I’m Really Not The Demon God’s Lackey - Chapter 272: One More Thing

We have all heard the legends of great wizards, but do we know how those stories begin? Ardan Egobar, a young man living in a remote corner of the New Monarchy Empire, does not. He doesn't realize that this story is about him. Not yet...In a world where steam locomotives chug along iron rails, where massive airships hover in the skies, where in the cities you might encounter orcs in suits involved in organized crimes, dwarves with cigars controlling major banks, or elves strutting down fashionable boulevards, where humans have built vast nations on the brink of a world war, almost anything seems possible.Maybe, in such a world, even an ordinary young man, the last of the mountain hunters, might one day become the greatest wizard in history.

Waking up in the body of a 6-year-old boy a few years before Cintra is destroyed, Madara receives a system that gives him the ability to gain the powers of Uchiha Madara.[The peak of Uchiha Madara's system is before he becomes the ten-tails jinchuuriki.]The system's percentage does not stop Madara's power, but rather the system's release. After all, I don't want to see a character who goes around killing everyone from the beginning of the story.

Offered as a bride to Hades at the age of eighteen.

I leaned away as I clenched my teeth angrily: “Worth my foot!”
