They Have Magic, I Have NexusGPT: Modern Warfare in a Fantasy Realm

In his past life, Vane built a god. He created NexusGPT, an AI so advanced that even with heavy restrictions, his treacherous business partner used it to conquer most of the world within decades. Left with nothing but betrayal, Vane died and woke up in a fantasy realm. He didn't ask for legendary swords, divine blessings or cheat skills. He just wanted his creation back. Seeking a quiet, peaceful existence, Vane tried to build a simple life—a quiet house in the meadows. But this world is unforgiving and the cruelty of empires and mages tore that peace away. Now, Vane is tired. Tired of holding back. Tired of chasing a happiness that the universe refuses to give him. Armed with an AI that holds everything from basic carpentry to quantum mechanics, Vane realises something liberating: if magic bends reality, then being freed from a world with rigid laws of physics means he can rewrite the rules of nature entirely. While arrogant mages waste mana chanting to summon inefficient fireballs, Vane condenses superheated plasma into blinding laser beams that slice through armies. Why match their cavalry when you can rain hellfire from high-altitude aerial bombers? To finally secure the quiet life he desires, Vane will build an unassailable utopia. If he has to conquer every kingdom, crush every empire, unearth the origin of mana and control everything under the stars to secure it, so be it.
