I am Möbius's sister.

I, Möbius's Sister (Author: Lily and Citrus)

Introduction:

In the pre-Honkai era, I was Mébius's younger sister, named Sirin. Although we weren't blood-related, we were closer than blood-related sisters. My older sister was very good to me and often gave me delicious food.

Until one day, I unwittingly awakened the Herrscher's abilities and even received a belated cheat code.

From then on, the way they looked at me became increasingly strange. And the world became increasingly strange too. "Alicia, save me! My sister's going to make me do experiments again!"

Chapter 1: I'm really not the Second Herrscher!

"Name?"

"Cirin".

"identity?"

"Dr. Möbius's sister."

……

In the dim light, a fully armed researcher was questioning the girl opposite him in a cold voice.

The girl had long, flowing purple hair and bright gold eyes with an X-shaped mark in the center, giving her an air of unparalleled nobility.

The girl wore a snow-white dress with lace trim and floral patterns. The white dress complemented her fair and delicate skin, making her appear even more radiant.

This beautiful and delicate young girl had her hands bound by a specially made handcuff, like a bird whose freedom had been restricted.

The girl's name is Xilin. Just the day before, she was happily drinking tea and eating bread at home. Who would have thought that she would be caught like a moth drawn to a flame today? Can this only be described as the unpredictability of life?

Sirin has a secret she has kept hidden for a long time: she is a reincarnated person, but she doesn't have many memories of her previous life. She doesn't even know if she was male or female. However, she still clearly remembers this world—the Collapsed World—and some of the plot of this world.

It seems that while she was playing this game, she was defeated by divine justice and then reborn here, becoming a pitiful girl adopted by the Mebius family. She looks exactly like the Second Herrscher from that future era, even sharing the same name.

She had a relatively happy first half of her childhood, but things got worse and worse as time went on. Her father in this life was taking some kind of drug, and due to the side effects, his temper became increasingly irritable, as her sister Mebius told her.

After that, her sister Mebius took her away from that home, and life got better and better. She had meat to eat every meal, but the time she spent with her sister also decreased significantly.

Knowing a little about the plot, she knew that her sister had joined the Fire Moth.

I thought life would get better and better, and would continue to be peaceful like this.

But... who would have thought that just last night, she inexplicably gained the abilities of the Second Herrscher, even though the Second Herrscher was already dead and her body had been secretly dissected by her sister.

Moreover, there were no signs on her body, no Herrscher transformation, and no major collapse. She only showed Herrscher reactions and gained the abilities of a second Herrscher. This is simply outrageous, outrageous to the extreme!

The most outrageous thing is that her cheat ability is only now awakening, even though she's been in this world for so many years!

In short, she has now been discovered by the Moth of Fire and brought here for interrogation. If she hadn't shown no hostility, no aggressive tendencies, and hadn't caused a major collapse, it probably wouldn't have been as simple as just putting on some special handcuffs.

"Um... I'm really not the Second Herrscher." Because her mouth was dry, Sirin's voice was a little hoarse, and she sounded even weaker.

The researcher looked at Sirin, who was hanging her head and looking dejected, for a moment, then sighed helplessly and said, "We don't want you to be the second Herrscher either. We've detected that the global Honkai energy level has increased slightly, and the Third Honkai Impact is approaching. We can't deal with two Herrschers at the same time."

"Then... can you let me go?" Little Sirin raised her head and winked at the researcher, her long eyelashes fluttering like butterfly wings.

"I'm sorry, we can't release you right now, because we can't be sure if you really pose no threat." The researcher said decisively, leaving no room for discussion. Having witnessed the terrifying nature of beings called Herrschers, they naturally needed to be more careful and cautious.

“Hmm… alright then…” Seeing that the researcher had rejected her so readily, Sirin didn’t say anything. After all, she could understand. At the same time, she was glad that this was not the time when humanity had suffered heavy losses. She didn’t have to worry about being killed by the fearful soldiers. Of course, she wasn’t powerless to fight back.

She could break free of the handcuffs at any time if she wanted to, but she didn't want to increase her own threat level, as that would definitely lead to her own demise. It was safer to play it safe and wait for her older sister to come and save her.

Seeing that Xilin didn't show any significant emotional fluctuations, the researcher breathed a sigh of relief. To be honest, he had been on tenterhooks the whole time, fearing that the girl in front of him would turn into a man-eating 'big bad wolf' and kill him with a single swipe of her paw.

Don't let Sirin's petite stature fool you; her energy level is definitely that of a Herrscher. It would be strange if he wasn't afraid!

Fortunately, this girl seemed different from those Herrschers, more like a human, which greatly reduced the danger.

"Take her to the house arrest room." The researcher stood up from his chair, gave a few instructions to the armed soldiers standing on either side, and then hurriedly walked out of the interrogation room.

He had only been out for a short while when he saw a pink-haired girl walking towards him. This pink-haired girl had a curvaceous figure and a beautiful face.

"Lady Alicia." Upon seeing the pink-haired girl approaching him, the researcher was taken aback at first, then respectfully greeted her.

The girl called Alicia smiled and nodded, then walked towards the interrogation room. Just as she reached the researcher at the door, Sirin was led out by the two soldiers.

"Lady Alicia".

"Lady Alicia".

The two soldiers spoke in unison, while Sirin looked at the pink-haired beauty in front of her with great curiosity.

Alicia? She seemed to remember that name from her past life.

Just as Sirin was recalling her memories of her past life, Alicia suddenly smiled and said, "You're Mabius's sister? What a lovely girl! I'm almost tempted to have you as my sister."

“Lady Alicia… um…” The researcher standing to the side stammered as he watched Alicia’s actions.

"Okay~ I got it~?" Alicia glanced at the researcher beside her, waved her hand at him, seemingly already knowing what he wanted to say, then squatted down, patted Sirin's fluffy little head, and said with a hint of regret, "It's a pity, they won't let me talk to you much, but we can chat later~?"

After saying that, Alicia patted Sirin's head again, then hummed an unknown lullaby and turned to leave, leaving Sirin completely confused and having no idea what Alicia wanted to do.

After Alicia left, Sirin was also taken to the house arrest room by the soldiers.

……

In the house arrest room

Xilin sat obediently on the bed, seemingly lost in thought. In this room of confinement, there were four cameras, providing 360-degree surveillance without blind spots, and someone was watching the screen in the monitoring room every moment.

Celine was naturally aware of this, so she sat on the bed in a daze without saying a word. Or rather, she was exploring her body, or simply getting familiar with her newfound abilities and the belated "golden finger" (cheat code).

Before Sirin was a large light screen, invisible to others, which Sirin was controlling with her will.

After taking a quick look, Xilin felt that this thing was quite similar to the system in her memory. It had an ability panel and status bar, but it didn't have a task system, nor a favorability system, nor a card-drawing system, and there was also an unlocked chat room system, the purpose of which she didn't know.

Just as Xilin was preparing to study her system more deeply, the light screen in front of her suddenly turned white, and then several large characters appeared on the screen.

You will eventually be crowned king, reigning supreme over the world.

[Countdown to the End of the World, 3/14]

The world line is distorted...

The main storyline [Humanity's Tragedy] has begun.

After these large characters slowly appeared and then slowly disappeared, the light screen returned to its original state, except that the chat room, which was originally locked, became open.

Chapter Two: Snake, My Snake

Sitting on the bed, Xilin swung her legs, which were covered in white stockings, and seemed to be in a good mood.

The light screen in front of her displayed Möbius's level of affection for her. After exploring, she discovered that the system did not lack a card-drawing interface, but rather that the method for obtaining card-drawing opportunities was extremely demanding, and the number of draws was very limited.

The first way to obtain it is to trigger a special storyline. Successfully achieving a perfect score will grant you one chance. The second way is to romance a special character and raise her affection level to 80. This will grant you one chance. If you can reach 90, you will get another chance.

Although it feels a bit like a romance system from a slice-of-life story, it's actually not bad.

Moreover, the rewards from this gacha are quite powerful. Although the gacha interface was hidden, after careful exploration, Sirin still found a way to enter the gacha interface by taking a shortcut, and was able to see a small part of the card pool.

The grand prize in the first round of the card pool was a die, a 100-sided die. Its strange shape reminded Sirin of tabletop role-playing games, and the way this die was used was indeed inseparable from tabletop role-playing games.

[[All-or-Nothing Dice]: This is a die with immense power, capable of altering the rules. When something fails, you can use it to get a second chance, but if the result is a normal success or failure, the original outcome may become even worse.]

The effect is also described below.

[Note: This item can only be used once. The default value is 50. A value of 26-50 is a normal success, a value of 11-25 is a difficult success, a value of 2-10 is an extremely difficult success, a value of 1 is a great success, and a value of 96-100 is a major failure. The quality of the check result will affect the severity of the rule change.]

Without a doubt, this die is an extremely powerful item, worthy of its grand prize name. In addition to this grand prize, the other items are also very useful, such as the pill that can instantly restore full health and the necklace that can lock health for up to an hour.

Sirin desperately wanted every item in the prize pool, but unfortunately, the chance to draw cards was too rare, so she could only stare longingly at the items in the pool.

The good news is that Mebius has a 62% affection level for her, which is the highest among the current targets, although it is still limited to the realm of familial affection.

The bad news is that Mebius is her sister. Although they are not blood sisters, she still can't bring herself to hurt her after so many years of getting along. After thinking it over carefully, Sirin can only wait for the special plot to be triggered. Anyway, this thing doesn't have any forced function.

After browsing the system interface for a while, Xilin's gaze fell on the chat room that was marked as not open.

It seems she has to activate this thing manually, but is it really a good idea to activate it so early?

Chat room? This thing reminds me of a chat group. Could it be something similar?

Should we turn it on or not? Sirin pondered.

Just then, the sound of an iron gate opening rang out. Xilin had a sudden thought, and without making a sound, she put away the light screen, deciding to think about it some more.

After retracting the light screen, Xilin looked in the direction of the sound and saw a girl with long, light green curly hair, wearing a white coat, walking forward under the protection of two soldiers.

“Sister!” Yes, the person who came was Celine’s sister, Mebius. Instinctively, Celine wanted to get up from the bed to give Mebius a hug, but her hands, which were bound by handcuffs, prevented her from doing so, and she had to sit back down.

Although Sirin didn't come over, Möbius quickly arrived in front of her, and then placed his hand on her shoulder.

"Sirin, tell your sister, do you... really possess the abilities of a Second Herrscher?" Sirin paused slightly upon hearing Mébius's question. Mébius's voice seemed tinged with excitement, as if he were suppressing something.

After thinking for a moment, Sirin decided to tell the truth, so she nodded.

Upon seeing Celine nod, a glint seemed to flash in Möbius's eyes. She took out an experimental notebook from the pocket of her white coat, then pulled out a pen, and casually dragged over a chair in the confinement room to sit directly opposite Celine.

"Sirin, tell your sister how you obtained the Second Herrscher ability. Were there any unusual circumstances?" Mebius asked Sirin in a gentle voice, her eyes filled with excitement.

Hearing Mebius's question, Sirin didn't know how to answer for a moment. She didn't know where she got her Second Herrscher ability. Although she knew it was related to the system, she didn't know how the system did it.

After a long silence, Xilin shook her head and said, "Sister, I don't know how it came about. I just woke up after a nap. There haven't been any unusual circumstances so far."

Upon hearing this, Mebius didn't say anything. Although she felt sorry about the result, it wasn't unexpected. It would be really strange if it were so easy for humans to evolve to the Herrscher level.

Although Sirin is an isolated case, it at least proves that humans have the opportunity to evolve to the level of Herrscher, they just don't know how to evolve.

"Sister, I'm really not the Second Herrscher." Sirin raised her bound hands, grabbed Mebius's white coat, and looked at her with a pitiful expression.

Seeing this, Mebius reached out and patted Sirin's fluffy head, smiling as she said, "Don't worry, I know you're not the Second Herrscher. I'll get you out of here; after all, you're my little sister~"

For some reason, being stared at like that by Mebius made Sirin feel a little uneasy, as if something bad was about to happen to her.

Suddenly, a soldier rushed over and handed Möbius a piece of paper the size of an A4 sheet of paper with some words written on it.

Mebius frowned as he looked at the words on the paper, and crumpled it into a ball with force.

Mebius glanced at the obedient Sirin on the bed, a slight smile playing on his lips. Then, his face fell as he looked at the soldier beside him and said in an icy tone, "Go back and tell those guys that if they don't want to deal with two Herrschers at the same time, they'd better give up those filthy thoughts in their hearts."

Upon hearing this, the soldier was taken aback. He felt uncomfortable under Mebius's sharp gaze, but he dared not say anything. He could only respond to Mebius and then hurriedly left.
