This indicated that Gu Shanhai had successfully broken through to the Purple Mansion Stage.
"Oh, it skipped, no wonder it felt discontinuous, seems like I need to compensate for that."
Gu Shanhai quickly became aware of the problem. The Eight Diagrams are born from Tai Chi through Two Instruments and Four Images; hence Four Images give rise to Eight Diagrams. Gu Shanhai's was somewhat chaotic, lacking Tai Chi and Four Images, and although it could be compensated by Yin Yang Five Elements, only a complete set could elevate the entire series.
"Looks like for the Spirit Origin Stage, I need to make up for the Four Images."
This was not a difficult task for Gu Shanhai. His entire system was just referencing the cultivator system of the Xuanji Realm, not exactly the same. For other cultivators, it would be unbearably painful, but for Gu Shanhai, it meant no problem; his own system was unconventional, without distinct precedence.
