Yun Xiao thought for a moment and said, "I am willing to provide Yang with three Demon Cores to practice. If Yang makes any achievements with the Demon Essence Pill, I hope Yang will help me refine three Demon Essence Pills for free in the future!"
"Of course, this free service doesn't mean one Demon Core for one Demon Essence Pill, as long as the three Demon Cores can result in one Demon Essence Pill!"
The difficulty of refining the Demon Essence Pill is very high, and Yun Xiao has no other way. He has Demon Cores in his possession but couldn't find anyone capable of refining the Demon Essence Pill.
From Master Jing Shui, he learned about Yang Zhenshan's alchemy skills, knowing Yang Zhenshan can refine Foundation Establishment Pills and Illusion God Pills, which indicates Yang Zhenshan's alchemy skills are quite high among Second-rank Alchemists.
