Rust System of the Apocalypse

[System] [Zombies] [Not a Saint] [Mecha] [Apocalypse] [Modular]

One day, a malfunction in the time machine Lin Ling built mistakenly sent him seventy years into the future, to a world overrun by zombies.

“Congratulations, Master. You have unlocked the Rust System.”

“Huh?”

Whether the zombies came about through another country’s conspiracy or a naturally occurring mutation is impossible to determine.
