Rise of the Otherworld.

The crystal ball suddenly blazed brightly, illuminating the entire hall like daylight. The intense light caused Zhang Hao and the others to subconsciously squint and shield their eyes with their hands. The light surged like a surging tide, wave after wave, stinging their eyes painfully.

When the light faded slightly, they could see some images flickering inside the crystal ball. The images were like ripples in water, blurry and unclear, yet full of mysterious attraction.

Zhang Hao approached the crystal ball, hoping to get a better look at its contents. The image showed a desolate battlefield, countless soldiers engaged in a fierce battle, their cries of slaughter deafening. The air was thick with blood, and the steeds of war raged. He could almost smell the pungent scent of blood.

"What is this?" the black-robed man asked doubtfully. His voice echoed in the empty hall, trembling and confused.

The old man stared at the crystal ball with a serious expression, "This is probably a piece of history that has been forgotten." His eyes were deep, as if he could see through the image to the distant past.

At that moment, the image in the crystal ball suddenly shifted. The battlefield vanished, replaced by an ancient castle. The castle's gates were tightly shut, and a dark atmosphere permeated the air. The castle's walls towered into the clouds, eerie and terrifying, as if telling of endless secrets and curses.

The herbalist couldn't help but shudder. "There's an evil spirit in this place." His voice was full of fear, and his body involuntarily stepped back.

Zhang Hao frowned, "No matter what, let's first see what the secret of this crystal ball is." His eyes were firm. Although his heart was full of uneasiness, his curiosity drove him to find out.

When he reached out to the crystal ball again, a powerful suction force came and sucked his hand tightly onto it. The suction force was like an invisible giant hand, holding him tightly, making it impossible for him to break free.

"Zhang Hao!" the others exclaimed, their voices filled with fear and worry as they rushed forward to help.

Zhang Hao tried to break free, but found himself unable to move at all. It was as if the crystal ball was continuously sucking away his strength. He could feel his vitality slipping away bit by bit, and his body became weaker and weaker.

The old man hurriedly cast a spell, attempting to break the crystal ball's suction. He muttered something, his staff flashing with dazzling light. Like a bolt of lightning, the magic light shot towards the crystal ball. But upon contact, it vanished without a trace, as if swallowed by a vast black hole.

"What should I do?" The black-robed man paced back and forth anxiously. His footsteps made a clattering sound on the ground, revealing his inner restlessness and anxiety.

The herbalist stood there, bewildered, stamping his feet anxiously. His hands were clenched tightly, and beads of sweat appeared on his forehead.

As his strength continued to drain away, Zhang Hao's face became paler and paler. His lips lost their color, and his eyes became blurry.

Just as everyone was feeling hopeless, the ancient book on Zhang Hao's body suddenly flew out of its own accord, hovering above the crystal ball. The book emitted a soft glow, intertwining with the light of the crystal ball. The light was like a beautiful dance of light, like a dream.

Gradually, the crystal ball's suction began to weaken, and Zhang Hao finally broke free. He collapsed to the ground, gasping for breath, as if he had just experienced a life-and-death battle.

"Fortunately, I have this ancient book," the old man said. His voice was filled with relief, and his tense nerves finally relaxed a little.

However, before they could recover from their shock, the crystal ball changed again. This time, a mysterious figure appeared in the crystal ball. The figure was blurry, but it exuded a powerful pressure.

"What is this?" The man in black robe widened his eyes, his face full of disbelief.

Zhang Hao struggled to stand up, "No matter what it is, we must deal with it carefully."

The mysterious figure gradually became clearer, and everyone couldn't help but gasp after seeing it clearly...
