When they finally found one, it was already 15 minutes after the rain had started.
After the others checked that the building was really usable, they immediately cleaned up the second floor that they had opened and entered right away.
The entire first floor was also flooded, so they had no choice but to make their own door and enter the second floor, as the fire exit was on the other side.
After everyone entered, the others went to clean up the higher floors as fast as they could.
The building they were in had only six floors and apparently had a low number of zombies, so they immediately cleaned it up.
But the building was obviously an office building, so it was harder for Nina and the others to clean up all the things to make a space for all of them.
So, they prioritized cleaning up all the rooms with bathrooms or close to bathrooms so that everyone could clean themselves first, as most of them were wet because of the rain.
