Though the two of them had spoken their lofty words lightly, both Wang Qi and Fan De knew that reverse-engineering the Demon Race's methods would not be easy. It was a massive undertaking.
The Later Demon Race and the Early Demon Race taught techniques but not the Dao. Thus, the human race could easily learn all of the Demon Race's techniques, but the Demon Race would never teach humans their own ways of thinking.
In the long run, the Ancient Dragon Emperor's considerations had indeed been correct. Whether the Later Demon Race or the Early Demon Race, they could no longer advance once they reached a certain level. It was as though an invisible barrier had firmly shackled the steps of their civilizations, leaving them forever unable to develop to higher levels in the form of "civilization." This was the inexplicable barrier spoken of by the dragon race.
Neither the Later Demon Race nor the Early Demon Race had even developed to the dragon race's original level. Their cultures, thought processes, concepts, cultivation methods, and even innate natures might all contain fatal flaws. And those "flaws" could lead to fatal blind spots in thought.
In the short term alone, this truly created enormous trouble for humanity's reverse engineering.
When one's research into the principles was not deep enough, the relatively simple starting point was to follow the designer's train of thought and consider the purpose of every part of a cultivation method. In fact, when those Ancient Method Cultivators demanded comprehension of the "true essence" and "artistic conception" within cultivation techniques, it was much the same—following the few clues left by founders or other cultivators in the names and wording of the techniques to grasp their thinking. Heavenbreak Sword Art was meant to break the heavens, Taiji Fist was meant
