In the 30th year of Wanli, "Records of the Ming Dynasty" suddenly began to rewrite itself. When a history book adds a new entry, reality becomes a part of the past; when a history book deletes an official, that person gradually disappears from archives, memories, and traces of the world. When Shen Yanqiu, the secretary of the Department of History, was sorting out old files, he discovered that the colleague he was talking to yesterday had become "a person who never existed" today. In order to preserve the true history, he was forced to be involved in a conspiracy surrounding history books, government affairs and destiny. But as he searched deeper and deeper, he realized that the so-called compilation of history was never about recording the past, but about deciding who was qualified to live in the Ming Dynasty.
