In the winter of the thirteenth year of Jinghe, Guo Jiuchuan, the prostitute of Yan State, was humiliated in the deep palace of Liang State. A red-tasseled spear broke through the wind and snow, pushing the young general Ji Fei into his fate. The proton and the prince, the prisoner of the defeated country and the sword of the country, should have been the old enemies at both ends of the chess game, but they formed a life-and-death bond under the palace wall covered with plum branches and snow. The Tonggui Sword is engraved with "Ming Yuan" and "Cheng Yuan", the wolf's stone jade pendant hides the promise of betrothal, and the flames of war will eventually burn away all tenderness. From the snowy night in Chang'an to the bloody battle of Suzaku, from the deduction of the military book before the Qingyu case to the tears of the broken hairpin at the bottom of the Qinhuai River, they took the mountains and rivers as their focus, and stepped into disaster step by step in the gap between power and true love. When Yan flags were planted all over the Liang soil, the vow "If you die, I will never live alone" eventually became the sharpest knife in troubled times - cutting off the way of life and shattering the bright moon.
Concept: On the chessboard of power, no one can be alone. The righteousness of family and country is both a shackle and a belief; personal love is a weakness and a salvation. When the blade of fate cuts the mountains and rivers, only the most sincere blood can prove that under the imperial arts and the smoke, there is still something more important than the hegemony of the king - it is the unmelted snow on the plum branches, the undried blood in the sword marks, the question "Are you cold?" When you were a boy, the heartbeat that you dare not express in your life.
