Li Wei summoned every ounce of his inner power and open all his meridians to enhance his power. Even though Li Wei know it was dangerous move and it will surely become death of him yet he still need to do it to defeat the Shadow Serpent Sect master. Drawing upon the newfound power of his elemental sword with a desperate resolve. With a defiant roar, Li Wei unleashed a final flurry of strikes, each blow infused with celestial energy as he sought to turn the tide of battle in his favor. His sword danced through the air with unparalleled speed and precision, carving through the darkness with a relentless determination. He sought to break through the Shadow Serpent Sect master defenses. The chamber erupted in a blinding flash of light as the dark energies clashed with celestial might, illuminating the chamber in a dazzling display of power.

The Shadow Serpent Sect master, taken aback by Li Wei sudden resurgence and the sudden surge of power from the elemental sword, found himself on the defensive. Li Wei movements fluid and decisive as he seized the opportunity to press his advantage.

With each strike, Li Wei sword cut deeper, not just through the physical form of the Shadow Serpent Sect master but through the dark energy that sustained him. The Shadow Serpent Sect Master, his confidence waning, unleashed a barrage of dark energy, but Li Wei, guided by the light of his sword, sliced through it, reaching the core of the dark power until the Shadow Serpent Sect master primodial spirit broken into pieces.

In a final, monumental effort, Li Wei sword pierced the heart of the darkness, the impact sending a shockwave of light that illuminated the sect and the skies above.

"No! This cannot be!" the Shadow Serpent Sect Master screamed, his form beginning to disintegrate, the dark energy that had swelled within him now consuming him. "I was to be eternal!"

Li Wei, standing tall despite his injuries, watched as the Shadow Serpent Sect Master turned to dust, his voice carrying a mix of sorrow and resolve. 

"True strength lies in knowing when to end the cycle of greed."

As the Shadow Serpent Sect Master form dissipated completely, the darkness that had choked the world began to recede, light returning to the skies.

While for Xiao Shang, despite the pain that racked her body and the exhaustion that threatened to overwhelm her, Xiao Shang refused to falter. With each passing moment, her determination only grew stronger, fueled by the love and devotion she felt for Li Wei. She keep on hitting the barrier.

As the Shadow Serpent Sect Master gone, the barrier become weak. And then, just when she felt her strength beginning to wane, a crack appeared in the barrier before her, a glimmer of hope amidst the darkness. With renewed determination, Xiao Shang redoubled her efforts, pouring every ounce of her remaining energy into breaking through the seal.

As Xiao Shang finally breached the sealed entrance, her heart raced with a mix of fear and determination. She had endured the agonizing wait outside, her every heartbeat echoing with the desperation to reach Li Wei. Now, as she laid eyes on him, battered and broken yet still standing, relief flooded her being. 

Li Wei collapsed to his knees, the sword slipping from his grasp, as exhaustion and relief washed over him. The battle was over, the balance restored, but at great personal cost.

"Li Wei!" she cried out, her voice a mix of worried and anguish as she rushed towards him, heedless of the dangers that still lurked within the crumbling sect. 

Li Wei, his strength waning, managed a weak smile as he saw Xiao Shang figure approaching through the haze of pain. Her presence was a balm to his battered soul, a beacon of light in the darkness that threatened to consume him.

"Xiao Shang..." he whispered hoarsely, his voice barely above a whisper as she fell to her knees beside him, enveloping him in a tight embrace. Tears streamed down her face, mingling with the blood and grime that stained Li Wei torn garments.

"Shh, don't cry.." Li Wei murmured softly, his voice strained with effort as he gently caressed her cheek. "I'm still here, I'm still with you."

Xiao Shang shook her head, her sobs wracking her body as she clung to him desperately. "I thought I'd lost you.." she whispered, her words choked with emotion. "I couldn't bear the thought of a world without you in it."

Li Wei heart clenched at her words, a surge of love and pain coursing through him. Despite his own agony, he mustered a reassuring smile, brushing a lock of hair from her tear-streaked face. 

"You haven't lost me, Xiao Shang. I'm right here, and I'm not going anywhere."

But even as he spoke, Li Wei knew the truth of his condition. His spiritual power was shattered, his body broken and battered from the fierce battle with the Shadow Serpent Sect Master. He could feel the darkness creeping in at the edges of his consciousness, threatening to pull him into its abyss.

Xiao Shang, sensing his struggle, tightened her embrace, her tears soaking into his tattered hanfu. "We'll get through this together." she whispered fiercely, her voice trembling with resolve. "I won't leave your side, not for a moment."

Li Wei heart swelled with gratitude and love for this woman who had stood by him through every trial and tribulation. With the last vestiges of his strength, he returned her embrace, holding her close as if to anchor himself to the world of the living.

As Li Wei consciousness slipped away, his grip on reality growing tenuous, Xiao Shang heart clenched in despair. She held him tightly, willing him to stay with her, but she could feel his life force fading with each passing moment.

"Please, don't leave me..." she pleaded, her voice trembling with fear and anguish. Her vision blurred by tears cascading down her cheeks. "Stay with me, Li Wei!"

But even as she spoke, a flicker of light pierced through the darkness, drawing her attention. In its glow, she saw the silhouette of a figure approaching, and as the light grew brighter, the features of a man became discernible.

"Who... who are you?" Xiao Shang asked, her voice barely above a whisper as she stared at the newcomer.
