In a world where demons and humans coexist, a seemingly ordinary clinical medical student carries the bloodline of a "demon slayer" who is about to awaken, and is burdened with an unclear past with the Song family.
Song Chengyan, the heir to the Song family, Song Yichen, his ambitious cousin, and Song Mu, the silent and powerful demon servant beside them, each approached him with their own purposes.
And deep in this mountain range protected by an ancient demon, the mountain master with long hair hanging down to the ground and contempt for all living things showed a dangerous interest in Chen Mofan's bloodline and lazily proposed a fatal deal: "How about I teach you to kill demons?"
Chen Mofan must deal with his best friends, his new family, and his potential enemies. Perhaps the most dangerous thing is not the monsters that devour flesh and blood, but the greed that cannot be filled deep in the heart, and the one who is powerful enough to subvert everything, but only looks at him differently - the Lord of the Mountain.
