In 184, Zhang Liang, a Confucian student of Luoyang Imperial College (actually a time travel student in the Department of Modern History), obtained the memory of Zhang Liang, the sage seeker of the Western Han Dynasty, and the fragments of "Heaven's Secret Essentials" in a dream, awakening the power of stargazing and divination. He discovered that Zhang Jiao of Taiping Dao borrowed the "Essential Art of Taiping" taught by the old immortal Nanhua to spread the talisman water to cure diseases, but in fact he secretly absorbed ghost energy to practice the art of blood sacrifice. Zhang Liang had a premonition that the Yellow Turban Uprising would cause chaos, and decided to intervene in history.
