Chapter 596: The 'God' Prowling the Void
In the world of Erathia, all powers with the ability to colonize the Void tend to be exceedingly moderate when wielding warfare to conquer other worlds. If unnecessary, they would never use weapons of mass destruction or biochemical weapons that could irreversible harm to the world, and always try to keep slaughter within certain limits.
Because once the destruction inflicted upon a world exceeds a certain threshold, the world teetering on the edge of annihilation will conjure a will, and then emit anguished laments and cries for help which only entities like the Epic can hear.
And then there is no aftermath. In the world community where Erathia resides, once a world issues its wail of despair, the legion that damaged the world can basically declare its end, because Epics would inevitably respond to the world's cries for help.
