The Demon Lord Insists on Repaying a Passerby's Kindness

During the war between gods and demons, I was just an extra. I got the location of the grand formation wrong and, by sheer coincidence, rescued the demon trapped inside it.

To avoid punishment, I fled to the mortal realm, but the Demon King followed me there.

The Demon King was extremely grateful and insisted on repaying me.

But making a salted fish like me practice for eleven shichen every day is just too much!

The Demon King, cold and expressionless, said:

"If you skip your training for even one day, no one will be able to save you if you're captured later.

Your training starts today."

Practicing for thirteen shichen a day is completely absurd!

The salted fish says: Where's the enforcement squad? Come and take me away!!

Fake older gong x genuinely older shou

POV undecided. I'll decide based on how it feels to write.

Theme: Cute.
