SSS-Rank Engineer: Only I Can Create Legendary Weapons

Percy always believed that if you're going to die, you should at least go out with a bang. Unfortunately, his "grand exit" ended up being a bored god snapping his spine like a breadstick.Before that, he was an engineer at one of the world's top aeronautic companies. He had money, prestige, influence and absolutely zero interest. Shackled by Earth's endless bureaucracy, he felt stifled and bored.But death wasn't the end. A goddess of darkness dragged him into a new world, handing him a task: Bring prosperity to this realm. He doesn't really care about divine missions, though, as long as he can build something amazing, he's in.Armed with dual affinities, a dragon's fighting spirit, and a system that lets him customize his own rewards, Percy decides he's done playing fair. Last time, he worked by the rules and trusted competence to win the day. This time? He'll make the rules, and everyone else will be forced to play along.You know the old saying: if you want something done right, get Percy to do it.Yet, as he lays the foundations of invention, power, and conquest, shadows stir. Old gods rise from their graves, prophecies long dormant reawaken sounds like a decent challenge for him.Additional tags:Light Fantasy, slice of life, comedy, System, Magic, Tactical Combat, Power Progression, Monster Hunt, Knights, High Stakes.
