The Demon Kingdom was located in the Demonic Impure Land.

The Demonic Impure Land was infamous for being the seventh forbidden area in Fantasia.

Although it was only the seventh and the weakest forbidden area, it still was a forbidden area that weak living beings dared not enter.

Those with weak will would be eroded by the demonic miasma constantly released by the land in the Demonic Impure Land.

For normal living beings in Fantasia, the demonic miasma would erode their mind and body and even affect their soul. It would cause them to demonize and lose their sanity.

However, for natural-born demons or those living beings born from a demon race, the demonic miasma was like a tonic for them.

The mana in the Demonic Impure Land already consisted of 90% demonic miasma and 10% elements so it's no longer a pure mana. Because of that, only those from the demon race could thrive in the Demonic Impure Land and it was the forbidden area that other races couldn't inhabit or else they would be eroded by the demonic miasma.

The top powerhouses in the world had yet to know the reason for the existence of the demonic miasma in the Demonic Impure Land and it was said that the seven forbidden areas existed since the birth of this world.

At least, even the Dragon King and the Primordial Spirit of Chaos had already seen the seven forbidden areas existing since time immemorial.

Even Zanna barely knew anything about other forbidden areas, especially the Broken Sanctuary which was the second forbidden area.

If the other forbidden areas could be explored, the Sea of Chaos and the Broken Sanctuary couldn't be explored by normal means.

The Sea of Chaos could only be resisted by those who had resistance or had mastered the chaos element.

On the other hand, the Broken Sanctuary was even more mysterious than the Sea of Chaos.

If the outside world knew that the Sea of Chaos was filled with chaotic world laws and falling too deep into the Sea of Chaos would destroy them, then the Broken Sanctuary would make them lose themselves.

Those who entered the Sea of Chaos would die and couldn't be resurrected by resurrection magic. While those who enter the Broken Sanctuary would lose their memories and at worst, even lose their power.

There were even worse cases where those who entered the Broken Sanctuary couldn't return to the outside world. It was as if the Broken Sanctuary was a separate realm from the World of Fantasia.

Even with hundreds of thousands of years of age, Zanna had yet to step foot in the Broken Sanctuary.

She can indeed swim and dive in the Sea of Chaos as if it's just a normal sea. But the Broken Sanctuary was different as even she felt that it was more dangerous than the Sea of Chaos.

The only reason why the Broken Sanctuary wasn't the most dangerous forbidden area was due to the possibility of returning to the outside world in one piece even after entering the Broken Sanctuary.

However, those who entered the Sea of Chaos would die if they didn't have resistance to the chaos element.

Even grand-level powerhouses couldn't stay in the Sea of Chaos for far too long or they would die. After all, the chaotic waters in the Sea of Chaos would erode and siphon a grand-level powerhouse of their mana and aura until they could no longer use the mana and aura to protect themselves.

In the entire World of Fantasia, only Alister and Zanna could swim and dive in the Sea of Chaos as if it were nothing but normal seawater.

The Sea of Chaos despite being the most dangerous forbidden area was still simple and didn't have any veiled mystery. At least, the outside world had already seen through the secrets of the Sea of Chaos but even if they did, they couldn't make use of the Sea of Chaos since only those with affinity to the chaos element could train in the Sea of Chaos.

However, the Broken Sanctuary was veiled with mystery as even the Dragon King and the Primordial Spirit of Chaos hadn't seen through its secrets yet despite being the oldest top powerhouses in the World of Fantasia.

Those heroes from past generations who had entered the Broken Sanctuary out of curiosity had also died and disappeared from the world.

As for the Demon King, none of them could leave the Demonic Impure Land even if they wanted to. They couldn't leave until all nine heroes were dead.

In history, it has been very rare for a Demon King to be able to leave the Demonic Impure Land. Since in most cases, even if a hero was dead, at least they could still manage to defeat the Demon King.

But even if a Demon King managed to leave the Demonic Impure Land, it's not like the other major races were passive.

For example, one of the strongest Demon Kings in history was beaten up and defeated by Zanna. The only reason she made a move and fought against a Demon King was due to the heroes failing to defeat the Demon King.

With the death of the nine heroes and the Demon King being liberated from the curse bestowed upon him by the Goddess of Fantasy, Zanna took action and sealed the Demon King.

However, even if a Demon King managed to leave the Demonic Impure Land, they would only have one thousand years of freedom.

After all, every one thousand years, a new batch of heroes would be summoned and usually, a new Demon King would replace the deceased Demon King.

What if the Demon King didn't die but instead, the nine heroes died?

Well, the Demon King would be forcefully reused after a thousand years. Even sealing the Demon King wouldn't prevent the Demon King from being forcefully teleported back to the Demonic Impure Land.

That guaranteed that if the new generation of heroes defeated the Demon King, there wouldn't be a need to reseal the Demon King again.
