Eva's Solution, Tria's Body Expansion Skill

Inside the Beast Tattoo, Eva immediately started cultivating. She no longer cared about the outside as she focused herself on the matter at hand. 

Ban told her and Tria earlier about his current predicament of being unable to absorb essence until he completed the mission or until he cured his damaged spine and Energy Core. 

Knowing that, Eva would naturally not sit still and just leave things as it was. She was fully aware of her title, 'First Mate', which allowed Ban to raise his level directly, if Eva somehow managed to surpass him. 

Her plan was simple, cultivate diligently and help raise Ban's level by raising her own. 

Just as Ban instructed, Eva cultivated in an area far away from the Unknown Egg. After all, even though it has already become his contracted Beast, Ban was still afraid that something might go awry. He also instructed Eva that if she felt that something was amiss, she was to inform her directly using their connection.
