Horsehoof City.

Countless Demonic Cultivators arrived, the demonic mist surged, and the Heaven's Vault was in turmoil.

The Peak Master of Vastness Peak, Li Shiyi, stood suspended in the sky above Horsehoof City.

The Vast Righteous Domain unfolded, the Vast Righteousness Qi fluctuating up and down.

The black Taibai Sword had long left his hand, transforming into a black rainbow, shuttling back and forth in the space before him.

The Taibai Sword moved at an astonishing speed, its sharp blade tearing through Demonic Cultivators like paper, leaving countless gore in its wake.

Even a mere brush past the enemy, like a dragonfly skimming water, caused those Demonic Cultivators to fall as if struck by an ancient fierce beast, their chests collapsing and bones shattering as they spewed blood while being flung backward.

Various demons of different forms fell from the sky like rain, creating a series of heavy impacts as they hit the ground.

The Taibai Sword swept across, claiming the lives of countless Demonic Cultivators.

"A mere Fourth Tribulation Realm dares to stand in the way?" The commander of the allied forces, Tufei Demon Venerable, watched this scene with cold detachment, utterly indifferent.

Indeed, Sword Cultivators see realms as meaningless, but the premise requires a solid foundation of cultivation.

In his eyes, the Peak Master of Vastness Peak fell far short of that level.

"Let me personally send you on your way and end this battle!" Tufei Demon Venerable shouted resolutely, striking out aggressively.

Tufei Demon Venerable, with a robust physique wrapped in black mist and his face covered in scales.

He was very confident, making bold moves, stirring up bursts of black wind.

The black wind then swept into a hurricane, howling upward.

Vanish Wind Divine Demon Body.

This was the Divine Demon Body practiced by Tufei Demon Venerable.

Tufei Demon Venerable moved with extreme speed, with the hurricane, he quickly crossed over the demon army, charging directly at the Peak Master of Vastness Peak, intending to crush him in a direct confrontation.

The tide formed by Demonic Cultivators, augmented by this hurricane, accelerated once again, directly targeting the Sword Sect cultivators.

The battle had been ongoing for some time, yet the leading Demon Lord of the demons had never truly intervened.

Unexpectedly, once he struck, it was with thunderous might, as if intending to swallow the team of over 800 Sword Cultivators led by Li Shiyi in a single gulp.

Witnessing this, the expression on Li Shiyi's face grew increasingly grave.

Even one as powerful and confident as he did not dare claim a method to withstand Tufei Demon Venerable's formidable offensive.

Tufei Demon Venerable possessed high-ranking Demon Lord combat power as well.

To understand why Tigerhead City and Bullhorn City dared to face down with just seven hundred Sword Cultivators, beyond the fact that each of the seven hundred was a fighter against hundreds, there was a crucial condition: the leaders, Gu Qiu and Ning Fengchen, both possessed exceptionally mighty sword techniques.

The strength of each of them rivaled that of high-ranking Demon Lords.

This allowed them to stand as unyielding pillars under the onslaught of the demonic tide, withstanding the most intense frontal assault, and preventing Eastern Qii Demon Lord and Taixuan Demon Lord from picking them off one by one.

The critical issue currently was that Gu Qiu was a Seventh Tribulation Realm cultivator, and Ning Fengchen was an Eighth Tribulation Realm cultivator, which granted them combat power on par with high-ranking Demon Lords.

But Li Shiyi, even having ascended three realms in a single day recently, was only at the Fourth Tribulation Realm now.

The Fourth Tribulation Realm was insufficient for him to possess the foundation to confront a high-ranking Demon Lord.

In truth, if given more time for him to verify what he learned in this life, he would very likely achieve unprecedented heights.

With continuous battles since defending the city, Li Shiyi felt he already touched upon some opportunities—the cultivation path of Sword Cultivators has always been one to nurture through battle.

But now, the demonic tide had arrived.

If he continued to suppress his realm, focusing on future heights, then the fellow Sword Cultivators around him would surely be crushed under the demonic tide.

He could not allow such a thing to happen.

He could not linger in the Fourth Tribulation Realm.

He must break through immediately.

Thus, Li Shiyi recalled the Taibai Sword.

He silently withdrew all his aura back into his body.

He appeared like an ordinary person.

Yet, the charging Tufei Demon Venerable suddenly felt an immense danger, his skin crawling, and he immediately halted his offensive stride.

Bang!

Suddenly and without warning, in the dim sky, a massive purple lightning bolt descended from the sky, striking at Li Shiyi.

This lightning bolt, with a diameter of several dozen feet, pierced through heaven and earth.

The brilliant light resembled a purple mountain ridge descending from the sky, massive and terrifying, pressing so heavily that it was hard to breathe.

The sky suddenly changed color.

The terrifying lightning instantly brewed, transforming into a vast purple ocean, pouring down and completely engulfing Li Shiyi.

The lightning sea was violent, one wave after another; the horrifying fluctuations terrified the Demonic Cultivators.

"The Fifth Nine Heavenly Tribulation…" Tufei Demon Venerable's expression suddenly became serious, inwardly relieved that he had halted his offensive just in time, lest he be caught in the tribulation's range—it would have been unbearable.

Over here, the black Taibai Sword in Li Shiyi's hand was bursting with magnificent fireworks.

Countless Sword Lights rose, unleashing immense Sword Intent, colliding with the countless descending lightning strikes, stirring up terrifying torrents of Heaven and Earth Element Qi.

Roaring continued to sound, the brilliant lightning and Sword Light completely engulfed the figure of the Peak Master of Vastness Peak, making it impossible for onlookers to see the true scene within.

The lightning seemed never-ending, connecting heaven and earth, vast and boundless, like the Nine Heavens Milky Way hanging upside down, or countless massive stars falling.

The void was stretched to its limit, the blinding lightning filled every inch of space, deterring anyone from stepping a single step into the lightning pool.

The demonic army, forced by the laws of the heavenly tribulation, had to halt their advance and retreat.

The Sword Sect cultivators also retreated substantially.

Thus, what should have been a raucous battlefield presented a strangely eerie scene.

The two sides, like the red and black sides in a chess game, used the lightning pool of the heavenly tribulation summoned by Li Shiyi as a river boundary, confronting each other from across the river, clearly distinguishing friend from foe.

It could be said that the Peak Master of Vastness Peak was not only undergoing a tribulation but also using the power of the heavenly tribulation to hold back the demon army, astonishing everyone.

This was something only the Peak Master of Vastness Peak could achieve.

Because in today's Human Race, only he could actively summon the heavenly tribulation at will.

The other Eighth Realm cultivators could only faintly sense when the heavenly tribulation was about to arrive.

And such perception was quite vague, not to the point of specifying a particular time or even a precise day.

The thunder roared like a tide, seemingly endless.

After passing the Fifty-Nine Heavenly Tribulation, the Vastness Peak Master did not rest for a moment, and once again initiated the Sixty-Nine Heavenly Tribulation.

The two tribulations were almost seamlessly connected, making it seem as though the thunderstorm had no end.

A vast purple fog covered the world.

The scene was so shocking that even from a distance, it was terrifying, leaving one unable to imagine the immense pressure Li Shiyi was under as he faced the heavenly tribulation head-on.

And indeed, this was the case.

At the level of the Fifty-Nine and Sixty-Nine Heavenly Tribulation, even the Vastness Peak Master, who treated heavenly tribulations as nothing, could no longer handle it as effortlessly as before.

He stood at the center of the tribulation, bearing unimaginably severe damage.

Though severely wounded, his spirit soared, showing no sign of defeat, instead, he continued to advance with his head held high.

Struggle against the heavens, a joy beyond compare.

Once again, a tide of thunder rolled down fiercely, burying him below.

But at the same time, a dense power of heaven and earth descended with the tribulation, merging into his body, nourishing his physical form, bringing transformation and elevation.

Tufei Demon Venerable's gaze was grim, helplessly watching as Li Shiyi continually broke through, daring not to intervene.

Doing so would not only be futile but also subject him to the vast heavenly tribulation's impact, leading to certain demise.

Another wave of heavenly tribulation arrived, with ten thousand fathoms of purple light piercing through heaven and earth, like a mighty dragon soaring skywards.

Both sides, human and demon, held their breath, silently observing.

The endless thunder, the blazing divine light, made the dark sky as bright as daylight, radiant and dazzling.

Boom!

Finally, with a resonant hum, the sea of purple disappeared, the thunder dissipated, and heaven and earth returned to calm in an instant, as if nothing had ever occurred.

As the thunder ended and all calmed, Li Shiyi's figure emerged from the purple sea and the sword light.

Tufei Demon Venerable quickly glanced over.

There stood Li Shiyi, quietly, his physique shining with a precious glow, his eyes clear, like a banished immortal descending to the mortal world.

"He is now... the Seventh Tribulation Realm?"

Tufei Demon Venerable's brow twitched, sensing immense pressure, utterly shocked.

Fourth Tribulation Realm advancing to the Seventh Tribulation Realm.

Since Yi River Platform ascended three realms in a day, the Vastness Peak Master once again ascended three realms in a day.

"What of the Seventh Tribulation Realm?" Tufei Demon Venerable's face darkened, trembling with rage.

"Today, you must die!"

Seventh Tribulation Realm, but still not the Eighth Realm?

He was a Ninth Grade Demonic Cultivator, after all!

Why should he fear Li Shiyi?

Surrounding Tufei Demon Venerable, tens of thousands of black hurricanes formed at this moment, resembling spears, and roared intimidatingly as they shot towards the Vastness Peak Master.

This scene was terrifying, a manifestation of a great divine skill.

Simultaneously, the demonic army, which had just halted, surged forward once more.

"Vast Righteousness Qi…" Just after breaking through and reaching peak again, the Vastness Peak Master felt tranquil, perceiving the abundant righteousness qi within.

Ning Fengchen was first at killing, Gu Qiu first in sword qi, Yu Canghai first in sword arrays, Xue Wujian first in explosive power.

He, Li Shiyi, had never managed to be first in any of these, but he opened a new, unprecedented Sword Dao uniquely his own:

Vast Righteousness Qi.

"Go."

Li Shiyi silently, with a thought, vast righteousness qi filled and flowed over the sword.

Then, the Taibai Sword flew across the sky.

As the sword emerged, harmonious notes resounded throughout heaven and earth.

It was as if heaven and earth exhaled a breath, blowing over the land, causing countless apertures in the earth to roar.

The apertures differed — some like noses, some like mouths, some like ears, some like rectangular holes in pillars, some like enclosed fences, some like deep pools, some like shallow ponds, hence the sounds they made were also different.

Like the rushing sound of water, like the keen sound of arrows, like loud shouts, like quiet breathing, like loud cries, like wailing, echoing deeply in the valleys, like birds calling and twittering, truly as if front was singing woefully and back was howling along.

The gentle breeze carried a faint harmony, while the long wind led to great reverberations, abrupt fierce storm ceased, myriad apertures fell silent.

This breath exhaled by heaven and earth was wind, and everything swayed with its passage.

At this moment, the Vastness Peak Master also exhaled a breath, bringing with it a breeze.

What breath?

Vast Righteousness Qi.

What wind?

The Delightful Wind.

Where the Delightful Wind passed, initially joined by harmonious notes of heaven, then followed by complete silence.

Thousands of black tornadoes perished.

The mighty demonic tide, in this moment, was also briefly emptied.

The Vastness Peak Master's long sleeves fluttered, his robe billowed elegantly.

The Taibai Sword, now returning, was caught in his hand.

Calmly, he looked ahead, locking eyes with Tufei Demon Venerable.

"Come." he softly spoke to Tufei Demon Venerable, provocatively.

On that day at Yi River Platform, when his cultivation had not yet returned, he wielded the three-foot Delightful Wind.

And now at the Seventh Tribulation, was his former pinnacle of cultivation.

Therefore, his vast righteousness qi had entirely returned.

The Vastness Peak Master at this time was truly…

One point of vast righteousness, a thousand miles of Delightful Wind.
