Mortal: Starting in a chaotic starry sea, I can upgrade everything.

He secluded himself in the stone chamber.

Jiang Yu took out a pill, which was pure white and lustrous, surrounded by a faint glow.

Looking at the upgraded Dust-Reducing Pill in my hand—no, it should be called the Supreme Dust-Reducing Pill or the Immaculate Dust-Reducing Pill—I felt a surge of excitement.

Jiang Yu swallowed it in one gulp. As soon as the pill entered his throat, it transformed into a stream of pure spiritual energy that flowed through his limbs and bones.

This pill is pure and immaculate, and its medicinal power sweeps throughout his body, slowly cleansing away the mortal impurities and residual impurities from his cultivation that have accumulated within him.

Washing away the dust is a long waiting process.

Jiang Yu closed his eyes and sat down to meditate peacefully.

Time passed quickly, a month, two months...

After more than half a year, Jiang Yu's worldly vanities were washed away, his mind became clear, and he was completely transformed.

"It's time to break through to the Core Formation stage."

He murmured softly, took out the top-grade Snow Spirit Water and Heavenly Fire Liquid that he had prepared beforehand, and swallowed them in one gulp.

Then, he silently began to circulate the Profound Yin Technique, and the spiritual energy within his body slowly flowed towards his dantian...

Outside the cave dwelling, under the pavilion corridor.

Two beautiful fairies, dressed in long red robes that accentuated their slender figures and graceful bearing, sat on the railing, their bare feet swaying back and forth.

"Yuan Yao, why are you suddenly wearing red?"

Yanli smiled knowingly and said jokingly.

Three months ago, both of them entered the Foundation Establishment stage. The powerful medicinal effects of the superior Foundation Establishment Pill allowed them to reach the peak of the early Foundation Establishment stage after their breakthrough.

"What's wrong? Can't I wear red clothes?"

Yuan Yao rolled her eyes at him, clearly knowing full well what he was asking.

I don't know what the young master was thinking, but he said he wanted to see her dancing in red when he came out of the pass next time.

I'm so embarrassed...

"Hmm... I think you should take the initiative with the young master." Yanli's nails traced her rounded chin as she pondered.

Yuan Yao murmured, "Take the initiative..."

"Yes, for example, asking about the Yin-Yang Harmony Formula, hehe, and... like this!"

As Yanli spoke, her eyes suddenly curved into a smile, and she reached out her small hand to Yuan Yao's slender waist, then pulled her into a tight embrace.

"Hey, what are you doing?"

"Haha, Yao'er, you've become even more beautiful since you reached Foundation Establishment! When your senior sister sees you, she's truly breathtaking!"

"Senior sister, you're always like this..."

The two beauties were entangled and pulled at each other, occasionally revealing glimpses of their cleavage.

If Jiang Yu saw this, he would only marvel at the deep sisterly bond and then join in.

Time flies, the years are like a shuttle.

Another two and a half years have passed, and three years have gone by since Jiang Yu went into seclusion.

On this day, a strange phenomenon suddenly occurred in a corner of the sacred mountain that had been silent for a long time!

The rosy clouds soared into the sky, and auspicious clouds streamed down.

Fiery red clouds swept across the sky, and the spiritual energy of heaven and earth surged wildly, transforming into visible, turbulent spiritual waves.

Throughout Tianxing City, many cultivators looked up, all startled by this strange phenomenon.

The source of that strange phenomenon was none other than the location of the forty-second level cave dwelling somewhere on the Holy Mountain!

"That's the Core Formation stage!"

"Someone has reached the Core Formation stage!"

Many people pointed and commented on the strange phenomenon, which wasn't too surprising.

After all, there are a large number of cultivators in Tianxing City, and there have always been one or two instances of Core Formation phenomena over the decades.

Inside a pavilion at Miaoyin Gate.

"Mother, look! Someone has formed their Golden Core!"

The purple-clad girl, newly embarking on her immortal journey, gazed into the distance at the strange phenomenon through her bright, large eyes.

"Good Ning'er, Mother saw it."

The beautiful woman in the purple dress walked gracefully to the eaves, smiled gently, and stroked the head of the ten-year-old girl.

As he spoke, he couldn't help but look towards the strange phenomenon in the distance, as well as the location of the forty-second level of the sacred mountain.

This Fellow Daoist Jiang has already achieved Core Formation in just three years... truly extraordinary.

…………

As the strange phenomena gradually disappeared, Jiang Yu secluded himself in his cave.

"Only after swallowing a golden pill can one know that one's fate is in one's own hands, not in the hands of heaven."

That year, Jiang Yu was fifty-four years old.

He exclaimed in admiration, his Core Formation stage power was immense, far surpassing that of the Foundation Establishment stage.

The top-grade Dust-Reducing Pill he consumed during this seclusion did not accelerate his Core Formation process.

On the contrary, the remaining pure medicinal power greatly increased his magical power until he reached the peak of the early stage of Core Formation.

This saved him two or three decades of arduous cultivation.

However, Jiang Yu did not immediately leave the pass.

It wasn't until two months after he formed his core that he successfully mastered the Transformation Technique.

"It's time to emerge from seclusion."

After Jiang Yu finished speaking calmly, his aura remained steadily at the early stage of Core Formation. He then got up, left the stone bed, and walked outside.

After all, he had just formed his core, and his magical power was only at the peak of the early stage of core formation. This would definitely arouse suspicion, so it was better to keep a low profile.

…………

"Congratulations, young master, on successfully forming your core. From now on, you have a promising path to immortality."

The scenery outside the pavilions and corridors of the cave is delightful.

Dressed in black, Jiang Yu leaned back in a rocking chair, holding a cup of tea, looking relaxed and carefree, everything about him natural and easygoing.

Before him, Yuan Yao and Yan Li, two beautiful figures in red, one in the dark and one in the light, radiated the most radiant smiles.

Three years have passed, and the two women have shed their naivety, becoming more elegant and charming, while still maintaining their tall and slender figures.

Her allure is innate; every frown and smile carries a captivating charm.

With two mature and beautiful maids like these, it would be difficult for them not to cultivate the Yin-Yang Harmony Technique.

As their master, Jiang Yu felt honored.

"Hmm, Li'er, Yao'er, your cultivation has reached the mid-Foundation Establishment stage. It seems you've worked hard these past three years."

"And the herb garden and the gold-eating beetles, you've taken very good care of them, I've seen it all."

Jiang Yu nodded and smiled, taking a sip of the tea.

Women are always more considerate, both in the mortal world and in the cultivation world.

I took the two women as maids on Kui Xing Island and entrusted them with managing my cave dwelling.

Looking back now, that decision was absolutely right.

"Young master, is there any reward?"

As soon as she finished speaking, Yanli walked up behind Jiang Yu in a delicate voice, placed her hands on his shoulders, and unconsciously began to massage them.

She has mastered the Yin-Yang Harmony Technique and really wants to cultivate it with the young master...

"You audacious little vixen, daring to demand benefits, but well..."

"Now that I have reached the Core Formation stage, I have no use for these magical artifacts, so I'll give them to you."

Jiang Yu gently closed his eyes, a look of comfort on his face.

He casually patted his storage bag and took out a small crimson-gold sword and a small dark-gold hammer, both of which were top-grade magical artifacts.

"Thank you, young master. Xiaoli likes it very much."

Yanli didn't act coy at all, and smiled as she put the small crimson-gold sword into her bosom.

"Yao'er too." Yuan Yao's eyes lit up with joy.

She had witnessed the power of this dark gold hammer when Jiang Yu first wielded it, and she was filled with envy.

Unexpectedly, the young master actually gave it to her.

Jiang Yu's lips curled into a smile, and then he moved his lips slightly to send a telepathic message to Yanli.

—There will be a special reward tonight, but don't tell Yuan Yao.

Then Yuan Yao also received a similar message.

Upon receiving the telepathic message, the two women exchanged a glance, their cheeks flushed, clearly having seen through Jiang Yu's scheme.

The young master is up to no good again; they won't fall for his tricks so easily.

But after practicing the Yin-Yang Harmony Technique, my body and mind are itching...

Seeing the two girls' timid and shy appearance, Jiang Yu felt even more delighted.

After calming himself down, he asked seriously, "During my three years of seclusion, has anything happened in the outside world?"

Upon hearing this, Yuan Yao regained her composure and stepped forward to reply softly, "Sect Master Zhou of the Miaoyin Sect visited a year ago, saying he wanted to return 100,000 spirit stones. Since you were in seclusion at the time, I accepted them on your behalf."

"There are also some messages sent by various forces and cultivators in Tianxing City after the young master formed his core."
