Zhao Wu fell into a deep sleep while playing "Swordsman in the Snow" for the sixth time, and when he opened his eyes again, he became the eldest prince of the Liyang Dynasty with the same name as him.
This is a world that is both familiar and completely unfamiliar. His arrival was like throwing a stone into water, quietly rewriting the established trajectory of destiny. From the helpless prince after his grandfather passed away, to the King of Wu'an who single-handedly set off a major Jiangnan case that shocked the government and the public, to the prince of the military supervisor who followed Xu Xiao's Northern Liang cavalry all over the country... In this magnificent chess game, with a touch of inspiration from modern times and an ambition that is unwilling to be inferior to others, he works step by step to push the future of himself and the entire world to heights that no one expected.
(A new perspective and original context, interpreting a temple and rivers and lakes song that belongs to the time traveler.) (More secondary settings) (Plausible world in the snow)
