Since high school history teacher Cheng Yun came back from worshiping his ancestors, he got many strange things.
For example, there is a black mist in the shape of a humanoid whose gender cannot be distinguished. He always likes to make poses and shouts, "Commander, come and play!"
But, but - do you have a personality? Cheng Yun looked disdainful.
Then one day Cheng Yun's old finger was broken, and old blood flowed on the stone. In this way he signed a contract with the ghost.
This is a world with ghosts and gods, but there is a separation between immortals and mortals, and practitioners rarely appear in the mortal world.
But the appearance of Cheng Yun broke this barrier. The riots of the practitioners completely exposed the practice world to the eyes of mortals.
But what kind of magic power does Cheng Yun have that can actually cause the practitioners to riot? It's all in the book "Ghost Contract".
