When considering the pure effects, a 3D communicator has many shortcomings compared to electronic communication, but the advantages are also quite significant.
One is 3D projection.
This is a true 3D projection, with a realism close to one hundred percent.
Everyone saw it.
Besides, technical superiority brings about penetration power; electronic communication relies on satellites and signal base stations for transmission, while spatial communication is a direct link between devices, so there is no issue with signal strength.
Moreover, spatial communication possesses perfect penetration power; even in high altitudes, underground, or under seawater, the link will not be affected at all.
"Is this for real?"
"Is there such incredible technology? No wonder God Zhao personally took the stage to explain it!"
"This technology is invincible!"
"…"
On the stage.
