What books should I read to study the twelve immortals on the compass?

This is a unique idea, but it can really be studied and really set a precedent. First of all, I really haven't seen any compass marked Twelve Immortals. This is the content of the four pillars. Although geomantic omen often involves the five elements of birth and death from prison, learning on a compass feels like practicing long-distance running in a swimming pool.

If you want to study the compass, there are really no very good books in this field. Books such as Compass Comprehension seen in the market have not been taught, and there is not much knowledge expansion, so it is difficult to estimate by self-study. If you study the four pillars, you can read many books. I suggest you start with the True Solution of Ziping, then read Yuan Hai Ziping, Shen Kao and Ming Manuscript, and finally you can study DiTianmu. Of course, you can also look at Tianyu Jing and Qing nang Jing.
