Everyone should have seen the big fish monster in the river if they play. We are at the checkpoint where the trailer was taken. On the right side of the gate, we can see the Diaoyutai, with three bodies hanging on it. There is a bell on the right of Diaoyutai and a pull rod on the left to control the rotation of the track. There are many steel bars on the rotating track, and three dead bodies in the middle of Diaoyutai can be cut off.
So, let's use our brains. First of all, we rang the bell on the right, and the fish monster came, cut off a corpse for it to eat, and watched it pull the lever immediately while eating bait there. The steel bars on the next track will all hit the fish monster with the rotation of the track, and then the fish monster will die.
Also, Diaoyutai has a door. Go to the cemetery and look for it. There are AK sniper accessories and night vision devices. Remember to take them away.
Remember to use incendiary bombs in the trailer factory. When zombies chase you, lead them to a narrow area. Molotov cocktails can save you a lot of bullets
