Rise of the Otherworld.

The low roar echoed in the cave, making everyone's heart tremble. Every impact of the sound wave was like a heavy hammer, hitting their hearts hard. Lin Yu held the sword tightly in his hand, his palms were full of sweat, but his eyes were still firm and vigilant, staring at the depths of the cave.

"Everyone be careful, there may be danger approaching." Lin Yu said in a low voice. Although his voice was not loud, it was clearly heard by everyone.

The disciples stood up and gathered around Lin Yu, their expressions tense. Their breathing became rapid, and their heartbeats were particularly clear in the silent cave. Some of them trembled slightly with their weapons, showing their inner fear.

At this moment, a powerful aura surged from the depths of the cave, bringing with it a suffocating feeling of oppression. It was like an invisible dark cloud that instantly enveloped everyone, making it difficult for them to breathe and their bodies felt heavy.

"This aura... is so powerful!" Xiaoyaozi's face was solemn, his brows were tightly furrowed, and his eyes were full of worry.

As the aura drew closer, a gigantic figure gradually emerged from the darkness. It was as tall as a mountain, and every step forward made the ground tremble slightly.

"What kind of monster is this?" a disciple's voice trembled. His voice was filled with fear, and his legs involuntarily weakened.

The monster was enormous, like a small mountain, and covered in hard scales. Those scales shone eerily in the darkness, like sharp blades. Its eyes were like two giant lanterns, emitting a ferocious light that made people afraid to look directly at it.

The monster approached step by step, its heavy footsteps echoing in the cave, like a countdown to death. Everyone retreated unconsciously, stumbling, their backs pressed tightly against the cold cave wall.

"Don't be afraid, let's go together!" Lin Yu shouted and rushed forward first. His figure was like a flash of lightning, instantly leaping into the darkness.

He swung his sword at the monster, the blade colliding with the monster's scales, sending out a string of sparks. The sparks bloomed in the darkness for a moment, then quickly extinguished.

The monster roared and swung its thick claws towards Lin Yu. The claws made a whirring sound, as if they could smash everything into pieces.

Lin Yu dodged sideways nimbly and stabbed the monster with his sword again. His movements were smooth and there was no hesitation at all.

The other disciples also unleashed their own spells. For a moment, the cave glowed with light. Fire, frost, and lightning intertwined, creating a dazzling yet dangerous scene. Various attacks landed on the monster, crackling with sounds.

However, the monster didn't seem to be seriously hurt, its body only trembling slightly before its attack became even more fierce. It opened its bloody mouth and spewed out a black smoke that quickly spread, carrying a pungent smell.

One disciple was unable to dodge and was knocked away by the monster, hitting the cave wall hard. His body slid down and fell to the ground, spitting blood from his mouth.

"Hold on!" Lin Yu shouted loudly. His voice was full of anxiety and anger.

Xiaoyaozi formed seals with his hands and cast a powerful spell. A beam of ice-blue light shot towards the monster. The light was like an ice arrow, carrying a biting chill.

The monster was struck by the light and paused for a moment. A thin layer of frost formed on its body, but it was quickly shattered by the powerful force.

Lin Yu took the opportunity to attack again. He flew up and pointed his sword at the monster's eyes.

In this fierce battle, can they find the monster's weakness and successfully defeat this terrifying existence?
