The Princess and Her Rough-Rider Khan

Sang Yanlin took a long breath after hearing this. He had been concerned about making mistakes earlier while accompanying Li Xianyun on the inspection and feared that they might have to redo the work—dismantling, rectifying, and reinstalling—which would take a considerable amount of effort. "Young Master, your arrival is truly timely. We just had some questions about the construction of the overturning cart and were hoping to seek your guidance," he said.

Li Xianyun replied with a smile, "Mr. Sang, you’re too courteous. I am younger than you are, so there’s no need for formalities."

The young man was neither arrogant with favor nor prideful of his talents. Gentle, modest, and polite, he was indeed very likable. Sang Yanlin laughed and said, "Alright."

But no matter what was said, how could one not take seriously someone personally appointed by the Khan? He still deserved respectful treatment.

Li Xianyun followed Sang Yanlin to where they were making the overturning carts, where several craftspeople from the Department of Equipment were looking worried. When they saw Li Xianyun, their eyes lit up.

One of the craftspeople picked up a blueprint and pointed at a part, saying, "Young Master, we can’t understand this part."

The overturning cart was different from a tub wheel: a tub wheel simply needed to be placed in the water, and using the water’s flow, it could transport water into the ditches.

An overturning cart, however, needed to lift water from a low place to a high place. It required someone to tread, it needed a power matrix, and if this wasn’t overcome, there was simply no way to transport the water up.

Therefore, the production of an overturning cart was much more difficult than a tub wheel.
