Ye Chen was taken aback at the words, and couldn't help but show a bitter smile.
Just recently encountering the recipe for the Dragon Essence Sun Transformation Pill, being able to successfully create a pill in a single attempt was already an extraordinarily heaven-defying feat for Ye Chen in the Dao of Alchemy!
Ye Chen is supposed to have no issues refining Heaven God-level or Holy Ancestor-level pills.
But to refine Heavenly Repair-level, or the Qiankun-level pills in front of him, was basically impossible!
Yet he ultimately accomplished it!
One must know, the Solar Lunar Dragon Transformation Pill refined by Ye Chen is a pill that martial artists in the Qiankun Realm can consume!
Its refinement difficulty is understandable!
But, in the eyes of Xuan Han Yu, what he achieved was unexpectedly not good enough!
This requirement is too high...
Nonetheless, Ye Chen couldn't help but ask: "Fairy Xuan, what do you mean by grade?"
