There had been two occurrences of spatial overlapping in the last two hundred years.
The first time happened on an important highway of a city, which caused countless cars to go missing. Not only that, this incident also caused the disappearance of an A-tier. Naturally, this had caused great panic among the general populace.
What made this phenomenon rather horrifying was that all spatial waymarks were rejected in these overlapping dimensions—thus, resulting in people who were transported away by the spatial overlap to not be able to return.
The place was thus designated as a forbidden zone. Five years after the incident, the A-tier who went missing finally walked out of the place. From the A-tier's point of view, he had struggled to live for ten years, causing his powers to be greatly enhanced along the way. However, all of his underlings that were following him that day were all dead.
