"It's only possible to enter but not to exit. What does this mean?"

Merlin and Setoh's faces turned ashen. They did not wish to be trapped in the Flare Region world for countless years or they would be unable to visit the Giant Tribe to help the Spell Caster civilization. The consequences would be unthinkable.

Flarite looked up with a bitter smile. "You've heard earlier that the entire Flare Region world is a prison to detain the Vestigial Tribe! This prison is incomparably solid. Whether from outside or inside, it's nearly impossible to exit. If a prison allows one to go out easily, what kind of prison is it? Of course, Sir Flare Emperor had said that the exception would be those ultimate existences who could sense the traces of the natural order left here. They might still be able to break free from this prison. However, from the looks of it, you're not ultimate existences, right?"

The Flare Region world was a prison made to lock in the Vestigial Tribe. Other than ultimate existences, no one would be able to break free from it. With this thought, Setoh raised his head abruptly, and Darkness Maxim swiftly gathering over his body.

Merlin did not stop Wizard Setoh when he saw what Setoh was doing. He might as well let Setoh give it a shot, to see if it was as impossible to leave the Flare Region world as Flarite had said.

"Open!"

Setoh waved his hand, and the terrifying Darkness Element turned into a darkness giant. It grasped with both hands at something and tore it apart furiously.

If this was an ordinary dimension, a tear like this would easily split the dimension apart. Nonetheless, the Flare Region world merely gave a small shudder. The breeze brushed past softly, and nothing changed.

"Why is it like this?"

Merlin's expression turned cold. He saw that Wizard Setoh was unhappy as well. They were trapped in the Flare Region world.

"How about that? I wasn't lying, right? I wanted to leave this place. It's been so many years. Even though we have orders from Sir Flare Emperor, who would stay here? During these years, the world that was initially barren gradually gave birth to living creatures, even developing into a civilization. We've witnessed the glory and decline of many empires, even the golden era of this world. However, no matter what, we can't change the fact that this is a prison, and we can't get out…"

Flarite's tone was despondent. It was not that he did not want to leave. Conversely, no one would want to stay here after being in this place for so long. They wished to leave too.

However, this was a prison designed by the Flare Emperor of the Thirty-six Emperors. How could they leave so easily? Back then, the three of them who were selected did not plan on leaving. Even so, after an extensive passage of time, even the strongest resolve would waver.

"There must be a way! Flarite, as sentinels of this prison, where is this prison exactly?"

Merlin looked up and fixed a gaze on Flarite as he asked carefully.

"The prison's exact position? This entire dimension is a prison. For instance, you are trapped in here, and can't go out. This is the prison!"

Flarite's words helped Merlin understand that the entire Flare Region world was a natural prison. They were swept into this world, and could not get out.

"Then how do you control this prison? As sentinels, you may have some special methods to control it. Otherwise, why would the Flare Region world suck us in?"

Merlin did not buy into Flarite's excuses. Perhaps Flarite was mainly speaking the truth but he must have kept some things to himself. The way they were swept into the Flare Region world, for example, was something a prison would not do.

Flarite's expression was one of embarrassment as he explained in a low voice, "Alright. There's no issue telling you now since there's no Vestigial Tribe in this prison, and they've vanished anyway. To be honest, you were sucked in by the Flare Region world because some small mishaps had occurred throughout the years. Not even I can control it…"

"Mishaps?"

"That's right, mishaps! Initially, the Flare Region world wouldn't engulf you in that manner but as more time passed, I kept trying to leave the Flare Region world every day. Therefore, this caused some small mishaps, and the entire Flare Region world would explode with immense power irregularly. This is the power of the entire prison, and anyone below ultimate existences would be unable to escape! Unless the power of the natural order is involved, anyone would be swept into the Flare Region world."

Flarite was rather embarrassed. He wanted to leave the Flare Region world too badly but unintentionally caused more issues. Not only was he still unable to escape but he had also triggered the function of the prison, which constantly "capture" people.

Merlin and Setoh were such sacrifices!

Merlin knitted his brow. He thought about the Slothful Beast. This was an existence beast which the three Arcane Wizards could not handle, yet it was sucked into the Flare Region world.

"Although the Slothful Beast is powerful, it can't mobilize the power of the natural order. It can only move by instinct… That's right, Wizard Merlin, we can use the Slothful Beast!"

Setoh seemed to have thought of a plan, and his eyes shone.

"That's right. The Slothful Beast is very strong. Can it break out of this prison?"

Merlin's eyes gleamed as well. They thought of the Slothful Beast. Nonetheless, it was difficult to manipulate the Slothful Beast because it would not become enraged. The Slothful Beast would not pay any attention at all using ordinary methods.

Just like how the three Great Arcane Wizards had attacked the Slothful Beast in the past but the Slothful Beast did not care at all, and the three Arcane Wizards could do nothing. This time, Flarite had tried to use various techniques of attacking the Slothful Beast but it still did not react.

Merlin thought about it for a moment, then told Flarite, "Bring us there for a look since it's an area under the sentinels' control. Since you're sentinels, you're surely able to control the Flare Region world. I'm guessing you've exploited that factor to try and leave this world."

"That's right, that's what I did. However, it's too difficult to leave… I'll take you for a look!"

Flarite did not refuse and immediately stood up. He softly delivered instructions to the man beside him, following which the man took his leave first, probably to make preparations.

"Both of you, please follow me!"

With that, Merlin and Wizard Setoh followed behind Flarite, heading outside. After a short moment, that man had joined Flarite once again, bringing with him a woman whose force Merlin had previously detected through his Mind Power. She must be a sentinel of the sacred land as well.

"I forgot to introduce to you. These two are sentinels as well. Back then, Sir Flare Emperor had arranged for them to assist me in guarding this prison."

The man was called Flaraoh and the woman was called Flarmun. They were both comparable to Lords, which made Merlin and Setoh endlessly astounded. It was not surprising that they were able to guard this massive prison.

The Flare Emperor spared no expenses, sending three Lords to act as sentinels!

"Alright, this is the heart of the sacred land. There's another name for this place, called the Limbo Prison. It's simple – although the entire Flare Region world is a prison, if someone comes in here and stir up trouble, then us sentinels will have to do our jobs. We'll capture them and throw them into the Limbo Prison. As the name suggests, the Limbo Prison will put one in a state akin to limbo. Very few people, other than ultimate existences, will be able to bear that torment."

As Flarite explained, he revealed some apprehension toward this Limbo Prison.

Merlin looked ahead. Indeed, there was a huge, open space before them, burning with unceasing light blue flames that surged turbulently. Just the force of the blaze alone induced a sense of extreme danger in Merlin.

"Hiss."

Merlin condensed a flash of Darkness Maxim that instantly blanketed the sea of light blue flames. However, in the blink of an eye, Merlin's Darkness maxim was reduced to ashes.

Merlin's face changed slightly. Even an ultimate Maxim was burned to ashes. This light blue blaze was truly incomparably frightening.
