Apocalypse-Level Shelter: Jiuzhou Hotel

[Post-apocalyptic wasteland + System-run construction + invincible arena + Chinese cuisine + no saintly protagonist] The Red Moon rises, radiation runs rampant, and Blue Star becomes a wasteland overrun by monsters, with society in ruins. Survivors kill one another for half a moldy loaf of bread. Then Su Han arrives in the restricted zone with the [God-Tier Hotel System], shattering humanity's entire worldview. While others despair and await death amid hordes of mutated beasts, Su Han reclines on a leather sofa, enjoying the air conditioning and eating watermelon. At first, the survivors think it's just an ordinary shelter, until they experience the hotel's services... “Are you kidding me? One bite of mapo tofu repairs genetic breakdown? That's not food, that's a miracle drug!” “Staying one night in a standard room removes 50% of the radiation contamination in your body?!” “Getting a back scrub at the bathhouse permanently doubles your physical defense?!” The news spreads, and the whole world erupts. The lofty financial magnates throw around fortunes just to snag a bowl of egg fried rice in the restaurant. Brutal mutant beast kings wag their tails while standing guard at the hotel entrance. Arrogant warlords come to blows over the chance to sleep on the floor. As a million-strong army tries to seize the hotel by force, Su Han watches the enemy turn to ash in an instant under the grand formation and smiles faintly. “House rules: no fighting, and no haggling. I'm just an ordinary hotel owner.”
