Accidentally Became the Sister-In-Law of the Demon World

Lu Yang is a humanoid blood bag that wants to suck blood from any monster he sees. In order to survive, I had to hug an older brother's lap. The eldest brother is extremely powerful and his job is to subdue demons. Lu Yang follows behind the eldest brother and pretends to be powerful, not to mention how arrogant he is. Until one day, the tail behind the eldest brother was accidentally exposed. "..." "Brother, this is different from the script that was promised..." Lu Yangmao was shocked. "Good boy, come here." The wolf's tail was wagging behind him, "Why should I be the younger brother? The script has been changed and you will be the elder sister-in-law." The force value of the thief is 6, and the psychotic gangster attacks. Vs the cool, tsundere, jealous little cat who loves to explode. The blood is special... Has a magical effect. A brainless sweet article about sucking cats... I hope you enjoy reading it... Thanks to Daming for the cover~ Intention:
