I left the saint in charge of the students with very clear instructions not to help them beyond small hints or if they were truly in danger. I had to get away because of the adventurers.
I hate to admit it, but I underestimated that S-Rank team, and they ended up going where they shouldn't. They're entering the underground, and I know this because the monster down there has been agitated by something "invading" its home.
And if I don't do anything, that monster might come to the surface and ruin my fun, since if an S-Class monster appears, the training would obviously have to end.
So, after separating from them, I quickly started looking for that unfortunate group, who are more efficient than expected. They have great artifacts or spells to hide, as it's not easy to notice them.
