A few days later...
So, clearing the first trial took Muku a lot more time than he thought. The floors kept on getting more and more absurd, the more he cleared.
The sixth floor had fifty killer dogs. The fifth had a hundred. Both floors required him to run all over the place before he managed to clear them. If he didn't have access to the floors he had already cleared. He would have been screwed for real.
Fortunately, the physical improvements from all the killer dogs he killed were worth it. He was on par with them in strength by the time he was half done with the fifth floor.
Then came the fourth floor. Things got switched up again. Mrs C really knew how to keep him on his toes.
Just when he starts to get comfortable with the system. She changed it every time. And that was the case with the fourth floor. Instead of adding more killer dogs. Which would have made it rather hard for them to even properly fight.
