Da Yi's heaven-shaking arrow not only forcefully beat back the arrogant Hell-grade bone dragon, but also forcibly tore a gap in the pitch-black sea of undead.

However, this was merely the beginning.

Just as the members of the Evernight Guild had yet to recover from the shock of Da Yi looking like a Heavenly God descending to the mortal world, the thick darkness above the ruins churned violently.

"Hum——!"

Accompanied by a soul-piercing holy hum, a beam of light, brilliant to the extreme, pierced through the eternal gloom of the Abyss of Mist with the force of a withered tree being crushed.

"That is..." Qin Ming widened his bloodshot eyes and looked up at the sky.

At the center of the beam of light, a figure bathed in endless holy radiance slowly descended.

Six flawless wings of light suddenly spread out behind him, with every feather shimmering with profound Law halos. Holding a great cross sword burning with pure white holy fire, an aura of holiness, majesty, and inviolability instantly swept across the battlefield like a tsunami.

"It's Lord Gabriel!" A Cheng shouted with a hoarse voice, so excited that the dilapidated tower shield in his hand dropped to the ground.

Gabriel did not pause. As he descended, he raised the Holy Light cross sword in his hand high, and spat out emotionless yet extremely majestic syllables from his mouth: "Holy, Purification."

A loud noise echoed——!

In an instant, centered around Gabriel, a ring of visible golden Holy Light ripples spread outward frantically.

For everyone in the Evernight Guild, this light was as warm as spring. Wounds that were originally deep to the bone miraculously began to heal under the illumination of this light, and their depleted mana values were also rapidly recovering.

But for those undead skeletons, this Holy Light was an unadulterated disaster!

"Hiss hiss——!"

"Roar!"

Upon coming into contact with the Holy Light, tens of thousands of undead soldiers erupted into extremely miserable screams.

The dark blue soul fire on their bodies shook violently, resembling lingering snow splashed with boiling oil. A large amount of white smoke rose from the surface of their bones, and then amidst crisp "crack, crack" sounds, they turned into bone powder scattered all over the sky!

In just the time of a single breath, the originally despair-inducing sea of undead was disintegrated by more than half by this vast Holy Light!

Even that skeletal giant dragon in mid-air, having just stabilized its figure, trembled heavily when swept by the aftermath of the Holy Light. The indestructible dragon bones on its surface actually showed signs of melting, emitting an extremely painful howl as it was forced to beat its bone wings and retreat backward.

This overwhelming power gave the members of the Evernight Guild, who had fallen into a desperate situation, a chance to breathe.

"Lord! The Lord has come!"

It was unknown who shouted first in the crowd, and immediately after, the entire surviving team erupted into deafening cheers.

The ecstasy of surviving a desperate situation brought tears to the eyes of these men who had walked on the edge of life and death.

Far away in the underground base of Donghai City, Zhou Huai was simultaneously controlling two top-tier Avatars on two fronts.

"Everyone, immediately pass through the Teleportation Array and exit the ruins!"

Dragging his injured left arm, Qin Ming rushed forward in two steps and shouted loudly: "Moli! How is the situation with the Teleportation Array?"

Beside the Teleportation Array not far away, Moli, covered in dust, gritted her teeth, her staff continuously outputting magic power to stabilize the Formation: "The Formation eye has been reactivated! But the energy is extremely unstable, and we can only teleport one hundred people at a time!"

"Enough!" Qin Ming turned around and sternly ordered all the guild members: "Mages and priests go first! Heavy infantry evacuate last! Do not panic, form a queue, and execute the Lord's command immediately!"

Watching the team below begin to retreat in an orderly manner, the tense string in Zhou Huai's heart relaxed slightly.

But he did not completely lower his guard, controlling Gabriel to hover in mid-air while staring into the depths of the ruins with eyes like torches.

"Where on earth did this undead army pop out from?"

Zhou Huai furrowed his brow, thinking rapidly in his mind.

The Evernight Guild had explored the ruins of the Abyss of Mist more than once.

Although there were many exotic beasts on the outer perimeter, the vast majority were demonic creatures infected by the abyssal aura.

An ancient undead army like this, with a massive scale, complete organization, and even knowledge of tactical Formations, was definitely not an exotic beast species native to the ruins!

What made Zhou Huai feel even more apprehensive was——

The Holy Purification skill he had just released through Gabriel had clearly crushed large patches of skeletons into bone powder, yet the System's prompt tone made no sound at all!

There was no kill prompt!

There was no experience points credited!

This simply did not conform to the System rules of this world!

"Could it be that the skill just restrained them in terms of attributes and scattered their physical forms, but did not truly annihilate them?"

Zhou Huai's intuition told him that things were far trickier than imagined.

Sure enough, just as this thought arose in his mind, sudden changes abruptly occurred on the battlefield below that had been swept by the Holy Light!

"Crack, crack, crack..."

The hair-raising sounds of skeletal friction rang out densely.

Zhou Huai narrowed his eyes, only to see that the undead remains that had originally scattered all over the ground or even turned into bone powder were being pulled by some invisible thread, beginning to violently wriggle and converge on the ground!

In less than ten seconds, those broken bones pieced themselves back together, and dark blue soul fire ignited within their hollow eye sockets!

They emitted wave after wave of silent roars, actually crawling up from the ground and re-converging into a boundless torrent of skeletons, frantically chasing in the direction of the Teleportation Array!

Could even the skills of an SS-rank Holy-type Professional fail to achieve complete annihilation?

Zhou Huai's expression sank completely.

What on earth is the background of these skeletons?

They actually possess the bizarre trait of being immortal and indestructible!

While thinking this, Zhou Huai did not pause his movements in the slightest.

The six wings behind Gabriel vibrated frantically, and a continuous stream of Holy Light transformed into a rain of light all over the sky, pouring down onto those skeletons that had crawled back up.

On the other side, Da Yi, hovering in mid-air, also drew the stellar longbow to its maximum.

"Whoosh, whoosh, whoosh!"

The dense starlight arrow rain fell like shooting stars, each strike capable of piercing the skulls of dozens of skeletons and nailing them dead to the ground.

Relying solely on the two god-like figures of Da Yi and Gabriel, they forcefully constructed an insurmountable firepower defense line in front of the narrow ruins passage, firmly blocking the tens of thousands of undead armies a hundred meters away from the Teleportation Array.

However, Zhou Huai's heart did not relax; instead, it became increasingly heavy.

"Although the individual strength of this skeleton army is not strong, averaging around level thirty or forty, this infinite resurrection mechanism is just too disgusting." Zhou Huai gritted his teeth inwardly within his main body.

Although his two Avatars both possessed terrifying SS-rank destructive power, their mana values were also limited!

Faced with this kind of unkillable and inexhaustible enemy, once the mana value bottomed out, the defense line would collapse! They simply couldn't afford to drag this out!

"We must find a way to cut off the source of their resurrection..."
