Chapter 639: Black Demon Thunder

In the outer sea of the Demon Thunder Sea, Zhang Nuo flew alone high in the sky; the continuously falling heavenly thunder, like sharp swords, made one's heart turn cold!

After parting ways with Jialouluo and Monk Jiemie, Zhang Nuo flew out of the Inner Sea alone. Along the way, Zhang Nuo kept reflecting on the True Immortal Realm. It seemed that in every corner of the world, there existed hostility; even True Immortals, who could live forever, had times when they fought for their lives! For the sake of selfish desire, they could actually disregard the fate of countless living beings!

What kind of existence is an Immortal? People in the world suffer and cultivate continuously to seek to become a True Immortal, but once they become an Immortal, it is a completely different scene! In the eyes of the world, the supreme position of an Immortal turns into a void!

This trip to the Demon Realm brought Zhang Nuo many gains, but at the same time, his understanding of Immortals completely changed the deeply rooted thoughts in his mind!

After flying for several months, suddenly, Zhang Nuo discovered a layer of black electric arcs shimmering in the seawater below!

"Black Demon Thunder!"

With a turn of his thoughts, he recalled the incident before entering the Nei Hai, where he was hunted by a 'Black Electric Cloud-Spraying Beast'! Now that the main task was finished, it was time to get his hands on this fellow that possessed the 'Black Demon Thunder'!

The sea beast itself, while powerful, was not what Zhang Nuo wanted; the only thing he was interested in was the Black Demon Thunder. If he could find this thunder as well, then he would only be missing the last type of lightning to collect the five great strange thunders recorded in the 'Five Thunders Taboo Canon'!

In the Five Thunders Taboo Canon, not only were the methods for using lightning recorded, but there were also various uses for the five great strange thunders, especially refining all five into one's body, which could trigger a powerful art!

This kind of art was called a Taboo Art in the canon. The reason for this was that the lethality of this art was too great and it was overly cruel, which was why it was listed as a type of forbidden art!

Looking at the black thunder light on the sea surface, Zhang Nuo released his Divine Sense and discovered that there were no other sea beasts around. Immediately, his figure swayed slightly and he plunged into the seawater!

A moment later, a powerful fluctuation suddenly erupted on the sea surface. Monstrous waves rolled wildly into mid-air, and streaks of black lightning appeared in the seawater for hundreds of miles around! The crackling sounds were sharp and ear-piercing!

Just at this moment, a streak of light escaped from the seawater and stopped in mid-air. The person within the light was naturally Zhang Nuo! He looked grim, his eyes narrowed slightly, and on his shoulders appeared the heads of Xuanjin and Qiongqi.

"Master! This 'Black Electric Cloud-Spraying Beast' is too powerful; in the water, we are simply no match for it!"

A red light flashed in Qiongqi's eyes as he said in a deep voice!

Just a moment ago, Zhang Nuo had fought with the 'Black Electric Cloud-Spraying Beast' on the seabed, but the result was far beyond his expectations. Although he had advanced to the Late Void Refinement Stage, under the water, nearly half of his divine abilities were suppressed, and he was actually no match for the 'Black Electric Cloud-Spraying Beast'. After several exchanges, he had almost suffered a major loss!

It seemed that a strong dragon could not suppress a local snake; in the water, it was the world of the 'Black Electric Cloud-Spraying Beast'! Zhang Nuo could only stand aside!

"If it doesn't work in the water, I will lure it out!"

Zhang Nuo was also somewhat angry. Having just advanced to the late stage, he encountered such a thing. If he couldn't even deal with a 'Black Electric Cloud-Spraying Beast', how could he talk about going to the Underworld! Thinking of this, he let out a cold snort, golden light flowed between his fingers, and he pressed his hands toward the void of the sea surface below!

Immediately, two palm prints, each hundreds of miles in size, appeared on the sea surface below. A tremendous pressure quickly caused the seawater to part to both sides!

The surrounding seawater seemed to be boiling, with countless sprays surging; the scene was extremely spectacular. In the blink of an eye, two water walls hundreds of feet high appeared, and deep on the seabed, that 'Black Electric Cloud-Spraying Beast' was looking at Zhang Nuo with rolling eyes!

"Awoo!"

The Cloud-Spraying Beast let out a loud roar, shaking the surrounding seawater, and the water walls almost collapsed! However, Zhang Nuo increased the force in his hands and forcibly stabilized them!

"Xuanjin! Qiongqi! Attack!"

At Zhang Nuo's command, Xuanjin and Qiongqi immediately spat out beams of light, launching an attack on the 'Black Electric Cloud-Spraying Beast' on the seabed! Seeing that there was no advantage in staying in the sea, the 'Black Electric Cloud-Spraying Beast' soared straight up, rushing out of the sea surface. With a light flick of its massive body and tail, it scattered all the attacks launched by the two beasts!

Seeing that the 'Black Electric Cloud-Spraying Beast' had come up, Zhang Nuo immediately withdrew his technique, and at the same time, he flicked his sleeves, and eighty-one Flying Swords appeared, floating in a row before him!

These Flying Swords were originally Zhang Nuo's life-bound Magic Treasure, and after being tempered by Yin and Yang Qi, the sword bodies had become very transparent, just like crystal! Their power had increased several times over!

With a hum, dozens of Flying Swords slashed toward the 'Black Electric Cloud-Spraying Beast' simultaneously! The beast's scales provided extremely strong defense, and it flapped the two pairs of fleshy wings on its back to dodge within the sword light. Despite its massive size, its movement speed in mid-air was not slow!

But several Flying Swords still slashed onto the body of the 'Black Electric Cloud-Spraying Beast'! To Zhang Nuo's great surprise, as soon as these Flying Swords touched the scales of the Cloud-Spraying Beast, they shattered instantly, turning into specks of spiritual light that drifted away!

Witnessing this scene, he took a deep breath. What kind of defensive strength was this, that even his life-bound Magic Treasure could not injure it in the slightest!

Those shattered Flying Swords condensed in the air and transformed back into sword shapes! At this point, the Flying Swords had shifted from physical entities to sword intent; even if destroyed, they could be restored instantly!

After several rounds of controlling the Flying Swords to attack, the sky was filled with fragments of shattered swords, yet the 'Black Electric Cloud-Spraying Beast' had not suffered any damage! Instead, it had stirred up the beast's anger!

After a heaven-shaking long howl, a black Thunder Ball was spat out from the mouth of the Cloud-Spraying Beast. The Thunder Ball was only a zhang in size, and as soon as it left its mouth, it exploded! Instantly, black lightning was everywhere in the void for nearly a thousand miles! Zhang Nuo, caught in this field of lightning, felt his body being struck every single moment!

Although this 'Black Demon Thunder' could not cause too much damage to his currently tough physical body, it was not a good thing if it continued for a long time!

Thinking of this, Zhang Nuo's whole body shook, shaking off the black lightning attached to his skin, while purple electric arcs flashed on his body surface, and all his Purple Lightning Wild Thunder was released, protecting him within!

The two types of lightning were like water and fire that could not mix, instantly intertwining. On the other hand, Zhang Nuo used his Divine Sense to trigger the Ten Thousand Swords Flow Array!

Countless sword shadows converged into a torrent and attacked the 'Black Electric Cloud-Spraying Beast' once again! Although the beast was not afraid of the sword slashes before, it felt some apprehension when facing the massive torrent of swords, and immediately, countless black lightning bolts appeared on its body surface to defend!

Boom!

Because the body of the 'Black Electric Cloud-Spraying Beast' was too large, the torrent struck it squarely, knocking the Cloud-Spraying Beast hundreds of feet away!

The beast let out a cry of pain, and then its body swayed, actually shrinking to half a zhang in size! This surprised Zhang Nuo, as in the previous battle, the beast had never shrunk; it seemed that the previous strike had truly caused it to suffer!

The hundred-zhang body suddenly became small, and the target for the attack also became small instantly! When several torrents launched their attacks again, they were all dodged by the 'Black Electric Cloud-Spraying Beast'!

Zhang Nuo's pupils shrank suddenly! A faint cold smile appeared at the corners of his mouth! Since this sea beast had a strong physical body, he would simply compete with it in physical strength!

Zhang Nuo had full confidence in his own physical body. After whispering a few words to Xuanjin and Qiongqi, the two Spirit Beasts retreated into Zhang Nuo's body!

At the same time, Zhang Nuo crouched slightly, and a wolf howl erupted from his throat! Following that, his figure rolled in mid-air and transformed into a two-zhang-long two-headed giant wolf!

This was the first time Zhang Nuo had appeared in this form since refining the Two-Headed Wolf King! The two wolf heads roared toward the sky together, the long howl echoing through the sky, making the dark clouds in the sky tremble!

Covered all over by a layer of faint purple electric arcs, the two-headed giant wolf leaped and pounced toward the 'Black Electric Cloud-Spraying Beast'! The 'Black Electric Cloud-Spraying Beast', which was dodging the attacks of the Ten Thousand Swords Flow Array, was also surprised to find that Zhang Nuo had turned into a two-headed giant wolf, but before it could react, the giant wolf was already upon it!

A wolf claw was raised, and five fierce silver-white claw beams struck through the air! The next moment, the two-headed giant wolf's figure flickered within the purple electric arcs and disappeared from where it was!

In an instant, a rumbling sound of thunder came from above the head of the 'Black Electric Cloud-Spraying Beast', and the two-headed giant wolf appeared! At this moment, it had just blocked the attack of the five claw beams, and before the Cloud-Spraying Beast could recover!

The two-headed giant wolf transformed by Zhang Nuo had already pinned it underneath! A massive wolf tail tightly bound the beast's body, and from the two wolf mouths, two cyan beams of light were spat out!

Boom! Boom!

Two loud bangs rang out, and the 'Black Electric Cloud-Spraying Beast' was struck squarely! On the other hand, the four wolf claws were also clawing at its body incessantly, and more than half of the scales on its body fell off instantly!

"Awoo, awoo" cries of misery came from the mouth of the 'Black Electric Cloud-Spraying Beast'; it never expected that it, a dignified Void Refinement Stage demon beast, would actually lose in physical strength to a human cultivator!

Seeing that the situation was bad, the 'Black Electric Cloud-Spraying Beast' dove headfirst toward the sea; only by returning to the sea was it in its own domain! But how could Zhang Nuo let it succeed?

A gray glow flashed on his body, and he returned to his original appearance! With a quick flip of one hand, two streams of air, one black and one white, appeared in his palm!
