Rise of the Otherworld.

As the powerful aura approached, everyone's faces turned pale. Zhang Hao gripped his sword tightly, his arm trembling slightly with nervousness. His eyes were fixed on the darkness ahead, as if he could see through it to the horror that was about to emerge.

"What the hell is this?" The woman's voice was filled with fear and anxiety. Her voice was trembling, and her hands unconsciously hugged her body tightly, trying to gain a sense of security.

The ground shook more and more intensely, like a mighty army galloping towards them. A massive shadow gradually emerged from the darkness. Each tremor sent rubble cascading down from the cavern, like the prelude to the end of the world.

The herbalist's legs went weak and he almost collapsed to the ground. "Are we going to die here?" His voice was tearful and his eyes were full of despair and helplessness, as if he had seen the end of his life.

The old man tried to remain calm and said, "Don't panic, let's take a look at the situation first." Although his voice was relatively steady, his slightly trembling hands betrayed his inner fear.

The shadow gradually became clearer, revealing itself to be an immense, two-headed dragon. Its body was the size of a small mountain, and its two heads spewed fire and ice, distorting the surrounding air. The intertwined glow of ice and fire illuminated the entire cave, illuminating the terrified faces of the crowd with remarkable clarity.

"This... How can we possibly defeat this?" the black-robed man said in despair. His staff slipped from his hand, and he stared blankly at the terrifying dragon, as if he had lost his soul.

Zhang Hao gritted his teeth and said, "No matter what, let's fight!" He rushed forward first. His figure seemed so small in front of the dragon, but his courage was like a burning flame, undimmed.

The woman mustered her courage and cast another spell, sending a beam of light towards the dragon. Her eyes were determined. Although her heart was filled with fear, she chose to fight for her life.

However, these attacks were like tickling the dragon. With a flick of its tail, Zhang Hao was sent flying, crashing into the cave wall and spitting out a mouthful of blood. His body left a deep mark on the cave wall before he slid down helplessly.

Before the woman's magic light could even reach the dragon, it was engulfed by the flames that spewed from its mouth. The flames spread instantly, and the woman had to quickly retreat to avoid being burned.

Seeing this, the old man quickly cast a defensive spell, trying to buy some time for everyone. His forehead was covered with sweat, and each time he cast a spell, it seemed extremely difficult, but he still did not give up.

"This isn't going to work!" the herbalist cried anxiously. He paced back and forth, feeling anxious and helpless.

Just as everyone was in despair, Zhang Hao suddenly discovered an old wound on the dragon's body, which seemed to be left by a previous battle. Although the old wound had healed partially, it still looked a little fragile.

"Attack its old wound!" Zhang Hao shouted. His voice was hoarse from injury, but full of hope.

Upon hearing this, everyone focused their attacks on the dragon's old wounds. The light from various spells and weapons converged together, forming a powerful force.

The dragon roared in agony, attacking them even more frantically. Suddenly, the cavern was ablaze with flying sand and rubble, a dangerous scene. Huge rocks fell from the ceiling, and flames and frost raged through the cavern.

The black-robed man used up his last bit of magic power and unleashed a powerful spell, striking the dragon's old wound. The dragon's movements slowed slightly, and its roar was filled with pain and anger.

Zhang Hao took the opportunity to leap up and plunge the sword in his hand straight into the dragon's old wound. He used all his strength to thrust the sword deep into the dragon's body.

The dragon let out a shrill cry and fell to the ground, its body twitching continuously. The icy and fiery light on its body gradually disappeared, and darkness returned to the cave.

Everyone collapsed to the ground exhausted, gasping for breath. Their bodies had reached their limit, and every breath was accompanied by severe pain.

"Is it finally...over?" the woman said weakly. Her voice was so faint in the darkness that it seemed as if it would fade away at any moment.

Before anyone could recover from their shock, a deep roar erupted from the depths of the cave. This roar was even deeper and more terrifying than the dragon's roar before, as if it came from the depths of hell.

Everyone's faces turned paler in an instant, and the glimmer of hope that had just ignited was instantly shattered.

"What...what is this?" The herbalist's voice was filled with endless fear, and he almost cried.

Zhang Hao struggled to stand up and said, "No matter what it is, we have to face it." His voice was weak but full of determination.

The old man also forced himself to stand up, "Everyone get ready, this may be the final challenge."

In the darkness, that unknown terrifying existence is gradually approaching...
