Don't Bother Me, I Just Want to Fish Safely

Fighting for hegemony? Don't go! Don't interrupt my fishing... What? Can you fish everywhere after winning the world? Let go of that fish, here I come to fight for world hegemony... A fisherman who is keen on fishing traveled back in time to ancient times. He originally wanted to catch fish safely, but there were too many disputes. So he wanted to create peace in the world first so that no one would disturb me while fishing~
