First, the basic mechanism of the game is to collect books. You will send out the first invitation according to the plot, and then the relevant people will be invited to the library. Your goal is to fight them. Winning the opponent will take the book, that is, the plot fails, which will really make the book disappear at first, but later it seems that some books will not be lost. I don't know what the production team wants.

If you win, it will become a book, and then you can use these books to catch more prey and enter the library. As the mysterious version of "The Story of the City" heats up, more and more guys will enter the library, and then the library will increase its available combat effectiveness with the increasing collection of books, so that you can face more powerful guests. In the plot mode, the receiving floor is the same as the wave number of the opposing team, and in the non-plot mode, the receiving floor is based on the maximum building floor.
