I Made A Railgun with Lightning Magic (OP MC / LitRPG / Isekai)

Every mage in this world treats lightning as a blunt instrument. Asher treats it as a power supply. Damian Tesla only wanted to live up to his family name, but died through electrocution by his own underfunded railgun prototype. He wakes in the body of Asher, a five-year-old orphan in a world that runs on magic, and his new body can channel lightning like nothing on Earth. The impossible weapon finally has a power source: him. But Vesperia is a small kingdom holding a single mountain pass against Ironhold, an empire that has already devoured four nations and wants a fifth. Lightning mages here don't get workshops. They get conscripted. Whispers say the empire's war is only the beginning. Something older is stirring behind the storm that seals the north. All Asher wants is to do his research in peace. But to get peace, he will need power. Armed with his knowledge of physics and a perfect lightning affinity, he only hopes it's enough for what's coming.
