After coming back to the house Allen already thought about going inside of the dungeon. As you know that he already used his system to go inside of the Dungeon the previous day and because of this, you will once again go inside of the Dungeon today.
Also tomorrow is the hunt and because of this he wants to prepare himself to face those monsters. Actually today he will face those monsters without using his bloodline power.
As you know, right now nobody could tell how powerful monsters they will face inside of virtual reality but one thing was clear: those monsters could be powerful and could easily kill him. It could also happen that even after using his bloodline power he won't be able to kill those Monsters and because of this, today he wanted to face those Monsters without using his bloodline power.
