Heaven and earth began in chaos. When chaos first opened, pure qi rose to form the heavens, while turbid qi sank to form the earth, giving rise to myriad worlds. Yet chaos must have an end, just as it had a beginning. When chaos is extinguished, all things return to the void, and everything begins again, cycling endlessly without end.
In ancient times, the sole being of primordial origin was born in the chaos: Chen Xuan. He wielded the power of chaos at its source and upheld the order of heaven and earth, embodying order itself. But at the end of chaos, a consciousness of annihilation split off from his origin, forming a "mirror image" with the same source but a different mind. The mirror image had only one mission: to restart chaos and return all things to the void.
Chen Xuan and the mirror image fought, shattering heaven and earth. At the cost of his own origin, Chen Xuan summoned the Eternal Stone Gate to seal the mirror image. His origin shattered into countless fragments that scattered across the Myriad Worlds. His physical body fell into the mortal realm, his memories were lost, and he was forgotten during a long slumber.
As the years passed, the seal weakened. The scattered fragments brought disasters, and hidden currents stirred throughout the world. An evil sect called the Blood Fiend Sect gathered the fragments, hoping to release the mirror image and seize control of the new Heavenly Dao after chaos restarted. The mirror image's consciousness also awoke within the seal. Its heartbeat passed through the Stone Gate, calling Chen Xuan to return.
Chen Xuan awoke in a teahouse south of Qingzhou City, having forgotten everything. But he did not know that his awakening meant a new cataclysm was about to begin. He and the mirror image were not opposites, but two sides of the same whole. Only by merging their consciousnesses into one could they end the cycle of chaos and forge an eternal Heavenly Dao.
