Chapter 658

Li An and Guo Yao looked at the light ahead, their hearts swelling with excitement. They knew they had finally found the Ancient Key.

They approached the light cautiously, afraid of disturbing it. When they finally reached the light, they saw the true form of the Ancient Key.

It was a key made of unknown material, emitting a faint blue glow. Its shape was strange and intricate, as if imbued with some mysterious power.

Li An and Guo Yao gazed at the key, their hearts filled with awe. They knew this key was the key to unlocking all mysteries.

Yet just then, a figure suddenly burst from the darkness, racing toward the Ancient Key. Li An and Guo Yao both gasped in shock and swiftly blocked the figure's path.

The figure wore a black robe, his face hidden in the shadow of his hood. His eyes glowed with greed, as if determined to claim the Ancient Key for himself.

"Who are you? How dare you steal the Ancient Key!" Li An shouted.

The Sky City's final line of defense stood before Li An and Guo Yao like an insurmountable wall. Li An's eyes burned like flames as he fixed them ahead, an unprecedented fighting spirit surging within him.

"Looks like we'll have to show our true strength," Li An said, his voice low and firm. He took a deep breath and instantly transformed into a streak of light, charging straight at the defense.

Guo Yao followed close behind, her eyes flickering with trust and concern for Li An. She knew his resolve was unshakable; she could only support him fully.

Li An's fists gathered immense power, like two brilliant stars, crashing down upon the defense... yet the defense, like an indestructible steel plate, swallowed his attack whole without so much as a tremor.

"Damn it!" Li An roared, unable to accept how feeble his attack had been.

Seeing Li An repelled, Guo Yao grew frantic. Ignoring her own safety, she joined the assault, her hands dancing as mysterious runes bloomed in the air, trying to break through the defense.

"Li An, I'm helping you!" Guo Yao's voice carried a note of finality.

Yet their attacks still had no effect, instead provoking a fierce counterattack. Waves of intense energy surged like a raging tide, forcing Li An and Guo Yao into steady retreat.

Li An and Guo Yao tumbled through the air, barely steadying themselves. Their faces bore grave expressions; they knew the challenge before them was far stronger than they had imagined.

"We need to find a way to break this stalemate," Li An gasped.

Guo Yao nodded, her gaze lingering on Li An for a moment before she said firmly: "I believe in you, Li An. We will find a breakthrough."
