So what if I have a few billion concubines while I'm cultivating immortality?

As dawn broke, Qin Xiao sat cross-legged in the quiet room behind the Zichen Palace.

The joy of the six women successfully establishing their foundations is still fresh in my mind.

But one's own strength is the guarantee of everything.

The Nascent Soul Realm is a watershed moment for cultivators!

His cultivation at the late stage of Core Formation was like water about to overflow, just one step away from completion.

However, this kick requires thorough preparation.

"My natal magic weapon..."

Qin Xiao murmured, a sharp glint flashing in his eyes.

Once a cultivator reaches the Core Formation stage, they can refine their own natal magic weapon.

Magical artifacts are connected to their owners' hearts and souls, possessing power far exceeding that of ordinary magical tools, and can even grow as their owners' cultivation levels increase.

He had been busy instructing the women in their cultivation, handling state affairs, and dealing with matters in Jiangnan, and had not yet taken on this matter.

Now, the time has come.

"A natal magic weapon must be compatible with one's own cultivation method. The 'Hehuan Immortal Scripture' is based on the harmony of Yin and Yang and the mutual assistance of dual cultivation, and magic weapons should also follow this path..."

Qin Xiao closed his eyes and deduced, countless shapes flashing through his mind.

Sword, cauldron, bell, mirror, tower...

Ultimately, the design settled on a rare shape: a yin-yang harmony ring.

This weapon consists of two rings, one for yin and one for yang, which can be separated or combined, and are effective in both offense and defense.

It further aligns with the concept of the harmony of Yin and Yang, complementing the "Hehuan Immortal Scripture".

If successfully refined, it will greatly increase combat power.

It can further enhance the efficiency of spiritual energy fusion during dual cultivation, which is beneficial to both him and his Daoist partner.

Having made up his mind, Qin Xiao no longer hesitated.

He rose and walked towards the specially designated weapon-refining room. This room was adjacent to the alchemy room, and in the center stood the newly crafted weapon-refining cauldron.

The cauldron is taller than before, with intricate patterns and a faint glow.

With a wave of his hand, Qin Xiao summoned more than ten kinds of main and auxiliary materials that floated in front of him.

For three days and three nights, without sleep or rest.

All the materials were finally refined, transforming into various colored liquids, powders, and crystals, which floated in the air.

The most crucial step is the integration and shaping process.

Qin Xiao's expression was solemn, and his spiritual power flowed like silk threads, guiding all the materials into the cauldron.

"Buzz!"

The refining cauldron emitted a deep rumble, and the patterns on its body lit up one after another, shining brightly.

Qin Xiao sat cross-legged in front of the cauldron, his eyes slightly closed, his entire mind connected with the inside of the cauldron.

"Yin and Yang in harmony, water and fire in fusion..."

Qin Xiao silently recited the harmonization techniques recorded in "An Introduction to Weapon Refining".

One hour, two hours...

For two consecutive days.

Inside the cauldron, a ball of liquid the size of a human head, constantly shifting between gold and silver, slowly rotated.

Faint shadowy figures of dragons and phoenixes could be seen moving about within, exuding the charm of Yin and Yang.

"Shaping!"

The liquid responded to the sound and split in two, turning into two clumps.

A ball of intense heat and power, pale gold in color.

A soft, supple, and yin-like mass, in the color of moonlight silver.

The two clumps of liquid twisted in the air and gradually condensed into a ring.

The yang ring is slightly wider and thicker, with sun patterns engraved on its body.

The inner ring is delicate and exquisite, with moon and cloud patterns carved on its body.

The moment the double rings took shape, the spiritual energy in the room surged wildly and was completely absorbed into the rings!

"Buzz!"

"Clang!"

The clear, resonant sound echoed throughout the quiet room.

A burst of golden and silver light shot into the sky, which would have alarmed the entire palace had it not been for the protective array.

Qin Xiao bit his tongue, spitting out a mouthful of his heart's essence blood, which split into two streams and disappeared into the twin rings.

As the essence and blood entered the rings, the two rings trembled violently, their brilliance subsided, and they transformed into two simple gold and silver rings, which fell into Qin Xiao's palm.

The touch is both warm and slightly cool, evoking a feeling of connection.

[Ding! Detected that the host has successfully crafted the natal magic weapon 'Yin Yang Harmony Ring,' meeting the system reward requirements.]

[Distributing crafting gift packs...]

[Congratulations, host, you have obtained: Marrow Cleansing Pill x1]

[Marrow Cleansing Pill: Can improve the quality of spiritual roots and cleanse the physical body of impurities.]

[The effect is best when taken internally within the time it takes to burn an incense stick.]

Qin Xiao now held a pill the size of a longan with faint red patterns in his hand.

The fragrance is delicate and refreshing, invigorating the mind and spirit.

"Marrow Cleansing Pill, to improve the quality of spiritual roots?"

A hint of joy flashed in Qin Xiao's eyes.

He originally had dual gold and fire spiritual roots, but his aptitude wasn't top-tier.

If it can be improved, it will become a Heavenly Spiritual Root!

Without the slightest hesitation, he immediately put the Marrow Cleansing Pill into his mouth.

The pill melted instantly upon entering the mouth, transforming into a cool sensation that spread throughout the body!

"Um……"

Qin Xiao grunted.

I felt that my meridians, bones, flesh and blood, and even my dantian were being reshaped!

Wherever the medicine goes, it's as if countless tiny brushes are removing the fine impurities attached to the meridian walls.

The bones cracked and sprang, becoming even denser.

Flesh and blood wriggled and regenerated, expelling specks of grayish-black filth...

The most dramatic changes occur in the dantian.

The golden pill, gleaming with golden light, began to develop faint multicolored patterns on its surface under the influence of the medicinal power!

Gold, cyan, blue, red, and yellow.

The colors of the five elements flashed in turn.

Qin Xiao looked inward at himself, and his heart sank.

"The Five Elements? A mixed spiritual root?!"

He clearly remembered that the description of the Marrow Cleansing Pill was to "improve the quality of spiritual roots".

But the current situation clearly shows that he has changed from having two spiritual roots to having a mixed spiritual root with all five elements: metal, wood, water, fire, and earth!

Having a mixed spiritual root means that one’s spiritual energy attributes are mixed, making cultivation speed much slower than before, and breaking through bottlenecks several times more difficult!

"System, what's going on?"

Qin Xiao asked anxiously.

[Ding! Host's spiritual root mutation detected...]

[It is not a mixed spiritual root of the five elements, but a 'primordial pure Yang five elements body'.]

[A person with a naturally pure Yang Five Elements body possesses all five elements, but not in a mixed way; rather, the five elements are perfectly balanced and form a self-contained cycle.]

This physique's sensitivity to the spiritual energy of heaven and earth far surpasses that of a celestial spiritual root, allowing it to harmonize the five elements on its own, thus increasing cultivation speed by more than three times.

[It can also activate the five elements' spiritual power to nourish living beings, especially promoting the growth of spiritual plants.]

[The effects are greatly enhanced when a person with a pure Yang body cultivates with their Daoist partner.]

A series of prompts stunned Qin Xiao.

A naturally pure Yang Five Elements body?

The Five Elements in Perfect Harmony?

Increased cultivation speed?

Enhanced dual cultivation effects?

Qin Xiao then focused his mind and looked inward.

As expected, the Golden Core itself did not dim due to the increase in attributes; on the contrary, it became more radiant and solid.

With a slight thought, I tried to absorb the spiritual energy of heaven and earth.

The originally sparse spiritual energy in the quiet room now surged towards him like swallows returning to their nests, at a speed far exceeding that of before!

Even more miraculously, regardless of the type of spiritual energy, once it enters the body, it is naturally harmonized by the Five Elements cycle, transforming into pure Five Elements spiritual power, which then merges into the Golden Core without any hindrance.

"really……"

Qin Xiao opened his eyes, a fleeting, multicolored light flashing within them.

He raised his hand, and golden light, green mist, blue light, crimson flame, and yellow halo flashed from his fingertips in turn.

The spiritual power of the five elements moves at will.

"The Five Elements are perfectly balanced, endlessly regenerating; this innate pure Yang Five Elements Body is truly formidable!"

What moved Qin Xiao even more was the ability to "use the five elements' spiritual power to nourish living beings".

If it can truly promote the growth of spiritual plants, cultivating high-grade spiritual herbs will no longer be difficult in the future, and alchemy resources will be greatly abundant!

There's also an enhancement to dual cultivation effects...

For him, whose main cultivation method was the "Hehuan Immortal Scripture," this was undoubtedly a timely help.

"The most urgent task is to familiarize myself with this new physique and stabilize my cultivation."

"Then you can try to form your Nascent Soul!"
