Cecile was finally completely unable even though she was bracing herself over and over again, she had felt so tired and to just breathe it felt so hard. After she made her Mana divided on the sick people.
People probably viewed what Cecile did as an extraordinary act and looked very easy, just holding her could cure the disease that put their lives at risk.
So, naturally they didn't notice it. Because no one asked her that. They seemed to assume that he had no limit at all.
Her body felt so tired with bones that he felt so miserable and wanted to rest. Actually, she could reach the magic circle five as well by swallowing a lot of Mana stones forced on her, her body felt shattered at that moment. The coercion made his body experience the pressure of the alley so much, a thing that really shouldn't be done. It seems so arbitrary and of course it has a deleterious effect.
