As the thoughts of the Archer class cadets and Sniper class cadets went astray, thinking that the blue box around Elena was practically indestructible with no chance of breaking it down, Gary was heaving a sigh of relief due to the condition he was in.
Having to focus on Elena, using his tachyon energy reserve in his core to continually reinforce the blue box to ensure that Elena would remain safe no matter what attacks come her way.
This took not only physical power but also mental and physiological power as well, leaving Gary almost completely drained by the time they had finally stopped bombarding the blue box around Elena, an end that he was extremely grateful for.
He was at his limit as his sweat pores so generously went ahead to open the flood gates, ensuring that Gary was bathed in a cold sweat that caused him to feel slightly uncomfortable, of course, he couldn't dwell too much on that seeing as they were still in dire straits.
