Everyone stared at Lu Jiao in awe then looked back to Xie Yunjin.
Xie Yunjin said, "Don't get flustered. Let Lu Jiao explain."
Everyone turned to Lu Jiao, who started to explain, "As you know, leeches suck human blood and are not kind animals. What you don't know is that leeches are highly valuable. They revive delicate veins, ease pain, and improve blood flow. Not only are they useful for pregnant women, they can help with brain injuries and strokes.
Right now, we don't have a lot of medicine that uses leeches. That is because we don't have enough supply. Because of the low supply, I suspect the purchasing price of leeches are very high. I estimate one pound of leeches to sell for at least 500 coins.
