Li Yunji, Emperor Jinghe, was born as a puppet emperor for nineteen years. On the surface, he was obsessed with painting and did not care about government affairs, but secretly he laid a dragnet. Until two female assassins broke into the Forbidden Palace at night and pierced his disguise with a sword - a crack was opened in the dilemma where the whole court was surrounded by enemies. Powerful ministers, eunuchs, harems, and vassal kings, the four forces are intertwined like a spider web. What he wants to do is to burn the net before it bites his throat.
