Su Yuan, the "Ultimate Evil Demon King" who made the world tremble, suddenly retired.
The reason was simple: it was boring to crush noobs in the beginner village with a max-level character. On top of that, the old principal who knew his identity had tearfully begged him to stop destroying school property.
He'd planned to settle down and live a lazy life, until the fortune-telling granny who had never been wrong made a prediction:
"The savior who will end the age of the Demon King is about to be born among the new students of Starsea Academy of Heroes."
"Someone who can defeat me? That's way more interesting than destroying the world."
To get a look at this so-called "savior," Su Yuan infiltrated the academy and became a team instructor.
He casually took charge of a rowdy squad of eccentric girls whom the star instructors had all rejected.
Faced with these girls, who were supposed to become heroes of justice, Su Yuan decided to teach them a little "terror from the abyss."
And so, the whole tone of the story changed.
Other instructors teach: control your power, protect the city, and know when to stop.
Su Yuan teaches: blanket the area with fire, leave no survivors, and remember, an infiltration is perfect as long as you kill every witness.
"Remember, combat means using overwhelming violence so your opponent doesn't even have time to regret it."
Years later, when the villains saw those Valkyries elegantly sipping tea while casually leveling half a city, they completely broke down:
"Who taught heroes to fight like this?! Why are they even scarier than the Demon King?!"
Su Yuan, the mastermind behind it all, spread his hands helplessly:
"Don't look at me. I only taught them to be 'prudent.' Who knew they'd take that to mean 'nuclear peace'?"
