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.

In the ruins library, you will play the role of librarian and invite those guests who come here with precious information. And your secretary will "receive" these guests well, the winner will take the books he wants, and the loser will become books and expand the library's collection with his own life. With the continuous advancement of the game, you can not only learn more stories, but also get the one you finally want, leading you to a free and unique "book of wisdom".

The game used to be the real ending of Brain Leaf Company. Angela took four-sevenths of the energy from the tree of light, but she was still not free. So she built the "Ruins Library" from the ruins of Brain Leaf Company. Not long after the library was built, Roland, an uninvited guest who claimed to be a nine-level tail-hanging terminator, suddenly appeared in the library, and the story officially began.
