The Void Returns, Gradually Departing

Mo Xugui, a coffin-born child born in the Void Return Realm, meets Tang Jianli, the heroine, who has endured a similarly tragic past but remains optimistic. As they spend their days together, Mo Xugui is gradually influenced by Tang Jingli. He slowly grows accustomed to life in the outside world and falls in love with Tang Jianli. But an accident takes her life. Afterward, the hero develops a bloodlust: every full moon, he becomes uncontrollably murderous. Only the remnant of the heroine's soul can restrain him. Born in a place of extreme yin, Mo Xugui possesses the power of extreme yin within his body, and he quickly realizes this. He uses the coffin of extreme yin in which his mother slept when he was born to preserve the heroine's body in ice, then uses his own power of extreme yin to keep it from decaying. From then on, Mo Xugui travels the world, dragging her coffin behind him as he searches for a way to bring her back to life.
