290: Chapter 291 Refining the Taiyi Dao Seed!

Back at the market, Lu Shiyin had already begun the preliminary familiarization and sacrificial refining of that Spiritual Artifact.

Every day, she nourished the bottle's body with her own spiritual power, attempting to establish a connection with the spirituality within and sensing its internal structure and the patterns of spiritual power circulation.

However—

After all, it was a Spiritual Artifact paired with a Heaven-grade Cultivation Method; refining it was far beyond what ordinary Magical Artifacts could compare to.

The "taiyi heavy water" Origin contained within the pure water bottle was extremely overbearing, placing exceptionally high demands on the refiner's spiritual power purity and Divine Sense strength.

Although Lu Shiyin had outstanding talent and a solid cultivation base, relying on her strength alone to completely refine this Spiritual Artifact would take at least half a year to a year.

Moreover, there were several key bottlenecks within it that required external assistance to successfully break through.

After carefully studying the structure of the pure water bottle and the refining Mind-Cultivation Technique of the Taiyi Heavy Water Art, Ye Changge had a plan in mind.

What he thought was—

First, use the Yin Yang Creation Art to condense a "Taiyi Dao Seed."

This Dao Seed contained the purest Origin power from his Yin-Yang Dao Foundation, as well as the Great Dao aura that shared the same source and roots as the "taiyi heavy water."

Then, using this Dao Seed as a guide, he would help Lu Shiyin refine the pure water bottle.

In this way, not only could the refining time be greatly shortened, but the compatibility between the Spiritual Artifact and Lu Shiyin could also be improved, and perhaps... it might even allow the pure water bottle's rank to advance further.

Ye Changge told Lu Shiyin his thoughts.

After listening, Lu Shiyin's beautiful eyes were full of trust and dependence as she whispered:

"Whatever my husband says to do, your wife shall do."

Ye Changge nodded, and the two of them began refining the natal Spiritual Artifact in that Immortal Cave filled with Restrictions.

—

Inside the Immortal Cave, Spiritual Qi was dense, and Restrictions were layered.

Ye Changge and Lu Shiyin sat facing each other, with the jade-white pure water bottle suspended between them.

The body of the bottle rotated slowly, emitting a soft water-blue light that illuminated their faces, making them look dreamlike.

Ye Changge took a deep breath, and the Yin Yang Creation Art within his body surged into operation.

Majestic Yin-Yang Qi surged out from his Dantian, galloping through his Meridians before finally gathering in the palms of his hands.

He formed hand seals, palms facing each other, as a ball of light blending black and white slowly condensed between his hands.

The light ball was initially only the size of a fist, but as spiritual power was continuously poured in, it gradually expanded and solidified, eventually transforming into a thumb-sized bead with black and white colors flowing through it.

On the surface of the bead, patterns of Yin-Yang fish faintly emerged, rotating slowly and emitting a profound and mysterious aura.

This was—the Taiyi Dao Seed.

Fine beads of sweat broke out on Ye Changge's forehead, and his face turned slightly pale.

Condensing this Dao Seed consumed nearly thirty percent of his Origin power; even with his Foundation Establishment Second Layer cultivation and the Foundation of a perfect dao foundation, it was somewhat taxing.

But he did not stop.

He pushed his palms forward through the air, and the Taiyi Dao Seed slowly floated toward Lu Shiyin, hovering in front of the space between her eyebrows.

"Shiyin, focus your mind and calm your breath. Use your Divine Sense to guide the Dao Seed into your body."

Ye Changge's voice was steady, each word reaching Lu Shiyin's ears.

Lu Shiyin closed her eyes and extended her Divine Sense, carefully wrapping it around the Taiyi Dao Seed and slowly guiding it into her body.

The moment the Dao Seed entered her body, her frame trembled slightly.

A warm and majestic power surged in from between her eyebrows, slowly spreading along her Meridians. Wherever it passed, her spiritual power seemed to be activated, becoming lively and agile.

Ye Changge did not stop; he formed seals with his hands again, transferring streams of pure spiritual power into Lu Shiyin's body to help her guide and refine the Dao Seed.

At the same time, he split off a wisp of Divine Sense and probed into the pure water bottle, carefully sensing its internal structure and spiritual power circulation patterns to prepare for the subsequent refining.

Time passed quietly as the two of them focused on their cultivation.

—

One month later.

Inside the Immortal Cave, Ye Changge slowly exhaled a breath of turbid air.

One month later.

Inside the Immortal Cave, Ye Changge slowly exhaled a breath of turbid air.

He opened his eyes and performed internal inspection.

Within his Dantian, that magnificent Yin-Yang Dao Foundation remained as steady as a mountain, with black and white Qi circulating endlessly and emitting a heart-palpitating pressure. However, to one side of the Dao Foundation, the originally abundant Origin power was noticeably thinner, as if a large portion of it had been drawn away by something.

And beside the Dao Foundation, there quietly floated a—

golden bean.

Semi-liquid and semi-solid, it was exquisitely translucent and about the size of a soybean, with a warm golden light flowing throughout.

The light was not dazzling but rather soft as water, like a piece of solidified amber or a jade nectar that had not yet fully formed. Fine patterns faintly emerged on the surface, like natural runes, flickering as it slowly rotated.

This was—the Taiyi Dao Seed.

The core Secret Art recorded in the Taiyi Heavy Water Art, a "Seed of the Dao" condensed using the Cultivator's own Origin as a guide.

It appeared unremarkable, no larger than a soybean, yet it contained extremely pure "taiyi heavy water" Origin power. If implanted into a Cultivator's body, it would be like sowing a spiritual seed in barren land; in time, it would take root, sprout, and grow into a towering tree.

Condensing this Dao Seed was truly no easy task.

Ye Changge sighed softly.

For this past month, he had gone almost without sleep or rest, every day using the Yin Yang Creation Art to extract his own Origin, then using the methods of the Taiyi Heavy Water Art to condense, compress, and purify it.

That process was like slowly gouging out marrow from his own body and forging it into a miniature "Golden Core."

Every condensation was accompanied by intense consumption and exhaustion. The feeling of Origin being drawn away was definitely not something an ordinary Cultivator could endure. Had it not been for his perfect dao foundation and a Foundation far deeper than his peers, he likely would have been unable to hold on long ago.

Even so, he had consumed nearly forty percent of his own Origin power.

At this moment, his Dao Foundation appeared noticeably "weak"—the circulation speed of the Yin-Yang Qi was thirty percent slower than before, and the originally dazzling light had dimmed significantly, like an oil lamp that had most of its oil drained, leaving only a weak flame flickering in the wind.

"To return to Peak condition, it will take at least four or five months," Ye Changge murmured to himself, calculating in his mind.

Four or five months was neither long nor short.

Under normal circumstances, he might have felt it was a pity. After all, cultivation was like rowing upstream; delaying for half a year meant half a year's progress lost.

However, Ye Changge felt that doing this was quite worthwhile.

The reason was simple—

If he didn't condense this Dao Seed, Lu Shiyin probably wouldn't be able to complete the refining of that Spiritual Artifact, the pure water bottle.

The pure water bottle was a Heaven-grade Spiritual Artifact paired with the Taiyi Heavy Water Art, and the "taiyi heavy water" Origin contained within it was extremely overbearing,

placing exceptionally high demands on the refiner's spiritual power purity and Divine Sense strength. Although Lu Shiyin had outstanding talent and a solid cultivation base,
