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

The light of the altar gradually faded, and the valley returned to its former tranquility. Chu Mengmeng and the others bathed in the afterglow, feeling the power surging in their bodies. This power was warm and powerful, as if it contained the energy to create the world, which gave them more confidence.

"Is this the 'source power' recorded in ancient books?" Lin Wan'er exclaimed, holding a crystal clear sword in her hand. The sword body emitted a light blue light. It was a new weapon condensed with "source power".

"It seems that our bet was right," Su Mubai murmured, "With this power, we have the capital to fight against it."

Xiao Yichen nodded slightly, looking into the distance with deep eyes, "It's time to take the initiative."

They decided to use the newly acquired energy source to create a batch of powerful weapons and equipment to equip themselves and other city guardians. Under the command of Chu Mengmeng, the craftsmen worked day and night to integrate the "source power" into various weapons and defensive equipment, greatly improving the combat effectiveness of the city guardians.

At the same time, Xiao Yichen developed a formation that can amplify the "source power" based on the ancient formation diagram, and arranged it around the city. This formation can connect the "source power" of all city guardians together to form an indestructible barrier to resist enemy invasion.

After everything was ready, the city defenders decided to take the initiative and launch a counterattack against the enemy.

The moment the battle started, the sky and the earth changed color.

Chu Mengmeng held a long whip made of "source power" in her hand. She was light but contained great power. She swung the whip, and every swing brought a gust of wind, sweeping the enemy into the air and then throwing him heavily to the ground.

Xiao Yichen held a long sword emitting golden light, and his sword energy was overwhelming. He was like a god of war, shuttling through the enemy's formation, and each sword accurately hit the enemy's vital points, and no one could stop him.

"Boom——"

With a loud bang, the huge body of the enemy leader fell to the ground, stirring up a cloud of dust.

"We won!" Lin Wan'er shouted excitedly, her face filled with the joy of victory.

However, Xiao Yichen did not relax his vigilance. He looked into the distance with a frown on his face. "It's not over yet. The real battle has just begun..."

On the battlefield filled with gunpowder, Xiao Yichen's words were like a warning bell, reminding everyone that the horn of victory had not yet been blown. He keenly realized that although the enemy leader had been eliminated, the enemies hiding in the dark were still eyeing them, and the battle was far from over.

"Mubai, Wan'er, take your men to cut off the enemy's supply line!" Xiao Yichen made a prompt decision and issued new instructions to Su Mubai and Lin Wan'er. He knew that the enemy was large in number and a protracted war would be disadvantageous to them, so they had to fight quickly.

"Understood!" Su Mubai and Lin Wan'er took the order and immediately led an elite team, bypassing the main battlefield and rushing towards the enemy's rear. They shuttled through the dense forest like ghosts, relying on their familiarity with the terrain and tacit cooperation, quietly approaching the enemy's supply team.

"Kill!" With one order, the team led by Su Mubai and Lin Wan'er rushed down the mountain like a tiger, unstoppable, and instantly killed the enemy by surprise. The enemy's supply team was defeated, supplies were scattered all over the ground, and the blazing flames illuminated half of the sky.

After cutting off the enemy's supply line, Su Mubai and Lin Wan'er did not linger in the battle, but quickly retreated back to the main battlefield. Their actions greatly boosted the morale of the city defenders and also caused the enemy to panic.

At the same time, the guardians of the ancient ruins also played a vital role. They used ancient knowledge to set up a huge magic circle to trap the remaining enemies in a specific area. The magic circle exudes a dazzling light, forming an insurmountable barrier that firmly traps the enemies.

"Roar—" The trapped enemies roared angrily, but could not break through the magic circle. They attacked the magic barrier frantically, but like moths to a flame, their efforts were in vain.

Looking at the trapped enemy, Chu Mengmeng and the others felt a glimmer of hope. However, Xiao Yichen's brows were still furrowed, his eyes were deep and solemn, as if he had a premonition that a greater challenge was waiting for them...

Xiao Yichen's premonition was soon confirmed. Just as the magic circle of the guardian of the ancient ruins was about to collapse, an even more powerful force descended from the sky, landing in the center of the battlefield like a miracle.

Along with dazzling light, a mysterious cloaked figure slowly descended. His appearance shocked everyone present. Both the city guardians and the trapped enemies had never seen such a powerful force.

"That is..." Chu Mengmeng opened her mouth in surprise. She could feel the powerful aura emanating from the mysterious man. It was an unimaginable energy fluctuation, as if it came from another world.

"Don't panic, we are here to help you." The mysterious man's low voice rang in everyone's ears. His tone was calm and gentle, but with an unquestionable majesty.

Before he finished speaking, the mysterious man gently raised his hand, and an invisible force instantly spread out. The magic circle that was about to collapse was stabilized, and the enemies trapped in it let out miserably screams. Their bodies quickly disintegrated under the powerful energy impact, and eventually turned into ashes and disappeared into the air.

The appearance of the mysterious ally completely reversed the situation, and the city guardians, who were originally in danger, finally breathed a sigh of relief. Su Mubai and Lin Wan'er led the team back to the main battlefield. They looked at the incredible scene in front of them, their eyes full of awe and gratitude.

"Thank you for your help, senior!" Xiao Yichen stepped forward and bowed deeply to the mysterious man. He knew that without the help of this mysterious ally, it would be difficult for them to escape unscathed today.

"No need to be polite. It is our responsibility to protect this city." The mysterious man said calmly, "This battle is just the beginning. The real threat is still to come. You must be prepared."

After leaving a meaningful word, the mysterious man once again turned into a stream of light, soared into the sky, and disappeared into the clouds.

The city defenders looked at each other in confusion. They didn't know what the "real threat" that the mysterious man was talking about was, but they understood that a bigger storm was coming.

After this battle, the city defenders successfully recaptured the area occupied by the enemy, and the panic in the city gradually subsided. However, Xiao Yichen's heart was still restless. He always felt that something was beyond his control, and a feeling of uneasiness lingered in his heart.

Just as the city defenders were preparing to celebrate their victory, a huge crack suddenly appeared in the sky. The crack exuded a heart-pounding dark aura, as if it was connected to another unknown world.

“What is that?!” Chu Mengmeng exclaimed, pointing at the crack in the sky, her face turning pale.

Xiao Yichen's heart suddenly sank. He realized that the "real threat" that the mysterious man mentioned had finally arrived...
