No Escape from the Apocalypse

Against zombies, headshots are useless. The more you hit, the faster you will die. Only in the later stages of the zombie outbreak did the survivors understand this truth - the moment the bullet penetrated the zombie, the thin black thread would eject from the rotten skull and penetrate the survivor's body accurately. There are no superpowers, no evolution, and only the protagonist Wu Qi has a golden finger.
