Transmigration: From Farmer To Empress

Once upon a time-travel leap, Mu Caiwei, the gold-medal bodyguard, turned into a poor peasant girl, Mu Caiwei, who starved to death.
With nothing to their name, and an empty rice vat, facing a skinny, malnourished mother and a bunch of hungry younger siblings, Mu Caiwei rolled up her sleeves and shouted, "Sister's going to get rich!"
Although she had followed a proud and aloof path in her past life, times were now different.
At the small stall, Mu Caiwei donned an apron, zealously crying out, "Fried skewers, fried skewers, all kinds of fried skewers…”
In the fabric store, Mu Caiwei expertly worked the abacus, "This Q version of damask should be sold for fifty taels of silver a piece…”
……
Soon, the people of the Great Jin Nation knew that the richest person in the Great Jin was not only a stunning, young girl, but also a generous and philanthropic individual!
Mu Caiwei couldn't dream that she received a miracle — a magical space, by simply carrying out a few random acts of charity!
She also received an extremely “embarrassing” — predestined marriage!
In a nutshell: The stunning transition from poverty-stricken peasant girl to Empress!
