Along the way, Luo Chen's Pill Refinement Technique was mostly self-taught, with little guidance from renowned masters.
A remark of "wild path," meant to be mocking, was indeed the truth.
This situation only slightly improved when Luo Chen came into contact with Qingdan Valley's Pill Refinement Technique, and truly turned around when Luo Chen acquired the inheritance of the Refining Heaven Demon Monarch's Pill Dao through the trial in the Alchemy Realm.
However, there were hidden drawbacks within.
The Pill Refinement Technique of Qingdan Valley was too low-level, mostly First Order and Second Order techniques.
The inheritance of the Refining Heaven Demon Monarch's Pill Dao was too eclectic and ancient.
Though it spanned the three realms of humans, demons, and spirits, even the average Pill Refiner mastering one realm would be considered a Grandmaster; how could one master them all?
Even Luo Chen only sought out knowledge useful to himself, absorbing it bit by bit.
