These years he has been researching the Demon Essence Pill, but the difficulty of refining demon essence pills is too high. Until now, he has not succeeded in refining them and has instead ruined all three Demon Cores that Yun Xiao gave him.
Yun Xiao opened the porcelain bottle and poured out a grayish elixir.
Staring at this elixir, he frowned deeper and deeper.
"This is!"
"This could be considered a Demon Essence Pill, but it's only of First Rank Top Grade. I used a Second-Order Low-grade Demon Core to refine a First Rank Top Grade Demon Essence Pill. Sigh, I don't even know if that's considered half a success!" Yang Zhenshan was somewhat helpless.
Yun Xiao took out a small knife and gently scraped a little powder off the elixir to taste it.
"Hmm, it should be a Demon Essence Pill!" His eyes lit up, and his frown instantly relaxed.
It has the taste of a Demon Essence Pill, but it's not very useful for Foundation Establishment cultivators.
