"That little fellow actually hid in Kedan for millions of years. Even Shu Zi couldn't find him. It seems he became aware that we were searching for his trace and deliberately hid in the Forgotten Ancient Ruins." Wufu Great Emperor said.
The Forgotten Ancient Ruins, if left behind by an Ancestor Realm, perhaps they could still faintly sense it.
But once entered into a Great Emperor's Forgotten Ancient Ruins, similar to the Profound Dragon Ruins, the beings inside would be completely isolated from the outside, unable to sense the outside world, and the beings within unable to communicate with the outside.
Because this is a forbidden law personally set by a Great Emperor Realm, unless one possesses a deeper mastery of arrays and restrictions, it's utterly impossible to detect where the beings are located.
