The Spirit Revives, and the Evil Ghost Becomes the Key to Salvation

The gods of this world have revived, but the gods are not the saviors. They have divine penetration and despise life. After death, resentment, belief, and consciousness combine to form ghosts. Ghosts can sign contracts with people, which is actually symbiosis. But there is also a chance that evil ghosts will fall asleep, and ghosts cannot be killed. A sleeping ghost can be controlled by someone, but if you use too much power, that person will become that ghost. If a symbiote is killed, the ghost will take his body. Or if you have too many abilities, the resentment in the ghosts will corrode the physical body. Humans and ghosts have a master-servant contract. The symbiotic contract is the anti-master-servant contract.
