A mountain youth, Gu Ye, entrusted by his master, goes down the mountain to deliver an item. On the way, he accidentally saves Ye Xiaokui, the cousin of the Su family, and by a fluke rushes into the Su family's martial arts ring for recruiting a son-in-law, defeating Su Yanning, the president of Haiyue Power. The two originally do not approve of this accidental marriage, but generate a bond due to an engagement set by elders in their early years. External forces covet the precious technology core kept by the Su family, and successively use means such as commercial blockade and malicious obstruction to suppress the Haiyue Group. At a critical moment, Gu Ye steps forward and, with his own ability and the assistance of several senior martial sisters and brothers, resolves the enterprise crisis time and time again.
