There were no more missions that people at Mikhail's level could handle.
Not because Mikhail had done them all in record time or something ridiculously outrageous like that. But simply because there were other people besides Mikhail at that level.
And as such… There was nothing more for him to do in regards to the missions. Not until the caravan's next stop, anyway. Unless, of course, he decided to go get that spider or the juvenile Basilosaurs from before.
And while the Basilosaurs were too large to even consider…
That spider was another story.
It was big, sure… But it was far more manageable. In comparison, anyway. Something that Mikhail could do easily before the next three hours passed.
Thus, he went back to that cave network yet again. There was no time to waste, after all.
However, when Mikhail arrived, he noticed something odd.
