Chapter 675: The Source of the Mysterious Power

Li An nodded, gripping the sharp blade in his hand tightly, ready to face the unknown danger approaching. The two continued forward, finally arriving at an open grassland. There stood an ancient altar on the grassland, with eerie light flickering upon it.

"It seems this is the source of that mysterious power," Li An said in a deep voice, his eyes revealing determination and resolve.

Just then, a powerful energy fluctuation suddenly surged from the altar, shaking both of them back several steps. Li An steadied his stance, staring fixedly at the altar, ready to welcome the coming challenge.

"Li An, be careful!" Guo Yao suddenly shouted. A black figure appeared on the altar, its whole body radiating an evil aura, as if a demon crawling out of hell.

Li An's heart tightened. He immediately unleashed his full strength and engaged the black figure in a fierce battle. Their figures darted quickly across the grassland, each collision accompanied by deafening sounds. Trees around them fell one after another under their attacks, and the air was permeated with density of dust and gunpowder smell.

Li An fought with increasing courage, every move of his containing immense power. Yet the black figure was no weakling either; its attacks were equally ferocious. They exchanged blows back and forth, locked in an indecisive struggle.

Just then, Li An suddenly felt a familiar power surging within his body. Joy filled his heart, and he quickly merged this power with his internal energy. Instantly, his strength surged greatly, and a dazzling light radiated from his entire body.

"Take this!" Li An roared. His figure shot upward like lightning, charging at the black figure. The sharp blade in his hand flashed like electricity, every strike aimed directly at the black figure's vital points.

The black figure was shocked and terrified; it never expected Li An's strength to be so formidable. It immediately unleashed all its tricks, attempting to block Li An's attacks. However, Li An's strikes came like a relentless storm, leaving it utterly powerless to defend.

Finally, after one fierce collision, the black figure was split in two by a single slash from Li An. Its body turned into a wisp of black smoke and vanished into the air. The light on the altar also disappeared, as if it had never existed.

Li An stood in place, his panting echoing through the silent forest. He turned to look at Guo Yao and saw a relieved smile on her face.

In the mysterious forest shrouded in thick fog, Li An and Guo Yao walked side by side, every step taken on the edge of the unknown and danger. Li An's eyes were firm, a hint of unyielding resolve hanging at the corner of his mouth, while Guo Yao followed closely, her eyes holding both fear of the unknown and deep trust in Li An.

"An, this fog is so thick; I can't see anything," Guo Yao's voice trembled slightly. She unconsciously moved closer to Li An, as if drawing a shred of courage from him.

Li An tightened his grip on Guo Yao's hand, feeling the slight coolness of her palm, and a warm current surged in his heart. "Don't be afraid; I am here." His voice was low and powerful, as if it could pierce through the fog and reach straight to Guo Yao's heart.

Suddenly, the ground trembled slightly, and then several hidden traps quietly revealed their ferocious forms. Li An's eyes instantly sharpened. He yanked Guo Yao hard, and the two narrowly avoided the traps' deadly edges.

"Be careful!" Li An warned in a low voice, while cautiously scanning the surroundings, as if ready to face any danger that might appear at any moment.

Guo Yao's heart raced, but she did not retreat. Instead, she pressed even closer to Li An, expressing her determination and support through her gaze.
