After observing for half a day, Shen Shi could only reach a conclusion similar to what the Mude System had suggested. There should be traces of a Relic Civilization behind this technology.
Because this power based on Primordial Energy clearly and vaguely exceeds the current understanding of Primordial Energy in the cosmos, otherwise, even an A-level Civilization wouldn't find it hard to detect even a trace.
It's truly unimaginable how powerful the Relic Civilization must be.
Being powerful to this extent is one thing, but their footprints seem to be scattered throughout the cosmos.
