Rise of the Otherworld.

Under the concentrated firepower of the crowd, the cracks at the edge of the black hole gradually widened, and the dark aura became chaotic. The black hole, which had seemed indestructible, now began to show signs of collapse like a broken mirror.

Lin Yu felt victory was in sight, and he shouted loudly: "Try harder, we will succeed!" Sweat kept flowing down his cheeks, but he didn't bother to wipe it off. His eyes were full of anticipation and tension, staring at the ever-widening crack, as if it was a passage to hope.

The disciples gritted their teeth, pouring all their remaining spiritual energy into their attacks. Their faces were as pale as paper, but their eyes burned with a determined fire. The light of their spells grew increasingly dazzling, like sharp swords piercing the cracks of the black hole. Each ray of light contained their determination and courage, and each attack was their desire for survival and a challenge to the unknown.

Finally, with a resounding, earth-shattering roar, the black hole began to collapse. In that instant, it felt as if the entire world had plunged into chaos. The powerful impact, like a surging wave, toppled everyone to the ground. Their bodies tumbled across the ground, crashing into the surrounding walls and objects.

"Success! We succeeded!" a disciple shouted excitedly. His voice was hoarse with excitement, and his face was filled with the joy of surviving a disaster and the pride of victory. He struggled to get up from the ground, wanting to cheer, but his fatigue made his movements seem a little unsteady.

However, before they could celebrate, a mysterious force suddenly surged in the room, enveloping everyone. This force was invisible and colorless, but like sticky glue, it made people feel extremely oppressive and constrained.

Lin Yu's heart tightened, "Everyone be careful!" His voice was full of vigilance and worry. He tried to struggle to stand up, but the force pressed tightly on him, making his movements extremely difficult.

"What is this?" Xiaoyaozi frowned, his face filled with confusion and vigilance. He looked around, trying to find the source of this power, but there was nothing around except the gradually dissipating dark aura.

Lin Yu tried hard to break free from the restraints of this force, but found that he could not move at all. His body seemed to be pressed down by an invisible mountain, and every inch of his muscle was under tremendous pressure. His breathing became rapid and heavy, and the sound of his heartbeat was particularly clear in the silent room.

Just when everyone was feeling hopeless, Lin Yu's sword suddenly emitted a soft light. The light was like a faint candlelight at first, but in an instant it became bright and warm. The light gradually spread, competing with the mysterious power.

"This sword..." A glimmer of hope surged in Lin Yu's heart. He stared at the sword intently, as if he could find the answer to his liberation from the light.

Under the resistance of the sword's radiance, the mysterious force gradually weakened. The suffocating pressure began to ease, and everyone was finally able to escape. They collapsed to the ground, gasping for breath, as if they had just experienced a life-and-death battle.

"Master, what should we do next?" a disciple asked weakly. His eyes were filled with confusion and fatigue, and he was obviously exhausted by this series of crises.

Lin Yu looked at his sword and said thoughtfully: "The secrets in this castle are probably far beyond our imagination. We continue to explore and must find the truth." His voice was weak, but full of determination.

Can they successfully uncover the mystery of the castle? What kind of adventures await them? And what secrets does the sword that suddenly began to work wonders hide?
