"I originally used wood ash and some medicinal materials. After my father mentioned it last time, he sent someone to the Shanyu Mansion to inquire and bought some from there." Shao Zhang went up and replied.

"Where did you buy it?"

"Daiguo."

"Where is the country of Dai?"

"The grassland north of Guangning is the place where Tuoba Li grazed slightly back then, and in the early years, the area of ​​the eastern Tuoba Xianbei people."

Shao Xun nodded.

It's natural soda ash.

In the grassland environment, water body replacement is not smooth and rainfall is less, and it is easy to form a salt lake, producing various salts, so soda ash naturally exists.

Shaofu should buy "mouth alkali" from later generations. "mouth" means Zhangjiakou, but the origin is not in Zhangjiakou, it is just a distribution market, but on the grassland further north, where there are many alkali lakes that have been scattered for thousands of years. It is only used by herders and some people in the border areas, which are called "earth alkali".

Very good! It also gives grassland herders an extra way to make money.

In order to help them reverse the trade deficit, Shao Xun was really worried. The most flawed thing is that the effect may not be very good.

If Indian cotton spreads to China in the future and is widely planted in the south, I may have to grab the velvet (wool cloth)

Most of the markets, not to mention that the wool is really bad at this moment, Shao Xun felt thirsty when he touched it.

The hair fibers are also short.

If any of his women wore a pair of wool pants, they would probably have to pill after touching them for a while—·

Before leaving, Shao Xun glanced at the workshop again.

Shi was approaching Ying and whispering something.
Chapter completed!
