Shattered Dimension
It can be simply understood as a 'gap' between worlds, which expands over time due to the movement of matter.
However,
the myriad worlds directly associated with the Black Tower have established [channels] with it and undergo annual stability checks and maintenance on these channels.
It's like the Black Tower serves as a central point, drawing sturdy ropes to hold these worlds, keeping their distances constant.
Therefore.
Apart from S-01, the 'gaps' between other worlds are very small,
if one breaks through the boundary membranes of these worlds and conducts rapid transitions through the Shattered Dimension, they won't travel far before reaching the boundary membrane of another world.
But S-01 is different,
as it lost contact with the Black Tower for years,
with ongoing expansion,
S-01 has distanced itself from the Black Tower and other worlds significantly, with gaps thousands or tens of thousands of times larger than other worlds.
