Late at night, a quiet study room in the university library remained brightly lit.
Lin Yuwei sat alone at a long table.
Several notebooks were spread in front of her.
Numbers, arrows, and small supply-chain diagrams filled the pages.
Most students would find the topic boring.
But to her, it was fascinating.
Hangzhou's beverage supply network had changed recently.
Delivery delays.
Distribution shifts.
Certain milk tea shops receiving ingredients earlier than others.
The pattern was subtle.
But it was definitely there.
Lin Yuwei adjusted her glasses and opened her laptop.
She began writing an article on a small business analysis forum.
Title:
"Hidden Changes in Hangzhou's Milk Tea Supply Network."
Her post wasn't long.
But it included several charts showing abnormal distribution patterns.
When she finally posted it online, she stretched slightly.
To most readers, it would just look like a curious market observation.
But to someone familiar with logistics…
The pattern might look very different.
Lin Yuwei closed her laptop and packed her books.
Outside the window, the campus was quiet.
She didn't realize her small article had just attracted the attention of someone very dangerous.
