"Maybe we shouldn't be curious about that..." the Fisherman said weakly. "If it records us too, then we'll never escape for the rest of our lives."
"Immortality sounds pretty good." Sun Hang said in a half-joking tone. "If this were ancient times, you could present this thing to the emperor and surely earn yourself a noble title and a reward."
"Forget it... According to Yano's description, everything recorded gets reset to how it was four years ago. No matter what I've done in those four years, it would all become meaningless. Even my memories would be wiped... Just thinking about it gives me chills."
"Wait." Sun Hang suddenly cut the Fisherman off. "Yano, if someone who was recorded affected something outside the domain during those four years, would those effects remain after that person was 'reset'? For example, if Tumi recorded a woman, and during those four years, the woman went outside the domain and had a child with a man who had never been recorded—when she was 'reset,' would that child vanish from the world too?"
"Uh..." Even Yano was stumped by Sun Hang's question. "The experiment records... don't seem to mention whether they tried anything like that..."
"What about other clues? For instance, after those natives were reset, did the food they ate off the island suddenly reappear in the institute's cafeteria or kitchen? Or the shit they took a few hours before being reset—was it still in the laboratory's sewage pipes? Was none of that recorded at all?"
Yano shook his head in astonishment. "No, no... There's absolutely no record of it."
"That's far too sloppy." Sun Hang criticized them righteously. "Shouldn't documenting the test subjects' diets and excretions have been the most basic part of the job? Didn't they conduct routine urine and stool tests on
