Reborn As A Ghost: Time To Build My Undead Army!-Chapter 1879: Lucifer VS Sirius

-----

"I despise my father for being a man too obsessed with face, appearances, society, and how others viewed Vampires, instead of truly caring for his family and doing what was best for them—even if it cost the lives of others," Sirius said, glaring down at Lucifer. "My father was a fool, and it seems you are one as well. I had hoped we could all become allies. Dragons are, after all, the original inhabitants of this world… but it appears you have no such intentions."

Sirius' aura radiated with tremendous malice, shocking Lucifer. He wasn't wrong—the innocent child he once knew was long gone, replaced by a true monster.

"Hah…" Lucifer clutched his face as tears slipped from his eyes for a moment. "I was truly the fool here, thinking I could change you with a few words… I see how it is, Sirius. You're completely broken now."

"How many people have you killed?" Lucifer sighed. "Thousands? Millions?"

"Maybe," Sirius replied. "I don't really count them. I have simply followed my instincts instead of suppressing them like my foolish father, who led his family to ruin. Now then, I am growing bored of this talk. Will you stand aside, or will you stand in my way, Sir Lucifer?"

"…"

Lucifer's aura surged with all his immense power. He looked at Sirius with eyes blazing in conviction and determination.

"For your father, I will stop you, Sirius," he said, summoning a giant blazing scythe.

"I believe that won't be necessary," Sirius said, his fists surging with blazing blood energy. "I trained without end so that when this day finally came… nobody would be able to stop me."

"WELL, I WILL!"

RUMBLE!

Lucifer's scythe clashed against Sirius' fists. Explosions of blood energy and void flames erupted, yet Sirius appeared almost unscathed.

"I see—so you also have immunity to fire, Sirius?" Lucifer asked with a smirk.

"That, I do," Sirius nodded. "However… your flames contain an element I don't recognize…"

"Yes, that's void," Lucifer smiled. "I believe you gained immunity—and even absorption—for most elements you could actually find and summon with magic… but void is something few could ever locate, and it is not present in the world the way you believe!"

CLASH! CLASH! CLASH! CLASH!

Lucifer didn't rely solely on his scythe. He unleashed barrages of powerful fists, kicks, and tail whips, surprising Sirius with his constant use of martial arts—techniques Lucifer had absorbed, learned, and refined into his own unique style.

"That's quite right," Sirius said. "You are not wrong at all. Void is the most elusive element of them all. Unfortunately, I was only able to attain Void Resistance at Level 10."

"…?!"

And then Lucifer watched Sirius walk straight through his flames, reach his face, and unleash a single devastating fist that pierced his skull and blew his brains out.

"{Heaven-Collapsing Scarlet King Fist Arts}: {First Form – God-Slaying Blazing Demon Fist}!"

BOOOMMM!!!

A massive explosion of flames erupted and scorched through Lucifer's head. His brains exploded outward and fell to the ground while his headless body stood completely immobile.

"Is he dead? His soul is not… wait."

Sirius' eyes widened as he saw Lucifer's fist rushing toward him a second too late.

An explosion of pure Aura, Ki, Dream Essence, and Mana surged from the dragon claws, tearing through Sirius' thick Consciousness barrier—as ridiculous as that sounded.

CRASH! CRASH! CRASH! CRASH!

"Hah, magnificent. I couldn't expect anything less from Maria's henchman!"

Sirius evaded the next series of attacks while darting through the empty air, then released giant bat-like spirits from his punches—literal manifestations of his own Soul and Martial Intent.

Lucifer's momentum was interrupted as he regrew his head, only to find dozens of enormous bats swarming him, biting into his body, draining his blood, and feeding it directly to Sirius.

"Hm, the blood of a white dragon! It truly burns the palate, yes!" Sirius said, overflowing with even greater power than before. "But that's exactly why I must continue partaking of it! You will become the source of my power!"

"ENOUGH!" Lucifer roared. His aura obliterated the surrounding bat monsters and then struck Sirius as his massive Martial Soul manifested.

"So you too have a Martial Soul!" Sirius said. "Have you obtained your seventh yet?"

"…What?!" Lucifer's eyes widened. "S-Seventh?!"

TRUUUM!

And in front of Lucifer, Sirius manifested not one, not two, not even six—but seven different Martial Souls, surpassing even the number held by the Heavenly Emperor!

Each of Sirius' Martial Souls resembled a giant crimson knight wielding a different weapon. They were his personal knight table, and each one attacked Lucifer as he swung his fists.

"All seven of my Crimson Knights have been waiting for this moment, polishing their weapons for hundreds of years!" Sirius roared, clashing against Lucifer and immediately overwhelming him!

"H-How strong has he become?! How is this possible—AAAGH!" Lucifer screamed as he was driven downward into the city below. Dozens of houses flattened beneath his massive body.

CRAAASH!

"Well, Sir Lucifer?"

"…!"

Lucifer looked up at the sky with eyes full of disbelief and shock at the power radiating from Sirius.

This man had been concealing such tremendous strength the entire time!

If he had ever dared to intervene and fight them before Maria and everyone else took that journey through the tower…

"Not even Maria would have survived…!"

"Will you continue opposing me, or will you finally give up?" Sirius asked. "With your talent… I would not mind welcoming you to my family. You could become our very first Vampire Dragon. I would swear to protect your family and assign you a territory once Yggdrasil becomes mine. So, what do you say?"

"Hah… I am grateful. Despite how broken you are, you can still show mercy and kindness, huh?" Lucifer closed his eyes and smiled before slowly standing up, careful not to crush anyone. Fortunately, Maria had been evacuating most of the city at incredible speed; half the population was already gone. "But I must decline."

"…Why?" Sirius asked. "Why decline such a great offer? In this way, both of our factions would gain something, and nobody would lose anything."

"It doesn't work like that, young Sirius," Lucifer's aura suddenly shifted.

"Hm?" Sirius' sharp eyes detected an anomaly he had never seen before. "White… and Black?"

Yin and Yang surged from Lucifer's body. His white form transformed, half became radiant gold, the other pure black.

Half of his being embodied life, the other death!

Abyssal Death Flames.

White Void Flames.

Both combined, swirling together in perfect harmony.

"After training for over a year, I finally achieved this. I show you now my strongest form… Sirius!" Lucifer roared, his power surging hundreds of times higher than before. "Complete Harmony!"

"Hoh…" Sirius looked genuinely amused. "Interesting. You have only become even more valuable… I will make sure to kill you now. Then I'll tell Annette to revive you as an Undead."

"Maybe I don't have the talent to possess seven fucking Martial Souls, but I have poured everything I had into my own," Lucifer said. "Look!"

RUMBLE!

Lucifer's Martial Soul expanded a hundred times larger, resembling a colossal titan towering above the city!
