At some point, Calina and Luina finally gave up and focused on their tasks. As Rean mentioned, Roan continued to give Luina a few pieces of advice here and there. Sometimes he would fight Luina to show her points he deemed to be important. Of course, he wasn't the only one. Rean also fought with her a few times. After all, he wasn't much weaker when compared to Roan.
Roan also included Malaka and Calina in these training sessions. He was going to do it anyway, so he might as well put everyone to work. However, it was the fight between Calina and Luina that was the most intense. Unfortunately for Luina, Calina was still a princess of the Empire with top cultivation techniques and skills. Because of that, she was beaten up quite badly.
'Just who is this Illia? I have close to no chance against her. If it was a real life and death battle, I would only be able to flee. Only sneak attacks have some effect on her. But even that doesn't make that much of a difference.'
