The male protagonist is born with a spiritual affinity and can form a deep bond with monsters and evil spirits. He can share each other's natural spells by forming a contract with them. The price is that it is easy to provoke high-level weirdness, and it requires balancing all the demonic powers in the body. From relying on Tu Shanyue's fox fire body protection, to drawing talismans and forming formations, to integrating the power of multiple heroines to cast compound immortal spells, and finally comprehending the Yin and Yang God-killing Technique. From a transfer student in the mountains to a non-staff consultant of the city cleaning team, he controlled the local demon clan and eventually became the co-master of both worlds.
