Rise of the Otherworld.

Powerful spells surged like a raging torrent, attacking the giant metal bat's chest core. In an instant, a blazing light illuminated the entire valley, as if day had arrived prematurely. The glare was so intense it was almost impossible to gaze directly upon. As if sensing the mortal threat, the giant metal bat let out a shrill roar, a cry like the wail of a night owl, echoing through the valley, filled with rage and terror. Its wings flapped frantically, stirring up a gust of wind that threatened to counteract the combined might of the crowd's spells.

Zhang Hao's spiritual sword energy arrived first. With a thunderous roar, like a bolt from the blue, the sword energy struck the core with a powerful impact, igniting a dazzling burst of light. Tiny cracks instantly appeared in the metal shell surrounding the core, spreading rapidly like a spider web. The light flickered, as if threatened to die at any moment. Then, the mysterious man's massive earth spikes, controlled by a massive force, pierced the core with overwhelming force. With a crack, the cracks in the metal shell multiplied exponentially, and the once solid metal seemed as fragile as glass.

Ling Yu's swarm of wind blades followed closely behind, like a group of well-trained assassins, each blade precisely slicing through the metal surrounding the core. The friction between the wind blades and the metal sent forth countless dazzling sparks, which, illuminated by the light, resembled a dazzling fireworks display. These wind blades further exacerbated the damage to the metal shell, weakening the protection around the core even further. The woman's ice spikes, like rows of sharp spears, pierced the cracks around the core with a biting chill. Wherever the ice spikes touched, the metal quickly froze, and the chill spread rapidly, making the metal even more fragile, as if the slightest bend would break.

The old man's lightning bolt finally struck the core. Like a raging dragon, the powerful current instantly pierced the giant metal bat's body. Its body trembled violently, and it let out a painful roar that echoed through the valley, filled with resentment and despair. Under the ravages of the lightning, the glow at the core gradually dimmed. The core, once radiating mysterious power, now faltered like a candle about to go out.

The giant metal bat's wings drooped limply, its body teetering on the brink of collapse. But its dignity as a leader and its instinct for survival kept it from giving up, attempting a final struggle. It flapped its wings vigorously and lunged towards the group. Though not as swift as before, it still carried a powerful impact, as if it intended to drag them all into the abyss along with it.

Zhang Hao's eyes instantly hardened upon seeing this. Without hesitation, he once again concentrated all his spiritual energy, unleashing his full potential. With a roar, he unleashed another stream of spiritual sword energy. Like a meteor, it trailed a long tail, hurtling straight towards the core of the giant metal bat. This time, the sword energy carried a desperate determination, even more powerful than before, as if condensed with all of Zhang Hao's faith and strength.

The moment the sword energy struck the core, the metal shell could no longer withstand the relentless onslaught, shattering with a resounding boom. The core, exposed to the air, its light extinguished, like a falling star. The giant metal bat let out a final, mournful wail, a farewell to the world, filled with an endless desolation. Its body, freed from support, fell heavily to the ground like a crumbling mountain, sending up a vast cloud of dust. The dust rose, filling the entire valley, as if a grand and tragic funeral were being held for the once-mighty giant metal bat.

With the fall of the giant metal bat leader, the remaining metal bats instantly lost their will to attack, like an army without a backbone, becoming distraught. They scattered in all directions, like frightened birds, disappearing into the mist. Peace finally returned to the valley, leaving only the exhausted but relieved figures. The calm atmosphere formed a stark contrast to the fierce battle just now.

"Finally succeeded," Ling Yu panted, his voice filled with the relief and joy of surviving a disaster, and a gratified smile appeared on his face. Against the backdrop of sweat and dust, that smile seemed particularly sincere.

"Yes, this battle was not easy," the woman said with emotion, wiping the sweat from her forehead. Her eyes revealed a hint of fatigue, but more of the pride of defeating a powerful enemy.

Zhang Hao looked at the crowd, his heart filled with gratitude. "Thanks to everyone's concerted efforts, it would have been difficult for us to defeat this giant metal bat." His voice was filled with respect, and his gaze lingered on each of his companions, as if to deeply imprint this friendship in his heart.

The mysterious man nodded and said, "But we can't let our guard down. There may be more dangers waiting for us ahead." His eyes were still vigilantly looking into the depths of the valley, like an experienced hunter, always ready to face unknown challenges.

Everyone agreed, and after a brief rest, they continued their journey deeper into the valley. They didn't know what lay ahead, but after this battle, their confidence was strengthened. They believed that as long as they united as one, they could overcome all difficulties. Their steps were firm and powerful, as if proclaiming their fearlessness and determination in the face of unknown dangers...
