Fu Chun, a Chaos Spirit monk with half-demon blood, was born in a demon world with limited resources. He went to the world of immortality to seek refuge with his biological mother, but was rejected by the top sect Qingyun Sect because of his apparent five-spirit root qualification. When she was desperate, she was taken in by the Tianjian Sect, which was at the top of the world of immortal cultivation but had the lowest financial resources. The sect's Jindan brothers and the Huashen elders who go out to work are all top-notch sword cultivators. They are all equipped with peerless swords, but they can only live in caves and have simple meals every day. Fuqian possesses rare spiritual roots of chaos, possesses a demonic aura that frightens all beasts, and has a talent for cultivation that is unparalleled in both worlds.
