The moment the dark shield shattered, a powerful dark aura gushed out from the altar, sweeping towards Lin Fan and the others like a black tide. Lin Fan's eyes were resolute, and without hesitation, he cast a spiritual barrier to protect them. However, this dark aura contained a powerful corrosive force, constantly eroding the spiritual barrier, causing it to flicker.

"Everyone be careful, this dark force is extremely powerful. Don't resist it head-on. Find its flaws first!" Lin Fan shouted loudly, his voice still clearly audible amid the whistling sound of the dark aura.

The disciples nodded in agreement and cast their own spells, attempting to find a glimmer of hope amidst the surging darkness. Ye Yu formed hand seals, and a Holy Spirit Lotus blossomed above her head, radiating a dazzling light. The holy light clashed with the dark aura, creating a sizzling sound. Leng Feng and Yan Yi led the melee disciples, blades in hand, vigilantly observing their surroundings, ready to respond to any danger.

Through their efforts, they gradually discovered that while this dark aura was powerful, there seemed to be some patterns in its flow. Lin Fan concentrated, carefully observing the flow of the dark aura. He discovered that every once in a while, the dark aura would briefly stagnate in a corner of the altar.

"Now! Attack that corner of the altar!" Lin Fan seized the opportunity and gave an order, taking the lead in unleashing the Holy Spirit Demon-Breaking Sword. A ray of white spiritual power pierced through the darkness and rushed towards the corner of the altar.

The disciples responded one after another, casting various spells like raindrops on the corners of the altar. Under the combined attack of everyone, the altar trembled violently, and the surge of dark energy also slowed down.

But this was only temporary. The Dark Altar quickly recovered and unleashed an even more intense dark force. This time, the dark force transformed into various dark creatures, which pounced on Lin Fan and the others with bared fangs and claws.

There are giant dark beasts with huge bodies and sharp fangs, and every step they take on the ground can cause a vibration; there are also dark ghosts that are like ghosts and extremely fast, they shuttle among the crowd, launching sudden attacks from time to time, making it difficult to guard against; there are also some dark slime monsters that exude a foul smell, and wherever they go, the ground is corroded into large pits.

"Don't panic, fight on your own, and support each other!" Lin Fan shouted his instructions to his disciples as he battled a giant dark beast. He unleashed his Phantom Spirit Killing Step, nimbly dodging the beast's attacks, his spiritual sword wielding a continuous blow to its vital points.

Ye Yu controlled the Holy Light Lotus, forming a holy defensive circle around her, dispelling the approaching dark ghosts. At the same time, she also released a stream of Holy Light power from time to time to support other disciples in trouble.

Leng Feng and Yan Yi led their melee disciples in a desperate struggle against the dark slime monster. Using nimble movements and tacit coordination, they dodged the monster's attacks and sought opportunities to deliver fatal blows. Leng Feng's spear was like a dragon emerging from the sea, each thrust slicing away a fragment of the dark slime monster's limbs. Yan Yi's broadsword, with its powerful force and heft, could cleave the slime monster in two with a single blow.

However, the dark creatures were too numerous, and Lin Fan and his companions gradually fell into a difficult battle. Just when everyone felt powerless, Lin Fan suddenly remembered the five artifacts they had collected earlier.

"Gathering the power of the artifacts may be able to resist these dark creatures!" Lin Fan shouted.

Upon hearing this, the disciples took out their own artifacts and placed them around the group in specific positions. Lin Fan concentrated his spiritual energy, guiding the power of the five artifacts to connect with each other, forming a massive divine shield.

The artifact shield radiated a dazzling array of light, keeping the dark creatures at bay. Under the artifact's power, the dark creatures' attacks gradually weakened. They lingered and roared outside the shield, unable to break through this powerful defense.

"We can't keep passively defending like this. We must take the initiative and destroy the Dark Altar!" Lin Fan said with a firm look in his eyes.

He began studying the Dark Altar's structure within the shield, trying to find a way to completely destroy it. After careful observation and reflection, Lin Fan discovered that the Dark Altar's energy source seemed to be connected to a dark spring deep underground. If he could sever the connection between this dark spring and the altar, perhaps he could destroy it.

"I need a few disciples to go deep underground with me to find the source of darkness. The rest of the disciples will stay here to defend the shield and not slack off at all!" Lin Fan selected Ye Yu, Leng Feng, Yan Yi and several stronger disciples, and prepared to go deep underground together.

The group followed the edge of the dark altar and found an entrance leading underground. A thick, dark aura filled the air, like a passage to hell. Lin Fan took a deep breath and stepped through first.

The underground passage was narrow and winding, with strange runes flickering on the surrounding walls, occasionally releasing waves of dark power. Lin Fan and the others moved forward cautiously, constantly alert to possible danger.

After traveling through the passage for a while, they finally arrived at a vast underground cavern. In the center of the cavern, a black spring gurgled forth. This was the Fountain of Darkness. The Fountain of Darkness emanated a powerful dark force, shrouding the entire cavern in darkness.

"This is it. Everyone, be careful. The power of this source of darkness is extremely strong. We must find a way to cut off its connection with the altar as soon as possible." Lin Fan said.

Everyone began to search for clues in the cave, and suddenly, Ye Yu found some strange patterns carved on the cave wall. These patterns seemed to be related to the connection between the source of darkness and the dark altar.

Lin Fan and the others gathered around, carefully studying the patterns. After some effort, they finally understood their meaning. It turned out that to sever the connection between the source of darkness and the altar, they needed to set up a special formation around the cave and activate it with powerful spiritual energy.

"Without further delay, let's start setting up the formation!" Lin Fan said.

The disciples sprang into action, following the instructions on the pattern and setting up a formation around the cave. Once the formation was complete, Lin Fan and the others concentrated their spiritual energy and began injecting it into the formation.

As spiritual energy was injected, the formation gradually lit up, and lines of spiritual energy connected to each other, forming a complex spiritual energy network. When the spiritual energy network was fully formed, a powerful suction force came from the formation, and began to extract the power of the source of darkness.

Sensing danger, the source of darkness began to struggle violently, releasing even more intense dark power in an attempt to break free from the formation's constraints. Lin Fan and the others gritted their teeth, striving to maintain the formation's operation and engaging in a fierce battle with the source of darkness.

During this battle, Lin Fan and the others' spiritual energy was constantly depleted, but they never gave up. Finally, with their persistence, the power of the Dark Source was gradually drained away, and the connection with the Dark Altar was successfully severed.

At this time, the dark altar on the ground lost its energy source and cracks began to appear. The dark creatures also dissipated because they lost the support of power.

Lin Fan and the others quickly returned to the surface. Seeing the Dark Altar already teetering on the brink of collapse, they seized the opportunity and launched an all-out attack. Under their combined force, the Dark Altar finally collapsed with a bang, reduced to a pile of rubble.

With the destruction of the Dark Altar, the dark forces within the ancient city gradually dissipated, and sunlight once again shone upon the land. Lin Fan and the others stood wearily amidst the ruins, but their faces were filled with the joy of victory.

However, Lin Fan knew that this was only a temporary victory in their struggle against the forces of darkness. Somewhere in the world of immortal cultivation, an even more powerful force of darkness was quietly brewing.

After returning to Wuzong, Lin Fan detailed his experience to the other disciples and elders within the sect, commending those who had performed exceptionally well in battle. He also began to reorganize and redeploy the sect's cultivation resources, strengthening the disciples' training and preparing for future threats from dark forces.

At the Immortal Cultivation Alliance meeting, Lin Fan briefed the various sect representatives on their battle in the ancient city and the latest developments regarding the dark forces. The sect representatives expressed admiration for the bravery of Lin Fan and his companions, but also expressed concern for the future.

"We can't just sit there and wait for death. We must strengthen cooperation and communication among the various factions in the alliance and jointly explore ways to fight against the forces of darkness," said Lin Fan.

Representatives from various sects nodded in agreement. At the meeting, they decided to establish a dedicated research group, with Lin Fan as its leader, to study the characteristics of the dark forces and methods for breaking them. Furthermore, each sect would regularly organize joint drills among their disciples to improve their combat rapport and collaborative capabilities.

In the days that followed, Lin Fan led the research team into intense research. They collected a vast amount of information and ancient texts related to the dark forces, conducting in-depth analysis and research. They also communicated with some of the hermit masters and independent cultivators in the world of immortal cultivation, hoping to gain some unique insights into the dark forces from them.

After a period of research, they discovered that the dark power seemed to be related to a mysterious space crack. This space crack was hidden in every corner of the world of immortal cultivation, releasing dark power from time to time, thus causing various disasters.

"If we can find these space cracks and seal them, we may be able to effectively curb the spread of dark forces." Lin Fan put forward his idea.

The members of the research team discussed and analyzed this idea and decided that although the task was difficult, it was worth a try. Thus, they began a large-scale search operation in the world of immortal cultivation, looking for those mysterious space cracks.

During their search, Lin Fan and his companions encountered various difficulties and dangers. Some dimensional rifts were hidden in extremely secluded locations, requiring them to decipher numerous traps and formations to find them. Others were guarded by powerful dark forces, forcing anyone who approached them to be violently attacked. Still others were located in dangerous areas, such as deep within volcanoes and undersea abysses, presenting significant challenges to their search.

However, Lin Fan and his companions were not intimidated by these difficulties and dangers. With their unwavering faith and tenacious perseverance, they overcame difficulties time and time again and found the locations of some space cracks.

Lin Fan and his companions tried various methods to seal the discovered spatial rifts. They harnessed the power of divine artifacts, deployed powerful formations, and drew upon the forces of nature to engage in fierce battles against the dark forces within the spatial rifts.

During an operation to seal a spatial rift, Lin Fan and his companions arrived at an ancient mountain range. Hidden within this mountain range was a massive spatial rift, from which a powerful dark force continuously surged, shrouding everything around it in darkness.

Lin Fan and his companions set up a massive defensive formation around the mountain to prevent the spread of the dark forces. Then, they began preparing for the ritual to seal the spatial rift.

They placed five artifacts around the spatial rift, arranging them in a specific orientation and order. Then, Lin Fan led his disciples in injecting spiritual energy into the artifacts, activating their sealing power.

As spiritual energy was infused into the artifact, it gradually began to glow, forming a massive sealing halo. The halo slowly approached the spatial rift, attempting to envelop it.

However, the dark force within the spatial rift sensed the danger and began to resist frantically, unleashing black lightning bolts that attacked the seal aura and Lin Fan and the others.

Lin Fan and the others quickly cast spells to resist. Ye Yu controlled the Holy Light Lotus, releasing holy light to disperse the black lightning one by one; Leng Feng and Yan Yi led the disciples to form a spiritual shield to protect the artifact and Lin Fan and the others who were being infused with spiritual power.

In this fierce confrontation, Lin Fan and the others consumed a huge amount of spiritual energy, but they never gave up. Finally, with their persistence, the sealing aura successfully enveloped the spatial rift, gradually sealing away the dark forces within.

As time went on, Lin Fan and his companions successfully sealed several spatial rifts, and the dark forces in the world of immortal cultivation were contained to a certain extent. However, they knew that this was far from enough, and there were still more spatial rifts waiting for them to discover and seal.

By chance, Lin Fan obtained an important clue about the source of the dark power. It is said that in the far north of the world of immortal cultivation, there is a mysterious island covered in ice and snow, which hides the secret of the source of the dark power.

Lin Fan decided to lead his disciples to the Far North to explore this mysterious island. They embarked on a long and arduous journey, crossing frigid ice fields, turbulent glaciers, and dangerous ice storms.

Finally, they arrived at the mysterious island. The island was filled with a strong dark aura, and the cold air seemed to be mixed with particles of dark power.

Lin Fan and his companions carefully explored the island and discovered an ancient castle. The castle's gates were tightly closed, and the area was filled with various traps and mechanisms.

Lin Fan led his disciples to decipher the traps and enter the castle. The castle was dark and damp, with strange portraits hanging on the walls. The characters in the portraits seemed to tell a dark story.
