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

Two figures passed by like the wind, and Su Mubai and Lin Wan'er arrived in time with reinforcements. They were well-trained, and with the flash of swords, they forced the shadows back to the corner of the secret room, and finally disappeared.

"Mengmeng, are you okay?" Lin Wan'er anxiously checked Chu Mengmeng's injuries, and only breathed a sigh of relief when she saw that she was safe and sound.

"I'm fine," Chu Mengmeng shook her head, but her eyes were fixed on the deep and unfathomable cave. "Those shadows came out from there. We must find out what secrets are hidden in there."

Xiao Yichen nodded in agreement: "Yes, only by finding the source can the problem be completely solved."

“But…” Lin Wan’er looked embarrassed. “The cave is full of dangers. We know nothing about what’s inside. It’s too dangerous to rush in.”

"We can't just sit there and wait for death," Su Mubai said solemnly, "The power of the black shadows is growing stronger and stronger. If we can't stop them in time, the whole city will be in danger."

After a brief silence, everyone unanimously decided to go deeper into the cave and explore the secrets within.

The cave was cold and damp, and filled with a disgusting stench. Everyone moved forward cautiously, and the sound of gravel rolling under their feet could be heard from time to time, echoing in the silent cave, adding a bit of weirdness.

"careful!"

Xiao Yichen, who was walking in the front, suddenly stopped and swung the sword in his hand to cut off a vine hanging from his head. The vine fell to the ground, twisted a few times, and then quickly withered and rotted, turning into a pool of black water.

"These vines are poisonous!" Su Mubai warned.

Everyone became more cautious, and after overcoming all obstacles along the way, they finally reached the depths of the cave.

What appeared before their eyes was a huge underground space. The surrounding walls were inlaid with unknown glowing minerals, illuminating the entire space.

"What is this place?" Lin Wan'er asked in surprise.

"It looks like a laboratory." Su Mubai walked forward and carefully observed the symbols and patterns on the wall.

In the center of the laboratory, there is a huge metal device, surrounded by various complex pipes and instruments, exuding a cold and mysterious atmosphere.

"These symbols..." Chu Mengmeng walked to the device and carefully identified the words on it, "It seems to be an ancient language."

"Can you interpret it?" Xiao Yichen asked.

Chu Mengmeng shook her head, but she did not give up. Instead, she began to carefully observe the environment around the device, hoping to find some clues.

Suddenly, her eyes fell on a stone tablet next to the device. There were some strange symbols engraved on the stone tablet, which were very similar to the symbols on the device.

"Perhaps, this stone tablet is the key to solving the mystery!" A glimmer of hope surged in Chu Mengmeng's heart. She reached out her hand and gently stroked the symbols on the stone tablet. Suddenly, some images flashed through her mind...

"...An ancient prophecy says that darkness is coming and swallowing up light...Only by finding the sealed place and using the power of the holy object can we dispel the evil..."

The picture was intermittent, but Chu Mengmeng captured the key information from it. She opened her eyes suddenly, her eyes flashing with excitement.

"I know! I know how to crack this device!"

When everyone heard this, they all looked at her in surprise.

Chu Mengmeng pointed to the symbols on the stone tablet and explained, "These symbols are an ancient language that records the origin and usage of this device. According to the records above, this device is a seal used to suppress an evil magical force. And those black shadows are controlled by this magical force."

"Then how do we lift the seal?" Lin Wan'er asked anxiously.

"The seal requires a specific password to open, and the password is hidden on this stone tablet." Chu Mengmeng pointed to a group of symbols on the stone tablet and said, "This group of symbols represents the trajectory of the stars. As long as they are arranged in the correct order, the seal can be unlocked."

Everyone suddenly realized what was going on and gathered around, carefully studying the symbols on the stone tablet.

"But the orbits of the stars are so complicated, how can we determine the correct order?" Su Mubai frowned.

"Don't worry, I know the answer." Chu Mengmeng smiled confidently. She had a strong interest in astronomy and geography since she was a child, and she knew the movement paths of the stars like the back of her hand.

She stretched out her slender hands and slid them gently across the stone tablet, arranging the symbols representing the stars in a specific order.

As the last symbol fell into place, the stone tablet suddenly emitted a dazzling light, and the entire underground space began to vibrate violently.

"Success!" Everyone was ecstatic upon seeing this.

The device slowly opened, revealing a black metal box. Chu Mengmeng carefully opened the box, and inside was a crystal ball.

The crystal ball emitted a soft light. Chu Mengmeng put her hand on it. A powerful energy instantly surged into her body, and a piece of information emerged in her mind.

"I see. The source of the black shadow is..."

Chu Mengmeng's face changed, she put away the crystal ball, and said in a deep voice: "We must leave here immediately!"

Everyone did not dare to delay and followed Chu Mengmeng to quickly evacuate the underground space.

Shortly after they left, the entire underground space collapsed, burying all the secrets deep underground.

"Mengmeng, are you okay?" Xiao Yichen asked with concern.

Chu Mengmeng shook her head, her face was extremely solemn: "I'm fine, it's just..."

She took a deep breath and said slowly: "I learned from the crystal ball that the source of the shadow is located in a place called 'Death Swamp' outside the city. It is shrouded in miasma all year round and is full of dangers. It is not easy to find the source of magic and destroy it..."

"Death Swamp..." Xiao Yichen repeated the name, frowning, and a sense of uneasiness spread in his heart. He knew that what was waiting for them would be a more brutal battle.

"There is no time to lose, we must set off as soon as possible." Su Mubai said in a deep voice, with a determined light flashing in his eyes.

In order to find the source of magic, Chu Mengmeng and others decided to take the risk to cross this dangerous death swamp. They were ready to go, and everyone's face was full of solemnity.

As soon as I stepped into the swamp, a rotten smell hit me in the face, making me sick. Under my feet was a muddy swamp, and I would be deeply trapped in it if I was not careful. The thick miasma filled the air, covering the sky and the sun, and the visibility was extremely low. I could only vaguely see the scenery a few meters away.

"Watch your step!" Lin Wan'er reminded. She carefully avoided the smelly puddles on the ground, holding a sharp dagger tightly in her hand, and was always alert to the movements around her.

They trudged forward, each step was extremely difficult. In the swamp, there were all kinds of strange monsters lurking, hiding in the mud, waiting for an opportunity to move, ready to launch a fatal attack on the invaders at any time.

"Ah!" A scream broke through the silence of the swamp. A city guardian unfortunately stepped on a trap and fell into a huge animal trap hidden in the mud. The sharp steel teeth closed instantly, and blood dyed the turbid muddy water red.

"Go save him!" Xiao Yichen shouted and rushed forward first. He and Su Mubai worked together to pry open the trap and rescued the injured companion.

However, the danger was far from over. Just as they were trying to save their companions, a group of swamp monitors with sharp fangs jumped out of the muddy water, opened their bloody mouths, and launched a fierce attack on them.

"Be careful!" Chu Mengmeng shouted, and a long sword flashing with cold light suddenly appeared in her hand, with a faint golden light flowing on the sword. She was agile and her sword skills were sharp, like a dancing butterfly, moving freely among the giant lizards, and each swing of the sword could accurately hit the vital points of the giant lizards.

Xiao Yichen and others also took out their weapons and fought a desperate battle with the giant lizard. For a moment, the swamp was filled with shouts of killing, blood splattered, and a battle between man and beast began.

After a fierce battle, the city guardians finally repelled the giant lizards, but they also paid a heavy price. Several guardians were seriously injured and their physical strength was exhausted. The situation was not optimistic.

"We can't go on like this, we must find the source of the magic as soon as possible!" Lin Wan'er said anxiously.

"I know, but now we are lost and don't know where to go." Su Mubai's face was solemn.

At this moment, a cold voice suddenly sounded in their ears: "Are you looking for me?"

Everyone was startled and looked in the direction of the sound. They saw a mysterious figure in a black cloak slowly walking out of the miasma. He was wearing a silver mask, so his true face could not be seen, but from the powerful aura emanating from him, they could tell that this man was no ordinary person.

"Who are you?" Xiao Yichen asked vigilantly.

"It doesn't matter who I am. What matters is that you all have to die here today!" the shadow leader said coldly, with a bloodthirsty light flashing in his eyes.

An unprecedented crisis is approaching the city guardians...
