The only places possible to acquire Condensed Space Fragments are blackholes. Those are the most dangerous existences in the Universe, and the ones in the Godly Path Realm are even more so. Space and time around it are unpredictable, let alone the gravity pull. Even a Nascent God would be helpless if he fell inside one of those.
A Condensed Space Fragment can be found once a Blackhole's Quasar comes out. During that moment, Space warps so much that some of it condense. Once that happens, one must be fast and take it before the fragments fall inside the Blackhole itself.
As one can imagine, it is extremely dangerous, and even Nascent Gods would probably die if they tried. That's because those fragments appear way too close to the Blackhole itself. The gravitational pull is so intense that the Nascent Gods trying to get the fragments could instead be trapped by the Blackhole and die within.
