After ignoring the fact that Bill was not present while the summoning had taken place. Lucas and the others went to do their work.
Things were very normal and peaceful for days on end where Lucas went out to fight creatures till he was tired which took him more than 10 hours of gruesome hunting.
This made him level up. Lucas didn't want to admit it but he had not much to do in the shelter, the one thing he was good at was fighting so he took it in his hands and went on a killing spree to make the land around the shelter much safer than before.
No one in the shelter was doing anything for the upgrades of the shelter so Lucas did that work too until he could find something important enough for him to pass the time with.
