Xu Hai dragged his lame legs and hid back and forth in the alley late at night. When he ran to the corner, he was hit hard by a man in black. He fainted to the ground and was dragged away from the scene.
Wang Ya saw that he had failed, so he left alone, leaving Wen Xiang and the patrol room to explain. Wen Xiang was taken back to the patrol room, and he and Zheng Yifei reorganized the course of events, and basically concluded that the massacre of the Fang family was jointly caused by Xu Hai, clay figurine Xu and sugar figurine Chen.
Zheng Yifei urged Wen Xiang to use his sense of smell to dig deeper for clues. Wen Xiang suddenly thought that Xu Hai suffered from heart disease and carried holly holly with him. However, the smell of holly holly was not smelled at the practice site. There might be another possibility. At that time, The cripple who appeared at the scene was not Xu Hai.
In order to confirm his inference, Wen Xiang took Zheng Yifei back to Xu Hai's home and found that the clothes in the closet did not smell like holly. Wen Xiang vaguely guessed that maybe he was being led by others and that everything was caused by the real murderer behind the scenes. Xu Hai's residence was discovered from the doctor's medical records, and the doctor may be suspicious.
On the other side, Wang Ya also found clues from Xu Hai's residence. The statue of Zhong Kui in the room was broken. For those who believe in ghosts and gods, they would not be so cruel. Their guesses were completely consistent.
After a while, Wen Xiang led the patrol team to Xu Hai's residence, and based on some new clues, he guessed where the murderer was hiding.
It turned out that the person who knocked Xu Hai unconscious was actually Fang Tianbo, the young master of the Fang family who everyone thought was wiped out. He was lucky enough to survive when he witnessed his parents being killed. He was originally suffering from congenital heart disease and could only grow to eighteen years old, but he He has survived to this day with the belief of revenge, practicing medicine in Zhuangyuan Lane in ambush to look for opportunities. Two of the three enemies have been eliminated, and Xu Hai is about to die soon.
Wen Xiang led the patrol team to a temple. Fang Tianbo held Wen Xiang hostage from behind. Wang Ya arrived shortly afterwards and demanded that he be exchanged for hostages. Fang Tianbo suddenly became angry and expressed that he hated Wang Ya even more. If Wang Ya had tried harder, his parents' injustice case would have been cleared up long ago. The injustice has been redressed, but in recent years Wang Ya has become an alcoholic. Without any hope, he can only rely on himself.
Only then did Wen Xiang realize that the person opposite was Wang Ya. Zheng Yifei used a flashlight to forcefully flash Fang Tianbo's eyes. Wang Ya took the opportunity to push Fang Tianbo down and save Wen Xiang.
Fang Tianbo knew that he had only one way to die, and shouted angrily: The world is unfair, and he can only wash away his grievances with sin. Then was shot dead.
After the case was solved, Wang Ya was still depressed. Wen Xiang hoped that Wang Ya could cheer up and teach himself how to investigate cases so that he could find out the cause of his parents' death. After asking Zheng Yifei, he learned that their good brother Zhou Ningfeng died unjustly. Wang Ya could not find the murderer and felt ashamed of Zhou Ningfeng, so he fell into despair.
