In the primordial age, when heaven and earth were first created, the divine race ruled over the order of the Three Realms. Changsheng was a Celestial Court enforcer who governed the laws of reincarnation. Stern and devoted to order, he broke the heavenly rules when he fell in love with the celestial maiden Jiang Heng. The Jade Emperor flew into a rage, banished Jiang Heng to the mortal realm, stripped away her six senses, and reincarnated her as the spirit of a Manjusaka flower by the banks of the River of Oblivion. She was tasked with guarding the flowers on the Other Shore, with no memory of her past. Changsheng remained in the Celestial Court, his memories of her erased, with only an obsession buried deep within him.
Jiang Heng had once been a celestial maiden whose eyes could see cause and effect. To defy fate and change destiny, she used the first volume of the Wordless Heavenly Book, stolen by Chen Shi, to activate a rebirth formation through four stories of obsession: the love of Liang Shanbo and Zhu Yingtai, Zhen Mi's resentment, Meng Jiang's devotion, and Dou E's injustice. Each time she changed someone's fate, she lost one of her senses, and a petal fell from her flower. Chen Shi had secretly loved her for a thousand years and gave his life to recover her five senses, only to be mistakenly killed by Changsheng. The Flower of the Other Shore bewitched Changsheng and sought to seize his divine position, sparking a war between gods and demons. To protect Jiang Heng's fragmentary soul, Zhao Li took the second volume of the Wordless Heavenly Book into the underworld, where he became the King of Hell and guarded the Bridge of Helplessness. The Wordless Heavenly Book was originally formed from Jiang Heng's divine nature, and could only be restored by gathering love, hatred, and every other human emotion.
Only at the very end did Changsheng remember the past. But by then, he could no longer recognize that scentless red flower as the woman he had once wronged beyond measure. The flower and its leaves are forever destined never to meet, a poignant tale of sorrow across countless cycles of reincarnation.
