Slay the culprit! Mythical Treasure Chest!

"Human, being able to withstand thirty percent of my power is enough for you to be proud."

The middle head's voice carried a hint of mockery, "But the game should end now."

The next second.

Its six pairs of bone wings fully unfurled.

Dark red scales stood on end, the wolf head on the left gathered blood-colored energy, the compound-eye head on the right shimmered with spatial fluctuations, and the giant mouth in the middle opened once again, clearly preparing to launch an even stronger attack!

White Night wiped the blood from the corner of his mouth, his eyes sharp as a hawk's.

He knew he had fallen into a disadvantage, but the fighting spirit within him grew even more intense.

"End? Not necessarily!"

His figure suddenly vanished from where he stood.

With Wind Whisper Blessing and Storm Dance stacked, his speed reached its limit, allowing him to circle behind the demon like a ghost, his demon blade whistling through the air as he stabbed at the gap in its back armor.

"Clang!"

The demon blade struck the scales, leaving only a white mark. The demon swiped back with a claw; White Night barely dodged it, but his shoulder was grazed by the force of the strike, instantly becoming a bloody mess.

The demon sneered, pressed forward, and launched a fierce assault on White Night!

Bang! Boom—!

Intense combat shockwaves rang out incessantly.

Amidst the fierce battle, the stained glass of the church shattered completely.

The holy statue was split in two, the ground was covered in ravines and craters, and the air was filled with the stench of blood and burning!

White Night's attacks were like a torrential storm, yet they could never break through the demon's defense.

Meanwhile, the demon's bizarre skills emerged one after another, sometimes using sound waves to rattle his internal organs, sometimes using toxins to erode his meridians, and sometimes using spatial power to disrupt his movements!

After dozens of rounds, White Night was covered in wounds, his breathing ragged.

The demon, however, remained at ease, though the rotation speed of its three heads had slowed slightly.

"Human, your resilience exceeds my expectations."

The middle head's voice carried a bit more gravity, "If I were to give you time to grow, you might truly be able to threaten me, but I don't have time to play with you now..."

White Night suddenly grinned, a cold glint flashing in his eyes: "Thank you for being my sparring partner, but I don't have time to play with you anymore either!"

The next second.

The energy and life essence within his body fused instantly, a dense blood-red light shot into the sky, and the light in the entire church was dyed crimson!

"Soul Devouring Annihilation Flying Sword!"

A blood-soul flying sword with an astonishing aura condensed into form.

The soul patterns on the sword twisted like living things, emitting an aura that made even heaven and earth tremble!

The demon's three heads simultaneously revealed expressions of terror; a tremor originating from the depths of its soul made its hair stand on end!

It roared, its six pairs of bone wings snapping shut to form a dark red shield, while the blood-colored energy spewed from the left wolf head and the spatial barrier deployed by the right compound-eye head overlapped in layers.

"Impossible! How could you possibly possess this kind of power!"

Whoosh!

The next second.

The Soul Devouring Annihilation Flying Sword ignored the layers of defense, piercing through all barriers like a hot knife through butter, instantly transfixing the demon's body!

Pfft!

The demon's three heads froze simultaneously, its body rapidly collapsing under the scorching power of the blood soul, eventually exploding into a cloud of blood mist!

White Night leaned on his demon blade, gasping for breath.

Just as he breathed a sigh of relief, the next moment, he saw the blood mist re-condensing in the air!

Two seconds later.

The demon's body reappeared!

It was missing its right compound-eye head, three pairs of bone wings were broken, its aura had withered significantly, and the eyes of the remaining two heads burned with towering rage!

"You have angered me! I will..."

Before it could finish its threat, White Night didn't say a word and unleashed his ultimate skill again.

Another blood-soul flying sword tore through the air, even faster than before!

Seeing this, the demon's face was filled with disbelief; it flapped its remaining bone wings frantically, trying to dodge, but it was too late.

"No—!"

A shrill roar echoed through the church, and the demon exploded into blood mist once again.

This time, White Night narrowed his eyes, not letting his guard down, his inner energy already poised for action.

Sure enough, the blood mist condensed again; only the middle head of the demon remained, floating in the air, its aura so weak it could dissipate at any moment.

Just as it tried to open its eyes, White Night's ultimate skill had already descended.

Boom—!

The Soul Devouring Annihilation Flying Sword struck the demon's head dead center, causing it to explode into a cloud of blood mist for the third time!

This time, the blood mist did not condense again, and a wisp of black smoke slowly dissipated into the air.

The inside and outside of the church finally returned to peace.

Only White Night's heavy gasps and the sound of falling debris from the walls could be heard from time to time.

...

Inside and outside the church, the dust and smoke gradually settled.

The stench of blood and corrosion that permeated the air also faded away with the demon's complete annihilation.

White Night stood firm, leaning on the eternal demon blade.

The Healing Aura within his body began to circulate wildly, golden light flowing like a warm stream through his limbs and bones.

The wounds on his body healed at a visible rate; as his flesh squirmed, the deep, bone-revealing gashes slowly closed, leaving only faint bloodstains.

His exhausted body was revitalized, and his HP was rapidly restored under the effect of the aura.

He let out a long sigh, his tensed nerves finally relaxing.

The fierce battle with the demon just now had almost drained all his energy.

Immediately after.

White Night took out several bottles of starlight spirit dew from his backpack; these were the few bottles Lin Leer had taken out after the trade contract was concluded.

The crystal-clear blue potion bottles shimmered in the dim church.

He pulled out the stoppers and downed three bottles in succession.

The cool liquid slid down his throat, instantly turning into pure mana that flowed throughout his body.

His previously empty mana bar filled up at an astonishing speed.

With three bottles of potion consumed, his mana had recovered to its peak state!

Even his spirit felt refreshed.

"The effect of this starlight spirit dew is truly formidable; it is absolutely a necessity!"

White Night shook the empty bottles in his hand and smiled with satisfaction.

In the blink of an eye.

White Night's condition had already recovered to its peak!

The energy within his body surged endlessly, and the eternal demon blade hummed softly in his hand, as if cheering for the victory just now!

Just at this moment.

The Game System notification rang in his mind, the golden text appearing even more dazzling than ever before:

【Player 'White Night', you have killed the Demon God Follower -- Three-Headed Demon, and successfully completed the hidden quest!】

【You have received the quest reward: Mysterious Treasure Chest (Mythical Grade) * 1!】

"Hidden quest? Holy crap! So that demon just now wasn't actually part of the quest content!?"

"I knew it! With such high difficulty, how could other professionals possibly complete a third-turn quest!"

Upon hearing the notification, White Night was stunned for a moment, then his face revealed unconcealable joy.

Immediately after.

With a thought, he opened his backpack space.

The next second.

A treasure chest that was pitch black all over, with intricate golden patterns carved on its surface, appeared in his hand.

This treasure chest emitted a faint pressure, and mysterious light flowed between the patterns; just holding it in his hand, he could feel the terrifying energy contained within!

"Mythical Grade treasure chest... This is my first time getting one!"

"This really is a pleasant surprise!"

White Night's eyes glittered with excitement.

This was a chest far more precious than an Epic Grade treasure chest; the rewards inside would absolutely be extraordinary!

Without the slightest hesitation, he pressed his fingers onto the lock of the treasure chest and injected a bit of his internal energy.

Click—!

After a soft click, the treasure chest opened in response!
