In the bathroom, Wu Jia's body was covered with various new and old injuries, which looked like they had been abused.After he walked out of the bathroom, he met a neighbor's aunt, and they separated after a brief chat.However, the aunt did not know that the cat in her mouth would become Wu Jia's experiment and be thrown into the trash can after use.

One day, the criminal police team was shocked to learn that the murderer of the latest case was the son of the murderer thirteen years ago.Bureau Huo and Wei Zhengrong both believe that they need to investigate the suspect's relatives because the murderer is likely to be someone they have seen before.Lao Zhu recalled a young man he had met recently. At this time, Lu Xingzhi remembered Wu Jia, whom he had met before, so he took Wei Zhengrong to night school.

However, they did not find Wu Jia at the night school, but learned that An Ning was sent home by the police, although An Ning walked home by herself.However, Wu Jia found peace one step ahead of schedule.Wei Zhengrong told Yang Man to go home immediately and told An Ning not to open the door and go out.Yang Man realized that the matter was critical and rushed home to find that An Ning was missing.They found a message on the computer, which was a picture sent by someone else.When everyone was checking the content of the picture, Yang Zhe passed by and found this picture, explaining that it was a painting called “Paradise on Earth”, and the author was Hans Bredreau, whose English abbreviation was HB.This painting is divided into three parts, namely heaven, earth and hell.It was discovered that female victims in several cases appeared in this painting at the crime scene.Seeing the name of the author of the painting, everyone thought that the murderer should be Wu Jia.They immediately went to the night school to search for Wu Jia and found him through surveillance.Wei Zhengrong carefully observed Wu Jia's photos, and suddenly remembered the looks of Zhang Sicheng and Zhang Shanshan when they were young, and discovered that Wu Jia was Zhang Shanshan.It turns out that the murderer has been observing the occurrence of these cases from a distance.

Wei Zhengrong's words shocked everyone present. When they found Zhang Shanshan's photo, they confirmed that the pseudonym Wu Jia was Zhang Shanshan.Then we began to investigate Zhang Sicheng. He worked at the Urban Construction Design Institute from 1988 to 2008. He retired due to cancer in 2008, but his address is unknown.Hearing that Zhang Sicheng worked as a surveyor, Lao Du recalled that the last time he visited, an elder sister said that she had seen someone walking around with a stick, as if doing some surveying.After finding the eldest sister, they learned where Wu Jia lived and pulled a big box away. So everyone immediately started searching. The building was empty, but a lot of evidence and investigation reports on some cases were found.

After returning to the police force, Lu Xingzhi learned that Qi Shasha had been rescued and provided Wu Jia's company and current job. He worked for a broadband company. A van in the company was also driven away by the other party. The surveillance also found the van and saw him.It was peaceful in the car..The technology department cracked the password of An Ning's QQ account. After logging in, he opened the recent contacts and found that the other party mentioned that he was going to a tower to find a paradise.Lu Xingzhi seemed to know that it was the River View Tower, so he immediately led the team there.

On the way, Lu Xingzhi thought that a murderer like Zhang Sicheng might have had the desire to commit murder in his heart for many years before he took action. Then something suddenly stimulated him. The painting might be an inducement, which fit the bill.He understood the dark image in his heart and speculated that when Zhang Sicheng killed Mo Lan, he might have subconsciously covered the other person's face because he didn't know who to kill. However, when he killed Liu Meng and Du Mei, it showed that he had already determined his direction..

When they arrived at the Guanjiang Tower, everyone started to work in teams. There was nothing on the top of the tower. Wei Zhengrong accidentally found a piece of rosin, and Lu Xingzhi recognized it as something from An Ning.Then the two opened the map and speculated on the location where Wu Jia might return.
