Now, Isn't That a Surprise?

So, who's really the tougher one?

He is her nemesis, and somehow they keep crossing paths.

The Queen Mother secretly fostered her at the residence of Taishang Laojun. Officially, she is an immortal attendant there, and no one else knows her true origins.

He is the Chief Instructor of the Discipline Bureau. When he comes to Taishang Laojun's residence to collect an elixir, the two become enemies. He wants to take her to the Discipline Bureau and put her through training. Taishang Laojun agrees, the old rascal.

When her origins are finally revealed, she thinks she will never have to suffer his torment again. But then his origins are revealed too: he is the son of Donghua Dijun. Just when she is at her most disappointed, she awakens as the greatest deity under heaven and takes him as her immortal attendant, tormenting him in turn. To her surprise, he becomes her constant companion. What a twist!
