村长杜勒盖普对面的图书馆 延伸出来的一个塔楼 需要踩着伸出来的圆形支架爬到最上层。

You need to go run up the stairs inside the building on the platform where Durgeff is standing. Then at the top you exit the building, go around to the back, climb up the building and then go along and jump off the ledge in southwest direction to get onto the square wooden roof with a hole in the middle.
