[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.

However, one day two Shogunate ninja approach him with the news that his four students have gone rogue and have stolen a portable modular nuclear reactor, and thus they ask for his help in bringing his students to justice.
