Imperial Tutor: Healing the Ming Imperial Bloodline for Three Hundred Years

A 21st-century doctor of Chinese medicine travels back to the late Yuan dynasty and discovers he is immortal. Hiding between the Ming court and the common folk, he uses his golden needles to save Zhu Biao and Zhu Xiongying, rewriting history with medical strategies. He strictly limits the military power of princes, promotes smallpox vaccination, and harmonizes relations between the emperor and officials, ensuring that Zhu Biao's lineage inherits the throne, preventing the Jingnan Campaign and the Tumu Crisis. Over sixteen emperors, he heals with medicine and saves the nation with medical governance, resolving eunuch interference, border troubles, and land annexation, allowing the Ming dynasty to break the historical cycle and usher in a prosperous era of long-lasting rule and flourishing Chinese medicine, becoming the eternal hidden guardian of the Ming dynasty.
