At three o'clock in the morning, Shen Du received an order. Food delivery address: No. 0 Nanyuan Road - a street that does not exist.
There he went. There are bright lights in a building that shouldn't exist. The front desk is writing code. The people at the workstation are dealing with rules—traffic rules, elevator rules, order reminder rules for takeout platforms. He knows every one of them because he obeys them every day.
Rules don't come suddenly. They seep out bit by bit from mobile phone apps, automatic doors of convenience stores, and traffic lights at intersections.
The scariest thing is - they were there before. It's just that they didn't kill before.
While others were still running for their lives, Shen Du was already reading the first line of the rules.
"There is a loophole in this rule."
