Three days after completing his bunker, the protagonist discovers that even money can't guarantee safety if the mountain is bombed. Suddenly, a Dino-Taming System activates, giving him the ability to tame dinosaurs and use them to protect his shelter. As meteor impacts trigger a space-time rift unleashing dangerous dinosaurs that devastate civilization, he locks down the bunker and relaxes in the hot spring. While chaos erupts outside with evolved dinosaurs attacking humanity, he confidently sip wine inside, believing his new defense solves the final threat—left ready but the world outside in ruin.
