The Butcher's Knife Dominates Another World

Ryan, an ordinary office worker, accidentally traveled to a game world called "Miracle Asylum"... According to the plot that Ryan knows, in the 700th year when humans and demons reached a "truce agreement", which was the year he traveled through time, cracks began to appear in this peaceful era, because the demons discovered that a "brave" appeared among humans. As a time traveler, Ryan received the strongest protection in history - the protection of the Sword God. "Cut everything with your sword!" Blade length is the only limitation of Asylum. But! The moment he picked up the knife that met the requirements, the side effects were so painful that he curled up on the spot. He only has the strongest protection in another world, but it hurts so much that he can't even lift a knife. No matter how strong the protection is, it's just a decoration. What's the difference between this and a loser...
