As night deepened, the various factions from the Lingxu Market stealthily made their way towards the valley where the mysterious forces were entrenched, like phantoms. Moonlight bathed them, illuminating their resolute faces. Lin Yang led the group, his sharp eyes constantly alert to any movement around him.

As the group approached the valley, the disciples of the Linghe Merchant Guild, skilled in Qimen Dunjia (a form of divination), immediately sprang into action. They dispersed, carefully observing the flow of the illusory mist, rapidly forming hand seals and chanting incantations. With each infusion of spiritual energy, the illusory mist began to exhibit strange fluctuations, and the seemingly seamless fog gradually revealed faint, intermittent passages.

"Quickly, proceed according to the markings!" the elder leading the group whispered. The group cautiously advanced along the passage, the mist on either side churning like a tangible force, seemingly intent on swallowing any intruders. The sword cultivators of the Spirit Sword Sect gripped their swords tightly, their blades gleaming coldly, ready to respond to any unexpected situation.

Just as the group ventured deeper into the illusory mist, a sharp whistling sound suddenly echoed from within. Immediately afterward, countless black arrows shot out from the mist, raining down upon them. "Defend!" Lin Yang commanded. The members of the Linghe Merchant Guild swiftly erected spiritual energy shields, their multicolored light instantly illuminating the area and blocking the black arrows. The arrows struck the shields, clanging and clattering, sending sparks flying.

"It seems we've been discovered. Prepare for battle!" The elder of the Spirit Sword Sect said solemnly, waving his hand. The sword cultivators immediately formed a sword formation. The sword formation resembled a blooming sword flower, with sword energy crisscrossing and dispelling some of the surrounding mist.

Meanwhile, the disciples of Wanbao Pavilion were not idle either. They all unleashed their magical treasures. One disciple's pagoda shone brightly, and beams of golden light shot out from it, heading towards the mist. Wherever the light touched, the black arrows melted away, and the mysterious man's exclamation could be faintly heard.

As the battle commenced, the mysterious figures emerging from the illusory mist gradually materialized. Clad in black robes and wielding various bizarre weapons, their eyes revealed a fierce and resolute intent. "Kill!" the sword cultivators of the Spirit Sword Sect roared in unison, their sword formation swirling like a whirlwind towards the mysterious figures. The sword cultivators' figures weaved through the mist, their sword energy like rainbows, instantly clashing with the mysterious figures. For a moment, shouts of battle and the clash of spells intertwined, echoing throughout the valley.

Lin Yang knew he had to break through the illusionary mist as soon as possible, otherwise a protracted battle would be disadvantageous. He circulated his spiritual power, and the power of the mysterious light points surged through his meridians like a torrent. Then, he unleashed a sword technique that fused with the power of space, tearing open a massive spatial rift in the mist. The powerful suction force pulled the surrounding mysterious figures into it. The mysterious figures let out screams as their figures dissipated within the spatial rift.

Led by Lin Yang, the group finally broke through the illusory mist and entered the valley. The sight before them made them gasp. The valley was filled with various defensive arrays, their light shimmering like dazzling stars. Under the protection of these arrays, the mysterious figure was methodically organizing a counterattack.

"Attack the array's core!" Lin Yang shouted. The disciples of Wanbao Pavilion immediately locked onto the array's core and unleashed their powerful magical artifacts. One after another, magical artifacts imbued with immense spiritual power flew towards the array's core, their light dazzling and their explosions deafening.

The sword cultivators of the Spirit Sword Sect engaged in fierce combat with the mysterious figure, buying time for the Myriad Treasures Pavilion's attack. The sword cultivators' sword formations were ever-changing, sometimes like dragons emerging from the sea, sometimes like tigers descending the mountain, making it difficult for the mysterious figure to defend himself.

However, the mysterious figures were not to be outdone. Their leader stood on high ground, waving a black banner and directing his men. The mysterious figures unleashed powerful spells, beams of black light shooting towards the group. The members of the Spirit Harmony Guild struggled to maintain their defensive shields, which trembled violently under the powerful attacks, their light flickering erratically.

The battle reached its climax, with both sides suffering heavy casualties. However, the various factions in the Lingxu Market were determined to fight to the death, knowing that retreat meant certain doom. Lin Yang, observing the battle, understood that the crucial moment was approaching. He quickly contacted the assault team, preparing for a final, all-out attack to destroy the core of the mysterious force in one fell swoop.
