Chapter 819: The Fate of Cultivators is to Go Against the Heavens_1

The grand army of flying boats came to a halt at the edge of Yin Yang Valley.

No one dared to enter recklessly.

The peculiar poison of Yin Yang Valley is not to be taken lightly.

"Roar!"

As everyone watched, a sudden earth-shattering roar echoed from the depths of Yin Yang Valley, causing the entire ground to tremble with the sound.

In the sky, leaders of various factions appeared from their flying boats, gathered together, and began discussing.

Li Ping'an observed for a while and then said, "Without a way to defend against the strange poison, it's not considered a divine treasure. We can only watch from afar. Let's go."

The flying boat quietly left the main force and headed north along the edge of Yin Yang Valley.
