Vengeance

They frowned and entered the gate, with Rowan leading the way. At his level, although he could get injured, these people's guns would not kill him.

And because the estate was so huge and there were no shots fired in the fence, the people were completely unaware of their arrival, making the trip relatively easier than anticipated at least at first.

However, as they entered further, a disgusting stench attacked their nostrils. It smelled dirty and pungent. It made their eyes twitch.

Suddenly, Rowan pulled back the person next to him.

"Watch out!" He yelled, throwing a fireball at a direction, followed by a toe-curling scream.

The man screamed as he was burned alive. 

When the killing prohibition was implemented, it was only applied to areas outside the estate, as ordered by Higson in exchange for a week's worth of medicine. It was the reason why there were so many corpses.
