Goddesses Make Me Unstoppable

Qin Yi's girlfriend, Cheng Yun, and a man named Qiu Zhen humiliate him together and push him off a balcony. As he lies dying, a system switches on inside him. It lets him bind women to him under a master and servant contract, with absolute loyalty on their side, and each task he completes for it can be exchanged for a superpower, food or a weapon. Before this, Qin Yi was a student at Ancheng University, timid and devoted to Cheng Yun. A virus had spread without warning and turned the infected into zombies, and civilization had collapsed. Survivors at the university put together a safe zone, but supplies ran so short that order broke down, and the corpse legion Qiu Zhen commands took over. After the system wakes, Qin Yi gathers the women bound to him into a legion of his own and goes after the gangs holding the ruins, for the sake of whatever survivors are left.
