Iron Powder And Spellcaster

Is magic really just a wish machine?
No, in a universe where magic truly exists, magic must be as simple and beautiful as the laws of physics.
This is the story of a mass-produced magic war tool man who learned the ultimate nature of magic.
But so what?
Just like a bird can fly without knowing aerodynamics, a magician does not need to understand its nature to use magic.
Knowing the ultimate nature of magic does not mean that the tool man can suddenly become a great magician.
But the desire for knowledge is human instinct, and curiosity is the first driving force of human civilization. Even if it is magic that should have no reason at all, humans still hope to understand its inner operating rules.
Exploring the ultimate nature of magic without any reason!
The story in the book takes place in a parallel universe with a social environment approximately in the 16th century of our universe. However, due to a bit of a butterfly effect, the continents and oceans of this planet are different from our geographical environment.
Here, muskets are on the rise, but armor has not yet come to an end. Military theories are changing with each passing day, and innovations in systems and craftsmanship are emerging one after another. And this world has one more thing than ours: magic.
The world is undergoing earth-shaking changes, and no one can stay out of it.
