Episode 17 recap: Pei Laosì threatens Sha Xiaofei.

Pei Laosì took out a syringe. Sha Xiaofei said he has already told Pei Laosì everything he knows. Pei Laosì said if that's the case, Sha Xiaofei is of no use to him. Pei Laosì gave the syringe to Chu Yihan, saying that if he doesn't inject it into Sha Xiaofei today, he will inject it into his mother.

Pei Laosì brought Chu Yihan over. The people on this side said their boss mentioned that they should meet Chu Yihan first. Gu Linna, the elder sister, took out her husband's photo, saying that he had prepared it a long time ago. Gu Linna told Gu Lina that their uncle had an accident. He received a phone call and left as soon as he was called "old accountant", and they haven't been able to reach him since.

Gu Linna called A Ku and asked if he knew who the other party was. A Ku said the other party is Pei Laosì. Gu Linna asked him for help in rescuing her uncle and her friend. A Ku said it would be more convenient for Gu Linna to do this herself and suggested she use the computer in her brother-in-law's office.

Pei Laosì received a call from Gu Mulan, which surprised him. Gu Mulan told him to keep Chu Yihan, or else there's nothing to talk about. Pei Laosì proposed a meeting, and Gu Mulan said she would inform him of a suitable time. In fact, it was Gu Linna who made the call using Gu Mulan's voice.

Sha Xiaofei was brought over, and Pei Laosì asked if he knew if the location of the pentagram was the Buddhist hall. Sha Xiaofei said he really didn't know. Pei Laosì took out a syringe containing drugs. Sha Xiaofei said he has already told Pei Laosì everything he knows. Pei Laosì said if that's the case, Sha Xiaofei is of no use to him.

Pei Laosì gave the syringe to Chu Yihan, saying that today, if he doesn't inject it into Sha Xiaofei, he will inject it into his mother. Sha Xiaofei and they engaged in a fight, and Chu Yihan also helped. Sha Xiaofei killed two people on their side and took control of Pei Laosì, saying that he wants to see Yi Yi.

Pei Laosì said Yi Yi is in a private hospital. Sha Xiaofei told him not to say too much and that he must see her. Chu Yihan asked Sha Xiaofei to put down the gun first, and Pei Laosì agreed to take him to see the person.

Jordan noticed that Chu Yihan's signal was lost and reported it to Director Tai. Director Tai instructed Duan Qing to take a team and investigate the location where the signal disappeared.

Duan Qing and the team arrived at the location but found no one there. They discovered a mark left by Chu Yihan on the corner of a table, with the last stroke unfinished. Duan Qing took a photo of the mark, and Cheng Fan realized that it meant a request for assistance in a state of losing control. Pei Laosì received a call, arranging a meeting for now.

Pei Laosì brought Chu Yihan over. The people on this side insisted that their boss wanted to meet Chu Yihan first. When Chu Yihan entered, he was surprised to see Gu Linna and told her to leave quickly. Gu Linna asked if he was looking for the mark left by his mother and offered her help, asking him to come with her.

Chu Yihan said he couldn't leave at the moment, but to his surprise, Gu Linna had prepared a motorcycle. Pei Laosì sensed something was wrong and sent someone to investigate. Unexpectedly, Chu Yihan rode the motorcycle with Gu Linna and rushed out. Pei Laosì quickly ordered his men to chase after them.

Gu Linna handed Chu Yihan a hunting rifle, and Chu Yihan fired, blowing out the tires of the pursuing cars, making them unable to catch up. Jin Shu brought Sha Xiaofei to meet Yi Yi. Jin Shu directly killed the driver and asked Sha Xiaofei where the warehouse was. Jin Shu mentioned that he used to have many brothers, but they were gone, and he now followed Lao Qiang. The warehouse was there, and he wanted it for himself as well.

Sha Xiaofei agreed to disclose the location to him. He arrived and met Yi Yi. While they were hugging, Yi Yi secretly handed a gun to Sha Xiaofei. When the others arrived, they found that Sha Xiao Fei and Yi Yi were gone, and Jin Shu was already dead.

Gu Linna asked Chu Yihan to go somewhere with her. Chu Yihan asked where they were going, and Gu Linna said he would find out when they arrived, emphasizing that Chu Yihan should not contact his superiors at the moment.
