Eric curiously picked up the shiny box. As soon as he touched it, the box opened automatically, and inside was a crystal - clear crystal ball.
Just then, the old man in the black robe suddenly appeared at the door, and said with a gloomy face, "This is not something you can touch!" Eric quickly explained that he was just curious. The old man was silent for a moment, then slowly said, "This crystal ball has mysterious powers. It can guide you to find the way out of here, but it may also bring great danger."
Eric was not intimidated by the old man's words. He firmly said that he was willing to use the power of the crystal ball to move forward. The old man sighed helplessly and told Eric how to use the crystal ball.
Eric held the crystal ball in both hands and silently prayed in his heart. The crystal ball gradually emitted a light, and in the light, a passage leading to the depths of the castle appeared. Eric took a deep breath and resolutely walked into the passage.
There was a pungent smell in the passage, and the walls were flickering with strange lights. Eric walked carefully, and suddenly heard a low growl.
