Zombie Apocalypse: They Say I'm Not Human

Sound logic + realistic apocalypse + descent into darkness + ruthless and decisive, no saintly heroics + mass production of troops

The focus is on humans versus zombies, with as little infighting as possible, and on the struggle to survive the apocalypse.

Nothing matters more than staying alive.

Morality and feelings are no better than dog shit in the face of death, which could come at any moment!

When the apocalypse arrived, everyone around Lin Huandong turned into zombies. He struggled to survive in his rented apartment, then summoned the courage to leave home just to find a spoiled sausage to eat.

These zombies were nothing like the ones in movies and TV shows. Nearly every one of them was superhuman. Luckily, Lin Huandong awakened the Infinite Troop-Recruiting System. He fought his way through hardship, building high walls and stockpiling supplies.

He is everyone's salvation.

He is also someone the survivors have branded a demon.
