Lin Feng charged towards the guardian beast like a blue lightning bolt. His entire spiritual power was concentrated on the ice halberd, radiating a chilling aura. The guardian beast sensed Lin Feng's intention and tried to stop its attack and turn to defend, but Lin Feng was too fast. Just as the guardian beast was about to make a move, the ice halberd had already pierced its abdomen.

"Pfft!" The ice halberd successfully pierced the gap in the scales on the guardian beast's abdomen. Lin Feng twisted it forcefully, and the guardian beast let out a shrill scream. Black blood gushed out like a fountain, splashing onto the surrounding ground and corroding black pits. The guardian beast writhed in agony, frantically whipping its tail, trying to shake Lin Feng off.

Lin Feng gripped the Ice Halberd tightly, bracing his feet against the guardian beast to prevent himself from being thrown off. At this moment, Xuan Feng and the others seized the opportunity of the guardian beast's injury and distraction, launching their strongest attacks. Xuan Feng unleashed "Storm Vortex," a massive vortex of wind engulfing the guardian beast, countless wind blades spinning wildly within, slicing through its body. Su Ran conjured several enormous ice pillars, shooting them towards the guardian beast from different directions. The woman in white raised her hands high, chanting, "The Flame God Descends!" A massive, blazing sun appeared in the sky, crashing down upon the guardian beast. The female general and the Blood Shadow Sect woman were equally relentless; their figures flashed, their weapons raining down on the guardian beast.

Under the combined attack of the group, the guardian beast gradually succumbed. Its body was riddled with holes, and black blood flowed all over the ground. Finally, the guardian beast let out a low, mournful cry and collapsed to the ground. Everyone breathed a sigh of relief upon seeing the fallen beast, but no one let their guard down. After all, in this mysterious underground palace, danger could strike again at any moment.

Lin Feng pulled the Ice Halberd from the guardian beast, looked at the enormous corpse before him, and said, "This guardian beast is so powerful, the 'Spiritual Firmament Scripture' must be nearby." The others nodded and continued their search within the palace. Just then, a light suddenly shone from the far end of the palace, growing stronger and stronger until it was almost blinding.

As the light gradually faded, a stone platform radiating multicolored light appeared before everyone's eyes. On the platform lay an ancient book, its cover inscribed with three ancient characters—"Lingxiao Canon." Lin Feng and the others were overjoyed; they had finally found the legendary "Lingxiao Sacred Canon."

However, just as Lin Feng stepped forward to pick up the sacred scripture, a sinister laugh echoed from all directions. "Hmph, you think you can obtain the 'Spiritual Firmament Sacred Scripture' so easily? Everything is under our control." As the voice faded, a group of men in black emerged from the darkness, surrounding Lin Feng and his companions. Leading them was none other than the shadowy figure who had been rescued by the black-robed men earlier. Although the shadowy figure was pale, the resentment in his eyes remained undiminished.

"So it's you, a remnant of the Shadow Cult." Lin Feng glared at the shadowy figure, gripping his ice halberd tightly. The shadowy figure sneered and said, "That's right. From the moment you stepped into the former site of the Lingxiao Sect, you fell into our trap. The 'Lingxiao Sacred Scripture' is something our sect is determined to obtain. None of you will leave here alive today."

Xuanfeng looked at the men in black around him and sneered, "You? I let you escape before, but I won't give you another chance this time." The shadowy figure said disdainfully, "I was careless last time, but this time you won't escape." With that, he waved his hand, and the men in black rushed towards Lin Feng and the others.

Lin Feng was the first to engage, his ice halberd whirling through the air with incredible power. Each strike carried immense ice-based spiritual energy, instantly freezing several men in black into solid blocks. Xuan Feng was equally formidable, manipulating wind-based spiritual energy to toss and turn the men in black, then unleashing wind blades that sliced ​​through their bodies like razor-sharp scalpels. Su Ran, meanwhile, continuously cast ice spells from the rear, alternating between ice shards and ice walls, protecting her companions while inflicting heavy damage on the enemy. The white-clad woman's fire magic was even more ferocious, engulfing the men in black in raging flames, their screams echoing everywhere. The female general and the Blood Shadow Sect women, with their agile movements, weaved through the ranks of the men in black, their weapons targeting the weakest points in their defenses.

However, the men in black were numerous and fearless, surging towards the group wave after wave. Lin Feng and his companions gradually found themselves in a fierce battle, their strength waning. Just as they were beginning to give up, suddenly, a mysterious sword aura swept in from the palace entrance, instantly killing dozens of men in black. The group looked on in astonishment to see a mysterious swordsman dressed in white slowly entering the palace.

The mysterious swordsman wielded a longsword, its blade radiating a faint glow. His movements were light and graceful.

A mysterious swordsman, wielding a longsword that emitted a faint glow, stepped lightly into the palace, each step seeming to resonate with the hearts of everyone present. Sword energy crisscrossed around him, instantly shredding any approaching men in black. Lin Feng and the others were both surprised and delighted; in this perilous moment, the appearance of the mysterious swordsman was like a savior descending.

The mysterious swordsman, his face cold and his eyes sharp as lightning, swept his gaze over the surrounding men in black and said indifferently, "A bunch of rabble, yet you dare to act so presumptuously here." With that, he flashed into the crowd of men in black like a white phantom. His longsword flashed, unleashing a torrent of sword energy, and the men in black fell one after another, none able to withstand a single blow from his blade.

Upon seeing this, the figure in black's expression changed drastically. He hadn't expected such a mysterious expert to appear at this crucial moment. But he was unwilling to give up, and he gritted his teeth and shouted, "All of you, attack! Ignore him, take back the 'Spiritual Scripture' first!" Upon receiving the order, some of the men in black continued to besiege Lin Feng and the others, while the others rushed towards the "Spiritual Scripture" on the stone platform without regard for anything else.

Lin Feng watched the mysterious swordsman move through the black-clad crowd as if it were nothing, secretly marveling at his skill. But the situation was critical, and he had no time to think further. He gripped his ice halberd again and fought alongside his companions. Xuan Feng unleashed his wind-elemental spiritual power to its fullest extent, creating a raging storm within the palace, scattering the black-clad figures charging towards the "Lingxiao Sacred Scripture." Su Ran continuously cast ice spells from the rear, providing cover for her companions while also inflicting significant damage on the black-clad figures. The white-clad woman's fire spells combined with Xuan Feng's raging winds to create a sea of ​​fire, causing the black-clad figures to cry out in agony. The female general and the Blood Shadow Sect woman seized their opportunities to launch fatal blows against those black-clad figures whose defenses had been breached by the spells.

The mysterious swordsman fought with increasing ferocity among the men in black. His swordsmanship was exquisite, each strike precise and deadly, killing countless men in black wherever his sword energy passed. However, the number of men in black was simply overwhelming, like an endless tide. Although the mysterious swordsman was powerful, he began to struggle after a while.

Lin Feng noticed the mysterious swordsman's condition and knew that everyone needed to unite to escape their predicament. So he shouted, "Listen up, everyone! Let's cooperate with this senior and concentrate our strength to repel these men in black!" Everyone nodded in agreement.

Xuanfeng unleashed "Wind Prison," trapping some of the men in black within. Then, Lin Feng seized the opportunity, activating "Ice Explosion." His ice halberd pierced the ground, and centered on the Wind Prison, a powerful burst of ice-based spiritual energy instantly froze all the trapped men in black into blocks of ice. The ice then shattered, turning the men in black into dust. Su Ran continuously used "Ice Mirror Reflection," reflecting the white-clad woman's fire magic onto even more men in black. In an instant, flames soared into the sky within the palace, and screams of agony echoed throughout.

The mysterious swordsman secretly admired Lin Feng and his companions' seamless teamwork. Taking advantage of the moment when the black-clad men were thrown off balance by their combined attack, he unleashed his strongest sword technique—"A Thousand Waves of Sword Shadows." His figure vanished instantly, replaced by countless sword energies surging towards the black-clad men like ocean waves. Each sword energy contained immense power, which the black-clad men were utterly unable to withstand, and they were all cut down.

Seeing his men suffer heavy losses under the combined attack of the mysterious swordsman and Lin Feng, the shadowy figure was filled with anxiety and rage. He knew that if things continued this way, not only would they fail to seize the "Lingxiao Sacred Scripture," but he and his men would likely perish. Therefore, he decided to take a desperate gamble and intervene personally.

A sinister aura emanated from the shadowy figure. A black dagger appeared in his hand, its surface shimmering with an eerie light. He chanted incantations, and with each incantation, the surrounding space seemed to distort. The corpses of the dead men in black slowly rose to their feet, their eyes flashing with an eerie red light, and lunged at Lin Feng and the others once more.

"This is bad! This is an evil secret technique of the Shadow Cult, capable of controlling corpses!" Lin Feng said gravely. The mysterious swordsman frowned and said, "Hmph, I'd like to see just how powerful this evil technique is." With that, he swung his longsword again, unleashing sword energy towards the corpses. However, these corpses seemed to feel no pain; even after being severed by the sword energy, they continued to lunge towards the group.

Lin Feng and his companions were locked in a fierce battle with the corpses. Although they continuously eliminated the corpses, new ones kept rising, leaving them utterly exhausted. Just as everyone was beginning to despair, the Blood Shadow Sect woman suddenly discovered that the corpses' movements seemed to be controlled by a shadowy figure. Whenever the shadowy figure made a move, the corpses' actions would change accordingly.

"Listen up, everyone! Ignore the corpses for now and focus all your attacks on the shadowy figure. Once we defeat him, these corpses will fall!" the Blood Shadow Sect woman shouted. Hearing this, everyone's eyes lit up, and they rushed towards the shadowy figure.
