章 1142: Little Green Was Tricked Into the Back Mountain

"Ah? Why?"

Lin Yuelan explained, " Before making the vermicelli, the selection of the sweet potatoes, washing, mashing, sun-drying, and other processes must be carried out!"

Mashing it up was not bad. It was like squeezing peanut oil. They just needed to use a large horizontal bar to hit it continuously. They could also use animals.

The other processes had to be done by people.

Lin Deshan immediately said, " Alright, I'll immediately get someone to pick sweet potatoes from the cellar and get the starch out first. Oh, right, girl, how many sweet potatoes are you going to make this time?"

Last year, Lin Yuelan had planted several acres of sweet potatoes and stored them all in the cellar. She didn't need to go out to buy them, which saved her a lot of trouble.

Lin Yuelan considered for a moment and said, " I'll use 500 catties for now!"

She wanted to compare pure manual labor and half-manual, half-machine labor. How much could she save?
