Lei Jun’s Xuanxiao Immortal Thunder had long been known to Fu Dongsen, yet he had never faced it himself.

Although the Celestial Master Mansion was currently without the Thunder Law Heavenly Scripture Talismans, it could borrow the Supreme Pure Thunder Mansion Cave Heaven and the Celestial Master’s Sword to command the Nine Heavens Divine Thunder.

Thus, with Yang Thunder and Yin Thunder combined, Fu Dongsen and Rong Guangchen had somewhat anticipated it.

Yet the power of this one sword still exceeded Fu Dongsen’s expectations.

*"The Altar of Wanfa Sect and the Mountain Defense Array’s spiritual power were also fueling his mana..."* Fu Dongsen realized inwardly.

The North Abyss Divine Spear, renowned alongside the Celestial Master’s Sword, possessed a North Abyss Mysterious Ice not as fierce as the Nine Heavens Divine Thunder, but its offense and defense were balanced, at the very least ensuring it wouldn’t be broken through in a short time, its grandeur and weight even greater.

Lei Jun combined Yin Yang Divine Might, while Fu Dongsen counted on his superior cultivation realm.

But when the Celestial Master’s Sword further drew on the Altar of Wanfa Sect’s might, it forcibly cleaved through the sharp and heavy edge of the North Abyss Divine Spear. 𝙛𝓻𝒆𝓮𝒘𝙚𝙗𝒏𝙤𝙫𝓮𝒍.𝓬𝒐𝙢

Yet Fu Dongsen remained unshaken, his figure wavering in midair, then merging whole into a stream of light, joining with the North Abyss Divine Spear in midair.

Lei Jun’s next sword stroke struck, but hit nothing.

Fu Dongsen, now one with his spear, transformed the North Abyss Divine Spear into a streak of ice-blue cold lightning, flickering repeatedly across the sky.

For several instants, the magical treasure seemed to completely transcend the shackles of space, darting through the void, ceaselessly shifting its position as it thrust toward the immense illusory altar shrouding Dragon Tiger Mountain.

*The wonders of Immortal Traversal Heavenly Sea...* Lei Jun’s sword missed, but there was still no sign of panic.

Purple and black lightning swirled with exquisite agility, turning and looping of its own accord. As Lei Jun circled his sword, the lightning instantly shaped itself into a ring, encircling Dragon Tiger Mountain.

Purple and black bolts mingled as they formed a purple-black woven Yin Yang Taiji Diagram, shielding multiple flanks and blocking every thrust of the North Abyss Divine Spear darting in from all directions.

The Daoist Artifact Refining Sect, known as the External Alchemy School, called the Eightfold Heaven Realm by the name "Immortal Wandering," itself split into four layers known as Immortal Wandering Four Seas.

The Four Seas were: Human Sea, Earth Sea, Celestial Sea, and Tao Sea.

The Human Sea meant Soul Sea, representing the cultivator’s Immortal Soul’s further growth. Thus, the strength difference between an eighth-realm cultivator and one at the seventh was obvious.

The Earth Sea was when the Artifact Refining Sect cultivator’s Soul Sea connected with earth veins, aiding their practice and giving them unmatched subterranean traversal skills among lineages.

Meanwhile, Celestial Sea meant the Soul Sea connected with the void, as the Artifact Refining Sect cultivator further comprehended the mysteries of space, commanding magical treasures for brief void travel—thus, in actual combat, their combat power sharply surpassed before.

The gap, in fact, was even greater than the leap from Immortal Traversal Heavenly Sea to Immortal Traversal Tao Sea, almost on par with the massive advancement a Taoist Talisman Sect cultivator made from Intermediate Scene of Divine Court to External Scenery of the Divine Court.

Fu Dongsen had reached Perfection in the Immortal Wandering Four Seas realm, his Soul Sea linked to the void, of course. Lei Jun had also anticipated this.

If the other’s Immortal Soul had not fused with the North Abyss Divine Spear before, it might have been different.

But now, with Immortal Soul and magical treasure merged as one, the North Abyss Divine Spear’s sudden appearances were impossible to guard against.

But no matter how it shifted, the target was clear.

So, Lei Jun shaped his sword into rings, laying one purple-black Yin Yang Taiji Diagram after another across all sides of Dragon Tiger Mountain, defending with the Mountain Defense Array so tightly that not even a breeze passed through, unshaken no matter how the world outside howled.

At this moment, Rong Guangchen moved in once more.

As he advanced, his Golden Core retracted back into his body.

Yet a pale golden glow now gleamed across his skin.

His Golden Core at that instant fused with his Nascent Soul, forming the Nascent Soul Transformation Great Elixir.

This former Pure Yang Palace Elder’s fleshly might in both offense and defense advanced yet another step beyond before.

He drew near to Dragon Tiger Mountain, and within the floating purple-black Taiji Diagram, Yin Yang lightning instantly struck forth.

Yet, not facing the Celestial Master’s Sword’s direct assault, Rong Guangchen no longer dodged, but instead withstood a strike of lightning head-on, relying on the Great Elixir’s formidable defense.

Then, platinum fire appeared again, burning against the purple-black Taiji Diagram.

Lei Jun did not turn his sword toward Rong Guangchen, focusing instead on facing Fu Dongsen and the North Abyss Divine Spear.

*If I got distracted, the combination of Fu Dongsen and the North Abyss Divine Spear would immediately hammer and bombard one single point.*

By siege potential and destructive power, his threat was greater.

*As for other ways to handle Rong Guangchen, Lei Jun felt no urgency to act just yet.*

Qingxiao Manor was not famed for magical duels, after all.

Both Hong Jie and the Taiyi Primordial Tower had yet to appear.

The supposed Emperor and the Thousand Leaves Butterfly King—who might also intervene—had not revealed themselves, either.

The dangers indicated by those two moderately unlucky lots might not simply lie in wait, but instead lurk for a timely strike.

Meanwhile, the great battle had already begun drawing the earth veins to shift, but the Celestial Master Robe remained missing...

As Lei Jun’s swordlight flowed, Yuan Mobai provided his aid.

The Supreme Pure Thunder Mansion Cave Heaven now almost seemed to merge with Dragon Tiger Mountain’s main peak.

Countless bolts of purple thunder crashed down from it, like a deluge, inundating Rong Guangchen’s Pure Yang True Fire.

Rong Guangchen was patient and steady, unhurried.

Above, Fu Dongsen struck swiftly but in well-ordered fashion.

Behind, Gu Han did not rush into the fray, but remained by Wei Qiyue’s side as her protector.

Over Wei Qiyue’s head at that moment floated two flying swords.

One, her best-known lifebound magic treasure, the Dust Silk Sword, retained its original form and did not yet split into tens of thousands of thin blades.

The other flying sword, its brilliance condensed, now showed itself as a Heavenslicer Great Sword.

This was the Severing Dust Sword, the second lifebound flying sword Wei Qiyue forged after reaching the Upper Three Heavens cultivation.

Unlike the Dust Silk Sword’s supple, unfathomable transformations—imbued always with worldly flame and smoke—

The Severing Dust Sword was fierce and unyielding.

To sever dust was to sever attachments, sever the mundane world, one sword ending two ties.

The sword qi, sword light, and sword intent continued to gather and accumulate, surrounded by myriad runes and Tao containment, all running in harmony.
