Bai Ying remained standing calmly at the bow of the ship, her robes fluttering, her expression as serene as ever. A spiritual light flowed from her fingertips, echoing the defensive array around her, blocking the ferocious attacks of the six black-scaled earth dragons from reaching her.

Those terrifying claw strikes and venomous spits, powerful enough to tear apart Nascent Soul cultivators, couldn't even touch a single hem of her clothing!

Even more terrifying, Bai Ying seemed to think that these dragons were wasting too much of their time by constantly besieging their flying boat, so she actually drew her sword from its sheath.

She lightly raised her hand, and a clear, resonant sword rang out through the valley, as a long, pure white sword was drawn from its sheath.

The cold light emanating from the sword was like moonlight pouring down, dazzling everyone's eyes.

"She...she's going to..." one disciple stammered, unable to finish a sentence, his legs trembling like a leaf. The others stared wide-eyed, their faces filled with horror.

It's already a miracle that she survived the attack by such ferocious beasts, yet this White Fairy still wants to take the initiative to attack?

Wei Ji's face turned deathly pale, and his voice trembled: "Fairy Bai, what...what do you want to do...?"

Before he could finish speaking, Bai Ying lightly flicked the tip of her sword, aiming directly at the vital point of the nearest earth dragon.

Upon seeing this, the earth dragon's scarlet vertical pupils flashed with a hint of mockery, clearly showing that it didn't take this tiny human seriously.

"Of course, we should kill them." Bai Ying's tone was eerily calm.

"Are you insane?" a disciple shouted hysterically. "These are all late-stage Nascent Soul level ferocious beasts! Even if you're strong, you can only handle one at most, and there are twelve of them!"

"If you want to die, go die yourself! Why drag us into this..." Before the other disciple could finish speaking, his eyes suddenly widened.

With a slight turn of her wrist, countless jet-black flame lotuses suddenly bloomed on the sword's edge.

These lotus flowers slowly rotated in the air, each petal shimmering with an eerie purplish-black light, as if they came from the karmic fire of the deepest hell.

The locked-on earth dragon let out a disdainful growl, its thick tail slapping defiantly against the rock wall, sending up a shower of rubble.

But when the first black lotus gently landed on its brow, its scarlet vertical pupils suddenly contracted to the size of pinpoints.

The dragon scales, which were said to be able to withstand a full-force attack from a Nascent Soul cultivator, were silently pierced through like rice paper!

"roar!!!"

The mournful roar of the dragon shook the entire valley violently, and countless spiderweb-like cracks appeared on the cliffs on both sides.

The remaining eleven earth dragons watched in horror as their companion's hundred-foot-long body was being frantically eroded by those eerie black lotuses.

Even more terrifying, the black flames transformed into countless fine, eerie runes within the dragon's body. Each rune twisted as if alive, frantically eroding along the meridians.

Wei Ji's pupils constricted sharply, his entire body feeling as if it had fallen into an ice cave: "This...this is..." His voice was distorted and twisted with extreme horror, "The Flame of Extreme Yin?"

He finally recognized what the black flames were, and his back was instantly soaked with cold sweat.

As the elder guarding the library, he would never mistake the black flames entwined around the white firefly sword.

That was the underground fire recorded in the "Chronicles of the Nine Netherworld Flames," which had burned away the underground flames of three ancient sects. But legend has it that this kind of flame should have disappeared by now... How could it appear here?

"roar!"

The agonizing howl of the hundred-foot-tall earth dragon interrupted his thoughts. The sound didn't seem to come from a living creature; it was more like the lamentations of millions of wronged souls simultaneously in purgatory.

Wei Ji mechanically turned his neck and saw a scene that nearly shattered his Dao heart: the black iron-like scales curled and peeled off in the black flames, revealing the rapidly carbonizing scarlet flesh underneath.

Those scales, which were said to be able to withstand a full-force attack from a Nascent Soul cultivator, were now crumbling layer by layer like dried clay.

Bai Ying's fingers traced the spine of the sword, and the black flames that had been swirling on the blade suddenly erupted, striking straight at the earth dragon's body.

Wei Ji then noticed her sword moves. These moves were exceptionally powerful, with each initial stance carrying a distorted sense of tearing through space, leaving spiderweb-like black cracks wherever the sword blade passed.

"Click"

The sickening sound of bones cracking echoed one after another. The earthworm-like body began to collapse from the inside, like a towering ancient tree hollowed out by borers.

The most horrifying thing was the wounds licked by the black flames; instead of being charred, the flesh was simply reduced to nothingness.

Wei Ji suddenly understood why ancient books said, "The flames of extreme yin burn things without leaving a trace."

This flame devoured not only the physical body, but also existence itself.

As the last coccyx vaporized in the flames, the tip of the white firefly sword lightly flicked it.

The black flames, like rivers flowing into the sea, condensed again into a thin line and disappeared into the sword sheath.

"Is she really only at the late Nascent Soul stage?" someone murmured to themselves.

This question grew wildly in everyone's mind. A normal Nascent Soul cultivator, let alone slaying a thousand-year-old earth dragon equivalent to a Deity Transformation stage cultivator, would be terrified by the dragon's sheer power.

But now...

Bai Ying sheathed her sword and stood there, the remaining black flames on the blade coiling and hissing like living things, as if unwilling to be extinguished. Her gaze swept indifferently over the remaining earth dragons, and the ferocious beasts retreated in unison, their thick claws carving deep furrows in the ground, low growls rumbling in their throats, their eyes filled with fear.

The next moment—

"boom!!"

The earth dragon horde completely collapsed, fleeing frantically in all directions, their heavy bodies crashing through rock walls and kicking up clouds of dust. Just a few breaths ago, they were ferocious and had the cultivators completely surrounded; but now, not a single earth dragon dared to linger in the entire valley.

On the flying boat, you could hear a pin drop.

All the disciples seemed frozen in place, even their breathing stopped. Their eyes widened as they stared intently at the black ash drifting in the air—the last trace of the earth dragon, leaving not even a trace of its remains.

The disciples who had been shouting moments before were now all ashen-faced, their legs trembling as they knelt on the ground. One of them was even trembling uncontrollably, his teeth chattering, his eyes filled with disbelief.

Bai Ying sheathed her sword, turned around, her clothes fluttered lightly, her black hair cascaded down like a waterfall, and her expression remained calm, as if the sword strike just now was merely a casual brush away of dust.

She raised her eyes, her gaze slowly sweeping over the people on the airship, her voice as cold as frost:

"Now, does anyone still have any questions?"

No one answered.

The airship remained deathly silent; even the sound of the wind seemed frozen.

Finally, an elderly monk swallowed hard, bowed deeply, and said in a hoarse voice:

"White Fairy...we...are completely convinced."

His voice seemed to break some kind of seal, and the other cultivators were as if they had just woken up from a dream. They all bowed their heads and paid their respects, no longer daring to show the slightest disrespect.
