Xie Wujin's memory is a burned-out ruin.
As the last descendant of the former sword guard, he bears the blood feud of his family and guards a dilapidated bookstore in the south of the Yangtze River. He uses "Silent Fire" to burn the memory of the assassin and his own past. The price is that he is forgetting everything bit by bit.
Jiang Jinyue is a spy.
She sneaked into the capital with a mission, but accidentally bumped into Xie Wujin's bookstore. She has a "water-tracing mirror" that can peek into other people's memories, but she can't see her own future. When two people walking on the edge of memory meet, the game of chess begins to turn.
The imperial power declined, vassal towns were divided, and rivers and lakes were undercurrent. The centuries-old conflict between the Han clan and the noble clan, the struggle between the royal family and the Jiu Ming Sect for the secret treasure of the previous dynasty, and the "mental realm" that can materialize obsessions... All clues point to the murderous case twenty years ago.
When he burns up his memories for her, when he sees the future clearly for her, where will this journey of snow and ice go?
