Yin-Yang Spiritual Fire is born!

That was a temptation stemming from the Origin of life, thousands of times stronger than the grand yin profound crystal beneath him.

"Chirp..."

It let out a tentative cry and carefully flew a little closer to Lin Yuan.

The smile at the corner of Lin Yuan's mouth deepened.

He began manipulating the Blue Fire Lotus in his palm, making all sorts of incredible transformations. Sometimes it turned into a Swimming Dragon, sometimes into a Flying Phoenix, and sometimes into a burning sharp sword. Every change displayed an ultimate understanding of fire, a dao rhyme of returning to simplicity.

This was no longer a Battle of Spells, but an act of "Imparting the Dao."

The Ice Flame Fire Bird was completely stunned. As a pure Elemental Creature, its perception of this Origin Dao was the most acute. It circled and danced around Lin Yuan, letting out cries of joy, like a believer who had found faith, or a fan who had met their idol.

Seeing that the time was right, the light of the Blue Fire Lotus in Lin Yuan's palm diminished, turning back into a small flame. He beckoned the Ice Flame Fire Bird with his finger.

The Ice Flame Fire Bird did not hesitate in the slightest. It cried out happily, transforming into a pale stream of light, and willingly flew into Lin Yuan's palm, affectionately rubbing against his fingers, finally turning into a strange half-white, half-blue Flame Mark, branded onto the back of his hand, completely submitting.

Success!

Lin Yuan smiled contentedly. Subduing this Heaven and Earth Spirit Fire was far better than shattering and reforging it. By preserving its spirituality, its future potential for growth was limitless.

Having dealt with the Profound Fiend Ice Flame, his gaze turned intensely toward the massive grand yin profound crystal.

He walked forward and reached out to touch it. An extremely frigid energy, capable of freezing the Soul, traveled up his fingertips. This item was not only Divine Material for refining Spell Cultivator Magical Artifacts, but also a supreme treasure sought after by Cultivators who practiced Yin-Cold Attribute Cultivation Techniques.

"Can't waste this."

Lin Yuan did not hold back. He immediately summoned the Six Harmonies Sword, activated his Magic Power, and began cutting. The grand yin profound crystal was incredibly hard, but under the sharp edge of the supreme grade Magical Artifact, he still managed to forcibly slice off a large chunk.

After thinking it over, he decided not to take the entire piece. It is wise to leave a thread of possibility for future encounters. Since this place could nurture the Profound Fiend Ice Flame and the grand yin profound crystal, perhaps other good things might grow here later.

Only after placing the enormous grand yin profound crystal into his Storage Pouch was he satisfied and prepared to leave.

When he surfaced from the pitch-black Deep Pool, bringing the newly subdued Profound Fiend Ice Flame with him.

The three women waiting anxiously on the shore saw that he was safe and sound, and that his harvest was so immense, that their beautiful eyes widened, their red lips slightly parted, and they were speechless for a long time.

Fu Qingxuan, in particular, looked at the strange Flame Mark on the back of Lin Yuan's hand, sensing the aura within it—both icy cold and docile—and her shock was beyond measure.

She had personally witnessed the power of that ice flame before.

How much time had passed? It had actually turned into a docile pet!

Aboard the Flying Boat, the atmosphere was completely different from when they arrived.

Yue Qingyao and Fu Qingxuan's gazes would drift, intentionally or unintentionally, toward the man who was resting with his eyes closed. Previously, their impression of Lin Yuan was mostly based on reverence for his strength and the grand vision of his Alliance concept. But after the trip to the Yin Fiend Mountain Range, a trace of almost blind admiration quietly mingled with that reverence.

That composure and dominance—treating Great Arrays as nothing and subduing Heaven and Earth Spirit Fire while chatting—had exceeded their understanding of what a "Strong Expert" was.

Ji Hanyou was even more obedient, serving tea and water to Lin Yuan, the dependence and reverence in her eyes practically overflowing.

Only Ye Youmeng was still leaning against the cushion, but in her captivating Peach Blossom Eyes, an intense, lingering affection had appeared.

Lin Yuan slowly opened his eyes, and the half-white, half-blue Flame Mark on the back of his hand flickered slightly.

After a period of Refinement, he had completely mastered the Profound Fiend Ice Flame. At this moment, the two Heaven and Earth Spirit Fires were inside his body, one on the left and one on the right, distinctly separated, yet subtly forming a marvelous balance.

"Yin and Yang generate each other, cold and heat intermingle—this is the true Dao," Lin Yuan suddenly spoke, looking at the three women. His voice was calm, yet seemed to contain profound truth. "A singular extreme eventually reaches its end. Only by embracing opposition can one achieve the infinite."

He was finding a "reasonable" explanation for his upcoming actions.

Sure enough, upon hearing this, Fu Qingxuan was struck as if by lightning. Her eyes shone, and she immediately sat cross-legged, falling into an Epiphany. She primarily Cultivated the Talisman Dao, which greatly emphasized Yin and Yang balance, so Lin Yuan's words were nothing short of Enlightenment from an Immortal for her.

Yue Qingyao was also deep in thought. The Ethereal Immortal Art she Cultivated focused on cold aloofness and detachment, but perhaps because of this, it lacked some of the "Yang Qi" of the Mortal World.

Seeing this, Lin Yuan nodded in satisfaction. As expected of educated people; a few random remarks were enough to leave them stunned.

He stopped speaking and started the main task.

Step one: Fire Fusion!

He spread his palm. A faint blue Earth Core Nether Fire rose from his left hand, scorching and dominant; a pale Profound Fiend Ice Flame rose from his right hand, cold and deathly silent.

The two completely opposing forces caused the air inside the Flying Boat to begin twisting.

"Alliance Leader, this... this is too dangerous!" Yue Qingyao couldn't help but exclaim. Water and fire are incompatible, Yin and Yang clash; if he made even a slight mistake, the two Heaven and Earth Spirit Fires would detonate on the Flying Boat, and everyone would be instantly vaporized.

"It's fine."

Lin Yuan's expression was calm. The Fire Control Technique at Ninth-Grade Perfection gave him absolute confidence.

Under the control of his Divine Sense, the two flames began to slowly approach each other. They instinctively repelled one another, emitting sizzling sounds of energy annihilation.

Lin Yuan's eyes narrowed. His powerful Divine Sense transformed into an invisible large hand, forcefully pressing them together. At the same time, he guided the flow of the two energies with an incredibly mysterious rhythm.

It was no longer confrontation, but intermingling.

He used the "heat" of the Earth Core Nether Fire to warm the "cold" of the Profound Fiend Ice Flame; and he used the "Yin" of the Profound Fiend Ice Flame to neutralize the "Yang" of the Earth Core Nether Fire.

This was an incredibly delicate process that demanded abnormally high levels of Divine Sense and control.

The two flames in his palm began to slowly rotate like the Taiji Dual Fish. The faint blue and the pale white chased and permeated each other, their boundaries gradually blurring.

Finally, amid a crisp buzzing sound, the two flames completely merged into one!

A brand new flame appeared in Lin Yuan's palm.

Its entire body displayed a deep Chaos color, and in the core of the flame, streams of black and white light seemed to slowly rotate. It no longer purely emitted heat or cold, but a more Origin-level, terrifying energy possessing the dual characteristics of annihilation and creation.

As the flame flickered, a friendly thought seemed to transmit from it, like a newborn infant filled with dependence on its father.

"From now on, you shall be called the 'Yin-Yang Spirit Fire'," Lin Yuan chuckled softly.

The power of this Yin-Yang Spirit Fire was several times stronger than when the two previous flames were used separately!
