Chapter 656

Guo Yao nodded, her eyes shimmering with trust. She tightly grasped Li An's hand, as if trying to transmit all her strength to him.

Li An raised his right hand, palm facing up. A light gradually illuminated his palm; it was the energy within him gathering. He took a deep breath, then suddenly swung forward.

A massive energy beam shot from his palm, striking the defensive force directly. However, that defensive force seemed not to waver at all, remaining invincible.

Li An was startled in his heart and quickly withdrew his hand. Looking at the light in his palm that was gradually fading, he felt somewhat depressed: "It seems my strength is not enough."

Seeing this, Guo Yao quickly stepped forward, grasping Li An's hand: "Li An, don't be discouraged. If we work together, we will surely break through this defensive force."

Li An nodded, his eyes shimmering with determination. He raised his right hand again, preparing to launch an attack. However, just then, he suddenly felt a powerful force coming from behind.

He quickly turned to look, seeing Guo Yao standing behind him, her hands clenched into fists, her whole body radiating dazzling light. That force was emanating from within Guo Yao.

"Guo Yao, you..." Li An looked at Guo Yao in surprise.

Guo Yao smiled slightly, her eyes shimmering with determination: "Li An, don't forget, I am also a member of the Secret Organization. I have my own strength."

Hearing this, a warm current surged in Li An's heart. He looked gratefully at Guo Yao, then raised his right hand again. This time, he and Guo Yao launched an attack together.

Two massive energy beams shot from their palms, striking the defensive force directly. This time, that defensive force finally showed some wavering.

Seeing this, Li An and Guo Yao felt a surge of joy in their hearts. They continued to launch attacks, beam after beam of energy shooting from their palms, constantly bombarding the defensive force.

Under their attacks, that defensive force gradually became fragile. Finally, under a fierce bombardment, it collapsed with a boom, turning into countless energy fragments that dissipated in the air.

Li An and Guo Yao looked at the area ahead shrouded in energy fragments, a surge of excitement rising in their hearts. They knew the Ancient Key was waiting for them ahead.

They increased their speed, charging forward. However, just then, a more powerful energy fluctuation came from ahead. Li An and Guo Yao stopped their steps simultaneously, looking ahead warily.

A massive energy beam shot from ahead, striking the ground directly in front of them. The ground instantly exploded, with gravel and dust flying everywhere. Li An and Guo Yao quickly retreated, barely dodging the blow.

"What is going on?" Guo Yao asked in surprise.

Li An frowned tightly, his gaze sharp as he observed ahead: "It seems we have triggered the Sky City's final defense mechanism. This energy beam is preventing us from approaching the Ancient Key."

Hearing this, Guo Yao felt somewhat worried in her heart: "Then what should we do?"

Li An took a deep breath, determination shimmering in his eyes: "No matter how many difficulties lie ahead, we cannot give up. Guo Yao, stay close to me; we will rush through together."

Guo Yao nodded, her eyes shimmering with trust. She tightly grasped Li An's hand, as if trying to transmit all her strength to him.
