Chapter 421: Rebuilding Xiangyang District (V)

Mainuerde Xiaohuochai: "The following was extracted from Baidu. Tuoyue is a piece of equipment used to blast air and burn during smelting. In Laozi, there's a line that says, 'Isn't the world like a tuoyue? It's hollow, but it's not exhausted. The more its agitated, the stronger the wind.' There were unearthed portraits from the Han Dynasty. The tuoyue is made up of three wooden rings, two round discs, and outer leather. It's similar to the bellows, but it isn't as easy to operate. Otherwise, the old man wouldn't have replied in such a way."

Mainuerde Xiaohuochai: "I looked it up on Baidu and it says that the double action reciprocating bellows was the most important blast technology invention in China. It's certainly more advanced than the tuoyue!"
