God's Slave: Reincarnated Into an Academy of Heavenly Descendants

"The last category is the Titan Realm, the home of our enemies. It is contained in the lowest planes of existence, which are none other than the 1st, 2nd, and 3rd planes."

"It is a brutish and harsh world that almost none but the Titans themselves can survive, contributing to their incredibly powerful physical bodies."

"Their bodies have evolved to adapt to the harsh environment, growing bigger, stronger, and tougher..."

"So evolution is also a thing in this world too, huh?" Nolan mused to himself. His attention was now piqued, and a single question was ringing in his head.

Just who are the Titans, and why do the Celestial Heirs seem to hate them so much, tagging them as 'our greatest enemy?'

But another question also appeared in Nolan's mind.

If the nine planes of existence were divided into three, containing the Celestial Heirs, mortals, and Titans, then which realm did the beasts and the so-called Nightmare creatures belong to?

Do they live with the Celestial Heirs, the Titans, or the mortals?

It was a subject Sir Alberto didn't touch on, unfortunately, but it was only a matter of time before Nolan himself found out everything.

"With the basic understanding of the world revealed, we will focus on the most important realm, which is the Celestial Realm."

"As I said, the Celestial Realm occupies the 7th, 8th, and 9th heavens."

The Academy is located in the 8th realm, and it occupies the entirety of that realm!" Sir Alberto explained, causing Nolan's eyes to flash in shock.

The Academy was so big that it took up an entire realm for itself!?

"Then there is the 9th realm, whose existence and activities are beyond your understanding."

"You will only learn about what occupies the 9th realm after you have reached a sufficient level of cultivation..." Sir Alberto said, and Nolan's eyes dulled.

He turned to look at the class and found they had similarly interested but disappointed expressions.

It was clear to all that they already knew they couldn't obtain information about the highest plane.

"Then there is the 7th realm, which is the homeworld of us Celestial Heirs."

"Our main focus throughout this entire session will be on making sure you understand as much as needed about the 7th realm, our homeworld."

"As you may know, it is divided into a total of ten cities, each representing a different Mythological descent..."

Calmly, Sir Alberto properly explained the structure of the Celestial Homeworld under Nolan's rapt attention.

Repeatedly, Nolan's mind was getting blown away by the information.

RIIIIIIIIIIIIIIIIIIING!

After a total of three hours of non-stop explanation, with Nolan absorbing as much as he could, the bell finally rang, and Sir Alberto waved them all goodbye before leaving.

"Huuuuuu," a loud exhale left Nolan's lips as he held his thumping head in his hands.

"The world... The world is too vast. So vast I don't think I will ever find the end of it..." Nolan mused in a mixture of anticipation and sadness.

The world was simply too big; he couldn't imagine exploring every inch of it.

The 7th realm, which was the homeworld of the Celestial Heirs, was already enough to blow him away.

What of the three remaining worlds of the mortals

or the three harsh worlds of the Titans?

Or the hidden 9th realm, which couldn't be revealed to the students until they reached a particular strength or status?

Just what is the Academy's importance, so much so that it is allowed to occupy an entire plane of existence on its own!?

Just what is this world hiding, and why was he even reincarnated here in the first place...

'One day. One day, when I have freedom at my fingertips, strong enough to go anywhere or do anything, I will explore every inch of this world and its secrets...' Nolan swore to himself in conviction.

But he was snapped out of it when he felt a tap on his shoulder, waking him up from his dreams.

Looking forward, he could see who had tapped him.

It was none other than the fat guy and his goons, who were laughing as they moved towards the exit.

One of them stopped, pointing outside the door before turning to swipe his hands over his neck at Nolan, and they all burst into laughter and left.

It was a sign that Nolan knew very well, and it meant that if he dared to leave the classroom, he would be dead.

But looking around him, he could see the various Celestial Heirs were all packing their bags and heading out of the class, revealing that the class had ended for the day.

"Wow, how come the class is so short?" Nolan wondered to himself with furrowed eyebrows.

[The class was not short at all. The first session took a total of 4 hours, then you all had an hour break, and the second class lasted a total of 3 hours!]

[That is a total of 8 hours a day! How is that short?] The system asked as Nolan scratched his head.

He never even had an idea time had gone by so fast.

It must have been because of what was being taught. It had attracted his attention so much that he had no idea time was moving by rapidly.

'It's also time I get going. I need to get new books to write the assignments, and perhaps, I can take a small walk to the library and properly understand more about this world, so I don't look like a dummy in the next class.

And perhaps, I could start preparing for my next quest.

"I have so much to do..." Nolan mused as he also rose up and walked out of the class.

He had no bag or whatever on him, and so therefore he simply stepped out of the class just like how he had come, with everything taught placed in his brain.

But little did he know of just how much trouble was waiting for him....
