253 Explode Again

Ghost signal, this was a sword that had always been hanging over the head of the Milky Way civilization.

The beginning of this crisis was due to the spread of the ghost signal. Although it was not clear, the civilizations of the Milky Way still attributed the ghost signal produced by the Administrator a long time ago to this unexpected enemy crisis.

They believed that the unusual ghost signal must have had some unknown effect.
