After returning from Lingxiao Immortal Island, Li Xiao and Lin Yao had cultivated in seclusion at Tianji Pavilion for some time. They gained an increasingly thorough comprehension of the Lingxiao Divine Scripture, and their strength stabilized at the Nascent Soul Mid-stage. Every movement they made carried powerful spiritual fluctuations, making them top-tier existences among the younger generation of disciples in the pavilion.
However, the peaceful days did not last long. One day, the Master of Tianji Pavilion urgently summoned everyone and said with a solemn expression, "Recently, our scouts reported that a mysterious dark force has appeared in the distant far north. The aura it emits is evil and powerful, leaving devastation in its wake. Many weak sects and immortal cultivation families have been wiped out. Moreover, according to reliable sources, this dark force seems to be related to the lingering soul of a demon god sealed since ancient times. If we do not stop it in time, I fear the entire world of immortal cultivation will plunge into eternal doom."
Upon hearing this, everyone wore expressions of panic and began to whisper among themselves. Li Xiao and Lin Yao exchanged a glance, a flash of resolve crossing their eyes. Li Xiao stepped forward, cupped his fists, and said, "Pavilion Master, at such a critical juncture, Yao'er and I are willing to go to the far north to investigate the truth behind this dark force. If possible, we will do our utmost to eradicate it and protect the peace of the immortal cultivation world." Lin Yao also nodded slightly, standing beside Li Xiao with a firm gaze.
Looking at them, the Pavilion Master's eyes were filled with gratification and praise as he nodded and said, "Good. Both of you possess extraordinary strength, as well as resourcefulness and courage. This trip may be fraught with danger, but only you are truly suited for it. I will send a few elders to accompany you so you can look out for one another along the way. Remember, if the situation turns unfavorable, do not force things; make sure to preserve your lives above all and return to report."
After receiving their orders and making brief preparations, Li Xiao and Lin Yao set out on the journey to the far north alongside several elders. Along the way, they pressed on without rest, traveling day and night. The further north they went, the colder the weather became, and the surrounding spiritual Qi grew increasingly thin and chaotic, as if polluted by an evil force.
As they approached the core region of the far north, thick black mist filled the sky, blotting out the sun and making it feel as though they were plunged into perpetual night. The ground was covered in a thick layer of ice, beneath which bizarre sounds echoed from time to time, as if something terrifying was struggling and writhing.
Suddenly, the ice ahead shattered, and a giant frost beast leaped out from an icy crevasse. Its body was as massive as a mountain, covered in hard ice armor, and the freezing breath exhaled from its mouth could instantly freeze the surrounding air. The beast let out a heaven-shaking roar and lunged toward the group.
Li Xiao's gaze sharpened as his Lingxiao Sword instantly unsheathed, the blade humming and emitting a dazzling radiance. Employing the Spirit-Control Sword Technique from the Lingxiao Divine Scripture, his figure flashed like lightning as he charged at the frost beast. Waving his long sword, he slashed wave after wave of sharp sword Qi toward the beast's vital spots. Meanwhile, Lin Yao stood at the rear, forming hand seals to cast the water-attribute spell "Ice Spirit Roar." The surrounding moisture rapidly condensed into countless sharp ice cones, shooting toward the frost beast like a torrential rainstorm. Working in coordination with Li Xiao's attacks, they managed to restrict the beast's movements for a time.
The elders also made their moves, each displaying their signature skills. For a time, spiritual light flashed, and powerful attacks rained down upon the frost beast. However, the beast had thick hide and astonishing defense; while everyone's attacks inflicted some injuries, they failed to deal a fatal blow and only further enraged it.
The frost beast frantically swung its huge claws, sweeping toward the group. Each sweep generated a powerful wind pressure that was difficult to withstand. Seeing this, Li Xiao's expression grew stern. He took a deep breath, furiously circulating the spiritual Qi within his body to push the power of the Lingxiao Divine Scripture to its limit, unleashing a move called "Lingxiao Heaven-Shattering Slash." A massive seven-colored sword Qi shot from his sword, slicing toward the frost beast's head like a rainbow piercing the sun.
At the same time, Lin Yao cast her ultimate spell, "Water Spirit Chaotic World-Destroying Curse." A water-blue light imbued with the Chaotic Force surged toward the beast, merging with Li Xiao's sword Qi to unleash a heaven-destroying power. Under the impact of this mighty force, the frost beast finally could no longer hold out; it collapsed with a crash, turning into a pile of ice fragments.
The group gasped slightly for breath, feeling a secret sense of relief in their hearts. Yet they also understood that this was only the beginning, and the dangers waiting ahead would likely be even more unimaginable. They continued forward, cautiously crossing an ice plain and arriving before a valley shrouded in dark mist.
A dense, evil aura permeated the valley, making one's hair stand on end. Li Xiao, Lin Yao, and the others walked into the valley with heightened vigilance. In the center of the valley stood an ancient, gloomy black altar carved with various strange runes. These runes flickered with an eerie dark-red light, as if whispering an ancient and evil curse.
Around the altar gathered a group of mysterious figures clad in black robes, their faces hidden in darkness so that their appearances could not be seen. Yet from the aura emanating from them, it was clear these people were no benevolent beings. The arrival of Li Xiao, Lin Yao, and the others naturally drew the attention of these mysterious figures, who slowly turned around and gazed coldly at the group.
One of the mysterious people let out a hoarse laugh and said, "I didn't expect anyone to still dare come to the far north to court death. Since you're here, don't even think about leaving alive." With a wave of his hand, a beam of black light shot toward the group.
Li Xiao swiftly sidestepped to dodge while swinging his Lingxiao Sword, shattering the black light with a bolt of sword Qi. He shouted sternly, "Who on earth are you people? Why release this dark force in the far north? Do you not know what kind of disaster this will bring to the immortal cultivation world?"
The mysterious person sneered and said, "A disaster? This immortal cultivation world is already rotten to the core; it's time for a reshuffle. And we shall be the masters of this new world. As for you lot, you are merely sacrifices to this revolution."
Upon hearing this, Li Xiao and Lin Yao burned with anger. Without wasting any more words, they charged directly at the mysterious figures. A fierce battle erupted instantly between the two sides. Li Xiao employed the Lingxiao Sword Technique, engaging the mysterious figures in close combat. His sword techniques were sharp and versatile, with every strike imbued with formidable spiritual power that prevented the mysterious figures from taking him lightly. Lin Yao cast spells from the side to provide support and cover for Li Xiao. Her water-attribute spells exerted even greater might in this freezing far north, sending ridges of ice and water arrows shooting toward the mysterious figures, leaving them with no defense against the blind spots.
The elders also joined the battle, engaging in fierce combat with the remaining mysterious figures. For a time, spiritual light flashed in the valley, battle cries shook the air, and the conflict reached a white-hot stage. However, the strength of these mysterious figures was formidable, and they seemed to have cultivated an evil combination formation. Coordinating with one another, they gradually gained the upper hand.
Li Xiao, Lin Yao, and the others felt their pressure steadily mounting, and their spiritual Qi consumption grew increasingly rapid. Yet they did not give up, stubbornly resisting all the same. Amidst the fighting, Li Xiao discovered that the mysterious figures' formation seemed to possess a flaw; if he could find an opportunity to break that flaw, he might just turn the tide of battle.
While fighting, he carefully observed the shifting patterns of the mysterious figures' formation, searching for that weak spot. Finally, an opportunity presented itself. When the mysterious figures launched a joint offensive, a brief moment of chaos appeared in their formation. Li Xiao's eyes lit up. Without hesitation, he unleashed the ultimate technique from the Lingxiao Divine Scripture, "Wrath of the Lingxiao Emperor," gathering all his spiritual Qi into his sword and transforming it into a massive seven-colored sword Qi that slashed directly toward the flaw in the mysterious figures' formation.
Lin Yao also perceived Li Xiao's intent and hurriedly cast a spell to assist his attack. Through their tacit coordination, Li Xiao's sword Qi successfully struck the flaw in the formation. Instantly, a powerful spiritual wave erupted; the formation was shattered, and the mysterious figures suffered a backlash, coughing up blood and staggering backward.
Seeing this, the morale of Li Xiao, Lin Yao, and the others soared. Seizing the opportunity, they launched an even more ferocious offensive. With everyone working together with one heart, the mysterious figures could no longer hold their ground and began to scatter and flee. Li Xiao, Lin Yao, and the others did not let them go; they pursued and cut down the mysterious figures one by one, leaving behind only a heavily injured individual to interrogate for more information regarding the dark force.
Li Xiao pressed his sword against the mysterious person's neck and asked coldly, "Speak, what kind of people are you? What is the origin and purpose of this dark force?"
The mysterious person turned pale, a trace of fear flashing in his eyes, but he stubbornly retorted, "Don't get cocky. We are merely servants of the Dark Demon God; his power is about to awaken. When that time comes, the entire immortal cultivation world will tremble beneath his feet. Ants like you cannot hope to stop him."
Hearing this, Li Xiao and Lin Yao's hearts sank. They realized the situation was far more grave than they had imagined. They continued their interrogation, but the mysterious person refused to reveal any further information and ultimately bit his tongue to commit suicide.
Left with no choice, Li Xiao, Lin Yao, and the others continued searching the valley for clues. They conducted a thorough search around the black altar and finally discovered a hidden cave entrance at its base. A denser dark aura drifted from the cave, sending chills down their spines.
Li Xiao, Lin Yao, and the others cautiously walked into the cave. It was dark and damp, with various unknown insects and moss crawling along the walls. After walking a distance down the cave, they arrived at a spacious cavern hall. In the center of the hall sat a massive black crystal coffin, carved with complex runes and patterns that flickered with a dark-red light, as if sealing something terrifying.
Approaching the crystal coffin, Li Xiao, Lin Yao, and the others felt a powerful and evil force emanating from it. This force made their hearts race uncontrollably and caused a heavy sensation in their bodies. They knew that what was sealed within the crystal coffin was likely the lingering soul of the Dark Demon God mentioned by the mysterious person.
Just as they prepared to study how to reinforce the seal, the crystal coffin suddenly trembled violently, and the light of the runes flickered with increasing frequency. Li Xiao's expression changed, and he shouted loudly, "Not good! This demon god's lingering soul is about to break the seal. Everyone, be careful!"
The group quickly turned vigilant, each unleashing their strongest defensive techniques to prepare for the impending crisis. With a loud crash, the lid of the crystal coffin was blown off by a powerful force, and a black figure slowly rose from within. A terrifying evil aura instantly filled the entire cavern hall.
Li Xiao looked closely and saw that the lingering soul of the Dark Demon God appeared human in shape, but its face was blurred, and its entire body was shrouded in a layer of black mist, obscuring its exact features. Its eyes flashed with a blood-red light, revealing endless greed and a desire for slaughter.
The Dark Demon God's lingering soul let out a piercing laugh and said, "Haha, foolish humans! Did you think you could stop me? Today is your day of death, and the end of this immortal cultivation world!" With a wave of its hands, a powerful dark force swept toward the group.
Li Xiao, Lin Yao, and the others hastily defended themselves, but they discovered that the power of the Dark Demon God's lingering soul was simply too immense. Their attacks struck him like stones sinking into the sea, having no effect whatsoever. Instead, they were driven back repeatedly by the impact of the dark force, and the spiritual Qi within their bodies suffered no small shock.
Li Xiao felt anxious at heart, knowing that if this continued, all of their lives would be lost. Desperately racking his brain for a countermeasure, a flash of inspiration suddenly struck his mind, reminding him of a method of applying purification power recorded in the Lingxiao Divine Scripture.
He quickly shared his idea with Lin Yao and the elders. Although they felt it was somewhat risky, having no better alternatives at the moment, they nodded in agreement. Taking a deep breath, Li Xiao began to circulate the Lingxiao Divine Scripture, mobilizing the spiritual Qi within his body in an attempt to condense the power of purification.
Lin Yao and the elders also assisted him with all their might from the side, providing spiritual support and cover. With everyone working in unison, Li Xiao finally succeeded in condensing a beam of purification light. Gripping the light of purification, he charged toward the lingering soul of the Dark Demon God, shouting at the top of his lungs, "Demon God, today shall be the day of your destruction!"
Seemingly perceiving the threat posed by the purification light, the Dark Demon God's lingering soul changed expression slightly and hurriedly mobilized his dark power to defend. Yet the might of Li Xiao's purification light was immense. Aided by Lin Yao and the elders, it steadily broke through the defense of the Dark Demon God's lingering soul, shooting straight toward its main body.
The lingering soul of the Dark Demon God let out a miserable scream as its body began to gradually dissipate upon being struck by the purification light. Unwilling to accept defeat, it struggled frantically, launching even more ferocious attacks in a desperate final resistance.
Li Xiao, Lin Yao, and the others clenched their teeth, defending with all their might against the attacks of the Dark Demon God's lingering soul while continuously strengthening the power of the purification light. After a fierce battle, under the formidable power of the purification light, the lingering soul of the Dark Demon God was thoroughly purified, vanishing without a trace.
Following the destruction of the Dark Demon God's lingering soul, the dark aura of the far north gradually dissipated. The black mist in the sky slowly cleared, and sunlight once again spilled over the land. Exhausted, Li Xiao, Lin Yao, and the others collapsed to the ground, relief and smiles on their faces.
They knew this crisis had finally been successfully resolved, yet they were also well aware that the future of the immortal cultivation world remained fraught with challenges and unknowns. They decided to return to Tianji Pavilion to report their experiences to everyone while simultaneously striving to further elevate their own strength to cope with any future crises.
In the days that followed, upon returning to Tianji Pavilion, Li Xiao and Lin Yao entered closed-door cultivation. They continuously studied the Lingxiao Divine Scripture, integrating their combat experience from the far north into their training, and their strength steadily grew. Meanwhile, their names resounded even more loudly throughout the immortal cultivation world, making them heroes and role models in the hearts of countless cultivators, inspiring them to work hard for the peace and tranquility of the immortal cultivation realm.
