And after the silkworms grown in these mulberry trees were taken away by the royal family, they made a kind of silk, which is simply the best among fabrics!
They are countless times better than the linen, cotton, or woolen clothes worn by the nobles of the Xiling Kingdom!
But the price of this silk is also extremely expensive!
Clothes made of ordinary fabrics, worn by civilians, generally cost from dozens of silver coins to several gold coins.
The clothes worn by nobles usually cost from a dozen gold coins to a few hundred gold coins.
But a piece of clothing made of silk costs several thousand gold coins, and the more expensive ones cost tens of thousands of gold coins!
This is equivalent to the annual income of a small nobleman!
Such an expensive price may also be related to the low output.
In fact, mulberry trees are now being planted on a large scale in the Yan Kingdom.
The Yan Kingdom is vast and sparsely populated, and many forests are uninhabited. Some forests with poor resources might as well be used to plant mulberry trees. The scale of mulberry tree planting is much larger than that of the Xiling Kingdom.
This is after the fox girl Qing Ling received Lin Yan's revelation, she was preparing to open a "Silk Road" from the Xi Ling Kingdom to the Yong Ye Empire, in order to expand the scale of trade and make the Fire Lord's country more prosperous!
