Chen Fan, a modern time traveler, became the only son of a fallen prince, but his engagement was broken off by Princess Li Yu. With the help of modern knowledge, he invented many things, which helped the Chen family rise and gain the emperor's trust. However, because of his outstanding achievements, he was excluded and framed by the royal family and conservative forces, and his life was threatened. In this process, on the one hand, he has to deal with crises from all sides, break through class restrictions, and unify the sixteen surrounding countries; on the other hand, emotionally, he is torn between Zhang Ying's silent companionship and Li Yu's possible emotional entanglements. His friends were betrayed or sacrificed in the struggle for power, and even if he eventually became emperor, he would have to pay a lot of price. But he always insisted on changing the ancient backward system so that the people could live and work in peace and contentment.
