Yin-Yang Soul Jade has a soul when the world first opened, both good and evil. After thousands of years of evolution and reincarnation, Yang Yu was reincarnated as the idle prince of the current Dahe Dynasty, and Yin Yu was reincarnated as the Demon King of the Demon Realm. There once was an idle immortal who told the emperor of the Dahe Dynasty that there will be a catastrophe in the Central Plains in the near future... One is gentle and transparent, and the other is dark and crazy. See how they resolve this disaster...
Intention: No matter how difficult the future is, I will be with you
