Doomsday Fortress: Reborn to Build the Ultimate Bunker

Ten years into the apocalypse, Lin Mo dies torn apart by mutated beasts—only to wake up thirty days before the world ends. Armed with foreknowledge and ruthless determination, he liquidates everything: house, car, maxes out every loan he can get. His destination? A barren mountain hiding an abandoned WWII bunker that will become humanity's last refuge. No system cheats. No naive heroics. Just one man's desperate race against time to transform forgotten military tunnels into an impregnable survival fortress before the aurora rips across the sky and civilization collapses forever.
