The end of the TV series "Secret Service" is that the vagrant successfully entered the headquarters of the Secret Service and successfully obtained the evidence that Zhe also sent user information to the Secret Service. Huang Zicheng realized his dream and joined the National Security Bureau.

Huang Zicheng, restless and wandering, has been stalking and protecting her. Zhou Zhe found that Huang Zicheng was following, so he ordered the vagabond to kill Huang Zicheng. In desperation, wandering can only shoot Huang Zicheng. In the end, Yaoyao returned to the night fog with the research samples. In the eyes of Mr. Yu, wandering has become a firm night fog agent.

On the other hand, the spy "Dr. Bian" hidden in the institute has been exposed and arrested by Guoan. Dr. Bian realized that he had long been targeted by Guoan, and the samples and research materials stolen by the night fog had long been replaced by Guoan. Gao Tianyang expected that Night Fog would ask Dr. Bian to reconfirm the authenticity of the samples and research data, so he took out a USB flash drive and put it in front of Dr. Bian, asking Dr. Bian to send the research report on the USB flash drive to Night Fog to help the vagrant gain Mr. Yu's trust.

Huang Zicheng woke up in the hospital. It turned out that he had guessed that Mr. Yu would not fully trust vagrancy, and vagrancy would win Mr. Yu's trust with action. So Huang Zicheng put on a bulletproof vest, performed a wandering drama in front of the night fog, and identified himself as a wandering "absconding spy". A few months later, Wandering has successfully entered the headquarters of the Secret Service, and successfully obtained the evidence that Zhe also sent user information to the Secret Service. Huang Zicheng realized his dream and joined the National Security Bureau.

Introduction to the plot of "Secret Service Mission"

Scientific research samples of Jinhai Institute of Biology were stolen, and Gao Tianyang and Wu of the Reconnaissance Department of the National Security Bureau were ordered to take charge of the case. With the deepening of the investigation, an offline game called "Agent Mission" surfaced.

This game is based on pretending to be an agent to complete the task, attracting young people to join. In fact, it is controlled by the overseas spy organization "Night Fog", which uses offline tasks to lure players to spy. On the surface, Gao Tianyang's cousin Huang Zicheng is a master of games, but in fact he is an "informant" of the national security department lurking in the game.

Sure enough, the "Night Fog" organization targeted Huang Zicheng, sent a spy member to wander and approach, trying to drag him into the water. Huang Zicheng, with a pretence, continued to secretly provide information for Guoan. Gao Tianyang cooperated with Wu to find out Zhang Laoda, the leader of the spy organization hidden in Jinhai, and Lao K, the infiltrator hidden in the Institute of Biology. In this contest, Huang Zicheng fell in love with vagrants, successfully resisted vagrants, and we won the final victory.
