There was no fixed way to increase the Mastery over one's Physique, one just has to keep trying and trying and hope to achieve a Break Through.

Nux, however, was different.

For him, all of this needed only one click.

[Physique: Devouring Mist Demon Physique – Acquired (+)]

He clicked on the (+) sign that was on his system and,

'Huh?'

Suddenly, Nux's world turned black.

No, that's not right, rather than his world turning black, it was more like he was transported into a Black Space.

'What is happening?'

Nux frowned.

He started looking around, however, there was not even an ounce of light in this place. He cannot see or hear anything.

He tried touching his face with his arms and it worked.

He could feel his body.

However, he could not feel his clothes.

It was as if he was standing naked right now.

'Edda, Skyla, Lane, Thyra.'

He tried calling his women.

Or his women that were in Alger's mansion right now.

'Yes?'

'Nux?'

'What happened?'

'Hm?'

The 4 women answered.

'The Harem Seal is working…'

Nux thought inwardly and then, he called everyone.

'You guys, come into my room.'

'Alright'

The girls didn't joke around either, from his tone, they could tell that he was serious.

The girls quickly rushed into his room and soon, Edda's eyes widened in surprise.

"Nux!"

She wanted to rush toward him; however, Thyra grabbed her hand and stopped her.

"What are you doing!?"

"Shut up, you will die if you touch it," Thyra muttered with a calm look on her face.

'What do you guys see?' Nux questioned.

'Were on lying on the bed?'

'I was.' Nux nodded.

'Your body is covered with some sort of Black Mist, nothing is visible, the fact that it is your body is also just a guess.' Thyra answered.

'Black Mist?'

Nux frowned.

'Yes, not only that, but I sense a menacing energy from that Mist, it is as if it will devour me if I go too close to it.' Thyra muttered.

'Alright.' Nux nodded.

He doesn't have to be a genius to realize what this Black Mist was,

It was Black and Thyra labelled it as lethal.

Nux was sure that it was Devouring Mist.

'Why are you two so calm!?'

Suddenly, Edda questioned.

'Oh my perverted Edda, are you worried about me?' Nux questioned.

'Of course I am! What happened to you!? What is this Black Mist covering your body.'

'Alright now calm down. Nothing happened, I will be back to normal after some time. I just acquired the Devouring Mist Demon physique I was talking about. Don't worry.'

Nux answered in a calm tone.

Edda and the others calmed down a little and then, Nux continued,

'Now answer some of my questions.'

Nux then raised his hand inside the black space and questioned,

'Did my hand move?'

'There is no movement in your body.' Edda answered.

Nux then jumped and questioned again,

'Now?'

'No, there is no movement,' Lane answered.

Nux then tried controlling his Mana, however, he quickly realized that he can't access Mana in this world.

He tried using [Sense], however, other than the pitch darkness, there was nothing else he could see.

'Nux… you will be alright, right?'

Suddenly, Skyla questioned in worry.

'Oh C'mon, don't worry, it will be fine, I know what is happening.'

Nux muttered.

'Alright, you all should leave the room now, things might get dangerous.'

Nux muttered and his women left the room obediently.

Nux then broke the Telephatic Link and sighed,

'Now how the fuck do I get out…'

Yes, he did not know how to get out of this situation either.

He was just trying to calm them down.

He started looking around, however, being in this dark place, there was nothing to look for.

Then, Nux closed his eyes and started recalling what was written in the Mantra of the Devouring Mist Demon, however, nothing came into his mind.

There was nothing that is moderately close to his situation mentioned in the Book.

Nux scratched his head in confusion.

Now, even he started panicking.

'What the hell? Shouldn't I just level up? Why the heck is something like this happening? C'mon, if there is some sort of task that I have to do, just give me that task. What's with this pitch black welcome?'

He started talking to himself, trying to keep his sanity and hoping to receive some kind of hint.

"…"

However, only silence greeted him.

No answers, no hints, nothing.

Now, Nux started panicking even more.

'System! System! Can you tell me what is happening? You can help me right?'

He called for his last resort.

"…"

However, just like always, the System did not respond.

'Maybe conscious systems are better than unconscious ones, they might be annoying, but at least they answer the questions…'

Nux started thinking about random things while he panicked.

This continued for 5 minutes and Nux, who was about to have a heart attack due to panic felt something change.

The pitch black space suddenly cracked and then, it broke down like a piece of mirror.

Nux then tried opening his eyes and a big sigh escaped his body once he saw a familiar ceiling on the top.

He stood up and looked around and soon, his heart calmed down.

He had returned.

Then, he glanced at his body and although there were no apparent changes, he could feel something was different.

Something in his body had changed.

He raised his hand and Devouring Mist moved out of his palm,

Nux noticed that this Devouring Mist was darker than Amaya's not only that, he could feel that it was more lethal and stronger.

Then, as if he knew about it since he was a child, he started discovering more and more things he could do with this Devouring Mist.

A small smile appeared on Nux's face.

'Two, Three.'

Suddenly, he called.

'Yes Master?' the two assassins answered at the same time.

'Come spar with me.

I need to test something out.'
