It is said that the Ghostly Land is somewhat similar to the Hell Ghost Clan's cross-border Transmission Array, allowing the Hell Ghost Clan to pinpoint across realms more easily.
Previously, the Supreme Mysterious Immortal Sect suffered a ghost flame attack because an emerging Ghostly Land could not be cleared, attracting the Hell Ghost Clan to crossover....
Fortunately, that Hell Ghost Clan individual was just passing by and didn't intend to truly arrive at the Ten Heavens; otherwise, the Supreme Mysterious Immortal Sect would have long ceased to exist.
Even so, the ghost flame attack caused by the passing Hell Ghost Clan still inflicted terrifying damage on the Supreme Mysterious Immortal Sect.
Therefore, the Yuhua Immortal Palace also hopes to avoid such disasters.
The best method is to eliminate the Ghostly Land as much as possible.
But, clearing the Ghostly Land is extremely difficult.
In any case, the Yuhua Immortal Palace does not yet have such power.
