The Idle Prince of Chang'an

Modern youth Li Shen accidentally transmigrates into the unfavored tenth prince of Great Qian. Upon entering the palace, he faces harassment from his brothers but resolves crises with his wisdom. Using modern knowledge, he revives Empress Dowager Yan with the 'True Dragon Qi-Soothing Technique', submits the anonymous exam strategy, and improves furniture, brews fine wine, and develops soap and paper to accumulate wealth and influence. He sequentially treats Empress Zhou, quells the locust plague, and foils assassination attempts, securing talents like Xue Gui while maneuvering against forces led by Cui and Prince Wei Li Tai. Finally, Li Tai is exiled for arson at the paper mill. Li Shen gains unrestricted access to the palace based on his achievements, establishes his footing in both the court and business world, and steadily advances toward his goal of becoming a wealthy idle prince.
