I recommend the book "Primordial Holy Man" to you. The male protagonist has the bloodline of Daoism and possesses a mysterious inheritance and powerful strength. He fell in love with the female protagonist, but died to save her. In the end, he was reborn and returned to the human world to find the female protagonist to reunite. The book has fantasy settings and love scenes. I believe it will meet your requirements. I hope you like my recommendation. Muah ~
