In a world described as an endless sea of suffering, where human bodies serve as vessels and souls as voyagers heading toward a distant land, the Daqian Dynasty reigns supreme, dominating every territory. Yet beneath this facade of prosperity lies a turbulent undercurrent. The eight demon immortals stir, Duke Hong Xuanji of Wuwen grows increasingly powerful, and Meng Shenji, the Lord of the Taishang faction, keeps a vigilant watch over the realm.
Amid this era of great upheaval, the young scholar Hong Yi challenges the world with his initial inquiry. He is the offspring of Hong Xuanji, the dynasty's most influential minister, and Meng Bingyun, the former Saintess of the Taishang faction. Though he loses his mother early in life and is born to a concubine, Hong Yi frequently faces oppression but remains undeterred in his pursuit of knowledge. By chance, he embarks on the treacherous path of cultivating both martial arts and the Dao, defying his predetermined fate, overcoming numerous formidable foes, and ultimately becoming a legendary figure of his time.
