Yun Hai, a modern ordinary person, accidentally traveled to Chang'an of the Tang Dynasty in the second year of Zhenguan (628) and became an ordinary noble. Based on the technical foundation of the Tang Dynasty, he started by improving the traditional method of boiling salt, and gradually gained Li Shimin's attention. After that, he introduced high-yielding millet seeds (to replace potatoes, in line with the crop background of the Tang Dynasty), improved weapon forging techniques, and was deeply involved in the military and political affairs of the Tang Dynasty. In the process, he and Li Shimin developed from monarchs and ministers to teachers and friends, formed a military friendship with Cheng Yaojin, and began a love affair with Li Qiumei across time and space. He used political mediation to prevent Li Chengqian's rebellion and promoted peace between the Turks and the Tang Dynasty (instead of a direct alliance, in line with the Tang Dynasty's ethnic policy), but he fell into crisis due to Hou Junji's rebellion. In the end, Yunhai gave up and returned to modern times, ended up in the Tang Dynasty as a "virtuous prince", and established a family system. The pragmatic innovation concepts he advocated influenced later generations, showing the collision between modern thinking and the Tang Dynasty system, and the process of knowledge helping the prosperous age.
Very nice! Real!
