On the seventh day after the strategy department came up with the plan, about 72 emergency-created pilotless spaceships left the City of Light Moon. Each of the spaceships was equipped with a superlight speed communication device and surveillance device. If they managed to detect something, even if just for one over fifty seconds, the information would be sent to the City of Light Moon. Therefore, it was okay if these spaceships were destroyed, because a great amount of information would still be sent back. If contact was made without hostility, even if there was no one piloting the spaceships, communication could be made without delay.
"There are in total 72 spaceships. They will separate into three groups, so unless the other party has decided to attack us directly, all three groups of armless communication spaceships won't be destroyed on sight."
