Martial Legacy

A boy named Shi Shan and his little sister were offered as sacrifice to a demon that has been haunting their village. They were rescued by a martial artist who exorcised demons. He took the siblings in as his disciples and taught them the art of cultivation and about the demons that dwell in this world. --- Translated raw sypnosis: He said, "This world fundamentally should not have demons." And thus, all the lands became peaceful.
