He asked, "Brother Meng, what is the Grotto Heaven and Avatar they mentioned?"
Meng Changgeng waved his hand and said, "Grotto Heaven is a blessed land occupied by the Immortal Sect, like a palace in the sky, rarely seen by us Loose Cultivators in daily life."
Fang Zhixing frowned and said, "So, the Grotto Heaven is actually a place for cultivation?"
Meng Changgeng continued, "The Immortal Domain is boundless, with many Time-Space Rifts in the vast starscape, each forming a world of its own, which is the Grotto Heaven!
These Grotto Heavens are of two kinds: one is naturally formed during the evolution of the universe; the other is created by a great power using astounding methods.
However, no matter the type of Grotto Heaven, it eventually gets taken over by various major forces, then developed and utilized."
Fang Zhixing pursued further, "How are they developed, and how utilized?"
Meng Changgeng shrugged and said, "I'm just a Loose Cultivator, how would I know so much."
