Cap 623: Ambush at the start of the trip
Their ambush had several layers of strategy to prevent it from failing, they set up magic traps in the air waiting for us to pass this route, and they used poison they must have spread around the surroundings a long time ago, plus this poison is strong enough to kill someone of the Grade SSS, also used 10 powerful people as bait to draw our attention in a direction as if to start a head-to-head battle, but that was a distraction to open up an opportunity to attack from behind with those dozen fire ray spells.
I don't even do anything, I had already noticed these spells being activated by someone else in the back, so I stayed a little further back.
When the fire ray spells hit me it didn't do anything to me, these spells have a power to kill someone of Grade SSS, maybe even hurt someone of Lower Catastrophe Grade.
