After Tao Ruan died, she made a deal with the System. She would become Shen Lanxuan's master in the cultivation world and help him train until he reached the Tribulation stage.
When the deal was done, Tao Ruan returned to her original world, only to discover that it was the setting of a book and that she was nothing but a doomed supporting character whose life had been absurd and ridiculous.
The System appeared again, turning her, a woman who wanted nothing more than to laze around, into a jack-of-all-trades. By day she was a lawyer, and by night she was a "tailor." Her life became a series of ups and downs.
Just as Tao Ruan had finally adjusted to life as a jack-of-all-trades, her little disciple showed up in her world. Then large-scale mutations began occurring everywhere, along with a series of mysteries that completely put an end to Tao Ruan's lazy life.
When everything was finally settled and Tao Ruan was preparing to retire, her little disciple gazed at her with a gentle smile, but spoke in a sinister voice. "Where are you going, Master?"
P.S.:
1. This novel uses both the male and female leads' perspectives.
2. The author's writing is at an elementary-school level, and the story has lots of original worldbuilding. If you don't like it, feel free to drop it.
3. I'm rather busy lately, so updates are irregular, but I definitely won't abandon the story.
Theme: Life is your own, and being happy is what matters most.
