Yan Ping suspected that Mr. Zhang was related to a certain video, but Mr. Zhang denied it. Yan Ping threatened Grandpa Zhang not to speak out about this matter. After returning home, Yan Ping felt confused about the source and purpose of the video, fearing that his criminal evidence would be leaked.

Yan Ping received a ransom email asking him to come to Teacher Zuo's house at 11 o'clock, implying that the other party may be doing it for money. Yan Ping replied by asking if the other party needed money, and the other party replied that he would understand at Teacher Zuo's house. Yan Ping received a new video and recalled his past with Teacher Zuo, deciding to take action again. Late at night, Yan Ping sneaked into Teacher Zuo's house, hid his bag, and waited. At eleven o'clock, Sinan's father appeared and was subdued and tied up by Yan Ping. Yan Ping demanded the whereabouts of the video and threatened to kill his entire family. Sinan's father revealed that Teacher Zuo has been killed by Yan Ping. Yan Ping was filled with pride and prepared to kill someone to silence him. Suddenly, Teacher Zuo appeared and Yan Ping fainted in fear. Qi Xia, Tang Chengcheng, Si Nan, and Zheng Xiaohu appeared, realizing that this was a trap they had set up and successfully recorded Yan Ping's confession. Qixia suggested calling the police immediately.
