Ye Xun, a branch of the Ye family with thin fox demon blood flowing in his body, was selected as a "sacrifice" at the family ceremony to quell the "evil" awakening in the ancestral land. On the verge of death, the dormant fox blood in his body boiled completely, which not only awakened his talent for spying on the weaknesses of people's hearts, but also bound him to a mysterious "treacherous contract" system. The system told him that under the ancestral land of the Ye family, there were huge secrets about the world sealed, and his "sacrifice" was just a link in the family's centuries-old conspiracy. From then on, Ye Xun embarked on a dangerous path to survive surrounded by monsters and monsters, and to counterattack despite being framed by his family. He uses the cunning and wit of the fox type to deal with the strange forces from all sides, and obtains power and intelligence through "weird contract" transactions. Every seemingly hopeless encounter brings him closer to the hidden truth: the so-called Ye family who conquers demons may be the biggest "weird". And he himself faced the final choice between his gradually awakening fox demon bloodline and his human identity.
