I Click on the Technology Tree in the Han Dynasty

Dressed as Liu Jingming, the sickly young son of Emperor Wu of the Han Dynasty, Lin Jingming looked at the people of the Han Dynasty whose average life span was less than thirty years old, and silently lit up the "preventive medicine" technology tree. In the first year, he used the "immortal's dream" to present a water purifier, which reduced the diarrhea rate of the victims by 70%. The next year, Jiang Wanqing, the female official who recommended herbal medicine, cured the Queen Mother's diabetes with a bowl of Poria and yam cake. In the third year, he promoted "variolation" and saved 100,000 people from the smallpox epidemic in Chang'an. All the civil and military officials in the court were shocked: "Is His Highness the reincarnation of Shennong?" Emperor Wu of the Han Dynasty was doubtful: "Can my son really strengthen the country by 'curing the disease before it's too late'?" Only Jiang Wanqing knew that the "sterile environment" and "DNA testing" he mentioned did not belong to this era at all. And he even knew that this female doctor with a cinnabar mole on her wrist and an understanding of modern medical terminology was exactly the person he had been looking for for thousands of years. From then on, the Han Dynasty court became their laboratory: The Medicinal Food Shop is the clinical base, the Imperial Medical Office is the scientific research center, and the Western Silk Road is the technology export belt. From "drinking boiled water to prevent diseases" to "national health records", they used a medical revolution to rewrite the history of China's health. Until the archaeological team unearthed the secret treasure of the Han Dynasty, the small characters at the end of the bamboo slips were as clear as new: "To my future self: If you find her, please continue to fulfill our agreement - let everyone in the world not know what a hospital is." [Time travel + medical skills + medicinal diet + infrastructure + group portraits + intertwining ancient and modern times] This is a romance of doctors that spans two thousand years, and is also an epic of civilization that lit up modern medicine in the Han Dynasty.
