"Throughout the generations, Beast Tamers could only do their best to artificially cultivate some, more easily propagated, more easily farmed, and also more affordable types of spatial silkworms."
"Some exceptionally talented Artifact Refiners also continuously improved the methods of refining Storage Bags, hoping to enable the majority of cultivators in the Cultivation World to use Storage Bags."
"Green Void Silkworms are so far the most suitable type of spatial silkworms cultivated by cultivators."
"The threads of the Green Void Silkworm are inexpensive and very durable, although the space is slightly small."
"Today, in the Cultivation World, over eighty percent of the Storage Bags are woven from the threads of the Green Void Silkworm."
"There are also some silkworm types that are even more precious than the Green Void Silkworm."
