Armor World the Body Is as Strong as the Armor!

I want to read a book similar to "Armor: As a Human, I Appear at Full Level". In the armor world, the main character is physically very strong. If you don't use armor, you have to obtain some kind of physical strength that can harden armor and supernatural beasts. There are many series of armors, Japanese and Chinese.
