Did you see a Ghost?

Xie Laogen furiously glared at Lu Jiao before he left. Behind him, the next person came up to leave his thumbprint. 

The matter of leech keeping was pretty much settled. Lu Jiao asked the leaders to get organized regarding the participants and assign duties. Right now, they needed people to get leeches, make a temporary leech pond for the caught leeches to stay in, and most importantly, construct the leech-keeping pond.

The leech pond construction was a big problem. If they had plastic film, they could use that at the bottom of the pond. Sadly, that did not exist in this era. The other option was to use cement, which also did not exist. 

Lu Jiao then thought of using fired clay bricks on the bottom. She did some mental math and decided those bricks were too expensive for them. In the end, she suggested they send villagers to dig for rocks and use those as the bottom of the pond. That would save them labor costs.
