Modern scientific researcher Xu Changfeng accidentally travels through time to become a poor scholar. Right at the start, he is kidnapped up the mountain by a female bandit from Qingfeng Stronghold to be her husband. To lead the stronghold in whitewashing its image and making a living, Xu Changfeng proposes a "merchant-bandit" route, utilizing modern knowledge to brew fine wine, invent papermaking, and run Tianxiang Pavilion, leading all the bandits to get rich through commerce. In the process, he not only matches wits with the magistrate and subdues various strongholds in Qinglong Mountain, but also develops mutual romantic feelings with Meng Xiaonan through daily companionship, working hand in hand to build a massive commercial empire.
