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

"Master, I was wrong."

"And do you know what you did wrong?"

"I didn’t come to see you as quickly as I should have, Master."

...

"Brother, I was wrong too."

"Tell me why."

"I came too late, and almost allowed you to fall into danger."

...

Night quietly fell. The house remained silent, the candlelight slowly burning, shedding a faint glow while dripping strings of quickly solidifying wax. The flickering flame illuminated the room, casting shadows over the two girls’ faces, one filled with regret, the other with a furrowed brow.

In previous simulations, Xu Xi had always operated alone. He was very curious about how the girls who had broken through with supreme power into the simulated world existed, and whether they could use their supreme abilities.

"Alright, Brother," Xu Moli pondered for a moment, carefully choosing her words to explain her situation. Wu Yingxue helped supplement the details. Soon, Xu Xi understood the current status of the five girls in this simulated world.

They did not appear in Heaven Mystics Realm with their true bodies, but rather through a strand of consciousness that had crossed endless time and space to follow Xu Xi. If needed, Xu Moli and Wu Yingxue could unleash their supreme powers and leave this simulated world at any time. However, they chose to stay, planning to explore the true nature of the life simulator together with Xu Xi.

"Brother’s reincarnation…" Xu Moli murmured. "It truly is extraordinary. This world doesn’t exist in the upstream of time, nor the downstream. It does not even belong to the present era. Cause and effect shift, reality and illusion intertwine." After a moment of thought, Xu Moli concluded, "If we stay longer in this world, I believe... we may uncover something."

She lifted her hand lightly, and a miniature projection of a world, flickering between existence and nothingness, appeared in the air. It was Heaven Mystics Realm, seen from the supreme perspective, a mixture of reality and illusion, like a blurry dream.

Xu Xi could roughly guess the reason. Reality existed because Heaven Mystics Realm truly existed. Illusion came from the life simulator's influence, altering the world's direction.

"The status of the supreme beings is far beyond mine," Xu Xi thought. "In exploring the essence of the simulator, with Moli and the others helping, I probably don’t need to do much myself." Suddenly, Xu Xi realized something.

He could lie down and relax?

[You successfully reunited with your younger sister and the princess.]

[This is your first time conducting a simulation together with others.]

[You feel emotional.]

[You find this experience very fascinating.]

[You have a hunch that this simulation in the fantasy side will be your easiest one yet.]

[With three red entries by your side and five supreme beings following you, you truly can't think of anything in Heaven Mystics Realm that could trouble you.]

[Destined Protagonist entry activating...]

[Your Child of Destiny Physique is evolving. Your comprehension grows even more terrifying. With a single breath, you break through to 7th stage Mystic Qi Realm.]

[You cultivate diligently.]

[Furthermore, you continuously receive gifts of spirit pills. Your cultivation realm improves slightly every day, and significantly every seven days.]

"Brother, I brought some spirit pills," Xu Moli said sweetly.

"Master, I also brought some precious materials," Wu Yingxue added warmly.

The younger sister and the princess were both enthusiastic. In Heaven Mystics Realm, their starting identities were very prestigious—either disciples of great sects or daughters of powerful families. They were never lacking in resources to enhance their strength.

Xu Xi accepted everything gladly. He was no stranger to relying on such resources; he did it with ease and peace of mind. However...

"Moli, Yingxue," Xu Xi looked at the mountain-like pile of spirit pills, hesitating for a moment. "Isn't this a bit too much?"

"How could it be, Master?"

"You’ve grown thin from hunger. You must eat more!" Wu Yingxue said seriously, and with a push of her palms, stuffed a large amount of nourishing materials into Xu Xi’s arms.

Whoosh—Xu Xi broke through again. Simply by absorbing the spilled spiritual energy from the materials, he advanced to the 8th stage Mystic Qi Realm.

"Just like that?" Xu Xi was full of doubt. With the combination of three red entries and the supreme beings feeding him, his cultivation breakthroughs had become as easy as eating and drinking.

[Your cultivation proceeds incredibly smoothly.]

[Breakthrough after breakthrough after breakthrough!]

[You break through repeatedly, like a reignited star, burning away your past decadence and forcefully smashing through new bottlenecks.]

[You achieve the Human Mystic Realm in an instant.]

Because of the dramatic transformation in his strength, the bone ring he carried finally broke its seal. As expected, the soul inside the ring was Sylvia.

The ring was a common external aid for protagonists in many novels, usually housing either an artifact spirit or the soul of an ancient expert to assist the protagonist by providing guidance and powerful techniques.

Naturally, as Sylvia broke free from the ring, she immediately offered Xu Xi a powerful cultivation technique suited for the fantasy world, along with supplementary skills in alchemy and artifact crafting.

"Thank you for your hard work, Sylvia," Xu Xi said gently. Although Xu Moli and Wu Yingxue had already brought him a wealth of techniques and precious knowledge from Heaven Mystics Realm, Xu Xi didn’t overlook the efforts of this brave soul. He smiled warmly and expressed his gratitude to Sylvia.

"Sylvia, are you feeling well now?" Xu Xi asked.

"Please don’t worry, Master Sorcerer. I am completely fine," the spirit body took on a real form. Sylvia stood in the sunlight, her green eyes sparkling brightly. It was clear that, as a supreme being, Sylvia was nothing like those useless old ring grandpas who could only show up after being rescued by the protagonist.

"Master Sorcerer, you seem a little unhappy?"

"No, Sylvia. I’m just... feeling a little emotional," Xu Xi said as he gently patted Sylvia’s platinum-colored hair. It was soft and silky to the touch.

This simulation was simply going too smoothly.

No setbacks.

No difficulties.

No undefeatable enemies.

His cultivation realm was growing at an unimaginable pace. His comprehension and fortune were unmatched under the heavens. And no matter what troubles arose, he had supreme beings standing behind him to catch him if he fell.

Even the exploration of the simulator’s secrets required little effort from him now.

In that fleeting moment, Xu Xi, who was used to tirelessly struggling through each simulation, felt an almost surreal sense of peace. It was so perfect that it almost didn’t feel real.

"Master Sorcerer, do you not like it this way?" Sylvia asked softly.

"I like it," Xu Xi replied with a smile, patting the brave soul's head again. "Come, Sylvia. Let's go."

The protagonist could not stay confined to one small place forever. Having now reached the Human Mystic Realm, Xu Xi was ready to leave Cangwu City and venture into other regions.

"Krisha and Ailei still haven’t arrived," Xu Xi thought. "This means they must not be near Cangwu City. If I want to find them, I must travel further. If I’m guessing correctly, they’ll likely appear in the later parts of the protagonist's storyline."

Xu Xi looked up at the sky. Sunlight spilled freely over his face, lighting up his gentle features.

Marriage annulment and the fallen genius—these were classic beginnings for a protagonist.

But this was only the beginning. Most of the time, there would always be follow-up events like auctions, martial competitions, saving beauties, and battles between good and evil. Therefore, Xu Xi guessed that the locations of the witch and the machine servant would appear later in the storyline.

[Due to your progress in strength]

[You decide to leave Cangwu City and officially explore Heaven Mystics Realm]

[Countless races stand tall, and various forces compete for dominance]

[This is truly a grand world, filled with dazzling immortal light and divine might that suppresses all. Many spirit bodies, holy bodies, and divine bodies embark on the path of domination, all aiming to reach the Emperor Realm and suppress their era]

[You feel nostalgic]

[You think the worldview of Heaven Mystics Realm is very similar to the fantasy web novels you read as a child, a proper passionate fantasy world]

[After some comparison and searching, you decide on two destinations]

[The Ancient Desolate Mountains and the major sects and sacred grounds]

[The former is filled with many ancient beasts, suitable for protagonist-style training grounds]

[The latter is the gathering place for human experts in the Eastern Desolation Region, offering a grand stage suitable for building the protagonist’s reputation]

[You plan steadily]

[Thinking about how to best utilize the three red entries]

[At the same time, you subconsciously think about the people around you, wondering how to take care of them]

[Even though, as supreme beings, they no longer need your care]

The fallen genius left Cangwu City. Following the protagonist’s path, he headed toward farther, more dangerous, and more chaotic lands. Along the way, Xu Xi constantly pondered how to increase his strength while ensuring the girls' safety. He was used to doing so. Used to taking everything upon himself in simulated worlds, worrying and planning for those around him. Seeking ways to save his sister. Walking through life alongside the witch. Leading the princess and the Army of Survival out of the Ten Thousand Great Mountains. Burning his soul for the machine servant. Shielding the brave one from the malice of world-destroying forces. Throughout the simulations, Xu Xi had staggered forward, rarely finding time to relax.

But this time, Xu Xi suddenly found that he seemed to have nothing to do. Instinctively, he wanted to arrange everything, but before he could, the three girls had already prepared everything.

"Brother’s reincarnation, let me observe and confirm it."

"Master’s daily needs, let me arrange them."

"Master Sorcerer’s safety, let me protect personally."

Xu Moli, Wu Yingxue, and Sylvia quickly divided the tasks among themselves.

"Wait, what about me?" Xu Xi asked.

"Master Sorcerer, all you need to do is rest well," said the platinum-haired noble girl seriously. "In the past, you always cared for us. Now, it's our turn to repay you."

His younger sister and the princess echoed the same sentiment, saying that Xu Xi had worked too hard before, always forgetting himself and thinking only of others. In this special fantasy simulation, they insisted that Xu Xi must take it easy.

"Come on, Master, just rest," Wu Yingxue said, and without giving him a chance to refuse, she pressed down on his shoulders and made him sit in her dragon horse carriage. She smiled brightly, her eyes sparkling mischievously, like she had finally fulfilled a dream. "This time, it’s not your turn to play the hero."

The moon hanging in the sky did not need to do anything. The empty surface of the water would naturally reflect its image, becoming full and alive instead of cold and still.

"Then... alright," Xu Xi hesitated for a moment, then agreed to the girls’ request.

In the days that followed, Xu Xi handed over all authority.

At first, it felt extremely awkward. He wasn’t used to being so relaxed and idle inside a simulation. But by observing the girls, Xu Xi realized something.

Whether it was his younger sister, the princess, or the brave one, they had all grown mature and reliable. In some areas, they were even better than Xu Xi himself, and there was no need to worry at all.

"A simulation where I don’t have to do anything..." Xu Xi thought. "Maybe it’s not so bad after all..."

As they traveled, Xu Xi sat inside the dragon horse carriage, holding a cup of fragrant tea, quietly watching the wild scenery fly past outside. Fierce beasts roamed. Strange creatures appeared. Heaven and earth changed colors. Mountains and seas collapsed.

Even for a Destined Protagonist, at the early stages of weakness, such a path would have been treacherous. But now, with three supreme beings paving the way and dragon horse beasts pulling the carriage, everything went smoothly.

Xu Xi really wanted to find something to do.

But no matter where he looked, the girls had arranged everything so perfectly that there was nothing for him to add.

"Gulp—"

"Gulp—"

He sipped the tea lightly, feeling the spiritual energy flowing through his meridians. Xu Xi circulated his technique, instantly refining the spiritual energy into a solid foundation for his cultivation.

"Perhaps Sylvia and the others are right. I should really take a good rest once in a while," Xu Xi thought. "Since I have the protagonist entries, it wouldn’t hurt to experience the treatment of a protagonist too."

[First month after leaving Cangwu City]

[Your reputation has spread far and wide]

[Several nearby human cities have all heard that the once-fallen Xu Xi was not humiliated by a broken engagement but instead became the son-in-law of the Wu family]

[For some reason, the news spread extremely fast]

[Almost half of the Eastern Desolation Region now knows about it]

[Wu Yingxue solemnly promised to capture the rumor-mongers, but half a month later, the rumors only spread more wildly]

[Some people feel resentful]

[They think a waste like you is not worthy of marrying into a martial arts family]

[One man, twisted by jealousy, blocked your convoy and insulted you, declaring that you had no right to marry Wu Yingxue]

"A woman should only belong to the strong!" the man shouted arrogantly, demanding a duel with Xu Xi.

Xu Xi did not respond verbally. He simply stirred his vast spiritual sense, drew upon his surging blood energy, and slashed out a distant hand strike.

In an instant, the void trembled, thunder rumbled, and the distant earth cracked open.

"W-What?!"

"Earth Mystic Realm!"

"This boy is terrifying beyond words!"

Countless people gasped in shock, perfectly playing their part.

[Second month after leaving Cangwu City]

[Because of your decisive action, people's discussions about you have changed. They no longer call you a waste but a reborn genius]

[Someone exclaimed: Wu family's son-in-law, terrifying beyond imagination!]

[The marriage rumors spread even more fiercely. No matter how hard Wu Yingxue tried to suppress them, she could not stop the tide]

[You comforted Wu Yingxue with a gentle voice, telling her not to blame herself]

[Third month after leaving Cangwu City]

[You passed through a human city hosting an auction]

[Destined Protagonist activating... From Despair to Prosperity activating...]

[You chose to participate in the auction and purchased a rusty bronze mirror at a low price. Many people laughed and shook their heads, thinking you were wasting money and pretending to understand antiques]

[You dripped your Child of Destiny blood onto the mirror]

[Congratulations! You have obtained the ancient treasure Heaven’s Secret Mirror and awakened the artifact spirit, Ailei]
