What Noah did wasn't for the benefit of the mission.
He had revealed their position, killing only two injured soldiers, the surprise effect could be considered wasted.
Yet, he would rather do that then charge alone on the enemies, hoping for the group behind him to follow.
'If they think like me, they will use me to identify their abilities and then charge. I won't risk my life for them.'
He had already obtained the reward for the mission, he couldn't care less if it was to fail because he was unwilling to risk his life.
'Also, if the Royals really cared about this matter, they would have acted personally.'
Noah didn't believe that his group was the only force deployed for that task.
He knew that the Royals had spies set up after all so there was a high chance that there could be hidden troops too.
The soldiers from the Muwlos family reacted quickly and set up a battle formation around Samuel with their bodies turned toward the now exposed cave.
