System vs Rebirth

"Basically, the parabolic movement is just you extending the movement of your body." Elsa raised a finger, giving Noel the shortest explanation possible.

"Extending the movement of my body?" Noel tilted his head in confusion.

"Yes." Elsa took out a small coin from her pocket and threw it into the air. "Look at the coin. After we throw the coin, it will create a curve to go up to the highest point before going down, right?"

"Indeed."

"This is what you call parabolic movement. You create a curve to the limit before it goes another way. If you take a look closely, this kind of movement is like you extending your body and attaching that coin to a thread, right?"

"Well, that's true." Noel nodded in agreement while raising one of his fingers, imagining the thread that tied a coin. If he swung the coin, it would create the same movement. "But doesn't that mean we can create a movement from the side or probably from the bottom?"

"Yes. You can. You can imagine yourself extending a part of your body to create that movement. That's why I said it's just an extension of your movement."

"I see. I can understand that."

"Since you've understood the principle of the motion, I'll start with the theory on how to curve the Spiritual Energy." She nodded with a serious expression before beginning her explanation.

Elsa's words were a bit crude and hard to understand. Seeing Raincart was sitting on the side just observing them meant Raincart used this chance to help Elsa in this area. If they truly didn't reach anywhere, he would surely help with the lesson.

Whether it was fortunate or unfortunate, Noel managed to keep up with her explanation.

"I see. To put it simply, the curving Spiritual Energy is based on our movement. No, it's more like this motion is the one helping us to learn it. If we have mastered it, there's no need for such a movement."

Noel furrowed his eyebrows while waving his hand. When it was rotating clockwise, Noel made a motion as if tossing a ball from the bottom. The ball would create a parabolic movement until it reached the ground.

Meanwhile, when he tried the counter-clockwise direction, he threw the ball to the ground directly.

"Hmm… This is weird." Noel narrowed his eyes.

"No, no, no. You have to use your Spiritual Energy to keep going upward as if the Spiritual Energy is spinning." Elsa scratched the back of her head.

Raincart chuckled and finally entered the lesson. "Alright. Let me give you an explanation. If you gather the Spiritual Energy in your hand and throw it forward, it won't go down like what happens if we throw the coin, right?"

"Yes." Noel nodded.

"Then…" Raincart formed a ball with Spiritual Energy and pointed at the top part of the ball. "What if I make the top part continuously flow to the bottom, creating a kind of spin?"

"If that's the case, won't it give you an extra force to go down? After all, if the Spiritual Energy spins, it will generate a force downward."

"Exactly. What if I add the spin from the bottom?"

"Ah! It'll generate an upward force, causing the ball to go up."

"That's the basis of curving Spiritual Energy."

"I see." Noel nodded in understanding. Elsa took more than twenty minutes, but Noel still couldn't understand it. Meanwhile, Raincart only needed a few sentences, and Noel completely understood the concept.

"I apologize." Elsa scratched the back of her head, feeling embarrassed about her own ability.

Raincart nodded with a smile. "Then, how do you create that spin?"

"Giving it extra energy?" Noel asked.

"Yes. That extra energy will cause the spin to happen, and the Spiritual Energy will continue flowing that way. If you put too much energy, the spin will be too fast and you'll miss your target. On the other hand, if you put too little energy, the spin will be too weak to the point it won't even curve."

"I see. It's trial and error."

"Exactly. But once you get the hang of it, you'll know how much you need for all techniques you have." Raincart nodded, confirming Noel's theory.

Noel thought for a moment. "I can try it, but I don't know if my control is enough or not."

"Do try it. Elsa will be next to you." Raincart finally walked to the side, returning to his original position and leaving the rest to Elsa.

The training continued as Noel had a hard time adjusting to Spiritual Energy. Even a small error could actually cause a high deviation, making it extremely hard to adjust.

But considering this was just flowing one motion, which was the parabolic curve, there was only one spin that he had to add. It was the reason why the Parabolic Movement was one of the easiest abilities to learn.

Still, even if Noel couldn't learn it when he was in this family, he could continue practicing this ability after he returned.

For the time being, he completely focused on the matter at hand until his stay was over.

After a few days, Noel was ready to leave the Ezenholm Family. The visit was more useful than he thought and he had gotten a lot of information from Raincart's investigation.

Since the situation around the border wasn't stable enough, Elsa and Ilzen escorted Noel until he reached the Muivell Kingdom. Raincart actually gifted him a horse that he could use whenever he wanted without the need to borrow it from the Demon Banner Army. It was quite useful, so he took it.

"This is the furthest we can escort you, Young Master." Ilzen politely bowed.

"Thank you." Noel nodded with a smile. He hesitated for a moment but still took out his notebook, handing it to Elsa. "Can you tell my grandfather to keep this? I've been hesitating this whole time, but I think this notebook will be better in his hands."

"This is…" Elsa furrowed her eyebrows, reading the title of the book. "Introductory Rune Book."

Because of Anna, Noel ended up naming it this way since he didn't want others to think he plagiarized someone's book, not knowing he was the one actually writing that book in his previous life.

"Well, just hand it to Grandfather." Noel smiled and waved his hand. "Now that everything is finished, it's time for me to leave. Take care."

"Yes, Young Master." Elsa and Ilzen politely bowed their heads until Noel was far away.
