An iron law of cultivation has existed in the Three Realms for eternity—immortals must undergo romantic tribulations, see through love and hate, before they can become gods. Since the stories of Chen Xiang saving his mother, the Cowherd and the Weaver Girl, and the Seventh Fairy descending to the mortal world spread across the Three Realms, immortals have followed suit one after another. Under the guise of 'crossing the romantic tribulation', they indulge their selfish desires, disrupting order for love, causing demonic beasts to rise on all sides, and bringing continuous disasters to the mortal world. Yet all the karmic debts arising from romance ultimately press down entirely upon the Queen Mother. Having undergone tribulations in the mortal dust and achieved nirvana, the Queen Mother returns with ten thousand years of Daoist heart. She resolves to overthrow the old system of romantic tribulations and launch a grand purge of emotional detachment across the Three Realms. Emotional ties are a crime, and a stirring of the heart is a transgression. Should the discipline of the Heavenly Dao be guarded, or is the ultimate passion of the mortal world hard to abandon?
