Conference Room.

Ni Cha and his subordinates stood at the front to give their report.

The director and his bureaucrats, legislators concerned about public safety, and fellow officers of equal rank listened as Ni Cha explained how he used a large dragnet to scoop up big fish from a drained shallow pond.

Precisely 35 years old, meaning the target population was narrowed from over 30 million in Dama to about one million. Then, by examining the number of cross-racial marriages in the previous generation, even considering a small number of illegitimate children, the number of female Chinese and Malay mixed-race individuals with a 6:4 mixture was greatly reduced.

There was also a frequent traveler assessment, which for the police, made airline data incredibly precise—precisely enough for them to want to start filtering suspects immediately upon obtaining it.

In fact, after listening to Ni Cha’s description, several of the officers present began doing their calculations:

"If we’re talking about women who’ve traveled abroad frequently over the past ten years and are 35 this year, there shouldn’t be many, right?"

"How do you define frequent travel? More than twice a year? If someone was seriously injured six years ago, they probably wouldn’t have traveled."

"If we set destination criteria for skiing areas, like Hokkaido in Japan, the number goes down even more."

"That’s tricky to filter. Skiing areas aren’t fixed, and we have to consider transit factors."

"Add in the injury, and we can basically identify the individual. Right, and there’s also the missing persons records."

Hearing their voices rising, Ni Cha simply stopped and let them discuss among themselves.
