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

The metal box was cold to the touch, and Professor Zhang's fingers gently stroked the lid of the box, as if he was stroking the wheel of fate. The box contained the result of his life's research - a serum that could reverse evolution. However, this invention, which was supposed to benefit mankind, has now become a tool for a mysterious organization to control the world.

"Professor, what are you still hesitating about?" The man in black said in a cold tone, with greed flashing in his eyes. "With it, we can control everything!"

Professor Zhang closed his eyes painfully, and the innocent smiling faces of the children emerged in his mind. Conscience and desire fought fiercely in his heart. Finally, he took a deep breath and made a decision.

"No, I can't make any more mistakes!" Professor Zhang suddenly opened his eyes and threw the metal box in his hand towards the big tree where Chu Mengmeng and Xiao Yichen were hiding.

"Who is it?!" The man in black was horrified and immediately drew his gun and pointed it in the direction of the tree.

Chu Mengmeng and Xiao Yichen looked at each other and realized that they had been exposed, so they no longer hid and walked out from behind the tree.

"Professor Zhang, are you okay?" Chu Mengmeng asked with concern.

Professor Zhang looked at the young couple in front of him with a relieved smile on his face: "Kids, you are finally here! Hurry, stop them and don't let them get the serum!"

A fierce battle was about to break out. The man in black led several of his men to launch a fierce attack on Chu Mengmeng and Xiao Yichen. Although Chu Mengmeng and Xiao Yichen were extraordinary, the other side had more people and was well-trained, so they were unable to resist for a while.

At this moment, Professor Zhang suddenly rushed to the man in black, hugged his arm tightly, and shouted, "Go! Don't be stubborn anymore!"

"Get out of here!" The man in black pushed Professor Zhang to the ground with force, then fled the villa with his men without looking back.

Seeing this, Chu Mengmeng and Xiao Yichen hurried forward to help Professor Zhang up and asked with concern: "Are you okay?"

Professor Zhang waved his hand to indicate that he was fine, then pointed to the metal box on the ground and said, "Quick, open it and take a look!"

Chu Mengmeng picked up the metal box and opened it carefully. She saw several test tubes filled with blue liquid in the box, which was the reverse evolution serum developed by Professor Zhang.

"These serums..." Chu Mengmeng frowned slightly, her heart full of doubts.

"These serums are the antidote!" Professor Zhang explained, "The mysterious organization used my research results to develop a virus that can degenerate humans, and these serums are the only antidote!"

"So that's it!" Chu Mengmeng suddenly realized, "No wonder those people wanted to take the child away, they wanted to use the child for experiments!"

"That's right!" Professor Zhang nodded, "Their ultimate goal is to control the whole world!"

Hearing this, Chu Mengmeng and Xiao Yichen were extremely shocked. They didn't expect that there was such a huge conspiracy behind this incident!

"Professor Zhang, don't worry, we will definitely stop them!" Xiao Yichen said in a firm tone.

Professor Zhang nodded with satisfaction, then handed a USB drive to Chu Mengmeng and said, "It contains all my research materials and evidence of the crimes of the mysterious organization. You must hand it over to the police!"

"We will!" Chu Mengmeng took the USB drive solemnly.

"Kids, I'm counting on you!" Professor Zhang looked at Chu Mengmeng and Xiao Yichen, his eyes full of hope.

Chu Mengmeng and Xiao Yichen knew that they had the responsibility of saving the world, so they made a detailed plan and prepared for a decisive battle at the headquarters of the mysterious organization.

The night of the decisive battle is approaching, and the darkness before dawn is shrouding the earth, but Chu Mengmeng and Xiao Yichen believe that the dawn is just ahead!

As night falls, the city falls into silence, with only the whistling cold wind reminding people of the harshness of winter. However, on this seemingly peaceful night, a decisive battle concerning the fate of mankind is about to begin.

The headquarters of the mysterious organization, a heavily guarded steel fortress, stands in the wilderness on the edge of the city. This place was once the nightmare of countless people, and tonight, it will usher in the final judgment.

Chu Mengmeng and Xiao Yichen, dressed in black night clothes, led an elite team and quietly sneaked into this forbidden area. Each of their faces was full of determination. For justice, for children, and for the future of mankind, they embarked on this thorny road without hesitation.

"Remember, our goal is to rescue the children and destroy the virus. Don't fight to the end!" Xiao Yichen whispered, with a hint of solemnity in his deep eyes.

"Understood!" The team members answered in low voices. They were all elites who had undergone special training. Every movement was clean and neat, like cheetahs, moving freely in the darkness.

According to the plan made in advance, they split into two groups. Xiao Yichen led a team to attract the enemy's attention, while Chu Mengmeng led another team to attack the underground laboratory where the children were imprisoned.

The infiltration process was smoother than expected. The mysterious organization did not seem to expect that they would choose to launch an attack tonight, and the internal defense line was full of loopholes. With her extraordinary skills and agile mind, Chu Mengmeng cleverly avoided the layers of guards and quickly found the entrance to the underground laboratory.

"Mengmeng, be careful!" Xiao Yichen's anxious voice came from the communicator. It was obvious that he had exchanged fire with the enemy.

"Don't worry, you should be careful too!" Chu Mengmeng responded in a low voice, then cut off the communication and focused all her attention on the task at hand.

The door of the underground laboratory was closed, with two fully armed guards standing on both sides. Chu Mengmeng took a deep breath, rushed forward, and in a flash, she had knocked the two guards to the ground.

When I pushed open the door, a cold and damp breath hit me in the face. The lights in the laboratory were dim, and there were instruments and equipment flashing strange lights everywhere, which was creepy.

"Dad, Mom!"

At this moment, a childish voice sounded from deep in the laboratory. Chu Mengmeng's heart was shocked. She looked in the direction of the voice and saw a pair of adorable twins, a boy and a girl, locked in a huge glass container. They were her children, Xiao Xiao and Xiao Yao.

"Xiaoxiao, Yaoyao!" Chu Mengmeng rushed forward excitedly and held the children's hands tightly through the glass container.

"Mom, you're finally here. I missed you so much!" Xiao Xiao and Xiao Yao burst into tears of joy when they saw Chu Mengmeng.

"Don't be afraid, kids, mom will take you home now!" Chu Mengmeng held back her tears and comforted the children. At the same time, she quickly glanced around, looking for a way to open the glass container.

"Want to save them? Not that easy!"

A cold voice sounded at the door of the laboratory. Chu Mengmeng turned around suddenly and saw a mysterious man wearing a black cloak and a mask slowly walking in. In his hand was a dagger flashing with cold light. It was the leader of the mysterious organization - Black Demon! The appearance of Black Demon made the already tense atmosphere drop to the freezing point in an instant. Chu Mengmeng's heart trembled. She knew that the real decisive battle was coming.

"What do you want?" Chu Mengmeng protected the children behind her and stared at the black demon vigilantly.

"Hand over the antidote to the virus, and I can consider releasing these two brats." The Black Devil's voice was hoarse and low, like a call from hell.

"Don't even think about it!" Chu Mengmeng flatly refused. The antidote to the virus was related to the safety of all mankind, and she would never compromise.

"If you don't accept my toast, you will be punished!" A trace of cruelty flashed in the black devil's eyes. He swung the dagger in his hand, and a cold light came straight towards Chu Mengmeng.

Chu Mengmeng was prepared and dodged the attack by leaning sideways. At the same time, she flipped her wrist and several silver needles flew out, aiming directly at the Black Demon's vital points. The Black Demon snorted coldly and dodged like a ghost, and all the silver needles missed.

"Little tricks!"

Before the Black Demon finished speaking, he had already rushed forward and fought with Chu Mengmeng. Although Chu Mengmeng had special skills, she was a new mother after all, and she was exhausted and gradually fell behind.

"Meng Meng, let me help you!"

At this moment, a roar was heard, and Xiao Yichen arrived with his men and joined the battle. Although Xiao Yichen did not have the high martial arts skills of Chu Mengmeng, he was smart and brave, and joined forces with Chu Mengmeng to fight the black demon on equal terms.

The sound of fighting in the laboratory alarmed the guards outside, and more and more members of the mysterious organization poured into the laboratory and surrounded Chu Mengmeng and others.

"Haha, you can't escape today!" The black devil laughed wildly, his eyes full of joy of victory.

"Really?" Chu Mengmeng curled up the corner of her mouth into a sneer. She pressed the button that had been prepared in her hand. With a loud "bang", the wall of the laboratory collapsed. The dazzling sunlight shone in from outside, illuminating the entire laboratory.

It turned out that before sneaking into the laboratory, Chu Mengmeng had already made arrangements. She contacted the police and informed them of the specific location of the laboratory. The police had already been lying in ambush nearby, just waiting for her signal.

The sudden change caught Black Demon and his men off guard. Before they could react, the police rushed in and surrounded them.

"Don't move, put down your weapons, and surrender immediately!"

Facing the black muzzle of the gun, Black Demon's men threw away their weapons and surrendered. Black Demon saw that the situation was hopeless and struggled madly, trying to make a final resistance, but Xiao Yichen kicked the dagger out of his hand and he was pinned to the ground by the police.

"It's over, Black Demon!" Chu Mengmeng walked in front of the Black Demon, her eyes filled with victory.

The Black Devil glared at Chu Mengmeng fiercely and said with gritted teeth: "Don't be complacent, this game is not over yet!"

After saying that, the Black Demon suddenly laughed out loud towards the sky. The laughter was shrill and crazy, echoing in the empty laboratory, making people shudder.

Chu Mengmeng's heart trembled, and an ominous premonition came to her mind. What other tricks did the Black Demon have? Was this battle really over?

 Chapter 210 Dawn Arrives

Black Demon's laughter echoed in the empty laboratory, with a bit of sadness and determination. Chu Mengmeng's uneasiness became stronger and stronger. She intuitively felt that Black Demon's words were not alarmist.

At this time, Dr. Li, who had been silent all the time, suddenly spoke up. His voice trembled with a hint of fear: "It's too late. Everything is too late..."

Dr. Li's words were like a bomb, exploding in everyone's ears. Chu Mengmeng turned her head and looked at him, "What do you mean by that?"

Dr. Li slumped on the ground with a hollow and desperate look in his eyes. "The virus... the virus has already spread... When you broke into the laboratory, I had already started the final procedure... Now, the virus is already in the air all over the world..."

"what?!"

Chu Mengmeng and Xiao Yichen's faces changed drastically. They never thought that the Black Demon could be so cruel and cruel that he would use such a self-destructive method to achieve his goal.

"Hahaha, do you think you can stop me like this? Too naive! This world will be mine sooner or later!" The Black Demon laughed arrogantly, as if he had already seen the scene of himself ruling the world.

However, his laughter soon stopped because he saw that there was no panic or fear on Chu Mengmeng's face, but instead a meaningful smile.

"What are you laughing at?!" A bad premonition suddenly arose in the Black Demon's heart.

"I laugh at you. You are too clever and have calculated everything, but it has cost you your life." Chu Mengmeng spoke slowly. Her tone was calm, but it carried a majesty that could not be ignored.

"What do you mean?" The Black Demon felt increasingly uneasy.

Chu Mengmeng did not answer him, but turned to look at Dr. Li, "Dr. Li, you said before that you developed an antidote for the virus, right?"

Dr. Li was stunned for a moment, then he seemed to remember something, and a glimmer of hope rekindled in his eyes, "Yes! That's right! I have developed an antidote! As long as the antidote is spread, the spread of the virus can be stopped!"

"Very good." Chu Mengmeng nodded, "I believe you, Dr. Li."

As she spoke, Chu Mengmeng took out a delicate little bottle from her pocket and handed it to Dr. Li, "This contains a more powerful antidote. I have prepared it in advance."

Dr. Li took the bottle, his hands shaking with excitement, "How...how did you know?"

Chu Mengmeng smiled slightly, "I guessed that you would hold back, so I made preparations in advance."

It turns out that when Chu Mengmeng discovered the virus, she realized that things were not that simple. She secretly observed Dr. Li and found that although he was coerced by the black magic, he still retained a trace of conscience deep in his heart. So, she sneaked into Dr. Li's laboratory, found the antidote formula he had hidden, and prepared a stronger antidote in advance.

"Impossible! This is impossible!" The Black Demon completely collapsed. He never thought that everything he had carefully planned was seen through by Chu Mengmeng.

Chu Mengmeng ignored the Black Demon's hysteria. She arranged for people to escort Dr. Li out and asked him to spread the antidote as soon as possible.

Looking at Dr. Li's receding back, Chu Mengmeng and Xiao Yichen smiled at each other, their eyes filled with hope.

The sunlight shone on them through the holes in the laboratory, as if heralding the coming of light.

**However, is this victory really the final victory? Has the Dark Devil really been defeated? Can Chu Mengmeng and Xiao Yichen's family really live a peaceful life from now on? **
