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

"boom!"

The noise was deafening, gravel flew everywhere, smoke and dust filled the air, and Chu Mengmeng disappeared in the chaos.

"Meng Meng!" Su Mubai exclaimed and was about to rush into the smoke, but was stopped by Xiao Yichen.

"Don't be impulsive, it's too dangerous to go in now!" Xiao Yichen said calmly, his eyes fixed on the rolling smoke. He could feel that Chu Mengmeng's breath was still there, but it was covered by a powerful force.

The smoke and dust gradually dissipated, revealing the scene inside. Chu Mengmeng was seen standing in front of the armored giant lizard. Her small figure looked particularly thin, but her aura was not weak at all.

She was seen holding a giant sword made of light in both hands. The sword was flashing with dazzling light, illuminating her resolute face.

"Take my sword!" Chu Mengmeng shouted, and the giant sword slashed down fiercely. A huge blade of light cut through the air and slashed towards the armored giant lizard with unstoppable force.

"Roar!"

The armored giant lizard roared, crossed its thick forelimbs in front of its body, and took the blow head-on.

There was another loud noise, and the light blade and scales collided, causing a violent energy fluctuation. The huge body of the armored giant lizard was shaken back a few steps, and Chu Mengmeng also staggered back a few steps due to the huge recoil force.

"What a powerful force!" Xiao Yichen was secretly shocked. Chu Mengmeng's strength seemed to have increased again. The power of this attack even exceeded that of some fourth-level psychics.

"Mengmeng, be careful!" Lin Wan'er reminded from the side. She could feel that the armored giant lizard was not seriously hurt, but its ferocity was aroused instead.

Sure enough, the armored giant lizard roared, opened its bloody mouth, and a black beam of energy shot out from its mouth, straight at Chu Mengmeng.

Chu Mengmeng was prepared and dodged the attack. The black energy beam hit the mountain wall, instantly creating a huge hole.

"Everyone, come together!" Seeing this, Xiao Yichen knew that he could not delay any longer and gave the order immediately.

As soon as he finished speaking, he, Su Mubai and Lin Wan'er attacked at the same time, and various supernatural attacks bombarded the armored giant lizard one after another.

The armored giant lizard was beaten back by the four people's attacks, and many wounds appeared on its body. However, just when everyone thought victory was in sight, a more powerful aura came from the depths of the cave.

"Roar--"

Accompanied by a deafening roar, a huge black shadow slowly walked out of the darkness.

It was a giant beast that was several times larger than the armored giant lizard, covered in black scales and exuding a suffocating pressure.

"The leader of the dark creatures!" Xiao Yichen's pupils suddenly shrank and an ominous premonition arose in his heart.

This battle is far from over, and has become even more dangerous...

"Be careful!" Before Xiao Yichen finished speaking, the dark creature leader had already swung its huge claws and slapped Chu Mengmeng fiercely. Chu Mengmeng was unable to dodge and was swept by the strong wind brought by the huge claws. Her petite body flew out like a kite with a broken string, and a mouthful of blood sprayed in the air.

"Meng Meng!" Xiao Yichen's eyes were bloodshot, and he rushed towards Chu Mengmeng regardless of everything. His spiritual power surged, turning into invisible barriers, blocking the subsequent attacks of the dark creature leader. However, in order to protect Chu Mengmeng, Xiao Yichen had to distract himself, which made his originally impeccable defense appear flawed.

The dark creature leader keenly caught this opportunity, it let out a deafening roar, and a black energy beam spurted out of its mouth, hitting Xiao Yichen's heart. At the critical moment, Xiao Yichen only had time to protect Chu Mengmeng behind him, but he himself could not completely avoid the attack.

"Puff!" The black energy beam penetrated Xiao Yichen's shoulder, leaving a bloody mess. Xiao Yichen groaned in pain, but he gritted his teeth and persisted without falling down.

"Xiao Yichen!" Chu Mengmeng was filled with guilt and worry when she saw Xiao Yichen injured in order to protect her. She struggled to stand up, but because of her severe injuries, she fell to the ground powerlessly.

"Don't worry, I'm fine." Xiao Yichen endured the severe pain and gave Chu Mengmeng a comforting smile. However, his face was frighteningly pale, and the blood at the corner of his mouth was even more shocking.

"Damn you, try this!" Just as the dark creature leader was about to deal a fatal blow to Xiao Yichen, Su Mubai and Lin Wan'er finally arrived. When they saw the scene in front of them, they were immediately furious and launched an attack without hesitation.

Su Mubai had a strange-looking energy gun in his hand, with a dazzling light flashing from the muzzle. He pulled the trigger, and a beam of energy as thick as a bowl whizzed out, fiercely hitting the dark creature leader's chest.

At the same time, Lin Wan'er also waved the long whip in her hand. The whip was wrapped with raging flames and turned into a fire dragon, sweeping towards the leader of the dark creatures.

"Roar!" The dark creature leader was hit by these two attacks and roared in pain. Its huge body stumbled back, leaving black marks on its chest and body.

"What... weapon is this?" Xiao Yichen looked at the energy gun in Su Mubai's hand in surprise. He had never seen such a powerful weapon.

"This is our latest energy weapon, specially designed to deal with these dark creatures." Su Mubai explained, "Although it is still in the experimental stage, its power is already considerable."

The leader of the dark creatures realized that the opponent in front of him was not easy to deal with. He looked at everyone with resentment, then turned and fled into the depths of the cave.

"Want to run? Not that easy!" Su Mubai wanted to chase him but was stopped by Xiao Yichen.

"Don't chase after a desperate enemy. It's already injured and won't pose a threat anymore." Xiao Yichen said calmly, "Our most important thing now is to treat the wounded."

Su Mubai and Lin Wan'er also knew that now was not the time to chase, so they nodded and began to check the injuries of Chu Mengmeng and Xiao Yichen.

However, at this moment, the last words left by the leader of the dark creatures before escaping made everyone's hearts sink.

"Just wait, the power of darkness will soon sweep across the entire world, and by then, you will all become our slaves!"

These words, like a bolt from the blue, echoed in everyone's ears. They realized that the resurgence of the dark forces was more serious than they had imagined, and a greater crisis was quietly approaching...

The roar of the dark creature leader was still echoing in the valley, but its huge body had disappeared into the darkness. Su Mubai held the energy gun and wanted to chase after it, but was stopped by Xiao Yichen.

"Don't chase a desperate enemy." Xiao Yichen covered his bleeding shoulder, his face pale but still calm. "It's injured and won't come back for a while. Let's treat its injuries first, and at the same time figure out what the 'dark power' it mentioned is."

Chu Mengmeng had fallen into a coma due to her severe injuries and was held in Xiao Yichen's arms. Su Mubai and Lin Wan'er also suffered minor injuries. After a simple treatment, the four decided to return to the city guardian's base first.

The atmosphere in the base was solemn. Chu Mengmeng was sent to the medical room. Xiao Yichen refused treatment and sat outside the medical room with a gloomy face. Su Mubai and Lin Wan'er were sorting out the information about the battle.

"Dark power...could it be referring to the source of power behind those dark creatures?" Lin Wan'er frowned, her delicate face full of worry.

"Those dark creatures seem to be more powerful than before." Su Mubai adjusted the energy gun and said in a deep voice, "Moreover, they seem to have some kind of intelligence. They are no longer the monsters that only know how to kill."

Xiao Yichen remained silent, his mind echoing with the words of the dark creature leader before he left: "The power of darkness will soon sweep across the entire world, and by then, you will all become our slaves!"

This sentence is not just a threat, it is more like a prophecy, or a declaration of war!

"Yichen, what do you think?" Su Mubai couldn't help but ask when he saw Xiao Yichen remained silent.

Xiao Yichen raised his head with a firm look in his eyes: "We must find out what the dark forces are and what their purpose is."

"But where should we start?" Lin Wan'er asked.

"I remember that there seem to be some records about ancient legends in the city library. Perhaps we can find some clues from them." Xiao Yichen said after pondering for a moment.

"You mean, those legends about the 'Dark Age'?" Su Mubai asked.

"That's right." Xiao Yichen nodded. "Legend has it that before the birth of human civilization, the world was ruled by the power of darkness. Later, the power of light defeated the darkness and sealed it away. But now it seems that the power of darkness is reviving..."

The next day, after Chu Mengmeng woke up, she insisted on going with Xiao Yichen to investigate the source of the dark power, despite the doctor's dissuasion. So the two came to the city library and began to read those ancient documents.

They searched through the vast sea of ​​books for a whole day, and finally found a record about the "Dark Age" on a worn parchment scroll:

"When the Dark Portal opens, the dormant evil will descend again, and the world will fall into endless darkness..."

Below this text, there is a strange pattern, which looks like a huge door with all kinds of strange runes carved on it.

"The Dark Portal..." Chu Mengmeng murmured to herself, "Could this be the source of the dark power?"

Xiao Yichen carefully observed the pattern on the parchment scroll. Suddenly, his pupils shrank sharply, as if he had discovered something incredible.

"What's wrong?" Chu Mengmeng noticed that Xiao Yichen was acting strangely and asked quickly.

"This door..." Xiao Yichen pointed at the pattern on the parchment scroll and said solemnly, "I seem to have seen it somewhere..."

At this moment, the door of the library was suddenly pushed open, and a familiar figure appeared at the door. It was the "dead" Xiao Yifeng!

"Long time no see, brother." Xiao Yifeng had an evil smile on his face. In his hand, he held a black stone that exuded a strange aura.

And the shape of the stone was exactly the same as the keyhole of the "Dark Portal" on the parchment scroll!

Xiao Yifeng's sudden appearance stunned Chu Mengmeng and Xiao Yichen. The library was silent, with only the ancient pages gently turning in the breeze, as if telling a long-lost story.

"You...you haven't already..." Chu Mengmeng pointed at Xiao Yifeng in surprise, unable to speak for a long time.

Xiao Yifeng smiled evilly, his eyes revealing a chilling coldness: "I'm sorry to disappoint you, I'm not that easy to die." His eyes fell on the parchment scroll in Xiao Yichen's hand, "It seems that you have found clues about the 'Dark Portal'."

Xiao Yichen calmly put away the sheepskin scroll and stared at Xiao Yifeng vigilantly: "What do you want to do?"

"What?" Xiao Yifeng sneered, "Of course, to open the 'Dark Portal' and let this world return to the embrace of darkness!" He raised the black stone in his hand, "This 'Key of Darkness' is the key to opening the 'Dark Portal'."

Chu Mengmeng then noticed the black stone in Xiao Yifeng's hand. Its shape was exactly the same as the keyhole of the "Dark Portal" on the parchment scroll. Moreover, judging from the strange aura emanating from it, it was definitely not an ordinary stone.

"Why are you doing this?" Xiao Yichen asked in a deep voice, "Do you know what it means to open the 'Dark Portal'? This world will be swallowed by darkness, and everyone will become a slave to darkness!"

"So what?" Xiao Yifeng's eyes became crazy and paranoid, "This world should have belonged to darkness! And I will be the master of darkness!"

"You're crazy!" Chu Mengmeng couldn't help but yelled, "You're willing to sacrifice the whole world for your own ambition!"

Xiao Yifeng ignored Chu Mengmeng. He stared at Xiao Yichen with a look full of resentment and hatred: "Xiao Yichen, you will always be a stumbling block to me! But it doesn't matter. Once I open the 'Dark Door', you will be nothing!"

After saying that, Xiao Yifeng did not stay any longer. He turned around and turned into a black shadow, disappearing into the depths of the library.

"Chase!" Xiao Yichen made a prompt decision and took Chu Mengmeng to chase in the direction where Xiao Yifeng disappeared.

Outside the library, Su Mubai and Lin Wan'er had been waiting for a long time. When they saw Xiao Yichen and Chu Mengmeng chasing a dark figure, they immediately realized what had happened.

"It's Xiao Yifeng!" Su Mubai exclaimed, and immediately raised his energy gun and shot at the black shadow.

However, the black shadow was so fast that it disappeared into the night in the blink of an eye and was nowhere to be seen.

"Damn it, he got away!" Lin Wan'er said hatefully.

"Where did he go?" Su Mubai asked.

Xiao Yichen's face was solemn, and he pointed to a barren mountain outside the city: "According to my perception, he should have gone there."

"Then what are we waiting for? Let's chase him!" Su Mubai said, and was about to run towards the barren mountain.

"Wait," Xiao Yichen stopped him, "It's very dangerous there, we have to think long-term."

Chu Mengmeng also nodded and said, "That's right. Since Xiao Yifeng dared to go there alone, he must have made some preparations. We can't act rashly."

"Then what should we do now?" Lin Wan'er asked anxiously.

Xiao Yichen pondered for a moment, then said with a firm look in his eyes: "Let's go back to the base first, gather everyone, and then go to that place together!"

He had a hunch that the matter between Xiao Yifeng and the "Dark Gate" was not that simple. What they were about to face would be an unprecedented challenge!
