Chapter 1582: The Search Light.

This fight started about a month ago. It wouldn't have started if the Supreme Alliance didn't interfere because it was unlikely that the Origin gods of high heaven would be able to find them. Even if they did, they were unlikely to be able to keep him, and they probably won't tell others where he is so that they can monopolize him. 

But the Supreme Alliance didn't want that. They made the first move when he was inspecting the once-Virut plane for the points in space of alignment between the two realms while also keeping an eye on Salvini. 

Those points of spatial alignment will be where the cores of dungeons will be. The dungeons will form a tunnel between each realm, which they can use to invade each other.
