Looking at the surroundings that had shifted back to normal, Bai Zhi pondered for quite a while.
The footage from before had not been long in total, only four or five minutes at most, but the amount of information revealed in those few minutes was immense.
The reason this Grotto-Heaven and Blessed Land had been abandoned and sealed off was a disaster that had erupted in the central area. Everyone caught within the disaster's range would vanish collectively, just like the two Medicine Boys he had seen in the herb field earlier.
And judging from the conversation between those Medicine Boys, that disappearance had been a disappearance in the truest sense—as if the entire person had been completely erased from the world. Even Immortals had been unable to escape it.
Although he did not know what level the Immortals mentioned by the Medicine Boys represented in the present day, as beings who occupied the area with the densest Spiritual Energy in this Grotto-Heaven and Blessed Land, they could not possibly have been weak.
Yet even beings like that had been utterly powerless before that disaster... A Meme?
As if he had suddenly thought of something, Bai Zhi frowned slightly.
Based on what he currently knew, disasters in this era could generally be divided into three categories.
The first was disasters of [Evil Gods].
Disasters of Evil Gods could also be called anomalies brought about by Evil Gods and the worlds inhabited by those Lords of Anomaly beneath them. This was also the most widespread type of disaster across the many worlds.
The second was disasters of [Apocalypse].
As the greediest Predators in the Void, Apocalypses were intensely hated even by the Evil God anomaly faction. Although the two sides generally kept out of each other's way, that was not absolute.
