There are no endless patterns in the ruins library. After entering the game, complete the novice teaching according to the navigation prompts, and successfully open the next level after completing one level. The main interface of the library is very simple. There are only four main scenes: library, invitation letter, book burning, stacks and a * * *. Invitations are similar to the setting of checkpoints. Open the invitation and choose a book to send, then you can enter the battle level. If you win this battle, you can get a book award. If you fail, you will lose the book you sent before.
