True grade entering profound grade was a huge leap.
Just as Holy Son Cang Yongning back then, he had long already stepped into the realm of true grade at Greater Sublime Heavenly Stratum.
His aptitude was naturally significantly worse when compared to the Extreme Medicine Sect's disciples.
In the Extreme Medicine Sect, to be an expert, entering true grade was the most basic requirement.
But there were scanty few who stepped into profound grade from true grade!
The vast majority of heavenly alchemists barely managed to step into profound grade when they were at grade eight realm.
There were even some who could not break through to profound grade at all.
Those who broke through to profound grade at grade seven realm were all peerless geniuses!
Being able to advance to profound grade at initial-stage grade seven, those were all geniuses among geniuses, targets of heavy grooming by the sect.
