Vampire Overlord System in the Apocalypse

-----

As Noah's party kept devastating everything while slowly approaching the immense castle several kilometers away, their group spread far and wide and fought any monsters that came in front of them with utmost ferocity.

However, after killing hundreds of monsters, a Hidden Boss was triggered, the Accursed Tree King.

Referring to the entity that inhabits the castle as his "Lord" he acted like a loyal subordinate, proud of his own strength and showcasing utmost power, managing to overpower Adamantine after a few hits!

Angered by how she ravaged his kin, he intended to end her with a series of whip attacks using his special ability, Soul Fire Whip, which was able to deal direct damage into a foe's soul!

However, it wasn't as if others were not able to notice what was going on, and Iris was the first to come, confronting the powerful Hidden Boss with her Blue-colored nether Flames, which seemed to be able to easily dissipate the Accursed Tree King's purple-colored Soul Flames!

BOOOOM!!!

The Accursed Tree King felt shocked as his powerful Soul Fire Whip was destroyed by the blue flames!

The Soul Flames were his special Ability and Magic, the one he had been born with thousands of years ago, which he had trained since then.

Through his entire life, he had never faced someone that could actually make it dissipate like this!

However, after he and his lord alongside their vast territory were suddenly trapped in a strange space-time disturbance, invaders from another world emerged, which he intended to destroy and survive…

Perhaps if he had confronted conventional Hunters, he would have been able to easily crush them… but against Noah and his subordinates… an easy victory was impossible.

"This… Impossible! My Soul Fire has no match! How…?!" asked the Accursed Tree King, seeing his Soul Fire being destroyed so easily actually shocked him deeply!

After fighting with it for thousands of years, he grew way too confident on it!

To think that this day was the fateful day he would finally meet someone with a flame similar to his…

"Do you think I would let you kill my dog in front of me?" asked Iris, glancing from above, as she floated while being shrouded in blue flames. Atop her head, there were two large fox-like ears and nine fox-like tails growing from her back. Her arms were coated in this phantasmal will-o-wisp, shaped as large claws, and her nails extended sharply while secreting a deadly venom.

Her gleaming crimson eyes shined brightly and eerily, glancing at the Accursed Tree King from above as if she were glancing an insolent animal…

The Accursed Tree King recognized her gaze immediately, as he had fought against many armies in the past and had taken the life of many Demons, he knew the different expressions of cold-hearted people.

But this gaze… was like that of someone that didn't even recognize him as a foe!

What was this?

Didn't he just almost killed her companion?

How could he not be seen as a threat?

Deep within his old soul, the Accursed Tree King felt boiling anger!

His crimson eyes began to flash, blazing with purple Soul Fire, as his arms grew sharper and more malefic!

However, instead of roaring in anger, he laughed as he smiled while frowning, the wrinkles all over his face made him look even more intimidating!

"Gahahaha! Good! It wouldn't be worth it if you weren't strong! Let me tell you that I have taken the lives of over 20 Demon Generals in the past in the name of my Lord Beelzebub!" he said, as his bark was shrouded in purple flames, and his humanoid-like body gained more mass and became even tougher!

Iris glance at him rather expressionlessly, as Adamantine finished healing herself and jumped to her side.

"Mistress, he's strong!" said Adamantine, mildly concerned.

"I know… Let's give my love a good show, alright, Ada?" asked Iris.

"Yes!" said Adamantine, while waving her shadow tails.

"(She recovered incredibly quickly! Just a few seconds ago I had her to my mercy…! And the one that arrived didn't actually do anything to help her… Just how fast do they regenerate? These beings are truly like the Blood Demons!)" thought the Accursed Tree King, as he decided to fight ad surprise them with an unpredictable move!

"Soul Flames Tower!"

The Accursed Tree King pushed his roots into the ground, as he unleashed Soul Flames into it and then generate an enormous tower of purple flames right below Iris and Adamantine a second after!

BOOOM!

Iris and Adamantine were not able to react in time due to his unexpected attack, and they were consumed by the flames!

"Hah! This one never fails to surprise the young folk…!" laughed the Accursed Tree King, he seemed to be experienced in taking away the life of arrogant younglings.

Flash!

As the flames dissipated, the Accursed Tree King's smile dissipated immediately after.

A large sphere of blue flames remained within it, as Iris and Adamantine survived the powerful attack like nothing!

"I knew it, my Phantasmal Flames seem to be able to do well against this purple fire…" analyzed Iris, as she suddenly generated dozens of weapon projectiles in the form of long blades made of phantom blue flames, flashing towards the Accursed Tree King!

FLASH! FLASH! FLASH! FLASH!

"Unfazed…! This woman is ridiculous!" thought the Accursed Tree King, as he waved his large hands and generated several projectiles made of his own hardened black bark, shaped as giant spears of wood!

FLASH! FLASH! FLASH! FLASH!

Both projectiles meet in midair, crashing against each other into cloud explosions!

BOOM! BOOM! BOOM! BOOM!

Iris smiled, as she decided to use this opportunity to infuse a lot of mana into her body, darting towards the Accursed Tree King with great speed!

FLASH!

The Accursed Tree King, however, predicted her move and laughed.

"I knew you would try to do that! Soul Flame Black Spear!"

Combining his incredibly hard, black-colored bark with his soul flames, the enormous ancient tree monster unleashed a gigantic, building-sized spear coming directly out of his very body, targeting it towards Iris!

"You may be able to dissipate my Soul Flames, but not my bark!"

As the enormous spear reached Iris, the Accursed Tree King already imagined her getting impaled by it to death!

However, Iris waved her claws.
