The most important thing is—
There's no worry about network intrusion at all.
The Constant Star Train has no network whatsoever, not even an internal network. In fact, no other trains have it either. The iris chip carries its own information receiver and transmitter, so any command from the Train Assistance AI, as long as it's within the range of the Target Detection Radar, will be received by the information receiver on the iris chip.
This method of information transmission...
is very hard to intercept and invade.
Ai has already gone off to work.
Chen Mang sat alone in the train compartment, picked up a mirror, and carefully examined his own eyeball, attempting to find an iris chip there and see if the panel he could see was also transmitted from the iris chip in his eye.
He could see two types of panels in total.
One is the Train Captain Panel associated with the "Mang" birthmark on his hand.
The other is the panel that already exists in this world.
