How Do I Deal with Becoming the Villainous Demon King's Master?

Synopsis:

One day, Xiao Ning transmigrated and became the master of the villainous Demon King. Oh no! She was that unlucky old fool whose head the Demon King would chop off and hang at the city gate for three days and nights.

Xiao Ning felt her head. Quick, help me up! I can still be saved!

[System]: "Host, please complete the main quest: torment the villain mercilessly and mold him into a ruthless Demon King!"

Xiao Ning: "..."

So she had to mold Wu Pei into a ruthless Demon King, then kick his head around like a ball?

To complete the main quest, Xiao Ning put on a stern face and ladled a bowlful of carrots, which Wu Pei hated, into his bowl. "Eat them all. Not one piece of carrot left!"

Wu Pei, who had never been cared for before: "..."

Master is so cute. I want to hide her away and devour her bit by bit, ahhhhh!
