My Trouble-Making Xianxia Heroine

This is a cliched tale of immortal heroes:

A divine creditor helps two debt-ridden mortals work off what they owe, while also eliminating a hidden threat that could bring disaster upon all living things. Along the way, he shatters the evil plan of a group of unchecked immortals who intend to trade all living beings for eternal life.

The unchecked immortals lodge a stern protest: "Shut up! Stop talking nonsense. The immortality plan was that A Ning's idea in the first place. Why is it fine when she does it, but not when we do?"

A Ning, the divine creditor, says, "Stop talking nonsense. It wasn't me. I didn't do it. A thousand years ago, you were the ones who forced me to sacrifice myself to save the world. Don't think you can pin whatever you like on me just because I've lost my memories. That 'the weak are always right' routine won't work on me."

Lu Jingfei, one of the debt-ridden mortals, says, "What's the point of arguing? Come up with a cure-all already."

A Ning, the divine creditor, says, "The root of the problem is that they think no one can control them. So let's address the problem at its root. Wiping out their entire race would be inhumane, so let's make them answer to Evernight City too."

Mu Qingyue, another debt-ridden mortal, says, "Agreed."

See? The senior really was telling the truth. A Ning, the young lord of Evernight City, really is either setting a trap for someone or on her way to set one.

So,

Don't mess with A Ning!

Whatever you do, don't mess with A Ning!!

No matter what, do not mess with A Ning!!!

Important things must be repeated again and again!!!!

At this point, Lu Jingfei couldn't help turning to ask A Ning, "A Ning, do you ever set traps for your brother?"

Without even looking up, A Ning replied with two words: "Guess."
