The young girl's eyes widened in astonishment as she watched Ye Qin pour out four Duanluo pills. Her small mouth dropped open and her sparkling gaze locked onto the vial, "How many more of these do you have left? I want them all!"

Ye Qin peered into the vial with a pensive frown. "There are still dozens left, originally meant for my own use," he said hesitantly. "But if you're so eager to trade, perhaps we could come to an agreement... though your stall seems to have nothing I need at the moment. What would you offer in exchange?"

"Still dozens?" The girl's face lit up with excitement. She thought quickly before grabbing his sleeve and dragging him across ten paces to a quieter stall where her brother sat cross-legged in meditation.

The stall owner was a young man in his early twenties, bearing a striking resemblance to his sister. Dressed in an azure martial robe, he carried a crimson-hilted sword strapped behind his back. Before him lay only one item - a palm-sized bronze cauldron etched with intricate patterns, its price tag reading: "Copper Sand Cauldron - 120 inferior essence stones or equivalent medicinal pills."

Ye Qin whistled at the valuation. This copper sand cauldron was priced higher than an average spiritual weapon.

The girl shook her brother awake and implored, "Brother, trade this cauldron for his pills! Then we'll have enough essence to boost me past the third Qi Regulation stage!"

"That's a lower-grade spirit tool," the young man explained after Ye Qin inquired about it. His voice carried measured authority as he gestured toward the bronze cauldron. "Forged by foundation-establishing cultivators using celestial fire and countless copper sands, this cauldron can withstand the fiery trials of Qi Regulation practitioners. It reduces pill-brewing time significantly while increasing success rates and quality - an essential tool even for advanced stages."

The girl interjected excitedly when she heard Ye Qin was a professional pillmaster.

"True," Ye Qin confirmed.

He'd carefully planned this identity in advance, knowing that as an alchemist he could easily explain his youthfulness with high cultivation and the abundance of pills on his person.

The young man's eyes widened further before he respectfully inquired if Ye Qin were indeed from a fallen immortal family, to which Ye Qin smoothly fabricated a backstory about being raised in a distant kingdom's alchemist clan before their decline.

"Please call me Zhang Zhe," the man introduced himself. "My sister is Zhang Qiao. We're former martial sect members who recently discovered cultivation techniques - newcomers here just like you!"

Ye Qin readily accepted the handshake, noting the siblings' amicable demeanor and shared martial background.

Testing the cauldron with a fireball, he was satisfied by its heat resistance before exchanging forty Duanluo pills for the tool.
