There is a kind of incense called Jiuzhuan Huihun incense. There is a furnace called Dumeng furnace. By lighting it, you can enter the deepest memory afterimage of the dying person or the obsessed person. The dreamer is not a bystander. He must play a key role in the dream and guide the dream to the real ending that the person least wants to face - to resolve obsessions and let the soul rest in peace. The price is: every time a dream journey is completed, the dream journeyer will permanently lose a precious memory of his own.
Jiang Wanyin is the last dream master in the world. The half-soul body was soaked in Wangyou water for fourteen years, making her almost numb to all joys and sorrows. Mengze City was destroyed, and her master entrusted her with the Dream Furnace and three months of remaining life before her death, and she set foot on the road to the market. There, she met Shen Che, a wandering violinist - his music could soothe her dying soul fire. He was possessed by a heart-eating curse of thousands of poisons, and he suffered the heart-burning pain of flames every night. Hidden deep in his memory was a frozen palace and a young man chained by iron chains.
This is a story about forgetting and remembering. What you cross is the obsession of others, and what you cross is also your own soul. One furnace dies and another burns.
