Nine-dimensional spacetime had a fluid quality to it!
It rushed in one direction like an endless river. Its end was nowhere in sight; all Shi Ge Mu knew was that it flowed toward a patch of pure black.
Spacetime poured into that darkness without cease, as though it were a bottomless abyss swallowing every river!
Gravity! An immense gravitational pull dragged everything toward it!
Shi Ge Mu was now inside the so-called Time Corridor.
As the name suggested, time here was like a road.
It had what people once considered the properties of space: a series of evenly distributed regions, relatively still.
Space, on the other hand, flowed. It plunged toward the source of gravity at tremendous speed.
Shi Ge Mu clearly "wasn't moving," yet she felt as though she were hurtling along at breakneck speed.
Time and space, the two fundamental properties of spacetime, had switched roles! In lower dimensions, flying in any direction through the universe meant moving across space. Whether one flew, slept, or ate, time kept passing...
Now it was the other way around.
Whether Shi Ge Mu moved or not, space swept past her like sand slipping through her fingers.
Shi Ge Mu faced the immense source of gravity. The pure darkness loomed like a giant beast, drawing closer and closer!
It seemed like the most terrifying thing in the world, the ultimate end of the universe. Just looking at it weighed on her mind.
Whatever she did, it kept approaching. Slowly, yes... but it would reach her eventually! Much like time as she had once known it, the space she occupied was now a river flowing relentlessly forward, never to reverse.
Shi Ge Mu calculated the distance. If she defined her own height as one kilometer, she was "360 billion kilometers" from the source
