I'm writing a novel, and I'm looking for a specific introduction to the double cultivation of magic weapons.

In fact, practicing magic and martial arts are not good. There are too many such books, but you can say what you want.

Double cultivation of magic and martial arts, mainly practicing magic or martial arts, and other auxiliary. You can write that the protagonist used to be a magician, but later he accidentally learned martial arts, or vice versa. Magic martial arts skills to keep fit; Martial arts and magic became stronger, and later, they became a generation of strong people.

You can combine magic with quarrelling and let the protagonist create his own skills and fighting methods.

Well, it's hard to say. Let me recommend some books to you.

Ice, fire, magic kitchen, flame, god of war, etc.
