Alex checked for the Silkworms in his Soul Space.
The Heavenly Silkworms were placed in a giant wooden structure with many flat boards where they cocooned themselves. It took multiple years for these cocoons to be ready to be harvested for silk. At the end of the cocoon stage, the worm came out as a moth, almost always becoming a regular silk moth that could pass for any other beast.
Only rarely did they become Heavenly Silkmoths, which could then lay nearly a hundred eggs in their lifetime. Even that wasn't guaranteed to produce Heavenly Silkworms, however, as the chances of the eggs hatching were low as well.
Still, with good care and maintenance, the eggs usually outnumbered the Silkworms turning into regular moths, which meant there was a steady increase of Silkworms since the day Alex had gotten them.
