Reborn Before the Apocalypse, I Spent All My Money on Heavy Trucks to Build Super Weapons Reborn one day before a mecha apocalypse, the protagonist spends all his money on a heavy truck, transforming it into a gigantic combat mech. By hunting “steel beasts” and absorbing kinetic crystals, he continuously evolves his power. Together with his teammates and the super blade Flame Demon, which emits extreme heat, he sweeps through all enemies—even slaying a 40-meter-long steel python. Faced with the selfishness and ingratitude of the crowd relying on the survival base, he decisively turns his back on them, choosing to carve out his own destiny in the brutal world.
