Upon gazing around, one sees an array of books—poetry, prose, scriptures, hydraulic engineering, farming practices, and so on. On close inspection, it becomes apparent that the contents one would expect to find in books are all present without omission.
That includes the Spring Palace Diagram.
In the midst of what seems like an endless ocean of knowledge, there is an old man in a blue robe with the hair of a crane and the complexion of a child, holding a book in one hand and the other behind his back.
At this moment, the old man in the blue robe is smiling at Tan Shuchang, "Congratulations, fellow Daoist!"
"Old master, I wonder whence this happiness comes?" Tan Shuchang in fact knows very well why the other would say this.
The person before him looks human, but in essence, he should be like a spirit of inheritance.
