Although she didn't know the price of corn, she assumed it wouldn't be much more expensive than soybeans, but it wouldn't be significantly cheaper either. However, the process of extracting oil from corn was less efficient than from soybeans. Three pounds of soybeans could yield one pound of oil, whereas it would take sixteen pounds of corn to produce one pound of oil.
Su Yijia did the math. For the extraction of six pounds of soybean oil, she would only need less than a pound of oil to cover the costs. But if corn were priced similarly, extracting six pounds of corn oil would require her to use two and a half pounds of oil to cover the costs. Nevertheless, in an era where crop yields were generally low, making a profit was already quite good.
She wasn't being picky and didn't dare to be. Many things were waiting for her to purchase medicinal materials to facilitate sustainable development. Moreover, she could take this opportunity to see if this man would deceive her.
