Chapter 2259: "Sacrificing The Mimicry Domain" 

The domain masters can save the soul masters and return to the main world in advance before the domain really explodes. 

As for the rest of the transmigrators? Although it is a pity that they would probably die, their souls might not really be destroyed in the explosion. 

At most, they would be heavily injured, but then, they would definitely have to go to the nearest world to occupy a body or cultivate their souls to a certain state before they could occupy a new body. 

There were also a lot of transmigrators who didn't know how to cultivate their souls and occupy bodies.

For these unfortunate souls, if they were valuable, the world union could consider hiring soul experts and domain masters to go to the fourth void and pick up these souls for other uses. 

Actually, a lot of leaders from various races didn't really agree with this cruel plan, including the current elf king.
