The Divine Seal Fragment bound to the Apostle of the Virtual Realm will exhibit slight vibrations to alert the Apostle when encountering other Divine Seal Fragments.
There's only one scenario where the Apostle of the Virtual Realm won't receive such an alert upon encountering another Divine Seal Fragment, and that is when the "other Divine Seal Fragment" has already been pre-bound to another Apostle of the Virtual Realm.
Moreover, the Divine Seal Fragment bound to an Apostle of the Virtual Realm cannot be loaned to others. It's not just because the binding relationship causes the Divine Seal Fragment to automatically return to the hands of the Apostle, but even if others try to hold it, it would seem as if they are attempting to touch a holographic projection, passing right through it. This is the case even if this "other person" is another Apostle of the Virtual Realm. Xuanming once threw his bound Divine Seal Fragment to Xu Gou, and the latter couldn't even catch it.
