Chapitre 109: Extracting Oil

Bai Qingqing picked up a clean willow branch and smiled at Parker with her brow raised. "I naturally have my use for it. Come and give me a hand."

She placed the willow branch into the trough, then asked the confused Parker to place the round stone onto it.

The heavy stone instantly flattened the firewood and a green-colored oil was forced out of it, wetting the wood trough.

Parker widened his leopard eyes.

Bai Qingqing was overjoyed. "Ah! I've succeeded!"

She had come up with this idea by referencing a sugarcane juice machine. Before she completed it, she couldn't be certain it would work either. After all, the sugar cane had much higher water content than tree branches, and it was also much less tough. Hence, she didn't know if she could squeeze the liquid out of the tree branches.

Thankfully, the stone was heavy enough and managed to flatten the tree branches.
