The Level Eight Lingjin Tree required growth on a small-scale Wood Type top-quality Spirit Vein, and it needed constant nourishment. It would produce a batch of Spirit Cotton only every ten years.
Even with considerable improvements to the weaving technology, it could barely produce over a dozen rolls of White Cloud Spiritual Silk, amounting to only about one or two hundred sets of clothing. The majority of these were supplied to the Imperial Household or exported to the Immortal Dynasty.
After all, there were too few cultivators in Da Qian who could afford clothes made from White Cloud Spiritual Silk.
This wasn't a matter of affordability, but of willingness. After all, clothes were consumables, unlike Magical Treasures, which could be passed down for several generations.
