In the most yin place, ice and flames transform into a phoenix!

"The Dao follows nature, and so does a Formation," Lin Yuan's voice drifted over, carrying a hint of guidance. "Regarding breaking a Formation, the lowest level uses brute force, the middle level seeks its gate of life, and the highest level makes the Formation work for you. If it draws upon the Evil Qi of the earth veins, you become the earth veins; if it takes the Four Symbols as its exterior, you transcend the Five Elements. If it thinks it is the heavens, you must tell it what lies beyond the heavens."

As his words fell, he gently pushed with his fingertip, and that Void Realm Talisman dropped into the energy barrier ahead like a drop of ink into water, silently merging within.

There was no earth-shattering roar, nor any collision of dazzling spiritual light. The "Four Symbols Sky-Locking Formation," which was indestructible and capable of withstanding the fierce attacks of a Late Nascent Soul Stage Cultivator, simply rippled open before them like a docile curtain, creating an opening wide enough for several people to pass through.

Ye Youmeng's beautiful eyes sparkled with brilliance. She considered herself powerful, but faced with such a Formation, she could only choose the clumsiest method—using absolute power to blast it open.

Yet, Lin Yuan's nonchalant and effortless methods stirred an inexplicable palpitation in her heart.

Yue Qingyao was even more shaken. Watching Lin Yuan's back, the lingering resentment and unwillingness she had felt because her Sect was "invited" had already vanished into thin air.

She couldn't help but smile. Facing a person like this, even if the Misty Immortal Sect were a bit stronger, it would likely eventually submit. Perhaps... submitting to him was truly a broad path toward greater heights for the Sect.

"Let's go." Lin Yuan chuckled and was the first to step into the Formation.

Passing through the ripples, the scene before them suddenly opened up, yet it made one feel a chill from the bottom of their heart.

Outside the Formation were black mountain ranges filled with endless Evil Qi, but inside, it was a white world of ice sculptures and jade masonry.

The ground was covered with a thick layer of ice, not formed from water, but a product of Evil Qi condensed to the extreme. On the stone walls on both sides of the valley hung ferocious ice spikes, emitting a faint, cold light.

The air was filled with a strange energy—bone-chillingly cold, yet containing immense vitality, contradictory yet harmonious.

"What a Land of Extreme Yin." Ye Youmeng exclaimed in admiration. In this environment, the Myriad Poison power within her was actually somewhat excited.

"Master, the Profound Fiend Ice Flame is in the cold pool at the deepest part of the valley." Ji Hanyou pointed forward, her voice tinged with a trace of fear.

Everyone looked in the direction she pointed. At the end of the valley, there was a deep pool spanning a hundred zhang. The pool water was as black as ink, yet the surface steamed with wisps of white cold Qi.

In the very center of that cold pool, a pale white flame, about the size of a human head, which seemed to be able to freeze the Soul, was quietly hovering.

It lacked the scorching heat and violence of ordinary flames, possessing only an extreme stillness and coldness. The surrounding air seemed to have solidified because of its presence.

"Profound Fiend Ice Flame..." A flash of fervor crossed Lin Yuan's eyes.

His figure flickered as he flew toward the ice flame, reaching out with a claw from a distance, preparing to collect it.

The pale white flame shuddered violently. "Chirp!" A clear yet incredibly cold Phoenix cry rang through the valley!

The Profound Fiend Ice Flame suddenly unfurled, its form shifting. In an instant, it transformed into a magnificent Fire Bird with a wingspan of over ten zhang, entirely composed of pale white ice crystal flames!

It had gorgeous tail feathers like a Phoenix, yet they shimmered with a deadly cold light; it had eyes as sharp as a divine eagle, yet they burned with ice flames that could freeze everything.

It hovered in mid-air, noble and deadly. Its cold eyes locked onto Lin Yuan and his group, as if scrutinizing ants that had trespassed into its territory.

"Careful! It has intelligence!" Ye Youmeng cried out, her figure flickering as she blocked in front of Lin Yuan.

The Ice Flame Fire Bird was clearly enraged. It let out another sharp screech and flapped its wings, and the overwhelming pale flames swept over like a tsunami!

Wherever these flames passed, the space emitted "crackling" sounds of freezing, and even the light seemed to become sluggish.

Ye Youmeng dared not delay. She formed hand seals, and countless colorful poisonous lights erupted from her body, transforming into a brilliant poisonous net before her, attempting to block the pale flames.

However, a shocking scene occurred. The incredibly potent poison, which could melt anything, met its nemesis the moment it touched the pale flames. It rapidly lost its activity, freezing into colorful ice crystals that fell from the air with a clatter.

"Misty Sword Rain!" Seeing this, Yue Qingyao acted decisively. She pointed her jade finger, and the long sword behind her unsheathed, transforming into a sky full of sword shadows, carrying the cold power of moonlight, and slashed toward the Ice Flame Fire Bird.

But the moment those Sword Qi neared within three zhang of the Fire Bird, they rapidly condensed a layer of white frost. Their speed greatly decreased, and their power was weakened by more than seventy percent, ultimately only leaving a few shallow white marks on the Fire Bird's ice crystal wings.

"This thing is immune to most Spell attacks!" Fu Qingxuan said urgently. She quickly took a stack of Talismans from her Storage Pouch but hesitated to throw them. Faced with such a pure elemental creature, ordinary Talismans would likely have little effect.

"Everyone step back." Just as the three women were at their wits' end, Lin Yuan's calm voice sounded. He stepped forward slowly, standing shoulder-to-shoulder with Ye Youmeng, his gaze examining the Ice Flame Fire Bird with great interest.

"Interesting. Born in extreme Yin, raised in a land of Evil Qi, gathering ten thousand years of cold Qi to become a spirit."

"Little Ice Bird, don't stay in this desolate gully. Come with me, and I'll take you to see the sights of the world. I guarantee you'll live in luxury, how about it?" His voice carried a tone of ridicule and temptation, like a seasoned veteran.

However, the Ice Flame Fire Bird responded with an even more violent attack! It opened its beak, and a pale white flame beam, several times thicker than before, like a divine spear capable of freezing the heavens and earth, pierced straight toward Lin Yuan's forehead!

"You refuse a toast only to be forced to drink a forfeit." Lin Yuan curled his lips, advancing instead of retreating. "Since you don't appreciate the mood, I'll have to use force."

With a thought, a dark blue flame erupted from his palm! Earth Core Nether Fire!

The extremely Yang and hot Heavenly Spirit Fire met the extremely Yin and cold Profound Fiend Ice Flame at this moment, in this narrow valley, clashing violently!

"Boom!" A dull explosion sounded, not the bursting of flames, but the violent collision of two extreme energies, cold and heat!

Centered on the point of contact between the two flames, a visible white shockwave suddenly spread outward, shaking the hard Evil Qi ice on the ground into cobweb-like cracks.

The temperature of the entire valley fell into a strange chaos. At times it felt like falling into an ice cellar, and at others, like facing a furnace.

The dark blue and pale white lights intertwined and devoured each other frantically, stirring up large swathes of thick fog that shrouded the entire battlefield.

Lin Yuan's figure appeared and disappeared within the mist. He did not cast any flashy Spells, but simply urged the Earth Core Nether Fire to engage in the most primitive and pure energy confrontation with the Ice Flame Fire Bird.
