Looking for a Few Smokes at Night

She is a water goddess of a generation, gifted with twin divine seals. Meeting them completely changed her destiny. He is the son of the Innate Emperor, he is ruthless and extremely crazy. He lurks around her and destroys her family. He will do whatever it takes to achieve his goal, and eventually he becomes a demon and goes to a dead end. He was the only remaining dragon bloodline, cold and aloof, but he only had her in his heart. Once he came back and looked down upon the world, he finally kept her after going through thousands of hardships and three reincarnations. "You used to protect me, now it's my turn to protect you." "I will never let you leave me again." He vowed to make those who hurt her pay the price!
