When Jason emerged on the 20th floor, he felt a little bit weird.
The beasts' strength was much higher than that of the beast only one floor before, but even then he had no problem defeating them.
Instead, it was rather easy for him, and the amount of strength he had to use was low in comparison to before, which caused him to feel a little bit dumbfounded.
'I thought the cultivation base would increase drastically every 10th floor...did I expect too much, or did I increase my strength to a very high degree?'
The latter was not possible because one could never be too strong.
Furthermore, Jason had yet to reach the 2nd threshold of the Prismar stage. Each of his characteristics might be exceeding the 1st threshold of the Prismar stage, but, in the end, he had only solidified four prismarine crystals so far!
