After transmigrating, Xu Yunnuan gets a golden finger: however much silver she has on hand, whatever amount she spends will be returned to her tenfold. On top of that, she can exchange her spending totals for various items.
With her golden finger, Xu Yunnuan opens the most popular cosmetics shop in the land. Before long, it has branches across the entire Sheng Dynasty, and she becomes its richest tycoon.
Life is thriving, and Xu Yunnuan even manages to snag herself a handsome man.
Her handsome man's former wife has passed away, leaving him with a child. Xu Yunnuan is even happier: she won't have to give birth herself.
Then one day, he brings the child to meet her, and Xu Yunnuan stares in shock.
Why does the child look just like her?
P.S. There is an amnesia trope.
A self-indulgent note: The male lead has trouble walking at first, but makes a full recovery later.
Theme: Stay positive and face difficulties without fear.
