Chapter 270: Smooth Skin Lizard Hide
Su Bai took out the Wolf Tail Grass Paper, along with a pencil and eraser, and began designing the shape and internal structure of a greenhouse from Earth.
The greenhouse looked simple, yet was complex. The only problem was the lack of plastic film.
Back on Earth, most greenhouses used plastic film to cover the top, which was excellent for heat retention. During daytime when there was no snow or wind, they would open the plastic film for ventilation.
Since plastic film stored heat extremely well, if it was not opened regularly for ventilation, the crops inside would easily be damaged.
“This is a problem. Where can I find plastic film?” Su Bai muttered to himself.
Plastic film was, after all, something manufactured artificially. In Primitive Tribes, where conditions were scarce, it was impossible to produce plastic.
Su Bai scratched his head and began thinking, considering if there were any alternatives to plastic film.
He lifted his cup for a sip of water and mumbled, “This material needs to be windproof, waterproof, and able to store heat. I just need to find an alternative with those properties.”
Yu Ying looked up toward the main seat, seeing the Shaman deep in thought. She felt more motivated by this and began to work in the linen more intensely.
