Chapter 535: Chapter 535: Parasite

Nanzhi, Ming Qin, and Shen Miaomiao were engrossed in thought, sitting together in the city lord's residence.

The biogas pit was completed, but they were lacking something to replace the rubber hose for transporting the gas.

They had considered using bamboo, but the bamboo in the city was dry and rigid, unfit for bending and twisting. The ornamental bamboo planted by the wealthy households had either rotted due to soil contamination or grown too thin to be of any use.

While they were worrying, the panting voices of the children came from the top of the wall.

"Zhiyu! Where did you guys slip off to again?"

Seeing all the children lying on top of the wall, Nanzhi was instantly exasperated.

None of those children are easy to manage!

Shen Zhiyu stuck out her tongue, not bothering to defend herself. She quickly jumped off the wall, ready to catch her siblings below.
