Power Growth.

(You know, I might write an Omake chapter about a fight between Maulketh and Kurayami at the end of their journeys for fun. And no, those two will never meet as I would need to pick one over the other as they would never be happy to share the same Harem members.)

Maulketh patiently waited as Tiamat, Calypso, Athena, Ingvild, Valina, and Runeas absorbed the tidal waves of Conceptual, Soul, and Vital Energy. Just from here, he could tell that the 6 of them were undergoing extreme changes.

In his opinion, he was witnessing the birth of 6 goddesses. Well, Athena and Calypso were already a goddess and Titanness, so more like 4 new goddesses. How could he not be proud?

Now he just had to help Rias, Akeno, Kuroka, Shirone, and Kimmi. But in all honesty, Rias did not need much help. She had his bloodline and she was constantly training with Runeas. Akeno was similar as she too had a powerful bloodline from her father Baraqiel.

Kuroka and Shirone were also extremely talented Nekushou, so they would not need much help from him. Meaning, only Kimmi would need a bit more work from him. He thought of what to do for just a few moments.

As he was thinking, Ophis and Trihexa walked over and stood next to him.

Considering they were Dragon Goddesses, they considered themselves to have higher status than his other lovers. As he was a male Dragon God, he also agreed as they were much stronger than his other lovers. And they were connected to him through their Concepts, a stronger bond than he could explain.

He cleared his mind as he knew what to do.

"Alright, first of all, you all use Demonic Power in some way or form as most of you are part Devil. Rias, you have my bloodline in you, so you are better suited for a mixture of Infernity, and Divine Dragon Energy, leaning more to the Infernity side.

Kimmi, you are going to use a balance of Infernity and Divinity as that will suit you best. Akeno, you are better suited for a Balance for Divine and Infernity as you are a hybrid of a Fallen Angel with a Devil Bloodline through your Queen Piece. Shirone, Kuroka, you two are going to have pure Infernity as you two use your Nekushou sides more. Now to start on this.'

In front of Maulketh, 5 orbs of energy were gathering. He was refining his own energies into 5 perfect catalysts to start the changes to the 5 of them. As he did this, Kimmi spoke up as she was curious about something.

"So, if our energies become that of gods, would we be considered gods?"

He shook his head.

"No, you are all still 'mortals'. Me helping you to gain godly energies, would be more like you all would be more like demigods. To become gods of any kind, all of you have to form your own Divine Spark which will represent you.

Once your Divine Spark is strong enough, it will fuse with you turning you into gods. But that will just be one of a long journey that you will follow me on. Because I will not stop in my journey until no being can face me."

Rias spoke up.

"Do you have any idea how to form a Divine Spark?"

He actually did know how, just that he never formed his own. His Divine Spark represented his Principle at the time as he had stolen the Divinities of Zeus, Hermes, and Kronus to form.

It then evolved into a Concept when he became a Dragon God.

"First of all, you will need a Symbol of Power which you will all get. Once you get this, you will need to learn who you are as an individual and slowly form your Spark. From there, you will need to nurture your Divine Spark until it fuses with you and you ascend into a god. Now hold still."

Finally finished, the 5 orbs floating in front of him surged into the chests of the 5 of them. Ophis and Trihexa looked at the process as it was interesting to see. Through their bond, Ophis got a quick understanding of what he was doing.

"I see. Those orbs will begin to change their bodies to begin to run on the higher rank energy than Demonic Power."

He nodded.

"Exactly. Now, all you 5 got to do is wait a day and the process will be finished."

Rias placed a hand over her plump chest as she felt that small ball of energy next to her Dragon Heart draining her Demonic Power before spitting it out as Difernity(A mash-up of the words Infernity and Divinity.) Just the small bit immediately was absorbed by her heart which slowly, but surely would begin to warp her heart to not produce Demonic Power, but Difernity.

She was the only one with a Dragon Heart, so the rest would just evolve their bodies and bloodlines through this energy.

"There. The process has started and you just need to wait. Of course, training also helps."

The moment he said that they rushed off on their own to get started. He smiled as he liked the hard-working ethic that he had instilled in all of them. Knowing how to form powerful Time Formations was probably his strongest cheat as he could compress hundreds of years of training into just a few days.

Just as he was deep in thought Trihexa spoke up.

"You know if you have sex with them they will also get stronger?"

'Oh yeah. There is that.'

Ophis knew why.

"Oh yeah, those Chinese gods called it Duel Cultivation. Apparently, the male will refine the female's energies and fuse them with his own. Considering we Dragon gods are just Concepts given form, it stands to reason that we would be quite good at it."

That reminded him of something.

"Trihexa, were we doing that?"

Trihexa remembered when they were mating. Every time he came inside of her, his cum, was coming in contact with her own Sex juices which were produced by their body's Conceptual Energy. That was why they grew so strong after all the sex.

"Yeah. We pretty much were."

Ophis smirked.

"When can I get my turn?"

He smirked back.

"Soon, It was pretty useful in growing stronger. But I think the way we were doing it was different as it was just an accident."

Ophis pulled out a book from somewhere and handed it over to him. He looked at the cover which was in Ancient Mandarin which he could understand. It said 'The Secret Art of Duel Cultivation by Zhan Xiang.'

"Where did you get this?"

"When you sent me and Trihexa to 'bring order' the hidden Chinese clans under the Chinese gods came out and pretty much surrendered along with the gods. Their magic system is called Cultivation and they called Mana the 'Energies of Heaven and Earth'. And they used that to grow stronger."

Maulketh sped read through the book and he had to say that Zhan Xiang was a genius. Apparently, in his life, Zhan Xiang was an extremely handsome young man of the Xiang clan. He was talented to the extreme, and he was blessed by The Jade Emperor. The god-king of the Chinese gods.

But, while his family tried to get him to train to use his talent and blessing, he preferred to have sex with beautiful women, regardless of species. And through his talent, he created 'Duel Cultivation' the method to grow stronger by doing what he loved. Having sex.

(Great, now I got attached to Zhan Xiang who I made up on the spot. I got to write an original story about him someday.)

And according to this book, he created a huge harem of many species and races. But the book did have a fun line at the end.

'I have recently reached a new Cultivation Realm. My time in this world has ended. I am off to search for beauties through out the cosmos to give expand my harem of Peerless beauties. Guess I will leave this book to my family. Maybe they will use it? Should they get over their brain-damaged ways I guess.'

Maulketh chuckled and out of curiosity spread out his Domain throughout the world, but he did not find a single thing about him. He did see the Xiang clan, but that was it.

'Guess he did leave. Wonder where?'

He ignored that as he got the jist of what Duel Cultivation was. It was more than just having sex, he had to refine his energy or the other way around with his partners through sex. It would be a useful thing to use the next time he had sex with his harem.

Which was going to be soon as he was dying to touch them again.

"Ok, this is going to get used in the beddroom."

Ophis smiled at him.

"And when will that be?"

He saw the 6 tornadoes of energy, Astrid, and Celestine evolving, and Rias, Akeno, Kuroka, Shirone, and Kimmi training like hell. He quickly calculated when they would all be finished and came up with an answer.

"3 days."

Ophis and Trihexa licked their lips as they looked at him like he was a piece of meat.

"Can't wait."

Trihexa could agree with Ophis on that.

"Trust me, once you fuck him, you won't ever want to stop.

Ophis' legs clenched as she started to devour Maulketh's giant muscular form in all its glory.

"I can bet."

To distract them, he returned to his Dragon Form which instantly caused a massive tidal wave of energy. He was 1,000 meters tall, and he was even longer as his long tail waved behind him. He thought that would calm the two, but instead, it seemed that Ophis was turning even hornier.

Even Trihexa was feeling a bit frisky when she saw his true form. She licked her lips as she wondered if he would be up to sex in their true forms. But for now, she and Ophis took in his sexy form(To them).

His size was the first thing they could see as everyone else usually did. But they looked closer at him. On his chest, burned bright the Symbol of the Spartans, glowing gold with a black outline.

On his left wrist was a giant Blood Red Zero which was the Blessing of Great Red. On his right wrist was the Symbol of Shiva showing the close friendship the two shared. On his back was a giant violet Infinity sign, the blessing Ophis had given him.

His entire body from his head to his tail was encased in a dark suit of living metal that flowed with his Concept as it was constantly purified and strengthed. Under that armor was a second layer, of scales. The same as his armor as they were constantly purified to become stronger, tougher, and more adapted.

His back was covered in large spikes that erupted from his armor, he stood on 4 legs each tipped with giant claws that could slice through any being. His mouth was tipped with huge razor-sharp teeth that could cut, slice, and crush.

His tail ended in a massive bladed end. Noticing how much attention they were throwing him he began to give them some possession to show himself off. The more he did, the more they seemed to go into heat.

He could literally smell the arousal from both of them. He could tell he was also drawing the eyes of Rias, who was also a partial dragon so she was feeling similar feeling to Trihexa and Ophis.

Just as he was having some fun with his mates, he felt a distinct feeling from his soul. Astrid and Celestine had just broken free of their evolutions and were ready to be released. It was about time as they seemingly stayed longer than normal.

Time to set them loose and see what they had changed into.
