air pressure in the body is different from that in the infusion bag, so the blood in Lu Dafu's body is returned to the infusion bag.

"The infusion bag is still a tranquilizer." Su Qing explained. Zheng Kai didn't squeeze in, the space in the room was not large, squeezing in might ruin the scene, Zheng Kai just looked at the edge of the room for a while.

"There is no sign of a struggle." Zheng Kai said softly. Two possibilities. First, Lu Dafu died a long time ago, and these tranquilizers were only injected into his body after he died.

But this is very unlikely. Once a person dies, the blood in the body does not circulate, so the infusion cannot enter the person's body well.

Second, Lu Dafu died of tranquilizers. With such a complex scene arrangement, it is obviously impossible to be a suicide.

The murderer transported Lu Dafu here from other places, and then arranged everything while Lu Dafu was in a coma.

"The last time we saw Lu Dafu in the factory, he answered a phone call before leaving in a hurry, did you find his mobile phone here?" Zheng Kai asked curiously.

"Yes, but it's badly damaged, and my colleagues in the Forensics Department need to try to fix it, and if they can't, they may not be able to view his call history." Su Qing had long known that Zheng Kai would ask this, so the moment he found Lu Dafu's mobile phone, he contacted his colleagues in the forensic department to take it back and repair it.

Just look at the scene. Actually, I don't see much of it. Of course, there is also the fact that the murderer handled it very well and left no obvious clues.

When Lu Dafu disappeared and the factory caught fire, colleagues from the police station contacted Lu Dafu's family, but Lu Dafu's family said they didn't know anything, and Lu Dafu had not returned home for many days.

Lu's family was not shocked. Because, Lu Dafu often lives in the factory, and sometimes only goes home once a week.

In general, the clues are different. Now the only clue is tranquilizers. Lu Dafu is already the third person to die from tranquilizers, the first two being Watson and Yue Fang.
