My Master was A Protagonist

Joshua never expected to transmigrate into another world. He certainly never expected to discover that he wasn’t the first one. Years before Joshua arrived, another Earthling had been summoned to this world. His name was Ken Asi Atom. A legendary hero. A man who had gathered companions, defeated demon kings, saved the world, and accomplished everything one would expect from the protagonist of a fantasy story. And now, Ken was the only person who might know how to send Joshua back to Earth. There was just one problem tho. The legendary hero Joshua had imagined was nowhere to be found. Instead, he found a lazy, shameless, salted-fish of a man slouched over his desk. And somehow, Joshua had become his student. If Ken could defeat demon kings and save the world, surely teaching one disciple couldn’t be that difficult… right?yet According to Ken himself, saving the world was easy. Teaching someone was the difficult part. — Description from novelcodex.orgFull novel: My Master was A Protagonist — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
