Unfortunately for him, the store didn't have any more essence in stock, but they assured him there would be more tomorrow and advised him to come early if he wanted some.
"Then can I pay for them in advance?" he asked excitedly, holding the Qi Grass essence tightly.
Sia looked to Kevin for an answer, and he interjected, "Unfortunately, no, sir. We can't accept advance payment as it's not confirmed if there will be more essence tomorrow. We also have other customers to consider. Please come back tomorrow if you'd like to purchase more."
This caused the young alchemist's excitement to lessen a bit, but he nodded in understanding. As he paid for the essence in his hand, he requested, "Please save some for me if I get a bit late..." and then headed outside.
"I'll try..." Sia replied with an apologetic look, indicating she might not be able to, making him feel a bit more dejected.
