This way, when the Mechanical Disaster fleet returns in the future, they can retrieve these probes, conveniently read the information, and then know what Tom did in the star system during this period, and even… know which direction his fleet escaped to.
Just as it's impossible for even the Mechanical Disaster fleet to completely eliminate their spy probes, it's even more impossible for Tom to eliminate the spy probes left behind by the Mechanical Disaster fleet.
Space is too vast, and spy probes are too small.
Deep space will completely conceal their tiny forms, preventing them from being detected by the outside world.
Furthermore, the Mechanical Disaster fleet will certainly do this, because it costs nothing and is very effective.
So what should Tom do?
If the main fleet and the decoy fleet separate within the star system, it will not achieve any disguise effect, because those probes will surely detect which one is the real main fleet and which one is the decoy fleet.
