There is no magic in the world, only cracks - "snow marks" in the four-dimensional world, swallowing up obsessions and breeding loneliness.
Jiang Mang was once the extraditer and became the only Xuanwu, but he took the initiative to strip away his divinity and fell into the mortal world. He lives forever, will suffer pain and die, and his memory is broken. He has only one obsession left: to find the "end." The rift evokes his senses, but feeds on memories.
In Raven Ridge in the north, the young Raven's mother died in a fissure, and Obsession was trapped in it. He could see the afterimages of the dead souls and was tortured to the point of collapse. Jiang Mang made a deal with him: I will help you find your mother, and you will take me to the deepest part of the rift.
They went all the way south and discovered that the Holy See was experimenting with rifts, and the clues pointed to an ancient book with an "∞" mark - that was Jiang Mang's own mark. Finally, at the Cape Temple, Jiang Mang touched the body of the "previous Xuanwu" and was shocked to realize that everything was a cycle: falling, forgetting, wandering, returning to Siberia and becoming an extraditer again, and the cycle started over and over again. He never breaks through the frame, He is the frame itself.
Raven began to forget in the temple, and time was frozen. He will always stay in his youthful appearance, returning to the Rift in Raven Ridge, waiting day after day for someone he doesn't remember. Every time Jiang Mang walked out of the snow and said, "I'll help you find your mother," they walked together for a while, then separated, their memories faded, and everything reset.
The snow keeps falling without end.
