VampireSingle HeroineDouble Cleansing (Also known as Xu Sanwang Sells Blood) Xu Sanwang was in an extremely bad mood for no apparent reason. He was so bad that he wanted to go to the rooftop to see if he had invisible wings. Until he was sucked by the vampire girl, he felt extremely happy. [According to one Jin Shixue, if you want me to suck blood, you have to give me something else]
