The Nine Yang Divine Skill was vast and profound, divided into ten realms.
However, the two worlds differed greatly. Even the spiritual energy between heaven and earth was entirely different.
After obtaining the Nine Yin and Nine Yang Manual, the Chen Clan's many powerhouses, including Titled Douluo such as Chen Cong, Chen Zixiu, and Chen Menglin, worked together at the unique Ice and Fire Yin Yang Well to adapt it to the Soul Master system of the Douluo Continent.
Each ten levels of soul power corresponded to one realm of the Nine Yang Divine Skill. Differences in principles and systems meant that interpreting and adapting it took considerable time, and the realms were given new names.
The ten realms were first glimpse of Nine Yang, qi sea condensation, Nine Yang meridian fusion, Nine Yang spirit transformation, return to origin and unite as one, Nine Yang true fire, Nine Yang true body, Nine Yang blazing sun, Nine Yang limitless, and Nine Yang return to one.
After four years of tireless effort, the Chen Clan had successfully adapted the Nine Yang Divine Skill through its eighth realm, "Nine Yang blazing sun."
As for the ninth realm, "Nine Yang limitless," and the tenth, "Nine Yang return to one," their principles were too lofty, profound, and mysterious. Efforts to decipher and extrapolate them were still underway.
According to the deductions of Chen Cong, Chen Zixiu, and the others, "Nine Yang limitless" already belonged to the Titled Douluo level, while "Nine Yang return to one" touched upon the far more profound rules of heaven and earth and might reach the peerless pinnacle.
Meanwhile, the Big Dipper Art from the Nine Yin Manual, which Xiao Yi, Chen Cong, and the others cultivated, had undergone a similar adaptation.
They had likewise adapted it through the eighth realm.
