Six months passed by like they were nothing.
The players spent all of their time in Hell. Killing the creatures that are manifested from their own sins of the past.
Sam is getting used to facing them more and more and he also got used to finding out what kind of powers they might have and what kind of weaknesses will tag along with those powers. He can easily take care of most of the opponents and for the free tricky ones, he started having much easier time that he is supposed to.
Hel who is spectating all of this, obviously didn't like it.
But she didn't do anything. There are not abrupt increases in difficulty and there are no extra obstacles are placed in front of him.
He just went through the training and he cleared floors at a rapid pace. While the other players just crossed a benchmark of fifteen floors, Sam is already at his twenty-third.
