[The end of the world + multiple female protagonists + gene editing + cool writing + system]
When the end of the world comes, I gain the ability to rewrite the genes of life - at the cost of erasing humanity every time I use it. I can turn zombies into weapons, transform myself into a monster, and even reshape the lives of others. But my sanity dropped crazily, the world turned into cold data in my eyes, and my gentle smile was just a "meaningless muscle contraction." Until she reminded me with her body temperature - I am still human. In this apocalyptic world where flesh and blood are intertwined with code, I must choose between "perfect evolution" and "imperfect human nature."
