A few days later;
In the city of Shengzen, currently swarmed by the zombies, four injured teenagers with baseball bats in their hands and a bunch of Molotov cocktails in their backpacks were taking a rest in a dark alley and administering their wounds.
There are several reasons as to why they didn't choose to rest in the house.
First of all, this was merely a short break.
Secondly, staying at a house was risky as it would restrict one's movements if a horde of zombies suddenly swarmed inside. They want to keep their escape paths more open.
Thirdly, because most of the residences are made of wood, throwing a Molotov cocktail to save themselves will only hurt them in the end.
Last but not least, they cannot just barge inside a house without knowing whether there are zombies lurking in it or not.
Hence, they decided to hide in dark alleys as they hoped to exit the city through the ships.
