A sword manual led to a massacre. A master-disciple friendship, ten years of kindness, and the original intention is finally lost. When Lianyu stood under the peach tree in the courtyard, through the flowers, she seemed to see the young man dancing the sword under the peach tree in the past. But when he came back to his senses, all he saw before him was the vast snowy scene, and there was no longer an old friend. This article is inspired by the song "Snow Between the Eyebrows" and is as faithful to the original song as possible. The plot will be changed to enrich the content.
