MTL - Returning from the Immortal World - Chapter 1373 humiliation

This book was inspired by My Hero Academia: Adaptation“Who decided being quirkless means you can't be a hero? Those are just rules made by people who never tried to break them.” When a battle-hardened warrior dies in one world and awakens in the body of a quirkless boy in another, the rules of heroism are about to change.Armed with combat experience from a darker realm and an iron will forged in warfare, he sets his sights on U.A. High School - the pinnacle of hero education. But in a society where superpowers are everything, his approach to strength might just shatter the entire system.Behind a gentle smile lies the mind of a warrior. As he builds his power through unconventional means, one thing becomes clear: rules were meant to be broken, and this world's definition of “hero” is about to be rewritten.Sometimes the strongest ability isn't a quirk at all. It's the will to change everything.

I was reincarnated into another world, and I’ve brought the Horadric Cube from Diablo II with me.
Being a knight is cool and all, but being a wizard is pretty neat as well.
So, which one will it be?

- Description from Novelupdates

Years ago, Earth was indoctrinated into the “System.”Earth was not the only place with the System, however. With the System came the other races, Invaders. The Invaders had one goal, to obtain ownership of this new habitable planet. This created a bloodbath, and for years the war raged.This didn't really have much to do with Derek. Derek was kind of a loner. Yeah, he enjoyed the occasional chat or drink with others, but he never stayed in one place too long or really got to know anybody new.Derek did happen to be rather strong. After the years of fighting monster and Invaders alone, he had become quite adept at surviving. One thing that helped keep him alive was his refusal to get involved with others. He rarely cooperated with teams.One day, Derek broke his rules and decided to lend some help, as the mission didn't seem too hard. He should have stuck to being alone.

One day, I was given the mysterious power of Hwanmong.
