Ning Che's reasoning abilities are top-notch; give her a start, and she can deduce the rest on her own.
"I thought of that point too."
"So, our search area has significantly narrowed down," Qiu Yuluo said:
"Check who died that year; there must be clues to find. If it didn't involve death, those five wouldn't have fled in panic."
"I agree," Ning Che said:
"If the victim didn't die, they would surely have chosen to report to the police afterward. Those five wouldn't have been able to evade the law for so many years."
"It's not just that simple," Lin Yi said:
"Thirty years ago, China was quite chaotic, and the legal systems were incomplete. If someone disappeared, it was highly likely to be left unresolved, which is more secretive than killing somebody."
"Right, right, right, you're hitting the nail on the head," Ning Che said:
"Look into the missing persons at that time; finding clues from this angle might just pay off."
