Nether Ghost Abyss Realm

The mist occasionally stirred, as if something wanted to break free from below but was held back, it only letting out low, angry roars.

The roars were soft, but Amalia could still hear all kinds of strange, complex sounds mixed in.

"Is there a barrier around the Nether Ghost Abyss Realm?"

Tian Wuya nodded. "Yes. In order to prevent the Devil Ghosts from escaping and harming the world, powerful Immortals from the ancient times joined forces to create a barrier."

Amalia looked curious. "Master, can any barrier, no matter how strong, still hold after so many years?"

"The techniques that was used by the Immortals are beyond our imagination. From what I know, several mighty Immortals even sacrificed themselves to permanently seal the Nether Ghost Abyss Realm," Tian Wuya explained. "This is the responsibility of the strong. When you have great power, you will also have great responsibility."
