"Hand Seals Formation" 

Ainsley and the others didn't know that fifty people died quietly, but they all could feel the domain becoming more and more unstable, as if on the edge of breaking apart. 

It was indeed good for the domain to be unstable like this, which gave the transmigrators a chance to escape and return to the real world. 

However, if one accidentally stepped out of the domain without finding a way back to the real world, instead of returning immediately, they would only enter the chaotic and abstract fourth void. 

So far, no one could live in the fourth void without the protection of domains or natural tunnels that people used when moving from one space to another. 

The damage to the domain did harm a few mid-level transmigrators who weren't that proficient in space and time, directly killing these people within seconds.
