The deep roar echoed continuously within the ice cave, seemingly coming from all directions, making it difficult to pinpoint its exact location. Su Ran frowned, signaling everyone to form a circle back-to-back and be on high alert. As the roar drew closer, the air in the ice cave seemed to be stirred by an invisible force, becoming increasingly cold and biting.

Suddenly, a massive black shadow burst forth from the depths of the cave, its speed so great that no one could react. The group only felt a strong gust of wind rush towards them, and then a ferocious beast resembling a giant wolf appeared before them. This giant wolf was covered in a thick layer of ice armor, shimmering with a ghostly blue light. Two sharp fangs protruded from its mouth, gleaming with a chilling glint. Its eyes, like two burning green flames, were filled with wildness and ferocity, staring menacingly at the group.

"This is an Ice-Armored Frost Wolf. It's said to possess powerful ice-type abilities and is extremely ferocious. Everyone be careful and don't attack rashly. Observe its movements first," the old man said solemnly. Su Ran nodded slightly. She gripped her ice sword tightly, her eyes fixed on the Ice-Armored Frost Wolf, and crouched slightly, ready to launch an attack at any moment.

The Ice-Armored Frost Wolf slowly paced around the group, its hostile gaze sweeping over each person as if searching for a weakness in their defenses. Suddenly, it lunged at a disciple with a powerful kick. The disciple reacted swiftly, immediately casting an ice shield to defend himself. The Ice-Armored Frost Wolf's claws slammed into the shield, producing a sharp crack, and cracks appeared in the shield.

Seeing this, Su Ran flashed forward like a white streak, rushing towards the Ice-Armored Wolf. Her ice sword gleamed with a sharp light as she thrust it towards the wolf's neck. Sensing the threat behind it, the Ice-Armored Wolf quickly abandoned its attack on the disciple and turned to use its ice armor to block Su Ran's attack. The ice sword struck the ice armor, sending up a spray of ice shards, but it failed to inflict any real damage on the Ice-Armored Wolf.

The other disciples also unleashed their spells, raining down ice arrows and ice spikes at the Ice-Armored Wolf. The Ice-Armored Wolf roared, spewing forth a blue icy flame that melted all the incoming spells. The icy flame, undiminished in its force, continued its onslaught towards the group. Su Ran quickly cast an ice-based defensive spell, forming a sturdy ice wall in front of them. The icy flame struck the ice wall, producing a hissing sound, and the ice wall began to slowly melt.

Just as everyone was locked in a stalemate with the Ice-Armored Wolf, Su Ran suddenly noticed that a patch of ice armor on the wolf's belly was slightly darker in color, seemingly a weak point in its defense. "Listen up, everyone! Focus your attacks on its belly; that might be its weak point!" Su Ran shouted.

Upon hearing this, everyone immediately adjusted their attack direction, directing all their spells towards the Ice Armor Wolf's belly. The Ice Armor Wolf seemed to sense the danger and tried to dodge, but the attacks from Su Ran and the others surged like a tidal wave, making it difficult for it to escape. As the spells struck the Ice Armor Wolf's belly, cracks finally appeared in the dull ice armor.

The Ice-Armored Wolf howled in agony, suddenly leaping high into the air and spinning, its ice armor falling away and transforming into countless sharp ice shards that shot towards the group. Su Ran and the others hurriedly cast defensive spells to block them, and for a moment, ice shards flew everywhere, creating chaos within the cave.

Taking advantage of the moment when ice shards were flying, Su Ran seized the opportunity and used her movement technique to quickly approach the Ice-Armored Wolf. The ice sword in her hand, imbued with all her spiritual power, transformed into a dazzling icy beam, and stabbed towards the Ice-Armored Wolf's abdomen. This sword strike, containing all of Su Ran's power, pierced directly through the Ice-Armored Wolf's abdominal armor and penetrated its body.

The Ice-Armored Wolf let out a piercing scream and crashed heavily to the ground. It struggled to get up, but Su Ran's ice sword was firmly embedded in its abdomen, rendering it immobile. Seeing this, the other disciples swarmed around it, preparing to deliver the final blow.

Just then, the Ice Armored Wolf suddenly spoke in human language: "Spare me, and I can tell you the secrets of this ruin and the ancient heritage hidden here." Everyone was stunned upon hearing this. Su Ran's heart stirred, and he asked, "Are you telling the truth? If you dare to deceive us, you will surely die."

A flicker of fear flashed in the Ice-Armored Frost Wolf's eyes, and it quickly said, "Everything I said is true. This ruin was once the cultivation ground of a powerful ice-elemental expert, and his legacy is hidden within. However, the place of the legacy is protected by numerous restrictions, and it can only be entered through specific methods. And I am one of the ferocious beasts guarding this legacy."

Su Ran and the old man exchanged a glance, pondering the Ice Armored Frost Wolf's words. The old man nodded slightly, and Su Ran said, "Alright."

Su Ran stared at the Ice-Armored Wolf, his expression serious. "Tell me in detail how to enter the Land of Inheritance. If you tell even a lie, you know the consequences." The Ice-Armored Wolf said weakly, "Deep in this ice cave, there is an ice platform with ancient runes engraved on it. The runes must be activated in a specific order to open the passage to the Land of Inheritance. But the order in which the runes are activated is hidden in the murals on the four walls of the ice cave."

Upon hearing this, everyone immediately dispersed to carefully examine the murals on the walls of the ice cave. The murals depicted various strange scenes: powerful ice-elemental beings unleashing earth-shattering spells, mysterious ice tribe sacrificial rituals, and grand scenes of ice beasts galloping. Su Ran stared intently at the murals, trying to find clues about the order in which the runes were activated.

Suddenly, a disciple pointed to a mural and exclaimed, "Senior Sister, look at this one! The arrangement of the ice beasts on it seems to hold a hidden secret." Everyone gathered around, and there, in the mural, a group of ice beasts were running around an ice platform. The number, position, and posture of the ice beasts seemed to follow a certain pattern. A flash of inspiration struck Su Ran. She connected it to the ice platform runes mentioned by the Ice Armor Wolf—could this be the clue?

After careful study and calculation, Su Ran finally determined the order in which the runes would be activated. She led everyone to the ice platform deep within the ice cave, took a deep breath, and, following the deduced sequence, circulated her spiritual energy to touch the runes on the ice platform. With her movements, the runes lit up one by one, emitting a soft glow.

The moment the last rune lit up, the ice platform slowly sank, revealing a deep passage. An ancient and mysterious aura permeated the passage, as if beckoning everyone. Su Ran, ice sword in hand, led the way into the passage, the others following closely behind.

The passage was dimly lit, with only occasional flashes of icy blue light from the walls providing some illumination. The group proceeded cautiously, wary of any potential danger. Suddenly, a massive ice door appeared ahead, its surface covered in intricate protective runes.

The Ice-Armored Frost Wolf had said that this ice gate was the final barrier to entering the Land of Inheritance, and that it could only be opened by breaking the restrictions on the gate. Su Ran stepped forward and carefully examined the runes, trying to find a way to break them. However, these runes were extremely profound, containing the unique power of the laws of ice-type experts, and for a moment, she was completely clueless.

The old man also stepped forward and joined Su Ran in their study. After a long period of discussion and experimentation, the two finally discovered a subtle energy cycle between the runes. Breaking this cycle would break the restriction.

Su Ran channeled her spiritual power, condensing an ice blade, and thrust it towards the key node of the rune. The rune, under attack, flickered and began to tremble violently. Just then, countless ice spikes suddenly surged from around the ice gate, shooting rapidly towards the group. The disciples quickly cast defensive spells, the ice spikes striking the shields with a series of rapid clanging sounds.

Taking advantage of a lull in the ice spikes' attack, Su Ran struck again, focusing all her efforts on the rune node. Finally, with a crisp cracking sound, the rune's energy cycle was broken, and the ice door slowly opened. Behind the door was a spacious ice chamber, in the center of which floated an ancient book emitting a soft blue light, surrounded by shimmering ice crystals.

Everyone entered the ice chamber, stunned by the sight before them. Su Ran knew that the ancient book was very likely the secret manual passed down by a powerful ice-elemental expert. However, just as she was about to take the book, a sinister laugh suddenly echoed from within the ice chamber. A figure formed from icy mist appeared before them, radiating a powerful aura, and coldly said, "You juniors, how dare you covet the legacy of your senior! Today is your death day!"
