My wife's sisters want me to make a harem?!

"Profit... Big nations don't stop wars, even if they can, due to the lucre they all can make," Minato whispered while reading articles from the far past.

He was back on Earth, his face reflecting the monitor's light.

Clicking on the mouse and scrolling nonstop, Minato filled his head with knowledge about the wards and used the history as a small foundation for his following plans.

He wanted to help Princess Julia.

She was much better than before, and even her mother regained some colors. Both of them needed to announce the king's death, which was naturally fabricated due to the tempered memories of other nobles.

It was hard, but things looked better for the royal family after that struggle.

After a few days, Julia also became the queen, and she had received the Overlord's Blessing. It was more or less official that there was something between the queen and him.

The Secret Division was named Ice Blade.

They were former maids, but most kept the same occupation and invaded deeper into the royalties' net. Of course, no one believed that those people would plan something against the current royalty, but what about the future?

Julia left spies in all royalties and kept an eye on them.

Ice Blades also trained with the Ice Trolls to become stronger and polish their abilities. One side did it for achievements while the other genuinely trained their bodies.

Frost Dwarves helped Ice Trolls at every step, be it training or teaching others. They also used their creations if need be, and it was a pretty good time overall.

All the Ice Blade Division women were important, but the hard work and rewards always worked the best. Ladies who showed the most potential and hard work received additional dual cultivation sessions with the Overlord himself.

Minato still did it with all ladies a few times, but some were lucky to have him for longer, and their dual cultivation lasted more than just a few minutes.

Continuing the progress, Minato also used Bei's schedule as a base and opened doors for the Volcano Lizards' women.

His rules were clear, and many ladies offered themselves to their new master.

Their numbers were nearly identical to the elven ladies who dual cultivated with Minato. That number started the highly competitive bed nights where elves and volcano lizards competed for their master's body.

Yes, Minato did a threesome with two unique ladies somewhat regularly now.

Elves, Volcano Lizards and Ice Blade...

At some point, other than swinging his hips and having pleasure, what else did Minato do? Pretty much nothing, so Minato escaped to Earth together with Aya.

It was impossible to think about dual cultivation with his spirit, and both of them spent casual time on Earth. As Aya slept on the bed due to exhaustion after a full day of running around shops and the city, Minato checked articles and increased his knowledge.

"One nation can't rule the whole world for eternity," Minato read the content, then sighed.

He decided to take the whole knowledge to Julia and let her look at it.

-

The Hard Steel Empire's land has been thoroughly absorbed by the Majestic Ice Kingdom.

Snow fell onto those lands, and no one dared to mention the former empire's name out loud. A few royalties were also absorbed, and they remained under Ice Blade's strict eyes.

Bartlo was one of them.

Minato told Queen Julia about him and even openly pondered killing the last emperor's descendant and bloodline.

Still, Julia decided to give Bartlo a chance, becoming a minor noble in the harshest land!

Although new lands gave Julia's kingdom a new status, their name remained the same, so they were a kingdom.

Minato appeared in their castle after his short vacation on Earth, "Oh?"

"Welcome, Master," One of the ladies from Ice Blade had been waiting for him.

Minato smiled at her, then told her to guide him to the queen's chamber. The news of his appearance already reached Julia's ears, so she welcomed him with wide arms.

After a few tight hugs, Minato rolled his eyes, "Let me speak with those representatives now."

"You've finally decided to speak with them?" Julia smiled, then took Minato's hand.

He sighed, "What can their goal be? Invite me to their country and give a free pass to the dungeons. I need neither, do I?"

"You don't," Julia chuckled.

Representatives from all countries flooded the Majestic Ice Kingdom and begged for the talk with the Overlord. They did it first, then only paid attention to the ice royalty. Of course, Julia took matters of her kingdom already.

Yet, those representatives just sent off their servants to pass the news and waited for the Overlord to speak with them.

Minato stepped into the room where all of them had gathered.

All eyes landed on him for a short moment. The representatives knelt in utmost respect before the strongest existence in their low world.

"It's an honor to be in your presence, Overlord Minato!" All of them said similar things in tandem.

Minato waved his hand, then canted his head to the side, "All dungeons belong to me. Your countries have no meaning in my eyes. I don't have any plan for you other than dungeons.

My home in this world is the Majestic Ice Kingdom," Minato briefly explained.

While all representatives didn't even get a word to say, Queen Julia happily grasped Minato's arm. She stared into his eyes with unconcealable attention.

He reciprocated the glance, then turned around, leaving those people with their dreams shattered.

On their way back to the queen's chamber, Minato parted his lips, "I will start taking dungeons slowly. After I get rid of them, I will wait for Yuna and Bei... That's the plan for now."

"Can I assist you in one of those dungeons? I would like to try myself," Julia asked.

Her strength naturally surged, but she didn't have time to balance it out with the experience. That was why she requested the dungeon raid together with Minmin.

He chuckled, "Yep, we can have fun in the neighboring empire."
