Dungeon and Castle 5 is an idle game that employs the classic dungeon collection gameplay, featuring excellent collection and nurturing settings. Many players want to achieve the perfect collection in the game but often fail to do so. Today, I will tell you where the last book in the Book Repository of Dungeon and Castle 4 is located. Many players face the issue of not being able to find the last book in the Book Repository; let's take a look at its specific location together.

In Dungeon and Castle 4, the Book Repository is the core scene of Chapter 9, the Divine Realm. It is an important area for exploring ancient books and also a key battlefield for players to challenge bosses. There are a total of 9 mysterious books scattered throughout the map in the Book Repository. You need to find them one by one to complete the final task. Most of these 9 books are relatively easy to find, but many players get stuck on the map because they can't locate the last book, preventing them from progressing further.

Of course, the missing book might not be the same for every player, but based on the experiences of most players, there are two books that are the hardest to find. One of them is in the lower right corner of the Book Repository, where there is a hidden tree. Clicking on the trunk will give you a book. This tree is very well concealed, making it difficult to spot. The specific location is near the pond. When the player gets close, the tree will change state and glow, making it noticeable upon careful observation.

The other book is inside the Shadow Tower. You can enter the Shadow Tower through a hidden path in the lower left corner of the Elemental Path. A book can be found in a chest inside the tower. Since the game does not have an auto-pathfinding feature, you must explore the map yourself. While exploring, pay close attention to the edges and corners of the map.

After reading my introduction, you should now know where the last book in the Book Repository of Dungeon and Castle 4 is located. The game has a lot of collectible elements, which make it very fun, although it can also be quite time-consuming. It really tests the player's observational skills and attention to detail.
