Strongest Necromancer Of Heaven's Gate

Eligor's plan was simple.

Attack the entrances that were used by Agarthians in order to enter their underground Kingdom.

He had already gained information from a King of a Kingdom that was affiliated with Agartha.

Of course, the King didn't give away this information on his own accord.

That would've been impossible.

Eligor extracted this information directly from the King's Soul, reading all of his memories like reading a book. This was also why he had proposed that all Demigods temporarily withdraw their offensive against the Dragons and the Elves, shifting the focus on Agartha.

He believed that it would be easier to capture the Ancient Kingdom, which only had three Supremes as its Guardians.

Aside from King Septimius, there were two more Supremes that protected Agartha, keeping it safe from outsiders.

Still, the Fallen Angel wasn't worried. Their side had fifty Demigods who would join him in this invasion.

The armies under their command numbered in the millions, and with this, he was certain of their victory.

But just as he arrived at the location where the entrances of Agartha were located, they couldn't find them.

In order to prevent their enemies from easily reaching their kingdom, King Septimius ordered that all the entrances that led to Agartha must be destroyed, sealing them off completely.

Knowing that their Kingdom's future was at stake, the Agarthians took this order critically and ensured that not a single entrance remained open after they were done.

When Eligor and the other Demigods realized what King Septimius had done, they couldn't help but applaud him for his decisiveness.

However, they weren't deterred.

The Abyss was a place where only the strong survived. There were several Abyssal Creatures whose specialty was to dig underground in order to hide and hunt their prey.

These monsters had joined their Abyssal Lords to conquer Elysium, and they numbered over a hundred.

"Dig and unearth these entrances!" Eligor ordered. "We'll show them that their move did nothing but delay the inevitable."

The Abyssal Monsters who specialized in digging immediately went to work.

Since they could sense the layout of the land underground, they were able to follow the destroyed tunnels that led to Agartha.

A week later, a couple of the pathways that led to Agartha had opened up, and the Abyssal Army finally started their march to conquer the Ancient Kingdom of Elysium.

Royal Palace of Agartha…

"They are coming," King Septimius sighed as he opened his eyes. 

"Good," one of the two Supremes, who protected Agartha alongside the King, commented. "Fortunately, we managed to delay their invasion by a week. Our defenses may not be perfect, but they will hold."

"Indeed," the other Supreme nodded his head. "We will show these monsters that we are not pushovers."

King Septimius smiled before rising up from his throne. 

A moment later, he reappeared several miles outside his city and looked at the hundreds of gaping holes that the Burrowers of the Abyssal Army had dug.

He could sense the powerful presence of the Demigods who were leading their armies to conquer his lands.

A faint sneer appeared on King Septimius' lips as he raised his scepter.

The Defenders, who had formed a defensive wall and were two miles away from where the Abyssal Army would appear, prepared themselves for the eventual battle that was about to commence.

High above their heads, a Gigantic Flying Bone Ship hovered, similar to a Flying Fortress that was born for war.

"Ready!" Eiko shouted. 

Immediately, the Skeleton Swashbucklers went to their respective positions, preparing for battle.

The Ancient Pirate King, Avery, stood beside Eiko with his arms crossed over his chest. The flames burning in his eyes burned bright, ready for battle.

Poseidon had also revealed the countless cannons in its body, ready to fire at Eiko's command.

The Baby Slime looked in the distance with a calm expression on her face. She didn't feel any fear. 

On the contrary, she was looking forward to the start of the battle, thrilled that she wouldn't be fighting alone.

Standing at the deck of her ship, Lux looked in the distance with arms crossed over his chest.

Asmodeus, King Leoric, Avernus, and Andras were by his side, ready to fight under his command.

Now that Lux had become a Saint, his Named Creatures had also grown a lot stronger. They were creatures that grew alongside him, which meant that the stronger he was, the stronger they would also be.

Currently, Asmodeus and King Leoric were of the Calamity Rank.

Avernus and Andras, on the other hand, had stepped into the Ranks of Demigods.

Along with Eiko's forces, the number of Demigods on their team alone numbered four.

But that was only including those who were present on the scene.

Blackfire hovered behind Lux, and it was very excited to show its Master the latest additions to its personal army.

It had accompanied Hereswith in fighting against the Demigods who had attacked Espoir Frieden. 

Because of this, it managed to devour ten Demigods, as well as hundreds of Calamity-Ranked Monsters.

All in all, Blackfire could summon twelve Demigods, excluding Hereswith, who was protecting the World Tree of the High Elves.

The eleventh Demigod was none other than Andras, who had transformed into a Strigoi.

The other one was the Demigod, Briarz, who had arrived alone in the Six Kingdoms and found himself dying a pitiful death.

Blackfire didn't bother to change the abyssal creature's form because the four-meter-tall Blue Minotaur was already imposing enough. It deemed that simply reviving him as he is was good enough.

"They're here," Lux said in a solemn tone. "Eiko, give them a warm welcome."

Eiko nodded. "Go! Poseidon!"

The countless cannons of the Giant Bone Ship started to glow. The moment the Abyssal Monsters spilled out from the holes to start their invasion, they found themselves staring at countless beams of light that vaporized anything they hit, not even leaving ashes behind.

The Agarthians cheered after seeing Poseidon's might, raising their morale to its peak.

Even King Septimius couldn't help but nod his head in satisfaction as the first wave of Monsters that had come to conquer his lands were annihilated before they even knew what hit them.
