1. Library: Take the Library of Building 8/kloc-0 of Radiation University as an example. We need to start three generators. We can come to the corner or high place of the library first.

2. Stepped classroom: Take the library on the 82nd floor of Radiation University as an example. There are many infected people in the corridor outside the amphitheatre. Similarly, adjust the drone to the height of the door frame to ensure that the drone cannot be attacked, attract infected people to the corner, pay attention to avoid it, and give priority to attacking infected people who throw stones and spit venom.

3. Basketball court: Take the basketball court on the 84th floor as an example. First, we enter the first room, adjust the height of the drone to be parallel to the door frame, and then attract the infected person to the door. At this time, repair the generator.
