When she activated the glasses, Su Na's vision went pitch-black, as though she had entered another space. It felt extremely real, without causing her any discomfort.
"...This is some kind of direct brain-computer interface technology, and a very mature version at that. It allows signals to pass freely between the two..."
Su Na made her assessment because she could still feel her body in this dark space, and could even move. Unless she sent a signal to take off the glasses, the illusion would not break. The technology was quite mature, already very close to reality.
"Correct. These holographic glasses do indeed use that technology. They took two years to develop, and I was the project's lead at the time."
Another person's voice rang out, bringing a look of surprise to Su Na's face. Almost instantly, she turned toward the newcomer.
He was a young man wearing glasses, who had suddenly appeared in Su Na's field of vision.
Light shone down from above his head, illuminating his surroundings and revealing his spotless white robe and his eyes, clear and limpid as the finest sapphires.
Perhaps noticing Su Na's confusion, the man continued.
"Don't be surprised. This isn't virtual life technology.
I'm merely a program constructed from data and behavioral logic. The real me should have died long ago."
The newcomer spoke as though he could read minds, guessing roughly what Su Na was thinking from her scant behavior and the look in her eyes.
This was some kind of advanced interactive technology.
Unlike a simple recording, it actually allowed interaction with the objects, and even the people, inside it.
So, for a moment, Su Na had mistaken him for a virtual life-form. In her conjecture, the Duchy should have mastered that technology too, bringing it very close to being a
