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

Due to the elven might, Minato's conquest was too easy.

He didn't expect it, but he remained gleeful while looking at all ice creatures thrashing within the veins coming from Ingrid.

The elven queen briefly glanced at all those creatures. She gave them a taunting smirk, then bid farewell as all of them died immediately after Minato sucked hatred out of them.

The monsters didn't even let out a cry as once the hatred slipped away from their bodies, their all movement stopped, including those snarling mouths.

Ingrid's expression suddenly changed, however.

Her sharp wind notified her of an incoming army of the Frost Dwarves.

Those were Dark Frost Dwarves.

They all moved in an order... Considering how much hatred bloomed within those eyes, Ingrid inferred that it was due to them getting out at once.

Otherwise, their movement would've been much different.

"Master. What are your plans toward the Frost Dwarves?" Ingrid asked.

It might seem like every dungeon race would want to get out of the dungeon. It was quite the wrong approach as some races would gladly cooperate with the hatred... Trolls, orcs, goblins, or even higher races such as succubuses.

Those races would surely like the hatred's approach.

Another thing was that Minato didn't have to accept the whole race.

It could be his preference, or simply the dungeon race's characteristics wouldn't suit him up.

Should it happen, the overlord would have three choices at most.

Use the race as slaves or disposable force... Sell them on the market or simply exchange with other Overlords.

As the universe was vast, someone would find a way to use other people.

Minato didn't think much for now.

He replied, "I will get rid of their hatred, then we will see. I think all of us liked the ice volcano, so they should lend us a hand here. And, I feel like a different climate would be good in our world."

"I understand," Ingrid nodded, her powers extending toward the Frost Dwarves.

Frost Dwarves were known for their ice craft.

Their ice sculptures momentarily gained souls and became genuine beasts for their masters. That was for the offensive.

For the defensive, the frost dwarves excelled in traps and ice buildings, which could become mazes or big puzzles!

Appearance-wise, the Frost Dwarves were relatively small.

The tallest Frost Dwarf was around 150cm, while the smallest would be around 120cm... Their usual height was in between, which was about 135-140cm! Their bodies were also unique, with blue skin and crystal eyes.

Their hairs were blue, and their shade decided the hierarchy in their tribe. The patriarch was a man with the brightest blue hair!

All of them were dark, however.

It was due to the hatred brimming within their eyes. That unique energy oozed out of their bodies as well.

Hatred streaks fueled their bodies further!

Minato's hand clenched unconsciously, "I will help you deal with them."

He rushed forward without waiting for Ingrid's reply. His body urged him to get rid of that hatred, and Minato didn't find any reason to refuse that feeling.

The Elven Forest didn't interrupt his charge.

All bushes disappeared from Minato's path, and veins returned to the trees like snakes that suddenly heard their queen's call. Even those trees bent away so that their master would casually reach the first frost dwarf.

At last, Minato faced that short man!

"KILL!" The Frost Dwarf screamed in a hatred akin to a genuine one.

Minato didn't react, remaining stoic and ready to fend off every ability. His eyes widened after the frost dwarf threw a tiny spider at him.

That spider was made out of ice... It surged in size near Minato! It became two times bigger than him, and its body alone would be able to trap him.

That was not enough, however.

The ice spider spat the ice web. In a flash, it covered Minato from nearly all sides! His back was free for a few seconds!

Minato didn't plan to run away, though.

Even if he couldn't use any magic circles due to his active box, he was also aware that the frost dwarves were far weaker than the elves. Their bloodline stood no chance against the elves, and other frost dwarves lived in medium or even low worlds.

"That alone can not stop me," Minato declared.

His punch barrelled into the ice spider, destroying it far more straightforward than ice monsters from before! He kicked away all the pebbles and grabbed the frost man's face!

Not saying any word, Minato threw that man behind himself.

The Elven Forest grabbed that flying body and not so gently put him near Minato's box... Well, the elven treatment wasn't pleasant, but not wrong either. Should Ingrid do nothing, that body would've dropped quite heavily.

Fortunately, Ingrid read her master's mind well.

After he smiled at her, she was happy, then Minato continued his work.

He released his anger toward the dark energy by beating a few more frost dwarves. They all went on the offensive, so their hands threw and summoned many ice sculptures...

Naturally, all of them shattered beneath Minato's might.

He then spun and returned to his box.

Many Frost Dwarves had long since been saved from the hatred. They kept looking into each other's eyes with confusion and immense happiness within.

After Minato approached them, all of them stood up and bowed to him, "Thank you for saving us, Master."

"I guess you all want to leave this dungeon too," Minato peeked into their crystal eyes.

Even if those eyes were the first unique eyes he ever saw, Minato saw how they shone with happiness. 

He didn't doubt it was happiness.

Their eyes glimmered like crystal lamps.

"That's undoubtedly correct, Master. Once we regenerate our mana, we will assist you in your dungeon conquest. Please, use us as you wish," The oldest Frost Dwarf spoke.

Even though he was just 140cm tall, his facial features told about his longevity and experience. He was undoubtedly an old veteran who had lived in his world and the dungeon for some time already.

Minato didn't mistake any of them as kids.

It was easy to tell as adult frost dwarves didn't possess any shred of innocence on their faces. Their facial features were sculpted by maturity.

Male dwarves also made it easier as they didn't shave their mustaches or beards.

It was even easier on ladies as adult female frost dwarves were all voluptuous without any exception. Either their ass or tits would be abundant in the flesh.

Male frost dwarves also had sculpted bodies with muscles and work throughout many years, so Minato didn't doubt that he faced adults so far.

And it wasn't like Minato had never seen any dwarf on Earth as well...

He remained friendly and serious with them.

Minato gestured to them to sit down, then dropped onto the ice floor as well, "Overlord Enemies. What do you know about them?"

"They are fast... Fast beyond what our eyes can see. Their forte is speed, Master," Frost Dwarf replied seriously.

Because of how deeply he stared into Minato's eyes, he missed Yuna's golden eyes flashing with curiosity and anticipation!

The Fox Wife wanted to see how her husband's body and eyes adapted to speed!
