At the dawn of the universe, Sheng Ziqing, the revered ancestor who governed the order of the Three Realms, was persecuted and cast into the cycle of reincarnation to endure tribulations. In this life, he is reborn as Sheng Ziqing, an impoverished country boy in Huaguo. Frail and frequently ill since childhood, he often falls into deep sleep, unaware that the divine nature of the sacred ancestor lies dormant within him. Under the secret protection and cultivation assistance of two immortals, he gradually awakens his spiritual meridians and opens his divine eye. Despite his meager cultivation, the young Sheng Ziqing dares to venture into the Yuqing Tower of Chongming Heaven, breaking through seven layers of illusory trials and mechanisms. Along the way, he befriends fellow cultivators such as Qiu Yan, the young master of Jiuzhentian, and Chi Hong of the Chixia Palace, and subdues ancient spirit beasts such as Xuan Mo and Zhu Jiao.
