She Became A Downfall Noble Lady

Hu Jing casually picked up the stack of papers; the one on top only had a few lines of simple characters that seemed to record several types of materials. As he flipped through, he saw that one of the papers depicted something resembling wheels. Instantly, Hu Jing thought of the children’s carts Jinrong had sent to her nephews in the capital. He looked closely but couldn’t figure out the mechanism, while he was sure they were definitely not wheels for carts.

"What is this drawn here?" Hu Jing pulled out the sheet and handed it to Qi Younian.

Qi Younian took it over, "Ah, these are pulleys. We’ve used them before, mostly wooden ones. Ye Zi said that if we get blacksmiths to finely forge a few iron ones, they would last much longer and save more effort. If several are combined together and a sturdy frame is put up when building high structures, it’ll be very convenient and save a lot of effort to lift things up."

"Pulleys, huh," Hu Jing searched his memory for this vaguely familiar device, "Oh, there is such a thing, seems like it’s used for lifting heavy objects."

Inwardly, Ye Xinyan curled her lips, thinking that someone who plays the role of an advisor should be well-read and knowledgeable in many areas. It was just a pulley, and he took such a long time to recall, speaking so uncertainly at that.

Yet, Hu Jing continued, "There have been records of pulleys since the Pre-Qin Dynasty. However, their application wasn’t very widespread afterwards." As he spoke, he picked up the paper again and examined it closely before asking Ye Xinyan, "How does Lady Qi know about such things, and that they can be used in daily tasks?"

Although Hu Jing had mentioned sources from the Pre-Qin era, it did not stop Ye Xinyan from looking down on him.
