The book gifts in "The Volcano's Daughter" are a very good gift choice in the game. There are many NPCs who like these book gifts. The methods to obtain these book gifts are similar, that is, go to the story corner of the family restaurant to find them. There are also many books obtained.
"The Origin of Divination", "Eight Methods of Cockfighting", "Black Riddle Book", "Red Riddle Book", "Volcano Codex", "Royal Secrets", "Biographies of the Seven Saints", "Secrets of Dice" and "Help You Win the Heart of a Lady"
Special: "Big Monster Picture Book" and "Unicorn Picture Book" (randomly obtained by completing the goals in the early childhood of Spring Fire Year)
Doubtful: "100 Examples of Seat Settings" and "Royal Scandal" seem to only be released in the early childhood years of Spring Fire.
