I Have a High-Tech War Machine in the Apocalypse

[A slow-paced survival story featuring a male cross-dresser. LGBTQ+ readers, come on in for a cup of tea! (Delighted.) A cautious protagonist + a high-tech armored vehicle. Simple ingredients, not-so-simple plot. A post-apocalyptic high-tech vehicle adventure, serialized in all its glory!] The fall of countless comets killed many people and changed the world's ecology. Summers became scorching hot, winters bitterly cold, and the comets also brought plagues, viruses, and many supernatural monsters. Without a doubt, it was the end of the world. But my high-tech armored vehicle kept me alive when the apocalypse came. Outside, the dead, monsters, and mutated beasts roamed freely. Yet humanity, unable to unite, was still scheming and betraying one another over meager resources. Inside, I had everything: a bedroom, kitchen, shower, automated food-production machine, water purifier, and generator. On top of that, I had ultra-alloy armor, electromagnetic cannons, energy weapons, and plenty of high-tech gadgets waiting to be unlocked. And so my fight for survival began. Want to get in? No chance, whether you're a beauty begging me or someone trying to use power to force me. I know you want to steal my vehicle! I won't let you get away with it! I have to survive!!!
