Capítulo 1849: Chapter 1839: Revealing the Strange Fire

"Master Du, isn't this requirement a bit too high?"

A young Alchemist spoke up.

In the entire Tuoluo Plane, there were a few young alchemists capable of refining Yin-Yang Rejuvenation Pills, but to succeed within the time of one incense stick, only those in Wang Cheng may be able to do so, while others definitely lacked the capability.

"I've said, Misty Rain Building does not raise useless people; if you can't even refine Yin-Yang Rejuvenation Pills, what's the use of keeping you in Misty Rain Building?"

Du Yan said unapologetically.

This selection of alchemists was not for Misty Rain Building, but rather for handling matters for the Chu Family, and naturally, Misty Rain Building dared not be negligent.

"I think that only Wang Cheng could meet this requirement," another young alchemist said.
