Chen Hongzhi returned home with the mission of serving the motherland's intelligence cause. On the ship, he bravely fought against the Japanese ronin who bullied his compatriots, and met the like-minded Su Wanqing. After returning to China, he used family resources to form an intelligence team, recruited Zhang Meng and other members, and conducted intelligence skills training. The team experienced challenges such as the first confrontation, going deep into the tiger's den to steal evidence of the enemy's slander against the Nine Domains, and dealing with internal interference and numerous traps. Finally, the team successfully released the evidence and thwarted the enemy's conspiracy, and then continued to start a new journey for the national intelligence career.
