Xiao Jin, the tyrant of the Yan Dynasty, had been debauched and immoral for three years after he came to the throne. Everyone in the court was in danger, and everyone thought that he was just a piece of trash left behind by the late emperor. Only Shen Qingzhou, the bodyguard who died, knew that the man on the dragon chair had poison-tempered blades hidden in his eyes - he pretended to be crazy in order to hide in the surroundings of powerful officials; he acted stupid in order to lure out the wolves in the dark.
Shen Qingzhou is a killing machine trained by Xiao Jin himself. He is cold-blooded, silent, and only knows how to execute orders. He thought he was the monarch's sword, until one night he discovered that Xiao Jin was drawing a border defense map in a secret room. His fingertips were stained with blood but he was laughing like crazy: "Qingzhou, how long do you think I can continue to perform this play?"
In the court, Xiao Jin pretends to be a pig and eats the tiger, playing with the treacherous officials; deep in the palace, Shen Qingzhou protects him with his life, but he does not know that he has become the tyrant's only weakness. When the "bastard" tyrant shows his fangs, when the "tool" dead soldier shows his selfishness, in this two-way disguise and redemption, whoever tears off the mask first will be doomed.
Purpose: To find light in the darkest plots, to break through disguises with sincerity, and to overcome the abyss with redemption.
