Reborn in Naruto As Madara's Grandson

Bam…

Hiruzen slams the Adamantine Staff on the barrier. The barrier shakes a little from the force of the attack.

Swoosh…

The recoil force of the barrier pushes him back.

Argh…

The Adamantine Staff transform back into Monkey King Enma. He grimaces in pain and rubs his fur.

"This barrier is very powerful. It is almost impossible to break it from outside unless you apply enough force to overcome the repulsive force of the sealing formula."

Enma remarks. It is an advanced version of 'Summoning: Quintuple Rashomon' used by First Hokage Hashirama Senju. Hiruzen the enemy is quite powerful this time around.

Hiruzen nods to Enma and remarks.

"That Uchiha boy, I told you about is inside the barrier. I hope he will be able to search for a way to deal with this barrier."

"So, that's how it is. Then I will be going, Hiruzen. You should also take care of your old bones." Enma disappears in a poof of white smoke.

"Humm…" Hiruzen nods and stares at the barrier.

"I hope everything will turn fine. Konoha has already weakened a lot in this past decade."

-------------------

Inside the barrier,

Izuna stares at the barrier. He raises his eyebrows as he inspects the barrier.

"This is quite a high level, Fuinjutsu Barrier. If I remember correctly, it is the advanced version of 'Summoning: Quintuple Rashomon'.

It requires a large amount of chakra to cast this barrier. It has a formidable defense that can equally distribute the force of an attack around the entire barrier."

Izuna activates his Sharingan and studies the barrier. He scans multiple Fuinjutsu seals on the Rashomon Gates.

"The barrier has two defense layers. The first defense layer is the Green energy barrier and the second layer is the Dark Iron Demonic Rashomon Gates. Unless you destroy the inner Rashomon gates, the barrier will continuously regenerate the outer energy layer by sucking the chakra and the life force of the trapped people.

This makes this barrier self-sustaining. That means, there is no need for the caster to maintain the barrier, quite a sinister barrier indeed. But it has a fatal weakness, if it concentrates the force of the attack at a point, then I can destroy the Rashomon Gates before they regenerate."

Izuna concludes the weakness of the barrier.

'I can destroy this barrier in two hits if I go full power. Otherwise, it will take 5 or 6 hits to destroy this barrier.'

Izuna turns towards the masked man.

'But I guess he won't give me the time. Let's deal with him first.'

Swoosh…

Izuna appears besides Akira and Aiko. He confronts the masked man.

"Mom and Dad, leave him to me. I will deal with him."

Akira retreats. Aiko hesitates for a while, but she retreats nonetheless.

"Izuna dear! He is very strong. Take care while fighting him." She warns him.

"I will keep that in mind." Izuna nods to Aiko and turns towards the masked man.

The masked man releases his hands and makes some more hand signs.

"Who are you?" Izuna questions him.

"Wind Release: Extreme Wind Bullet Barrage"

The masked man sucks an extensive amount of air and fires multiple wind bullets at Izuna. Izuna twists his body in the air and easily dodges the bullets.

The wind bullets punch multiple holes through nearby houses and blow them away.

'The power of this B-rank jutsu is enhanced to an A-rank jutsu. I have never met with such a strong wind user before. Who is he exactly?'

Izuna frowns.

"Lightning Release: Kaminari's wraith"

The masked man fires multiple concentrated bolts of lightning at Izuna. The bolts travel extremely fast towards Izuna and surround him.

Crackle… crackle…

The ground cracks from the lightning blast. Izuna raises his right hand and coats it in the wind chakra.

"Dark Release: Chakra Absorption"

Two dark red overlapping Diamond marks appear on his right palm. Izuna absorbs the lightning jutsu through the mark.

He directs the palm towards the masked-man.

"Dark Release: Judgement"

He fires the lightning jutsu back towards the masked man.

Tch…

The masked man clicks his tongue and makes some more hand signs.

"Fuinjutsu: Kama Barrier"

A green barrier appears in front of him and blocks the lightning bolt. He immediately jumps back and avoids the attack from Izuna.

Boom…

An enormous crater appears at the previous position of the masked man. A spiraling thunderstorm engulfs the entire crater. The thunderstorm calms down after a while, and purple lightning flickers through the crater.

'He dodged my Vanishing Purple Lightning Rasengan.' Izuna warily glances at the masked man.

"Izuna Uchiha! Today will be your last day. After I kill you, I will kill your entire family and send them to the afterlife with you."

A raspy voice greets Izuna.

"Let's see, if you have the power to make that possible."

'Swift Release: Sonic Steps'

Izuna disappears and immediately appears in front of the masked man.

He clenches his fist and infuses a large amount of chakra in them.

"Power Release: Destruction Fist"

His fist glows with an orange color and smashes into the masked man.

Bam…

The punch pushes the masked man a little. The masked man regains his balance and delivers a punch of his own.

The masked man's fist glows with white light.

Bam…

Izuna crosses his arms in front of his chest.

'Metal Release: Adamantine Skin'

He blocks the punch, but the force flung him away. Izuna somersaults in the air and regains his balance.

He quickly makes some hand signs and concentrates a large amount of chakra in his palms.

"Radiation Release: Nuclear Devastation"

He fires a condensed green orb of chakra towards the masked man. The orb quickly closes on the masked man.

"Release"

Izuna claps his hand. The orb expands immediately and detonates on top of the masked man.

"This can be a little bad."

The masked man forms a multi-layered green barrier to protect himself.

Boom…

An enormous explosion engulfs him. The explosion rises into a large pillar of green light and slowly vanishes into the air. A massive gap appears on top of the barrier.

---------------

Outside the barrier,

Hiruzen and the rest of the elders stare at the explosion with wide-eyes.

A gigantic ripple travels across the 'Sensing Sphere' and the water of the sphere boils.

Sweat glides down the forehead of the 'Senser Corp' members. They immediately infuse chakra in the sphere to stabilize the barrier.

The barrier stabilizes and stops boiling, but the ripples continue to fluctuate on the barrier. The Leader of the Corp wipe his forehead and report to Hiruzen.

"Hokage-sama, this explosion is very potent. It has enough power to obliterate one-third of Konoha." The Leader gulps his saliva as he imagines the effect of jutsu on the village.

Hiruzen continues to stare at the explosion as he mutters,

"What kind of fight is happening inside the barrier? Such powerful ninjutsu. It is at the level of a 'Forbidden Technique'."

"Quickly the earlier explosion opened a hole in the barrier. We have to immediately breach the barrier and inspect the situation inside the barrier." One of the Dragon Unit members notices the large hole in the green barrier.

Multiple Anbus jumps towards the hole and tries to enter inside the barrier.

Swoo…

The demonic eyes on the gates lit up. They immediately fire a green beam at the breach. The barrier starts to repair itself.

"Quick! Enter inside before it repairs."

The Anbu members increase their speed.

Fwoosh…

The barrier closes and many Anbu members slams into the barrier.

Aaah…

Their body catches fire and turns into ashes. The rest of the Anbu member stops their track and jumps back.

"The regeneration rate of this barrier is ridiculous. It requires a large amount of chakra to sustain this barrier?"

The Leader of the 'Barrier Corp' scrutinizes the barrier.

"Oh! You are finally here, Kakoi. Can you find a weakness of this barrier?"

Hiruzen greets the newcomer.

The newcomer wears a 'Shinto' priest robe. He has shoulder-length brown hair and unique marking under his eyes. He wears a pointed hat with the 'Barrier Team' symbol above his forehead protector. Kakoi bows before Hiruzen.

"I will try my best, Hokage-sama."

"Good!" Hiruzen nods to Kakoi and turns towards the barrier.

Kakoi instructs other members of the 'Barrier Team' to aid the 'Sensor Corp'.

---------------

Inside the Barrier,

The dust and debris from the explosion settle down. The masked man walks out of the crater. His body has scorch marks and there are multiple third-degree burns on his body.

The blast destroys the green barriers around his body. Parts of the barrier flickers for a while before they dissipate.

There is a strange purple symbol on the masked man's chest.

The masked man makes some strange hand signs and taps the symbol on his chest.

A white glow coats the masked man's body. His wounds and burns regenerate quickly. The white glow heals the wounds at a rapid rate.

Izuna activates his Mangekyo Sharingan and closely inspect the white glow.

"This is… this is Light Chakra. But how?"

Izuna's eye widens in surprise.
