Is it hard to get rich quickly? My supermarket covers history and the present!

Xiao Yingchun, a social animal, gave up his job and went home to inherit his parents' small supermarket.
One day, a young and handsome general came in through the back door of the supermarket and bought a box of compressed biscuits with silver ingots.
One silver ingot can be exchanged for six thousand yuan!
From then on, Xiao Yingchun began a life of getting rich overnight.
Compressed biscuits, canned food, medicines, rouge, powder and cosmetics, everything is available, and you can exchange them all for gold ingots!
Phoenix men, rich second generation, and greedy relatives, all get out!
I don’t want to be a blood bag or marry into a wealthy family. I want to become a wealthy family myself!
The general paused and said, "I want to marry Mr. Xiao. Is 100,000 taels of gold enough?"
Xiao Yingchun: "I'll give you 10,000 boxes of compressed biscuits, will you marry into my family?"
The general nodded decisively: "Deal!"
