Kabanata 974: Chapter 643: Deadline_2

"Generations of Beast Tamers could only try to artificially cultivate and breed certain species of spatial silkworms that were easier to propagate, easier to raise, and cheaper."

"Meanwhile, some exceptionally talented Artifact Refiners continually improved the methods for crafting storage bags, hoping to make them accessible to the vast majority of cultivators in the cultivation world."

"The Green Void Silkworm is, as of now, the most suitable spatial silkworm species for farming that cultivators have managed to breed."

"Green Void Silkworm silk is cheap and remarkably durable, though its spatial capacity is somewhat smaller."

"Today, over eighty percent of storage bags in the cultivation world are woven from Green Void Silkworm silk."

"Of course, there are silkworm species that are more precious than the Green Void Silkworm."

"However, the silk produced by these species, when crafted into storage bags, becomes so expensive that it's beyond the means of ordinary cultivators."
