I recommend the following novels to you: The male protagonist, Su Mo, had transmigrated into the world of the Painted Pugilistic World series and suddenly discovered that he had been bound to the Vampire system and had become the Progenitor Vampire. From then on, he had become the Vampire Empress's Embrace. The female protagonist was a mutant vampire from the 25th century. She traveled to the Qing Dynasty and accidentally became a vampire exorcist. She became a legendary figure in a world where humans, ghosts, and demons coexisted. The male lead Su Mo transmigrated into the world of Battle Through the Heavens and became the Young Sect Master and the Progenitor Vampire of the Misty Cloud Sect. He carried the power of the Progenitor Vampire and the characters like The Embrace, Yun Yun, and others, and began to roam the world. I hope you like my recommendation. Muah ~
