— ... Well, if you think about it, the skills the king taught me can be considered "peaceful," which means their scope of application is broader. For example, a fireball is usually used to burn people, which isn't very humane, but... increasing the caliber of one's own rifle and everything related to it is unlikely to be used as a weapon, and it's not as indecent as maiming and killing other living creatures.

The lack of a response to her explanation made it difficult for Leila to fully understand whether Toad had grasped what she had originally meant. She could only hope that he had, so she wouldn't have to explain it again. Although, perhaps she had misinterpreted his reaction, and her explanation was unnecessary.
— With a little imagination, a person can be maimed with practically anything and in any way. And I can also imagine not the most humane use of your techniques. Or a peaceful, albeit easily achievable by other means, use of a fireball. But yes, the main focus of your techniques is peaceful. And quite narrow, to be honest. If we discard completely fantastic scenarios from books of a certain genre, it all boils down to love life and procreation. However, these are rarer skills than the ability to throw fireballs. And the chances of applying them in practice, outside of the king's lessons, are higher, especially if you succeed in winning Ladia's heart. Although, I wouldn't presume to judge, as I'm not aware of the details of your relationship with her and the traditions of Lily. Well, you yourself will be able to teach these techniques to someone in the future, and build a small fortune. I'm sure there will be those who are interested. After all, not every mage is capable of something like this.
