Travel to Ancient Times and Write a Storybook to Become a Knight

Lin Yifeng, a top student in science and engineering, traveled through ancient times and was extremely poor. He found that farming here depends on the sky and medical treatment depends on life, and the people are miserable. So he started writing a storybook, writing compost, crop rotation, first aid, hybrid rice... All into fairy tales. The farmers followed the instructions and the yield per acre was doubled. The passers-by followed the instructions and the dead were brought back to life. The story became popular, the court panicked, and the emperor personally ordered: Find "Mr. Yifeng". But they didn't know that the poor boy who was hiding in the village writing a storybook was planning to earn a title with a pen.
