Christian had still not found a human training in a physical power system, that's why he had explained all of that to his sister and Eva, to let them know what he had discovered.
Because, despite his confidence that there was no danger, if either of them didn't want to go through with these exercises, then there would be no problem.
His sister was still waiting for her technique to be made. And Eva… he intended to research her condition carefully, find the problem she is currently facing, and fix it, so that she would be able to train normally.
So, this training… it wasn't necessary, after all.
"I trust your judgment, so I will naturally go through this training," Eva said without hesitation, not even pausing for a moment.
And while Annabelle, who was still processing all this information, felt a bit irritated that Eva had spoken before her, she still calmed herself and asked, "Would going through this training affect my ability to train in another power system later?"
"…Theoretically, no," Christian replied.
He sounded uncertain, but in truth, he was 99.99% sure there wouldn't be any problem later on.
And even if, by some one in a million chance, a problem did arise, he actually had the confidence to solve it.
Still, he decided there was no need to explain that, and be overconfident.
Annabelle, understood that if her brother had even felt the slightest possibility that this method could be dangerous, then he wouldn't do it at all. So, naturally, she didn't ask about safety… she trusted that already.
What she asked about was compatibility, because for her, training in the space attribute was too important to risk anything that might interfere with it.
And yet, as she recalled everything her brother had said, and considered his reply, she too felt that there shouldn't be a problem.
After all, those people trained in essence techniques were still able to raise their strength… even if it was at the cost of cell instability.
They were, at least in theory, able to train in two power systems.
So, with her brother's method being more refined and more exquisite, she doubted that any problem would arise.
And so she said, "I too will trust your judgment."
Annabelle wanted strength, even if there was no place to use it right now, she still wanted it.
With that settled, Christian smiled and said, "Alright then, I'll demonstrate the moves you need to imitate."
And while feeling happy that they had that much confidence in him, Christian began moving his body.
He performed the movements with ease, as if they were something anyone could do. But he naturally knew, that wasn't the case.
He doubted his sister and Eva would be able to get through all of them today.
These were movements based on his Flawless Body skill, after all.
A skill he had come to understand more deeply over the past week.
A skill that was related to flaw… to the concept of talent in essence, and to many more things.
A skill that pursued the perfect body he wanted… and with it, the potential that such pursuit would bring.
A skill that, had he trained in it… or researched is more accurately, in real life, would have left his body beyond ruined, but because of the Idle Practicing of his system, he had only received the positive effects of it.
Since the moment he gained the Flawless Body skill, since he read its name and began receiving the idle accumulation of it, Christian had come to understand what it truly represented.
He understood that this skill wasn't simply related to physical strength.
And he didn't mind that.
In fact, he was happy. Happy that it meant he would later have a higher potential.
But still… when time passes with no visible results, one is bound to get discouraged.
Especially when he hadn't yet touched much of this "essence potential," and had only raised his constitution a little from it… as a mere side effect.
But this week, through personal research, through testing, observing, understanding… he had come to realize just how much he could have raised his physical strength, had he focused on it from the start.
He came to understand just how precious this skill really was.
It was a little contradicting.
The lack of results had led him to understand its value.
But who could blame him?
There were still no tangible results… not the results he wanted at least. Just a slight raise in constitution… a small raise.
Now, though, he simply understood that this skill was unlike the new physical, strength based power system he had discovered.
It was something… more.
And that was naturally, a happy thing!
Putting all of that aside, Christian, who had finally finished his demonstration without breaking a sweat or showing any sign of tiredness, looked at Eva and his sister and said, "Okay, now it's your turn."
He stared at them as they remained still, and chuckled before saying, "Don't worry, just do what you can. There's no need for you to do the complete set."
With that, they finally snapped back and, without saying anything, just started moving their erotic, tempting bodies.
Christian tried not to be distracted by how the same moves he had designed purely for practicality were now turning into something closer to seductive poses. Instead, he focused on observing them carefully, so he could point out the mistakes they were bound to make.
And naturally, there were plenty.
So, he walked toward them, and while placing a hand on Eva's slim waist and feeling her bare skin, he said, "You need to lower your hips more at this point."
His hand lingered on her soft skin as he corrected her, but in the end, he still withdrew it.
They were seriously going through these difficult moves, after all. And he didn't want to hinder their training.
He continued correcting them for nearly half an hour, until finally, Eva, unable to endure any longer, collapsed onto the ground and lay on her back, saying, "I'm out."
