Upon hearing this, Gu Changge took out a pre-written list from his storage ring and handed it to the attendant, saying, "See if you have the spirit herbs listed here."

The attendant glanced at the list, a glimmer of surprise flashing in his eyes. He looked up at Gu Changge and asked, "Are you an alchemist?"

Gu Changge replied with a faint smile, "Not really, I just know a thing or two, nothing worth mentioning."

"You don't seem like someone who just knows a thing or two. It looks like you've at least reached a certain level of proficiency," the attendant said with a smile after pondering over the list for a moment.
