Steel, gunpowder, and spellcasters

Is magic really just a wish-granting machine?
No! In a universe where magic truly exists, the ultimate essence of magic must be as simple and beautiful as the laws of physics.

This is the story of a mass-produced magic combat tool who learns the ultimate essence of magic.

But so what?
Just as birds can fly without understanding aerodynamics, magicians don't need to understand the ultimate nature of magic to use it.
Knowing the ultimate nature of magic does not mean that a tool can suddenly become a great magician.

But the thirst for knowledge is a human instinct, and curiosity is the primary driving force of human civilization. Even with magic, which is inherently illogical, humans still hope to understand its underlying workings.
The pursuit of the ultimate nature of magic needs no reason!

The story in the book takes place in an era where steel and gunpowder coexisted.
Here, firearms are still in their infancy, armor remains the dominant weapon, military theory is evolving rapidly, and innovations in systems and technology are constantly emerging. Moreover, this world has something else that we don't: magic.

The world is undergoing tremendous changes, and no one can remain unaffected.
