Zhang Yi, the reclusive medical and martial arts successor of Zhongnan Mountain, came down from the mountain to fulfill his childhood engagement with Wang Anan, but was misunderstood by the Wang family as a "country bumpkin son-in-law." He secretly guarded Wang Anan, and successively resolved crises such as the Zheng family's fraud, Li Yunxi's troubles, and Wan Peng's revenge, and helped the Wang family turn the corner many times. In the end, no longer hiding their identities, Zhao Chengguang of Chengguang Chamber of Commerce, Du Yunwei, the military leader, and Zhong Yaosheng, the richest man in Tianhai, all showed up to show their respects. Zhang Yi and Wang Anan joined hands to take charge of the Wang Family Group, opening a new chapter.
