Demon-Slaying King

The True Dragon Emperor's reverse scale had always been a supreme treasure,

Futu Yun had only persuaded the True Dragon Emperor to part with it by offering a large number of reptilian divine beast corpses in exchange.

With the True Dragon Emperor's reverse scale and the Martial Ancestor's Azure Dragon origin, when Futu Yun fused the two and integrated them into his body,

terrifying energy fluctuations unexpectedly began gathering high above the nine heavens.

Clusters of black thunderclouds containing destructive power slowly took shape there.

Heaven and earth suddenly rumbled, and the previously bright sky instantly darkened.

Even the spiritual energy between heaven and earth sensed the terrifying aura and fled this region in all directions.

Countless spirit beasts trembled and let out miserable howls.

The Black Divine Lightning Tribulation was undoubtedly an exceedingly terrifying existence to all spirit beasts.

Throughout their long cultivation, they yearned for this lightning tribulation that could transform them completely to descend,

yet they also harbored bone-deep fear toward it.

It was a force of destruction truly born of heaven and earth.

That mass of Black Divine Lightning clouds was like ink dropped into clear water, spreading at an unbelievable speed.

In the blink of an eye, the dark clouds covered the entirety of Futuo Continent!

One moment, the sky had been clear and bright; the next, it was filled with dark clouds.

Everyone seemed to have fallen into night, yet the Black Divine Lightning clouds were still spreading at breakneck speed!

After ten breaths, the Black Divine Lightning clouds had shrouded the entire Futu Archipelago.

After the time it took to burn an incense stick, the thunderclouds had covered the entire Great Thousand World.

The vast lands of the Great Thousand World were plunged into darkness.

Some elderly people muttered prayers toward the sky, begging the gods not to unleash their wrath.

And directly beneath those terrifying Black Divine Lightning clouds stood Futu Yun.

Over this period, Futu Yun had seen quite a few Heavenly Sovereign Tribulations triggered when Earthly Sovereigns broke through to become Heavenly Sovereigns.

Yet those Heavenly Sovereign Tribulations could not even fill a small region of a Lower Plane.

How could they compare to the endless black clouds before him, which had directly covered the entire Great Thousand World?

The power of the heavenly tribulation he would face next was easy to imagine!

"Wait, the entire Great Thousand World?" Futu Yun was stunned as well.

He remembered that the present Great Thousand World was only half the size it had been in ancient times.

Although the Primordial War had driven back the Extraterrestrial Evil Clan's invasion,

the Great Thousand World itself had also suffered devastating losses. It had no strength left to reclaim its lost territories and could only retreat to defend the remaining continents.

Moreover, the Extraterrestrial Evil Clan possessed extremely strange abilities. Once they died, their bodies would melt into corpse qi.

After this corpse qi spread, even the spiritual energy between heaven and earth would be corroded and polluted, no longer able to be absorbed and refined.

One of the core reasons the Great Thousand World could become a gathering place for countless Lower Planes

was that it possessed the high-level power known as spiritual energy.

It was not difficult to imagine what a crushing blow it would be if most regions of the Great Thousand World lost their spiritual energy.

The Extraterrestrial Evil Clan's vicious scheme was to completely eradicate all cultivators of the Great Thousand World at the root.

A Great Thousand World without spiritual energy could never be a match for the Extraterrestrial Evil Clan.

By then, the entire Great Thousand World would likely fall under the Extraterrestrial Evil Clan's control.

And the Great Thousand World's cultivators, stripped of spiritual energy, would lose their power and be left at the mercy of others.

At that thought, Futu Yun's lips curved upward. He suddenly decided not to undergo the tribulation on Futuo Continent.

Though this place was relatively safe, and he had the Ancestral Pagoda to protect him.

The next moment, silver light flashed, and Futu Yun appeared in the other half of the Great Thousand World controlled by the Extraterrestrial Evil Clan.

The Black Divine Lightning Tribulation, which had yet to fully take shape, seemed to sense his intent as well.

The black clouds filling the sky suddenly churned, and a terrifying might of heaven and earth abruptly enveloped the surroundings.

Ever more violent lightning power frantically gathered within the thunderclouds.

The aura of destruction made one's scalp tingle, while the pressure of heaven and earth swept across all things.

The Extraterrestrial Evil Clan members all raised their heads to look at the sky, their eyes filled with terror. Their entire bodies shook as they trembled uncontrollably!

They only felt the vast heavenly might bearing down upon them, as though some great terror was about to descend.

They unconsciously knelt on the ground, shivering, while some immediately turned and fled.

Futu Yun's lips curled slightly as he let out a sinister laugh. "Please enjoy this lightning tribulation set meal."

The thunderclouds were violently torn apart, and every sound in heaven and earth froze at that instant.

A massive bolt of black divine lightning, carrying world-destroying power, crashed down from the sky and struck fiercely at Futu Yun.

In the next instant, Futu Yun's body was swallowed by the Black Divine Lightning.

Yet soon, a dragon claw formed from Black Divine Lightning stretched out from the thunder mist and tore sharply.

The dragon claw ripped that bolt of Black Divine Lightning to pieces;

the dragon head formed from Black Divine Lightning let out an earth-shaking roar toward the Extraterrestrial Evil Clan!

This Black Divine Lightning Tribulation had originally been a vital trial on the path of spirit beast evolution.

Its power increased alongside the strength of the one undergoing the tribulation.

Thus, countless powerful spirit beasts had perished beneath lightning tribulations.

After all, the higher one's cultivation, the stronger the lightning tribulation. Even forcibly raising one's strength in advance was useless.

The power of the tribulation encountered would only rise accordingly.

Moreover, Black Divine Lightning was especially hostile toward interference from outside forces.

Even if a spirit beast had powerful elders protecting it, it was useless. Only blood-related humans could lend assistance.

But what surrounded Futu Yun at this moment could hardly be called "blood-related humans."

They were clearly a group of Extraterrestrial Evil Clan members whose auras were utterly opposed to his, even utterly incompatible with this world!

How could this be ordinary interference from external forces?

As a result, the power of the Black Divine Lightning Futu Yun had to face increased by more than a thousandfold.

Massive bolts of black divine lightning now came crashing down in overwhelming numbers.

Every single bolt was aimed directly at the thunder dragon Futu Yun had become.

The Divine Soul Stage allowed one to refine the souls of countless beasts.

Yet with the abilities of that realm, one could at most use spiritual energy to manifest spirit beast souls.

It was absolutely impossible to directly transform into a true spirit beast.

At the Fusion Heaven Realm, one could transform one's body into a spirit beast, yet even though Futu Yun had reached the Heaven Transformation Realm, he could not do so.

Because his spirit beast was Hu She's Netherworld Heart Demon Thunder. Its essence was still lightning rather than a serpent form.

Even after cultivating the Dragon Soul Thunder Spirit, he could not complete the transformation.

But now, with the aid of the Black Divine Lightning, he had achieved a true "dragon transformation":

It was not the Dragon Soul Thunder Spirit that transformed into a dragon. He himself had turned into a thunder dragon formed from Black Divine Lightning!

Any Extraterrestrial Evil Clan member touched by the thunder dragon was instantly blasted into ash, vanishing without a trace at the slightest gust of wind.

The Extraterrestrial Evil Clan screamed as they scattered and fled.

They had never seen such a terrifying scene in their lives.

Yet whenever an Extraterrestrial Evil Clan member was swallowed by the thunder dragon, the Black Divine Lightning covering the dragon's body dissipated by a fraction.

And the Black Divine Lightning clouds assumed that an external force was helping Futu Yun undergo the tribulation.

Thus, the power of the Black Divine Lightning increased even further, as though the valve on its power had been completely opened.

Dense Black Divine Lightning poured down like a waterfall.

The sea of lightning swallowed the thunder dragon Futu Yun had become,

and also swallowed every Extraterrestrial Evil Clan member nearby.

Futu Yun thought for a moment, then suddenly smiled and took out the Great Thousand Palace's Demon-Slaying Command.

Under his gaze, the Demon-Slaying Command remained still for a moment.

Then it abruptly shook, and golden light burst forth from within.

The Demon-Slaying Command began flowing with radiant golden light.

The words "High-Rank Demon-Slayer" at the bottom of the command disappeared.

In their place were three characters that radiated golden light and imposing majesty: "Demon-Slaying King!"
