Everyone clearly felt the difference in the refinement this time.
Although they could not see all the different changes in the nirvanic rebirth fire, the origin aura emanating from Ye Yuan's body was still Great Dao pressure. They could all feel it distinctly.
Most importantly, Ye Yuan really felt strained this time!
This was Ye Yuan's pinnacle refinement!
Regarding the Hundred Fate Heavenly Aperture Pill, it was pretty much the ceiling of grade eight heavenly pills already.
Wanting to refine it was not that easy.
Refining 300 Hundred Fate Heavenly Aperture Pills at the same time, it was basically Ye Yuan's limit too.
This difficulty was unimaginably great!
Especially Zhou Xianchen, Jinnan, Chu Fang, and the rest, they knew even better how horrifying the refinement this time was.
"If he really succeeds, it will probably be an insurmountable peak in the history of Alchemy Dao!" Chu Fang said with vicissitudes of emotion.
