Doomsday: You Call This a Hotel? How Did It Turn Into a Mecha?

Reborn in the apocalypse, I, Lin Yuan, activate a god-tier hotel! As the world freezes over, I survey the inferno from my climate-controlled suite. Outside, an icy beauty of a police officer, betrayed by her boyfriend, struggles desperately to survive. I invite her in: "Want to stay alive? Then prove your worth." I bring in the sharpshooting police officer and [tame] a stealthy Shadow Cat. With gene serums, I also assemble a team of genius twins and a cool, beautiful doctor, forming a women's squad that shakes the entire apocalypse! Word gets out, and an iron-fisted war goddess with troops at her command lays siege to my hotel, declaring that she'll take everything I own. I laugh. The hotel rises straight off the ground and transforms into the thousand-meter-tall mech [Titan Fortress]! My goal isn't to build a cozy refuge. I intend to unite every force and establish the one true divine kingdom of order in this wasteland!
