[Comprehensive] Songs of the Six Trillion Years of the World

Large pieces of crystal weapons were suspended in the air, and the sharp blades surrounded Tan Tian.Not only that, Aiya herself also appeared in front of Tan Tian, ​​with one red and one blue eyes bursting out with murderous intent without mercy.

"Wait! Aya—"

Ao seems to want to stop her irrational behavior.After all, death was the black-haired Chuxue's own choice, and the other party just didn't know it and happened to be the one who killed her—after all, there was another person on Chuxue's candidate list.

But before he reached out to stop him, Aya had already trapped Aiou in the crystal cage without any explanation.

"Sorry, but even Ni-chan can't stop me this time!"

As if echoing the girl's words, the black-haired god-judgment boy activated his [Origin].In an instant, countless intact or incomplete swords gathered into a torrent, mercilessly bumping into the crystal weapons made by Aya.And Aya was not to be outdone, and the crystals under anger became even more aggressive.Two huge vortices, one silver and one purple, collided with each other, and the impact of the explosion even overturned the willow trees on the shore.

Not only that, the black-haired boy and the peach-colored long-haired girl also held long-handled swords and fought one-on-one.The crystal gradually extended from the center of Aya's palm into the shape of a sword, and the clear and clean crystal suddenly became a bit more chilling at this moment.

Just before Tan Tian was trapped by crystals emerging from the ground, and just before Aya's crystal katana was about to hit his head, a tall and thick spear suddenly appeared, stopping the black-haired boy and peach-colored long-haired girl in the middle.

"Ah, I managed to barely catch up~"

The woman's voice is clear and cheerful, except for a little tired panting caused by rushing on the road, it can almost be said to be sweet.The heavy long spear standing between Tan Tian and Aiya trembled slightly, and even the purple ribbon wrapped around his body was blown slightly up in the air by the burst of spiritual power.

That is Tonbokiri, one of the three famous guns.

The oblique square grid on both sides of the gun body presents a dark purple color, and the thick blade is like a wide-edged sword. In addition to the blade body that is 43 cm long, the handle length is as long as 6 meters. The length... But such a powerful pistol is not half as good as the young girl in front of him.

After catching a glimpse of the white-haired Chuxue's face, Aya's attack subconsciously stopped.And after seeing the shoulder-length silver-white short hair of the young girl who judged God, Tan Tian was so frightened that he dropped the knife in his hand.

"……senior?!"

Sighing slightly, the white-haired Chuxue nodded to him, confirming his guess: "It's me. But I just changed my hairstyle. Why do you show such an expression that the sky is falling?!"

Tan Tian turned his head and said, "...No, it's just that Xiao Xiao was frightened."

Twitching the corners of her eyes, Chuxue finally couldn't help complaining: "Before you say that, pick up the knife you dropped!"

With a slight flick of the long|spear with spiritual power, the Wuhua Taidao that fell to the ground was sent back to Tan Tian's hand.Afterwards, Chuxue, who had white hair and blue eyes, turned to look at Aya.

"Sorry... As a matter of fact, two identical souls cannot exist on the same timeline and worldline. Therefore, I am also responsible for the death of the elder sister of your brothers and sisters." As she spoke, she rolled her arms With a gun flower, the dragonfly was cut and taken back.

White-haired Chuxue approached Aiya empty-handed like that, making Tan Tian unable to hold back his voice.

"Wait! Senior... Senior?"

Hearing Tan Tian's call, the white-haired god-judgment girl turned her head.Although the expression on her face was a bit tangled, she quickly revealed a smile that was not much different from before.

"Anxin, Anxin, the life I owed to Chu Rui has already been returned. So, you who are 'Tantian' now, can't stop me~"

The black-haired boy's eyes widened instantly, and after realizing the name Chuxue said, he finally realized something.But before he could stop him, the white-haired Chuxue had already spontaneously erupted the little dark power that had been left on her wrist.

Because it was the same person, when she died, part of the black-haired Chuxue's memory and soul still flowed over.

Aya's eyes widened. At this moment, even though Chuxue in front of her was a God-inspector who had not fallen into darkness, even though her eyes and hair color were different from the big sister she remembered, she still recognized her. Who does that look belong to.

"……big sister!!!"

Taking advantage of the opportunity of Aya's mental relaxation, Ai Ou finally got rid of his sister's imprisonment.He trotted over, but saw the expression on Bai-haired Chuxue's face.

"...Big sister, is it?"

The darkened spiritual power surged with a dark breath, and dots of blue-blue ominousness wandered around.The white-haired Chuxue obviously took the risk of using her own body as a carrier, and then relied on her own little remaining dark power to stimulate the part of the black-haired Chuxue's soul in her body.

She reached out and touched Aya's forehead, and her cold hands seemed to become warm after touching those peach-colored hair.After noticing that Io was here too, she narrowed her eyes and gave a small, weak smile.

"Ah~ I'm still thinking, Aiou, when will you call me 'big sister' like Aya~"

"Crap."

Although she turned her head away, Ai Ou still threw herself into Chuxue's arms like Aya.

"...I'm sorry, I'm really sorry. Big sister. I couldn't save you, I'm really sorry..."

"There's no such thing!" As she said, Chuxue gently stroked the tops of the twin siblings' heads one by one.

"The so-called 'rescue' is the concept of 'rescue' after the person concerned makes a request for help, and then helps them. From the very beginning, I didn't intend to ask you two for help, so——No If you can save me, don’t say it again. My death is my own choice, it has nothing to do with you, and it has nothing to do with those judges..."

Gentle whispers, just like the stories she told the twins at night.

It's just that what she said this time was her own last words.

"I'm really sorry for not being able to say goodbye. But, Aio and Aya, even if I'm gone, we must live strong!"

"Sometimes I often fantasize late at night. It would be nice if I could get to know you earlier. It would be best if we meet before everything happens. In this way, I can protect you from having a distorted childhood. The sword will protect you firmly behind you... But, why is there no if in this world?"

"I want to protect you, but I can only teach you how to face problems on your own. The more you do this, the further you will be pushed away... If I can, I really want to be an umbrella that you can rely on as much as you want."

Her voice has become unstable.

But even so, she still smiled and hugged the twin siblings in her arms.

"I really want to see you... living life with unscrupulous smiles..."

The next moment, the hands stroking Ai Ou and Aiya stopped.

--left.

——This time, he really left.

"Feel sorry."

It was still Chuxue's voice, but the tone and intonation were no longer that of their big sister.

The short, hallucinatory farewell still made the twins burst into tears.Chuxue's cheeks were also wet with tears at some point.

"Even if the same person makes different choices, the person he will become in the future will be different. I think, even if I choose to fall in the dark, I probably won't be the big sister who belongs to you. But, I still want to replace that Let me tell you something - 'It's really great to meet you'."

The crystal world collapsed.

All that remained were the two crying children.

***

Without saying anything, the white-haired Chuxue bid farewell to the twins and walked back.It was rare for Tan Tian to be a little awkward, and there was obviously a lot of hesitation in the eyes that peeked at her from time to time.Regarding this, Chuxue knocked him on the head moderately.

"It was agreed in advance that I have already paid back the life I owed 'Chu Rui'! And you are 'Tan Tian' now, if you care about so much, I will go after Zhu Yang and pry your corner."

"Hey! Why would Senior know..."

"Because I'm not blind."

She lowered her head and stared at her palms.Opening and clenching her five fingers, this movement seemed to make her discover something, so that this beautiful silver-white haired god-inspector suddenly showed a smile as if a conspiracy had succeeded.

"Senior, has anyone said that you look terrible when you smile now?"

"Yes, but that's not the point~" She tilted her head, and said, "It's probably because another person who violated the law took away the possibility of dark fall, so in the current period of time, I'm afraid I'm just destroying the world." It won't cause a dark fall—"

Seemingly aware of something, Tan Tian stayed away from her calmly, and said, "...What are you doing?"

Although she didn't want to admit it, the memory of the black-haired Chuxue still had a certain impact on her.The white-haired God-inspector girl raised her hand with a smile, and the thick pistol dragonfly appeared in her hand in an instant.

"It's nothing~, I just feel that I should give the twins a gift for the one who helped pay back the life they owed~"

***

She heard the sound of the world collapsing.

The sunset was silent, the night fell, and the bright and grand funeral set off a storm.Red and black holes appeared in the sky, pouring out the black mud of hell.They were irresistible, overwhelming, and in them, the pretty girl with silvery white hair and blue eyes turned.Except for the wrong hair color and eye color, her appearance is exactly the same as that of Chuxue.

No, to be precise, it should be the first snow before being corroded by the curse of the dark fall.

She raised her hand and pointed to the hole in the sky.The poured black mud material fell down on Fuyuki City, destroying everything touched by the black mud.

"World historical record - this city will be destroyed by the summoned Holy Grail. However, considering the dual roles in the Holy Grail War, there is no way to trigger the dumping of the black mud in advance. Because there are too many variables, the consequences are too great. Huge, so the history of this period of time will probably be reset..." At this point, she smiled at the twins and continued: "So, even if you make some changes quietly, it doesn't matter~"

The twins looked at each other, although they didn't understand why the white-haired Chuxue would suddenly talk to them, but since the other party had the same face as the black-haired Chuxue, Ai Ou and Aiya still felt a little close to her.

"Let's go, I'll send you two away."

Just before leaving, she quietly patted the back of Ai Ou's hand.

Aio: "???"

White-haired Chuxue raised her index finger at him, shook her head with a light smile, and said, "Although there is no way to return your big sister, it's okay to give you an r~"

Aio: "!"

Aya: "Ah!"

Chuxue: "...Wait! Why do I suddenly feel like you guys forgot about him?!"

Aya: "...This, too many accidents... accidentally..."

Chuxue: "Then do you still want more? I am also very tired of creating this kind of back door. It is too late to give up now."

Io: "No! We will!"
