Water Moon Grotto-Heaven.
Like the Immortal Island, countless powerhouses had attempted to enter it over the years, only to end in failure.
No one had ever truly managed to fully explore it.
Yun Zheyue was one of the few people throughout the ages who had obtained Water Moon Fairy's inheritance.

As for the attacks unleashed by the formation, they were even less than an itch
