As the Mightiest Magus, I Got Magic-banned at the Start?

Alan was once a genius, but due to political struggles, his mana core was shattered, leaving him unable to use magic.
After a fateful incident, he became bound to Hell, gaining a unique way to wield magic.
The cost? Endless pursuit by the deities of Hell.
Whatever.
The world has treated me this way, so I have no reason to show mercy.
Anyone who stands in my way will be killed with a single sword.
After all,
I will be the Lord of Hell.

Warning: This book keeps a fast pace with constant fight.
Contains: decisive and ruthless kills, no saintly hero, no silly face-slapping scenes, crushing enemies across levels.
If you can’t handle a cold-hearted and cruel protagonist, turn back now.
Repost of my last work, the new name: Lord of hell
This time, I want to try something new, hope you all enjoy the fight.
