That was because a little sapling that gave off wisps of purple lightning had already appeared on the lid of Ye Tianyu's Purple Cauldron.
The little sapling was still small. It did not even have flower buds, let alone bear fruit.
The reason was that the Divine Thunder Tower, which could release Demon-Breaking Divine Thunder to help the little sapling grow, was gone.
