"Who are you?" Hu Yulun asked warily, gripping his sword hilt tightly. His body was slightly forward, and his eyes, sharp as a hawk's, were fixed on the Dark Wizard.
The Dark Wizard sneered, "I am the master of this place. You won't be leaving here alive." His voice seemed to come from the abyss, filled with endless coldness. The Dark Wizard was cloaked in black, his face hidden in the shadows of his hood, revealing only a pair of eyes that glimmered with an eerie light.
Isabella cried out, "Stop your theatrics! Today is your end!" She raised her longsword, its blade shimmering with magical light. Her beautiful face was even more captivating with anger.
The Dark Wizard let out a sinister laugh. "Just you two? How utterly foolish!" He waved his Magic Wand, and a cloud of black smoke instantly surged towards the three of them.
"Watch out!" Merlin shouted, quickly raising his staff. He muttered an incantation, and a beam of light shot out from the staff's tip, colliding with the black smoke and producing a "hissing" sound.
Taking advantage of this moment, Hu Yulun charged at the Dark Wizard like an arrow released from a bow, his sword thrusting straight forward. The Dark Wizard sidestepped, easily evading Hu Yulun's attack. At the same time, with a wave of his Magic Wand, a powerful force knocked Hu Yulun back a few steps.
"Damn it!" Hu Yulun steadied himself and charged forward again, his sword moving with lightning speed.
Isabella was not to be outdone. She cast various spells, fire, frost, and lightning intertwining as they attacked the Dark Wizard. The Dark Wizard was forced to divert his attention to deal with Isabella's attacks, and for a moment, he seemed somewhat flustered.
"Hahaha, let's see how much longer you can last!" Isabella shouted, her eyes filled with confidence.
The Dark Wizard snorted coldly, "Don't be so smug, little girl!" Suddenly, he began chanting, and the surrounding dark energy quickly gathered at the tip of his Magic Wand, forming a massive black Energy Ball.
"No, get out of the way!" Merlin exclaimed.
But it was too late. The Dark Wizard hurled the Energy Ball towards them. Hu Yulun didn't hesitate and stood in front of Isabella and Merlin, attempting to block the powerful force with his sword.
"BOOM!" With a deafening explosion, Hu Yulun was knocked back by the immense impact, slamming into the wall before falling to the ground.
"Hu Yulun!" Isabella cried out, rushing towards him with worry in her eyes.
"I'm fine, don't worry about me, keep fighting!" Hu Yulun gritted his teeth and got up from the ground, a trickle of blood at the corner of his mouth.
Merlin, at this moment, also cast a powerful Protective Magic, enveloping the three of them within its protection.
"Children, we must work together if we want to defeat him!" Merlin said.
Isabella nodded, raising her longsword again and charging towards the Dark Wizard with Hu Yulun.
The Dark Wizard's face showed a hint of panic at this, but he quickly regained his composure. He continuously cast various dark magic spells, trying to stop their attack.
Hu Yulun's sword clashed repeatedly with the Dark Wizard's Magic Wand, sending sparks flying. Isabella's magic also kept exploding around the Dark Wizard.
"You can't defeat me!" the Dark Wizard shouted madly.
"As long as we don't give up, we will definitely beat you!" Hu Yulun replied.
During the fierce battle, Hu Yulun found that the Dark Wizard's left side defense was relatively weak.
"Isabella, attack his left side!" Hu Yulun shouted.
Isabella understood instantly and focused her magic, attacking the Dark Wizard's left side. The Dark Wizard scrambled to defend himself, and Hu Yulun seized the opportunity, thrusting his sword towards the Dark Wizard's chest.
The Dark Wizard let out a scream and collapsed to the ground.
"We finally beat him!" Isabella exclaimed excitedly.
However, just when they thought they had won, the Dark Wizard suddenly stood up again.
"Do you think you can kill me like that? How naive!" The Dark Wizard's voice became even more sinister and terrifying.
He began to gather dark energy once more, and the entire Castle began to tremble.
"This is bad, he's making a final stand!" Merlin said.
Hu Yulun gritted his teeth, "No matter what, we can't let him succeed!"
They joined forces again, engaging in a final, desperate struggle with the Dark Wizard.
Isabella's magic glowed ever brighter, Hu Yulun's sword swung with increased ferocity, and Merlin's Magic Wand continuously unleashed powerful forces.
The Dark Wizard gradually lost ground, his dark power beginning to dissipate.
"No, this can't be!" the Dark Wizard cried out in despair.
With the final flash of light, the Dark Wizard vanished completely, and the Castle returned to peace.
"We did it!" Isabella exclaimed, embracing Hu Yulun and Merlin.
Hu Yulun gave a tired smile. "Yes, we did."
Merlin looked at them, his eyes filled with satisfaction. "My children, you did well."
They rested for a while and began exploring the Castle. An air of antiquity permeated the Castle; ancient portraits hung on the walls, and the ground was covered in thick dust.
"This feels strange," Isabella said.
Hu Yulun cautiously pushed open a door, revealing a room filled with all sorts of precious treasures.
"Wow, so many treasures!" Isabella exclaimed.
Merlin stepped forward, carefully examining the treasures: "These might be helpful to us."
Just as they were about to select some treasures to take with them, they suddenly heard a low roar.
"What's that?" Hu Yulun gripped his sword warily.
They followed the direction of the sound and arrived at a huge basement. The basement was dark and damp, giving off a putrid smell.
"Look, what's that?" Isabella pointed ahead.
A huge monster was chained to the wall. Its eyes glowed with red light, and it exhaled a cloud of hot air.
"Is it the Dark Wizard's pet?" Hu Yulun asked.
The monster saw them and struggled violently to break free from its chains.
"Be careful, it's dangerous!" Merlin warned.
Suddenly, the monster exerted its strength, snapping the chains and lunging towards them.
Hu Yulun didn't flinch, meeting the monster head-on. His sword slashed across the monster's body, leaving wounds.
The monster roared in anger and turned to attack Isabella. Isabella dodged nimbly while casting magic to attack the monster's eyes.
Merlin, meanwhile, was looking for the monster's weak point.
"I found it, attack its belly!" Merlin shouted.
Hu Yulun and Isabella, upon hearing this, focused their attacks on the monster's belly. The monster fell to the ground in agony, and after struggling for a few moments, it stopped moving.
"Phew, finally dealt with it," Hu Yulun sighed in relief.
They continued to explore the castle and discovered an ancient Magic Book.
"This Magic Book might hold important secrets," Merlin said.
They opened the Magic Book, and the words within shimmered with a mysterious light.
"What does it say?" Isabella asked.
Merlin studied the text in the book carefully. "This seems to be a powerful magic spell, but it requires specific conditions to cast."
\n\n
Just then, a noisy commotion came from outside the Castle.
\n\n
"Let's go see what's happening," Hu Yulun said.
\n\n
They went out of the Castle and saw a group of Evil Soldiers approaching them.
\n\n
"They're the Dark Wizard's henchmen!" Isabella exclaimed.
\n\n
"Prepare for battle!" Hu Yulun shouted.
\n\n
The soldiers swarmed forward, engaging them in a fierce fight.
\n\n
Hu Yulun's sword danced through the crowd, Isabella's magic continuously knocked down enemies, and Merlin's Magic Wand unleashed a powerful force, pushing the enemies back.
"You evil lot, you won't stop us!" Hu Yulun shouted.
After a hard-fought battle, they finally defeated all the enemies.
"I'm so tired," Isabella said, sitting on the ground and gasping for breath.
Hu Yulun looked at the corpses scattered on the ground. "But we've won again."
Merlin said, "We can't stay here too long; more challenges await us."
They continued on, carrying the Magic Book. Along the way, they encountered various difficulties and dangers, but they overcame them all with courage and wisdom.
Finally, they arrived at a mysterious Valley. The valley was shrouded in thick fog, making it impossible to see the road ahead.
"Be careful, there might be traps here," Hu Yulun warned.
They cautiously entered the valley, and suddenly heard a melodious flute sound.
"What is that sound?" Isabella asked.
Merlin frowned. "This flute sound is unusual. It might be some kind of magical summoning."
As the flute music grew clearer, a mysterious figure appeared before them.
