The space ripples raised by the wormhole bomb expanded into a gigantic swirl more than eighty kilometers in diameter in only ten seconds. Together with all the 'impurities' that were enshrouded inside, it was crystalized first and then became an ivory light ball. The light ball then perished in a moment, reducing into a singular point that was unobservable in the three-dimensional universe.
Centered at the singular point, all the materials within thirty kilometers vanished. They were either teleported to the other side of the universe billions of lightyears away or paved evenly in every corner of the universe, leaving a spherical area of 'vacuum' true to its meaning. It was so dark and so pure that the area was the best example of 'obliteration'.
The materials between thirty to fifty kilometers from the center suffered severe space-time twisting, too. Parts of them were teleported.
