Apocalypse: I Summon a Mobile Fortress as My Base

[Reborn + special abilities + apocalypse + natural disasters + demons + fortress upgrades + stockpiling supplies + no saintly protagonist] The apocalypse arrived. Extreme weather swept the world, demons ran rampant, and Blue Star’s social order collapsed. Within humanity’s ranks, demon worshippers and traitors sabotaged everything, while demon armies roamed outside. Yang Fan could only watch helplessly as demons overran his small fortress city, home to more than fifty thousand people. Then he was reborn on the very day the apocalypse began. The protagonist awakened his super-fortress ability ahead of time. Drawing on his experiences from his previous life, he blocked the gates and farmed monsters, built his own super-fortress, tracked down his former teammates, and established satellite cities. While others were on the brink of death from hunger, Yang Fan enjoyed fresh meals in his super-fortress, watching movies and playing games with his teammates in total comfort. While others fled from encircling demons, Yang Fan’s upgraded super-fortress swept away their armies with a single cannon blast. When the army was crushed by an enormous Hellgate, Yang Fan drove his mobile fortress right through it and took down the Demon King’s forces with just a few shots. Before leaving, he casually closed the Hellgate.
