Rise of the Otherworld.

The group slowly descended the passage, which was filled with a damp smell, like the lingering decay of time. Faint fluorescent lights flickered on the walls, their light flickering like will-o'-the-wisp, providing some illumination but also making the passage seem even more eerie and mysterious. With every step, the stone slabs beneath their feet clunked, as if telling an ancient and mysterious story. The further they descended, the more mysterious the atmosphere grew, as if invisible eyes were watching them from the darkness, making them feel uneasy.

Zhang Hao walked in front, his posture erect as a pine tree, his longsword tightly gripped, the blade gleaming with a cold light. He vigilantly observed his surroundings, his eyes as sharp as a hawk's, not missing a single abnormality. "Everyone, be careful. This place doesn't feel right," he whispered, his voice echoing through the passage with a hint of tension. The voice seemed partially swallowed by the gloomy environment, sounding a little muffled.

Lingyu followed behind him, scanning the surroundings with sharp eyes, a hint of vigilance and curiosity in his gaze. "I wonder what's hidden in this basement. I hope it's not another crisis." His tone was a hint of fatigue. After all, he had been through so many battles in a row, and his body was beginning to show fatigue. But more than that, it was curiosity about the unknown that drove him forward.

As the mysterious man walked, he carefully observed the patterns on the wall, trying to find some clue. His eyes were focused and deep, as if he could see through the patterns into the mist of history. "These patterns seem to be a kind of rune, similar to those seen in the ruins and buildings before. Perhaps they hold a great secret about the ruins and the valley," he muttered to himself, his voice soft but remarkably clear in the silent passage.

The woman and the old man followed closely in the center of the group, spells condensed in their hands, ready to respond to any emergency. The old man frowned, his expression solemn, and said, "The spiritual energy fluctuations here are complex. I feel like a powerful force is sealed below. We must not be careless." His voice was low and hoarse, with the calmness of a man who had experienced many hardships. The woman nodded slightly, her eyes revealing a hint of nervousness, but she tried to remain calm.

As they descended deeper into the basement, a vast stone chamber emerged before them. The space was immense, resembling an ancient palace. In the center of the chamber stood a stone platform, crafted from an unknown black stone. Its surface, smooth as a mirror, reflected the fluorescent light from the walls. Atop this platform sat a faintly luminous crystal box. The crystal box, transparent as a mirror, seemed to contain a mysterious object, though the light obscured it from view. The light, like a dreamy veil, enveloped the contents of the box, adding a touch of mystery.

Just as everyone was about to approach the stone platform, a deep roar suddenly erupted from the corner of the stone chamber. The sound reverberated through the chamber like muffled thunder, jarring everyone's eardrums. A gigantic monster slowly emerged. It resembled a lion, but possessed three powerful tails, each thick and powerful, twisting like a giant python. Its body was covered in black scales, each gleaming with a metallic sheen, like an indestructible armor. Its eyes, like two blazing flames, glared at the group with vigilance and hostility, as if warning them to stay away.

"What kind of monster is this? How did it get here?" the woman exclaimed in surprise, a hint of fear in her voice. Her body trembled slightly, and the magic light in her hand also shook.

Zhang Hao quickly assumed a fighting stance, feet apart, planted firmly on the ground like a towering mountain. "Whatever it is, prepare for battle." He stared intently at the monster, mentally pondering a response. The creature looked formidable, and they had just fought the Nether Wolf, draining both their physical and spiritual energy. This battle was bound to be a difficult one. But there was no sign of retreat in his eyes, only unwavering determination.

The mysterious man stood beside Zhang Hao, his hands rapidly forming hand seals. Streams of spiritual energy flickered and danced at his fingertips. "Everyone, cooperate! I'll try to contain it with my magic first, while you look for opportunities to attack its weaknesses." He spoke calmly, his eyes revealing determination and confidence. He knew that in this situation, teamwork was crucial.

Ling Yu gripped his dagger tightly and circled to the monster's side, trying to find a flaw. His steps were light and agile, like a lurking cheetah, each step cautious yet full of power. His eyes were fixed on the monster's every move, waiting for the perfect moment to strike.

The monster seemed to sense the threat from the crowd. It roared, its voice shaking the walls of the stone chamber. Its three tails lashed out at the crowd like three steel whips. Wherever its tails passed, the air was torn apart, emitting a sharp whistling sound, as if it were being cut by a blade. This sudden attack plunged everyone into danger...
