Rise of the Otherworld.

Zhang Hao streaked towards the cave master like a meteor, his sword gleaming brilliantly. His gaze was unwavering, revealing a determination to face death head-on. The cave master's blood-red eyes fixed on Zhang Hao, a deep growl emanating from his lips. He waved his massive arms in an attempt to block Zhang Hao's attack. His arms whipped up a gust of wind, rustling Zhang Hao's clothes.

At this critical moment, Zhang Hao dodged the cave master's attack with a deft movement, his sword thrust straight at the cave master's heart. However, the cave master's reaction was also extremely fast. Just as the sword was about to penetrate, he slightly tilted his body, and the sword only struck his shoulder. The sword collided with the cave master's hard body, sparking a series of dazzling sparks.

"Roar!" The cave master roared in pain, his voice echoing through the cave, making everyone's ears ring. His attacks became more frantic and fierce, each swing of his arms carrying the force of a tsunami. The immense force made the entire cave tremble, and rocks fell like rain.

The woman anxiously called out, "Zhang Hao, be careful!" Her voice was filled with concern and worry, her heart in her throat. Her hands were clenched tightly together, her knuckles white with tension.

Zhang Hao didn't flinch. He gritted his teeth and swung his sword again, striking the cave master. This time, he channeled the power of his inheritance into the sword, emitting a dazzling light that seemed to rip through all darkness. The light illuminated Zhang Hao's resolute face, his expression filled with determination.

Seeing the situation was dire, the cave master tried to retreat, but Zhang Hao was too fast. The sword struck the cave master fiercely, leaving a deep wound. Green blood gushed out, splashing all over Zhang Hao, making him look like a blood-soaked war god.

"Great, Zhang Hao!" the herbalist shouted excitedly, hope rekindled in his eyes. His voice became hoarse with excitement, and his face was full of excitement.

The cave master was seriously injured, and his movements became sluggish. The old man took the opportunity to cast a powerful spell, and beams of light flew towards the cave master, restricting his movements. The light was like a rope, tightly wrapped around the cave master's body, making it difficult for him to move.

The black-robed man was not to be outdone. He poured all his magic power into his staff, and a powerful energy beam shot out from the tip of the staff, hitting the cave master's head. The cave master's head shook and his eyes became blurry.

Under the combined attack of the crowd, the cave master was on the verge of collapse. It roared one last time and tried to make a final struggle. But its strength had been exhausted, and its movements seemed weak and clumsy.

Zhang Hao seized the opportunity and charged forward again, thrusting his sword straight into the cave master's heart. This time, the cave master could no longer dodge, and the sword pierced deeply into his heart. The cave master's body trembled violently, then collapsed to the ground with a thud, raising a cloud of dust that filled the air for a long time.

Everyone breathed a sigh of relief as they watched the fallen cave master collapse, their bodies already stretched to their limits, each covered in wounds.

"It's finally over..." the woman said weakly. Her voice was almost inaudible, and her face was filled with exhaustion from surviving a catastrophe.

Zhang Hao was also breathing heavily, "But we can't relax yet, we have to leave here quickly." Although his voice was weak, he still maintained a hint of vigilance.

At this moment, a strange light suddenly emanated from the cave master's corpse. The light was very weak at first, but soon became stronger, illuminating the entire cave as bright as day.

"What's going on?" asked the herbalist in horror.

Zhang Hao frowned, "Be careful, there might be more unexpected events."

Amidst the light, the cave master's corpse began to change, gradually shrinking until it transformed into a black sphere. Mysterious runes shone on the sphere, emitting a terrifying aura.

"Could this be the core of the cave master?" the old man guessed.

Before everyone could react, the black sphere suddenly exploded, and a powerful energy impact spread in all directions.

"Not good!" Zhang Hao shouted, trying to use his sword to block the energy.

But the energy was too strong, instantly knocking everyone away. Their bodies were like leaves falling in the wind under the impact of the energy...
