I Just Want to Live Until Tomorrow

(No superpowers, hard-core realistic survival, decisive killing, no Holy Mother, no brainless protagonist aura, growth-type protagonist, slow to warm up, enter with high pressure with caution) Doomsday is never a word used to ridicule. The reason why it is called doomsday is that, as the name suggests, it is the darkest and most desperate moment of mankind. When you wake up, your mobile phone will be burned to scrap metal, and the streets outside the window will be full of zombies. Guan Fei has no powers and no system. He only had two daggers handed over by his old father, and one sentence - I just want to live until tomorrow. Supplies need to be grabbed. People must be careful, living people are more terrifying than zombies. No one is a fool in this apocalypse. One wrong move and you'll be doomed.
