Apex Predator.

"[Cadets] can also post [Missions] in the [Adventurers Guild] if they have enough [Ri]s, gold, silver, of bronze that could be earned even within the [Worlds Academy] by participating in events, competitions, battling, and many more, that you'll learn about as you continue live in the Academy.

[Worlds Academy] schools people aging 15 – 35, older can join the [Adventurers Guild] to fend themselves off, of course, they are taught the basic, hunting methods, rules and required necessaries before they can begin adventuring officially.

You have the advantage in the academy while in the guild, your life is under a constant threat, that is if you want to make a living out of adventuring. Academy teaches you things slowly and your growth is guaranteed, you have a choice to choose, but anybody and everybody would recommend and advice you to pick the academy.

And next is the [Second World Of Aerith], which is our home planet, Earth, but it is better off not said to be so anymore, as I'm pretty sure that it would merely be another world that houses monsters of all kinds. Humans or any other races for that matter only inhabitant the [First World Of Aerith] and the [Third World Of Aerith]; it would have been only the third world, but due to those of the "other world" "spawning" here, the first world also houses a small number of inhabitants.

I have yet to mention, but I'll let you know that the monsters that [Manifest] in those worlds that house people are from these planets; [Second World Of Aerith], [Forth.....], and [Fifth World Of Aerith] namely.

These three planets are planets that house monsters that number nearly limitless, and all the [Labyrinths], [Ruins], and [Gates] are phenomenon that occur due to the connection between all five planets. And it is proven that these phenomenon affects the populated worlds when ever [Mana Overflow] happens. An affect that's nearly self explanatory.

But the reason it happens is due to the world birthing stronger monsters, or when the birthed monsters grow over the limit of monsters that world can house.

To reach the third world, you have to, at the very least, reach level 5 which is bare minimum requirement, and after reaching level 5, to [Graduate], you have to go through the [Altar] that determines whether you are qualified enough to reach the next world, which is the [Third World Of Aerith], or not." Velor explained, as his words reminded Ivan of the [Tower Of Trails] from [Hell] as his brows narrowed at the similarities it held, but his thoughts remained unvoiced while Velor continued.

"There are merely 3 human Kingdoms, a [Magic Tower], a [Assassin Dome], a [Holy Empire], and a human Empire; these mentioned lands host humans, mainly. And there are Kingdoms of the other races too, but not many are open for the rest of the world, and with their levels of magic, we, the humans, won't know even if they existed among us.

There are 12 main families that house the so-called powerhouses, they are the nobles from the "Empire," but of course, those aren't all, as the kingdoms hold 7 of their own, and these powerhouses in the kingdoms are called the [Seven Deadly Sins], while the nobles from the Empire are called the [Zodiacs]; I can't explain any more deeper into why and what about these Nobles and Guilds are, as those of the [Frist World Of Aerith] aren't considered as [Citizen] of the [Third World Of Aerith].

The power that is segregated into [Aura] and [Magic Power] is known as [Mana], or the [Origin]. And the [Origin] is the [Essence] that has been said to have existed since the beginning of the Universe. There are many theories that claim that the subsequent [Origin] that has nurtured with [Aerith] has become denser over time, which is the reason behind the suffocating atmosphere in the worlds of Aerith.

Some even claim that the [Origin] is the energy of the stars that remained even after Aerith had been created, and as the energy of the stars gathered in Aerith as [Time] passed, the more suffocating Aerith's atmosphere became. Of course, this changes and claims are from the people of our world, since none of the inhabitants really felt anything as these changes happened over time, they never cared much for that matters.

Core's rank up and level up.....

I don't know how you know of these things so early, but I'll explain.

Core's rank up increases the amount of [Magic Power] or [Aura] one can store, it becomes easier to wield, handle, and it also becomes denser with each rank up, with a bonus of subtle [Physique Enhancement]. But level up is far more efficient then a core's natural rank up. Levelling up once increases the three most used stat points by one at random; and if you are using any variants of [Mana] most of the time, and you level up at your bottleneck then you'll experience a clear and efficient break through, without having to stagnant or experience the torturous pain of having your "impurities" removed, since with the bottleneck level up, as the powers merely overlie the impurities in one's body; storing them and possibly ending one's life as a power wielder.

And if you want influence or even have any "weight" behind your words, then you'll need to be at least at [Rank-A], where you are able to wield the power similar to that of a [Baron].

Additional info;

There are [Returnee]s, who are called [Gods]. Because the [Title] [Returnee] that they hold, gives them a boost in their growth with the [System]'s permanent [Protection], and there was even a revelation recently that stated and announced a birth of another [God] that is said to be stronger than all the [13 Gods] that already exist.

You can think of it as my reason for being here in the first place. Ah, and one more good news for you, the ratio between men and women is 1:7, respectively." Velor, who had continued to speak for three to four minutes without even taking a breath, finally ceased to speak with a playful smile thanks to the gentle and friendly aura that surrounded him, as he suddenly felt a something stinging near his neck.

He looked down and jerked back upon noticing a tense, slender palm gazing his neck. He had unknowingly gotten comfortable as he continued to speak and give out information, if he hadn't snapped out of that state thanks to the prickling feeling in his neck, he might have involuntarily revealed much more information than he was asked for.

He then glanced around in puzzlement and fear, only to notice that the brightness that dyed his world had disappeared as those around them were staring at them with confused expressions marring their faces.

"It appears that you are informed far more than expected. In respect of your knowledge and patience, I shall let you live, but I must warn you, the moment anybody other Sir Velor learn of matters concerning here, you shall be suspected first, and my suspicion lead to executions, most of the time." Said the green-eyed man, who hadn't even turned to face Velor even after he had intruded their conversation.

GULP-!

Velor swallowed heavily as he began to tremble again, while the grey-haired woman's nails dug deeper into his throat due to the moment caused by his gulp. Still, he managed but limited himself to a nod.

"Nu." Upon the green-eyed man's call, the palm on his neck retracted back, but the alluring woman's figure leaned towards him the next instance, freezing him in spot as his toes turned cold.

"You ought to be grateful for His Majesty's merciful nature, else you wouldn't have known what beheaded you, you lustful mortal pig." The woman named Nu whispered in his ear, it was at that instance that he felt as he was nothing but a helpless mere livestock trembling in front of an apex predator.
