Down in the garage, there were no people around as everyone was afraid of encountering zombies and they hid in their houses.
So, it was easy for Leng Pan to take out a large car. The zombies were still not as dangerous as the ones described in the novel where a zombie could literally tear open a car.
So, instead of using the bulletproof vehicles she and Lu Zhen had bought, she took out the truck she had rented when she went to sell her car at the dealership.
The truck was big enough to carry many supplies and won't raise suspicions. So, she took out the truck from her space. She was glad she had decided to keep it at the last moment.
At first, she had thought that having the vehicles bought from the dealership store and Lu Zhen's friend was enough. But she later thought that there was no useless resource in the apocalypse, so she also took the truck as a by the way.
