Elder Benedict saw the array on Grey's arms, and when he saw the fire snake, he couldn't help but take in a deep breath. This was the special ability of the Lyttelton Family, and it was recently made known that Grey's mother is a genius from the Lyttelton Family, hence the reason he was taken there to master this technique. Everyone knew of his abilities as an Inscriber a long time ago since he always uses his inscriptions when fighting. Now that he has gone to level up the ability of his inscribing, it's unimaginable how powerful he would be now.
Elder Benedict didn't panic, he had fought with someone from the Lyttelton Family years ago, so this wasn't the first time he was seeing this. The reaction of the crowd didn't bother him, rather, he prepared for the incoming attack.
Grey using this from the start shows how seriously he took this match.
