Ryu felt that his Master was right, he had been thinking of the Origin Flame too simply. It wasn't just that it allowed him to remember things, it rather allowed him to remember things Perfectly. This was an important distinction and it was something that even Sky Gods couldn't do entirely.
Thanks to the Origin Flame, Ryu was even able to remember that mysterious Mortal Qi he had experienced within his mother's womb. There wasn't a single expert without an Origin Flame that could replicate such a feat.
If he translated this toward his own comprehension instead, the change would be massive.
