The Protagonist's Sister Is Actually The Strongest

Barely managing to escape with Song before the entire golden pagoda, perhaps the strongest Heavenly Construct of the Heavenly Empress was overtaken by the Demon King Seed, we were able to see the beautiful house quickly crumble apart and then restructure itself into a mechanical abomination.

I knew it! There was something like this hidden somewhere… So this means that not only was Song going to become the Demon King out of nowhere, all by the tricks of these damn constellations, but the trial was not over yet until we either stopped this or…

We killed Song as a Demon King.

Did that happen in the real story? Was that what the two of them had to go through? And if this is a different future, then it was in an even worse situation, while the world was already being invaded.

These damn constellations, even if this is a simulation, if they did this in real life, then it’s fucking horrible!

Now I feel like killing them the same way I slaughtered that snake of Uroboros.

“EXTERMINATE. DESTROY. ELIMINATE.”

As the giant made of gold and countless mechanical tentacles started moving across the skies, releasing a powerful aura of cosmic energy, electromagnetic energies, and divine ki, I saw a notification.

[You have successfully stopped the birth of the {Fifth Demon King, The Weapon of Destruction}!]

[However, the Demon King Seed has taken over a temporary yet unstable vessel, fusing its powers with it to come an Incomplete and Unstable Demon King.]

[The Incomplete and Unstable Demon King is constantly expanding and, at the same time, frying its own internal circuits until it becomes nothing but an endless mass of swirling mechanical parts.]

[If it were not stopped, it would overtake the entire world and transform everything into a mechanical nightmare.]

“THIS WORLD… IT SHALL FACE ITS END…”

A similar notification to when I stopped Heisenberg from becoming a full Demon King! However, incomplete Demon Kings are still tremendously strong.

And this one is without a doubt as strong as those.

Yet…

FLUOSH!

Suddenly, a gigantic portal of blue color opened within the titanic machine’s chest, breaking the boundaries of space and time.

Don’t tell me…

[The Incomplete Demon King has activated their Privilege: [Machine World Gate (SS Rank Privilege)], bringing forth a near endless army of Machines from their original world!]

It did the same as Heisenberg?!

No way!

The machines we thought we defeated just recently; they’re all coming back again?!

RUMBLE!

The skies above rumbled and trembled as countless machines started pouring out of the portal within the Demon King’s body endlessly.

They all flew with mechanical wings or propulsors—thousands of them within mere seconds! One group immediately rushed to attack us, hundreds at once.

The other groups split apart into several swarms, trying to get to the floating islands and also the world below!

“They’re trying to split into many swarms, so we won’t be able to catch them all!”

They learned from their previous battle, and in just a couple of hours, they came back even smarter and in even more numbers than before.

Perhaps the time dilation in their world is much faster than this, so for them, maybe months or even years passed while in here it was mere hours.

There’s barely a couple of hours before the trial ends too! This is too hard!

Is this what would have happened if the orthodox and the demonic factions unified under the same flag?

Even now, destruction comes.

“So many metallic monsters…!” Song cried; he was very afraid. “Buaaahhh! Why is this happening? Annaaaa! Where’s mama and papa?”

Song is the victim of everything that happened here. This poor child would have become that monstrosity if we had not stopped him from eating that seed.

Yet, I can’t help but think that, if we weren’t there in the real scenario, then… this boy truly became a Demon King.

Part machine, and perhaps part flesh…

At such a young age…

What a horrible fate he had!

All of this because he felt neglected and alone and wanted to explore the outside world.

The overprotectiveness of her parents ended up being what caused his terrible fate.

Because he wanted to be with his parents so much and because he lacked common sense from knowing and learning of the world and its dangers, the boy ended taking the offer.

They pretended to be nice, those cold machines; they know how to act and convince a small, innocent child.

Heartless pieces of junk!

“Don’t worry… Everything will be okay,” I said, looking at his adorable eyes as he cried. “Your big sister Anna is here to protect you! Mama and Papa are coming; I can sense their presences arriving. We have to just buy time for a couple of seconds! We have to stop the machines from going down; ignore the demon king; he’s too far away for us to be affected! Zero One, can I count on you?!”

“Yes!” she nodded.

“Okay! {Familiar Summon}!”

FLASH! FLASH! FLASH! FLASH! FLASH!

I summoned all my Familiars, who were in the palace, right by my side. Violet, Snow, Shiro, Fang Shuan, and… huh?

“W-What’s going on?! I was… training in my apartment and… Huh?! Anna?”

Wait, is that Sara?!

No way did that… The Familiar Summon just summoned her inside of this class trial!

There are no errors or notifications saying it’s wrong, so...

I guess it’s fine?

No, wait, it’s not fine!

This privilege is much more powerful than I imagined if it has the ability to summon people from a whole other world here.

Right inside a trial, which is located inside the Heavenly Empress Inner Realm!

“What are those machine monsters?! What’s going on? Is this a dungeon? No wait! And those people? A girl, and… is that a bird?”

“Who is she?!” Zero One wondered.

“N-No time to explain! A friend, Zero One!” I said. “Sara! Sorry, I didn’t intend to summon you here! But it seems you are indeed my Familiar now, dammit… I’ll explain to you what happened later! Can you please help me out fight these machines?”

“Ah, yeah!” She luckily brought her daggers with her and most of her equipment; apparently she was training in her apartment when I ended summoning her. “Okay, fine! Not like I got another option, fuck!”

“Thank you so much, Sara! I’ll explain everything once we’re done! I promise! And I’ll make sure to repay you for your help! I’ll even pay you with money or any item or whatever you want!” I said.

“Money would be fine, some items too… Well, whatever! Ugh, there are so many!” she groaned. “I guess it’s time to show off my training so far! {Shadow Spectral Rampage}!”

FLUOSH!

Her entire body turned spectral and then encompassed by shadows; she was an Undead now, of the spectral, ghostly kind. Sara gained many new abilities and powers after I resurrected her, and after the remaining death energy of Hel was left within her body.

SLASH! SLASH! SLASH! SLASH!

Like a storm of shadows and ghostly energies, she tore through hundreds of machines within seconds, tearing the spider-like and ant-like machines into pieces of junk flying everywhere.

“Woah, she’s strong!” Zero One was amazed.

“She’ll cover that area in the front!” I said. “Violet, Snow, Shiro, you make a team on your own and go stop the machines to the west over there! Meanwhile, Fang Shuan, you can take on the machines above us.”

“KRIEEEH!”

“AWOOO!”

“Kyuuh!”

“Sure thing! Leave this to me!”

The other four Familiars quickly rushed towards the battlefield in the middle of the skies. Having grown so strong after cultivating Ki for a while, everyone was much stronger despite level caps.

Violet, Snow, and Shiro had particularly obtained many new abilities and skills through all their training, and they had received the delicious enhancing snacks of the heavenly empress, so they were even stronger than before.

Meanwhile, Fang Shuan was… well, Fang Shuan, he turned giant like Violet and battled hundreds of machines on his own. I noticed Sara gasping as he saw the titan made of gold; she had not met Fang Shuan yet.

“Big sis Anna, the metallic bugs are going down!” Song alerted me.

“I got this!” I nodded, using my Ki Aura, and fusing it with my many other Auras, rapidly materializing my specialized combination Aura created from many abilities, skills, and the powers exerted from my equipment.

“{Myriad Self Arts}: {One Hundred Hands Aura}”

One hundred hands of rainbow energy wrapped around Song, tightly attaching him to my back. I can’t leave him in the middle of the sky; he’ll get torn to shreds. And I can’t just fly to the islands and bring him to his mother and father; there’s no time.

The only way is to bring him with me as I exterminate the machines moving towards the continent of Pangea!

“Wooaah! W-What’s this technique, big sis?!” He wondered; he stopped weeping due to the bright colors, making him very curious.

“My technique is called Myriad Self Arts!” I said. “Still in development; now hold tight; we’re moving down!”

FLASH!

With a single kick into the skies and by hyper charging my entire body with electricity and ki, I rushed down at lightning speed. Just as I expected, even when I turned myself into lightning momentarily, Song was not affected or electrocuted thanks to the Aura protection.

RUMBLE!

The clouds below me split apart as I saw the immense swarm of over four thousand machines descending at a rapid pace. They weren’t even moving to attack me; they completely decided on assaulting the people down below.

Because they knew that once they seized the land below, they would be able to easily scatter everywhere, dig underground, and hide! The sky is the only place where they cannot hide.

As I finally approached them and was within their range, they quickly turned against me, firing hundreds of beams of electricity against me.

“Fuckers!”

I placed my shield in front of me as I endured all the hits while moving forward. I used my Hundred Hand Aura to hold the shield in front of my chest, right below my nose; only my eyes could see what was in front of me. It looked rough but it worked.

Lastly, using my hands, I grabbed Gram, and then the Axe-Sword was summoned. Channeling Ki into their blades, I swiftly unleashed a devastating, wide-range technique.

I spun downwards, combining my Auras and my swordsmanship into a single storm. I also transformed and activated the [Divine Thunder God Body: Raijin’s Embodiment (SSS)] Skill to further gain more stats and a pseudo divinity of thunder.

Once the machines finally tried to evade, it was too late. After spinning and creating a thunderstorm around me by combining the clouds in the sky with my body, I released it all against them, swinging down my blades with all my force.

“{Thousand Blades}: {Heaven Splitting Thunderstorm}!”

BOOOMMM!!!

The thunderstorm encompassed thousands of foes at once, making them explode and frying their internal circuits; over half of the units died immediately, but around 1200 were still moving down, managing to evade the destructive blow.

“Dammit!”

That attack took everything I had to release it! My Ki was already down to nothing, so I quickly drank a Ki Restoration Potion and then tried to use my other abilities, inhaling the ki of the heavens and also using Demonic Stigmas and Celestial Marks, alongside Cursed Seals and the power of Hope, to gain more Ki out of the damage I took from the barriers I conjured on my familiars and Zero One.

The damage was accumulating nicely; although they didn’t take as much damage as I would have hoped, it triggered other effects, rapidly enhancing my stats and defense and increasing my energy output. Almost at full again, I quickly charged forward.

“Anna!” Song suddenly called. “Something is coming from above!”

“What?!”

And then I glanced into the skies above; a gigantic, golden hand made out of a pagoda building rushed towards me, titanic in size, aiming to grab us and crush us!

RUMBLE!

“EXTERMINATE ANNOYANCE. PROCURE TRUE VESSEL. COMPLETE DEMON KING TRANSFORMATION. ENSURE VICTORY OF THE MACHINE RACE.”

It was the Demon King!

[The Cosmic Throne {Mechanical Librarian} tells Song that he must not trust this evil woman that has slaughtered his innocent kindred.]

[The Cosmic Throne {Mother of Artificial Life} assures Song that they don’t have bad intentions and that if they let the machine become one with him, he’ll be able to be with his parents forever.]

“What bullshit are you saying?! Don’t believe them, Song! They’re monsters that want to invade this world and kill your parents!”

“A-Aah! I-I know!” he cried. “But they’re so annoying, my head hurts…! Uuaagh!”

They’re constantly sending messages to him; eventually the information will pile up into a sensory damage into his brain.

They literally want to melt his brain if he doesn’t obey!

Dammit, what can I do?

…

Wait!

Can I sponsor him?

Ding!
