Xiao Jing, a young man from the Department of Modern History, traveled through time and became the real prince who was subcontracted. He returned to the capital after living among the people for many years. In the last years of Dayin, the government was in turmoil, the borders were in crisis, and aristocratic families were fighting endlessly. He appears to be a playboy, but in fact he has a deep intelligence and secret plan, relying on his skills of identifying treasures and traps. After returning to Beijing, she was involved in a dispute over the real and fake daughter of the Prime Minister's Office - the eccentric Ye Zhen and the cold and deep Xie Qingshuang each had their own secrets. He worked around it, checking accounts and solving crimes, improving farm tools, and promoting the reform of the imperial examination and industry and commerce. From hearing gossip at the tea stall to turning the tide in the court, he used the wisdom of the market to break through power and conspiracy difficulties and used hard work to reverse the situation. There is no golden finger, only talent and action, writing a relaxed and humorous but profoundly transformative legend of the prosperous times.
