Rise of the Otherworld.

The room shook more and more violently, as if the whole world was about to collapse. Huge rocks fell from the ceiling, and the cracks in the ground were like ferocious giant mouths, constantly swallowing everything. Lin Yu led the others to desperately shuttle between the falling rocks and the ever-widening cracks. Their figures seemed so small and determined in the chaos.

"Hurry up! Hurry up!" Lin Yu urged loudly, his voice almost drowned out by the roar. His forehead was covered with sweat, which slid down his cheeks and dripped onto the gravel under his feet. His eyes were filled with anxiety and determination. He held the sword tightly in his hand, clearing a way out for the disciples behind him.

Xiaoyaozi led the way, brandishing his magical weapon, emitting a brilliant light. Each swing shattered the incoming boulders into fragments. His clothes rustled in the wind, his hair disheveled, but his pace remained unwavering. "Follow me!" he shouted, his voice brimming with power.

One disciple stumbled with fear, his eyes filled with despair. "I... I can't do it anymore," his voice trembled, and his body fell backwards involuntarily.

"Hold me!" he cried desperately.

Lin Yu was quick to pull him back and hold his arm tightly. "Don't be afraid, I'm here!" Lin Yu said loudly, giving him courage and strength.

Just as they were about to reach the exit, a huge stone slab fell from the sky, blocking their way. The stone slab was so thick and heavy that it seemed like an insurmountable mountain.

"Let's fight!" Lin Yu roared, his whole body bursting with spiritual power. A powerful aura surged around his body, radiating light. He swung his sword at the stone slab, and the blade collided with the stone slab, making a sharp sound and sparks flying.

With everyone working together, they gathered all their strength together, and the stone slab finally couldn't bear it and shattered.

They filed out, the room behind them completely collapsing, sending up clouds of dust. A massive roar echoed in their ears, like a final threat to them.

"We're finally out." Everyone collapsed to the ground, gasping for breath. Their bodies were exhausted, but their hearts were filled with the joy of surviving the disaster.

Lin Yu looked at the ancient book in his arms, thinking. This ancient book was still closely guarded by him in such a dangerous situation, as if it was their hope for the future.

"Master, what should we do next?" Xiaoyaozi asked. His voice was a little tired, but more so, full of anticipation for the future.

Lin Yu stood up with a firm look in his eyes: "Let's find a safe place to study this ancient book first." His voice was steady and powerful, bringing a sense of peace of mind to everyone.

They found a secluded corner in the castle to rest for a while. This corner was relatively quiet, away from the noise and danger of the outside world.

Lin Yu gently opened the ancient book. The words on it were obscure and difficult to understand. Those ancient symbols and patterns seemed to hide endless secrets, waiting for them to uncover.

"What exactly is recorded here?" A disciple came over, his face full of confusion. He stared at the ancient book, trying to find some familiar clues.

Lin Yu shook his head: "It's not clear yet, but I feel there is a huge secret hidden in it." His fingers gently stroked the pages of the book, and he fell into deep thought.

Just as they were thinking hard, a burst of noisy footsteps suddenly came from outside. The footsteps were heavy and rapid, breaking the original tranquility.

"Oh no! Someone's coming!" Xiaoyaozi stood up alertly. His eyes instantly became sharp, and he clenched the magic weapon in his hand again.

Everyone's nerves were tense again, and the atmosphere became tense and depressing.

Who is this newcomer? Is he a friend or foe? What kind of crisis will they face? And can this mysterious ancient book be the key to their escape?
