Su Qinghe

Traveling through five generations of troubled times, he pretended to be someone else, but was involved in an identity mystery that spanned a thousand years. Lin Yan, a researcher on modern Song history, accidentally fell into Bianjing seven years after Zhou Xiande. In order to survive in troubled times, he assumed the identity of a descendant of the late Cui family of Qinghe, relied on historical knowledge to predict the current situation, and dealt with the nobles and political conspirators in the name of "Cui Mingyan". However, the risk of risking one's surname is far beyond imagination - the reconstruction of the old genealogy, the strict inspection of household registration in the new dynasty, the temptation of mysterious scholars, and the ancestral token paired with Lu Duan's jade all point to a carefully woven trap. When the flames of the Chenqiao mutiny reach Bianjing, he must reveal his destiny in the torrent of history: Will he become a chess piece of a famous family, or will he break the chess game and find the truth behind the true and false surnames that traveled through time and space?
