Mortal: Starting with the Falling Cloud Sect, I proved my Dao through gacha pulls.

Passing through the silver vortex, a huge blood pool and nine white jade pillars came into Su Mu's view first.

"Such pure demonic energy!"

Su Mu was secretly alarmed. The demonic energy here was so dense that it was almost tangible, and its source was deep within the blood pool.

He first looked at the nine stone pillars, and saw that the pillars were covered with chain marks and human-shaped imprints, clearly indicating that some living beings had been imprisoned here.

But now the chains are broken, the marks are faded, and there is nothing left.

After briefly exploring the hall, Su Mu slowly walked towards the central blood pool.

At the edge of the blood pool sat a skeleton as white as jade, with several pill bottles, a silver token, and an ancient bell broken into several pieces scattered around it.

Su Mu cautiously approached, flicking out a wisp of strange fire to test it. The skeleton, which had endured countless years, was scorched by the flames, but no remnant soul dissipated, yet it remained completely unharmed.

"Just what level of cultivation did this person reach back then?"

Su Mu was surprised. He picked up the scattered pill bottle, but it was empty. The pills were long gone.

He took the fragments of the ancient bell into his hand, feeling that they were unusually heavy and made of extraordinary material. However, they were now devoid of spiritual light and power, and must have been remnants left after the self-destruction.

He shook his head and reached out to take the intact silver token.

The front of this token is engraved with an ancient sword, and the back is inscribed with a line of small characters:

"Xuanweizi suppresses the ancient demon here."

"Ancient demons... so they were from the ancient demon war era." Su Mu muttered to himself, "This senior Xuanweizi was able to suppress ancient demons single-handedly, he was indeed a great power from ancient times."

After putting away the token, Su Mu's gaze fell on the center of the blood pool.

Dense demonic energy surged and swirled in the pool, and a blood-red crystal-like skull floated quietly in the center of the pool, with a curved horn on its forehead. It was clearly the remains of an ancient demon that had been suppressed.

"Could there be any remnants of ancient demonic souls here?"

Just to be on the safe side, Su Mu released two streams of strange fire, which swept through every corner of the hall, indiscriminately burning and purifying it.

A full half hour passed without any unusual activity in the hall, and he finally breathed a sigh of relief.

The next moment, a glint flashed in Su Mu's eyes, and he activated the Nine Heavens Profound Jade Bottle with all his might.

Suddenly, the bottle emitted a brilliant golden light, and a supreme yang energy that suppressed all evil swept through the entire hall!

As the bottle slightly opened, a terrifying suction force suddenly erupted, causing the blood pool to surge upwards and the billowing demonic energy to rush into the bottle like a whale sucking water. The blood-red ancient demon skull was also forcibly pulled up and swallowed into the bottle in an instant.

As soon as the demonic energy entered the bottle, it was crushed and dissolved by the supreme yang energy, like ice and snow meeting the blazing sun, instantly transforming into a torrent of pure primordial power that frantically nourished the magical artifact.

The Nine Heavens Jade Bottle hummed and trembled, its aura growing increasingly powerful.

Once the demonic energy within the hall was completely devoured, the Nine Heavens Jade Bottle trembled slightly and fell back into Su Mu's palm. The aura of the magic weapon had clearly become more refined, and its power had quietly increased significantly.

"It's like nurturing something carefully for decades, which is an unexpected bonus."

Su Mu smiled slightly, nodded in satisfaction, and then turned his gaze to the bottom of the dried-up blood pool.

After the blood pool was drained, seven emerald green stones were revealed at the bottom of the pool. They varied in size, with the largest being the size of a fist and the rest being the size of an egg.

The stone is entirely green, with wisps of black smoke flowing inside, exuding a chilling and sinister aura.

"This is... a Ghost Stone?!"

Su Mu took the stones into his palm, examined them briefly, and immediately recognized their origin, a look of joy spreading across his face.

This stone is born in places where demonic energy and filth gather. Wearing it can ward off illusions and illusions, and it is especially effective against mazes of evil spirits.

If combined with magical artifacts from the ghost or demonic paths, the foundation of the artifact can be greatly strengthened.

"nice one!"

Su Mu gave a low praise and casually put the Nether Soul Stone into his World Ring, intending to refine it into a bracelet in the future, or directly integrate it into the White Bone Demon Banner to enhance its power.

He scanned his surroundings again to make sure he hadn't missed anything before walking back to the remains of Xuanweizi.

After a thorough search, no martial arts techniques or secret methods were found to have been passed down or left behind.

Su Mu sighed softly, took out soil and stones from his world ring, carefully buried the white jade skeleton, bowed to show his respect, and then turned and left the stone hall.

After leaving the hall, he removed all the formations and slightly erased any traces. With a leap, he broke through the water and emerged.

"It's time to head to Biling Island."

He took out the Qiankun Disc, locked onto the coordinates of Thunder Sky Island, and with a flicker, disappeared directly from the void.

A month later.

Su Mu has been flying north from Thunder Sky Island for over a month, and the number of cultivators along the way is gradually decreasing, with even high-level demonic beasts becoming increasingly rare.

He finally arrived at the waters of Biling Island, and from dozens of miles away, he could already see the outline of that enormous island.

This island was vast and boundless, the largest island he had ever seen in the open sea, its size in no way inferior to Tianxing City in the inland sea, which made him secretly startled.

As he flew closer, he could see that there were several towering peaks on the island, their cliffs steep and sheer, standing alone and piercing the clouds.

But when Su Mu actually set foot on the island, his brows furrowed slightly.

The entire giant island was barren, a desolate gray-white landscape, and the world was deathly silent, devoid of any spiritual energy.

Anyone who looks at it would assume that this place is an abandoned island without any spiritual veins.

"That's right. This island is so conspicuous. If there were any spiritual energy here, the spiritual vein would probably have been discovered long ago."

Su Mu shook his head, extending his divine sense to its limit to examine the area carefully.

Apart from a few low-level monster lairs, there was no trace of spiritual veins within the range of divine sense.

"It seems I'll have to search slowly."

He smiled helplessly. He only knew that the original text recorded that there was a top-grade spiritual vein hidden in this place, but he did not know its exact location. Now he could only explore it himself.

He had considered taking the entire giant island into his world ring, but with his current cultivation level, he was powerless to move such a massive island. He could only use the most clumsy yet safest method to explore it inch by inch.

With a flick of his finger, Su Mu sent over 100,000 ghost-patterned moths flying out. With a thought, the moths scattered and searched the entire island.

"You guys shouldn't just sit around either."

With a flick of his wrist, he released over ten thousand more Netherworld Dust Insects, allowing these spirit insects to burrow underground and search for traces of mineral veins, relying on their extraordinary sensitivity to spiritual energy.

He himself, wielding the magical artifact, dug holes and explored the earth all over the island, truly experiencing the joys of being a miner.

......

Six years have passed in the blink of an eye.

Su Mu was sitting cross-legged on an open space on Biling Island, drawing upon the power of the Taiyin Star to temper himself, intending to cultivate the Crimson Bright Nine Heavens Diagram to the Purple Mansion realm as soon as possible.

Suddenly, a thought stirred within him, and a strange sensation originating from the Netherworld Dust Insect quietly entered his mind.

"Finally found it."

Su Mu chuckled, immediately stopped his cultivation, stood up, and rode his escape light straight towards the direction from which he sensed the movement.

After six long years of searching, even he was getting impatient, but this time he finally found traces of that top-grade spiritual vein.

Guided by his inner thoughts, Su Mu arrived at a majestic stone peak.

This peak is one of the highest peaks on Biling Island. It looks ordinary on the outside, but it has a hidden world inside.
