The Three Great Dao Arts were indeed powerful, but unfortunately, their prices were all too high. The price of the Return-to-Origin Art was even worse. It was extremely difficult to cultivate it from a young age while living in quiet seclusion. One basically had to avoid contact with people and speaking to them, and let others handle as many tasks as possible, so that one's memories would not exceed the amount the secret art could store.
Of course, for the Return-to-Origin Art to be used effectively, a certain reserve of memories was also necessary. For example, if one encountered a stronger enemy and needed to trace back their powers, it would certainly consume an overloaded amount of memory. Thus, in order to make their Return-to-Origin Art even more powerful, the Dongfang Lineage had devoted countless thoughts to the secret arts for preserving memories.
Therefore, if one wanted to cultivate the Return-to-Origin Art to a higher level, one had to cultivate its accompanying secret art to an even greater degree. The more memories one could store, the stronger one would be by comparison. However, the limits of the Return-to-Origin Art were certainly far greater than those of the secret art. Otherwise, the Dongfang House would never have created so many restrictions.
That was also why Dongfang Jin had previously shut her doors to outsiders and instead had the old woman Shenyun guard the entrance and turn away guests. I only came to understand some of it later, after asking Jiang Ruoyin about it.
