This was not an illusion of Li Fan's; the palace attire on the crocodile mother was definitely of high quality. It wasn't simply made from a single piece of fabric. Not only was the material exquisite, but the colorful patterns were also ever-changing, obviously constructed from many pieces of fine brocade, satin, and damask.
Li Fan remembered, when he was eyeing the purple-jade immortal garments intended for the Golden Core stage cultivators in the shops outside the Dao Tower, he had also glanced at the price of the silks and fabrics.
The word for it was "expensive."
How expensive? In the human realm, without storage magical artifacts, just carrying around one string of Divine Force money, which weighed over ten pounds, was extremely cumbersome and inconvenient. So in this era without paper currency, silk also assumed the role of a monetary instrument for large transactions.
