Because of the differences in quality of land and cultivation, materials identified in the Realm of the Gods might not necessarily be the same even though they shared the same name. The Sky Worm Silk in the Realm of the Gods could be completely different than the one in the Sky Spill Continent. Lin Ming identified not with the name, but with other factors such as appearance and smell. If these matched then it was most likely the same thing. But in Lin Ming’s mind, he has only the memories of the Realm of the Gods’ Sky Worm Silk, and since he has not seen the Sky Spill Continent’s version, he could not be sure that they were identical.
Lin Ming thought very carefully about where he could find Sky Worm Silk, and finally concluded that he might be able to locate some in the Seven Profound Martial House.
The majority of martial artists may use the sword, sometimes the sabre, or bow, and so on, but ever-so-often there are those that use extremely rare and precious weapons. For instance, the zither!
The Seven Profound Martial House’s name of Seven Profound naturally originates from the Seven Profound Valleys. But the Seven Profound Valleys’ name also originates from a faction of seven people, each of which uses various weapons. One of them was a female, and her weapon happened to be the zither!
