This is a world after the outbreak of the zombie virus. At first, the resurrected corpses just looked scary and had low attack power. After they rotted, no one cared about them, and humans continued to live their lives as usual. It wasn't until the real outbreak came, when the rotting corpses mutated on a large scale one night, and the infected people lurking in the crowd began to lose control, that the world truly fell into despair.
The protagonist has no brainless upgrades to fight monsters, nor any cheats or systems. There are only the struggles and choices of ordinary people in desperate situations. Everyone has their own past and persistence. In the end of the world, or sinking, they will pursue the origin of the virus and slowly reveal the truth.
Intent: In the apocalypse, everyone can become a monster, and only by living can you meet those who are worthy of your life.
