Many Children and Many Blessings, Starting from the Noble Vampire

Multiple girls, all included, vampires, werewolves... The pink-haired vampire princess, the werewolf girl with animal ears, the loli demon hunter, the ice-cold queen, and the noble duke ......... As a human who had just traveled through time, Lin Yan accidentally met Cain. As Cain's first human friend, Cain gave him eternal life. But one day, this vampire power gradually dissipated. Lin Yan wondered if something happened to Cain? But there is no way. The dissipation of power and even flying are problematic, so why not cross the interface and enter the creation world. Until a system called Duozi Duofu was bound to him, he realized that something seemed a little wrong.
