This is a time-travel historical novel that tells the story of Wang Yi, a modern physical education teacher, who traveled to the late Northern Song Dynasty (1100) and gradually changed the fate of the country with the help of his offline encyclopedia mobile phone and modern thinking.
He started from the mountain village of Rongzhou, first rescued Su Shi and Qin Guan, then planted sweet potatoes to solve the food problem, married three wives, Xu Wanyan, Li Qingzhao, and Li Shishi, and founded "New Voices from the Government and the Opposition" to supervise hundreds of officials. After entering Beijing, he promoted young talents such as Han Shizhong and Li Gang, formed a new army, and developed firecrackers and cannons. Through a three-pronged approach of economic sanctions, public opinion warfare, and military strikes, we killed Cai Jing and other traitorous officials, recovered the sixteen states of Yanyun, forced the surrender of Xixia, and disintegrated the Liao Kingdom.
In the end, Wang Yi grew up from a penniless "black household" to participate in political affairs, leading the Song Dynasty to prosperity, completely eliminating the hidden dangers of Jingkang's shame, and opening up the "New Era of the Song Dynasty".
