"You can understand that?" Aya asked in surprise.
She knew how to read and speak, which is why she found it amazing that Hiroki was also able to understand this ancient script written in this dungeon.
"Yes...."
Hiroki confidently said before continuing his sentence in his own mind.
'After all, I used to play around with basic programming...'
After a few more minutes of trying to decode all of the zeros and ones that were carved into the wall, Hiroki finally let out a sigh after gathering all of the necessary words written on the wall.
'So this wasn't a special mission for the ones who had been summoned.' Hiroki concluded in his head while his eyes narrowed at the realization.
The binary code wasn't overly complex to decipher, especially for someone with basic knowledge of it. However, one question still lingered in his mind.
If their purpose was to allow rare summoners to enter this wall, wouldn't they all need to have the necessary knowledge of basic programming?
'Unless... this part of the dungeon wasn't meant for them. But to be more exact... the one who created it.'
This also proved to Hiroki that, in order to use magic and status in this world, they also used programming from the modern world in a way to apply a useful system to the user.
"Hiroki, did you figure something out?"
Aya asked after seeing the concentrated yet eager face of the quiet ghost that was staring at the weird ancient writings. She didn't want to bother him with unnecessary questions, which is why she tried to give her best in order to assist him.
"Yes, but I want to confirm something first. Do you know what a Dungeon Master is?"
"A dungeon master? Do you mean a title like 'Slave Master'?" Aya confusedly asked.
"Yes, a person who owns and controls the whole dungeon. Does something like that exist?"
If he was right, then what might be behind this wall would be the main place where the one responsible for the appearance of this dungeon is. Also known as the 'Dungeon Master'.
"That is…."
Aya fell into her own thoughts, as she had never thought or heard anything about a being that could control a dungeon at his own will. She wasn't a veteran adventurer, but she had been on quite a lot of quests and in places where she would have had to risk her life, and until now she had never heard something like this.
"....Impossible, right?" Hiroki responded to Aya's innocent look of ignorance before showing a slight smile.
But when Aya looked up at him, she saw how twisted his smile was, which showed a cunning mind. She was already aware of what kind of person her benefactor was, and she was proud of it. But this side of him, no matter how many times she has seen it, still gives her a slight shiver on her back.
"Then, let's find out for ourselves." Hiroki suggested as he approached the wall much closer with the possessed body of one of the adventurers that couldn't escape his grasp.
"....But how do we?"
Aya asked innocently, perplexed by the lack of any visible path or entrance on the solid rock wall, which appeared thicker and more impenetrable than it seemed.
However, her eyes widened in shock when Hiroki drew out the adventurer's sword and pointed the tip of it at his own throat.
"....."
Aya understood what was going on. And despite knowing the feeling of killing someone else, she still couldn't understand or feel at ease about this suicidal thing that Hiroki was attempting with that human body.
Her eyes, which were growing colder, looked at the brown-haired adventurer before hearing his whining noises of resistance.
"...P-please…. D-don't…k-k-kill m-m-m-mee!"
The adventurer struggled to speak as he used all of his strength to prevent the ghost inside him from thrusting his own sword against his throat.
Aya's hands twitched for a moment before she closed her eyes and looked to her side.
".....I'm b-b-begging you….. I h-h-have a…. S-sister w-wa-waiting for m-me....."
But before the adventurer could finish begging for his life, a sword sliced open his throat, preventing him from speaking and immediately ending his life within a few seconds.
