Noah threw more resources in his bait to lure out the peak rank 6 specimen, but the creature didn't leave its lands. The lower tier specimens were the same, and that left him out of options.
That was the limit of the safe approach. Noah had only managed to kill three specimens before the real battle. Noah didn't know if the world could withstand it, but he would do his best to avoid any unnecessary attack.
'The weaker creatures will surely jump into the battle once I start fighting their leader,' Noah thought as he resurfaced and stored his bait. 'I can only take care of them first if I want to avoid useless shockwaves.'
The lower tier creatures didn't even modify their patrol after the death of the middle tier Snakes. Noah knew where they were, which allowed him to create a strategy that could limit the damages on the world.
