Seeing this, Renya's pupils suddenly contracted, and he instinctively tried to continue retreating.
But a powerful suction force struck instantly, pulling him uncontrollably toward Uchiha Madara.
"Damn it!"
Watching Madara's palm draw closer and closer, Renya could only use the Flying Thunder God Technique to appear beside Tobi.
He had long since marked Tobi with a Flying Thunder God seal, using it to break free from the terrifying suction of Shinra Tensei.
If not for that, he would probably have already been dragged over by Madara.
"Flying Thunder God Technique."
Uchiha Madara murmured softly.
That troublesome ninjutsu invented by Senju Tobirama—back then, his younger brother Izuna had been severely wounded by this very attack.
In the end, he died from his injuries.
"Before absolute power, how long can these little tricks really last?"
Uchiha Madara looked at Renya, his face filled with unrivaled confidence.
Renya's strength could indeed be called impressive, but compared to him, there was still a gap.
As he spoke, he rushed toward Renya at extreme speed.
The underground space was filled with dust.
Renya's figure appeared like a phantom at Madara's left side, his tachi thrusting straight toward Madara's left ribs at lightning speed.
Uchiha Madara swiftly twisted his body to evade, the blade passing across his front by a hair's breadth.
Renya did not retract his blade. With a twist of his wrist, the thrust turned into a slash, the blade-light sweeping horizontally!
Uchiha Madara calmly leaned back, the blade grazing past the tip of his nose. The gust it generated stirred the white hair on his forehead.
"Shinra Tensei!"
Just as Renya was about to continue his attack, he was blasted away by the immense repulsive force of Shinra Tensei. He adjusted his posture midair, flipped backward using the recoil, and formed seals with one hand.
"Fire Release: Great Dragon Flame Technique!"
Three ferocious fire dragons roared out of his mouth, lunging toward Uchiha Madara from different angles.
Seeing this, Uchiha Madara rapidly formed seals with both hands.
"Fire Release: Great Fire Annihilation!"
What burst from his mouth was a vast sea of flames, instantly swallowing Renya's three fire dragons.
After devouring them, its momentum did not diminish, and it continued surging toward Renya.
The scorching heat distorted the air. The rock walls were baked red-hot, radiating rolling waves of heat.
Renya's figure vanished in an instant, using the Flying Thunder God Technique to appear at the far end of the underground space.
During the earlier exchange, he had already scattered specially made Flying Thunder God kunai throughout the underground space, using them to maneuver and drag the fight.
"Space-time ninjutsu really is troublesome."
Uchiha Madara's calm voice came from behind him!
Renya immediately turned around, only to find that Madara had appeared behind him at some point.
So fast!
"Fire Release: Great Fireball Technique!"
The instant he turned, his left hand completed the seals, and a massive fireball blasted out of his mouth.
Uchiha Madara neither dodged nor evaded, simply raising his right hand.
"Blocking Technique Absorption Seal!"
An ability unique to the Preta Path, capable of absorbing an opponent's chakra and ninjutsu and converting it into one's own power.
In battle, it could be used for both defense and replenishing chakra.
An invisible barrier appeared before him. When the enormous fireball struck it, not even the slightest ripple formed before it was completely absorbed.
"Your ninjutsu is useless against me."
Uchiha Madara stared at Renya expressionlessly, his words brimming with absolute confidence.
Before these Rinnegan, any attack was futile.
A trace of resolve flashed through Renya's eyes. He knew that without using his full strength, victory would be impossible.
He fully activated the ocular power of his Mangekyō Sharingan. A dark crimson Susanoo skeleton slowly took shape.
As his ocular power poured in endlessly, flesh began to condense over the skeletal frame, eventually forming a half-body Susanoo.
"Oh? You've grown?"
At last, a faint glimmer of interest flickered in Uchiha Madara's eyes.
But only a glimmer.
For someone who could activate a complete Susanoo, this kind of half-finished Susanoo posed no threat.
Having never fought another Susanoo before, it sparked a bit of combat interest in him.
"Let me show you what true Susanoo really is!"
Blue chakra began to surface around Uchiha Madara as his own Susanoo started to take form.
Very soon, a blue half-body Susanoo, roughly the same size as Renya's, appeared.
In the underground space, two half-body giants stood proudly.
One red, one blue.
Every collision between them made the rock walls tremble violently.
The dark crimson longblade roared through the air as it slammed viciously toward the blue Susanoo's head.
Uchiha Madara stood within the blue half-body Susanoo, his Rinnegan utterly calm.
Facing this ferocious blow, the blue Susanoo neither dodged nor evaded, instead meeting it head-on with a punch!
Boom!!!
At the instant blade and fist collided, a terrifying shockwave exploded outward in a circular burst.
The underground space could not withstand such power. Massive chunks of rock continuously fell from above, directly burying both Susanoo beneath them.
...
But soon, they burst free from the rubble, leaving the collapsed underground space behind and shifting the battlefield to the surface.
"You've managed to fight me for this long. You have every right to be proud."
Uchiha Madara crossed his arms over his chest and said in a deep voice.
"But the game ends here!"
Looking at Renya's unwilling expression, an inscrutable emotion flashed through Madara's Rinnegan.
Perhaps boredom—or perhaps something else entirely.
He had no intention of continuing to fight this brat.
Renya was no match for him. Continuing the battle held no meaning.
Better to end it here…
The blue Susanoo around him slowly dissipated, turning into countless specks of glowing chakra.
"Your pointless struggle ends now."
Uchiha Madara's voice was calm, yet carried unquestionable authority.
"Go crawl back to your Konoha."
Renya looked at Uchiha Madara unwillingly. The Rinnegan were simply far too overwhelming.
His Mangekyō Sharingan offered no advantage at all…
Moreover, Madara, having awakened the Rinnegan, could still use Mangekyō Sharingan abilities.
Only now did he truly understand the despair the Five Kage felt when facing Uchiha Madara.
"Go tell those people clinging to false peace to wait… wait for the day I, Uchiha Madara, bring true peace to the ninja world!"
Uchiha Madara stared straight at Renya, his Rinnegan emitting a dim purple glow.
"Believe me, that day won't be far off."
"Madara-sama, you don't need to force yourself anymore. Your body has already reached its limit, hasn't it?"
Renya did not retreat after these words. Instead, he smiled as he looked at Uchiha Madara, as if he had discovered the truth.
Although seventy-year-old Madara was still powerful, his physical condition was long past its peak.
To have fought him for so long could already be called remarkable for his age.
"Are you looking for death?"
Uchiha Madara narrowed his eyes slightly, a thick killing intent radiating outward.
