The night was thick and inky, the moon hanging high in the sky, casting a cool, pale light that draped the earth in a mysterious silver veil. Zhu Xiang'er, Shi Linnan, and Shi Yuan hurried out of the secret garden, their steps quick and resolute. They knew time was of the essence; Uncle Lingji's life hung in the balance, and not a second could be wasted. As soon as they left the garden, they decided to immediately embark on their journey to find the Heart-Cleansing Grass.

Shi Linnan stood on the open grassland, looking up at the night sky. He cupped his hands to his mouth, took a deep breath, and let out a long, sharp whistle. The whistle pierced the silence of the night, echoing in the air. A short while later, a muffled whooshing sound grew louder as it approached. In the darkness, a huge black shadow rapidly flew towards them. As the shadow drew closer, by the moonlight, it became clear that it was a massive shadow dragon. Its wings, spread wide, resembled enormous black sails, each flap creating a powerful gust of wind. Its scales shimmered with a cold, eerie light in the moonlight, exuding a chilling majesty.

The Shadow Dragon slowly descended before the group, its massive claws gripping the ground firmly, raising a cloud of dust. "Quick, everyone get on!" Shi Linnan shouted, quickly climbing onto the dragon's back and settling comfortably behind its neck. Zhu Xiang'er, clutching her baby, carefully climbed up with Shi Yuan's help, finding a safe spot to sit and gripping the dragon's scales tightly. Shi Yuan was the last to leap onto the dragon, settling down beside Zhu Xiang'er.

"Go!" Shi Linnan gave the order, and the Shadow Dragon roared to the sky, its massive wings flapping violently as it instantly soared into the night sky. Zhu Xiang'er felt the wind whistling past her ears, the strong air currents making it hard for her to open her eyes. Instinctively, she hugged Xiao Zha tighter. Xiao Zha trembled in her arms, letting out weak whimpers.

Shi Yuan closed his eyes tightly, his brows furrowed, intently sensing the faint, almost imperceptible aura in the air. After a moment, he slowly opened his eyes, raised his hand, pointed in a certain direction in the night sky, and said firmly, "Over there, the Qingxin Grass should be in that direction." Shi Linnan nodded slightly, gently stroking the dragon's scales with both hands, softly guiding it to change its flight direction.

The Shadow Dragon soared through the night sky, shrouding the mountains, rivers, and forests below in darkness, with only a few faint lights flickering occasionally, adding to the mystery. Zhu Xiang'er gazed at the night below, her heart filled with both tension and anticipation. She was tense because they were about to face unknown dangers, and anticipating finding the Cleansing Grass as soon as possible, taking a crucial step towards saving Uncle Lingji.

As the flying dragon continued its advance, a towering cliff gradually emerged in the night. The cliff was steep and precipitous, like a sharp sword piercing the sky, its jagged rocks casting eerie shadows in the moonlight. "That's it," Shi Yuan murmured, a hint of excitement in his voice. Shi Linnan, controlling the Shadow Flying Dragon, slowly approached the cliff, landing on a relatively flat spot along its edge.

The three carefully slid down from the dragon's back and stood on the edge of the cliff. Looking at the steep precipice before them, a sense of tension welled up inside them. But they didn't hesitate. After exchanging a determined look, they began to climb along the path along the cliff edge. Zhu Xiang'er gripped Xiao Zha tightly, inching upwards step by step. Her breathing was rapid, her heart pounding, and every step was taken with extreme caution. Shi Linnan and Shi Yuan scouted ahead, using their keen observation skills to find safe footholds while keeping an eye out for any trace of the Qingxin Grass.

The night deepened, the moon had already set in the west, and its light grew increasingly cold. Zhu Xiang'er and her group struggled to climb the cliff, their clothes soaked with sweat, their arms and legs aching terribly. But they held only one belief in their hearts: to find the Cleansing Grass and save Uncle Lingji. Finally, after a long and arduous struggle, they reached a slightly larger platform.

"Found it!" Zhu Xiang'er suddenly shouted excitedly, her voice echoing in the night sky. She pointed to a crevice in the rocks at the corner of the platform, where a small grass emitting a faint glow swayed gently in the breeze. Shi Linnan and Shi Yuan rushed over and, upon closer inspection, confirmed it was the Qingxin Grass they had been searching for. A relieved smile appeared on Shi Linnan's face. He carefully picked the Qingxin Grass, placed it in a specially made wooden box, and stored it away carefully.

Meanwhile, not far behind Zhu Xiang'er and the others, Wu Dongzi was riding the enormous World-Eating Netherscale Python, silently following behind.

The World-Eating Scale Python exuded a chilling aura, its scales shimmering eerily in the moonlight. Its massive body undulated and undulated, like a black phantom traversing the night sky. Wu Dongzi clung tightly to the python's back, his eyes fixed on his companions ahead with a complex expression. His heart was filled with conflict; on one hand, he worried that Zhu Xiang'er and the others might be in danger, and on the other hand, he feared that their actions would affect his father, Wu Mai.

"I can't get too close, or I'll be in big trouble if they spot me," Wu Dongzi reminded himself silently. He controlled the World-Eating Netherscale Python, maintaining a safe distance from the Shadow Dragon. Moonlight shone on his face, revealing his furrowed brows and a hint of hesitation and helplessness in his eyes.

As the Shadow Dragon drew closer to the cliff, Wu Dongzi cautiously followed. He saw Zhu Xiang'er and her group dismount from the dragon's back and begin climbing the path along the cliff edge. In the moonlight, their small figures appeared exceptionally tiny against the steep cliff face, yet they exuded unwavering determination. Wu Dongzi's heart pounded; he watched them intently, fearing even the slightest mishap.

"Be careful," Wu Dongzi murmured to himself, his hands unconsciously tightening their grip on the scales of the World-Eating Netherscale Python. He knew that this cliff was fraught with danger, and a single misstep could result in certain death. He secretly resolved that if Zhu Xiang'er and the others were in danger, he would definitely lend a helping hand, even if it meant going against his father's wishes.

Time ticked by, and Zhu Xiang'er and her group struggled to climb the cliff. Wu Dongzi stood guard the entire time, not daring to blink. Finally, he saw Zhu Xiang'er excitedly point to a spot, and Shi Linnan and Shi Yuan also rushed over. Immediately, joyful smiles appeared on their faces. Wu Dongzi knew they must have found the Qingxin Grass.

"It seems they succeeded." Wu Dongzi felt a mix of emotions, happy for his companions' success but also worried about what would happen next. He watched as Zhu Xiang'er and her group returned to the Shadow Dragon with the Heart-Cleansing Grass, mounted the dragon again, and flew off into the distance. Wu Dongzi hesitated for a moment, then controlled the World-Eating Netherscale Python to follow.

As the Shadow Dragon raced through the night sky, a biting wind howled past, causing everyone's clothes to flutter wildly. Corpse Yuan sat atop the dragon's back, his hands gripping the scales tightly. A strange feeling suddenly welled up within him, fueled by his keen intuition. He instinctively turned his head, his gaze sweeping back and forth in the darkness, trying to catch a glimpse of anything unusual.

"What's wrong, Shi Yuan?" Zhu Xiang'er noticed Shi Yuan's unusual behavior and asked with concern.

Shi Yuan frowned, a hint of wariness flashing in his eyes, and said in a low voice, "I have a feeling that someone is following us, but I can't see who it is."

Upon hearing this, Shi Linnan turned his head sharply, his eyes wide, and looked behind him. "No way, who would be following us this late?" he said with a puzzled expression.

Zhu Xiang'er also tensed up, hugging Xiao Zha tightly in her arms, and said anxiously, "Could it be people from Wumai? Are they here to stop us from finding the treasure?"

Shi Yuan shook his head and said in a serious tone, "It's not clear yet, but we can't let our guard down. Everyone, be careful."

The Shadow Dragon seemed to sense its master's tension, increasing its speed as it flapped its massive wings powerfully, creating a strong gust of air. Corpse Yuan's gaze remained fixed on the rear, not missing a single subtle movement.

However, apart from the howling wind and the flapping of the dragon's wings, the night sky was completely silent. Shi Yuan felt increasingly uneasy; his intuition told him that the stalker was still nearby, but was too well hidden to be detected.

"Am I just imagining things?" Shi Yuan muttered to himself. But he quickly dismissed the idea. He always had great confidence in his intuition; the feeling of being watched was too strong to be a hallucination.

However, they found no suspicious signs along the way. Shi Yuan's doubts deepened. Who was that mysterious pursuer? Why was he following them? And why hadn't he shown himself?

"Whoever you are, you better not let me catch you," Shi Yuan vowed silently. He knew that they would have to be even more careful on their journey ahead, because the mysterious stalker might appear at the most unexpected time, causing them great trouble.
