The second floor challenge was a whole lot harder than the first floor challenge. But, somehow, Kelvin, Jim, and Nicole, were able to successfully complete the said challenge.
Though, as a result, they sustained a lot of grave injuries. So, just like before, the three of them decided to rest, while receiving the healings from Iris' healing light.
And just like that, the three of them continued to follow the same cycle of resting, and then completing the next challenge with deep grievous injuries, and then back to resting again. Though this cycle slowed down their progress, it still gave them a chance to survive at least.
Thus, they slowly, but surely continued their ascent in the king’s tower. However, things took a wild unexpected turn, when they reached the tenth floor.
