Rise of the Otherworld.

Just as everyone was at their wit's end, Lin Yu forced himself to calm down and carefully observed the ever-changing runes on the crystal ball. His eyes were focused and sharp, not missing any subtle clues. The sweat on his forehead slid down his cheeks and dripped onto the ground, but he was completely unaware.

"Everyone, don't panic. This rune change may be the key." Lin Yu said loudly, trying to calm everyone's emotions. His voice echoed in the empty room, carrying a reassuring power.

Xiaoyaozi also came over to study the mysterious runes. "Master, I think these runes seem to be arranged according to a certain pattern." He stared at the runes, his brow furrowed, and fell into deep thought.

Lin Yu nodded slightly, "Yes, we must find this pattern before we can find a way to crack it." His fingers gently touched the crystal ball, feeling the faint fluctuations of spiritual power, and constantly calculating the possible permutations and combinations in his mind.

At this moment, the disciple trapped in the crystal ball was already on the verge of death, his voice becoming extremely weak. "Master...save me..." The voice seemed to come from a distant place, filled with endless pain and despair.

Lin Yu's heart tightened, and he sped up his thinking. His brain was working rapidly, and various ideas intertwined and collided in his mind. Suddenly, he had a flash of inspiration.

"I understand! The changes in these runes are related to the fluctuations of our spiritual power." Lin Yu said. His voice was full of excitement and hope, and his eyes became brighter.

He immediately instructed everyone to adjust the output frequency and intensity of spiritual power, and resonate with the crystal ball according to a specific rhythm. "Everyone listen to my command, don't panic, keep the rhythm." Lin Yu's voice was steady and powerful, which gradually calmed everyone's panic.

As everyone's spiritual energy adjusted, the light around the crystal ball began to become unstable. Sometimes it was bright, sometimes dim, as if struggling to resist. The powerful suction force also gradually weakened, and the trapped disciple's body was no longer tightly attached to the crystal ball.

"Try harder!" Lin Yu shouted. His voice became a little hoarse due to nervousness, but it was still full of encouraging power.

Everyone gritted their teeth and cooperated with all their might. Their faces were covered in sweat, their clothes were already soaked with perspiration, but no one slacked off. Everyone prayed silently in their hearts, hoping to successfully rescue their companions.

Finally, the disciple fell from the crystal ball. His body hit the ground heavily with a dull sound.

"Quick, give him the pill!" Lin Yu said hurriedly. He quickly took out a bottle of precious pills from his arms, poured out a pill, and stuffed it into the disciple's mouth.

After the disciple took the elixir, his complexion gradually improved. His breathing became steady, and his eyes, which had been tightly closed, slowly opened.

"That was a close call, it was almost..." a disciple said with lingering fear. He wiped the sweat from his forehead, his body still trembling slightly.

Lin Yu looked at the crystal ball and said, "The secret of this crystal ball has not been fully revealed yet, everyone be careful." His eyes were full of vigilance, and the sword in his hand was still tightly grasped.

Just as they were about to examine the crystal ball further, a deep roar suddenly erupted from the room. It sounded like the roar of an ancient beast, filled with rage and majesty. The entire room trembled slightly at the sound, and dust fell from the walls.

"What's that sound?" a disciple asked in horror.

Lin Yu frowned, "I don't know, but he's definitely not a good guy. Everyone, stand back to back and get ready for battle."

As the roar grew closer, a powerful pressure came over them. Everyone's heartbeats accelerated, and a tense atmosphere filled the room.

What exactly is this unknown existence? Can they escape danger once again?
