While Ray concentrated on his mana core and tried to refine it, Elina and Emma got to work.
With a clipboard and paper in their hands, they walked around the whole infirmary as they observed everyone first. They knew that if they walked to anyone and asked them if they were to join them, no one would deny and most would only do so to get closer to them or if they had any ulterior motives.
Also, Emma and Elina couldn't be too sure if the persona was speaking the truth or lying. Some might just lie about being good at something just so they could get out of a bad situation.
Therefore, they shortlisted those who matched their criteria and observed them to see how their attitude was. No one wanted some petty individuals running around in their them, trying to look for self benefits. They wanted those who wouldn't mind teamwork and would contribute equally, no matter what the problem presented to them.
