I recommend the following novels with invincible protagonists to you: In "The World's Struggle in the Other World," the main character had a special system and slowly became invincible. In "The Vanguard Throne," although the main character was not invincible at first, he would slowly become an invincible existence. In "Time Travel Begins From Invincibility," the protagonist was invincible from the beginning, but the later stories focused more on intellectual warfare. In "Salvation of the Otherworld Continent," the main character was an invincible existence, and there were many other superpowered characters. In One Punch Hunter, the main character was invincible and could easily defeat any enemy. I hope you like this fairy's recommendation. Muah ~😗
