To him, it wasn't difficult, yet Ian perceived that over five years, the Terra Cradle had traveled a considerable distance across the universe, causing certain changes in the space-time axis.
Nothing unusual, Ian thought, a cradle isn't stationary, just like the Solar System seems still but sways at the edge of the galaxy. As long as the observational perspective is broad enough, even the entire universe will sway like bacterial colonies in a petri dish.
However, after slightly sensing Terra Cradle's movement speed, Ian suddenly froze.
"Five light-years..."
He murmured, "Moved five light-years in five years..."
What?
For a moment, even Ian didn't understand what this meant—five years moving five light-years is just light, right? Quite normal, superluminal speed is so simple in the Aether Universe that light-speed movement seems merely mundane; besides, in Terra, even the Third Energy Level's Sunbird can barely force light movement.
But here's the issue.
