Many alchemists have the habit of writing books. On one hand, it allows them to review the old to learn the new, consolidating their past knowledge. On the other hand, should they pass away, these works can be left to their descendants as a form of wealth.
Therefore, a book on the alchemy dao authored by an alchemist is their most precious possession, apart from the alchemist themselves. It contains the most valuable experience an alchemist has gathered.
"With this method, it is as if I can frequently exchange ideas with a veteran alchemist. It will be of immense benefit to my path in alchemy."
