'Fire Refusal!'
With his powerful sensory abilities, Hagoromo Otsutsuki sensed the movement behind him the instant he vanished.
Without hesitation, he launched an instant counterattack.
Almost in an instant.
Terrifying flames erupted from his body, like a sun exploding in an instant. Hagoromo Otsutsuki's high-pressure water stream was instantly vaporized, and even his clothes and hair began to catch fire; his skin even started to crack from dryness.
'Sage Art: Water Formation Wall!'
Forcing himself to endure the discomfort of his throat being scorched, his voice grew hoarse. After struggling to form four hand seals, a sky full of violent water currents swirled and converged, protecting him in the center to resist the disaster-like flames.
But, it was useless!
The violent water currents were instantly evaporated, buying him only two seconds of time.
'Sage Art: Dust Release: Detachment of the Primitive World Jutsu!'
Hagoromo Otsutsuki's hands began to glow, his speed far surpassing Ōnoki's. A massive transparent cube formed, instantly enveloping the sea of fire.
'Yomotsu Hirasaka!'
Uchiha Jin's eyes instantly turned into Rinnegan, and in the blink of an eye, he left the enveloped area.
The next second.
Within the range of the transparent cube, all matter began to be annihilated.
But what left Hagoromo Otsutsuki stunned and terrified was that the sea of flames was completely unaffected, leaving him utterly bewildered.
Why? He couldn't figure it out!
Logically, any Ninjutsu should have been annihilated by Dust Release, let alone the Sage Art-enhanced version he used.
"I'm done playing with you!"
"Let me see if you, an Ōtsutsuki, have mastered any ultimate-level Divine Arts."
"Hell of Heat, rise!"
Uchiha Jin's gaze was cold and indifferent.
His entire body was wrapped in violent flames. From the moment he started testing Hagoromo Otsutsuki until now, even though the opponent had been enhanced by Gamamaru's Sage Art, the techniques he used were all Tobirama's...
Hagoromo Otsutsuki hadn't used a single ability belonging to the Ōtsutsuki level yet.
At this moment, he wanted to test it!
If Hagoromo Otsutsuki hadn't even mastered Ōtsutsuki Divine Arts and could only use techniques created by strong individuals in the Ninja World, it would only prove that this person was a fool.
Lying dormant in the Ninja World for thousands of years was purely a waste of time.
For a fool like this, he might as well just die.
He plunged his Zanpakutō directly into the ground, and immediately, dozens of sky-piercing pillars of fire erupted. The flames filling the sky tore through the earth, began to converge, and instantly detonated completely.
In an instant, within a radius of thirty kilometers, the torn earth turned into magma. Looking around, the entire land had become scorched earth.
Especially the entire world; amidst this intense heat, even the void was burned until it distorted, and Hagoromo Otsutsuki himself began to burn.
The next second, Hagoromo Otsutsuki tried to tear through the void and use a portal to leave. But, he failed!
Although Uchiha Jin didn't use any Sealing Jutsu, the power of Ryūjin Jakka was too terrifying, having completely torn apart the entire space.
The space was extremely unstable, so Space-Time Ninjutsu naturally failed!
"Damn it, bastard!"
"It's clearly just ordinary Fire Release, why is the power so strong?"
"Even Dust Release has failed!"
"It can even distort and tear apart space; is this f*cking still Fire Release?"
Hagoromo Otsutsuki couldn't comprehend it.
Logically, Fire Release was the trashiest Ninjutsu, rarely even used by Ninjas, at most used to block the enemy's line of sight to create an opportunity for a sneak attack.
But why? Why could such trashy Fire Release, in the hands of the Uchiha Jin before him, erupt with such world-destroying power?
Following that, he condensed a dozen Truth-Seeking Orbs, attempting to directly annihilate the flames before him.
Logically, this was the strongest Yin-Yang Release, capable of nullifying all non-Sage Art Ninjutsu, but it was still ineffective against the bizarre Fire Release before him.
What should he do? A flash of panic appeared on Hagoromo Otsutsuki's face, because he could feel that in just a few dozen seconds, his physical body was already beginning to be unable to withstand it.
His entire body was being carbonized and collapsing from the scorching, and this situation was continuously worsening.
Although he had been using the creation and regeneration power of Yin-Yang Release, trying to repair his gradually collapsing body.
Unfortunately, it could only delay it!
The creation and regeneration power that could save a dying Might Guy in the original work, now facing Uchiha Jin's terrifying Fire Release, was estimated by Hagoromo Otsutsuki to last, at best, a few minutes.
'Indra's Arrow!'
The ultimate Lightning Release Ninjutsu of Sasuke in the original work, which required absorbing the Chakra of the Nine Tailed Beasts and using Susanoo as a medium for the arrow, was just casually used by Hagoromo Otsutsuki.
Almost in an instant, the massive arrow tore through the void, its speed reaching the limit, as it flew towards Uchiha Jin.
And, regarding this, Uchiha Jin's eyes remained terrifyingly indifferent.
'Yomotsu Hirasaka!'
He casually opened the lava dimension of Amenominaka, and after the huge Indra's Arrow was transferred inside, it exploded, splashing magma everywhere.
Hagoromo Otsutsuki was stunned for a moment: "You know Mother's technique?"
"Kaguya?" Uchiha Jin smiled and nodded: "Of course, I do!"
"Let me show you another one, All-Killing Ash Bone!"
In an instant, a gray cylinder, hidden by the flames, instantly struck Hagoromo Otsutsuki.
Almost in an instant, Hagoromo Otsutsuki's body began to turn gray-brown, and his entire physical body began to collapse.
"I really didn't expect to see Mother's technique again."
Hagoromo Otsutsuki murmured.
However, the next second, his entire body collapsed like a phantom, and then he perfectly resurrected in another location.
"Izanagi?"
Uchiha Jin's expression remained unchanged.
Regarding the Hagoromo Otsutsuki before him, he was actually quite annoyed.
It wasn't that the opponent was that powerful; after all, he had already died once, and he believed this was Hagoromo Otsutsuki's full strength.
To put it bluntly, this strength was very lackluster!
Even though he had been hiding in the Pure Land for so many years, seemingly collecting a very massive amount of Chakra, and had stolen countless techniques from strong individuals in the Ninja World...
But, it was useless!
Like those Ōtsutsuki in the original work, they all belonged to the category of pure stat monsters with lackluster combat prowess, but incredibly thick health bars.
It was very difficult to kill him in one hit; the only way was to keep grinding him down!
'All-Killing Ash Bone!'
Having figured this out, Uchiha Jin immediately changed his strategy.
While maintaining the Hell of Heat, using flames to scorch his physical body, and incidentally grinding away his soul bit by bit.
On the other hand! He used All-Killing Ash Bone like a machine gun, continuously firing and killing at Hagoromo Otsutsuki.
In the end, he still failed to pull off any flashy killing moves. After thirteen long deaths and resurrections, eventually, amidst his constant cursing and begging for mercy, his soul was completely ground away by the flames of the Hell of Heat.
He was dead!
And he died meaninglessly, which left Uchiha Jin quite disappointed.
Originally, he had hoped to probe the means of the Ōtsutsuki Clan from Hagoromo Otsutsuki, thereby gaining some experience for dealing with the Ōtsutsuki in the distant stars later on.
But, unfortunately.
Although Hagoromo Otsutsuki was an Ōtsutsuki, he was a native born in the Ninja World.
He hadn't learned the techniques of the Ōtsutsuki Clan from Kaguya, let alone things like the Karma or Divine Arts of the Ōtsutsuki Clan.
It was tedious and incredibly dull!
As for—Gamamaru?
This Great Toad Sage from Mount Myōboku clearly hadn't signed a conventional Summoning Jutsu contract with Hagoromo Otsutsuki, so he died the moment Hagoromo Otsutsuki died.
At the time, Uchiha Jin had wanted to save him, but unfortunately, this action had no significance.
The moment Hagoromo Otsutsuki died, his soul collapsed along with him.
