The group followed Chen Jiuzhang closely, their eyes darting around the shifting corridors of the spatial maze. The sickly purple - black glow from the walls cast eerie shadows that seemed to dance and contort with a life of their own. Shen Qingluan held the fragment of the Imperial Jade Seal in front of her, its light barely cutting through the thick, oppressive darkness.Every few steps, the ground would suddenly tilt or rise, forcing them to scramble for balance. Su Nian's chains clinked nervously as she reached out to steady herself against the wall, only to recoil in horror. The surface was warm and slightly moist, as if the very stone was breathing. "This place... it's not right," she murmured, her voice echoing hollowly through the maze.Wu Laogou puffed on his pipe, the smoke providing a brief moment of normalcy in the otherwise surreal environment. "Aye, and I don't like the feel of it. We're walking into a trap, I can feel it in me bones."Just then, a soft, whispering laughter filled the air. It seemed to come from everywhere and nowhere at once, sending chills down their spines. Zhang Chengying tightened his grip on his broken peachwood sword, his eyes wide with alarm. "Who's there? Show yourself!"Luna's starlight - woven gown flickered, and she raised her hands defensively. "It's a trick. Don't let the sound distract you." But even as she spoke, the laughter grew louder, accompanied by faint whispers that seemed to be speaking directly into their minds.Chen Jiuzhang closed his eyes, focusing on the pull from the crystal - key. The humming within the artifact had grown more insistent, as if it was struggling against some unseen force. "Ignore the voices. The key will guide us."But as they pressed on, the maze began to play more sinister tricks. Images flashed before their eyes—visions of loved ones in distress, of their greatest fears come to life. Shen Qingluan froze, her face pale, as she saw her homeland in ruins once again. Zhang Chengying stumbled back, his sword clattering to the ground, as he was confronted with an army of his own failures.Su Nian was the first to break free from the illusions. Her chains lashed out, cutting through the air as if striking at an invisible enemy. "It's all fake! Don't fall for it!" Her shout seemed to break the spell, and the others shook off the visions, their expressions determined.Suddenly, the ground beneath them gave way, and they found themselves in a large, circular chamber. In the center stood a pedestal, on which rested a strange, pulsating orb. The orb was a swirling mass of black and purple energy, and it seemed to be the source of the maze's power.But before they could approach it, the chamber was filled with a blinding flash of light. When the light faded, a figure stood before them. It was a woman, her form translucent and shifting like smoke. Her eyes glowed a deep, blood - red, and she wore a crown of sharp, jagged crystals."Foolish mortals," she hissed, her voice like a thousand snakes slithering. "You think you can simply walk in and claim the Heart of the Realm? This is my domain, and you will perish here."Luna's face drained of color. "The Mistress of Shadows. I thought she was just a legend."The woman let out a cackle. "Legends are often born from truth. And now, your journey ends." With a wave of her hand, she summoned a horde of shadowy warriors, their weapons glinting with a deadly, black - edged light.The group readied themselves for battle, their hearts pounding in their chests. The crystal - key in Chen Jiuzhang's hand glowed brightly, but he could sense that this enemy was unlike any they had faced before. As the shadowy warriors charged, they knew that the true test of their strength and resolve had just begun.
