Above the cold river, plum petals were floating, and Shen Mo's sword was broken by the whirlpool of fate, but Liu You's hands were as steady as spring water, sewing up his wounds, just like that year when it first snowed.
Born in the mist and rain of the south of the Yangtze River, he has a sword in his hands and a benevolent heart. However, he is dragged into the torrent by fate. He steps into the prosperous capital and struggles to move forward amidst the conflicts of swords and intrigues. Shen Mo has grown from a high-spirited young knight to a fierce warrior stationed at the border; Liu You has transformed from a simple doctor to a guide who holds a light for everyone in the dark night. However, the closer you get to the truth, the heavier the price you pay. Under the secret order, the loyal soul falls; the old trust appears, and the war in the world rises again.
