The Eight-tier Spirit Brocade Tree must grow on a small top-grade spiritual vein of the wood element, and requires constant nutritional supply, taking ten years to produce a batch of spiritual cotton.
Even though the brocade weaving technology has been improved as much as possible, it can barely weave out a dozen or so bolts of White Cloud Spirit Brocade, totaling one to two hundred sets of clothing, most of which are supplied to the Imperial Family, or exported to the Immortal Dynasty.
After all, there are too few cultivators in Daqian who can afford clothing made of White Cloud Spirit Brocade.
The issue isn't whether one can afford it, but whether one is willing to part with the cost. After all, clothes are consumables, unlike magical treasures that can be passed down for generations.
