A large amount of energy was absorbed into the Postnatal Qi Bottle and transformed into Postnatal Qi.
It also condensed several undigested Cold Qi Pearls for the Small Knife.
The Postnatal Qi Bottle is a Spiritual Artifact, theoretically capable of transforming all gases below the Sixth Realm into Postnatal Qi.
This leftover is presumably because it is an Innate Supreme Treasure nurtured by a Little World.
It's likely the first trace of cold or chill in this world.
Sadly, it's already been used, causing its potential to decrease significantly.
Even so, creating a few Cold Qi Pearls still contains a trace of power beyond the peak Little World, unable to be assimilated by the Postnatal Qi Bottle, thus making it incredibly valuable.
Moreover, even if the Innate spirituality is polluted, preventing it from forming a Spiritual Treasure and further evolving, it can directly be refined into a Spiritual Artifact.
Because every Innate Supreme Treasure contains a bit of spirituality.
