A hundred years ago, ethereal ghost spirits broke through the boundary between Yin and Yang, and the ghost world began to erode the world.
At the cost of blood and tears, humans gradually mastered the method of taming ghosts and built the earliest ghost taming base.
The ghost tamers in the earliest ghost taming bases gradually divided into two major schools:
ghost master, ghost magician
Ghost masters: use their own souls to forcibly capture ghosts for their own use at the expense of their own souls. They are usually short-lived, but the relationship between ghosts and ghost masters is that of slaves and slave masters. Ghosts are usually absolutely loyal.
Ghost magician: uses ghost weapons or some items as a medium to reach a contractual relationship with ghosts to gain combat power. After the ghost magician dies, the ghosts will regain their freedom. It can be regarded as an employment relationship. Ghosts have the right and freedom to leave.
