Third-grade Fairy Expansion Pills were already out of stock in the Yuan family's and the Elixir Production Alliance's stores. In fact, not a single pill had been available for over half a month!
According to some well-informed people, this was a direct result of the difficulty and high cost related to the pills' production. As the pills' production wasn't as profitable as other pills', the quantity produced was quite low. Hence, the scarcity at present.
After all, the minute that some pills were produced and made available, the most influential people would have already placed an order for them in advance. These privileged people would then give the precious pills to their relatives or their subordinates to help them reach the Fairy Realm. This made it nearly impossible for regular people to obtain them.
