Which bookshelf should I go to? There are many situations. Landlord, if you ask this question, it will make the person who answers it very unhappy. The first one, the most common one, usually has a small staircase next to the bookshelf, which can be scaled down and then climbed up; The second type, hidden stairs, needs to push the bookshelf, and then the stairs behind the bookshelf will appear, which can be scaled down and then go up. For example, there is one in the coffee shop. Just push the cabinet (it doesn't seem to be a bookshelf-) to the left. Third, it is also a hidden staircase, but this one is quite special. There is only one place where this will happen, and that is the home of a doctor who studies Pirok on the left side of Hailar Town. Usually, he won't open the door for you, and he won't let you in until he accepts the help of the library to find the books that haven't been returned. The books to be returned to the library are on his shelf. There are two bookshelves, but there is only one place in the middle where people can enter after being restored. At this time, you need to get a prop (which can make you have great power after being restored). After getting this prop, push the bookshelf away from the gap in the middle, and the hidden stairs will appear. Go up and push the book down. Fourth, the bookshelves on the second floor of the library. This is very simple. Inverting the bottle outside the balcony on the second floor becomes a magical entrance. After shrinking, I went back to the second floor of the library and walked to the bookshelf with the old man in it (the first bookshelf in the first row). The ground is a little different. Walk in. If the landlord still doesn't understand, you can ask me for more details. Thank you.
