I am Möbius's sister.

Chapter Fifty-Nine: Sirin, please explain this to me.

When Ling saw the large characters on the note, the anger that surged within her felt like it would turn the note in her hand to ashes. She gripped the note tightly, wanting to tear this mocking note into shreds.

But just as she was about to put her idea into action, she caught a glimpse of two lines of smaller text beneath the large characters. She had been too angry to notice them before.

So, Ling suppressed her anger and prepared to see what the two lines of writing meant. She unfolded the crumpled paper and carefully looked at the very small characters. Although the characters were small, the handwriting was beautiful and clear, so she could easily read them.

"Never believe in so-called gods, even if a 'miracle' befalls you. Never give up hope, even if hope seems to have been shattered." Ling read these words aloud, and after finishing them, a look of confusion appeared on her face.

These words were a bit hard to understand. What did they mean by "gods"? What was a "miracle"? And what about not giving up hope? Ling didn't understand any of it. She didn't know what the strange stall owner was trying to convey to her.

But it was probably just another trick on her. For some reason, Ling felt uneasy. After looking at the large characters above, she finally calmed down. Yes, this was all feudal superstition and shouldn't be believed.

Ling shook her head, clearing her mind of all distractions. Looking at the note in her hand, she thought for a moment before finally folding it up and putting it in her pocket.

Well, even though that weirdo was a con artist, she didn't take any money from her, so she'd forgive her. But...it's still a little strange. A moment later, Ling looked at Sakura beside her.

At this moment, Sakura was deep in thought, examining the bracelet on her wrist. The words that Sirin had said to her not long ago echoed in her mind. Those words were as alluring as a spell. Sakura took a deep breath and then resolutely put the bracelet on her wrist.

The moment she slipped the bracelet onto her wrist, a mysterious voice suddenly reached her ears, her heart pounded, and she realized she was stepping into a new world.

Meanwhile, in a secluded spot, Sirin, having shed her disguise, heard a system notification.

[Sakura] has joined the chat room.

Hearing the system's voice, Xilin's lips curled up slightly. As she expected, Sakura finally put on the bracelet. When it came to matters concerning her younger sister, no matter how dangerous, Sakura would try it.

With a gentle smile, Sirin opened the passage to the imaginary space, bringing out little Sirin and little Bella, who were now chatting and laughing. Sirin smiled and patted little Sirin's head, saying, "Mommy's done with her business, little Sirin, where do you want to go play next?"

Little Sirin blinked, thought for a long time, and then replied with a smile, "Anywhere is fine. Sirin has never been to an amusement park before, so Sirin wants to try them all."

"I see..." Celine pondered for a moment, then a brilliant idea flashed into her mind, and she suggested, "How about we go to the haunted house? I heard the haunted house here is really fun!"

"A haunted house? Sirin wants to go!" Little Sirin's face showed interest, and she immediately agreed. Little Bella, who was holding Sirin's little hand tightly, also had no objections.

"Isn't little Sirin scared? That's a haunted house!"

Little Sirin shook her head, raised her and Bella's hands in front of her, and replied, "Sirin, don't be afraid. Bella said she would protect me. She said she would always be by my side."

Upon hearing this, Celine was slightly taken aback. She could see the complete trust that Little Celine had in Bella. She wondered how Bella had managed to do it; their relationship seemed to be progressing very quickly. But that was a good thing, she thought. Hopefully, they could become loving and devoted sisters.

After combing Xilin's slightly messy hair, Xilin took her hand and left, heading towards the haunted house. This amusement park mainly features nighttime attractions, so it closes quite late, giving the three of them just enough time to have a good time.

The golden rays of the setting sun bathed the three of them, draping them in a golden veil, making them appear even more beautiful and warm. Joyful smiles radiated from all three faces. Celine swore this was one of the happiest times of her life.

While buying tickets for the haunted house, Sirin saw Sakura and Rei again. Even though she hadn't continued following Sakura, she still ran into her, which puzzled Sirin greatly. But perhaps this was just a strange twist of fate.

But she didn't plan to do anything. She had already done what she needed to do, and all that was left was to spend time with little Xilin. She didn't want to waste this precious time, so Xilin didn't react either. She bought tickets as usual and took little Xilin into the haunted house.

Inside the haunted house was a complex maze with some traps. Although there were very simple clues and guidance along the way, the three of them still fell into the traps a few times. Xilin didn't feel anything, but little Xilin was almost scared. If Xilin hadn't held Bella back in time, this place would have become a crime scene.

After a long while, the three of them finally came out of the haunted house. Although little Xilin was almost scared several times, she was still very excited. Little Bella, on the other hand, remained calm, as if the experience had not affected her at all.

However, Celine knew how agitated Bella had been when little Celine was nearly frightened not long ago. She was nothing like her calm demeanor now.

It seems that Bella really cares about Celine, Celine thought to herself.

They then went to play on several more amusement rides, immersing themselves in laughter and joy. After that, Xilin never encountered Ying and the other two again.

The three of them played until the amusement park was about to close before reluctantly leaving. Sirin ran to a secluded spot and took little Bella and little Sirin into the doll house. Before, Sirin was all alone in that place, but now little Sirin shouldn't be lonely anymore.

After doing all this, Xilin stretched, revealing her beautiful figure without an ounce of excess fat.

After habitually glancing around, Sirin opened a portal to her room. A moment later, the portal closed, and Sirin was no longer there, as if the cute girl from before was just an illusion.

……

"Heave-ho." As Sirin landed through the spatial portal, preparing to collapse onto her soft bed to reward her tired body.

A voice that Celine knew very well rang in her ears, and it wasn't far away; it was Möbius's voice.

"Cirin, you're back! Can you explain to me what these things are?"

Suddenly, a very bad premonition rose in Celine's heart, as if something terrible was about to happen.

She stiffly turned her head toward the source of the sound, and saw Mebius sitting on a chair not far from her, her long, beautiful legs wrapped in black stockings crossed, and in her hand she was holding something that Sirin was very familiar with—the decisive lingerie, and the yuri doujinshi that Sirin had bought at a comic convention.

Celine froze on the spot, her body stiff and unable to move.

Chapter Sixty: Be My Guinea Pig

At this moment, Sirin's body trembled slightly. She looked at Mebius not far away without saying a word, but you could see from her eyes that she was extremely nervous.

Xilin then forced herself to calm down. She opened her mouth slightly as if to say something, but the words stuck in her throat. She couldn't think of any reason to cover it up.

The atmosphere in the room became extremely strange and oppressive. Mebius remained silent, staring intently at Sirin, who stood not far in front of him. His sharp gaze seemed to want to peel away Sirin's clothes and see right through her. Under that gaze, Sirin felt as if she were naked.

This feeling was undoubtedly extremely unpleasant, but for now, Sirin could only endure it. Möbius was still waiting for Sirin's answer, while Sirin's mind was racing, searching for a solution.

However, before Celine could come up with a reason that would be enough to fool Möbius, the silence in the room was broken by Möbius's voice.

"Cilin, why aren't you saying anything? Let me guess if you're trying to figure out how to fool me?"

When Möbius's slightly flippant words reached Celine's ears, her heart skipped a beat. Her thoughts were completely jumbled; she couldn't think straight, nor could she utter a single word of rebuttal. Because what Möbius said was true, and she was indeed trying to figure out how to fool him. But how did Möbius know?

At that moment, Mebius's voice rang in Sirin's ears again.

"Are you wondering how I know what you're thinking? You silly girl, your eyes have already betrayed you. I don't even need to look closely to see what you're thinking written on your face. Your sister here is a genius, after all. You can't hide anything from me." Möbius chuckled, put down her crossed legs, and got off the chair with the two items in her hand.

Her legs, encased in black stockings, were flawless, without a single excess or blemish. The glimpses of fair skin peeking through them added a unique allure to her legs.

Mebius then strode toward Sirin, whose face was deathly pale and whose forehead was beaded with sweat from nervousness. Mebius's words had left her completely disoriented and unable to think of any good solutions.

As Mebius slowly approached, Sirin retreated gradually until she reached the wall with nowhere left to go. In desperation, she gritted her teeth and said to Mebius, "It was Alicia! Alicia gave me those two things!" As soon as she finished speaking, Mebius stopped in his tracks.

Then, in her heart, Sirin silently apologized to Alicia. Although it wasn't good to push Alicia to take the blame, it was an emergency after all, and she believed that Alicia would understand.

When Celine saw that Möbius had stopped, she silently prayed in her heart that her words would fool him. At the same time, she suppressed her nervousness and anxiety to prevent Möbius from judging her inner state from her expression.

Time passed slowly, and silence returned to the room. All Celine could hear was the sound of the wind blowing in through the half-open window, the ticking of the clock on the wall, and the rapid pounding of her heart.

Suddenly, the wind howled louder, whipping through Sirin's hair and also the ends of Möbius's. And then, another sound reached Sirin's ears: the sound of Möbius's footsteps.

Whether it was two or three seconds, before Celine could react, Mebius had already strode up to her, pinned her against the wall, and looked at her with a slightly amused smile.

At the same time, the fragrance emanating from Mebius wafted into Sirin's nostrils, turning her already chaotic thoughts into a complete mess. At this moment, she was extremely nervous, and she could no longer continue the prayer she had been praying in her heart.

A moment later, Mebius, standing in front of her, slightly raised the corners of his mouth, parted his red lips, and rang in Celine's ear with a clear, melodious voice: "Celine, haven't I taught you that you can't lie? Especially in front of me, lying won't work."

For some reason, Sirin seemed to detect a hissing sound from a snake in the voice, and Mebius's vision became even more glaring.

At that moment, Sirin stopped praying, because she already knew the outcome; she had no chance of winning. Möbius's voice rang in her ears again, as if announcing her final result.

“Disobedient children will be punished, you know~ Sirin, are you that disobedient child?” Mebius’s voice was dreamlike and entered Sirin’s ears. Sirin stiffly shook her head, and then she saw the slight upturn of Mebius’s lips.

She placed the two items in front of Celine.

Looking at the shameful clothes and the extremely embarrassing cover of the book, Xilin's face turned bright red, and she lowered her head without saying a word.

“Tell me, are these yours, Sirin?” Mebius waved the two items in front of Sirin’s eyes.

Under Möbius's oppressive gaze, Sirin finally admitted that it was hers. At this moment, she bit her lower lip tightly, her two small hands clasped together, her heart filled with unease. She didn't know how Möbius would react, and she hoped that he wouldn't hate her because of it. She didn't want to hear the notification sound of Möbius's favorability rating decreasing in her ears.

This will undoubtedly plunge her into despair.

A moment later, something unexpected happened to Sirin. A system notification sounded in her ear, but it wasn't a notification of decline; instead, it was...

[Mebius's favorability +1, current favorability 78]

The notification sound stunned Celine. She hadn't expected that Möbius's favorability rating would increase instead of decrease. Was this an unexpected surprise? Celine didn't know what to say for a moment, and Möbius's slightly seductive voice rang in her ears again.

"Cirin, do you really want to wear this dress? Who do you want to wear it for? Alicia? Or... me?" Mebius chuckled, completely unconcerned about Sirin's already flushed face.

"I...I..." Celine pursed her lips, her words stammering. Finally, she gritted her teeth and said to Mebius, "I don't want to wear this for anyone to see...but...if my sister wants to see it..." Celine didn't finish her sentence, but her flushed face revealed what she was about to say.

Looking at Sirin's flushed face, Möbius's expression became somewhat complicated. She felt a mixture of joy and worry. She was happy that Sirin had someone else in her heart, which meant Sirin would continue to cooperate with her experiments. But... that was also what worried her.

She knew that Celine understood what she wanted and what she was thinking; she knew that Celine was even prepared for her feelings to go unrequited. But as an older sister, she couldn't let her younger sister get too deeply involved. Her path was destined to be lonely, and that would sacrifice Celine's happiness.

Möbius looked at Celine with a complicated expression. Finally, she sighed deeply; she really was a terrible older sister.

She hugged Sirin, and the two items fell to the ground. Möbius leaned down and whispered in Sirin's ear, "In that case, you will be my guinea pig, my... sister."

Sirin paused slightly, a strange mix of emotions welling up inside her. She nodded, then gently rested her head on Möbius's shoulder.

Chapter Sixty-One: Sirin Takes the Initiative

The two embraced for a long time before separating, and even after they parted, Celine's face was still flushed. The alluring fragrance of Möbius seemed to still linger in Celine's nostrils, and she could still feel the warmth of his body lingering on her skin.

She kept her head down and didn't say a word, while Möbius reached out and, with a smile, helped her comb her slightly messy long hair.

When Möbius's slender fingers brushed through Celine's hair and lightly touched her scalp, Celine immediately felt a tingling sensation spreading from the top of her head. Although it felt a little strange, Celine found it very comfortable. She thoroughly enjoyed Möbius's caress.

“You really are just like a kitten~” Mebius chuckled, his hands still moving. “Since you’ve become my guinea pig, you’d better do your job well, my lovely little sister.”

"Duties?" Sirin blinked in confusion, tentatively asking, "Is it cooperating with the experiment?"

Mebius shook her head and continued, "Cooperating with the experiment is only one aspect. The most important thing is to be obedient. And..." Mebius paused, a dark light flashing in her eyes, and the corners of her mouth turned up slightly.

"And?" Sirin asked curiously, her curiosity piqued by Möbius's suspenseful behavior.

Fortunately, Mebius didn't linger for long. She took her hand off Celine's head, grabbed her hand, and pressed her back against the wall. This unexpected turn of events left Celine's eyes wide open, and she was momentarily stunned.

During this time, Möbius whispered in Sirin's ear, "You are my guinea pig, my dear sister. Since you have chosen to be my guinea pig, you belong to me. I will not allow you to fall in love with anyone else. Perhaps this will make you a little uncomfortable, but I cannot live without you no matter what, so you cannot leave me either."

Mebius paused, then released Sirin's left hand and gently stroked her cheek with her freed right. A strange blush appeared on Mebius's face as she said, "Your power is so captivating, your uniqueness is incredibly alluring to me. You know what I want most, you know where I'm looking, and to get there, your presence is indispensable."

Looking into Möbius's eyes, which were shining with an unusual light, Sirin didn't know what to say. She was certain that Möbius's feelings for her at this moment hadn't reached the level of lovers, but she could see a strong possessiveness in her eyes, and Möbius only had eyes for her.

This sense of contradiction could perhaps only be found in Möbius, that incredibly complex emotion. And this contradiction was precisely what she could exploit; when you consider someone family, it's almost impossible to develop any other feelings for them. Unless… you no longer consider them family.

It's decided! She's going to press her advantage! From a guinea pig to Möbius's bedmate!

After making this decision, Sirin's slightly confused eyes gradually became firm, and this sudden firmness surprised Mebius. At the same time, Sirin's right hand began to exert force, easily breaking free from Mebius's restraint.

While Möbius was still in a daze, she hugged his slender waist and, tilting her head back, said to him firmly, "I will never leave my sister! I will help her reach that ideal place! But I don't want to just be a guinea pig!"

Sirin's voice was incredibly firm, and looking into her unwavering gaze, Möbius was momentarily stunned. After a while, he came to his senses and stared at Sirin for a long time. Finally, he sighed helplessly, a slight smile playing on his lips, and slowly said, "A little lab rat can't have any other thoughts, you know. But... who told you to be my dear little sister?"

[Möbius's favorability +3, currently at 81. A shift in Möbius's emotions has been detected; please seize the opportunity. The King needs a talented bedmate.]

The two embraced again, just as the wind blew away the clouds and moonlight shone through the half-open window into the room, draping the two embracing figures in a silvery-white veil.
