Chapter 448: Ten Thousand Swords Flow Formation

A loud, thunderous boom! The phantom image of the Underworld King collided with the two fists of the Yin and Yang Qi Dharma Image! However, looking from the outside, this Demon Emperor's Yin and Yang Qi Dharma Image was much larger than Zhang Nuo's Underworld King phantom, with a difference of at least half in size!

At the very moment the two fists met, Zhang Nuo's figure retreated several dozen zhang, while the Yin and Yang Qi Dharma Image did not even budge; seeing this, anyone with a discerning eye could see the gap between them!

Steadying his figure, Zhang Nuo could not help but secretly marvel in his heart! It truly lived up to being something evolved from the Yin and Yang Qi, the mother-Qi of all things; its power was truly overbearing!

"Zhang Nuo! Return the ancient book to me!"

The Demon Emperor looked at Zhang Nuo in a great rage at this moment, reaching out his hand to demand that Underworld Ancient Book from him!

"If you return the ancient book to me, perhaps I can still persuade the people of the Great Underworld Mansion not to come and attack Yulong Immortal Mountain this time!"

"Haha! Demon Emperor! You yourself are just a lackey of the Great Underworld Mansion, why would they listen to you!"

Zhang Nuo let out a long laugh, as if he had heard an extremely funny joke!

"You..."

Insulted by Zhang Nuo once again, bloodshot veins burst into the Demon Emperor's eyes! However, what the other party said was not entirely unreasonable; his status in the Great Underworld Mansion at this time was truly not very high! His words just now were merely an attempt to deceive people!

Just at the moment the Demon Emperor hesitated slightly due to anger, Zhang Nuo lifted his left hand, and two Flying Swords materialized from his side; a high-pitched dragon roar resounded through the sky as two Silver Dragons charged toward the Demon Emperor!

This time, upon learning that the Underworld Ancient Book was on Zhang Nuo's person, the Demon Emperor could no longer restrain his impulsive emotions; he suddenly raised both hands and pointed at the distant Zhang Nuo! At the same time, several strands of pure Demonic Qi surged from between his ten fingers, and with a single coil, they wrapped around the small black halberd.

The next moment, the Yin and Yang Qi Dharma Image grabbed the black halberd with one hand, aimed precisely at Zhang Nuo, and then with force from its wrist, threw the small black halberd out!

*Swish! * A black streak flashed by, just like a black bolt of lightning striking in mid-air! Throughout the void where the small halberd passed, ripples like water waves appeared, and an immense pressure shrouded everything within a radius of several dozen li!

Zhang Nuo's heart sank; the moment the small black halberd left the hand, his heart skipped a few beats. With the speed and force of this strike, even if he used the sturdiest Magic Treasure on his body, he would have no hope of blocking it!

At this moment, the speed of the small black halberd had reached an inconceivable level! In just the blink of an eye, it had reached right in front of Zhang Nuo! The waves of power brought by the void fluctuations made Zhang Nuo's body appear somewhat ethereal!

With no time to think, Zhang Nuo quickly flipped one hand, and a mass of Silver Flame swept out from it; as he swung it in front of him, a pair of wings manifested from the silver flames!

These wings were over two zhang long, a full double the size of the Butterfly Wings. The moment the silver flame wings appeared, Zhang Nuo stepped slightly forward, landing just in front of the wings, and in an instant, the pair of wings seemed to grow onto his body!

As all four wings moved in unison! *Swish! * With a sound, Zhang Nuo vanished from where he stood! And the very instant his body disappeared, the small black halberd pierced through the spot where he had been standing just before!

The Demon Emperor had used his full strength for this strike just now, thinking this move would surely put Zhang Nuo to death, but who would have thought that Zhang Nuo's speed would reach such a terrifying degree that he vanished completely without even leaving a trail!

The Yin and Yang Qi Dharma Image beckoned with one hand, and the halberd that had missed its mark returned to its grasp. At this time, the Demon Emperor's Divine Sense swept toward the surroundings, and suddenly he turned his head sharply to see Zhang Nuo's figure appearing in the high sky hundreds of zhang away!

As for when Zhang Nuo had appeared, the Demon Emperor had no idea! He only saw two pairs of wings, one black and one white, flapping incessantly behind Zhang Nuo; the silver-white wings were clearly much larger than the Black Butterfly Wings, but the two combined perfectly, looking quite harmonious from afar!

Just now, in order to dodge the attack, Zhang Nuo had no choice but to activate a move from the 'Flame Control Technique', the 'Wing Transformation Technique!' This move had almost no offensive capability; it merely transformed flames into the shape of wings to amplify a cultivator's speed!

In this way, with the speed boost from two pairs of wings, a single flap carried him hundreds of zhang away! Waking up from the daze of a moment ago, his heart couldn't help but feel a surge of joy! Turning his head back to look at the two pairs of wings behind him, Zhang Nuo raised an eyebrow, moved his body again, and vanished from the spot! The next moment, he appeared in another place hundreds of zhang away!

"Kid Zhang! Your speed is too terrifying! You can actually compare to the spatial divine ability of Baijiaowang!"

Chunyangzi exclaimed in surprise, feeling Zhang Nuo's uncanny speed, and couldn't stop marveling! Zhang Nuo ignored him, merely extending one finger toward the Demon Emperor and slowly curling it a few times!

This time, it infuriated the Demon Emperor! After an angry roar, the Yin and Yang Qi Dharma Image beside him flashed and charged toward Zhang Nuo!

But just as the Dharma Image was about to close in on Zhang Nuo, he flapped all four wings at once and vanished from the spot in the blink of an eye! The speed of the Yin and Yang Qi Dharma Image itself was already very fast, but facing Zhang Nuo's current speed, it simply could not catch up! The Demon Emperor's heart chilled! He had thought it impossible for Zhang Nuo to repeatedly employ such extreme speed, but everything before his eyes proved his conjecture completely wrong!

Zhang Nuo's figure flickered unpredictably in mid-air; no matter how the Yin and Yang Qi Dharma Image chased, it couldn't even touch the hem of his clothes!

"Demon Emperor! It is time to end this!"

Just as the Demon Emperor was startled, Zhang Nuo's voice rang out from behind him! Hurriedly turning his head, he saw Zhang Nuo shrouded in the Underworld King phantom, his four wings flapping slowly, his hands forming a strange Dharma seal, looking at him coldly!

"Want to kill me! You brat are still a bit too green! When I, the Demon Emperor, were roaming the world, you didn't even know where you were!"

Provoked by Zhang Nuo's arrogant air, the Demon Emperor said bitterly.

"Is that so? Then today, I, Zhang, shall act against the heavens!"

As soon as his voice fell, Zhang Nuo changed his hand seals, and immediately, within a void of several hundred li, a series of sword hums rang out! These metallic sounds were crisp and melodious! They were as pleasant as heavenly music, but when the Demon Emperor heard these sounds, his expression became extremely ugly!

He released his Divine Sense to sweep the surrounding space, feeling greatly shocked. Wherever his Divine Sense passed, the only thing he could feel was the surging of Spirit Power across the sky, and these Spirit Power fluctuations were terrifyingly strong! Even if a dozen Nascent Soul Stage cultivators were to release their pressure in this area simultaneously, they could never achieve such an effect!

Scanning with his eyes once more, the Demon Emperor discovered to his astonishment that, at some unknown time, Zhang Nuo's eighty-one Flying Swords had spread throughout the entire region! The twinkling Sword Qi was the very source of those Spirit Power fluctuations!

"Ten Thousand Swords Flow Formation! Activate!"

Zhang Nuo let out a low shout, and instantly, within the hundred-li void, the sword hums grew even more intense. At the same time, streaks of Sword Qi slashed out, and the crisscrossing Sword Qi tore the surrounding void apart! The Demon Emperor shifted his figure, hiding beneath the Yin and Yang Qi Dharma Image, using the Dharma Image's powerful might to protect his body!

Glancing at the Demon Emperor, Zhang Nuo once again activated the Dharma seals. This time, after a flurry of transformations, the number of Flying Swords in the sky doubled! Whether they were sword shadows or physical entities, they were identical to real Flying Swords, making it impossible for anyone to distinguish the true from the false!

*Swish! * The sound of air being broken rang out, and the numerous Flying Swords moved through this void as densely as fish swimming in water!

In an instant, the sky within this hundred-li radius was filled with the traces of passing Flying Swords; even a cultivator with the most powerful Divine Sense could not distinguish which one was the real Flying Sword!

The sky full of sword shadows caused the surrounding Heaven and Earth Origin Qi to fluctuate, and the explosive sounds of the void shattering came one after another! Under the protection of the Yin and Yang Qi Dharma Image, the Demon Emperor widened his eyes, staring at everything before him in disbelief! At this moment, he dared not move even half a step away from the Dharma Image; the moment he stepped out, he would immediately be hacked into pieces by the countless Sword Qi and Flying Swords!

This move was precisely the sword formation from the Ninth Layer of Zhang Nuo's 'Shangqing Sword Art'! The 'Ten Thousand Swords Flow Formation'! Previously, due to the limitation on the number of Flying Swords, he had been unable to use it, but now that his cultivation had advanced to the Nascent Soul Late Stage, Zhang Nuo had finally revealed this ultimate technique!

At the same time, he was astonished to discover that when this 'Ten Thousand Swords Flow Formation' was activated, it actually drew upon the Heaven and Earth Origin Qi; thus, the attack power of this sword formation could well be imagined!

*Boom! *

Just as Zhang Nuo was marveling at the powerful might of the sword formation, a sword shadow burst open right beside the Yin and Yang Qi Dharma Image. Accompanied by the explosion of this sword shadow, the body of the Dharma Image trembled slightly, yet it still did not harm its core!

But the Demon Emperor, sheltered beneath the Dharma Image, had a face ashen with rage; the Dharma Image, tempered with the Yin and Yang Qi as its foundation, had actually been shaken—this was something he had never encountered in hundreds of years!

*Boom, boom, boom! *

Successive explosions rang out, and the shockwaves generated by the Heaven and Earth Origin Qi were like vast ocean waves, surging and towering! They actually forced the massive Dharma Image to retreat several steps!

Zhang Nuo was overjoyed; if he could use the might of this great formation to directly slay the Demon Emperor, he would not need to reveal the 'Purple Lightning Wild Thunder' within the 'Four Spirits Square Cauldron'! Thinking of this, Zhang Nuo added all the Heaven and Earth Origin Qi stored within his body into the formation!

After a series of explosions, the Yin and Yang Qi Dharma Image was tossed about in the entire formation like a small boat drifting in giant waves! Several times, the power generated by the explosions nearly reached the Demon Emperor himself!

As the 'Ten Thousand Swords Flow Formation' slowly unfolded, waves of powerful Heaven and Earth Origin Qi were rapidly injected into the formation! In the blink of an eye, all the Heaven and Earth Origin Qi within a radius of several hundred li had been drawn over!

At the same time, in a building far away in the Immortal World, an old Daoist wearing a white robe suddenly opened his eyes!
