The silkworms that Little Ah Yu mentioned were actually from the spatial pocket shop. There were silkworm eggs inside.
Silkworms that could spit out good silk were very expensive, but they were also prone to dying prematurely. They were only suitable for nurturing in the spatial pocket.
There were also a few other ordinary silkworm eggs. The silk they spat out was similar to the ones outside, so it would not arouse much suspicion.
In addition, there were also mulberry trees that were compatible with the silkworms. These trees were not prone to illness and did not attract pests. The mulberry leaves that grew were long-lasting, fresh, and tender, and they produced very good mulberry fruits.
These were the goods selected by Meatball. Every time it screened, Meatball would also tell Little Ah Yu what these goods represented.
As time passed, Little Ah Yu remembered everything.
