Chen Jingzhai actually thought the price was too high at first, as the elixirs would not be sold at such a price at Elixir Peak.
However, what Sage Hao had said made sense as well. It was normal for one to pay more for such a considerable amount of high-quality elixirs.
Also, Chen Jingzhai believed that the sage would not increase the price for personal reasons, as he was trading with the peak itself and not the sage.
Hao Feng had no authority to increase the price without reason.
Also, not even Mrs. Yang, or even the Peak Master himself, could decide the price on their own.
There was also the fact that there was just no reason for Deacon Hall to pay more than necessary.
It was just proof that the elixirs he created were the real deal.
Instead of accepting spirit stones for payment, he exchanged the elixirs for more Grade 1 herbs, as he had no use for spirit stones at the moment.
