In the country of Dai Viet, Chen Ming, a scholar from a poor family, lived an ordinary life, but his snobbish fiancée Li Ying broke off their engagement with Zhou Shun and killed his parents. Chen Xiao, a modern sales champion, traveled through time and possessed him. After Chen Ming woke up, he used modern knowledge to improve the economy of Chenjia Village and make it rich. After the provincial examination, he attracted the attention of the emperor for his border articles and was named a counselor. However, he was involved in the prince's struggle for favor. In order to seize the throne, Prince Li Yang constantly hindered Chen Ming from supporting the second prince. If he fails and the second prince loses power, Chen Ming will lose everything. Coming from a poor family, he has to break through his class to complete this seemingly impossible task. During the process, Chen Ming's movements were restricted due to his emotional weakness towards his relatives and loved ones. He was forced to take sides due to the conflict between the camps and fiercely confronted the prince's forces. At the same time, she was faced with a choice between love and career, and was also slandered by the prince. Under the urgent situation of the princes competing for favor, Chen Ming raced against time to help the second prince consolidate his power, resolve crises of trust one after another, and finally successfully supported the second prince to ascend the throne.
