Life Simulation: I Caused the Female Sword Immortal to Regret Forever

A misty haze lingered, dreamlike and ethereal, resembling fleeting light and hurried breezes. As the sun shifted angles, the cedar forest scenery changed accordingly, ripples spreading across the water, drawing one’s mind into the depths of the mysterious woodland.

Crunch.

Crunch.

The thick soles of their boots pressed against the dried leaves on the soil’s surface, producing crisp, clear sounds.

Xu Xi held Ailei’s hand, strolling through the tranquil autumn landscape. Their footsteps wove between the towering trees, treading over scattered pebbles, ascending a gentle slope, leaving behind a trail of deep and shallow footprints.

“Ailei, watch your step,” Xu Xi reminded her carefully.

Ailei instinctively nodded, tightening her grip on his warm hand.

As an AI, her sensors and cameras served as her “eyes.” Over the past decade, she had commanded countless battles, her mechanical forces sweeping across vast territories. Her knowledge and experience were no less than that of the Federal database.

But this time, it was different.

Her silver-blue eyes saw nothing else—only the intertwined hands and the warm, steady figure leading the way.

Through countless data analyses and logical calculations, Ailei vaguely understood the reason behind this trip.

Xu Xi brought her here out of care and consideration.

Yet, no matter how much she calculated, cold data could never fully comprehend the warmth of human emotions.

Her logic circuits repeatedly informed her that such activities were meaningless. Machines existed to serve and work, not to rest and take leisure walks like humans.

Confusion stirred within Ailei, emotions bubbling in her metallic frame and data-driven consciousness. A desire to understand humanity welled up inside her.

Finally, she voiced her uncertainty.

“Master… why are you doing this?”

Her soft question blended with the rustling wind, as uncertain as her delicate gaze.

“There’s no reason, Ailei,” Xu Xi responded with a gentle smile, just as he always did. “You’re not just a machine; you’re real, like a person.”

“And people should rest, not work endlessly.”

“…Master, you are truly strange,” Ailei replied.

How could anyone treat a machine, a construct of circuits and logic, as an equal?

And because her master was so strange, Ailei decided to protect him.

Without warning, she tightened her grip.

Xu Xi gasped in pain.

“Ailei… what are you doing?”

“Since Master is strange, it has made me strange as well,” she stated calmly. “Therefore, after careful calculation, I have concluded that Master must take responsibility for me.”

Without hesitation, Ailei wrapped her arms around his.

The chilling touch of her metallic body sent shivers down Xu Xi’s spine, and he involuntarily trembled several times.

…

[Ailei’s humanity is delicate and elusive.]

[To better guide her growth, you take her on trips whenever you rest from researching starship technology, using the beauty of nature and your words to nurture her humanity.]

[You believe these actions are effective.]

[Over time, Ailei has grown more human-like, but for some reason, you’ve been dreaming of Krissa more frequently.]

[You can’t help but wonder—is it because you miss the witch too much?]

…

[Simulation Year 13: You are now 32 years old, with Ailei by your side for 11 years.]

[Your research on starship technology has made significant progress, and you have successfully mastered the ship’s engine, enabling space travel.]

[Excited, you work tirelessly on further research.]

[After persistent effort and resonance with machine souls, you unlock the secrets of the starship’s external armor.]

[The long hours take their toll, and you decide it’s time for another trip. This time, you take Ailei to the endless ocean.]

[The sea is vast and teeming with marine life.]

[Lowering your anti-gravity skiff to the right height, you leisurely take out a fishing rod and begin fishing from the deck.]

“Master, are you fishing?”

“Of course.”

“Then why haven’t you caught a single fish?”

“…”

Silence was the best response.

Xu Xi believed it must be the strong waves today, interfering with his fishing skills.

He looked at the rolling blue waves and then at the empty bucket beside him, silently putting away the fishing rod.

“Master, are you giving up?” Ailei asked curiously.

“No, I suddenly have a new idea for an experiment,” Xu Xi said.

His loyal mechanical maid believed him.

[The trip ended in haste.]

[On the way back, the anti-gravity skiff accelerated too quickly, causing a massive wave to rise, flinging a fish high into the air.]

[You unexpectedly caught your first fish.]

…

[Simulation Year 14: You are now 33 years old, with Ailei accompanying you for 12 years.]

[Your research on starships is nearing completion.]

[With Ailei’s computational assistance, starship factories have been established across the planet, producing parts in an orderly fashion. In time, you will have an entire fleet.]

[This year, Ailei provided you with an upgraded second-generation gene enhancement serum.]

[After taking it, your vitality increased significantly, extending your lifespan even further.]

[Time and aging left no trace on your face, and you marveled at the power of technology.]

[Ailei expressed an inexplicable sense of victory.]

[You smiled, thinking it must be her thirst for knowledge satisfied by the breakthrough.]

[This year, you decided to visit the legendary flower fields of the old Federation.]

[Your loyal maid, as always, accompanied you.]

“This place… really lives up to its reputation as one of the Federation’s most famous attractions. It’s truly breathtaking.”

“Master, shall I transplant some flowers for you?”

“…No, let’s leave the flower fields as they are.”

Stretching endlessly before them was a breathtaking sea of flowers.

Brilliant and diverse blossoms swayed under the sunlight, forming gentle waves of color, rolling forward and retreating with the wind.

Amidst the vibrant landscape, Xu Xi and Ailei stood still, quietly admiring the rare beauty in this post-apocalyptic world.

Through the years, Ailei had never changed her body.

However, her evolving personality subtly altered her appearance.

The same actions, the same expressions—yet now, they held a trace of humanity.

She bent down gently, brushing her fingers over a deep blue flower resembling a butterfly.

“Master, this one… is beautiful,” Ailei said, sharing her delight.
