Former top combat force of the Z Group, Wang Yan, was set up by the organization and fled back to Linjiang to live under an alias as a security guard. By chance, he had a romantic encounter with Jiang Xinrou, the president of Xinghai Group, and upon taking the job, he became embroiled in the Su family's internal power struggle. Relying on his superior skills and wisdom, he bravely blocked attacks, thwarted opponents' conspiracies, defused gang assassinations, and navigated business games. While keeping a low profile and surviving, he guarded Jiang Xinrou and the Su family siblings, stirring up the business and underworld circles of Linjiang.
