In truth, Lux was happy that Nero destroyed the artifact on his chest because this was something that he didn't want others to see. As a Necromancer, everyone thought that they could easily take them out if they managed to isolate him away from his Summons.
What they didn't know was that Lux was just as deadly as his Summons because he wasn't a frail mage that would die just because someone punched him in the gut.
Even now, Lux's regeneration abilities were doing wonders to his body since the opponent he was facing had a higher rank than him.
Nero couldn't believe that, since his Rank was higher than Lux's, the latter was able to last longer than him.
"You still want to continue?" Lux asked in a teasing tone. "I can do this all day."
Although the Half-Elf was smiling, his body was wracked with pain. However, seeing the disbelief on Nero's face was enough for him to break into a smile despite his suffering.
