"Forces from Penglai Immortal Island?"
Yao Qinghe and the others stopped their alchemy, looking surprisingly at Yao Hun.
"Penglai Immortal Island?" Gu Chenfeng frowned slightly.
Yao Hun respectfully said, "Ancestor, I'm not familiar with Penglai Immortal Island, I've never been there, but I know that Penglai Immortal Island is extremely powerful."
Gu Chenfeng shook his head and said, "In the past, I have faced practitioners from Penglai Immortal Island, indeed their strength isn't weak, but I am also unfamiliar with Penglai Immortal Island."
Penglai Immortal Island is located on a vast island in the east of the Cultivation Realm, its existence is extremely mysterious.
Even Gu Chenfeng is unfamiliar with Penglai Immortal Island.
In the eighth life, Gu Chenfeng had been to Penglai Immortal Island, and had exchanges with its experts, yet it was only sparring.
