The current emperor, who is crazy and tyrannical, claims to be the orthodoxy of the previous dynasty, but due to a bloody night chaos, he became insane and mistook the cold-faced general Pei Lin for the orphan of the previous dynasty who was left behind among the people. Pei Lin had a blood feud, but he pretended to be submissive, used the help of the mad emperor to eradicate powerful officials, and secretly plotted to restore the country. The two are entangled step by step in the turbulent atmosphere of the court. One uses madness as a blade, and the other uses tolerance as a shield. Under the confusion of real and fake orphans, there is a bloody game of imperial power, memory and destiny. Only each other is the only real existence in this troubled world.
