Rise of the Otherworld.

The strange sound echoed continuously in the cave, like a call from the abyss, making people tremble with fear. Each sound was like a heavy hammer hitting everyone's heart, rippling with fear.

Zhang Haoqiang braced himself, signaling everyone to remain silent and listen carefully to the source and pattern of the sound. His eyes were firm and focused. Although his body was extremely exhausted, his will was as strong as steel.

"This sound seems to have a certain rhythm, not like an ordinary beast's roar," Mo Ying whispered. His voice was particularly clear in the silent cave, carrying a hint of doubt and uneasiness.

Feng Wuhen wiped the blood from the corner of his mouth and said, "Is there something more terrifying in this cave?" His voice trembled. The fierce battle with the monster just now had already seriously injured him. Now facing this unknown mysterious voice, his heart was filled with fear.

The woman gripped her dagger tightly, her eyes filled with vigilance. Her breathing was rapid, and her heartbeat was particularly loud in the quiet environment.

As they approached the source of the sound, a powerful pressure came over them, making it almost impossible to breathe. This pressure was like an invisible hand, tightly strangling their throats, making every step forward extremely difficult.

"Everyone, be careful!" Zhang Hao warned. His voice was steady and powerful, trying to give everyone a sense of security.

At this moment, the voice suddenly became clear, as if telling something, the tone rising and falling, full of mysterious rhythm.

"It seems to be a language, but I don't understand it." A disciple was confused. He frowned and tried hard to understand this strange sound.

Zhang Hao calmed down and tried to capture useful information from the chaotic sound. He closed his eyes and immersed his mind in this ocean of sound, carefully feeling every subtle change in it.

Suddenly, a flash of inspiration flashed in his mind.

"Perhaps this is an ancient spell, guiding us somewhere," Zhang Hao said. There was a hint of uncertainty in his voice, but more of a desire to explore.

Everyone looked at each other, unsure whether to believe this speculation. After all, all of this was too mysterious and unknown, full of unpredictable dangers.

But now they had no other choice but to follow the mysterious voice and continue forward. Every step was filled with hesitation and fear, but also with a hint of curiosity and anticipation about the unknown.

The cave passage became increasingly narrow, the rock walls on either side squeezing their bodies, making it nearly impossible for them to turn around. The light also grew dimmer, practically pitch-black.

"Everyone, don't get separated." Mo Ying's voice echoed in the darkness. His voice was filled with a hint of anxiety, afraid of losing his companions in the darkness.

At this moment, a faint light appeared in front of them. The light was like a star in the dark night, although weak, it brought them endless hope.

"What is that?" the woman asked in surprise, her voice filled with surprise and confusion.

Everyone quickened their pace, heading towards the light. Their steps seemed hurried and chaotic in the darkness, their hearts filled with desire to understand the secret behind the light.

As they approached, they discovered a cave emitting a mysterious light. A layer of light mist hung over the entrance of the cave, making it difficult to see what was inside.

Something important seemed to be hidden in the cave. The light waxed and waned, as if breathing, full of the rhythm of life.

Just as they were about to enter the cave to explore, they heard a noisy sound of footsteps behind them. The footsteps sounded heavy and rapid, as if a group of people were rushing towards them.

"Oh no, someone is chasing us!" Feng Wuhen exclaimed.

Zhang Hao frowned, "Go into the cave first!"

Everyone rushed into the cave without hesitation, and the light instantly enveloped them...

However, after entering the cave, they discovered that the situation inside was far more complicated and dangerous than they had imagined...
