In the Primordial Era, Pangu, the God-Demon of Strength, split the heavens and earth with his axe, and most of the three thousand gods and demons perished. The Demon Ancestor, Luo Hou, survived by relying on the demonic path, while the God-Demon of Love willingly answered the call of the Heavenly Dao and offered up the origin of the Great Dao. Blessed by the Heavenly Dao, the god-demon's remnant soul was reincarnated to cultivate anew. When heaven and earth first formed, pure energy rose to become the heavens, while turbid energy sank to become the earth, and countless innate beings were born. The God-Demon of Love should have been born into this world, but a battle between Dao Ancestor Hongjun and Demon Ancestor Luo Hou disrupted the Heavenly Dao. The remnant soul lingered in the river of time for endless ages before the Heavenly Dao captured it and reincarnated it as Zhu Qing, a human youth. The calamity between the Wu and Yaos was beginning, and humanity was in dire straits. Later, a Daoist took Zhu Qing as his disciple, and he began cultivating at Fangcun Mountain.
During the war between the Wu and Yao, he is the Martial Emperor's senior fellow disciple, helping humanity rise.
During the Investiture of the Gods, he is Daji's senior fellow disciple, aiding Shang against Zhou and suffering the loss of the Human Emperor.
Then comes the calamity of Journey to the West.
One day, the blue-robed Daoist gazes at the monkey before him and says with a smile, "Little Junior Brother, it's been more than five hundred years since we parted at Fangcun Mountain. Have you been well?"
