After dismissing the drones, Shiro opened a portal to check the harvesting of the mana potions and immediately saw the production was decreasing in speed.
Without the gate to the Beyond, the liquified mana wasn't being produced anymore so this was their last batch of potions. She didn't know how long her condition was going to last so she had to be careful with how much she drank.
Of course, their current stock was ridiculously large since they have been harvesting non stop for several months. But just because they have a large stock didn't mean it wouldn't run out.
With no way to replenish it right now, Shiro had to regulate the sales a little for long term use.
"Hmm maybe I should increase the price of the potion by a little and reduce how much is being sold to each person." Shiro muttered.
"That way we can regulate the sales and keep some for ourselves if we need it since it's very useful having a potion that can fully replenish your mana pool."
