Lin Tian, a Ph. D. In agricultural science who suffered setbacks in modern society, accidentally traveled to the late Ming Dynasty when famines were frequent and people were in dire straits due to academic difficulties and love failure at the age of 35. Facing hunger and despair, he found that his professional knowledge, which was regarded as "dragon-slaying skills", had become his only reliance in troubled times. Starting from a young boy in a hut with nothing, he relied on his advanced agricultural knowledge to grow "magic beans" potatoes with a yield of thousands of kilograms per acre in barren sandy land, which solved the problem of food and clothing. He used his chemical knowledge to brew "Shaodaozi" spirits that were far ahead of his time, and accumulated the first pot of gold. He formed a convoy to fight against local tyrants, and used scientific early warning and prevention of locust plagues to turn natural disasters into opportunities, winning the appreciation of the county magistrate and becoming famous. However, this is just the beginning. When his reputation spread throughout the Ming Dynasty, all forces were ready to take action. How will he use modern technology and wisdom in this turbulent and troubled world to move from the countryside to the court, from a commoner to the world's most powerful man, step by step in the power struggle, win the hearts of all kinds of beauties, and ultimately change the fate of the Ming Dynasty?
