After enduring countless hardships, the hero arrived in the demon realm, ready to defeat the Demon King. He never imagined the demon realm had undergone reforms and now put education above all else. To become an ordinary soldier, you needed a bachelor's degree. Squad leaders had to come from top universities. Passing the postgraduate entrance exam earned you a promotion to legion commander, while a master's or doctoral degree qualified you to become a general. Publishing in an important academic journal came with rewards, and landing a job at somewhere like NASA could even earn you a noble title and a fief. Everywhere you looked, the demon realm's top brass were all bald.
Demon King: "Are you here to challenge me? Let me see your qualifications. How many papers have you published? What projects are you researching?"
Hero: "? I have a junior high school diploma. I only know how to beat people up."
Demon King: "Get out of here! You aren't even a doctor, and you think you can fight me? That's just not how the world works!"
Hero: "What? If I'm going to beat you up, I'm going to beat you up. Do I need to pick a special day?"
Demon King: "No way! I'm the mighty Demon King. Don't I have any dignity? You're going to school right now. I'll pay your tuition! Go! Study! Now!"
Hero: "?"
He was dragged off to school on the spot.
