Modern young man Yue Yuntian touches the fragment of Liquan Sword and accidentally travels to Shaoxing in the Southern Song Dynasty for ten years, which coincides with the Yue family's army's great victory in Licheng and the impending crisis of Fengbo Pavilion. Carrying historical memories, he infiltrated the Yue Family Army incognito and gained Yue Fei's trust with his modern wisdom. However, because he could not speak out the outcome, he could only struggle between "protecting Yue" and "avoiding disaster." When twelve gold medals come one after another, and when Qin Hui's black hand reaches out quietly, can he rewrite the tragedy of his ancestors?
