Three Hundred Years in the Tang Dynasty: I Prove Heaven's Secrets Through Immortality

Liu Yuandu, a night watchman in Chang'an, is in truth the last “Bearer of the Mandate,” having lived through six dynasties. Every hundred years, he awakens a portion of his past-life memories and gains extraordinary mastery of medicine, military strategy, mechanical devices, and more. In the final years of the Zhenguan era, the secrets of heaven fall into disarray, and an assassination attempt on a prince uncovers a conspiracy sealed away for ages. Liu saves the prince and escapes, only to draw the attention of Grand Tutor Du Mingli. Underhanded currents churn through the court, killing intent lurks across the Western Regions, and Turkic wolf cavalry mass at the borders. Every crisis points toward the secret of immortality. After hiding his abilities for three hundred years, he can no longer stay concealed. As fragments of his bloodline's legacy emerge one by one, he wields a bronze gong as a blade and memory as a sword, laying out an age-spanning game amid political schemes and flames of war. (Set in an alternate Tang dynasty.)
