Mutant Apocalypse, I Have an Invincible Mechanical Fortress

The Story

Lee Han wakes up in a devastated world with access to a mysterious Apocalypse Bunker System. He begins constructing a mechanical farm on Sunset Hill using a simple welder and a modified harvester. While the rest of humanity fights against zombie hordes and severe famine, he cooks hotpot inside a bulletproof greenhouse and cultivates anti-toxic wheat. He accumulates massive food supplies and raises high walls for protection. By recruiting superpowered individuals, he transforms his agricultural base into an impregnable steel fortress. The structure eventually features heavy artillery and Titan mechs, securing his position as a dominant force in the ruined landscape.
