"Rise!"

I quickly raised the remains of the robots I defeated. They immediately returned back up to their feet, transformed into Undead Robots, they became bulkier and gained metallic scales, dragon tails, wings, and horns.

"Come with me!"

I rushed forward, catching up with Zero Three, who was fighting the Primordial Beasts and Zero Two. It seemed she was easily overwhelming them.

Meanwhile, Zero One was fighting against a couple of the same machines I just battled while trying to continue hacking the internal synapsis of the Mechanical Tree by connecting to it through the floor, which she smashed with her fists.

"Go help Zero One!"

They rushed towards her, battling the robots that were trying to interrupt her. They unleashed blazing dragon breath, used their dragon claws to slash through their foes, and used their herculean strength to overwhelm them physically.

It could be said my undead were most of the time stronger than their former, living selves! The only drawback was that they only lasted some time before going back to being junk or corpses.

But that didn't matter right now, in the heat of the moment!

CLASH! CLASH! CLASH!

"Hah, for being my older sister, you sure are weak. Get out of my way."

Zero Three clashed against Zero Two, easily overwhelming her with her massive katanas, which unleashed a storm of slashing waves of golden and white light.

SLASH! SLASH! SLASH! SLASH! SLASH!

"Nnnggh…! Nngaaarrgh!"

Zero Two couldn't keep up with her gigantic attacks with her own swords; even if she could keep regenerating them or her own armor, she was pushed away, with her left arm visible, armed as it was torn apart.

BAAAM!

She rolled over the ground, vomiting sparks of electricity coming from her wounds, as her swarm of nanomachines rapidly started regenerating her wounds.

"It seems the newer the model, the more superior it is," Zero Three said. "I am simply the optimized version. With the Immortal Machine Warrior MK-1, I am invincible!"

Using her wings, she unleashed a blast of lightning and reached Zero One in an instant, swinging her katanas against her to slash her into two halves.

At the same time, I turned into lightning once more, partially using my [Divine Thunder God Body: Raijin's Embodiment] Skill, but only for a couple of seconds.

This was a technique I figured out was much better than using it at full time, abusing its ability to give me an explosive burst of speed once activated.

FLAAASH!

Within a split second, I reached Zero Three, hitting her as I materialized a gigantic fist made of rainbow Ki, fusing the power of Hope with the Cursed Seals, activating them across my body.

"{Myriad Self Arts}: {Heaven-Collapsing Fist}"

BOOOMMM!!!

An explosion of converging energies erupted, blowing away the massive mecha way before they could lay a finger on Zero One.

"Phew, that took a bit out of me," I sighed in relief. "Zero One, you ok?"

"I-I am!" she said desperately. "I'm trying my best here…! But it is so riddled with firewalls! It's so hard to get through! She really prepared for this!"

"Is there a way I can help?" I asked.

"Bring Zero Two here! She can help me out!" she said.

"Gotcha." I nodded.

FLASH!

I quickly transformed into my Raijin form once more, rushing towards Zero Two, grabbing her, and then placing her right next to her sister.

The genuine version of this novel can be found on another site. Support the author by reading it there.

"Don't go fighting recklessly! Help Zero One! I'll keep Zero Three busy!" I said.

"D-Dammit!" Zero Two really wanted to fight instead. "Fine! What do I do?!"

"Help me amplify the signal I expand across the network!" said Zero One. "Here, hold my hand."

As they held hands, their powerful Auras converged, giving Zero One's ability to implant new data into an already existing digital mind more power.

"W-We can do this!"

"Uugh! T-This is damn hard!"

As I left them doing that, I had no time to lose; only a couple of seconds had passed since I punched Zero Three, but she was already rushing towards us at lightning speed.

She swung her two katanas at her sisters again, making them resemble deadly guillotines!

However…

CLAAASH!

I appeared before her, turning into lightning itself; there was little I couldn't catch up to! Using Gram, Qin, Heracles Axe-Sword, and the Divine Celestial Sword: Oblivion I had obtained from Solomon back then, which I could now finally wield.

Using all four of these powerful swords, further boosted with everything else within me, the concert in the background, and my Cursed Seals activating one after another, as I embodied Pain within my mind and released it…

BOOOM! BOOOM! BOOOM! BOOOM!

A barrage of colorful explosions engulfed Zero Three, as she was unable to realize what even hit her until she glanced above me, noticing a giant, slender man made of shadows, wielding a huge sword.

Made out of my own Demonic Ki Aura, this was the embodiment of my brother's Pain in the future, the novel I read that showed his lonely path.

I was slowly beginning to figure out ways to use it better!

"W-What is that?!" Zero Three asked. "Such nonsensical power…!"

"There's no nonsense in my technique, Zero Three," I said. "If anything, the only nonsensical thing is the cruelty of the universe. And the pain it endlessly brings to us all."

"P-Pain?!"

"Yes, pain."

I rushed forward, clashing against her. She desperately swung her two katanas, while her secondary pair of arms suddenly took out large cannons, firing beams of light.

I had to evade, intercept, or parry her giant katana attacks all while blocking the beam attacks with my dragon shield!

CLASH! BOOM! CLASH! BOOM!

"You truly believe you can keep up with me?"

Zero Three seemed confident, as she suddenly released an even stronger Immortal Aura from her mech, whose secondary pair of arms dropped the two giant cannons and began making hand signals.

Wait, those hand signals… Is it conjuring a formation?!

FLAAASH!

"Too late."

A formation manifested below me, as I was left slightly speechless. A machine was creating an immortal ki formation!

"{Heavenly Machine Formation Arts}: {Nine Heavenly Seals}"

Out of nowhere, mechanical chains emerged from the formation, wrapping around my entire body. Each one was of a different color, from red, green, blue, black, yellow, purple, and so on, embodying the Nine Heavens! I felt restricted, as I sensed my own strength rapidly weakening.

Ding!

[You have been trapped inside the {Heavenly Machine Formation Arts}: {Nine Heavenly Seals} chains! As long as you're within the range of the formation or touching its chains, All Stats -50%, Skill Power -40%, and Magic Spell Power -30%.]

[The Nine Heavenly Seals bestow Heavenly Restrictions upon your body!]

[Your Physique Abilities are being blocked!]

[Your Martial Core Abilities are being blocked!]

[Your Spiritual Body Abilities are being blocked!]

[Most of your Ki is being sealed!]

"I designed this specifically for you!" Zero Three said. "Now perish!"

As I was restrained by the chains, she swung her katanas at me, gigantic in size, capable of cleaving through it all; I would easily have a quick death if they were to slice through me.

SLAAASH! SLAAASH!

Yet!

"Sepa! Bastet!"

CLAAASH!

"Nnggh?!"

Zero Three groaned in annoyance, noticing her two katanas were blocked by a cosmic pressure emerging from my body.

Sepa and Bastet emerged as powerful Egos themselves, embodying their strongest divine forms, and not just small silhouettes made of rainbow ki.

Now that they had further merged with my Soul and my Cosmic Core, they could manifest at a much stronger, greater level.

This, coupled with the concert's buffs, made them much mightier!

"Don't get ahead of yourself, little robot," said Bastet, smiling. "Should we teach you a lesson, hm?"

"Anna! Don't be too reckless!" said Sepa.

"Thanks for the save!" I said, sighing in relief.

"Reports had said you possessed strange powers, among them, summoning beings," said Zero Three. "But this is beyond strange! What sort of energy is this?!"

Zero Three was growing desperate; instead of her calm demeanor, she was constantly growing more and more furious. With her two giant blades, she unleashed a barrage of attacks, creating a storm of cutting slashes everywhere.

"No matter. As long as you're trapped inside my formation, you'll have to simply succumb to your fate either way."

SLASH! SLASH! SLASH! SLASH! SLASH!

Although my body was wrapped in chains, I quickly moved my weapons, unleashing a defensive technique using Thousand Blades and Myriad Self Arts combined with my Hope Arts.

"{Myriad Self Arts}: {Heavenly Fortress Stance}"

Dozens of Egos Specters merged into my Aura, amassing it with Hope Essence, ending up transforming into a massive golden fortress around me.

Each time an attack reached me, the fortress activated, making my own body move automatically, even making me move beyond my normal physical limitations!

The result?

CLASH! CLASH! CLASH! CLASH! CLASH!

"I-Impossible!"

I was able to parry all her attacks, sending shockwaves of my own Ki Aura against her as countless explosions started bombarding her constantly.

At the same time, Bastet and Sepa moved forward. Sepa transformed, continuously becoming larger and larger, something she could never do before our new contract.

"This is my true self! Can you handle it, little robot?!"

She roared ferociously, clashing against Zero Three with her giant mandibles as Zero Three intercepted her with her fists and her katanas, explosions of Ki and Cosmic Light erupting.

At the same time, Bastet smiled at me, quickly summoning a golden staff with a red mirror on top of it.

"This is merely an imitation, but let me show you my true power… I somewhat feel stronger now, thanks to our new contract," she giggled.

"{Ra's Sunlight Mirror}"

As Sepa and Zero Three clashed, while Sepa was slowly being pushed back, suddenly, a giant red beam of pure sunlight reached the giant mech's chest!

BOOOMMM!!!
