Ning flew through space at more than half the speed of light. This speed was not one that required him to use Energy at all and was instead something that was his skill after having bought it from the system's shop.
The speed at which he flew made time pass so much slower for him than the others who were back on the planet he had just left behind.
Dozens of years, if not more, would pass in the time a single year would pass for Ning. Still, even at this speed, it would take Ning over 5 years of his personal time to intercept the Constellation that was currently making its way somewhere.
Ning didn't know much about the constellation he was going to visit except for its name, Farhalys. He had given the system a very simple criteria so that he could acquire his energy.
