The night of battles wasn't over yet. It felt like the sun itself didn't want to show it's face to the earth. What would've been a few hours, felt like aeons. But finally, the attackers were losing the fight. Their guerilla war tactics were only so much effective against their enemies.
Once Arnold's summons took over the battleground, it was an all-out massacre. The
Brazilian's plans were full of holes.
First, they had assumed there won't be any warriors above the S rank, which proved out to be wrong. Johnny was still there. More than willing to kick their crap out of their bodies.
Secondly, they failed to retrieve a proper map of the estate. There were a lot of places for people to hide and thus even though a few of the people died, most of the non-combatants were safe. Something the attackers were only realising now.
