I dominated the game from the start with cards.

The Shadow Fiend's low laughter echoed in the darkness, like a death knell, sending chills down everyone's spine. The surrounding darkness thickened, like an invisible giant hand slowly tightening, trying to crush them. Li Xuan took a deep breath, his mental energy scanning the surroundings like radar, trying to pinpoint the Shadow Fiend's exact location. "It's testing us," Li Xuan said in a deep voice. "Everyone be careful, stick to the plan." Lin Yu's eyes were resolute, his longsword gleaming coldly. He took a deep breath and charged into the depths of darkness like an arrow, letting out a loud battle cry. This battle cry acted as a fuse, instantly igniting the sparks of battle. The Shadow Fiend's attention was indeed drawn to Lin Yu. A gust of wind howled past, followed by an angry roar from the darkness. Lin Yu's speed was extremely fast, leaving afterimages in the darkness. He moved around the Shadow Fiend like a ghost, sometimes advancing, sometimes retreating, his agile movements making him unpredictable. The Shadow Demon's attacks, though fierce, repeatedly missed, its furious roars shaking the entire space. Mu Yang seized the opportunity, launching an attack from the side. His shield gleamed with golden light, like an unbreakable barrier, blocking the Shadow Demon's attacks, while his longsword pierced the Shadow Demon's weak points like a venomous snake. Although Mu Yang's attacks couldn't inflict substantial damage on the Shadow Demon, they successfully disrupted its judgment, creating more opportunities for Lin Yu. Old Zhou stood at the rear, his hands forming a hand seal, chanting incantations. With his incantation, the surrounding air began to fluctuate, a strange energy slowly spreading out, interfering with the Shadow Demon's perception. Sister Wu kept a close eye on her teammates, her hands emitting a soft green light, ready to heal any injured teammates. Li Xuan's mental energy was locked onto the Shadow Demon; he keenly sensed an anomaly in the Shadow Demon's energy fluctuations. He knew this was the perfect opportunity to strike. "Lin Yu, lure it to the stone pillar in the northeast!" Li Xuan's voice rang out in the mental link. Lin Yu understood immediately, his figure flashing as he sped towards the stone pillar in the northeast direction. The Shadow Demon, as expected, fell for the trap and angrily gave chase. Just as the Shadow Demon approached the pillar, Li Xuan moved. His dagger flashed with a ghostly blue light, like a bolt of lightning slicing through the darkness, aiming directly at the Shadow Demon's weak point. The Shadow Demon seemed to sense the danger and tried to dodge, but it was too late. Li Xuan's dagger struck the Shadow Demon's weak point precisely, and a surge of black energy erupted from the wound. The Shadow Demon let out a painful roar, its body trembling violently. "Now!" Li Xuan shouted. Mu Yang, Lin Yu, and Elder Zhou launched their attacks simultaneously, three beams of light intertwining and striking the Shadow Demon fiercely. The Shadow Demon's body began to crumble, turning into a cloud of black smoke that slowly dissipated into the air. Just when everyone thought the battle was over, the ground suddenly trembled violently, and an even more powerful dark aura surged from the depths of the earth. A colossal figure slowly emerged from the darkness… “What…what is this?!” Lin Yu cried out in terror. Li Xuan’s expression was grave as he stared intently at the enormous figure, saying slowly and deliberately, “It seems the real battle…has only just begun…” The Shadow Demon, realizing it had been tricked, let out a deafening roar. Its massive body trembled violently, and the surrounding dark aura churned like boiling water. A powerful dark shockwave emanated from it, spreading outwards in all directions. Wherever the shockwave passed, the ground cracked and rocks shattered, as if the end of the world had arrived. “Scatter!” Li Xuan had anticipated this and shouted a warning the instant the Shadow Demon roared. He flashed behind a huge rock. Mu Yang and Lin Yu also reacted quickly, each finding cover to take refuge. Old Zhou, with his rich experience, swiftly formed hand seals the instant the shockwave struck, enveloping him in a pale golden light that blocked its impact. Sister Wu reacted a fraction slower, caught in the aftershocks, letting out a muffled groan as her face instantly turned pale. "Sister Wu, are you alright?" Lin Yu asked with concern. Sister Wu, enduring the pain, shook her head: "I'm fine, just a minor injury, nothing serious." She gritted her teeth, her hands flashing with green light as she silently healed herself, while simultaneously monitoring her teammates' condition, ready to provide support at any moment. Li Xuan, hiding behind a rock, scanned his surroundings like a radar, searching for usable terrain. He noticed some large rocks and metal debris scattered around, and an idea immediately formed in his mind. "Mu Yang, Lin Yu, move those rocks and metal debris over here to build defensive fortifications!" Li Xuan issued the command via mental link. Mu Yang and Lin Yu immediately sprang into action. Risking being caught in the aftershocks, they moved the surrounding rocks and metal debris together, quickly constructing makeshift defensive fortifications under Li Xuan's command. The Shadow Demon's dark shockwaves came wave after wave, seemingly endless. Each impact caused the ground to tremble violently, and the fortifications teetered on the brink of collapse. Sister Wu's injuries worsened due to the strenuous activity, but she endured the pain, providing treatment and support to her teammates. Her face grew increasingly pale, and fine beads of sweat appeared on her forehead, but she never uttered a complaint, silently persevering. "This won't do; Sister Wu's injuries are getting more and more serious," Lin Yu said, his heart filled with worry as he watched Sister Wu's suffering. "We must find a solution as soon as possible," Mu Yang said, his brow furrowed. Li Xuan's mental perception constantly monitored the Shadow Demon's every move; he noticed that in its rage, the flow of its dark power had become slightly disordered. A barely perceptible sneer appeared on Li Xuan's lips... He said in a low voice, "Perhaps, our chance has come..." "Its power is disordered, just three inches to the left of its chest!" Li Xuan's voice was low and urgent, transmitted to Mu Yang and Lin Yu's minds through the mental link. "Concentrate your firepower on that spot, don't hesitate!" Mu Yang's eyes narrowed, and the light in his longsword surged, the sword energy like a rainbow, piercing straight for the Shadow Demon's chest.

Lin Yu wielded his giant axe, condensing violent energy into a sharp axe beam that followed closely behind Mu Yang's sword energy, slashing towards the Shadow Demon. The Shadow Demon's massive body trembled slightly, seemingly sensing danger. It attempted to gather dark power for defense, but the chaotic nature of its power prevented it from effectively controlling it. Mu Yang's sword energy and Lin Yu's axe beam struck precisely the areas where the Shadow Demon's power was disordered, like two bolts of lightning tearing through the darkness, leaving two deep, bone-revealing wounds on the Shadow Demon's chest. "Roar!" The Shadow Demon let out a painful roar, its body trembling violently, and the surrounding dark energy churned even more violently. Its wounded areas emitted unstable dark energy, like a bomb about to explode. "Its power is starting to get out of control!" Li Xuan keenly noticed the change in the Shadow Demon, a glint of light flashing in his eyes. "Continue the attack, don't give it a chance to breathe!" Mu Yang and Lin Yu dared not slacken in the slightest, fully unleashing the energy within their bodies, pouring a series of sharp attacks onto the Shadow Demon. The Shadow Demon's defenses weakened, its wounds multiplied, and its massive body swayed precariously, seemingly on the verge of collapse. Hidden behind the rocks, Elder Zhou had been silently observing the battle. His deep eyes gleamed with wisdom, as if he understood everything. Seeing that the Shadow Demon's power was completely out of control, he took a deep breath and slowly raised his staff. The gem at the top of the staff emitted a dazzling light, and a powerful energy wave emanated from Elder Zhou. He chanted incantations, ancient and mysterious spells echoing in the air. "The time has come!" Elder Zhou shouted, and the gem at the top of the staff shone brightly, a golden beam of light shooting out from the staff, roaring like a golden dragon as it charged towards the Shadow Demon. The golden beam of light, Mu Yang's sword energy, and Lin Yu's axe light struck the Shadow Demon almost simultaneously. The Shadow Demon let out a shrill scream, its body began to twist violently, and its dark aura dissipated rapidly like a deflated balloon. With a deafening boom, the Shadow Demon's massive body collapsed, transforming into a cloud of black smoke that vanished without a trace. The surrounding darkness dissipated, revealing the desolate landscape. Li Xuan, Mu Yang, and Lin Yu all breathed a sigh of relief. Exhausted, they wore expressions of triumphant joy. Sister Wu also breathed a sigh of relief, enduring her pain to heal her teammates. Suddenly, the ground trembled, and a door emitting a ghostly blue light appeared where the Shadow Demon had stood. Behind the door seemed to connect to another world, radiating an unknown and mysterious aura. Li Xuan stared at the door, a complex expression flashing in his eyes. He knew that what awaited them behind this door was an even more dangerous and unknown challenge. “Let’s go,” Li Xuan turned to Mu Yang and Lin Yu, his tone calm. “We should set off.” He walked towards the door first, his figure gradually disappearing into the eerie blue light… Mu Yang and Lin Yu exchanged a glance, their eyes filled with determination. They followed Li Xuan’s footsteps, stepping into the unknown door… Old Zhou watched their disappearing figures, a hint of worry flashing in his eyes. He murmured to himself, “I hope everything goes well for them…” Sister Wu walked to Old Zhou’s side, gently patting his shoulder. She said nothing, simply standing silently beside him, watching together the door radiating the eerie blue light… A golden pillar of light, like the light of divine punishment, carrying a world-destroying power, erupted from Old Zhou’s staff. At the same time, Mu Yang’s sword energy poured down like a galaxy, and Lin Yu’s giant axe, imbued with the power to split mountains and cleave the earth, the three powerful energies, under Li Xuan’s precise guidance, almost simultaneously struck the chaotic energy core in the Shadow Demon’s chest. "Aaaaah—" The Shadow Demon let out a shrill scream, no longer the menacing growl, but a wail filled with pain and despair. Its massive body trembled violently, as if enduring unspeakable agony. Black mist surged wildly from its body, only to be swiftly swallowed up by the golden pillar of light. The Shadow Demon's body began to disintegrate, black fragments scattering like shattered glass, eventually turning into black dust and dissipating into the air without a trace. Silence. A deathly silence enveloped this desolate land. Li Xuan, Mu Yang, and Lin Yu were all panting heavily from exhaustion, but their faces beamed with the joy of victory. Sister Wu, dragging her injured body, walked to their side and gently healed them, a relieved smile on her face. Suddenly, the earth trembled, and where the Shadow Demon had stood, a door emitting a ghostly blue light slowly appeared. This door appeared out of thin air, like an entrance to another world, exuding a mysterious and unknown aura. Elder Zhou, leaning on his staff, walked to the door, carefully examining it with a furrowed brow. He gently touched the eerie blue light emanating from it, and a chilling energy instantly coursed through his body, causing him to shiver. "This door..." Elder Zhou withdrew his hand, his expression grave, "...seems to lead to an even more dangerous place." Li Xuan walked to Elder Zhou's side, looking at the door radiating the eerie blue light, a complex expression flashing in his eyes. He understood that what awaited them behind this door was an even greater challenge, but he felt no fear. For revenge, for uncovering the truth behind his sect's destruction, he had to continue forward, no matter what lay ahead. "Let's go," Li Xuan turned to Mu Yang and Lin Yu, his tone resolute, "We should set off." He took a deep breath and led the way towards the door, his figure gradually disappearing into the eerie blue light. Mu Yang and Lin Yu exchanged a glance, their eyes filled with determination. They followed Li Xuan's footsteps and stepped into the unknown door… Sister Wu watched their disappearing figures, her eyes filled with worry. She gently walked to Old Zhou's side and whispered, "Will they be alright?" Old Zhou gazed at the door emitting a ghostly blue light, slowly shook his head, and sighed, "I don't know… but I believe in them." The ghostly blue light gradually dissipated, and the door vanished, leaving only a desolate, empty land and an unsettling silence… Suddenly, Old Zhou abruptly turned his head, looking into the distance, a flicker of fear in his eyes, "What was that…?"
