With the help of intermediary Dan Shubao, Yu Gao acquired five bottles of Top Grade Emperor Flow Juice and twenty Ascendant Grade Spirit Stones from Luo Chen.
Yes, Ascendant Grade Spirit Stones were used for the payment.
Luo Chen originally intended to pay with Lower Grade Spirit Stones, but two hundred thousand was simply too large a quantity to fit in an ordinary storage bag.
Even though a Golden Core Ascendant Master could afford to buy a storage bag with greater space, having so many Lower Grade Spirit Stones was still too cumbersome.
This made Luo Chen realize that as one's realm increases, the currency used in transactions also subtly shifts.
Yu Gao was very satisfied with this trade.
For him, a defense magic item refining method that wasn't developed internally by the sect wasn't that important.
Moreover, truly refining the defense magic item described within was challenging.
At least, he had to ask a sect Elder to use a lot of materials and only barely succeeded once.
