You Dug Out My Son's Immortal Bone, So What If I Turn to the Demonic Path!

(Traditional fantasy, passionate power fantasy, growing into invincibility, genius, one heroine, mutual devotion, no System) The young Emperor Ye Guan is peerless in talent and unmatched in combat, yet his status within the clan is lowly because he was born to a concubine. His legitimate-born relatives have always looked down on him. Hoping to establish a separate branch of the family and give his young daughter a safe environment in which to grow, Ye Guan volunteers to guard the bloody battlefield where the clan wages war against the demon race. He slays countless great demons and earns illustrious military honors. But while his young daughter is left alone in the clan, with no one to rely on, disaster strikes. She is harmed by villains, and her innate immortal bones are ripped out and transplanted into someone else, robbing her of the chance to become an immortal. The Emperor returns and, in a furious rage, cuts down his daughter's enemies. With all reason abandoned, he challenges the entire clan alone and is forced to make an enemy of the world, setting out on a wholly new and unknown path of cultivation.
