Chapter 661: How Utterly Naive

"It worked!" Li An shouted excitedly.

However, just at that moment, the mysterious figure suddenly revealed an eerie smile. With a wave of both hands, a wave of black energy radiated from his palms, instantly enveloping Li An and Guo Yao within it.

"You think you can defeat me like this? How utterly naive." The mysterious figure's voice echoed within the black energy wave.

Li An and Guo Yao were startled; they knew they had fallen into danger. They had to find a way to break through this black energy wave as quickly as possible, or they would both be defeated by the mysterious figure.

Under the shroud of the black energy wave, both Li An and Guo Yao felt tremendous pressure. Their breathing grew rapid, and sweat kept streaming down their bodies.

"We have to find a way to break through this black energy wave," Li An said through gritted teeth.

Guo Yao nodded. She looked at Li An, a glint of resolve flashing in her eyes: "I believe in you, Li An. We will definitely find a breakthrough."

Saying so, Li An and Guo Yao began observing their surroundings. They discovered that this black energy wave seemed to be composed of a special kind of energy, and this energy bore some resemblance to the power they had seen in the ruins.

"I remember seeing a method in the ruins that could break through this kind of energy," Li An suddenly said.

Guo Yao's eyes lit up: "Really? Then let's try it quickly."

Li An nodded. He closed his eyes and began recalling the method he had seen in the ruins. Then, he opened his eyes, waved his hands in the air, and mysterious runes began to appear in the void.

"Guo Yao, coordinate with me; let's perform this method together," Li An said.

Guo Yao nodded. She tightly gripped Li An's hand, channeling her own power into his body. Then, she too closed her eyes and began silently reciting an incantation.

With Li An and Guo Yao's joint effort, those mysterious runes began to emit a dazzling light.

The night was ink-black, neon lights flickered in every corner of the city, cloaking this bustling metropolis in a layer of mystery. Li An and Guo Yao had returned from the outskirts, their shadows stretching long under the streetlights, making them exceptionally conspicuous. Their mood had not relaxed upon returning to the city; on the contrary, it had grown even heavier. Having learned that the "Ancient Key" had been activated, the mysterious organization was plotting an even greater conspiracy, and they seemed to already be standing at the eye of the storm.

Li An gripped his phone tightly; the screen flickered with a message from the mysterious organization, and a look of resolve and determination shone in his eyes. Guo Yao pressed close to him, feeling the turmoil within his heart. She gently held Li An's hand, conveying wordless comfort through her gaze.

"An, we will definitely get through this crisis," Guo Yao said, her voice gentle yet firm, her eyes filled with trust in Li An.

Li An nodded slightly, the anxiety in his heart easing a little. He looked at Guo Yao, a faint smile curling at the corner of his mouth: "With you here, I fear nothing."

However, this peace did not last long. The moment they stepped into a narrow alley, a group of mysterious organization members in black uniforms and with sinister smiles suddenly surged out from all sides. Wang Qiang and Zhang Min stood at the very front of the crowd, their eyes brimming with hostility and cunning.

"Li An, your end has come!" Wang Qiang sneered, his figure lunging toward Li An like a phantom..
