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

[You open your eyes and find the world before you shrouded in darkness.]

[The sky is dim, the land is desolate, scattered with bones and countless gravestones. You awaken in a mass grave, the only living being in sight.]

[You have no dog, no weapons, no supplies.]

[You start with nothing.]

[The only thing you possess is the healthy body of an 18-year-old—your sole asset for surviving in this foreign world.]

The night was pitch-black.

Even the moonlight was cut off.

Gravestones stood tall, human bones lay askew, and the eerie wind howled like grinding teeth, piercing through the air.

When Xu Xi opened his eyes, this was the sight that greeted him.

Crunch—

Crunch—

With every step he took across the mass grave, something shattered beneath his feet, producing crisp cracking sounds and fragments scattering further.

“Well…”

“This is exactly what I expected from the Necromancy Side, huh?”

“A gloomy start, dumping me right in the middle of a graveyard.”

The night was thick and heavy.

The wind whistled through the air.

A suffocating deathly aura loomed over the sky, blocking out all celestial bodies, erasing the distinction between day and night.

People feared such a world, yet they were powerless against it.

This was the world’s law, a disaster beyond human control.

The only thing they could do—

Was accept it. Adapt to it.

Suddenly, a violent storm raged across the land, sweeping everything into the air. For a brief moment, it scattered the deathly mist, revealing a blood-red moon hanging ominously in the sky.

Xu Xi saw it.

A colossal skeletal form, its bones massive and unyielding, soared through the sky with wings as wide as sails.

Within the hollow sockets of its dragon skull, a deep blue soul flame flickered, casting an eerie glow.

It was an undead dragon, a creature standing at the pinnacle of the undead hierarchy.

Even without flesh and blood, with only a skeletal frame remaining, the dragon still ruled the skies, carrying a hazy figure upon its back, soaring toward the distant horizon at incredible speed.

Wherever it passed—

People trembled in fear, chanting praises to death’s supremacy, terrified of the bone dragon’s overwhelming power.

Yet amidst their fear, there was also envy.

If given the chance, they too wished to be that powerful.

“Necromancers, huh…”

“A transcendent system built upon souls, seeking the truth of the world.”

“Before starting the simulation, I memorized several soul-cultivation techniques used by necromancers. But right now, the priority is finding a safe place to stay.”

Xu Xi glanced at his surroundings.

The bleak landscape of the mass grave made him sigh in resignation.

He had no intention of staying here any longer.

Fortunately—

After undergoing multiple simulations, he was already accustomed to such grim starting scenarios.

“A new life… begins now.”

[Your adaptability is exceptional.]

[You quickly integrate into a nearby human village.]

[By gathering information, you learn some basic knowledge.]

[This world was once a paradise for the living.]

[It was home to intelligent races such as humans, elves, goblins, dragons, and beastmen.]

[However, a thousand years ago, an evil necromancer established contact with the Abyss of the Underworld—a realm where all dead souls reside, the final resting place for wandering spirits.]

[Due to this, the fragile world was gradually corrupted by the Underworld, transforming into what it is today—a twisted, chaotic existence where undead calamities erupt from time to time, wiping out entire kingdoms.]

[The living and the dead coexist. History and laws have been rewritten.]

[The deceased can no longer find peace. Everyone now exists within an eternal darkness.]

[Only the necromancers, standing high above, can study and wield the power of souls, allowing them to thrive in this dark world, unafraid of death’s grasp.]

…

[Not everyone can become a necromancer.]

[Just like any transcendent system, there are limitations such as talent and comprehension.]

[Only those with powerful souls are qualified to embark on the path of necromancy, starting from the weakest apprentice and ascending step by step.]

[You smile—your soul is incredibly unique, making you a born necromancer.]

[You formulate a development strategy.]

[Fortify your defenses, stockpile resources, and bide your time before making a move.]

[Interacting with other necromancers or exploring deeper necromantic knowledge is not your immediate priority.]

[You decide to remain in the nearby human village and use the soul-cultivation techniques you brought from the real world to first advance to an apprentice necromancer. Only after gaining some strength will you consider other options.]

Six months later—

In an unremarkable human village, on the isolated outskirts—

Xu Xi sat cross-legged in silence, surrounded by scattered objects.

There were undead bones scavenged from the mass grave, along with coarse emergency rations.

The environment was filthy, emitting an unbearable stench.

But since he planned to leave soon, he didn’t care much about it.

“Tsk…”

“When I build my own necromancer tower, the first thing I’ll do is set up an automatic cleaning spell.”

“But for now, I should focus on advancing to an apprentice necromancer first.”

Muttering to himself, Xu Xi grabbed a piece of rough black bread and forced himself to chew through the tough texture, easing the hunger gnawing at his stomach.

Then, he activated the necromantic cultivation technique.

His soul and spirit resonated.

Life and death intertwined.

Wisps of ghostly blue soul fire emerged from the pile of skeletons in the room, dissipating into the air, fueling his advancement.

Compared to the bone dragon he had seen before, these soul flames were minuscule.

They wouldn’t help much.

But Xu Xi was special.

With the Cycle of Life and Death trait, even these tiny traces of soul fire were enough for him to become an apprentice necromancer.

A breakthrough—instantly achieved!

…

[You have become an apprentice necromancer.]

[Though you’ve just broken through and lack accumulated time and knowledge, your soul has already begun to transform, making you fundamentally different from ordinary people.]

[You start learning apprentice-level spells.]

[Most newly advanced apprentices can only master one or two spells, but due to your exceptional talent, your limit is directly raised to twenty.]

[You work hard, dedicating yourself to meditation and engraving multiple apprentice-level spell structures into your soul.]

[You have successfully gained the ability to protect yourself.]

[From today onward, you no longer need to sneak up behind skeleton soldiers and bash their skulls in with a wooden stick.]

[Now that you have become a noble spellcaster, you can choose a more elegant method of execution.]

[Spells such as Acid Splash and Bone Fracture seem particularly suitable to you.]

[You leave the human village where you lived for the past six months.]

[This area is remote, safe from large-scale undead calamities. However, it also lacks the necessary resources for a necromancer to grow, making it unsuitable for long-term research.]

[As you journey forward, searching for a larger human city, you encounter various undead creatures.]

[Ding—]

[You have slain a skeleton soldier. Soul Collector effect triggered. A portion of the dissipating soul fire has been absorbed as your own power. You have grown stronger.]

Xu Xi traveled steadily, cultivating while testing his trait effects.

The Cycle of Life and Death trait granted him exceptional necromancer talent and a unique perception of life and death.

The Thinker trait kept his mind calm and allowed him to analyze knowledge more efficiently.

And the Soul Collector trait—whether it was a living being or an undead, anything that perished by his hand would have a portion of its soul fire intercepted before reaching the Underworld.

It could be used for research.

Or to strengthen himself.

“What kind of messed-up world is this?” Xu Xi muttered.
