Xia Mi traveled to a classic JRPG game and became a villager in Xinshou Village.

My biggest wish is to save money, then marry a woman from another race, live a safe and worry-free life, and finally die in bed.

On this day, the brave men defeated the Demon King.

【Name: Xia Mi】

[Occupation: Villager]

Added: [Occupation: The new heir to the Demon King]

[Devil King act quickly! Kill all the heroes! Revive the glory of the demon race! 】

Wait, is this a mistake?

In Xinshou Village, besides farming every day, Xia Mi, who is serving as a background board, suddenly has an additional identity board.

He is just a novice villager!

“Where is the devil king! Where is the devil king!”

The news of the Demon King’s birth spread throughout the mainland. Every brave man who came to defeat the Demon King could see a steady stream of monsters in Xinshou Village, but he never saw the Demon King.

Villager of a certain Xinshou Village: Demon King? I’m a farmer, so I really don’t know.
