The sword spirit's voice suddenly rang out across the lake of Li Guanqi's mind, heavy with utmost gravity.
Li Guanqi's gaze turned sharp as a blade. In his mind, he asked in a deep voice, "Can you discern what realm this Upper Realm immortal is at?"
"Are they very strong?"
The sword spirit's exceptionally solemn voice sounded slowly.
"Very strong! Though I cannot be certain of their identity..."
"He must be killed!"
Li Guanqi narrowed his eyes slightly. He understood that the Cang Lu before him was definitely here searching for the sword spirit.
Yet right now, Cang Lu definitely had not detected her presence.
*Boom! Boom! Boom! Boom!*
Cang Lu's aura surged abruptly to the mid-Void Refining Realm.
Perhaps that borrowed power was also wary of something, for it lacked the overwhelming ferocity it had displayed at the very beginning.
Cang Lu smiled faintly as the tremendous strength coursed and roared through his body.
Sitting cross-legged where he was, the guqin hovered above his knees.
Li Guanqi pulled the barrier closed once more and charged forward without the slightest hesitation!
Afterimages swung swords through the air simultaneously. With a grim expression, Cang Lu plucked the strings rapidly with both hands!
This time, the sound blades carried an eerie silver sheen. Just as they were about to collide with the sword rays, they tore through space in an instant, piercing right through the sword light!
The instant Li Guanqi sensed it, he shifted laterally several inches.
*Slash!*
Two sound blades grazed past his ear. His left ear was sliced off in a flash, along with a chunk of flesh carved from his shoulder.
The remaining sword rays were shattered in succession by the sound blades.
This time, the sound blades released by Cang Lu's playing were noticeably superior in both power and speed.
A calm, composed expression surfaced on Cang Lu's face. Li Guanqi rolled his neck, which immediately popped with a crackling like beans roasting in a bamboo tube.
Within him, the Dragon Elephant Prison-Suppressing Art surged into motion. In that moment, Li Guanqi's vitality boiled, sounding as though dragons and elephants were roaring incessantly.
Muscles bulged across his entire body. The terrifying force of merely swinging his arm warped and twisted the surrounding void.
Seeing this, Cang Lu's expression shifted slightly, and he slowly stood up.
Li Guanqi's physical strength was now comparable to a Rank 6 great demon!
Horrifying sword intent vented unreservedly. He gathered all of his thunder primal energy back into his body, while the power of the heavenly flames clung to the sword blade.
Yanluo trembled slightly, letting out a clear, resounding sword cry.
In this state of eruption, Li Guanqi possessed terrifying strength, further compounded by the weight of ten thousand jun granted by Yanluo's Soul Release.
It could be said that a mere light swing of the sword was enough to split mountains.
Within Li Guanqi, his origin spirit sat cross-legged inside his dantian, pouring out monstrous primal energy.
*Thump!*
The moment Li Guanqi moved, the void beneath his feet shattered!
Cang Lu's eyes narrowed. He instantly raised the guqin in his hands and brought it across horizontally to block at his flank!
*Crack!*
The pitch-black blade slashed horizontally toward his neck. Though golden patterns flickered with faint light across the guqin's body, they still could not hold back the deluge of terrifying force.
The guqin cracked on impact, and the blade continued cleaving toward Cang Lu's neck!
At the critical juncture, Cang Lu spun the guqin in an attempt to deflect the sword's trajectory.
Yet he discovered that no matter how much force he exerted, the path of the sword momentum did not shift in the slightest.
Groans of overburdened cracking echoed from the guqin. Seeing that the horrifying sword light laced with thunder and heavenly flame was about to erupt, Cang Lu made an immediate decision: discard the guqin to save his life!
*Boom! Boom! Boom! Boom!*
Terrifying sword light erupted in an instant, and the violent blast made all of Yuntian City shudder slightly.
The guqin blew apart into countless shards, its strings snapping.
Yet the shockwave of power still slammed into Cang Lu.
Cang Lu was blasted backward like a cannonball, slamming into the barrier's wall with a heavy thud.
"*Pfft!*"
Cang Lu violently spewed a mouthful of blood mixed with bits of mangled flesh.
The sheer shockwave of that horrific force had displaced all his internal organs.
Even using the secret technique of invoking an immortal's name, he still could not withstand Li Guanqi.
Cang Lu felt as if his entire body had fallen apart, as though he had been rammed by an ancient great demon.
Before he had a chance to catch his breath, the void where Li Guanqi stood abruptly exploded, followed by a piercing sonic boom.
Without a second thought, Cang Lu instantly crushed the bracelet on his wrist.
*Bang!*
The mere sharpness of the blade shattered the golden light barrier in an instant.
Yet that split second of delay was enough for Cang Lu to pull out another guqin, this one pitch-black all over.
However... the quality of this zither was inferior even to the previous one.
*Boom!*
Watching Cang Lu's hurtling figure, Li Guanqi struck second to gain the upper hand, appearing at his side in an instant.
His formidable physique made his speed all the more terrifying.
As Cang Lu retreated, his fingers plucked at the strings.
His eyes sharp as blades, a profound aura abruptly radiated outward, and terrifying power erupted!
"Demonic Music: Chaotic World!"
*Clang! Clang! Clang!*
This time, the terrifying melody did not release sound blades. The music entered Li Guanqi's ears.
Instantly, Li Guanqi's sea of consciousness felt as if it had suffered an inexplicable assault.
The Dao platform in his sea of consciousness trembled, his mind grew slightly dazed, and the world before him abruptly began to feel unreal.
Yet the very next moment...
Before the illusion could fully form, the illusory world before Li Guanqi's eyes abruptly shattered!
Li Guanqi looked toward Cang Lu and spoke with disdain:
"I didn't even have a heart demon tribulation when breaking through to the Void Refining Realm. You think a mere musical illusion can trap me?"
"A fool's pipe dream!"
Cang Lu's eyes filled with horror. He had never expected the demonic music he took such pride in to fail against Li Guanqi.
Li Guanqi raised his hand and unleashed three sword strikes!
All three stances of the Heaven Breaker Sword Art erupted in an instant.
The mark between Cang Lu's brows blazed with blinding radiance, forming a barrier of spiritual sigils before him.
The terrifying sword light even ripped through Li Guanqi's own barrier wall.
The surging, torrential sword light tore open the void. Vast expanses of space collapsed, reducing the space within the barrier to what seemed like total nothingness.
*Boom! Boom! Boom!*
In Yuntian City, violent tremors reverberated, causing pavilions and towers to collapse in droves.
The watching cultivators outside changed color as three sword rays suddenly shot outward!
Frightened, the cultivators scrambled out of the way.
When Li Changqing saw these three sword strikes, his eyes narrowed, and he muttered in a low voice, "A Heaven-rank sword art!"
Meng Wanshu's eyes brightened slightly; the sword light broke through her wandering thoughts.
Inside the barrier, right after Li Guanqi delivered the three strikes, the cracking sounds of the spiritual sigils on the verge of breaking reached his ears.
He kicked off forcefully, plunging into the explosion. His right hand clenched in the air, instantly manifesting a scabbard woven of thunder and flames.
Li Guanqi's eyes were as sharp as an eagle's. Crouching low, the muscles of his back bulged high, making him resemble a ravenous beast ready to devour its prey.
Sheathed, Yanluo crackled with entwining lightning. With a roar from Li Guanqi, a terrifying sword beam flashing with thunder and fire slashed out!
"Sword Draw Stance!"
*Boom! Boom! Boom! Boom!*
A terrifying sword light spanning more than three hundred zhang erupted. Cang Lu's pupils contracted into needlepoints.
He poured everything into throwing up dozens of primal energy barriers!
Yet before this sword strike, those barriers were as fragile as porcelain.
With overwhelming, destructive force, the sword light engulfed Cang Lu.
At death's door, Cang Lu fixed his eyes on Li Guanqi, a sinister smile creeping onto his lips.
Slicing through the barrier, the sword light actually sheared off a tenth of Yuntian City as it floated in midair!
As chunks of earth plummeted, Li Guanqi stepped coldly beside Cang Lu.
Enveloping him in terrifying power, a sensation of coolness washed through Li Guanqi's mind as he immediately enacted the soul-searching method the sword spirit had just taught him.
Digging all five fingers into Cang Lu's skull, his divine sense surging wildly, Li Guanqi roared, "Soul Binding!"
Yet a few breaths passed, and the corpse of Cang Lu in his grasp abruptly blew apart!
*Bang!*
Still unsatisfied, Li Guanqi sent both heavenly flames sweeping through the entire interior of the barrier!
Any remaining soul power was incinerated completely.
With slight bewilderment in his eyes, Li Guanqi murmured, "A wisp of an origin spirit... He really was an avatar!"
The barrier dissipated, and a figure threw herself into his embrace like the wind.
