"I yelled at the captain, the ship's finished charging! Get your ass back to Earth and get the resources loaded up! And everyone else on the island that's just taking a break, you've been working for like an hour, get your asses back to work!' I immediately threw a lightning bolt to drive my point home. Seriously, they work for an entire hour and then they stop. I mean, in my case, I'm simply waiting for my mana to recover before I can summon Earth Elementals. They're highly skilled artisans, craftsmen, here to make very sturdy but luxurious housing so that we can use this island as a base."

"You're quite young and already reached the limit of absorption life force. Whenever you kill a monster, you absorb a small amount of life force from the corpse and use that force to refine your own body. You must have gone through some hellish training in order to have already reached the limit. It usually takes at least a century."

The fairy smiled and said, "You also have a unique magic."

I replied, "That's no big deal. I could have learned it from someone."

She laughed and said, "You can't teach unique magic. Well, I suppose you could teach it if it was incomplete, but it's not really true unique magic if it's incomplete. Once your magic has reached the level of completion, it will transform your body and soul, becoming a unique magical ability that cannot be replicated. The only way for someone else to have the same unique magical ability granted by unique magic is if the unique magic was tied to the bloodline of your race or just your specific bloodline, meaning only your descendants could use it."

The fairy said, "You should form a contract with me." "Why would I do that?" she smirks and says, "The pinnacle of magic is unique."

She continued, "There are many different types of magical systems which have different levels of magic. Since everyone tends to create their own system to categorize it, however, unique magic always remains at the top. This isn't solely because it is powerful, but because it's impossible for anyone else to use it. And it's called unique because it really is one of a kind.

"Once you've reached the limit of absorbing life force, you can no longer refine your body as your body has reached the upper limit. Then, as someone who possesses unique magic, you've already refined your magic to its upper limit. It's impossible to create a spell more powerful than your unique magic. Hell, even weaker unique spells are absurdly powerful. And the longer you use it, the more powerful it gets. That's what makes unique magic so devastating; it has no upper limit to its growth, unlike spells which have a fixed amount of power based on their complexity. For example, no matter how much mana you pour into a fireball, at some point, you'll just be wasting mana and it will stop getting stronger."

"However, I can teach you a method to increase your strength if you're willing to contract with me." "Very well, I agree." The contract was signed, a standard familiar contract. I smiled as I felt the connection between this little fairy and myself.

She said, "Well, I'll explain. Cosmic mana: Planets absorb cosmic mana and refine that mana into their own, atmospheric mana is a combination of the planet's excess mana and all of the excess mana of the living beings on that planet. Living beings generate mana from their souls. In the case of planets with no life, the atmospheric mana is just the planet's leaking mana. However, cosmic mana, you see, is special as it can refine the soul. Not only can you strengthen yourself and increase your mana capacity, but you can also refine your mana into its most ideal form. Everyone's mana is unique, as everyone has a slightly different wavelength of mana, which is how you're able to sense someone's presence based on their aura. It's because their aura is unique."

"The fairy went on to explain the details of how to absorb cosmic mana and use it to refine my soul, stating that you can only absorb cosmic mana to refine your soul if you have a unique magic. It was impressive that I had my own unique magic on top of the unique magic of my race. There's a lot of burden placed on the soul when it's transformed by unique magic, and most souls couldn't handle the burden of two transformations due to unique magic."
