Alvin wanted nothing more than to give the wisp a beating, that is. 'Now everyone is paying attention to me, idiot! What if they found out about our secret?'

Linfel's words carried a heavy truth, his expression reflecting the weight of his past. 'Alvin, a life spent in hiding is a life half-lived. Trust me. As a wisp, I've had to hide a lot, even with Horan's backing. This is not a path you'd like to choose.'

Alvin was a little touched by how grave Linfel looked and ended up sighing in the end. 'Fine... At least you are good at coming up with stories. Just keep doing it fro-'

"Oh! Look at the time! Anyway, Alvin, give your own accounts of what happened to your classmates. Everyone, if you have anything to ask, this is the best time. I have my own Familiar Class to take, so I bid you all farewell!" Linfel quickly floated through the window, disappearing in the distance.

The rest of the class was only waiting for that opportunity. They all gathered around Alvin, much to his despair. 'I'm truly starting to regret bringing him to the academy.'

Linfel was also promoted to a Rank C Familiar, so he didn't need to go too far. There was one thing Linfel still didn't know how to do. That was how to increase his Level. So far, he still hasn't managed to integrate Magic Energy into his core. That was the Class he applied for when he joined the Academy was related to this topic.

Familiars would usually stay with their Masters, so very few of them took classes on their own, especially since they were all born with most of the necessary knowledge. When Linfel arrived at the building where he was supposed to take the class, it was almost empty except for a Familiar working as an attendant there.

"Hello! I scheduled a class for Magic Energy Integration and the basics last week. This is the right place, right?" Linfel quickly asked in high spirits.

The familiar looked at him and nodded. "That's the one indeed. Let me see here. Put your Magic Energy in the receptor so I can check your Magic Signature."

Linfel quickly did as such, and soon, a lot of information regarding him appeared for the Familiar. "Ah, yes. Your class is in Room 7B, down that corridor. There is another Familiar who will take the Class with you, so try to get along."

The genuine version of this novel can be found on another site. Support the author by reading it there.

"Naturally!" Linfel left straight away, going down the corridor and passing by the rooms.

The 7B one appeared not long after, and Linfel entered it. Inside, there was already another Familiar, also with Yellow Color, showing it was a Level One. "Hey, nice to meet you! I'm Linfel."

The other Familiar was surprised that someone else appeared. Nonetheless, it also saluted back. "H-Hi... I'm Siana, born just a few days ago."

"Oh!" Linfel hadn't met a completely new Familiar yet. "Are you doing well? I wasn't expecting any Familiars in his place since this topic is already added to your knowledge during a Familiar's creation. Are you like me, a Familiar without knowledge?"

Siana nodded slightly. "My Master created me like this as a test. So I will have to learn everything from scratch."

"Just like mine, then," Linfel added. Of course, he was lying. It's just that that was the story he and Alvin have been using. "Sheer up! This is a good thing. You will avoid the Knowledge Curse. Although you will lag behind during the first years of your life, you will have a better prospect later. Of course, only you put in the effort, that is."

Suddenly, another door in the room opened, and another Familiar appeared. The Magic Energy that gave form to his ethereal humanoid form was brown, the mark of a Level Three Familiar. "Hum? There are two today? I was already surprised to get one at all."

Still, the Familiar continued. "Anyway, you can call me Lokasto. This is an introduction to Magic Energy integration. I will first explain how it works, and then we will delve into the several methods used by the Familiars out there. Pay attention since this is deeply related to how fast you can Level Up in the future."

During the next few hours, Lokasto went through the basics of Magic Energy integration. Turns out that the Integration the Familiars did was a lot more different from what Maguses do than Linfel expected. Once a Familiar Absorbs Magic Energy, it is stored in its core. However, if you wanted to Integrate the Magic Energy into the Core itself, you couldn't store it.

Instead, you had to accumulate the Magic Energy in the channels that led to the storage part of the Core. From there, the Magic Energy would slowly sip into the Core itself, increasing its level little by little. Naturally, the higher the quality of Magic Energy, the faster that integration happens. It's just that the limit was the same as the Maguses.

One couldn't integrate Magic Energy that was more than one level above the Familiar itself. In Linfelia's Case, for example, the most she could use was Red Magic Energy. Brown Magic Energy, which you could call Level Three Magic Energy, would be useless to her.

Lokasto presented Linfel and Siana with a few different methods that used basically the same principle. Ultimately, one would still need to fill their channels with Magic Energy.

That... caused a big problem for Linfel. He doesn't have any channels to speak of! The Magic Energy he absorbs goes through his core as if it were falling into a lake and falling to the bottom where the pool is. It literally passes through his core without having to go through any channels whatsoever. It was also through this process that he cleaned the Magic Energy for his own use. His Core was the filter.

However, that class wasn't completely useless to Linfel. That's because he had an idea after hearing about the overall process. 'Hum... I can't fill my channels since I don't have channels to start with. Yet, I'm my core, and my core is me. What if I fill my soul instead? My soul is spread through the core; they are one and the same.'

Such an idea would have been considered ridiculous back in Linfel's time. After all, primordial energy was too chaotic and dangerous. If you didn't die straight away, you would definitely damage your soul at the very least. 'But...' Linfel continued that train of thought, 'Magic Energy is extremely gentle and easy to use. This is the only way I can think of to integrate Magic Energy into my Core. I can only give it a try later.'
