The day after Albert gave me the task, I asked for leave from Dean. Both for the magic college and for the medical school. I told him that Sara might be able to teach a little about air element in case he wanted to learn more or there are some students who are interested, and also I told him that Sophie should be able to teach a little bit of medical knowledge from the future that I have taught her. That way, they can learn something before I return.
I will still occasionally return by using portal, but since the mission is too important, I won't do any teaching for a while. It's better to focus on one thing first.
The nobles who visited me last night were hurriedly return back to their home. From what I heard from Sonia who eavesdropped on them while being invisible, it seems like they won't cause any trouble. They just hide their wealth before Albert arrive with the decree. As for their fate, I let Albert decide it.
