Chen Feng, a modern gambler who was in debt of millions, jumped into a river and committed suicide. He actually traveled back in time to the third year of Zhenguan in the Tang Dynasty and became Li Shimin's illegitimate son Li Yan who was living among the people.
Starting from a dilapidated house in Hu County, where he was starving and exhausted, he had to get rid of his deep-rooted gambling addiction, use modern knowledge to improve farm tools, design irrigation, and survive at the bottom of the Tang Dynasty. As his life experience gradually came to light, he was forced to step into Chang'an, and as a concubine, he dealt with the whirlpool of Li Chengqian, Li Tai, and Li Zhi trying to seize the legitimate rights, and established himself in the court by making contributions to people's livelihood.
From the county to the palace, from sinner to pillar, this is a self-salvation that spans thousands of years - gamblers must learn to be practical, princes must understand responsibility, and how can a person be reborn in a desperate situation to become the light that illuminates the prosperous Tang Dynasty.
