The Invincible Knight Ends the Demon-Filled Middle Ages

[Evil gods and demons + sorcery and battle aura + ruthless killing + exhilarating battles + fast-paced + ultimate power fantasy (skip straight to Chapter 45)] Caesar was reborn into a medieval world teeming with demons and monsters, where people could barely survive and human lives were worthless. The Holy Light sat upon its golden throne, suppressing the evil gods and protecting mankind. Yet reason was burning away, the throne was crumbling, and the world was on the verge of destruction. Sorcerers fought demons, treating mortals like lambs for the slaughter. No matter how powerful a mortal was, they could do nothing against them. But Caesar refused to believe that! Through sheer violence and muscle, he would prove himself a Battle Emperor and bring this demonic Middle Ages to an end! Sorcerers, demons, even evil gods, all of you can die! Crimson, add points! An eight-ring demon wielding the authority of Gluttony bit down on Caesar's neck, only to shatter all its fangs. Its authority over Gluttony failed, and Caesar swallowed it whole, digesting it instantly into nourishment!
