Gu Xiu had once studied alchemy under Xu Wanqing at Jade Dan Peak. Though not a master, he wasn't completely clueless either.

Under normal circumstances, with Gu Xiu's current strength, it would be impossible to refine an Immortal pill.

But fortunately, the Earth Cloud Sprout was special. Its refining process wasn't as demanding. As long as the materials were gathered, even a novice alchemist could complete it.

At this moment, Gu Xiu threw all the materials into the alchemy furnace and immediately took out a millstone.
