"What are they?"
Nodding her head, Rias didn't answer and got in the bed as well and made Natsu place his head on her lap, only after which she began speaking.
Sighing from how Rias was behaving, while feeling a little happy that she hadn't given up on him, Natsu felt that it wasn't right of him to project his negative emotions on Rias.
"A Dungeon Master cannot manage multiple Dungeons at all times, and also needs some help in performing his duties correctly. That's why, they are allowed to grant one of the two classes to any adventurer, monster, or anyone else of their choosing."
"Anyone who is given the Proxy Dungeon Master Class, can control the Dungeon you allot them. And, to make sure that they don't abuse their powers, or work as spies for others, you can even place restrictions on them."
"These restrictions are of many kinds, and can limit the chosen Proxy Dungeon Master from leaving the Dungeon, not reveal any information regarding the Dungeon to the outside world, check through with me before purchasing anything from the Dungeon Shop, and so on."
As Natsu continued nodding his head, Rias began explaining about the second class.
"The Personal Assistant Class, on the other hand, gives the one you choose much more authority and power. So much, that if you choose a Personal Assistant hastily, it can easily lead you and your Dungeons to an end."
Hearing those words a serious expression formed on Natsu's face, as he asked, "What powers does a Personal Assistant have?"
"As the name implies, the Personal Assistant is someone who works directly under the Dungeon Master. And therefore, they have the second highest authority inside all of your Dungeons, after you."
A little surprised, Natsu looked towards Rias.
"Even higher than you?"
Shaking her head, Rias said, "I have zero authority, darling. Without being ordered by you, I can't even command a single Dungeon Monster."
"That means, you have the same authority level as me."
Smiling happy from realizing how Natsu's thoughts were, Rias didn't day anything and started running her fingers through his hair and began explaining the other details related to the two classes.
It took around two hours for Rias to explain every single detail related to the two classes, but by the end, Natsu no longer had any signs of his previous disappointment which made Rias feel that her effort was worth it.
"Hey Rias, do you think... I'm emotionally immature and don't share my feelings?"
"Yes."
Being answered so swiftly, and without the slightest hesitation, Natsu was about to sink into disappointment when Rias continued speaking.
"However, that's quite understandable. After all, I don't know how your life before this was, but adapting yourself to your new life as a Dungeon Master, even if you haven't realized it yet, it does cause a lot of stress for your mind and body."
"Also, you might never have had to deal with any kind of such stress until now, due to which you don't know how to deal with it."
"But, in time I'm sure that you'll be able to open up and find yourself in a state where you can deal with all of those emotions in a safe way."
"And, I'm more than happy to wait for that day to come, when you will be ready to share your true feelings with me."
Not saying anything, Natsu turned over and began thinking about what Rias and the mysterious voice said.
After all, even if he did want to change, it wasn't something which could be done instantly.
Smiling a little, Rias didn't say anything and continued to brush Natsu's hair with her fingers as he kept on thinking and completely forgot about having to buy monsters for the second Dungeon.
"Ah! Rias, what is the Fire Dragon Queen's Egg?"
"The Fire Dragon Race is one of the strongest combat type Races in the universe. And a Queen of from that Race represents the epitome of power."
Pausing for a while to gather her thoughts, Rias continued to explain.
"Usually one can only buy ordinary Fire Dragons from the Dungeon Shop, but that too can only be done in the higher levels, and costs a lot of points."
"The Fire Dragon King or Queen, on the other hand, can only be obtained in the form of an egg, which grows along with the Dungeon you bind them to."
"In short, the reason I told darling that you were lucky to obtain this egg was because your Dungeon is still only Lvl 1, and by the time its level increases, your Fire Dragon Queen will always be stronger than any egg type beasts you encounter who share the same Dungeon Lvl as your own."
"I see. So there are other similar beasts?"
"Indeed, darling. Other than the Fire Dragon King and Queen, there are many more such beasts which can be obtained in the form of egg and then incubated."
Nodding his head from how real life Dungeon management was harder and more complicated than he always thought be, Natsu asked Rias on how to bind the Fire Dragon Queen's Egg he had with him.
"It's very simple, darling. You only need to place it on top of the Dungeon Core, and it will continue growing along with the increase in the Dungeons Lvl."
Getting up, Natsu moved to the far end of the Dungeon where the Dungeon Core was floating at, and took out the Fire Dragon Queen's Egg from his inventory.
Holding the huge egg which was bigger and heavier than expected, Natsu almost fell to the floor, but managed to hold it and not fall.
"Sigh... "
Sighing from relief, Natsu lifted the big coloured red egg which weighed around 30 kgs, and barely managed to place it on top of the Dungeon Core.
Once he did so, Natsu took a step back and wiped the sweat off his brows as the Dungeon Core started to change.
