Honkai, But a Back Spirit Simulator

"...Looks like it's not needed after all." Mobius revealed a playful, mocking smile.

Then—

She turned and left this home without a trace of sentimentality.

"You were too impulsive, you idiot ghost."

Mobius walked out of the house, suddenly feeling an unprecedented sense of relief, and couldn't help but joke.

"I couldn't just watch you get beaten up," Liu Bai said, patting Mobius's head. "Besides, I've been putting up with him for months."

"..." Mobius's face flushed slightly upon hearing this. She raised her hand to brush away Liu Bai's hand, then turned to look in his direction.

"So, that question—Mr. Ghost, in the future, will you continue to accompany me?"

"...I'm behind you. You're looking in the wrong place. There's only an anthill in front of you."

Liu Bai's voice came eerily from Mobius's ear.

"Cough, cough!" Mobius cleared her throat awkwardly, then turned around.

"Just kidding, you were facing the right way."

The gentle male voice next to her ear instantly became incredibly irritating.

"But... spending a little more time with you isn't out of the question."

[Mobius Compatibility +100%]

[The girl's ninth birthday was the last one she spent at home—and on this day, the girl gained a new home]

[Mobius began to support herself. What would be hellishly difficult for an ordinary little girl was a piece of cake for Mobius. Soon, Mobius had saved enough money to support her studies and life.]

[Finally, in the year Mobius turned eighteen, she had already become a scientist with considerable achievements in the field of biology, but you know that this is far from Mobius's limit.]

[This day, Mobius's eighteenth birthday, is also the anniversary of her meeting you eighteen years ago and leaving home nine years ago. It is also the day Mobius comes of age.]

"...Adulthood."

Liu Bai couldn't help but murmur.

He had a feeling that today was the last day of this storyline.

Liu Bai turned his head to look at Mobius, who was observing data. Eighteen years had passed. The newborn baby girl, the little girl from twelve years ago, the young lady from nine years ago, had grown into a graceful beauty... even to the point of being overly developed.

He couldn't make fun of her figure anymore. In fact, Liu Bai would even be teased by Mobius in return.

"Record this set of data. Once it's recorded, everyone can leave work. We'll do the rest tomorrow."

Mobius instructed in a gentle tone.

"Understood." The others in the lab nodded. Although they were a little puzzled as to why they were leaving work early, Mobius had already established her authority with her abilities.

Moreover... leaving work early wasn't a bad thing.

It was just a set of data. Under the temptation of leaving work early, all the researchers completed the recording in just a few minutes, and then left in droves.

"Mr. Ghost, what do you want to eat tonight?"

After everyone else had left, Mobius asked casually while changing clothes.

"? I can't eat anything, and what's with that old married couple tone?"

"It doesn't matter, you can watch me eat."

Mobius revealed a somewhat charming smirk towards the air.

The eighteen-year-old Mobius still had a nasty personality.

"Speaking of which, do I look good changing clothes? How is it compared to when I was a kid?"

Mobius showed a seductive smile. She still remembered the times when Liu Bai said she had no chest or butt.

"Want to touch? That's fine too~"

Compared to the little flat chests of six and nine years old, the power of this smile and these words from the mature eighteen-year-old Mobius was tenfold.

Liu Bai couldn't take it anymore.

"Well, but thinking about it, it would be too unfair to make me cook my own birthday dinner. Let's eat out tonight."

Mobius, who had changed her clothes, subtly pursed her lips.

—Virgin ghost.

"Whatever you want, just don't drink too much. I don't want to have to carry you home."

Mobius's drinking habits were really worrying.

"What's wrong, are you in a bad mood?" Mobius seemed to notice Liu Bai's low spirits, and the smile on her face grew even more. "Don't worry, I'll create an artificial body that ghosts can use in the future—of course, by then you'll be mine."

Mobius had two dreams.

One was what she had told her father back then: the evolution of humanity.

The second was to give Liu Bai a body that he could move around in.

It could even be set up so that once someone goes in, they can't get out, and they'll obey any command from the creator.

—No, maybe I can just use my charm to conquer this guy directly.

"...I have a feeling you're thinking about something bad."

"Oh~?" Mobius raised her eyebrows slightly. "Looks like my idea of slicing up the ghost for research has been discovered."

—She would never admit that she wanted to make Liu Bai her own.

Chapter 9: Just a Temporary Farewell

"...Speaking of which, it's been nine years since we left that house."

Sitting in a private room at the hotel, Mobius opened a bottle of red wine for herself, watching the liquid pour into the glass, a rare look of reminiscence on her face.

"Time really flies. When I think back to that time now... well."

Mobius raised her glass, observing Liu Bai through the wine-red liquid.

"It's all just emptiness... Every year, I have to wonder if you're just a figment of my imagination."

"When you're lying in bed reaching for something to eat, do you think a dog gets it for you?" Liu Bai said rather irritably.

"If you don't mind, it could be," Mobius said, downing the red wine in her glass in one gulp, a hint of intoxication on her playful face.

"But... I guess I'm just afraid you'll suddenly disappear, right?"

The sudden directness caught Liu Bai slightly off guard.

"Mr. Ghost... you know, I've experienced 'loss' three times so far."

Mobius refilled her glass.

"The first time was when I lost sight of you as a blurry stick figure when I was six years old... My mind really went blank back then." Mobius rested her cheek on her hand, swirling the wine glass.

"That time? Oh, I remember clearly how a certain sharp-tongued little brat looked like she was about to cry, but still didn't mince her words."

"That's quite a nasty description," Mobius said, pouting in dissatisfaction. "Isn't it normal for an inexperienced little girl not to want to show weakness in front of someone she likes?"

Direct hit *2

"As for the second time... well, let's talk about it together with the third time. My parents, don't think I left so decisively back then, but I spent a long time making up my mind before that."

"I know."

"...Yeah, you're the person who knows me best in the world—maybe also the person who doesn't understand me at all."

Mobius drained her second glass of wine, then poured herself a third.

"After all, it's understandable that a girl in love doesn't want to expose her flaws in front of someone she likes, right?"

Third direct hit.

Liu Bai finally realized that something was off.

Mobius downed the third glass of wine as if taking revenge.

Mobius's face gradually flushed red.

"Mr. Ghost, your mood is very strange today—from the time I met you until now, this is the first time I've felt 'melancholy' from you when you're off work."

Fourth glass.

"To make you feel lost... can I guess that today is the last day?"

From Liu Bai's emotions alone, Mobius deduced the real result.

"...Yes."

"That's great." Mobius forced a smile. "It's so great that Mr. Ghost can feel melancholy about this."

Fifth glass

"...Is it a permanent farewell, or a temporary one?"

"Temporary."

Liu Bai said decisively.

He believed that he would see Mobius again.

"...That's great." This time, Mobius showed a genuine smile. "That's really great."

Mobius could accept a tomorrow without Liu Bai, but she could not accept a tomorrow where Liu Bai disappeared.

"At first, I wanted to pretend I didn't know anything and happily spend this birthday, but, that feeling... I think, if I don't get an answer, I'll really go crazy."

A trace of tears flashed in the eyes of the future "Snake."

"I will move forward with a stronger attitude." Mobius casually wiped away the tears from the corners of her eyes, and stretched lazily, her proud curves revealed without reservation.

Afterward, Mobius showed Liu Bai a familiar playful smile: "However, since it's the last day, I'll have to trouble Mr. Ghost to take care of me one more time. By the way, you can do anything you want to me~"

"?"

Looking at this reassuring smile, Liu Bai suddenly had an ominous premonition.

"Waiter! Bring up your strongest liquor!"

Liu Bai looked at Mobius, sprawled on the bed in a drunken stupor, muttering in her sleep, and a helpless expression crept across his face.

The clock on the wall gradually ticked towards midnight.

[Simulation complete. Mobius: Childhood cleared. Mobius Compatibility +100%]

The sleeping form of the green-haired milf gradually blurred before Liu Bai's eyes.

[Simulation Rating: S (Highest Rating - A place in a girl's heart is forever reserved for one person)]

[Final Compatibility: 262%]

A full doubling of the compatibility compared to the last time, of course, corresponding to eighteen years of companionship.

As for the number 262%... Liu Bai's actions caused a 3% deduction in compatibility at birth, otherwise it would have been a more pleasing 265%.

[You have gained 3 Skill Points]

[You may choose one of the following skills]

[1. Researcher Lv10 (You have embarked on the path of truth)]

[2. Biology Lv8 (You are a leading figure in the biological world)]

[3. Medicine Lv7 (You possess top-tier medical knowledge)]

[4. Honkai Studies Lv4 (You have glimpsed a corner of the Honkai)]

The options presented by Mobius, who had not yet joined the Moth Chasers to Fire and become one of the Flame-Chasers, were one fewer than Aponia's, but it was a pure scientist template.

However, for Liu Bai, these skills were somewhat lackluster.

More importantly, as a ghost, he had virtually no opportunity to conduct experiments, so although at first glance they were all practical abilities, their value to Liu Bai was not high.

After a moment's thought, Liu Bai decisively chose the highest-level skill Mobius possessed—Researcher Lv10.
