Overwhelming Firepower

In a world of swords and magic, Lucen Thornehart, the eldest son of the Iron Duke, is seen as a disgrace to his noble knight lineage due to his lack of talent and perceived worthlessness. However, his life takes a dramatic turn when a fever unlocks memories of a past life and the game knowledge of a Gun Mage class. Armed with this newfound understanding, Lucen transcends mere guns, inventing weapons previously unseen in either of his lives. These include a heat-generating sword capable of melting metal, a rune-engraved gun that amplifies magic, a colossal sword that causes explosions on impact, and a mana-powered firearm that discharges condensed mana. His innovations extend to advancements in transportation like airships, steam trains, and boats. Lucen Thornehart is poised to revolutionize warfare, embracing a philosophy where overwhelming firepower is the ultimate solution to any problem.
