The name Lights Miniature Galaxy was actually a suicide bomb. There were no elements of bombs on the surface. Occasionally, when the sub-space field overlapped with the real universe, one could even see the starlight emitted by the internal stars.
However, if someone really tried to bring this Miniature Galaxy back for research, what awaited him would only be an explosion.
The star hidden inside was a time bomb that was about to explode. When the time was up, this star would explode, sealing off the sub-space and blasting open the Miniature Galaxy.
After detonating in this way, the aftermath of the supernova explosion alone could destroy all the lives nearby, not to mention that the shockwave would spread the large number of poisonous substances stored inside to further places.
Obviously, this Lights Miniature Galaxy was designed to make the enemy think that the Sentry Organization was hiding there.
