A Strange Portal

'Strange, why am I getting a feeling that something is calling me? Is there someone trapped inside the formation?' Yuan wondered, confusion written all over his face.

With a puzzled look, Yuan walked up to the formation and stretched his arm forward. As soon as his hand touched the formation, the area began to shake violently, panicking everyone at the scene.

"What is happening? Why is there an earthquake all of a sudden?!"

"Is there another group of monsters approaching us?" 

People were shocked and began to scream, terrified about the possibility of another group of powerful monsters attacking them.

But suddenly, the formation began to glow with a bright golden light, attracting everyone's attention toward the secret chamber. People stared at the secret chamber with dumbfounded looks on their faces.
