"Whoosh—"
Under the painfully strained gaze of the casino owner,
Ren and Tsunade exchanged their mountain of game tokens for cash and left the casino loaded with winnings.
No one foolish enough came to provoke them.
Not long after leaving, they used the Flying Thunder God Technique to return directly to the inn.
"I'll take Karin out for some field practice…"
Having just lost what should have been a guaranteed win, Tsunade looked completely deflated.
"You can do whatever you want, but don't go overboard."
Over the past two years, Ren had trained his taijutsu by repeatedly fighting two Wood Clones of himself.
He often ended up covered in injuries.
Tsunade remembered it vividly, so she reminded him again.
"No need to worry. I won't do something that stupid again."
Ren shrugged.
"After all, whether it's taijutsu or ninjutsu, Wood Clones can't really pressure me anymore."
Watching Tsunade leave,
Ren returned to his room.
He glanced at the Wood Clone he had left behind earlier.
Although it was only a substitute body, Ren hadn't let it sit idle.
Instead, it had been studying secret technique documents from clans like Ino–Shika–Cho.
Ren didn't recall it yet.
His black eyes turned crimson—
revealing the Eternal Mangekyō Sharingan.
"Netherworld Space—open!"
Ren directly activated Ōanamuchi.
His body vanished instantly.
Within a 500-meter radius,
streets, buildings, residents, and pedestrians—
all appeared before him as translucent three-dimensional projections.
Now that his ocular power had grown through training,
the Netherworld Space created by Ōanamuchi had become even more concealed.
Ordinary Byakugan or Sharingan users couldn't detect it.
Even Karin's extremely sensitive Kagura Mind's Eye couldn't sense Ren while he was inside.
Moreover—
its range had expanded dramatically.
From the original 200-meter radius…
to nearly 500 meters.
For most combat situations,
that was already more than enough.
"Whoosh—"
The intricate patterns in Ren's eyes spun rapidly.
A vast amount of chakra surged from his body.
"Crack… crack…"
Massive skeletal chakra structures formed.
A giant half-body skeleton appeared.
It was entirely azure blue, towering around him.
But it didn't stop there.
"Whoosh… whoosh…"
Countless chakra strands emerged,
forming muscles, tendons, and tissues.
A layer of chakra armor appeared.
The half-body giant grew even more imposing.
Then—
Ren, protected inside the massive construct, floated into the air.
More chakra materialized.
The giant's lower body began forming.
"Boom—!"
The ground of the Netherworld Space trembled.
A gigantic azure warrior stood upright.
Its height exceeded thirty to forty meters.
Just looking at it inspired fear.
If Uchiha Itachi were present,
he would probably be too shocked to speak.
Because this—
was Susanoo.
Normally, only those who possessed a complete pair of Mangekyō Sharingan could wield this "power of the gods."
Yet Ren used it effortlessly.
And unlike the incomplete half-body forms of most Uchiha—
his had already manifested a complete giant form.
Even more incredible—
he showed no strain at all.
"The fourth form of Susanoo… acceptable."
Inside the azure giant,
Ren crossed his arms calmly.
Then he raised his right hand.
A massive chakra sword, shaped like a katana, formed.
It looked incredibly sharp.
The giant grasped it.
"Slash!"
In the next instant—
the azure Susanoo swung the blade downward.
"Whoosh—!"
A gigantic azure sword aura burst forth.
It cleaved through the ground in front of him.
"BOOM!"
The earth shook violently.
When the dust cleared—
a horrifying trench stretched across the land.
The cut was smooth.
Deep like an abyss.
It extended all the way to the edge of the Netherworld Space.
Anyone seeing it would break into cold sweat.
"The Ame-no-Murakumo Sword, also known as the Great Mass Sword…"
Ren murmured.
"A divine blade said to split mountains and seas with a single swing."
"The power is… decent."
He smiled slightly.
"But what truly satisfies me…"
"Is the other artifact that comes with my Susanoo."
On the giant's left hand,
a radiant crystal-like gemstone formed.
It shimmered with mysterious light.
Yes.
Just like other Uchiha who awakened Susanoo,
Ren's Susanoo possessed exclusive divine artifacts.
First Artifact:
Ame-no-Murakumo Sword (Great Mass Sword)
A supreme blade capable of cleaving mountains and seas.
Unstoppable and indestructible.
Second Artifact:
Chibiki Stone
A legendary object said to be indestructible.
It could even block Yomotsu Hirasaka, preventing dimensional travel.
Not even space-time ninjutsu could bypass it.
It possessed the ability to interfere with space-time itself.
It could freely grow or shrink.
It could be used for both defense and offense.
More importantly—
the Chibiki Stone could perfectly fuse with Susanoo.
"Once Chibiki Stone merges with Susanoo," Ren said,
"its defense becomes unimaginably powerful."
"It becomes nearly indestructible."
"And because it interferes with space-time…"
"Even techniques like Kamui would fail to affect it."
Ren raised two fingers in front of him.
The radiant gemstone floated upward.
"Whoosh—"
It dissolved into brilliant light—
and merged into the fourth-stage Susanoo.
The entire azure giant now glowed with dazzling radiance.
"Wood Release — Wood Dragon Technique!"
Ren's eyes sharpened.
"ROAR!"
The ground trembled.
A gigantic Wood Dragon burst from the earth.
It grew rapidly.
Its massive body dwarfed even Ren's Susanoo.
It roared ferociously.
"ROAR—!"
Under Ren's command,
the dragon lunged toward him like lightning.
Yet—
the Susanoo didn't use the divine sword.
Instead—
its left hand clenched into a fist.
The enormous fist glowed with brilliant light.
It smashed forward with overwhelming force.
"BOOM!!!"
The impact shook the world.
The Wood Dragon cried out.
Its massive body was blasted backward like a cannonball.
Its head shattered into splinters.
Wood fragments scattered everywhere.
Meanwhile—
the azure Susanoo stood there.
Completely unharmed.
It was almost unbelievable.
The Wood Dragon—
a technique once used by the First Hokage to restrain tailed beasts—
had been destroyed with a single punch.
Normally,
a fourth-stage Susanoo couldn't easily overpower Wood Dragon.
But this Susanoo had fused with the Chibiki Stone.
Its defense had been strengthened to a terrifying degree.
And that overwhelming durability—
also translated into incredible offensive power.
Truly monstrous.
