Rise of the Otherworld.

The bird stood quietly on the stone, its gaze fixed on the crowd with a piercing gaze. It exuded a mysterious and majestic aura, making those present afraid to act rashly. Its pure white feathers shone brightly in the sunlight, like flawless snowflakes, each one radiating a sacred sheen.

Zhang Hao stared at the bird warily, then slowly stood up, sword tightly gripped. "What exactly are you doing here?" he demanded, his voice echoing through the valley, tinged with nervousness and confusion. His gaze was firm and sharp, as if he could see through the bird's exterior to its thoughts.

The bird didn't respond, but simply flapped its wings gently, stirring up a breeze. The breeze brushed against everyone's faces, bringing a touch of coolness, but also making them even more uneasy.

The woman tugged at Zhang Hao's clothes. "Be careful, this bird looks unusual." Her voice trembled slightly, and her eyes were filled with worry. She unconsciously clenched the magic wand in her hand, ready to deal with any danger that might arise.

The mysterious man took a few steps forward and observed the big bird carefully. "Maybe it means no harm." His eyes were deep and calm, trying to find clues from the big bird's actions.

Just as everyone was speculating, the bird suddenly raised its head and cried out. Its voice was clear and resonant, echoing throughout the valley. The cry seemed like a call from the ancient past, carrying a mysterious power that made everyone's heart tremble. Then, it spread its wings and took flight, circling in the air before soaring deeper into the valley.

"It seems to be leading us," the old man said. There was a hint of hesitation in his voice, but his eyes also sparkled with curiosity.

"No matter what, let's follow and see." Zhang Hao made up his mind. His eyes were firm, as if he was ready to face anything.

The group advanced in the direction the bird had flown. The path through the valley was rugged and overgrown with weeds. The stones beneath their feet were uneven, and thorns occasionally scratched their clothes. But they did not retreat, their hearts filled with curiosity and anticipation for the unknown.

After walking for a while, they came to a cliff. A large bird was perched on a tree above the cliff. It looked at them quietly, with a look of expectation in its eyes.

Zhang Hao and his companions approached the mountain wall and discovered some strange symbols and patterns carved on it. The symbols had smooth lines and the patterns were exquisite and complex, as if they contained endless mysteries.

"What is this?" the herbalist asked doubtfully, his eyes wide open, trying to discern any clues from the symbols.

The mysterious man walked forward and studied the symbols carefully. "It looks like some kind of ancient relic." His fingers gently touched the symbols, feeling the power contained in them.

At this moment, the symbols on the mountain wall suddenly flickered, and a stone door slowly opened. The stone door was heavy and ancient, and it made a creaking sound, as if telling of the vicissitudes of time.

Everyone looked at each other, hesitating whether to go in. Their hearts were filled with fear of the unknown, but also with a desire for treasures and secrets.

"Since we're already here, why not go in and take a look?" Zhang Hao said. He took a deep breath and walked into the stone gate first.

They walked through the stone gate, revealing a spacious cavern surrounded by a variety of ancient artifacts and magical treasures. The artifacts radiated a mysterious light, some crystal clear, others ancient and heavy. The magical treasures shimmered with a strange light, dazzling the eyes.

"Are these treasures?" the little girl asked in surprise. Her eyes sparkled with excitement, and she couldn't help but reach out to touch them.

However, before they could take a closer look, a deep roar suddenly erupted from the cave. It sounded like it came from the depths of hell, filled with endless rage and majesty. Everyone's faces instantly turned pale, and their hearts were filled with fear.

"Be careful!" Zhang Hao shouted loudly.

A huge figure slowly emerged from the darkness...
