Yuki simply asked all of them to which they all complied as they all then showed her their Soul Realm and its current state. When Yuki saw all of their Soul Realm she was pleased that all of them were at least at the Rank of Ascendant with two individuals even making it close to Crystalized which made her take a second look at them as she didn't expect it to be.
Of course, looking at her perspective, Yuki was almost sure that if someone were close to having a Crystalized Soul Realm, it would be Solar and Najin, but it seems that she was wrong, as the two people who are close to reaching Crystalized Soul Realm are Lisa and Nayeon. But what is shocking the most for Yuki is that the other two who were just behind Mio actually had the worst Soul Realms out of everyone in the group.
"Well… that is certainly something I didn't expect to see. Solar and Najin equally have the lowest Soul Realm in terms of power and quality out of all of you. But don't worry we can change that, but expect now that because of that you two will struggle harder than the rest of them. But don't let that drag you down, instead make it your motivation." Yuki told all of them, as she looked at both Solar and Najin, to make sure that her message got through to them and that they didn't get depressed because she stated the fact.
But after seeing that the two simply shook their heads and bowed their head respectfully towards her, she already knew that Solar and Najin didn't get offended by what she said, and that made her glad as she simply continued with the lesson.
"Now. Follow my lead. Materialize in the air a single point of your Mana, if it is done correctly it should look like this as this is how Pure Mana looks like. Now I want all of you to do the same, don't worry if it explodes because it is just normal as this is the first step, controlling and purely manifesting your Mana." Yuki said as she simply snapped her fingers and a blob of white light appeared right before them Yuki simply controlled it as she showed them to everyone so that they could have a better look at it, and have more confidence in recreating it.
All of them simply nodded their heads as they then tried their hardest to manifest their Mana in the air just like how Yuki showed them, but just as Chisato and Yuki expected, even though they had successfully manifested their Mana outside, it exploded because they couldn't control it properly.
"Keep calm and try again, control it better, stay focused. You'll know you passed when you can control your Mana if it flies in the air at your own will, but of course one of the best ways to know is when it doesn't shake violently, or of course explode in your face." Yuki said as she walked around them while they struggled.
Some even already sat on the ground to have a better focus on it until everyone finally sat and Yuki and Chisato just walked around all of them while giving tips and guides on how they can control it properly, though all of it was just some words of encouragement as there is no real trick in controlling them, it is just pure Skill.
But after just half an hour of trying and failing, someone was finally able to complete it, and just as Yuki and Chisato expected, it was Nayeon who had the highest purity of Soul Realm as it was the biggest factor in manifesting and controlling Mana. But it didn't take long before everyone caught up to Nayeon as just a few minutes later some would also pass and make the manifested Mana without exploding until all of them could finally do it easily.
"Good. Even though it took all of you longer than what I initiated, it's fine. This is a learning process after all. Now that you have Manifested that Mana, take it back. Simply absorb it, now this is crucial… because if you fail, you'll feel pain in your Soul Realm, but don't worry, it won't harm you, you're just going to feel immense pain." Yuki said to all of them which made them swallow their saliva nervously.
But that wasn't enough for fear to grip their hearts and minds as all of them went on and tried just as Yuki instructed them, and just moments later, the whole place was covered with the sounds of grunts in pain. Even though Chisato felt pity for all of them, she knew that it was necessary because it was absolutely what they needed if they actually had the intention of defeating the Gate of Abomination.
"Master… would it be fine if I recorded this? But don't worry though! I won't show your face, I won't show your face to the camera, just your voice teaching them how to manifest and have better control over your Mana." Mio asked after she woke up and realized what was happening minutes later after observing, so she took this chance could record it and show it to the world.
"You don't have to. I'll just give everyone a basic tutorial through the System, if they learn it or not, that is up to them. I'm not here to babysit anyone, you guys are just special because they're your friends." Yuki said as she immediately shut down that idea as she hated it completely.
With just one rejection, Mio already understood and didn't try to persuade her Master any longer as she could feel her irritation through that rejection as it meant that she didn't want to be recorded even if it was only her voice that was going to be showing.
"You should rather think of how you can teach better in your Class. From what I heard from Somi and what I could see, you are teaching your students Magic Theories. It's good that you have started in the most basic parts as they need a good foundation, but you quickly need to advance it. I took a sneak peek at what is the plan for your School and I saw that they are planning to have a trip inside one a Gate to make them learn. I see this as a chance to get ahead, I'll make a special gate just for you if you want me to." Yuki suddenly offered as she looked at Mio while letting Chisato overseer the rest as for now she wants to talk with Mio about her being a Teacher and passing on the knowledge that she got from her.
"It doesn't mean that just because you are their Magic Theory Teacher it should be the only thing that you're going to teach them. Make them learn everything, especially the one class that you are managing. I saw two potential there and can be your own disciple because of their talents, they just need the right nurturing." Yuki said while she placed her hand on top of Mio's shoulder as she gave her some news about her Class.
