There was a pawn in Kunlun Mountain who crossed the river, named Murong Zhao.
She wore a wooden sword when she was seven years old, and "Tingxue" when she was seventeen years old. She went down the mountain and traveled to the Three Kingdoms. In Liang Guomei's forest, she met a prince who shouldn't be practicing swordplay in the snow; in the cold palace of Yan State, she lit a lamp for a proton who had been imprisoned for ten years; by the Xingxing River in Jiang State, she gave her first kiss to a trembling wolf.
She thought she was just a pawn. After finishing the walk, she realized that the chessboard was hers, and so was the road.
When the guest comes, the sword comes. The guest is from the world, and the sword is her own.
Concept: A pawn crossing the river can also become a chess player.
