The two woke up after sleeping for half an hour. After waking up, Yinzhen felt much more energetic, which showed that the afternoon nap was indeed effective.

In the morning, Anning explained the honeycomb briquettes and the heated kang (a traditional Chinese bed-stove) clearly, and drew up a lot of blueprints. In the afternoon, the two of them worked together on a complete guide to wool processing.

Wool textile technology actually exists now, but the wool processing methods are relatively outdated, resulting in a limited number of finished products. In addition, the wool has a strong odor, making it not very popular. It is more popular in Xinjiang, but the production volume is not high.

Le Shu's comprehensive guide to wool processing includes how to extract wool, how to clean wool, how to spin wool as efficiently as possible, and the processing techniques for finished wool products.

They worked for a whole afternoon before they finished tidying up, using quite a bit of Xuan paper.

Looking at the compiled results, Yinzhen couldn't hide his smile: "With this, Mongolia, Tibet, and the Western Regions can all be pacified!"

Wool is simply the best way to control nomadic peoples.

Le Shu thought of Guan Zhong; she had studied economics and naturally knew this great man.

"In the past, there was a story of buying deer to subdue the Chu people; now, the fourth prince is buying wool to subdue nomadic tribes?"

"Anzhi understands me!"

Economic warfare is more effective and efficient than bloodshed warfare, even without bloodshed.

Guan Zhong's economic theories and practices were very effective, but few emperors applied these theories to governing the country.

For thousands of years, this land has been accustomed to emphasizing agriculture and suppressing commerce.

"What are your plans next? If you're in charge of this, you'll probably have to stay far away from the heart of the court. Do you want to do it yourself?"

“But someone has to do it. I’ll go and set an example myself, and then I’ll arrange for Ortai to be in charge of it.”

Ortai is a capable man, and Yinzhen finds him useful, so naturally he can't wait until he ascends the throne to use him.
