Magical Alchemy: Rising after contracting with a monster.

Alchemists are a prestigious and rare profession, and to become a qualified alchemist, one must first be a wizard. Wizards themselves are a noble and scarce breed. However, when a soul filled with thoughts of AK-47, ballistic trajectories, landmines, skateboards, and other otaku concepts inhabits the body of the most humble and lowly of slaves, and this slave becomes an alchemist, it’s as if a bomb has been dropped into a lake, sending waves crashing across the world.

What’s even more surprising is that this guy not only refuses to follow the ancient traditions of alchemy passed down for thousands of years but also insists on creating outlandish inventions. The water-based magic potions he creates are completely revolutionary, turning centuries of alchemical history on its head, now reduced to tiny granules instead of the usual concoctions. As for his understanding of weapons and magic, it's equally unconventional: "Well, my weapon can directly eliminate your enemies right in your home—who needs a greatsword? And my magic cannon fires hundreds of fireballs in the time it takes you to cast one fireball spell, so who needs a staff? As for potions, it’s all about convenience and portability. But the most important thing is gold, gold, because only with enough gold can you buy all the things you need!” Kent shouted as he passionately defended his creations.
It all started with an accident and a contract with a magical monster...
