The Dragon-Slaying Boy in the Magical World

This book is also called: "As a magician, I know how to fight in close combat, but I can't do that" (Time travel + Western fantasy + Elf + Goblin + Giant + Necromancer) Mino came to a different world and possessed peerless magic talent, but he got used to the pleasure of punching to the flesh and slashing the head with a sword. Magician: "I just started chanting magic, and he already appeared in front of me and wanted to chop off my head." Warrior: "I was still on guard against him using magic, and he ducked in front of me and tried to chop off my head." Brain: "I didn't have time to think about anything. As soon as my eyes were blurred, I was separated from my body." Young Mino: "Although I am a magician, I didn't say I couldn't do martial arts!" ———— (The introduction is too weak, please move to the text.)
