Su Mo, a modern social animal doctor, died suddenly from overwork. When he opened his eyes, he was transported back to a young doctor in the Hongwu era. He wanted to live a peaceful life, but he was accidentally bound to a system where Zhu Yuanzhang's voice was eavesdropped all the time. He casually complained about medical skills to prevent epidemics, state governance strategies, and maritime power and industry, all of which were regarded by Lao Zhu as secrets and national policies.
He used modern medicine to save Zhu Biao and stabilize the court, promoted high-yielding crops to eradicate famine, built an epidemic prevention system to eliminate epidemics, opened up the road to navigation and industry, and inadvertently pushed the Ming Dynasty to the top of the world. From a bad doctor who just wanted to bask in the sun, to a virtuous medical sage worshiped by all people, Su Mo lay down to save the world, with a voice that will last forever, and finally became a legend that the time traveler did not want to work hard, but was famous forever.
