Rise of the Otherworld.

A low roar emanating from the depths of the passage shook the entire space. The sound waves struck the stone walls, echoing dully as if the entire passage were groaning in pain. The mysterious man's expression instantly grew solemn, his once confident expression replaced by fear and nervousness.

The black-robed figure took advantage of the mysterious man's distraction to gather his magic power once more. His hands danced like a phantom, magic dancing and gathering at his fingertips. "Even if I die, I will make you pay!" The black-robed figure's voice was filled with anger and determination. His eyes were fixed on the mysterious man, ready to launch a new round of attack.

"What the hell is this?" the mysterious man muttered to himself, a hint of fear in his voice. His eyes involuntarily cast towards the depths of the passage, and the unknown roaring made him feel a chill in his heart.

Zhang Hao and the others remained unconscious, oblivious to the danger around them. They lay quietly on the ground, as if trapped in a terrible nightmare, unable to awaken. The woman's brow furrowed slightly, as if even in her dream she felt a sense of unease. The herbalist's breathing was heavy and even, oblivious to the impending danger. The old man's face was still tired and tense, as if everything he had just experienced was still weighing on his mind.

The black-robed man glared at the mysterious man. "Whatever it is, you brought this upon yourself!" His voice trembled, but it was filled with accusations and anger directed at the mysterious man. "If it weren't for you, we wouldn't be in this desperate situation!"

The mysterious man snorted coldly, "Stop talking nonsense and solve the crisis at hand first!" He pretended to be calm, but the panic in his eyes could not be concealed.

As the roar drew closer, a powerful pressure washed over them. Like an invisible wave, it suffocated them. Both the mysterious man and the black-robed figure involuntarily took a few steps back, their steps stumbling and nearly falling.

Suddenly, a massive figure burst forth from the darkness. Its form resembled a dragon, but it possessed sharp claws and enormous wings. Its scales shimmered with an eerie light. Each scale seemed a separate curse, making it unbearable to gaze directly upon. Its eyes, like blazing fireballs, radiated rage and a bloodlust. A suffocating aura emanated from its body, a breath that seemed to emanate from the depths of hell, filled with death and despair.

"This is..." The black-robed man's eyes widened, his face filled with shock. His voice became sharp with fear, as if an invisible hand was strangling his throat.

The mysterious man shouted, "Be careful, this monster is not easy to deal with!" His voice was trembling, but he still reacted quickly, quickly forming seals with his hands, trying to cast a powerful spell.

The monster opened its bloody maw and spewed out a stream of black flames. Like a giant black dragon, the flames bared its fangs and claws as it lunged at the mysterious man and the black-robed figure. Wherever the flames touched, the air was distorted and sizzled.

The mysterious man and the black-robed figure quickly dodged, their figures weaving in and out of the flames as if dancing on the brink of death. The flames instantly scorched the surrounding ground, leaving behind a black mark and emitting a pungent burnt smell.

The black-robed figure seized the opportunity to cast a powerful magic shield. The shield shone with a blue light, enveloping him like a giant bubble. It temporarily blocked the monster's attack. The flames collided with the shield, sending up countless sparks like fireworks blooming in the night sky.

The mysterious man was not to be outdone, and with his hands dancing, he released dark rays of light, which shot towards the monster. The rays were like black lightning, carrying the power of destruction.

The monster roared, waving its claws, scattering the rays of light one by one. Its power seemed boundless, and each attack made the entire passage tremble.

The two sides were locked in a fierce battle, while Zhang Hao and the others remained unconscious, their lives uncertain. Their bodies lay motionless on the ground, as if forgotten by the world. The mysterious figure and the black-robed figure in the battle had no time to spare them, and could only desperately resist the monster's attacks, hoping to survive this life-or-death struggle...
