Sam was now looking at the message that he suddenly got from the warrior association. Well it was a message for re-examination. He needed to re-examine or he won't be able to participate in the match. Well it seems really they already found out his grade. Sam just sighs. He just really wanted to hide his strength and then enjoy the fight. Who could have thought that something like that would happen.
At the end, Sam decided to forfeit from the competition. He knows that even if he goes to the reexamination, then he won't be able to hide his strength, he needs to show his peak D-grade power. Because previously when he was very low on spiritual energy his concealment technique got deactivated and most likely because of this everyone was able to feel his power.
With that thought he decided not to participate in the match. So he informed the warrior association that he would like to forfeit from this competition.
