Chapter 659: Break This Stalemate

Under the fierce counterattack of the defense force, Li An and Guo Yao continuously dodged attacks, searching for an opportunity to strike. Their bodies were covered in wounds, but their gazes grew ever more resolute.

Suddenly, a flash of inspiration struck Li An's mind—he remembered a way of wielding power he had mastered in the ancient ruins. He seized Guo Yao's hand and pulled her close.

"Guo Yao, do you remember the totem of power fusion we saw in the ruins?" Li An's voice carried a hint of urgency.

Guo Yao paused briefly, then quickly responded: "You mean, we could try fusing our powers together?"

Li An nodded, his eyes flickering with hope: "Yes, only this way can we break this stalemate."

Speaking thus, Li An and Guo Yao adjusted their breathing, gradually gathering their inner forces into their palms. Their hands clasped tightly, and a powerful energy ripple surged between them.

"One, two, three—fuse!" Li An roared. In an instant, their powers merged into a brilliant beam of light, lashing out at the defense force.

This time, their attack finally took effect. The defense force cracked, revealing a tiny fissure under the light. Though small, this gap was a vast hope for Li An and Guo Yao.

"We did it!" Li An cried out in excitement.

Guo Yao smiled, tears glistening in her eyes—tears of joy and emotion. She knew they had finally found a way to breach the defense.

The onlookers around them stared in shock. They could not imagine Li An and Guo Yao had shattered the defense force's barrier so easily.

Seizing the opportunity, Li An and Guo Yao dashed toward the Ancient Key. Their figures carved elegant arcs through the air, like two brilliant meteors.

The defense force, sensing their threat, launched even fiercer attacks. Yet Li An and Guo Yao showed no fear, using their fused power to repeatedly deflect each assault.

Finally, they reached the side of the Ancient Key. Li An drew a deep breath and poured all his power into it.

"Ancient Key, grant me strength!" Li An's voice echoed through the sky.

As Li An's power flowed in, the Ancient Key began to glow with blinding radiance. The light spread outward, engulfing the entire Sky City.

Guo Yao gazed at the scene before her, filled with awe and joy. She knew that at this moment, they had uncovered part of the secret of the Comprehensive Anime World.

Yet just then, a mysterious signal suddenly entered their ears. It brimmed with coldness and cunning, sending a chill through both Li An and Guo Yao.

"It seems someone already knows we've activated the Ancient Key," Li An said gravely.

Guo Yao nodded, her expression grave: "Yes, and their conspiracy appears far more complex than we imagined."

As they spoke, Li An and Guo Yao scanned their surroundings. They noticed the once-peaceful Sky City had begun to tremble; mysterious energies wove through the air, as if ready to unleash terrifying attacks at any moment.

"We must be cautious," Li An said.
