Spirit Controller

This is a world where demon spirits are respected, and humans, who are regarded as blood-eating slaves, are struggling to explore and move forward in the darkness. There seems to be no end to the darkness. When the "demon disaster" came and all living things became extinct, the fate of the human race also ushered in a shocking reversal. By chance, the spirit ancestor signed a contract with the demon spirit, creating a new training system, and the spirit master was born. This novel and its characters are purely fictitious.
