Perpetual Plane!
Oliver's eyes couldn't help but flicker fiercely.
Memories from the novel refreshed in his mind as he realized where this was going…
The Perpetual Plane was an entirely detached space built by the legends of the past, where the strong exorcists from the ancient era poured their resources together and formed this isolated space.
The main purpose for the creation of this plane was to serve as a trial to the young and promising children and give them opportunities to grow stronger.
Just so that only the ones worthy would get the opportunity, the plane was filled with obstacles and deadly beasts captured and released into that isolated space.
It was an important place in ancient times when the war was heavy and promising youth died young due to the terror spread by the demonic forces.
There was no peaceful place for them to grow before the demons invaded and killed them.
So the council of decision-makers at that time resorted to this method. With the help of multiple exorcists, they were able to develop and manage this wide-scaled space.
Over time, this tradition was continued by the clans and the Perpetual Plane just kept getting richer in resources and even bigger but at the same time dangerous too.
The beasts inside mutated to grow even stronger by consuming resources and dense espera, so it was since then that the clan only sent highly trained younglings inside who would emerge out to be more powerful and with ancient treasures.
There was a strict restriction placed to limit the eligibility criteria to being till Rank-3, which was the cap limit.
It was not possible for anyone stronger to enter, forceful means might even distort the coordinates of the Perpetual Plane making it lost in the boundless space.
Of course, no one was willing to take such a risk considering the amount of secret ancient treasures still inside the realm; who knows there might be epic-rank artifacts inside.
Overall, the Perpetual Plane was an excellent opportunity that only a few would ever obtain in their lifetime.
It would not only make them stronger but also provide a scope for them to get life-changing treasures inside.
"Elder, what is Perpetual Plane?" Amber asked, she didn't know about it.
"The Perpetual Plane is a secret space that is opened once every century and is a place filled with unknown ancient treasures and dangers from the past. It is a dangerous place, but for someone strong, it's a place filled with opportunities."
The elder briefed her about it.
Her eyes shone as she heard the words 'treasures' and 'unknown opportunities'.
And it was not just her but the others also had their eyes shining in excitement.
After all, who among them was not ambitious enough, they all wanted to become strong and get many treasures.
However, one of them had a pale expression at the moment.
It was none other than Oliver, his expression was abnormal at the moment and didn't look good.
'No way, the Perpetual Plane… in the novel, it was definitely mentioned that only the protagonist and Nadia were able to enter the Plane, as for the rest of the heirs, there was not even a mention of them.'
Oliver panicked now. In the novel, it was around the time when the Perpetual Plane was opened, however, only Nadia and Evelyn were the ones to actually enter the Plane.
There was not even a mention of the other heirs at all.
Oliver realized he was thinking too much in an instant so he gradually calmed himself; it was not the time to overthink but instead calmly analyze the situation before him with a clear and sharp mind.
'Did this mean that something happened during the joint-training program that made them unable to enter… did they all die? What exactly happened?'
He was not sure but he could tell that there was definitely something that had happened during the joint-training program that rendered everyone except the two unable to enter the Perpetual Plane.
He was calm, at least, this helped him know that something would happen during this joint-training period and it would not pass peacefully.
He had to be on guard as well.
"Elder, what will be doing in this joint-training?" Alphonso questioned.
"You will be learning under an expert together; after your training, you will be familiarized with the job of an exorcist where you'll be led to deal with actual terrors and problems of the world, of course, according to your level, it will be adjusted."
They nodded in understanding.
"Who will we be under? I assume it's someone noteworthy considering our standings."
Daniel said, proud of his background and bloodline.
The elder glanced at him, under the gaze of the elder, he could not help but quieten down and shrink.
"The expert is a veteran exorcist who retired from the battlefield a long time ago, he is someone who was the bane of demons in his time, he slaughtered countless demons and stood at the front. Now he has been especially invited by the clans to teach you kids so you better be respectful to him."
One of the standing elders cautioned them to not do something disrespectful, the man they had invited was not someone to be taken lightly after all.
"Who is it?" Oliver asked.
"Dennis Rivera," the elder mentioned his name finally, but all he received were confused looks from the crowd.
He sighed, it was a reaction he was already expecting, he didn't expect them to know about every valiant exorcist in the past.
While the person they invited was special, there were countless ancient exorcists famous for their exorcism and fame. So it was natural for those with lesser fame to be suppressed in the meantime.
Oliver also pursed his lips, he also had no idea who this man was supposed to be.
It was most likely a side-character since he was not mentioned in the story or if he was, then it was so insignificant that he didn't bother to remember his name.
"So, are we going to be meeting him today?"
"No, today was just arranged for you all to be familiar with one another. That's all. We will be leaving after a meeting so do whatever you want in the meantime."
With that, the group of elders left the children alone and went to discuss some important topics that definitely involved the void cloud phenomenon that happened in the Mystic Purge Clan.
