This is a story about a blacksmith and an immortal, a Taoist priest and a demon, and a scholar and a ghost. It is not an ethereal plot, nor is there any gorgeous vocabulary. When written, it seems that these three people are moving forward on their own, completely out of the author's control. In the end, the immortal does not become an immortal, the demon does not look like a demon, and the ghost does not look like a ghost. It is just that every story is nothing more than human feelings.
