Reborn: Returning to the Apocalypse to Conduct Experiments

I returned to the days before the apocalypse to punch the scumbag, kick the homewrecker, and pick up a group of adoring girls and boys along the way. Test, test, test? What the hell are you testing for? First beat up the cheating couple, then the parasitic relatives. While everyone else was still stocking up on food, Su Xia had already begun changing her genes. After all, if she wanted to survive, she had to become more terrifying than the zombies.
