Chang'an after the An-Shi Rebellion was peaceful on the surface, but in reality there was an undercurrent. Zhu Lie, a young man who is regarded as a "stupid thief", has "insights" that tear through the fog of history - he can see the true logic behind historical events, but he cannot directly change the facts that have happened. In an accident, he became a pawn in the power game between Concubine Taizhen (the prototype of Yang Yuhuan) and the powerful eunuch Li Fuguo, and was framed for stealing the fragments of "The Meeting of the Tang Dynasty". Everyone thought that this "wolf dog"-like street gangster was bound to die, but they didn't know that he had already seen through the truth and lies. Zhu Lie used his "golden finger" to fight back in a deadlock. Not only did he reveal the shocking secrets in the fragments, but he also discovered that there was a deeper force hidden behind Concubine Taizhen and Li Fuguo - a "bookstore" organization that holds the truth of history. Just when Zhu Lie thought he could stay out of the matter, he was involved in a thousand-year chess game related to the fate of the Tang Dynasty. He wants to find an opportunity for a comeback in the gaps between historical facts, and every step may be a dance on the edge of a cliff.
