It was already an extremely difficult thing for Gu Immortals to pass a regional wall.
However, at this time every year, because of the earth tide, Eastern Sea's regional wall would become weaker and thinner, and Gu Immortals of Central Continent, Northern Plains and Southern Border could take this chance to enter Eastern Sea.
Naturally, there were also a few Eastern Sea Gu Immortals that took this chance to enter Central Continent, Northern Plains or Southern Border.
Thus, it was not a strange thing for Gu Immortals of these three regions to come to Eastern Sea.
However, it was rare for Western Desert Gu Immortals to be in Eastern Sea. Western Desert and Eastern Sea were separated by the other regions in the middle. It would definitely be eye-catching if a Western Desert Gu Immortal appeared in Eastern Sea.
