While the Lingxu Market actively developed cooperation with various parties and enhanced its own strength, a mysterious letter quietly appeared at the Linghe Chamber of Commerce's intelligence outpost. This letter had no sender, and the envelope was made of a special material, exuding a faint smell of decay, as if it came from some dark and damp corner.

Upon discovering the letter, the guild member responsible for intelligence gathering immediately sensed its unusual nature and swiftly presented it to the guild leader. The leader opened the letter and saw several lines written in a strange black ink: "Fools of the Spirit Ruins Market, do you think you can rest easy after one victory? A true catastrophe is about to befall you. In the dark abyss of the far north, there lies a terrifying power beyond your comprehension. If you wish to stop it, go alone; otherwise, the entire Spirit Ruins Market will perish for your ignorance."

The Chamber of Commerce president's expression turned grave upon reading the letter. He knew this was no ordinary threatening letter; the "Shadow Society" was likely plotting some earth-shattering conspiracy in the dark abyss of the far north. He dared not delay and immediately took the letter to discuss the matter with Lin Yang and the leaders of various factions.

Everyone gathered in the secret chamber of the Linghe Merchant Guild, the atmosphere tense and oppressive. Lin Yang carefully examined the letter, his brows furrowed: "This letter is very likely a conspiracy by the 'Shadow Society,' but we can't ignore it. The dark abyss of the far north ice plains might hold the key to their comeback."

After pondering for a moment, Zhao Wanbao, the head of Wanbaoge Pavilion, said, "Perhaps this is a trap. They want to lure us in so they can launch a new attack on the Lingxu Market. But if we don't go, we might miss the chance to stop their conspiracy."

The elder of the Spirit Sword Sect said with a firm gaze, "Whether it's a trap or not, we must send people to investigate. We cannot allow the 'Shadow Society' to cause trouble in the shadows and threaten the safety of the Spirit Ruins Market and the entire cultivation world."

After a heated discussion, the group decided to first send an elite team to the Dark Abyss in the far north to investigate. The team consisted of elite sword cultivators from the Spirit Sword Sect, disciples from the Myriad Treasures Pavilion skilled in tracking and detection, and experts from the Spirit Harmony Chamber of Commerce proficient in intelligence analysis and the art of divination.

Before setting off, Wanbaoge equipped the team members with various specially made magical artifacts. The "Ice-Breaking Spirit Boat" can travel quickly across the ice field and has the ability to resist extreme cold; the "Spirit Shadow Tracking Talisman" can track spiritual energy fluctuations and lock onto targets even in complex environments; the "Concealment Cloak" can hide the user's aura and avoid being discovered by enemies.

The Linghe Merchant Guild prepared a large amount of supplies, including warming pills, spirit crystals that could quickly restore spiritual power, and various tools for breaking formations and mechanisms. The guild also provided the team with a detailed map of the far north ice plains; although the map contained very little information about the Dark Abyss, it was better than nothing.

Under the guidance of their elders, the sword cultivators of the Spirit Sword Sect underwent targeted training to prepare for potential dangers. They enhanced their combat capabilities in extremely cold environments and honed their sword skills to better meet unknown challenges.

The team set off one early morning aboard the "Icebreaker Spirit Vessel," speeding towards the far north ice plains. As they approached the ice plains, the temperature plummeted, and fierce winds whipped up blizzards. The "Icebreaker Spirit Vessel" struggled through the snowstorm, the surrounding ice plains stretching as far as the eye could see, a white world filled with endless cold and desolation.

As they ventured deeper into the ice field, they found the environment increasingly eerie. Huge icebergs, like ferocious beasts, stood atop the ice field, with faint blue lights shimmering within them, as if concealing some mysterious power.

The experts from the Linghe Chamber of Commerce took out their detection magic treasures, attempting to sense the surrounding spiritual energy fluctuations. However, the information returned by the treasures was chaotic and disorganized, seemingly interfered with by some powerful force.

"Be careful, something's not right here," the expert from the Chamber of Commerce whispered a warning.

The team members immediately became alert. The sword cultivators of the Spirit Sword Sect drew their swords, while the disciples of the Myriad Treasures Pavilion gripped their magical weapons, ready to deal with any emergencies.

Just then, a group of ice beasts resembling polar bears suddenly appeared on the ice field. These ice beasts were enormous, exuding a chilling aura, and their eyes gleamed with a bloodthirsty light. They roared and charged towards the team.

"Prepare for battle!" shouted the elder of the Spirit Sword Sect, and the sword cultivators quickly formed a sword formation. The sword formation gleamed with cold light on the icy plain, sword energy crisscrossing as they engaged in fierce combat with the ice beasts.

The disciples of Wanbaoge manipulated their magical artifacts to attack the ice beasts. The flames spewed from the "Flame Dragon Cauldron" burned fiercely on the ice plain, attempting to melt the ice beasts' bodies; the lightning released by the "Nine Heavens Thunder Pearl" exploded among the ice beasts, causing some of them to tremble violently.

The experts of the Spirit Union Merchant Guild used spells to try to weaken the ice beast's power. They cast a "Slowing Charm" to slow the ice beast's movements and a "Freezing Charm" to try to freeze it in place.

With everyone's combined attack, the number of ice beasts gradually decreased. However, at that moment, an exceptionally large ice beast burst out of the iceberg. The ice layer on this ice beast was even thicker, and the chilling aura it emitted was even stronger. It opened its massive maw, and a powerful blast of cold air swept towards the team.

The team members felt an unprecedented crisis. Whether they could successfully resist the attack of this powerful ice beast and uncover the secrets of the Dark Abyss remained to be seen.
