Luckily, a few bedrooms were spared, and currently Hisau Maiya was resting in one of them. Although Irisviel had already performed healing magecraft on her, the Einzbern healing magecraft is an extremely large burden to the wounded after all. This is because it is adopted from alchemy and does not cause
the injured body to regenerate, but use magecraft to create new tissue and use that for grafting.
That was the only thing she could do for now. It wouldn’t matter if the patient is a homunculus, but since she was healing humans it would count as a major operation similar to an organ transplant in modern medicine.
