Zhou Yu'an, the seventh prince of Zhou Dynasty, has been frail and sickly since childhood. He is an inconspicuous existence in the palace and can be bullied by everyone. After a high fever, he unexpectedly acquired a strange ability - he could see the "malice" emanating from others. The usually kind palace maids, the kind royal brother, the loving concubines... In Zhou Yu'an's eyes, they were all wrapped in thick or light black mist. This splendid prison turned out to be full of wolves who wanted his life. In order to survive, Zhou Yu'an had to put away all his innocence, put on the most honest and incompetent mask, and use this ability to see through people's hearts to carve out a way out for himself step by step in this cannibal palace.
