At Lü Yongchang's command, the unmanned Survey Ship fleet conducting routine patrols in a nearby star region hurried to the Dead Silent Region without delay.
The fleet consisted of three Survey Ships.
The reason for dispatching them to the Dead Silent Region was simple-to conduct a more thorough investigation of the area where Probe Ship 129C had disappeared.
Research into Klein bottles had been ongoing for more than three hundred years.
It was no exaggeration to say that the Dimensional Laboratory and the Spacetime Research Institute had manufactured well over a hundred thousand Klein bottles.
Though most were defective specimens that lasted only a few seconds or less.
But all those Klein bottle structures shared one defining feature:
Every Klein bottle with an entrance had an exit!
To date, humanity had never discovered a Klein bottle without an exit.
It was just that... its exit could end up in some bizarre places.
Unlike electromagnetic wave communication and quantum communication, tachyon communication offered excellent stability, high speed, and strong resistance to interference.
On top of that, the Academy of Sciences used tachyon signal receivers of the highest precision.
Lü Yongchang was confident that as long as Probe Ship 129C appeared within ten thousand light-years, the Academy of Sciences would quickly receive its signal.
But there was a problem.
Probe Ship 129C had been missing for over forty-eight hours.
The Academy of Sciences had yet to receive a tachyon signal from Probe Ship 129C.
This meant the situation might be far more complicated than Lü Yongchang and the others had initially estimated.
Lü Yongchang sat with his brow tightly furrowed, scrutinizing the holographic projection before him.
Over the past few days, he and the academicians had repeatedly reviewed all the data Probe Ship 129C had sent back before disappearing, trying to find
