Alexa managed to slay a single Green Orc. Despite that, she was not looked satisfied after witnessing Kai kill the same monsters in under a minute. Well, she was simply aware that before he could do the same thing, she have to train her body to its limit.
On the other hand, Kai was well informed what was the meaning of that facial expression on her face. Yes, showing his outstanding skills and abilities might affect the morale of the others, but Alexa was quite different since she was using that as a motivation.
'I worried for nothing. Alexa is a tough woman, I should not always look at her as a baby.' He uttered to his mind, then seize the monster's cores so that they could continue their expedition.
Soon, Alexa went to Kai's location and gave the core that came from the monster she killed. "Here, Kai. Hide it inside your spatial magic." She said in a polite tone.
