Seeing everyone's eyes on him, Tang Yan said, "That's right, it's the Superior Spirit Pill from the Pill Pavilion. Here are the pill recipes. The eight of you take them, and the pills you refine today will be handed over to Du Shu and sold directly tomorrow."

"This pill recipe... Brother Yan, where did you get it?" Wu Xian's face was full of surprise.

"I saw a similar recipe before. With a few modifications, it became the Superior Spirit Pill," Tang Yan casually found an excuse.

Qin Yue'er was skeptical about Qin Fang's explanation. She clearly remembered that a few days ago, Tang Yan had instructed Du Shu to buy the Pill Pavilion's signature pill. If Tang Yan really had the recipe for the Superior Spirit Pill, it wouldn't have taken a week.
