I am Möbius's sister.

For some reason, Seele seemed to detect a hint of dissatisfaction in the tone of her other self.

However, she didn't care too much, and replied somewhat hesitantly, "Well... I think it's better not to... After all, it looks a bit like I'm doing this and that to myself, and it feels... a little strange... Besides, I still think that these kinds of intimate things should be done with someone you like..."

Before Seele could finish speaking, she was interrupted by [Seele].

[So you don't like me? Humph! Then go find your Bronya sister! You don't like me anyway!]

After saying that, [Seele] cut off the communication, and no matter how Seele called out, she wouldn't come out, which made Seele very anxious. She didn't know what she had done wrong. However, at this moment, [Seele] looked like a child throwing a tantrum.

After settling Seele in and arranging a single dormitory for her in the Firemoth, Sirin and Mebius went together to the Honkai Beast storage warehouse.

Having received prior notification from Mebius, and under Sirin's remote guidance, the warehouse management staff specially created a large space on the lowest level of the warehouse, filled with the high concentration of Honkai energy required by Sirin.

Because this requires an excessively high concentration of Honkai energy, in order to avoid unnecessary losses, such as small-scale Honkai outbreaks, some Honkai Beast corpses were specially moved away to keep the Honkai energy in the warehouse within a relatively safe range.

The two successfully stored the oversized Honkai Beast. At Mebius's request, a large piece of the Honkai Beast's body tissue was sent to the laboratory directly under Mebius's control. Some of Mebius's subordinate laboratories and research institutes also received a sample because of Mebius.

After dealing with these matters, Sirin accompanied Möbius on an experiment about imaginary space. This experiment was initiated and led by Möbius, and there were quite a few researchers involved, which made Sirin a little nervous. However, with Möbius's encouragement, the experiment proceeded smoothly.

When the experiment ended, it was already the evening of the third day. During these past few days, Möbius and Mebius had been working tirelessly on the research, like robots. By the time the research was finished, both of them had dark circles under their eyes.

Compared to the work of Möbius and May, Sirin's work was quite easy. She only needed to create an imaginary space for these scientists to study, which was a piece of cake for Sirin.

Even after creating an imaginary space, she can go to sleep directly, and even while asleep, she can maintain the existence of the imaginary space.

In this situation, Sirin's mental state was exceptionally good; compared to that group of scientists who were so enthusiastic that they didn't want to rest, she was practically a goddess descended to earth.

The research over the past few days has been very successful. With Sirin's active cooperation, these scientists have figured out the connection between the imaginary space and the Herrscher's power, and have gained a preliminary understanding of some characteristics of the imaginary space.

Because of Sirin's boundless energy, they even took a brief look at the Sea of ​​Quanta, something that wasn't originally within the scope of this study.

While the scientists were excited, this undoubtedly added a significant amount of work to their workload.

When the experiment ended, some of the weaker scientists were carried away on stretchers, while Möbius fell into a deep sleep and was carried away by Sirin. As for Möbius, whether he was exceptionally gifted or something else, he was fine except for being slightly tired, and compared to the scientists around him, he was practically a superman.

Then Kaiwen came to pick Mei up.

After carrying her older sister home, giving her a quick clean-up, and placing her on the bed, Sirin asked Isa and Ekaterina to guard the door while she climbed into Mébius's bed and fell asleep holding Mébius.

Ekaterina protested to Sirin that she wanted to sleep with Sirin, but her idea failed due to Sirin's rejection, and she could only wait at the door.

Inside the room, Sirin nestled in Möbius's arms, a happy smile on her face. Möbius's embrace was warm, which Sirin loved, especially the milky scent.

Chapter 163 Why Don't You Join In Too?

Three days later

"Ah~ what a beautiful day~" Sirin sat up from her bed and stretched. Although she, as a Herrscher, didn't need to sleep, sleeping still felt quite nice.

Rubbing her eyes, Sirin looked around and breathed a sigh of relief when she saw no one. Yekaterina had been staying at her house for the past three days, which meant she would raid her house every night. Last night, she had specifically locked the door, and it seemed to have worked; the door had deterred her.

With a light shake of her head, Xilin got out of bed, her fair little feet adorned with a pair of pink bunny-ear plush slippers, looking incredibly cute.

Xilin picked out a beige dress from the closet, grabbed a pair of white lace-trimmed ankle socks, and then skipped and hopped to the dressing mirror to change.

After getting dressed, Xilin twirled in front of the mirror once more, then nodded in satisfaction.

"I'm so cute today too~" Sirin boasted without any attempt to hide it, and all her boasting was true.

Sirin tidied herself up a bit, then headed for the door. She still had to take Ekaterina to see Möbius for surgery today, so she couldn't slack off.

Upon reaching the door, Sirin opened it to go out, but as she did so, her sharp eyes noticed something leaning against the door falling to the ground. Seeing this, Sirin quickly stopped and looked closely at the object outside. She then realized that it was none other than Ekaterina!

"Ekaterina!? What are you doing here?" Sirin exclaimed in surprise.

Whether it was Sirin's action of opening the door that startled Ekaterina, or Sirin's exclamation that startled her, Ekaterina woke up very quickly, rubbing her sleepy eyes, and greeted Sirin.

"Sister Xilin, you're awake! Good morning."

"Good morning... Wait! Why are you leaning against my room door?" Sirin crossed her arms and looked at Ekaterina with a puzzled expression.

Upon hearing this, Ekaterina gave Sirin a rather resentful look and said, "It's all because you wouldn't open the door, Sirin..."

"So you just slept against the door all night?" Sirin frowned.

"Ah."

After staring at Ekaterina for a long time, Sirin finally sighed helplessly and said nothing more.

After thinking for a moment, Sirin said to Ekaterina, "How about this, I'll allow you to sleep with me when my sister isn't around, but don't touch me, okay?"

"Understood!" Hearing Sirin's words, Ekaterina's heart was filled with joy and sweetness.

Seeing Ekaterina's excited expression, Sirin felt a little helpless. She had long realized that this little girl had special feelings for her, but her heart had already been given to her older sister, so no matter how hard Ekaterina tried, it was to no avail.

After all, Celine is very devoted; it's just a mystery why she attracts beautiful girls. Perhaps that's Celine's personal charm. Sigh, it's really frustrating.

After giving Ekaterina a deep look, Sirin pulled her up from the ground, patted her clothes, and said, "Alright, wash up. You don't need to eat breakfast today. You're going to have surgery to stabilize the Herrscher core in your body. Don't worry, the surgery will definitely be successful."

"Surgery... Well... if the surgery is successful, can I stay here?" Ekaterina looked at Sirin nervously.

Upon hearing this, Sirin paused for a moment, then chuckled twice, pinched Ekaterina's cheek, and said, "Of course you can stay here. If you don't want to stay here, that's fine too. I can grant you your freedom. Although leaving a Herrscher body outside is a bit dangerous, I can guarantee your safety with my abilities and let you live a normal life. It's up to you to decide."

“I don’t need freedom, I just want to stay here!” Ekaterina said, her eyes seemingly shining.

After a moment of silence, Sirin didn't speak but instead gently patted Ekaterina's head.

"Let's go."

"Ah."

……

Möbius Laboratory - Operating Room

"Big sister, I'm coming in~"

'Click'

As the door opened, Sirin led Ekaterina into the operating room, and the moment she stepped inside, a scream rang out nearby.

"Aaaaaah!!!! No! Using this stuff will really break it!"

"Tsk tsk tsk~ Little guinea pig~ You still think you can escape? Cooperate with me in the experiment obediently, otherwise..."

"I...I understand...I will cooperate..."

Hearing these conversations, Sirin looked toward the source of the sound in confusion, only to see Isa trembling and hiding in a corner, while Mebius was slowly approaching Isa with two clips in his hand.

"It's okay, it will only hurt for a moment. The voltage is safe, nothing will happen."

As he spoke, Mebius clipped the clip onto Isa.

"Sister... what are you doing?" Sirin led Ekaterina toward Möbius. She had wondered why she hadn't seen Isa this morning; it turned out that Möbius had brought her to the operating room.

Upon hearing Celine's voice, Mebius stopped what she was doing and turned around. She had been so engrossed in her work that she hadn't even noticed Celine coming in.

"Cilin, why didn't you say you were coming? You almost startled me."

"I did hit it, but I did it outside the door. But... what are you doing, sister?" Sirin looked curiously at the clips on Isa's body.

"I'm planning to have her cooperate with me in an experiment. This is the experiment I came up with last night. I want to see if it can have any effect on a Herrscher or a pseudo-Herrscher when it's powered on. I tested the voltage before, and it's safe. It's just that this little guy isn't very cooperative with me."

“Power on…power on? Ah…” Sirin looked at Mebius in surprise. What strange idea had her good sister come up with this time?

Sirin glanced at Isa, who was huddled in the corner, with a look of pity on her face. However, she did not intend to stop it. After all, electricity was not a big deal for a Herrscher, even high voltage. It would just cause some injury. Even high voltage could not cause any harm, let alone safe voltage. It might just make her feel a little uncomfortable.

Just as Sirin was thinking this, Möbius suddenly said to her, "Sirin, since you're here, why don't you participate in this experiment too?"

"Eh...Eh???" Sirin stared wide-eyed at Mebius with a blank expression.

Chapter 164 Placement Play

"This... let's forget about this... it's not good, not good." Sirin couldn't help but take a half step back. Although being electrified wouldn't cause her any harm, and she could even use Honkai energy to greatly reduce the current entering her body, if Mebius were to conduct experiments on her, he would definitely increase the current output, and it would be 100% high voltage.

Because she is a Herrscher, too little current obviously wouldn't stimulate Sirin at all, and she might not even feel anything, so high voltage is needed.

While the high voltage wouldn't harm Sirin, it would still hurt. No one wants to experience pain, except for masochists, of course.

"Give it a try. With your strength, this little current won't hurt you at all." Mebius smiled and walked towards Sirin, leaving Isa behind, while Sirin retreated repeatedly.

“Sister, although I won’t get hurt, I can still feel things… I think it’s better to let Isa do this kind of experiment.” Sirin tried to divert Möbius’s attention back to Isa.

When Isa heard what Celine said, she stiffened and tensed up, fearing that Mebius would really turn his attention to her as Celine wanted. Although she was going to die sooner or later, she could delay it as long as possible.

However, Isa quickly calmed down and stopped being nervous, because Mebius hadn't listened to Sirin at all, and was instead moving closer to her.

Seeing this, Ekaterina felt a mix of emotions. After thinking for a long time, she made a choice: she closed her eyes and covered her ears to avoid seeing or hearing anything.

But even as she did this, a tidal wave of subtle sounds rushed toward her.

"Big sister... please don't do this..."

"It's okay... relax, it won't hurt. You're my sister, I'll be very gentle..."

"Big sister..."

These subtle sounds made Ekaterina even more uneasy, and finally she gave up and lowered her hand, opening her eyes.

At this moment, Celine had already been half-heartedly pulled into Möbius's arms, and she really couldn't refuse Möbius's request.

The experiment began quickly, but it was less of an experiment and more of a public display of affection. Möbius had Celine lie on the operating table and then enthusiastically clipped metal clamps onto her. Sometimes, when he touched something strange, Celine would make embarrassing noises, and Möbius would occasionally tease her. The two didn't seem to be conducting an experiment; rather, they looked like a couple engaging in some odd playful antics.

After obtaining Sirin, Isa was like a discarded lab rat, tossed aside by Mebius. She was still wearing clips, but she dared not remove them. In her slight torment, she even had the strange idea of ​​urging Mebius to experiment on her as soon as possible.

Time slowly passed. Although it was high-voltage electricity, it only made Sirin feel a little numb. The electrical energy was even directly converted by the Herrscher core in Sirin's body. However, these currents did increase the sensitivity of Sirin's body a lot.

Even after the experiment ended and Möbius removed the clamps from Celine, the side effect of increased sensitivity did not disappear. Celine's legs were so weak when she stepped off the operating table that she had no strength left.

"Big sister, my legs are a little weak, can you help me?" As she spoke, Sirin reached out her hand to Mebius, and Mebius did not refuse. Instead, he grabbed Sirin's wrist and pulled her towards him, letting her lean against his chest.

This whole operation left Ekaterina stunned, unsure whether to watch or not. At the same time, a variety of strange emotions welled up inside her, such as envy.

If only she could pull Sirin into her arms like that and tease the shy Sirin, how wonderful that would be. Thinking of this, Ekaterina felt a pang of disappointment. She knew it was impossible; she had lost from the very beginning.

Without a deep emotional foundation, and without the naturally gifted Tuantuan, there's no way she could win. Touching her own underdeveloped Tuantuan, Yekaterina sighed helplessly.

Just as Ekaterina was lost in thought, Sirin's voice brought her back to reality.

"Sister, Ekaterina is still watching. By the way, sister, didn't you say that Ekaterina would have the surgery today? You haven't forgotten, have you?"

Ekaterina was initially pleased to hear Sirin call her name, but when she realized Sirin wasn't talking to her, she felt a little disappointed.

Oh, so they weren't calling her after all. Although disappointed, Ekaterina still listened attentively to Sirin and Möbius's conversation.
