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.
