Su Guichen is a wordsmith who specializes in writing "last stories" for the dying. He uses death as the material to write about the end of others, but he has never been able to touch his own inner desire for eternal life. A mysterious commission involves him in an old house without doors or windows - it is said that every book in the house records the price of eternal life for a certain soul. When Su Guichen was reading through those weird and twisted stories, he found that his own life was also quietly written into them. As the memory of the mansion awakens, reality and fiction intersect, and he must constantly make choices: Should he continue to write the end for others, or should he pay the price himself and join the ranks of immortality? But every page warned him that immortality itself might just be a deeper death. The story uses words as a medium to explore the boundary between human nature and eternity. It interweaves horror and philosophy, leading readers into an endless labyrinth of words, questioning the meaning of life between fear and temptation.
