Xue Ling is a nine tailed fox who has been cultivating for thousands of years but lost all his tails in a moment of capriciousness.

I became a side-character who died in anguish because of her good-for-nothing husband.

If I can’t avoid getting married, why don’t I change who I marry instead?

However, after a certain world, the mission is obviously wrong.
