The Protagonist's Sister Is Actually The Strongest

Ding!

[You have slain the Demonic Throne, {The Snake That Endlessly Devours Its Tail: Uroboros}!]

[An incredible feat! You have killed a Constellation while being a {Player} of the {First Awakening}!]

[You have earned a gigantic amount of EXP. The proper number cannot be shown due to its height and the current version of the System.]

[The System will be able to update itself once the {Second Awakening} begins.]

[Level Up!]

[Level Up!]

[Level Up!]

[Level Up!]

[Level Up!]

[Level Up!]

[Level Up!]

[…]

[Your Level has increased from Level 70 to Level 80!]

[All of your Stats have increased. You gained Bonus Stat Points and Skill Points.]

[You have reached Max Level.]

[You can now access the Job Class and Subclass Advancement Trial whenever you want.]

[The Trial will have its difficulty increased based on how strong you have grown.]

Oof, that’s not going to be easy, isn’t it?

The previous Trials were already challenging to the core, and I have no idea how much harder they’ll get once they calculate that I killed a damn Constellation into the equation!

[You have absorbed the Cosmic Soul Fragments of the Demonic Throne {The Snake That Endlessly Devours Its Tail: Uroboros}!]

[Your {Cosmic Heart} has absorbed the Cosmic Soul Fragments successfully!]

[A Special Evolution has been triggered within your {Cosmic Heart}!]

[The former Grade of Rank 0: Cosmic Dust has been upgraded to Rank 1: Novice Star (Initial Stage)!]

[You gained +5.000 Cosmic Energy.]

[All Stats have increased by +1.000.]

The Cosmic Soul Fragments were enough to help me advance the Rank of my Cosmic Heart?!

A Cosmic Heart is an organ inside every Constellation, the source of their power, which melds with their Cosmic Soul into the Dao Roots, Dao Branch, and then the Traits that pop from them, which are exuded as Radiance.

This means that my Dao Root and Dao Branch…!

[Your {Phantom Dao Root} has begun its rapid development due to the presence of a Rank 1 Novice Star Cosmic Aura.]

[Cosmic Energy is being absorbed to further improve its size and power.]

Within the depths of my Soul, I felt the phantom-looking Dao Root settle down much deeper, growing larger, although it had yet to create proper branches.

Because it wasn’t a Real Dao Root, but a Phantom Dao Root, it couldn’t exude its true strength until I ascended into a Constellation by gathering enough Stories to create a proper Epic.

There was a beautiful fruit surging from a root; it glowed with cosmic light, but it couldn’t quite form yet. It was most likely a new Trait!

[A New Trait has begun developing... Please continue forming your Epic for the Trait to fully develop into a new Ability.]

[The Surplus Cosmic Energy left has refined your Physique.]

[Your [Physique]: [Twelve Colored Stars Physique (Tier 2: Rank 7)] has grown to Tier 2: Rank 10!]

[You gained +300 Ki!]

[Your [Physique] can now be Ranked Up.]

[The power of Uroboros Traits has become yours.]

[You acquired the Absorbed Trait [Tail-Eating Snake (Epic Grade)]!]

[The Grade of the Absorbed Trait cannot surpass the limits of Grades of the User.]

[The Real Grade is {Mythic}, but it has been temporarily sealed to {Epic}!]

[There are two other Traits which have been temporarily sealed: [Devouring Gaze (Mythic Grade)] and [Cunning Viper (Mythic Grade)]

[To unlock the Traits, cultivate Cosmic Energy and grow stronger.]

Wait, I’m getting his Traits too?! I thought that wasn’t-

RUMBLE!

I felt an enormous power surging from my soul. One of the Phantom Dao Roots was forcefully stretched, absorbing a dark red essence, and turning into a monstrous demonic snake.

“SHAAAH!”

As it hissed at me angrily while still hanging by the branch, it began to bite its tail, remaining on an endless cycle...

Information about Uroboros entire life flowed into my mind, even if I didn’t want to see it. This was because I was literally absorbing a part of his own story, his myth.

FLASH!

I felt my mind being dragged into a different world, a world of wilderness and jungles.

Sitting in the middle of many leaves hiding behind huge boulders, there were dozens of small, white-colored eggs.

Crack, crack…!

Slowly, the eggs started cracking one after another as tiny green snakes hatched out of them, looking at one another innocently.

They slowly started devouring their own shells, while one of the eggs, the largest of them, began to exude an aura of crimson red.

Crack… CRACK!

The eggshells blew up as a different snake than the rest emerged, one with crimson scales and sharp, golden eyes.

It exuded a menacing aura like none of their siblings, and it was twice as large as them.

In simple terms, a mutated monster is born naturally stronger than its siblings.

“SHAAH!”

As if it had been born with the instinct to be aggressive, it leaped towards its siblings, opening its enormous jaws.

And it swallowed them one after another without letting a single one of them escape.

“Grrhh…”

The vicious snake licked its lips as it looked into the blue skies.

A spark of cosmic light surged from within them.

And a message appeared in front of it.

[Some Constellations have found you amusing.]

[The Cosmic Throne {Chaotic King of Brutality} smiles at your ruthlessness from birth.]

[The Constellation has sponsored the Privilege: [Apex Predator (S Grade Privilege)]!]

A cosmic power surged from within the snake, its golden eyes glowing with power…

“Shaaah! Shaaah!”

It celebrated its new power, and it quickly began sliding across the jungle.

The rise of a new Apex Predator quickly engulfed the entire Jungle, which ended up being a world of its own, a world without people, full of Magic Beasts fighting for supremacy.

It fought and devoured as many monsters as possible, slowly growing more intelligent and cunning while growing larger and stronger.

It was ruthless and never cared about its own kin, eating anything on its path, no matter what they were.

A single serpent engulfed an entire world by itself, a world that no Constellations other than a very bored one noticed.

Eventually, because it had grown too strong,

FLUOSH!

A starlight portal opened on its path one day after it was starving so much that it was beginning to bite its own tail.

[The Cosmic Throne {Chaotic King of Brutality} has opened the Gates to [Hell Number-999]

[The {Hidden Scenario: Rising of the Devourer of Worlds} has begun.]

[The Constellation invites you to bring destruction and chaos and to devour it all.]

[At the end of the road, a path to the stars will be revealed.]

“Shaaahh…”

The snake greedily entered the portal, continuing its endless rampage to eat it all, devouring demons, and demonic beasts, and surviving countless battles.

Eventually, it invaded the lowest layers of this Hell, devoured the Demon Lords, and eventually met the Demon King.

“Y-You! What sort of calamity has Lord Lucifer thrown into our world now?!”

The Demon King greeted the gigantic snake with eyes filled with wrath and frustration. It seemed to be a gentle Demon King, one that cared for its subjects.

And that’s why his Hell was targeted.

“Lucifer does not need weak-hearted fools like you to join him in the Primordial Hell.” Uroboros could now speak, smiling greedily as it licked its lips. “Your World will end now. I am the harbinger of destruction, the devourer of all. My purpose is to devour everything.”

“YOU MONSTER!”

The Demon King of Hell 999 battled against Uroboros for several days in a row, his powers seemingly equal to his.

However, Uroboros possessed a cheat; devouring his own tail allowed him to regain health and mana, possessing endless stamina.

Over time, the Demon King’s energies wore off, and while screaming in horror, he was devoured too.

“Lord Lucifer…! Why?! WHYYYY?!”

CRUUUNCH!

Gulp.

Uroboros swallowed the Demon King, its power rising even further, surpassing the levels of even Death Apostles.

And then, several messages appeared.

[The {Hidden Scenario: Rising of the Devourer of Worlds} has been completed.]

[You have devoured all life from Hell 999!]

[Your Epic has fully evolved into a Legend!]

[Your Soul has ascended into a Cosmic Soul!]

[Your Cosmic Soul has become one with the Cosmos, another Star amidst countless ones.]

[You are now a Constellation.]

[The Hell 999 World has begun to slowly be digested by the Void Rulers.]

[The Cosmic Throne {Chaotic King of Brutality} is overjoyed.]

[He invites you to sit at the side of his throne.]

[However, to reach that throne, you must first dethrone another.]

“Lord Luciferrr…” Uroboros smiled. “I shall sit at your side… Yesss… No matter what!”

Uroboros transformed into a gigantic beast, evolving into a Constellation as its Epic was fully developed into a Legend, the Snake that Eats its own Tail.

It was transported into the Cosmic Valleys, traveled across countless stars, devouring more worlds by bringing Calamities to them following the Awakenings and Scenarios, and eventually...

It reached the Realm Beyond, where it met Fenrir and various other “underdog” Constellations trying to make an uprising.

He acted friendly to gain their trust, and when it was finally time, he betrayed his friends, allowed Fenrir to be sealed and become a Fallen Constellation, and defeated Beelzebub, gaining the throne of the Archdemon of Gluttony.

“GYAHAHAHAHA!”

His laughter echoed through the visions until they broke down into screams of agony. His Myth, which had evolved from a Legend, came to an end when he overstepped his boundaries and didn’t think about the consequences of his actions.

Well, seeing how he lived, he never truly did. It was born with power, sponsored by nobody else but Lucifer, and always devouring and bloating itself with anything it found.

It never learned what defeat truly was—or to be weak.

Uroboros lack of experience might have become its greatest weakness.

Once the vision ended, I opened my eyes within Neberius Soul Scape, which had stopped falling apart because I used my Cosmic Aura to hold it still.

Ding!

[You have fully watched the {Myth of the Snake that Bites its Own Tail}!]

[The {Myth} have been fragmented into two halves; you have absorbed one.]

[Your {Epic} is beginning to develop even further.]

[However, the shell to contain it is far too weak, and the restrictions of the {First Awakening} are weighing down your development.]

[To further develop and unseal these powers, grow stronger.]

Yeah, yeah, now give me the goodies; I know there’s more than that.

Ding!

[You have received [Half of Uroboros Cosmic Corpse (??? Grade)] x1!]

[You have received [Crystalized Cosmic Soul Shard (??? Grade)] x1!]

[You gained +100.000 Plot Points.]

[You received the Title: [Constellation Slayer]!]

[You learned the Skill: [Demonic Snake’s Gluttony (SSS): Lv1]!]

[The High Administrators have been closely watching you.]

[They have temporarily closed the channels allowing Constellations to send you sponsorships, gifts, or messages.]

[They have invited you to a private meeting.]

[Accept?]

[Yes] [No]

This message, when it was received, felt strange.

It was as if time itself had slowed down to an incredible pace.

I felt a huge pressure as powerful eyes gazing at me from Higher Dimension oversaw my every move.

It wasn’t as if I had any options here.

“Yes.”

[You have accepted the private meeting.]

[Teleporting the user’s consciousness to the Private Meeting Room.]

FLASH!
