Me? I was transported into a book? And I became a vicious villain?

The golden dragon, with its might of destroying the heavens and the earth, rushed straight towards the staff in the mysterious woman's hand. Feeling this powerful force, the mysterious woman's face changed slightly, she quickly retreated, and at the same time waved her staff, black mist surged out, forming a huge shield, trying to resist the attack of the golden dragon.

"boom!"

A loud bang shook the sky, and the golden dragon collided with the black shield, bursting into dazzling light. A powerful shock wave swept across, uprooting the surrounding trees and collapsing houses in an instant.

Chu Mengmeng and Xiao Yichen took advantage of this opportunity to quickly approach the mysterious woman. The weapons in their hands flashed dazzling light, and they attacked her vital points with unstoppable force.

However, the mysterious woman was powerful after all. She reacted quickly, and the black mist condensed into a sharp sword in her hand, which collided with the attacks of Chu Mengmeng and Xiao Yichen, making a harsh metal collision sound.

For a moment, the magical lights outside the castle intertwined, explosions sounded one after another, the figures of the three people kept flashing in it, every collision seemed to shake the earth, and everything around them trembled under this powerful force.

At this moment, a clear voice sounded at the edge of the battlefield: "Stop!"

Hearing this voice, Chu Mengmeng and Xiao Yichen were both slightly stunned. They turned their heads and saw a woman in a white dress standing not far away. She had an anxious look on her face and was staring at them closely.

"Who are you?" Xiao Yichen asked vigilantly, his hand still tightly holding the weapon without any relaxation.

"I'm here to help you." said the white woman, raising the staff in her hand. A soft white light shot out from the top of the staff and fell on Chu Mengmeng and Xiao Yichen. Suddenly, they felt a warm power surging into their bodies, and the physical strength and magic power that had been consumed quickly recovered.

"You..." Chu Mengmeng looked at the woman in white in surprise, not understanding why she wanted to help her.

"Now is not the time to explain, let's join forces to deal with him first!" The white woman did not say much. She waved her staff, and white rays of light shot out and attacked the mysterious woman.

The mysterious woman obviously did not expect a helper to suddenly appear. She was caught off guard and hit by the white light, and her body involuntarily took a few steps back.

"Let's attack together!" Seeing this, Xiao Yichen shouted and attacked the mysterious woman together with Chu Mengmeng.

The three-on-one situation instantly turned the originally stalemate battle around. Although the mysterious woman was powerful, she gradually felt exhausted facing the joint attack of three people. The magic power in her body was quickly consumed and her movements began to become slow.

"I can't go on like this!" The mysterious woman thought to herself. She must get out of her current predicament as soon as possible, otherwise the consequences will be disastrous.

Thinking of this, she gritted her teeth, a trace of determination flashed in her eyes, and she quickly formed seals with her hands and muttered something. The black mist around her began to surge violently, and a powerful force was quickly gathering...

"Oh no, he's going to use his ultimate move!" Chu Mengmeng felt this powerful force and her face suddenly changed.

"Don't panic, we also have a way to deal with him!" Xiao Yichen said, holding Chu Mengmeng's hand. A powerful force surged out of his body and merged with Chu Mengmeng's power to form a huge energy vortex...

The energy vortex emitted dazzling light, illuminating the entire night sky. The figures of Chu Mengmeng and Xiao Yichen were looming in the light. They looked at each other, their eyes full of determination and trust.

"Are you ready?" Xiao Yichen's voice sounded in Chu Mengmeng's ears, steady and powerful.

"Yes!" Chu Mengmeng nodded heavily, holding tightly in her hand a long sword emitting golden light.

The two men raised their weapons at the same time, and the power of the energy vortex gathered on the weapons, forming a huge pillar of light, which rushed straight towards the mysterious woman with the power to destroy the world.

The mysterious woman obviously did not expect that Chu Mengmeng and Xiao Yichen could mobilize such powerful force. Her face changed drastically, and it was too late for her to dodge. She could only watch the beam of light coming towards her.

With a loud bang, the beam of light hit the mysterious woman hard. A powerful shock wave swept across, and everything around her was razed to the ground. The black mist was also completely dispelled by this powerful force.

Chu Mengmeng and Xiao Yichen landed slowly, looking at the mess in front of them, their hearts filled with the joy of victory. However, they did not let down their guard, because they knew that things were not over yet.

Sure enough, at this moment, a cold voice came from the ruins: "Do you think you can defeat me like this? Too naive!"

Immediately afterwards, a black figure slowly rose from the ruins, thick black mist emanating from his body. His pair of blood-red eyes stared at Chu Mengmeng and Xiao Yichen, full of resentment and murderous intent.

"You ants, you dare to hurt me. I will make you pay a heavy price!"

The black figure roared and raised his hands high. The surrounding dark elements rushed towards him madly, forming a huge black vortex that seemed to swallow up the entire world.

"This is... a dark forbidden technique!" The white woman turned pale and exclaimed, "He wants to drag us all into endless darkness!"

Chu Mengmeng and Xiao Yichen also felt this powerful force, and their hearts sank instantly.

"Don't be afraid, Mengmeng, I'm here!" Xiao Yichen held Chu Mengmeng's hand tightly and said in a deep voice.

"Yes!" Chu Mengmeng nodded, looking firmly at the black fog in front of her, praying silently in her heart...

The black vortex grew larger and larger, and the power of darkness seemed endless, enveloping Chu Mengmeng and Xiao Yichen. Xiao Yichen protected Chu Mengmeng behind him, and the black mist entangled them like a maggot, trying to devour them...

The thick darkness was like a huge black curtain, trying to swallow Chu Mengmeng and Xiao Yichen. Xiao Yichen protected Chu Mengmeng behind him, wielding the long sword in his hand, and the golden sword energy cut through the darkness, leaving behind dazzling rays of light. The black mist entangled like a maggot on the tarsal bone, but dissipated the moment it came into contact with the golden light.

"Mengmeng, don't be afraid, I'm here." Xiao Yichen's voice was particularly clear in the darkness, like a flash of lightning, illuminating Chu Mengmeng's heart.

"Yes!" Chu Mengmeng held Xiao Yichen's hand tightly, feeling the warmth of his palm, and a strong power surged in her heart. She was no longer the delicate young lady, she was a warrior fighting side by side with Xiao Yichen!

The two stood back to back, resisting the erosion of darkness. Although their strength was weak, their love and faith were indestructible. They believed that light would eventually defeat darkness and hope would never die.

At this moment, a white figure descended from the sky and landed in front of them. It was the mysterious woman!

"You did a great job," the mysterious woman looked at them with admiration in her eyes, "I have found his weakness. It is in his chest. There is a dark heart there. It is the source of the dark power."

"But his dark power is too strong, we can't get close to him at all." Chu Mengmeng said anxiously.

"I will try my best to restrain him, and you take the opportunity to attack his weaknesses!" said the mysterious woman, quickly forming seals with her hands. A beam of white light shot up into the sky, tearing a hole in the black vortex.

"It's now!"

Xiao Yichen pulled Chu Mengmeng up, and the two of them turned into two streams of light and rushed into the black vortex. The black mist surged wildly, trying to stop them from moving forward, but they were fearless, with only the beating heart of darkness in their eyes.

Finally, they came to the mysterious enemy. He was tall and mighty, exuding a suffocating dark aura. He looked down at them with a scornful smile on his face.

"Unbelievable!"

He slowly raised his hand, and a black ball of energy gathered in his palm, as if to destroy them completely.

"Mengmeng, are you ready?" Xiao Yichen held Chu Mengmeng's hand tightly with a firm look in his eyes.

"Yeah!" Chu Mengmeng nodded, with a determined light flashing in her eyes.

The two men raised their weapons at the same time, and the golden light and the white light intertwined to form a dazzling beam of light, heading straight for the chest of the mysterious enemy...

"what--"

A shrill scream resounded through the sky, and the body of the mysterious enemy trembled violently. Black mist gushed out of his body frantically, as if to drag the whole world into an endless abyss. He looked down at his chest in disbelief. There was a huge hole there, and the Heart of Darkness had disappeared...

"Do not--"

With a final unwilling roar, the mysterious enemy's body turned into black powder and dissipated into the air. The black vortex also disappeared, and the sky became clear again. The sun shone on them, warm and comfortable.

Chu Mengmeng and Xiao Yichen smiled at each other. They knew that they had won. They finally defeated the darkness and protected their home.

The mysterious woman walked up to them with a pleased smile on her face, "Congratulations, you succeeded."

"All this is thanks to your help." Chu Mengmeng said gratefully.

"You're welcome," the mysterious woman shook her head, "This is my responsibility and my destiny. Now, my mission is complete, and it's time to leave."

"Are you leaving?" Chu Mengmeng was a little reluctant.

"All good things must come to an end," the mysterious woman smiled, "I believe we will meet again."

After saying this, her figure gradually became transparent and finally disappeared into the air.

Chu Mengmeng and Xiao Yichen watched her leave, their hearts filled with gratitude and admiration.

At this moment, they suddenly felt a powerful energy wave coming from the direction of the castle...

"Not good," Xiao Yichen's face changed, "The castle's shield has disappeared, let's go check it out!"

The two turned around without hesitation and ran towards the castle...

Inside the castle, the wind was blowing. The once magnificent hall was now in a mess. Black mist was swirling in the air, making creepy sounds. Chu Mengmeng and Xiao Yichen moved forward cautiously, holding weapons in hand, taking every step very carefully.

"Be careful!" Xiao Yichen grabbed Chu Mengmeng and dodged a sudden black lightning.

"This dark force is stronger than before. We must find the source as soon as possible!" Chu Mengmeng's face was solemn. A ball of white light condensed in her hand, dispelling the darkness around her.

They followed the darkest spot all the way up, and finally came to the secret room on the top floor of the castle. The door of the secret room was engraved with strange runes, exuding a disturbing atmosphere.

"This is it." Xiao Yichen clenched the sword in his hand, and a powerful sword energy gushed out, blasting open the door of the secret room.

In the center of the secret room, a huge black crystal ball was suspended in the air, emitting a frightening dark energy. Black mist continued to pour out of the crystal ball, like a bottomless pit, greedily devouring all the light around it.

"This is the source of dark magic!" Chu Mengmeng recognized the crystal ball at a glance and felt an uneasy premonition in her heart.

At this moment, the crystal ball suddenly trembled violently, and the black mist rolled even more violently, as if something terrible was about to break out of its shell.

"Oh no! It's going to get out of control!" Xiao Yichen's face changed, and he made a quick decision. He swung the sword in his hand, and a golden sword energy went straight to the crystal ball.

With a loud bang, the golden sword energy hit the crystal ball, bursting out with dazzling light. The black mist surged frantically, trying to resist the attack of the sword energy, but was eventually swallowed up by the golden light.

The crystal ball let out a shrill wail, and countless cracks appeared on its surface. The black mist gradually dissipated, revealing the true face of the crystal ball—a heart as black as ink, beating weakly.

"This is..." Chu Mengmeng widened her eyes and looked at the scene in front of her in disbelief.

"Heart of Darkness..." Xiao Yichen's face was solemn, "So, this is the real source of dark magic."

"We must destroy it completely!" Chu Mengmeng said without hesitation. A ball of white light condensed in her hand and was about to attack the Heart of Darkness.

"Wait!" Xiao Yichen suddenly grabbed her, "This Heart of Darkness is connected to the entire dark world. If we destroy it rashly, it may cause unpredictable disasters!"

At this moment, the door of the secret room was pushed open and a white figure walked in.

"You guys did a great job."
