The Space Time Tunnel is a passage leading to the Boundless Chaotic Sea. Before the threats on the Saint Origin Continent are completely resolved, Ying Yue will not reveal the location of the Space Time Tunnel to anyone.
Think about it, if the Space Time Tunnel were exposed and a group of Saint Kings rushed into the Boundless Chaotic Sea, what kind of massive slaughter would ensue?
Ying Yue considers himself unafraid of any individual Saint King, but facing an onslaught of a group of them makes him uncertain. Moreover, the Boundless Chaotic Sea is so vast that any Saint Sovereign or Saint King entering it would cause significant trouble!
Therefore, not exposing the existence of the Space Time Tunnel is the wisest course of action at the moment!
