The Invincible Full-Moon System

Supernatural territory, the Demon Kingdom.

The Demon Kingdom territory is not bordering with the human's territory, they're deep inside the Supernatural territory.

There are seven Supernatural Kingdom territories that border with the human territory, the Vampire Kingdom, Werewolf Kingdom, Undead Tomb, Shapeshifter Temple, Fairy Forest, Dargonman Cave, and the Siren Kingdom.

Although their territory borders with the humans, they are wide apart.

For example, the Werewolf and the Dragonman.

They are tens of thousands of kilometers apart from each other, this makes them basically never meet except during the decennial GodKing Summit.

The Demon Kingdom territory neighbors with the Vampire, and the Undead.

Although they are neighboring each other, they are still hundreds of kilometers apart.

The Demon Kingdom is deep inside the Supernatural territory, their territory is a brazen land with no sign of life or water.

Just a barren land as far as the eyes can see.

Their Kingdom is located underground with only one way in and one way out.

The entrance into the Demon Kingdom is a huge demon mouth that is made of stone, there are two demon guards on the entrance.

They are big-humanoid demons with fiery bodies, they are bright red and have hulking bodies. Their bodies are dripped with lava that also filled their insides, huge spiky maces are in their hands.

If Rex were here, he would instantly flee after feeling the disparity between their powers.

While the demon guards are guarding the entrance, they saw a carriage approaching them from afar.

They walk forward with their fiery maces, they're unsure of what the carriage is.

Upon closer inspection, the carriage has a bloody crest on it with two big mutated beasts that look like grey crawling bats pulling it.

The beasts are galloping roughly, their feet are a blur because of how fast they're going.

The sound of the mutated beast's heavy steps was heard the closer it gets, the carriage stopped in front of the two demon guards.

A man wearing a butler outfit gets down from the carriage and opens the door politely before a pale man came out of it.

The pale man emits a horrifying bloody aura, he's clad in black gear, black robe covers his side necks as it flutters with the wind, there is a red skeleton-shaped vial strap on his body, with a black sword on his side that is the source of the pale man's bloody aura.

Without even asking, the demon guards know who the pale man is.

"King Solomon, why have you come here?", one of the demon guards asks.

Solomon glances at the two demon guards with his blazing red eyes, there are black dots that are swirling inside them.

Without even answering, his eyes flash with red energy.

The demon guards felt a huge pressure pressing on them as they fall to their knees heavily, the red energy hovers around them violently.

BAM!

The ground cracked, the demon guards can't move their bodies.

For Solomon to make two terrifying demon guards that literally guard the Demon Kingdom entrance fall to their knees speak of his power.

"Who are you two to be higher than me", he said disdainfully.

The two of the demon guards are way taller than Solomon and he seems to not like them looking down on him.

Before the demon guards can say anything, "Bring me to King Saruth"

Hearing this, the demon guards nodded their heads before the pressure from Solomon disappear.

They then guide Solomon and the other vampire inside of the Demon Kingdom.

Upon entering the Demon Kingdom, Solomon was greeted with bright red lava that lit the place in red.

There are many lesser demons crawling inside of it,

After they notice the demon guards guiding two vampires, they started to make way for them.

They are usually not this organized to even make way for people, but the aura from Solomon makes them felt frightened as they instinctively make way.

A big castle lies in the center of the place, it is big with a demonic pig symbol on top of it.

Looking at this, Solomon frowns.

"Why do I feel like this place has changed?", Solomon asks, this is not his first time going to the Demon Kingdom and he felt that it has changed.

One of the demon guards answered, "It is King Saruth command, he changed the Kingdom layout"

Hearing this, Solomon chuckles, "Let me guess, he was bored?"

The demon guards can only lower their heads, they didn't deny what Solomon said which means it is true.

While they're approaching the castle, Solomon got curious, "What did he change?"

"The Demon Castle starting from now will be a survival of the strongest, as you know we demons get stronger the more we get demonic energy. The Demon Kingdom is now divided into 8 floors, the higher the floor, the closer they are to the Demonic Eye", the demon guard explains.

Solomon nodded his head and said, "So these 8 floors can be taken by each Archdemon?"

The demon guards nodded their head, "There are seven Archdemons including King Saruth in the Demon Kingdom, and they all have their own people. An Archdemon can fight each other to occupy a higher floor"

Hearing this, Solomon glance at the symbol on top of the castle, 'The first floor is occupied by the Archdemon Beeltopheles'

Solomon knows instantly when he saw the symbol, he knows all of these archdemons because he already met with each one of them.

They skip past the castle and went behind it where there was a crimson portal.

There is an even stronger demon guarding the crimson portal, there are two black scaled womanly demons with big crescent horns and a long tail behind them.

Solomon approach them and said, "Bring me to King Saruth", he said calmly.

The womanly demons glance at Solomon, they made weird aggressive sounds before they let Solomon in.

Solomon does this six times as he went portal after portal.

He saw each of the floors with his own naked eyes and was mesmerized by it, the demons here are prospering because they're not near the human borders.

Unlike the Vampire Kingdom, they must always be alert because of the human skirmishes.

Every time they meet humans skirmishes, they almost always suffer casualties because of the encounter.

Solomon and the butler vampire were quite shocked when they're on the sixth floor, the demons here are at least peak rank five and above.

What makes them shocked was because how many of them.

They're numbering in the hundreds, making them an unstoppable force but all of them seem to be hibernating.

The sixth floor was occupied by Archdemon Lucius, he was strolling around when he saw Solomon.

"King Solomon, what are you doing here little vampire?", he said pridefully.

Lucius is a ten-foot Archdemon with razor-sharp teeth, his frame is huge especially adding the huge demonic wings on his back. His muscular body looks unnatural with a huge saber on his hand.

His muscular hind legs make the ground crack each time he steps, his demonic energy is rampaging around him freely pressuring his surrounding.

Even the Vampire beside Solomon hardly stands his ground.

Solomon smirk, "Isn't it Lucius, I'm impressed you manage to beat the other Archdemons with that tiny demon brain of yours", he said mockingly.

Hearing this, Lucius approach and stopped in front of Solomon.

ROAR!!

He roared menacingly right in front of Solomon's face, saliva came out of Lucius's mouth but got blocked by a red barrier around Solomon's body.

Solomon is not fazed by Lucius' roar, he even chuckled a bit because of it.

"Don't forget that you're in our territory", Lucius said brutally.

Solomon only smiles mockingly, he doesn't mind Lucius' behavior because he has the power to back it up.

Lucius' demonic aura is attacking Solomon openly, he looks like he wanted to fight with Solomon.

Looking at this, Solomon can only raise his hand signaling to stop, "I don't have the time to play with you, I'm here to see King Saruth"

Hearing this, Lucius take back his aura and scoffed.

"King Saruth already knows of your presence", he said while he makes way for Solomon.

Right before Solomon wanted to go inside the portal, he then realizes, "Wait, I thought there are only seven Archdemons, Why are there eight floors?"

Lucius glance at him, "Just go to the crimson portal, ignore the dark blue portal"

Solomon got curious but he shrugs it off, he came here for a reason so he will just try to find out about it later.

He saw the dark blue portal just beside the crimson portal, it roughly emits the same amount of energy with the crimson portal leading to the eighth floor where Saruth is.

Just as Solomon wanted to get in the crimson portal, a terrifying creature suddenly emerges from the dark blue portal.

The creature's body is black charcoal with blue sharp eyes, its elbows are sharp with a blue glowing rune on its chest. Its horn is spiky and thick, there is a black spear on the demon's hand that is blazing with blue fire on its tip.

Solomon jumped away instinctively, 'What? What happened?'

The Vampire beside him was also shocked, he didn't expect Solomon to jump away suddenly.

'What is this? My body felt danger? You're telling me this demon can potentially be on my level?', Solomon thought in shock.

As a Vampire, his danger sense is heightened to its max.

His body can tell which creature can potentially hurt him, it is his natural instincts as a Vampire.

Even when he met Lucius before he didn't felt threatened, even though he is the strongest Archdemon second only to Saruth.

'This demon is at least as strong as King Saruth', Solomon thought.

The black demon was also surprised to see Solomon, "Vampire? I'm sorry to have startled you", he said politely.

Hearing this, Solomon gets back to his cool, "I never know you before, who are you?"

Lucius also came flying from Solomon's back, he was also shocked to see the black demon out of the dark blue portal.

"I was told that you're strong and I wanted to fight with you, but not anymore", he said wryly.

The black demon's presence instills fear in his entire being, he can't believe that there is another demon who is as strong as King Saruth.

The black demon's aura is pure black, its blue eyes make Lucius lower his gaze.

Looking at this, Solomon was confused, "You don't know this demon Lucius? How come you didn't know him?"

Lucius was also confused about how to explain it.

Before he can even answer, the black demon intervenes, "King Saruth is waiting"

Solomon and Lucius glance at the black demon in a union, they both felt overwhelmed by the black demon's appearance.

It is quite an unexpected surprise for Solomon, he didn't expect to find this black demon here.

King Saruth himself has a high chance of beating Solomon.

Vampire's power relies on blood and demons don't have any, they're the natural counter for Vampire because of this.

'Where did that prideful demon found this black demon? Did he did something behind the other Supernatural backs?', Solomon thought with a frown.

While he's thinking, Lucius said, "This Vampire here is Solomon, the King of Vampire"

Hearing this, Azzen nodded his head and gave a slight bow to Solomon.

Solomon was shocked, he didn't expect Azzen to be this humble judging from his power.

"I'll be meeting King Saruth then, don't disturb us", Solomon said, he felt weird for someone like the black demon to be respectful in front of him.

Seeing the black demon's slight bow, Lucius becomes more awkward.

The black who is definitely way stronger than him is kneeling in front of Solomon, while he on the other hand roared in Solomon's face.

"Then I'll be going now", he said before he walks past Solomon and Lucius.

Solomon nodded his head and went inside it, 'Seems like Saruth need some explaining to do'
