666. Chapter 664: The Mystery of the Dark Night Mine

"Even if it's the strongest defense, I will shatter you!"

He clenched his teeth, poured in spiritual power once more, and the sword's light flickered.

Su Liyan watched the cave entrance closely from the side; seeing Lu Yuan's abnormal state, she understood his resolve.

She unhesitatingly fused the cold jade ice shard into her body, and the Ice Crystal Long Whip instantly radiated a chilling aura.

"I'll lend you a hand!"

She activated the power of the treasure, and the whip in her hand began to dance.

Lu Yuan felt Su Liyan's support and the boost of power; his resolve became unshakable.

Lu Yuan and Su Liyan coordinated seamlessly, launching continuous attacks on the formation at the cave entrance.

Time quietly passed several hours; both consumed vast amounts of spiritual power, yet they never gave up attacking.

The defensive formation gradually weakened; as it was about to be exhausted, Su Liyan suddenly stopped moving.

"Someone's coming!"

She glanced warily toward the rear of the cave.

Lu Yuan also sensed something amiss; he warily scanned his surroundings.

Suddenly, a chilling icy aura came from deep within the cave.

"Demonic cultivator! How dare they come here!"

Their figures swiftly turned, simultaneously invoking immortal arts to prepare for the enemy attack.

Just as they finished battle preparations, a strange demonic cultivator flashed out, attempting to sneak into the cave.

However, before he could react, Su Liyan's Ice Crystal Long Whip pierced his chest in a single strike.

Blood spurted out; the demonic cultivator screamed and collapsed, unable to rise.

Lu Yuan and Su Liyan exhaled in relief; without mercy, they immediately disposed of the demonic cultivator's corpse.

Such a place cannot retain even a trace that might arouse suspicion.

Seeing the defensive power at the cave entrance about to vanish completely, they exchanged a glance of firm resolve.

At this moment, they knew victory was within reach; as long as they entered the cave's depths, they could find the legendary hidden treasure.

Lu Yuan and Su Liyan entered the cave together in unison; the darkness behind them gradually sealed shut.

The path ahead grew ever deeper and secluded, yet their hearts brimmed with anticipation.

Lu Yuan and Su Liyan proceeded cautiously through the dark cave; the deeper they went, the stronger the pressure in the air became, making it hard to breathe.

An ancient, heavy aura permeated the surroundings, evoking a suffocating feeling.

They slowly followed the cave's interior route, and before them gradually appeared the corpse of a demonic cultivator that had withered for many years.

The corpse's posture was bizarre, its face frozen in an expression of extreme terror.

Lu Yuan's gaze fell on the scattered crystals and jade slips beside the corpse.

He crouched down, examining the crystals and jade slips closely.

The crystals flickered with a faint light, as if containing some special energy.

The jade slips were inscribed with strange, ancient characters.

Lu Yuan took one crystal in hand and gave it a slight turn, instantly feeling a foreign, powerful force assail him.

He was shocked to discover that these crystals were actually blood pearls!

Blood pearls are rare treasures formed by demonic cultivators condensing enemies' blood; they can swiftly boost cultivation, but refining them requires profound demonic arts.

Such treasures have nearly vanished from the immortal realm.

Lu Yuan rubbed the crystal, a hint of thought flickering in his eyes.

He understood that mastering the method to produce these blood pearls would undoubtedly greatly enhance his and his team's strength.

However, before attempting to study the production method from the information recorded on the jade slips, they had a more important task: to find the legendary treasure hidden deep within the cave.

Thus they continued onward.

Lu Yuan and Su Liyan continued deeper into the rear of the cave; those in the darkness gradually adapted to this stifling, oppressive atmosphere.

They stepped on dust, proceeding cautiously.

Moonlight poured through cracks in the cave ceiling, outlining the mysterious, ancient scenery within.

Gradually, a vast, desolate open-pit mine unfolded before Lu Yuan and Su Liyan's eyes.

The two exchanged a sensory stimulus—deeply inhaling the rust-like smell permeating the air.

"Is this also one of the methods the demonic cultivators left to guard the treasure?" Su Liyan asked softly.

Lu Yuan nodded, then his gaze swept over the reddish gleam scattered on the ground.

In stark contrast to the surrounding dim yellow gloom, those mysterious ore chunks flashing with red luster stood out exceptionally bright.

Immediately, Lu Yuan discovered an ancient, peculiar massive stele erected beside the open-pit mine.

He quickly approached the stele, carefully examining the mysterious and powerful immortal symbols carved all over it.

"This is… Stellar Transformation!"

Lu Yuan could hardly believe his eyes; touching the symbols on the stele, his trembling fingers seemed to convey his inner excitement.

Su Liyan watched Lu Yuan, excited to the point of almost jumping, and smiled faintly.

She knew what this meant for Lu Yuan.

Stellar Transformation is one of the extremely rare and powerful immortal arts in the heavenly court, ranking among the foremost.

Lu Yuan took a deep breath, surveying the silent, unseen cave around him.

Moonlight cast their silhouettes high from the cave roof; he silently resolved to spend the night cultivating here, striving to grasp the essence of the Stellar Transformation immortal art as much as possible.

Time flowed on, night deepened, all was quiet.

In that unbelievable open-pit mine filled with mysterious power, Lu Yuan gradually immersed himself in cultivation.

His body trembled slightly, the thunderfire sword on him released strong electric light, and a thunder-like sound echoed throughout the mine.

Upon returning to Splendid Direction City, Lu Yuan immediately felt a tense atmosphere.

On the streets inside the city, people hurried past, their faces wearing worried expressions, as if some major event were about to happen.

Lu Yuan pushed open the door of Lei Huo Dan Ge, and Su Liyan and Zi Xi'er, who had been waiting for him inside, saw him enter and immediately walked over.

"Lu Yuan, you've finally returned!"

"These past few days, rumors have spread in the city that Mo Di has colluded with the Dragon Clan's crown prince and is secretly plotting a new round of blood sacrifice."

Su Liyan said anxiously.

Lu Yuan furrowed his brow slightly; this news made him understand even more clearly what kind of conspiracy Mo Di hid behind.

"Zi Xi'er, tell me where they are meeting?" Lu Yuan asked.

Zi Xi'er pondered for a moment and said: "According to the news, they will meet at the Magic Dragon Manor and there conduct the blood sacrifice ritual."

Lu Yuan's expression grew grave: "We must quickly gather our forces and head to Magic Dragon Manor to expose their plot before it fully takes shape!"

Su Liyan nodded in agreement, knowing that this was the critical moment and there could be no further delay.

Rain curtains shrouded Heavenly Wind City, thunder boomed, as if foreshadowing the impending turmoil.

Lu Yuan urgently led Su Liyan and Zi Xi'er to the headquarters of the Black Flame Sect. (End of chapter)
