Another month passed, and Peng Tianlei flew through a dark forest filled with various kinds of black trees and plants. The forest was filled with the howls of various beasts. In the sky above the forest, several giant flying beasts circled there, but they did not dare to approach the heavenly thunder roc.
"Where is that castle? Why can't I see it even using my void eyes?" Ling Yun's clone asked.
"Haha." Peng Tianlei shot something from his mouth, and a giant dome appeared in front of them, revealing the majestic Black Dragon Castle inside. "That's the castle, Master. The old dragon created this dome with the help of the first void spirit, and she made it impregnable to anyone. Only the old dragon's loyal followers and Huang Lingzhu can enter this place, which preserved the layout of the castle as it was originally built."
