Finally both Zero and Lucas go toward the last floor to face the Boss monster. It has been 2 days since they came to the third floor and were hunting those Monsters near the entrance of the next floor.
All the time they would maintain a minimum distance from the entrance so that they could observe if anyone entered the entrance or not. Fortunately, it looks like in these 2 days nobody enters the next floor to hunt the Boss monster and this is a very good thing for both of them.
Naturally, they could wait a few more days to gain more exp, unfortunately, if they did that then there could be a chance that some other group of guardians went to the next floor to hand the Boss monster.
With this, both of them did not want to waste any more time and were already going toward the next floor. While both of them walk down following those stairs both of them can feel the excitement.
