My name is Gao Yi, an ordinary milk tea shop clerk, but I was accidentally involved in the blood war in the vampire world. When I was selected by the Blood of the Ancestor and received the "Vampire Evolution System", everything changed - those superior female heroines in powerful novels would all become my prey. I pretended to be a weak and cute little puppy, but in fact I had the ability to evolve by devouring blood. When the cold and charming Queen wants to keep me as a blood slave, and when the arrogant Demon Queen wants to use me as a pawn, I will only smile and show my fangs. In this world where vampires and demons run rampant, I used my weak appearance as a disguise to devour the bloodline of the strong step by step, and finally discovered that I was the reincarnation of the sealed ancestor.
