Seven years ago, Xiao Beichen, the greatest martial god of Great Xia, suffered the horrific massacre of his entire family. Believing his wife and daughter had perished in the flames, he concealed his identity and settled in Dragon-Hidden Fishing Village, making a living selling fish at the docks. When the ruthless Zhao Tianba joins forces with Erhu to seize the village's land, the villagers suffer one attack after another. To repay Mei Ruoyuan for saving his life, Xiao Beichen is forced to fight back, defeating Erhu with a single punch and crippling Zhao Tianba's martial arts. After the battle, Xiao Beichen unexpectedly discovers that Xiaoyu, a young girl who has been kidnapped, is wearing his family's ancestral jade pendant. He realizes that Xiaoyu is actually his surviving daughter, Xiaoxiao. Following clues from an iron token belonging to the Swallow Sect, he breaks into an underground fight club to investigate the mastermind, Yan Qing. Just as Yan Qing is about to reveal the truth, someone silences him, leaving behind only one clue: the character 'Qin'.
