Quick Transmigration: I'll Teach the Worst People How to Be Good

Mo Yutong, a powerhouse in the apocalypse, died fighting alongside the zombies to protect her base, but a System bound itself to her and sent her hopping between worlds as cannon fodder. Turns out, there's no shortage of awful people out there, and she keeps running into every last one of them. Being awful is wrong (except when I do it, of course), so to bring harmony to the worlds, all she can do is teach the awful ones how to be good people.
