"A seventh-level restriction, with my current array formation cultivation, it's impossible to break..." Yuan Ming sighed silently, feeling a heavy heart.

He also understood why the Black Bear King and the Flame Wolf King were lying in ambush for the Daluo Sect; it was likely that these two Demon Kings couldn't open the door either and could only guard outside the palace.

As Yuan Ming was pondering the forbidden breaking method, the battlefield not far away saw a change in its situation.

The Black Bear King forced back Master Tantai with a single move, then suddenly pounded his chest, letting out a sky-shattering roar. His body rapidly expanded, transforming in an instant into a hundred-zhang tall black fur bear with silver patterns all over.

"This is the Sky Demon True Body! Looks like the Black Bear King has unleashed his True Fire!" Seeing this scene, Yuan Ming immediately distanced himself from the Xi He Palace's gate.

High-level demon clans inherently dual cultivate their Dharma Bodies, and after reaching Level 6, they face two paths: one is to refine demonic power like human cultivators condensing a Dharma Manifestation.

The second path is to abandon the cultivation of demonic power and focus on honing the physical body, condensing the Sky Demon True Body.

The Sky Demon True Body possesses unparalleled power, surpassing those of the same level in Dharma Manifestation; however, its weakness is evident, becoming an easy target after enlarging, and not utilized unless in a life or death crisis.

Master Tantai's face turned solemn instantly, flicking the duster, causing the surrounding nature's spiritual energy to rush furiously. An imposing Dharma Body dressed in a Daoist robe manifested in an instant, stepping forward and single-handedly lifting Emperor Yan's Mysterious Fire Tripod.

As man and demon were about to engage in a full-force battle, the void above Xi He Palace rippled, revealing a silver-white extravagant flying car from thin air.

Yuan Ming noticed the situation and immediately turned to look at the flying car, seeing spirit light gleaming upon it, with a majestic aura akin to Emperor Yan's Mysterious Fire Tripod, clearly also a Great Perfection Spirit Treasure.

Four figures were standing on the flying car, precisely Sima Changqin and three Black Demons.

"Qin Demon!" The Black Bear King was startled, his advancing body abruptly halted.

The Flame Wolf King and other demon clans changed their expressions, ceasing their struggle against Yang Fan, Gan Wenqing, and others, retreating to the side.

The Daluo Sect members were nearly at their limit, and seeing Sima Changqin arrive, they were naturally overjoyed.

"Fellow Daoist Tantai, it's unexpected that you've arrived ahead of us," Sima Changqin remarked from the flying car, looking at Master Tantai.

"Lord Qinmo, you've caught us off guard with our state," Master Tantai withdrew his Dharma Body, smiling wryly.

"Fellow Daoist Tantai, your words are too heavy. These demon clans bully with numbers; why bother dwelling on it?" Sima Changqin chuckled, then turned to the Black Bear King and Flame Wolf King.

The two Demon Kings' expressions subtly changed, focusing their vigilance.

"The legend says the Ten Thousand Demon Country descends from the Ancient Sky Demon Royal Court, where the royal court hosted the Bear Demon Saint, Greedy Wolf Demon Saint, Sky Roc, Coiling Serpent, and Vinesprout—five great demon saints, each with cultivation as vast as the sky and earth, renowned across the Chuyun Realm. Seeing you two, you seem to inherit from the Bear Demon Saint and Greedy Wolf Demon Saint. Today, I'll have a lesson," Sima Changqin raised his hand and the purple-black ancient zither on his back flew out, landing in front of him.

This zither is over four feet long, wide in front and narrow at the back, appearing exquisite and refined.

The Black Bear King and Flame Wolf King's faces changed, immediately leading everyone to fly far away.

Sima Changqin paid no heed, gently placing his hands on the zither, casually plucking a melody that flowed like water, reaching into everyone's ears.

The Black Bear King had already fled to afar, even casting treasures for protective body, yet the zither sound still clearly penetrated their ears.

In an instant, the demon clan of Ten Thousand Demon Country witnessed numerous enchanting demonesses appear before them, dancing gracefully to the melody, their flying garments carrying an eerie magic that seized their souls, stirring their emotions.

"Be careful! This is one of Sima Changqin's ten enchanted musical themes, the Heavenly Demon Charm. Close your eyes and focus your mind!" yelled the Black Bear King.

The group of demons hurriedly shut their eyes, calming their minds.

However, even though they blocked their ears and closed their eyes, the soul-seizing zither sound continued to serenade, as if playing within their hearts.

All Level 5 demon beasts soon had their minds crazed, swaying to the movements of the demonesses.

Both the Black Bear King and Flame Wolf King were drenched in sweat, demonic power surging wildly, yet barely maintaining their sanity.

"Worth being among the Five Great Demon Kings, they can withstand Lord Qinmo's Heavenly Demon Charm, but unfortunately, it ends here," Wu Li sneered, then looked at the nearby Black Demon woman with a high ponytail.

This woman raised her hand, drawing across the void, and silky red spirit light surged from her fingertip, resonating with the surrounding nature's spiritual energy, causing four red talismans to appear from thin air, layer upon layer of intricate runes appeared.

"Void Formation! Moreover, judging from the complexity of these talismans, it's at least a Level 5 Talisman—this woman is a talisman master?" Yuan Ming, hiding below, watched with a shocked expression.

The Black Demon woman pointed with her fingers, and the four talismans suddenly glowed brightly, transforming into four large crimson arrow shadows, shooting out.

The red arrow shadows, burning with crimson flames, carved shallow marks in the void as they tracked towards the two demons, Black Bear and Flame Wolf.

The Black Bear King and Flame Wolf King sensed the impending crisis, yet they were utterly incapable of resistance, watching wide-eyed as the arrow shadows approached.

At this moment, a massive fox tail phantom swept over, hitting the four crimson arrow shadows.

Boom, boom, boom!

The four crimson arrow shadows exploded, producing massive mushroom clouds in mid-air, the surrounding void issued explosive sounds, wobbling and twisting.

"A Level 5 Talisman couldn't possibly have such power; could it be a Level 6 Talisman?" Yuan Ming was genuinely astounded and then suppressed the surprise, looking towards the white fox tail's location.

"Lord Qin Demon, with your esteemed status, why bother with my subordinates? If you wish to duel, you may seek me." In the location of the white fox tail, the void rippled once more, revealing Wu Yu's figure, looking at Sima Changqin as he spoke calmly.

Behind Wu Yu, light flashed, and Xuan Ye and the Electric Roc King appeared simultaneously.

"Since Chang Qin arrived here, he has never encountered a decent opponent. Since Her Majesty wishes to spar, I am happy to oblige," Sima Changqin said with a smile, as the sound of the zither flowed once more.

This time, the sound of the zither was completely different from before, urgent and fervent.

In an instant, the fire attribute spirit qi in the surroundings became agitated, rapidly gathering at one point, and in the blink of an eye, it condensed into a giant blazing sword a hundred feet long, slashing straight towards Wu Yu.

Flames continuously erupted from the giant sword, producing bursts of explosive sounds, carrying an incredibly terrifying heat. As it swung, it seemed as if even the void was burnt away, making it impossible to see its descending trajectory.

Yuan Ming, hiding to the side, immediately saw that this sword was not merely a simple aggregation of spiritual power, but contained the true intent of flames, bearing a power capable of burning everything in the world.

Even if it were him facing this sword, it would not be easy to withstand.

"Dutian Fierce Fire Song?" Wu Yu's expression slightly changed. Two white fox tails instantly emerged from behind her, pure white throughout, seemingly containing some kind of divine power.

One of the white fox tails swept towards Xuan Ye and the Electric Roc King, gently pushing them away to avoid any accidental injuries, while the other struck the blazing great sword.

With a loud "boom," the blazing great sword was swept and broken, its remnants thoroughly dispersed.

Sima Changqin's smile did not fade, clearly not surprised by this, as he plucked the zither strings once more.

Red light flashed in mid-air, and four giant swords of flames appeared instantly, just as large as before, each containing the true intent of flames, slashing down towards Wu Yu together.

Wu Yu's expression did not change, merely summoning one more white tail, intertwining to scatter the flaming giant swords.

However, before she could catch her breath, red light flashed around, and sixteen gigantic fire swords appeared, continuing to rush towards Wu Yu, sealing off all space for evasion.

Finally, Wu Yu was no longer at ease, and directly crossed her arms, forming a spell with each hand.

Demonic power surged madly from her body, and six white fox tails emerged, wrapping her body completely, making it look like a giant white light cocoon.

The sixteen giant swords slashed onto the fox tail light cocoon, instantly causing flames to fly wildly, white light to flash intensely, and explosive sounds to merge into one, making the ears of the spectators hum so much that they couldn't hear anything else, nor see what was happening inside.

Yuan Ming's eyes flickered with golden light, penetrating the sky full of fiery white glow to see Wu Yu's current state.

The white light cocoon formed by the fox tails was mostly slashed apart, but the remaining fox tails still protected Wu Yu.

"Her Majesty, be careful,"

Sima Changqin's voice rang out again, and without caring whether Wu Yu could hear, he continued to drive his mana, his fingers dancing on the ancient zither, producing shadow after shadow.

In an instant, more and more giant swords of flame appeared out of nowhere in the sky, one became ten, ten became a hundred…

In the span of two breaths, the densely packed giant swords of flame covered the sky, numbering in the hundreds.

These flaming giant swords circled the white light cocoon, forming a sword array, swirling and cutting without pattern, yet quietly closing in towards the center.

The surrounding temperature rose sharply, and a series of crackling sounds echoed in the air, causing everyone to simultaneously feel a difficulty in breathing, as the moisture in their bodies evaporated rapidly, seeming as if they would turn into desiccated corpses in the next moment.

Everyone's expressions changed, quickly retreating backwards, not daring to linger for even a moment.

And this, was merely the power of the residual ripples of Sima Changqin's spell.

The cultivators could not even imagine how Wu Yu, facing this move directly, must feel. In their eyes, the legendary Ten Thousand Demon Empress was likely in dire danger.

But in the next instant, as if to refute the speculation of the crowd, the white light cocoon surrounded by the red sword light suddenly expanded, and then with a roar, exploded abruptly.

Nine enormous white fox tails, like petals, spun open, piercing the flaming sword array.

The densely packed sword shadows were pierced through, and Wu Yu's form shot out from the sword array, with the nine tails unscathed, still bright and new, exuding a sacred white glow.

The onlookers witnessed this scene, and for a moment, it was as if they saw a white lotus blooming amidst the endless flow of fire, dreamlike and enchanting, leaving one in awe.

While everyone was engrossed in Wu Yu's majestic presence, Sima Changqin gently chuckled, proactively stepping down from the silver flying car, and bowed towards Wu Yu.

"The Ten Thousand Demon Empress indeed lives up to her reputation. It appears the Heavenly Fox Bloodline has been fully activated, my compliments," he said with a smile.

"Not at all, it is Fellow Daoist Qinmo's superior skills. Were it not for holding back a bit, I fear I would have already been defeated," Wu Yu slightly bowed in return, also giving a salute.

The two exchanged smiles, as if the sparring match had never occurred.

Many of the onlookers were left confused, scratching their heads.

But Yuan Ming saw clearly from the side, realizing that the bout was merely Sima Changqin's way of probing Wu Yu's abilities, to ascertain her strength.

Now that his goal was achieved, he immediately ceased the exchange.

As for Wu Yu, it seemed she was unwilling to engage in conflict with Sima Changqin, welcoming his withdrawal with a smile.
