This is a story about the Song Dynasty in a parallel world. The protagonist Li Shenxing is based on "steadiness", and he always plans things first and moves forward step by step without showing his edge. Using modern knowledge, he started as a poor scholar, resolved crises, made allies, influenced the government, and eventually became a legend. The style is relaxed and humorous, with a touch of the tone of Brother Wen in the prehistoric era: hiding trump cards, countering routines at every level, and occasionally passionate reflection.
