Zhang Jinze, a master of history and mechanical engineer, was transformed into a sick and weak concubine of the Dudu Palace of the Tang Dynasty. With modern knowledge, he improved agricultural tools, innovated military weapons, made paper, salt and cement. He conquered the Turks at the age of twelve and was granted the title of Kaiguo County Male at the age of fifteen. He wanted to engage in industry in a low-key manner, but was hit by Li Shimin's imperial edict of marriage - Princess Changle promised him to be his wife. He pacified the Turks, conquered the Western Regions, suppressed aristocratic families, and saved the prince. He single-handedly rewrote the fate of Zhenguan and became the number one prince consort in the Tang Dynasty.
