Zheng Qing politely declined the goldfish's sales pitch.
The enthusiasm emanating from the goldfish's expression suddenly dissipated, and its tone turned notably colder, "Since that's the case... may I ask what brings you here?"
"To attend the Market hosted by Spring Guest," the Warlock answered cautiously.
"Please show your invitation and specify your introducer," the goldfish demanded with utmost seriousness.
"This..." Zheng Qing hesitated, uncertain whether to show his invitation to the large goldfish in front of him.
"I am the gatekeeper at the entrance of the Market," the goldfish flicked its tail—allowing the magic rune on its fin to become even more conspicuous—and spoke with notable pride: "...all guests wishing to enter require my verification!"
If you hadn't also been moonlighting as a peddler just now, your credibility might be a bit higher.
