After having their late lunch, even though Treyton gave them time to rest, the members didn't fully rest but still practiced on their own.
As for Luciel, he also didn't go outside to continue killing zombies, but unlike the others, he just started playing and then went to sleep afterwards.
The next day, they continued dealing with the zombies outside. They started cleaning up the zombies around the building that they were staying at and then continuously moved outwards.
In the next six days, they managed to clean up 500 meters away from the building that they were staying in, in a circular manner with the building they were staying at as the center.
Of course, the area that they had cleaned up was actually wider than 500 meters, but a lot of zombies would still come back to the areas that they had already cleaned.
He only considered the 500 meters because those were the areas where very few zombies were wandering around after their daily cleanup.
