On the seventh day of the descent of the Heavenly Dao, Lu Chen is in a desperate situation, and his bloodline awakens—the ninth generation of the Seal Guardian, inheriting an ancient well, a villa, and a Demon Suppressing Manual capable of recording demon souls and learning demon powers. While others fight for spiritual stones, he operates with care, nurturing a small sect of six people into the number one sect in the entire district. Slaying demons to protect the people, transforming the ferocity of demons with benevolent thoughts, every page of the demon manual is a responsibility. When the tide of demons presses close to the border, he does not retreat; guarding the common people, he does not yield. Facing the conspiracy of the Blood Moon Tower and the disappearance of his father, he fears no powerful enemy, and vows with righteous awe to guard this piece of mountains and rivers well. Where the seal is, responsibility is. He is the ninth-generation Seal Guardian—protecting not just the seal, but the lights of ten thousand households.
