Countless streaks of Golden Crow Divine Light swept across, resembling the explosion of hundreds of layers of Golden Crow Divine Light.

Amidst the violent explosions, however, layers of invisible black aura condensed into rings, continuously devouring the explosive Golden Crow True Flame.

Within appeared a terrifying giant serpent over a hundred feet long, its body coiled, surrounded by an invisible black radiance that spread like a wave.

The Taiyin Fairy at this moment pushed aside Zhang Jian beside her, seeing him clothed in azure Cloud Brocade Silk, her expression slightly shocked, but still she spoke.

"Your Majesty?"

Zhang Jian slightly raised his hand.

"Let me first deal with this Evil God, then we'll have a proper discussion!"

Earlier, he had noticed that the vitality of the Outer Demon God was exceptionally strong, its flesh not only capable of continuous enhancement and division but also able to devour Divine Power, starlight, and even astral winds to strengthen itself and transform into Magic.

This method was somewhat similar to the Reincarnation White Hole in the Little Heavenly Reincarnation Technique, but even more powerful.

Hence, he tested it with the Golden Crow Divine Light.

Unexpectedly, it even resisted the explosive Golden Crow Divine Light.

"No, it's not that it can resist; it's that the special Heaven and Earth Law Power allows it to recover and devour quickly, as long as they can be interrupted!"

Zhang Jian didn't use the Sheji Emperor's Authority.

Using the Sheji Emperor's Authority felt like using a cannon to shoot a mosquito.

A red and a white Divine Light instantly flowed around him.

The Taiyin Refining Form Divine Light and the Golden Crow Fission Divine Light intertwined, instantly spawning countless Yin Yang Arc Blades. The red and white blades slashed fiercely at the Outer World Snake Mother, yet the Snake Mother was extremely cunning. Around her, countless serpent scales converged, forming a gigantic Snake Scale Shield before her.

Zhang Jian's massive Primordial Spirit Divine Sense noticed that the Snake Scale Shield was covered with countless strange Demon Patterns, containing a majestic and vast Divine Power.

Zhang Jian's mind flashed with images of Outer Demon Gods.

True Monarch Zhanmo mentioned an exceptionally terrifying Outer Demon God deep in the Outer Space, known as the 'Infinite Snake'!

The 'Infinite Snake' possessed incredible power, its ferocity renowned.

At this time, seeing Zhang Jian 'snatching food from a serpent's mouth,' the Outer World Snake Mother grew more vicious. Behind her, countless black auras expanded, many serpent shadows appeared within, abruptly manifesting a heaven-shaking serpent shadow. The light of the surrounding starry sky seemed to be swallowed by this terrifying serpent shadow, rapidly devouring in their direction.

The black aura devoured the void, sweeping across the sky.

"If you want to devour, then devour to your heart's content!"

Seeing this, Zhang Jian raised his hand, and countless purple-yellow lights flowed out, instantly transforming into a vast pointed cone.

It was the Super-Terramancy Immortal Technique "Mountain Drilling Cone"!

At this moment, even without the Supreme Treasure King Jun Golden Man, Zhang Jian could wield this True Immortal Level Immortal Technique.

The purple-yellow Immortal Light flowed over, instantly converging on the devouring giant serpent.

The terrifying Power of the Earth poured into it, causing the giant serpent to emit a painful hiss!

What surprised Zhang Jian was that after swallowing a True Immortal Level Primordial Spirit Immortal Technique, the serpent only felt slight pain and quickly began to devour again.

"Such bizarre infinite power!"

Zhang Jian thought to himself, as a pure Yin Yang Divine Light intertwined around him, black and white light interweaving, which was no longer a composite Yin Yang Immortal Technique formed by the Taiyin Refining Form Divine Light and the Golden Crow Fission Divine Light.

But the True Immortal Immortal Technique "Innate Yin Yang Extinction Divine Light"!

The brilliant light majestically surged forth, directly entering the mouth of the devouring giant serpent at its appearance.

The blazing Innate Yin Yang Extinction Divine Light swept through, where it passed, the shadow of the Infinite Snake emitted an unbearably painful hiss, collapsing inch by inch, extinguished by the Innate Yin Yang Extinction Divine Light.

This type of flesh and blood Magic, skilled in vitality and replication, met its nemesis when faced with extinction-type Immortal Techniques.

Countless Innate Yin and Yang Qi intertwined and enveloped the Outer World Snake Mother, who in her anger and alarm, her body surface exploded with black aura, which then split into two!

She actually abandoned a portion of her origin to form the Outer Demon God's body.

It was apparent she intended to shed her tail to escape!

Zhang Jian, would not let her leave easily.

Eliminate the roots, or the spring wind will give new life.

An immense Dao Map blanketed the void, silently engulfing the Outer Demon God within. The Map of Mountains and Rivers instantly seemed to evolve Universe Heaven and Earth transformations, its endless might consuming the Outer World Snake Mother, turning it into dust, its vitality thoroughly absorbed and purified.

The Taiyin Fairy stood aside, witnessing this scene, a change flickering in her eyes.

This Outer World Snake Mother's Dao Practice was not simple, with not only Daoist Magical Power nearing True Immortal Level but also the descendant of the 'Infinite Snake'. Among Outer Demon Gods, it was not an unknown entity, yet it could not withstand a few moves in the hands of this Great Xia Emperor.

No support from the Great Xia Dragon Qi or the Great Xia Emperor Qi here!

Solely relying on one's Dao Practice and Magical Power.

Zhang Jian took another glance around, waving his hand took the Taiyin Fairy into the depths of a distant star.

"Do you have something you want to tell me?" 𝒻𝘳ℯℯ𝑤ℯ𝒷𝘯ℴ𝓋ℯ𝘭.𝑐ℴ𝑚

At this moment, atop a majestic mountain range, Zhang Jian gazed up at the grand Taiyin Star overhead, his expression serene.

The cool moonlight at this moment fell from above, covering this star like frost and snow.

The Taiyin Fairy pondered briefly before speaking.

"I am a disciple of the Guanghan Immortal Palace, which originally was a branch of the Xiyue Sword Sect. Over the years, we have been pursued by the Taiyin Demon Palace!"

Zhang Jian pondered slightly, then suddenly said, "So, you willingly entered the Demon Suppression Tower back then?"

The Taiyin Fairy, upon hearing this, had a trace of reminiscence in her eyes. "When the Guanghan Immortal Sect was destroyed, I was fortunate enough to meet the Dong Shen Ancestor, who intended to assist us. Of course, he also wanted a Supreme Treasure from our Guanghan Immortal Palace!

So we made a transaction!"

Zhang Jian's gaze remained steady as he spoke blandly. "If I saw correctly just now, those from the Taiyin Demon Palace were chasing you. Why have they been relentlessly pursuing you for so many years? Tell me this is just an accident!"

The Taiyin Fairy glanced at Zhang Jian, her eyes filled with a hint of hesitation. After a moment, she spoke.

"They're after the secret key!"

Zhang Jian's expression shifted upon hearing this.

The Taiyin Fairy sighed inwardly, knowing there was no longer a need to hide anything.

Furthermore, the Great Xia Emperor had displayed such Dao practice that it evoked some thoughts within her.

The Xiyue Grotto Heaven was so perilous that she doubted her ability to obtain the complete legacy of the Xiyue Sword Sect alone. She would need external assistance to retrieve the sect's heritage items.

After some thought, she said, "That secret key is the key to accessing the core legacy of the Xiyue Grotto Heaven!"

Upon hearing this, Zhang Jian's eyes brightened with interest.

The Taiyin Fairy spoke softly:

"Back then, the Xiyue Sword Sect faced an unexpected disaster. The ancestors felt they couldn't resist the enemy, so they sealed the seeds and the legacy within the sect's core secret area, and the key to unlocking this core legacy was taken out by the disciples and followers around them!"

"However, the ancestors miscalculated one thing: the enemy of the Xiyue Sword Sect was even more terrifying than imagined. That person hated the entire Xiyue Sword Sect, banishing the Xiyue Grotto Heaven into the depths of the starry sky, so much so that the descendants of the Xiyue Sword Sect could not enter it for hundreds of thousands of years, and over time, this secret was gradually lost!"

"Such a time span of hundreds of thousands of years..."

Zhang Jian mused inwardly, his anticipation for the treasures of the Xiyue Sword Sect rising markedly.

Such a long time was enough to turn the seas into mulberry fields.

Who knows if the treasures within still exist.

"This is the secret key, and I am willing to offer it to the Emperor!"

The Taiyin Fairy raised her hand, and from the depths of her palm, a moon-white flowing light slowly emerged. In an instant, a uniquely styled moon-white longsword flew out from within her, landing in front of Zhang Jian.

Zhang Jian casually took it into his hand.

The moon-white longsword before him seemed as if cast from Taiyin Ice Crystal, completely crystalline, with a sword hilt wrapped in a cyan-gold crescent, covered in numerous intricate ancient patterns, and a sword body adorned with flowing water-like sword patterns.

In the sword patterns, countless ripples flowed, resembling the Dao Rhyme of the Taiyin Path.

Essentially, its quality was extremely high!

"An Immortal Treasure!"

The concept flashed in Zhang Jian's eyes.

An Immortal Treasure refers to a magical treasure imbued with the Immortal Dao Law.

This was far more formidable than a pure Spirit Treasure, containing the power of the Immortal Dao Law, which, when used skillfully, was invincible.

Similar to the King Jun Golden Man in his hand, which contained six types of Immortal Dao Immortal Techniques, in essence, it was an Immortal Treasure.

Zhang Jian glanced at the Taiyin Fairy and casually tossed the sword back. The fairy sword instantly returned to the Taiyin Fairy's hand.

Seeing this, the Taiyin Fairy's expression showed surprise as the treasure unexpectedly returned to her hand.

As a Primordial Spirit Grand Master, she was well aware of the help a Primordial Spirit Master provided in wielding an Immortal Treasure.

Without this fairy sword earlier, she wouldn't have been able to contend with a terrifying Outer Demon God for so long.

She would have surely perished in an instant.

Zhang Jian said indifferently, "Keep this treasure for now. When I need it, I will ask you for it!"

The Taiyin Fairy gently nodded upon hearing this and then put the 'secret key' back into her body.

She feared the Great Xia Emperor before her might not be uninterested in the treasure, but perhaps wanted even more.

Nonetheless, this gesture somewhat calmed her heart.

She was unafraid of the other wanting more. As long as she could get what she wanted in return, she was willing to serve.

Half a month passed quickly.

Zhang Jian, with the Taiyin Fairy, scavenged a few more areas in the middle layer, finding limited resources, then directly headed to the meeting place with the Taiyin Fairy.

The inner layer gate.

It seemed to be the boundary between light and dark, with one side a world of snowy white like silver frost, and the other filled with countless dark hues.

Inside was seemingly filled with countless perilous energies.

There was a continent floating in the depths of the darkness.

From the junction of the starry sky, one could hear the roars of battles among star beasts within.

When Zhang Jian arrived with the Taiyin Fairy, five Primordial Spirit Great Cultivators from the Tongshan Dao Lineage were already present.

But not everyone was ready to enter the inner layer this time.

Zhang Jian noticed that one of the Primordial Spirit Masters was severely injured.
