Rise of the Otherworld.

However, before they could celebrate, a strange sound suddenly emanated from all around them. It was like the wails of countless vengeful spirits, piercing and eerie, terrifying. It seemed to emanate from the depths of the Netherworld, carrying with it endless resentment and pain, piercing the depths of everyone's soul.

"What is this?" The black-robed man looked around in horror, his voice sharp with fear, and the weapon in his hand trembled unconsciously. His eyes were wide, filled with fear and uneasiness of the unknown.

Zhang Hao's brow furrowed. "Be careful, there might be some unknown danger." His voice was low and firm. Although he was filled with doubts, he knew he couldn't panic at this moment. His eyes scanned the surroundings sharply, trying to find the source of the sound.

At this moment, the once clear sky quickly turned gloomy, dark clouds thickened, and a fierce wind blew. Like an enraged dragon, the wind roared and swept through, rustling everyone's clothes. The wind seemed to be mingled with some evil force, and every breath felt like a cold blade, scratching painfully on the face.

"Oh no! This force is too strong!" the old man said with difficulty. His voice was faint in the strong wind, but his eyes remained firm. He gripped his staff tightly, trying to resist this evil force.

Amidst the raging wind, dark shadows gradually emerged. These shadows varied in form: some resembled human forms, yet twisted and deformed; others resembled beasts, their fangs gleaming with ferocious fur. They all exuded a strong, sinister aura, like demons crawling from the depths of hell.

Zhang Hao gripped his sword tightly. "Prepare for battle!" His voice boomed like a bell, brimming with courage and determination. He stood firm in the raging wind, like an unshakable mountain.

The shadows quickly lunged at them. Zhang Hao was the first to meet them, his sword wielding in the wind, emitting streaks of cold light. Each swing of his sword carried with it immense strength and unwavering conviction. The sword collided with the shadows, producing a sharp sound and sending sparks flying.

The old man cast another spell, offering protection for the group. He muttered something, and the gem on his staff shone faintly. But his mana was already depleted from the previous battle, and the spell's effectiveness was greatly reduced. His face was filled with fatigue, but he gritted his teeth and persevered.

The black-robed man and the herbalist also fought hard. The black-robed man weaved through the shadows, his weapon constantly attacking them, each strike using all his might. The herbalist assisted, throwing herbs in his hand to try to slow the shadows' movements.

But the shadows grew in number, and the group gradually fell into trouble. Their strength was constantly depleting, and their movements became slower and slower.

"This won't work. We have to find their weakness!" Zhang Hao shouted. His voice was hoarse from the battle, but still full of power.

At this moment, he discovered that these shadows would retreat briefly when they encountered strong light. Although that momentary retreat was short-lived, it gave him a glimmer of hope.

"Everyone, concentrate your strength to create strong light!" Zhang Hao shouted while resisting the attack of the black shadow.

Everyone unleashed their respective abilities, attempting to generate a powerful light. The elder channeled his final magical power into his staff, causing it to emit a dazzling glow. The black-robed figure brandished his weapon, which shimmered with a strange light. The herbalist tossed a special herb, which ignited and shone brightly. For a moment, the various lights intertwined, illuminating the dark area.

The shadows were indeed affected, and the pace of their attacks slowed down.

Zhang Hao took the opportunity to lead the others in a counterattack. Their attacks were more fierce and resolute. Each attack was carried out with the determination to kill, trying to break through the encirclement of the black shadows.

But just as they thought victory was imminent, a massive black shadow appeared in the sky. Its body was immense, obscuring the sky and blocking out the sun. Its aura was more powerful than any previous shadow, as if it were the master of darkness.

"What...what should I do?" the herbalist's voice trembled. His legs felt weak, and he could barely stand.

Zhang Hao took a deep breath and said, "Don't be afraid, we will face it together!" He looked at the huge black shadow in the sky with a firm gaze, without any thought of retreating in his heart.

Everyone regained their spirits, and the flame of hope rekindled in their eyes. They huddled together, ready to face this final challenge...
