"What did you say?" Luu asked with a puzzled expression on his face.
"I heard something," Lucas replied, "a whisper..." Lucas's mouth froze as if he couldn't say any more words
Luu looked at Lucas and then turned his head. Slowly, they moved towards the direction of the sound. When they arrived, they stood next to each other and listened carefully.
"Hello, Lucas..." The voice repeated.
The voice sounded familiar. Lucas could hear a hint of sadness in it, mixed with sorrow. There was only one person who spoke to Lucas like this.
"Who are you?" Luu interrupted, "Lucas, step back!" Master Luu raised his hands and took a defensive stance.
Lucas knew it was dangerous to approach the figure and he was about to shout at Luu to stop. But just when he was going to speak, the figure disappeared.
"Did you see it?!" Lucas yelled.
"No," Luu answered, "I don't know what it was. Let's move, it might be dangerous."
