The survivors rested briefly in the ice chamber, calming their wildly beating hearts and exhausting their spiritual energy. The tense atmosphere in the ice chamber gradually faded as the shadowy figure disappeared, replaced by a growing curiosity about this mysterious ice chamber. Su Ran stood up, her gaze sweeping around the ice chamber. She knew that this trip to the ice chamber was far more than just repelling the shadowy figure; it must hold untold secrets and opportunities.

Everyone rose and followed Su Ran, exploring this mysterious space together. The walls of the ice chamber were covered with various strange runes and patterns, which emitted a faint icy blue light, as if telling ancient stories. The second senior sister leaned closer to examine them carefully, muttering to herself, "I have never seen these runes before, and they do not seem to be any of the rune systems recorded in our sect's records."

Su Ran gently stroked the runes on the wall, trying to glean some information from them. Suddenly, her fingers touched a slightly recessed area. As she channeled her spiritual energy into it, the runes on the wall shone brightly, and the once smooth wall slowly opened, revealing a deep passage. A faint icy mist filled the passage, and an ancient and mysterious aura wafted towards her.

The group exchanged glances, their eyes gleaming with excitement and anticipation. Su Ran took the lead, stepping into the passage, with the other disciples following closely behind. The passage was narrow, only wide enough for two people to walk side by side. The walls on both sides were inlaid with ice crystals that emitted a soft blue light, illuminating the path for everyone.

As they walked, a huge circular stone chamber appeared ahead. In the center of the chamber stood a lifelike ice sculpture depicting an elderly man in an ice-blue robe. The man had a kind face and deep, penetrating eyes, as if surveying the world below. At the foot of the ice sculpture lay an ancient book that emitted a faint glow.

Su Ran and the others cautiously approached the ice sculpture. Su Ran crouched down and gently picked up the ancient book. The book was cool to the touch, and three ancient characters were engraved on the cover—"The Holy Scripture of the Ice Spirit." The moment Su Ran touched the book, a flood of information rushed into her mind.

Su Ran closed her eyes tightly, focusing all her energy on digesting this massive amount of information. After a long while, she slowly opened her eyes, her gaze filled with surprise and joy. She said to everyone, "This 'Ice Spirit Holy Scripture' is the supreme inheritance of the Ice Spirit Clan from a thousand years ago, recording the Ice Spirit Clan's unique cultivation methods and various lost ice-based spells."

The disciples were both surprised and delighted upon hearing this. The Ice Spirit Clan were the legendary supreme rulers of ice-type spiritual power, and the preciousness of their inherited techniques was self-evident. The eldest disciple excitedly said, "If we can learn such a precious inheritance, our ice-type cultivation will surely reach a new level."

However, Su Ran frowned slightly and said, "Although the Ice Spirit Holy Scripture is extremely precious, obtaining its inheritance is not easy. According to the information, we need to pass three tests set by the Ice Spirit Clan in order to truly obtain the inheritance."

Upon hearing this, everyone's expressions tightened, but the determination in their eyes remained unwavering. Among the younger disciples, one named Lin Feng clenched his fist and said, "Senior Sister, no matter how difficult the trial is, we are willing to give it a try." The other disciples nodded in agreement.

Looking at the determined eyes of everyone, Su Ran felt a surge of warmth in her heart. She said, "Alright, since everyone is so determined, let's face the test. The first test is the Ice Spirit Illusion. Once inside, we will confront the fears and illusions deep within our hearts. Only by overcoming these can we pass."

Su Ran placed the ancient book back at the foot of the ice sculpture. The book flashed, and a huge ice-blue magic circle appeared on the floor of the stone chamber. The magic circle shimmered, and a powerful suction force pulled everyone into it.

When everyone opened their eyes again, they found themselves in a frozen wasteland. A fierce wind howled, and snowflakes cut their faces like sharp blades. Su Ran looked around, her heart filled with vigilance; she knew this was the beginning of the Ice Spirit Illusion.

Suddenly, a group of dark figures appeared in the distance, rushing towards the group. As they drew closer, they realized that these figures were powerful enemies they had encountered during their cultivation. Lin Feng saw the demonic cultivator who had nearly killed him during his training; the cultivator wielded a demonic blade, his eyes gleaming with bloodlust, and lunged at Lin Feng.

Although Lin Feng felt fear, he thought of his senior sister and the others, gritted his teeth, gripped his ice sword tightly, and unleashed "Ice Blade Storm," sending countless ice blades hurtling towards the demonic cultivator. The demonic cultivator, however, neither dodged nor evaded, charging directly into the ice blades. The ice blades struck him as if they were hitting steel, sending sparks flying everywhere.

At the same time, the eldest disciple also faces a test. He witnesses a catastrophe that befell the sect in his youth, with countless fellow disciples before his eyes.

Faced with the illusion of a sect catastrophe, the senior disciple saw familiar fellow disciples falling amidst a rain of blood, and a wave of pain and self-reproach washed over him. But he knew it was just an illusion, so he forced himself to steady his mind and unleashed the "Ice Dragon Roars to the Sky" technique. A gigantic ice dragon roared from his palm, charging towards the illusory enemies. Wherever the ice dragon passed, snow and ice swirled, attempting to dispel this cruel "catastrophe."

The second senior sister then recalled the confusion and self-doubt she felt during her cultivation bottleneck. A phantom figure, identical to her, appeared before her, constantly mocking and trying to shake her resolve. The second senior sister took a deep breath, circulated her spiritual energy, and an icy blue light shone around her. She shouted, "My heart is firm; how can you disturb it!" She then cast the "Ice Heart Purification Technique," and the light transformed into wisps that enveloped the illusion, gradually dissolving it.

On Su Ran's side, she faced the scene she feared most—her disciples suffering a brutal fate before her very eyes due to her flawed decision. Seeing their agonizing expressions, Su Ran felt as if her heart was being torn apart. But she instantly snapped back to reality; this wasn't real. Su Ran gathered all her spiritual power and cried out, "Ice Spirit Light, illuminate the illusion!" A dazzling ice-blue light erupted from her body, like a blazing sun, dispelling all the surrounding illusions.

Inspired by Su Ran's radiance, the other disciples also unleashed even greater power. Lin Feng was no longer afraid of the demonic cultivator. He pushed his ice-type spiritual power to its limit and unleashed his newly comprehended "Ice Shattering Stars." Countless ice shards shot towards the demonic cultivator like stars. This time, the demonic cultivator finally could not withstand it and vanished in a puff of black smoke.

As everyone overcame their fear and dispelled the illusions, the surrounding icy landscape began to collapse, and they returned to the circular stone chamber. Although their faces were somewhat tired, their eyes were filled with the relief of surviving a calamity and the joy of conquering themselves.

Looking at everyone, Su Ran said with satisfaction, "Everyone did very well and successfully passed the first test. Next is the second test—Ice Spirit Tempering." She looked at the ice sculpture, and saw that the ice sculpture's hands slowly rose, and two balls of ice spirit fire radiating extreme cold appeared in its palms.

The ice sculpture spoke softly, its voice seemingly echoing from ancient times: "Step into this Ice Spirit Fire, and let your bodies endure the tempering of the Ice Spirit's power. If you can endure for a quarter of an hour, you will pass." This Ice Spirit Fire may not seem large, but the icy power it contained made everyone feel as if their souls were about to be frozen just by looking at it from afar.

Without the slightest hesitation, the eldest disciple stepped into the Ice Spirit Fire first. In an instant, extreme cold assaulted his entire body, as if countless ice needles were piercing his skin and bone marrow simultaneously. The eldest disciple gritted his teeth, frantically circulating his spiritual energy within his body to resist the chill. A thick layer of ice armor quickly formed on his body, but with his indomitable will, he did not step out of the ring of fire.

Seeing her eldest brother's unwavering resolve, the second senior sister stepped into another ball of icy fire. The chilling power instantly enveloped her, and she felt her consciousness gradually blurring, but she kept reminding herself not to give up. The second senior sister used the "Ice Heart Technique" to keep her mind clear, resisting the excruciating pain brought on by the icy tempering.

Seeing their senior brother and sister struggling against the flames, the younger disciples mustered their courage and stepped into the Ice Spirit Fire. Lin Feng groaned as soon as he entered the fire; the cold, like a leech, gnawed at every inch of his body. But seeing his senior brothers and sisters persevering, he gritted his teeth, endured the pain, and struggled to circulate his spiritual energy.

Su Ran stood aside to protect everyone while keeping a close eye on the time. Time slowly passed in this tense atmosphere, each second feeling like a year to everyone in the Ice Spirit Fire.

As the fifteen-minute mark approached, several young disciples could no longer endure the ordeal and staggered, attempting to step out of the ring of fire. Seeing this, Su Ran shouted, "Everyone, hang in there! We're almost there! Remember all our previous efforts; we can't let this go to waste!" Hearing Su Ran's call, the disciples who were about to give up were rekindled with fighting spirit, stubbornly stopping their steps and gritting their teeth to persevere.

Finally, after a quarter of an hour, the icy flames in the ice sculpture's palm slowly died down. Exhausted, everyone collapsed to the ground, but each body radiated an even purer and more powerful surge of ice-based spiritual energy.
