Li Shen, a modern young man, accidentally traveled through time and became the unpopular tenth prince of Daqian. When he first entered the palace, he encountered difficulties from his brothers Li Yin and Li Zhen. He relied on his wit to resolve the crisis. With the help of modern knowledge, he revived Concubine Yan De with the "True Dragon Crossing Qi Technique" (artificial respiration), offered strategies to gain fame in the imperial examination, improved furniture, brewed fine wine, developed soap and paper, and accumulated wealth and reputation. During this period, he rescued Queen Zhou, quelled the locust plague, foiled assassination plots, and conquered talents such as Xue Gui. In the end, the man with ulterior motives was expelled for setting fire to the papermaking workshop. Li Shen gained the right to freely enter and leave the palace by virtue of his merits, established a foothold in the court and shopping malls, and steadily moved towards the goal of becoming an idle rich prince.
