Immortal Sword Eternal

Those who created the universe are immortals; those who poison the world are demons. An ordinary cultivator accidentally obtained a "spirit-devouring bead" that led to the destruction of his family. After narrowly escaping from danger, he vowed to spend his whole life to clear up his hatred. The treasure has a spirit and is reborn. Just look at him holding a three-foot green blade, shuttling between immortals and demons.
