THE STEEL ARK: Hard Survival [Tech Uplift Isekai]

He prepared for the end of his world. He ended up saving another. Dmitry Antonov is not a hero. He is an engineer with a titanium spine, a paranoid mind, and a bank account drained to zero. He spent eight years and thirty million dollars building the "Ark"—a 26-ton expeditionary monster based on a MAN KAT1 military truck. Autonomous. Indestructible. Capable of turning dead wood into diesel fuel. He thought he was ready for anything: sandstorms, financial collapse, isolation. But when a catastrophic anomaly transports him and his machine to a dying world under two alien moons, Dmitry realizes his manuals are useless. There is no GPS. There is no internet. There is only a poisonous swamp, a crumbling castle ruled by a desperate young Baron, and a magical winter that kills without mercy. In a world where steel rots and magic is fading, Dmitry brings the most terrifying power of all: Engineering. What to expect: Hard Sci-Fi vs. Dark Fantasy: Modern technology meets a dying magic system. Competence Porn: A protagonist who solves problems with physics, chemistry, and heavy machinery, not just fireballs. Kingdom Building: Restoring a ruined castle using modern tech. The Truck: The "Ark" is a character in itself. Upgradable, mobile base. No Harem. Just survival.
