As long as one deliberately searches, it can still be found.
However, on the planes of the Human Clan or the Devil Clan, Transmission Crystal Stones would become very scarce.
Because the Rule Power in the planes of the Human Clan or the Devil Clan is different from that in the Divine World.
Generally, the Demon Realm does not have such Transmission Towers.
If the Demon Realm wants to enter the Human Race World, they would use a very special Transmission Altar, and this Transmission Altar needs to consume the bones of ancient Demon Beasts or Demon Beasts, and even the bones of living creatures from the Demon Realm or their Life Essence Blood can be used to power the Transmission Altar as Transmission Energy.
Obviously, the method of transmission in the Demon Realm is unrelated to the Transmission Crystal Stones.
Normally, Transmission Crystal Stones can be used in the planes where they are allowed to exist.
