The Thousand-Change Silkworms laid by the Five Elements Butterflies in the Butterfly Holy Valley possess a rich source of Five Elements.
There has always been a legend in the Butterfly Holy Valley that only a Thousand-Change Silkworm with the Five Elements source can evolve into a Five Elements Saint Butterfly after becoming a Five Elements Butterfly.
As for the Thousand-Change Silkworms born outside the Butterfly Holy Valley, they usually evolve into guards of the Five Elements Butterflies.
This Thousand-Change Silkworm that suddenly intruded here has a more substantial Five Elements source within its body than the ones they've carefully nurtured.
This caused the Five Elements Butterflies floating in the air to be uncertain about which side to support.
The energy of the Five Elements Crystal Stones is too violent, usually absorbed and soothed by the Five Elements Butterflies before being transferred into the Thousand-Change Silkworms' bodies.
