The Observers' special structure allowed them to remain unaffected by the power of the apocalypse. But at the same time, lacking sufficiently powerful anchor points, they were unable to interfere with the material world in any way.
Put simply, to the spacetime of the universe, they were almost nonexistent.
They and the material world existed in a relatively parallel state.
This unique nature made them Observers, made them Recorders, used to observe and explore one spacetime after another that had fallen under the apocalypse's assault, gathering relevant data.
The multiverse was vast and boundless. By chance, special things would always arise, possessing a degree of resistance to the apocalypse.
At this moment, they had sensed the vast fluctuations transmitted through deep space. Within this universe now dying away, this fluctuation brimming with "vitality" was so conspicuous, seeming utterly out of place with the entire world.
Their structure had undergone special tuning. Apart from those nearly imperceptible traces of traits that transcended dimensions, their within-dimensional structure was primarily used for detection. Even beneath the obscuring power of the apocalypse, their coverage extended to as many as a hundred thousand universes.
The universe from which the fluctuations came happened to lie at the edge of their coverage. Had it come a little later, it would undoubtedly have been overlooked.
But at this moment, they had sensed it at just the right time.
At the same time, in order to achieve such breadth, they could not maintain that level of range in observational precision. Thus, in a single flicker, they had already arrived at the source of the fluctuations.
Only by getting closer could they obtain sufficiently precise data.
Within the golden flames, the metal sphere began to deform. Almost in an instant, it transformed from a sphere into the form of
