At that moment, Elsa was right there, fully engrossed in analyzing the spatial traces left in the area. Not long ago, a space passage had been constructed here, but before it could be fully established, it had vanished. The incomplete creation of the space passage, however, gave Elsa an opportunity.
Elsa harnessed the power of Ghost Spirits, the greatest energy within her at that time, to greatly amplify the traces left behind. Gradually, Elsa finally discovered an extremely hidden energy trace. And this energy trace was leading straight underground!
No wonder!
No wonder the Core Clan had tracked their way here only to end up without any result. From the look of that energy trace, it was completely disguised as an ordinary energy conduit, rather than a space channel. However, in the face of Elsa's powerful energy amplification, it ultimately revealed its true purpose.
It led underground?
