Originally, Zain never planned to go back into the club unless he saw others enter. Possibly the ones that were giving orders to Shark and Kun. However, due to certain circumstances, Zain was unable to keep a close eye on the club, and now after waking up, it was clear that something had happened.
In the end, now that the sun had fully risen, Zain had decided to head back there. He looked outside of the building and the area around it slowly to see if there was anything he could spot.
Any signs of the others leaving or anything strange occurring, and that's when he realized he found nothing.
'This is really strange, there is absolutely nothing within five hundred meters from the club.' Zain thought. 'Not a single dead body on the ground or a zombie just treading its feet along. Was it the military that arrived here and cleaned it up, or was it the other group?'
