Graduated from a modern engineering college + senior history enthusiast, engaged in engineering design work before time travel, and has a solid foundation in machinery, materials, and agriculture. Traveling back in time to the early days of the Qin's destruction of the Six Kingdoms in 221 BC, he became the only son of Ling Bo, the hero of the restoration of Lingjia Village in Yueyang County, Guanzhong (he was originally 16 years old and died young due to cold and frailty, and Ling Ye's soul passed through him). Ling Bo once followed Wang Jian to conquer the Chu Kingdom, and he was a very long official. He recovered from being disabled due to an arrow in his leg and returned home. With his military exploits and prestige, he became the "Li Zheng Assistant" of Lingjia Village and the three surrounding villages, responsible for mediation and public security. Ling Ye has a calm and pragmatic personality and strong empathy. In the early stage, he took "survive and raise his family well" as his core goal. In the middle stage, he developed the ambition to "strengthen the country and enrich the people" after his invention benefited his neighbors. In the later stage, he established the ultimate pursuit of "promoting the globalization of Qin civilization". Behavioral style: Make decisions before acting. He is good at combining modern knowledge with the actual conditions of the Qin Dynasty. He does not blindly advance and pays attention to the feasibility of technology implementation. He is neither humble nor overbearing in the face of power. When faced with bullying, he uses his wits to win. After his strength is improved, he has both iron-bloodedness and benevolence.
