The Demon King Retires, It's Not Too Much to Be a Nobleman, Right?

The devil was tired of living and decided to die once. When he opened his eyes again, he was reborn as a good-for-nothing little aristocrat of the Golden Lion Principality who neither his father nor his mother loved him. He was also packaged and sent to be a lord in the most barren winter land in the empire. The former Demon King and current Lord Ash said he was very satisfied: Just in time, retirement life should be away from the hustle and bustle, farming, fishing, and raising dragons! However, he just wanted to do it, but his strength did not allow it. The seeds thrown away grew into the holy tree of the elves; the magic circle drawn by Boring attracted the prying eyes of the gods; even the native dog he raised was mistaken for the three-headed dog of hell. When Abyss invaded, the kingdom was shaken, and everyone was in despair, Ash yawned and walked out of the castle: "You've disturbed my afternoon tea, aren't you guys a bit too much?" The whole audience was petrified. How could this useless noble who was least looked down upon be more terrifying than Abyss? !
