The Flower Fairy's hostility was no longer disguised; Jiang Chenyu subconsciously circulated the True Qi within her body, only to feel it stagnate and unresponsive.
"You…you've poisoned me?"
"It's not poison, it's Concentration Powder."
The Flower Fairy said coldly, holding the Sky-splitter in her hand.
Jiang Chenyu's heart sank; Concentration Powder wasn't poison but a medicinal aid for cultivation, requiring several precious spiritual medicines to concoct.
As a cultivator reached the Upper Realm, the size of their Qi Sea remained relatively unchanged; at that point, cultivators could seek a higher quality of True Qi.
Just as water can be gaseous or liquid, Upper Realm cultivators pursue the liquefaction of True Qi. However, True Qi isn't water; it won't turn liquid merely by high compression, which is why Concentration Powder was developed.
