In contemporary cities, there are still a large number of "rule fragments" that have not formed complete copies - such as "You cannot look in the mirror at three o'clock in the morning" and "Looking at a stranger's cell phone will see the last three minutes of the deceased's memory." The heroine Su Wan is a "rule recycler" who can capture, dismantle these fragments, and convert them into storable rule currency. But she soon discovered that these fragments were not naturally generated, but "corrupt rules" that someone deliberately fed into the city. The purpose was to activate a "flesh and blood abandoned copy" sleeping in the collective subconscious of the citizens. Once the copy is fully opened, the entire city will be pulled into a horror game. The only solution is: when the copy completely arrives, retrieve the 7 lost emotions and use them to blow up the core of the copy - a "rules engine" built by human negative obsessions.
