The specific method is as follows:

1. After entering, talk to NPC first, then light the oil drum next to it and change the flamethrower in the middle of the forest. After clearing the monster, you will brush a slightly stronger monster and open the door to enter the university with the key on it.

2. After entering, it is suggested to hit the house on the left first. After opening the door, there will be a small elite monster (warrior five scum). After the abortion, take the key to open the door to save the first person, and then enter the building directly opposite the flower bed. There will be ammunition boxes inside. You can accept it or not.

3. Then give priority to the people on the right-hand side of the building, then jump directly from the second floor to 1 building (jumping on a table or stool can avoid falling) to save 1 building, and finally save the left-hand side. After the rescue, go directly to the back garden and wait for the monster to brush it out. After killing it, take the key to open the door of the back garden, go in and turn right to the second floor, open the second door on the left and jump out. There will be one.

4. After the mobsters are cleared, you will be allowed to hold the audience, and then brush them up in waves. When not brushing monsters, there will be a monster at the lower right of the audience. After killing, get the key and go directly to the engineering building, regardless of NPC.

5. Use the key to enter the door and go upstairs. There is the last NPC in the last room on the left. Standing next to her triggers the plot and then goes straight out of the engineering building to paint the elite monster. Go to NPC to trigger the plot after brushing and killing. Go directly to the auditorium after the rescue and wait for the helicopter to brush it out. The helicopter has two refresh points, most of which are painted in the lower left corner of the audience. Small probability brush on the basketball court. It's over when you get on the helicopter.
