At twenty-two, Li Yuyu's soul enters the body of Hou Yu'er, the seven-year-old legitimate daughter of a minister. She has no golden finger or pocket dimension, so she works hard to build a business in another world.

"Your Majesty, please move aside. You're slowing down my money-making."
"No. You can only be my little Yuer. Whatever you want, I'll give you everything!"
