Sam and his group begin to come out from the Dungeon. It has already been 10 days since they came inside the Dungeon. In these 10 days, Sam helps everyone except his teacher to fight those Monsters.
You have to say that during these 10 days, everyone can improve themselves and also get familiar with their new power and new techniques. They are already able to stabilize themselves. All of them have a better understanding of their strengths.
Jeni and the others were also able to improve their strength during these 10 days even without observing any crystals. They are very close to breaking through to the next grade. You have to say that under the pressure of an S-grade dungeon and those monsters, all of them will improve.
