Unlike the barrier or extensibility of the Particle Release Jutsu, the Shadow Greatsword, directly enveloped in a hazy white barrier, instantly pierced through the Black Dragon Monarch's chest scale, following the sword wound left by the hero. It tore through—no, it completely split the Black Dragon's Heart in half. Then, with a 'boom', it shot out from the other side of the Black Dragon Monarch's body and plunged into the valley ground.
From beginning to end, even the mighty body of the Black Dragon became as fragile as tofu under Naruto's Dust Release.
"Roar—!"
The sleeping Black Dragon Monarch, as if experiencing a final burst of life, suddenly raised its majestic dragon head and let out a mournful, earth-shattering roar that echoed through the valley, shaking the night sky for dozens of kilometers around.
With a loud 'thump', the Black Dragon Monarch's mighty dragon head slammed heavily onto the ground, kicking up a cloud of thick dust.
The Black Dragon Monarch… died.
However.
No system pop-up appeared before Naruto's eyes, indicating that the Black Dragon Monarch's death was not judged by the Underground City as a successful kill. Otherwise, Naruto could exploit this bug to infinitely farm experience.
Clearly, the system wasn't that foolish.
But it was also clear that Naruto wasn't after the Black Dragon Monarch's experience points; he was after…
Subduing the Black Dragon Monarch!
"I need to revive it before the World Will of the Goblin Slayer World descends and revives the Black Dragon Monarch."
A sharp glint flashed in Naruto's eyes.
Slaying the sleeping Black Dragon Monarch was just an appetizer.
The main event was next.
Naruto's haori flapped, and the dark crown on his head appeared without him noticing.
He was like the Shadow Monarch, descending upon the world, exuding unparalleled majesty and pressure. His azure eyes revealed an indescribable coldness and dominance.
"Arise, awaken, my loyal servant! I shall grant you new life with 'Shadow'!"
"Black Dragon Monarch—!"
Naruto extended one hand, his five fingers pointed at the Black Dragon Monarch, and clenched it fiercely.
It was the Shadow Monarch's power… Absolute Dominion!
Immediately, the dark shadows covering the land in all directions seemed to find their destination, rapidly surging towards the Black Dragon Monarch in the center.
Large amounts of shadow drilled into the Black Dragon Monarch's body, covering its wounds, reshaping its flesh, condensing its soul, and transforming it into an "Shadow" that would absolutely obey Naruto.
At the same time.
Naruto waved his hand, and all the surrounding Mithril jars poured out Dragon Blood.
An immense amount of Dragon Blood continuously poured into the Black Dragon Monarch's Black Dragon's Heart wound. A powerful and scorching life force, like a seed breaking through the soil, quickly took root, sprouted, and grew vigorously. With each heartbeat, it was pumped throughout its entire body.
The Black Dragon's Heart was completely revived.
"Thump-thump—thump-thump—thump-thump—"
The powerful heartbeat of the Black Dragon's Heart echoed throughout the entire Dragonfall Valley.
The Black Dragon Monarch's heart and flesh wounds healed and regenerated at a visible speed. The thin, tattered membrane of its dragon wings quickly recovered, and even the severed dragon horn on its head grew back.
A vast, fierce, and incredibly powerful aura erupted from the reviving Black Dragon Monarch.
It was clearly several times stronger than Dragon Mother Tiamat!
"Hiss."
The Black Dragon Monarch suddenly opened its heavy eyelids, and as its eyelids flipped, a pair of dark golden vertical pupils stared indifferently at the world. Its gaze was like a solidified beam of cold light, illuminating the dim valley.
The Black Dragon Monarch—had awakened!
It suddenly raised its head, its majestic dragon head pointed towards the Red Moon and Green Moon in the night sky, and let out a deafening roar.
"Roar!"
The deafening dragon roar echoed for dozens of kilometers around. The true dragon's might caused all living beings, all creatures, to prostrate themselves on the ground, trembling, none daring to make a sound.
"Good, very good."
Naruto clapped his hands and nodded in satisfaction.
The stronger the Black Dragon Monarch was, the happier he was.
Because the Black Dragon Monarch was now his "Shadow"!
At this moment, a high-energy magic reaction appeared within the Black Dragon Monarch's body and quickly gathered in its throat.
The Black Dragon Monarch opened its mouth and spewed out a destructive beam of light with dark purple edges, sweeping out from Dragonfall Valley. It plowed through hundreds of kilometers, creating countless explosions and leaving behind terrifying, bottomless ravines flowing with scorching lava.
It was as if a volcano had just erupted.
The destructive power of the Black Dragon Monarch was terrifying.
If not for the hundreds of kilometers around being uninhabited Gobi desert, this single blow alone could have cut through the Wind Capital and Water Capital like a small cake, back and forth.
How could such a weapon of war from the mythical era, capable of threatening even the existence of "Gods," be resisted by humans?
Having vented the depression of a thousand years of slumber, the Black Dragon Monarch closed its mouth, spread its wide and heavy Dragon Wings, and flapped them fiercely. A strong wind swept through Dragonfall Valley, sending boulders rolling, and its massive dragon body actually lifted off the ground, carrying countless dust and dirt, causing the nearby cliffs to collapse.
The Black Dragon Monarch flew towards Naruto in the high sky.
Naruto looked at the approaching behemoth without any fear, only smiling and saying, "Quite the morning temper."
The Black Dragon Monarch, approaching with great momentum, made no other movements, merely lowering its proud dragon head to swear its absolute submission to Naruto.
"Good."
Naruto no longer stood in mid-air, but slowly flew over and stood on the Black Dragon Monarch's head.
[Main Quest "Black Dragon's Heart" Completed]
[Quest Rewards: New Dungeon "His Majesty the King's Request" Unlocked, 8000 Exchange Coupons Obtained, 60,000 Experience Points Obtained]
[Level Up!]
[Obtained 10 Free Attribute Points]
"Did my dominion over the Black Dragon Monarch, transforming it into a 'Shadow,' also count as fulfilling the summoning conditions?"
"I thought there would be more rewards—"
Naruto didn't hesitate, putting all 10 free attribute points into the [Spirit] attribute.
His [Strength] and [Constitution] attributes were already very high, so he continued to focus on increasing his [Spirit] attribute.
Especially since attributes like [Strength] and [Agility] could be boosted through skills like Madara's Mark, Lightning Release Chakra Mode, and Eight Inner Gates, the [Spirit] attribute, which couldn't be boosted in such ways, became particularly important.
After allocating his attributes, Naruto waved his hand, dismissing the attribute panel, and then began to consider the new dungeon—His Majesty the King's Request.
This Majesty the King, of course, referred to the King of the Human Kingdom.
"So the new quest is in the Royal Capital?"
"Looks like I need to go to the Royal Capital. It just so happens that I made a deal with the Crown Prince in the Wind Capital earlier, and he hasn't given me the transfer mirror yet."
Naruto's thoughts stirred. He took out the drifting bottle, put away the Ghost Ship suspended between the Red Moon and Green Moon, and then placed it in his [item bar].
Having just acquired a new mount, Naruto naturally wanted to enjoy it.
