All in all, Natsu had spent a total of 125,000 DP to just remodel his Dungeon. And now he would have to spend even more to fill it with monsters.

Luckily, even though the Dungeon was much bigger and would need many more monsters to fill it, due to the maze and the various tunnels which made it impossible for everyone to walk in the same route, when intruders entered this Dungeon, it would no longer guarantee that they would have to kill all the monsters to make their way through the Dungeon.

Due to this, the number of monsters would be spread out, and could launch true guerrilla warfare attacks.

Also, even if a party was able to pass the ground floor and enter the first floor, they would not have killed all of the monsters on the ground floor, allowing Natsu to not spend too much DP every time someone managed to enter the first floor.

At the same time, Natsu decided to fill each floor with a single, or maybe two types of monsters.

The ground floor would be for the Goblins and Kobolds, and the first floor would be for Orcs.

This was so that the intruders wouldn't feel too scared after just entering the Dungeon it, which might want to make them run away.

And after the completion of the Dungeon remodelling, Natsu spent another 10,000 DP to create three rooms, which included one bedroom, a kitchen/dining, and a bathroom.

With this, Natsu had spent almost all of the bonus DP he obtained, and was left with just 25,393 DP.

But, Natsu didn't regret spending a single one of his DP, since he wouldn't need to invest anymore DP to change his Dungeon until it reached Lvl 2.

Not that he could, since to add one more floor, his Dungeon needed to be at Lvl 2.

At the same time, now that Natsu's Dungeon was much bigger, he felt that now was the best time to create a maid to look after this place.

Not because Carla's work was sloppy, or bad. But, because Natsu had always wanted a maid.

Originally, Natsu had the idea of creating Akeno, Grayfia and the other beautiful women from Highschool Dxd and make them the Dungeon Cores which would provide him with a collection of every woman from the same series.

However, Rias destroyed this dream of Natsu by informing him that he could only have one Dungeon Core interface for all of his Dungeons.

And since he had already chosen Rias, he could no longer create another woman or substitute Rias for someone else.

After saying that, Rias actually broke down and started sobbing by saying she was sorry for being so useless and forcing Natsu to have thoughts of creating a second Dungeon Core Interface.

Luckily, Natsu didn't just stare at her like an idiot and consoled her saying that he couldn't have asked for a better woman than Rias, and he would never change her, or let go of her.

In fact, it was after Rias calmed down, that she kissed Natsu by surprise and ran away after saying thank you.

Well, there was no problem, since Natsu had already found another way to create all the women he wanted, without having to sacrifice his Personal Guard's beauty over her strength.

And it was through purchasing a maid from the DH System.

When he would do this, the DH System would ask if he wants a random maid given to him, or if he wants to create his own.

This way, not only would Natsu be able to turn all women he fantasized about into a reality, but even have a maid like he always dreamed for.

The only limitation was that he could only have one maid per every Dungeon.

Not hesitating at all, Natsu spent 1,000 more DP to have a maid personally made for him.

Also, the only reason it cost so much to make a maid who would never take part in any combat, was because the DH System needed to make a special conscious for it.

If not, it probably would even cost 100 DP to make a maid.

With the perfect maid for this Dungeon, already in his mind, Natsu directly imagined her and turned her into a reality right in front of his eyes.

After all, who better to choose as a maid than Rias's own sister in law, Grayfia?

"Maid Grayfia is at your service, Master."

Nodding his head with a huge smile on his face, since he always wanted to see a real life maid. Natsu couldn't bring himself to look away even though Rias was pouting and trying to turn his face and look at her.

"Darling?..... Darling?!... DARLING!!!"

"Yes!"

Turning abruptly towards Rias whose eyes were very close to crying, Natsu failed to see the satisfied smile on the newly created Grayfia's face.

"Weren't you depressed due to what happened with that woman?"

"Oh, that? I've gotten over that already."

Turning back towards Grayfia who was obediently waiting for his order, Natsu asked, "What does a maid like you do, Grayfia?"

"I do everything and anything... That my Master asks of me."

While Grayfia's words seemed to be normal, the way she spoke them made Natsu's spine tingle with excitement as he almost rose and moved towards her.

Unfortunately, Rias held him tightly and pulled him back.

"What do you think you are doing darling?"

"Nothing... I was just... I was definitely not thinking about anything perverted."

"I am more than happy to perform anything perverted, in case you want me to, Master."

"Really?"

As Natsu asked with wide hopeful eyes, Rias finally stopped looking pitiful and coldly said, "Even I am more than happy to push the both of you inside a stream of lava, darling."

Shivering a little Natsu looked away and refused to let the situation continue, even though he knew that Rias would never do any such thing.
