While the empire was thinking about the upcoming campaign, Nathan and the others had settled down on a planet outside the empire's surveillance.
"How is it going?" Nathan asked.
"Please take a look at this." Machina showed the new phone to Nathan. The phone looked like a combination of a smartphone and a military phone. It had a very big and long antenna on the side.
However, the interface looked similar to the smartphone that he knew.
"I can only make it to this level right now. The antenna here is transmitting a signal through a spacetime tunnel to reach a very far distance. Currently, the range is about three thousand light-years."
"That's not too far, if we're talking about cosmic scale." Nathan nodded in understanding. "What's the strongest one in the empire?"
"Military-grade phones should be around half a million light-years."
"Oh!" Nathan nodded, impressed by the scale.
