**Genres**: Urban slice of life / Underworld
**Core inspiration**: Zhang Yi, a former underworld boss just released from prison, only wants to open a small supermarket and live in peace. But his former underlings and old enemies keep “bumping into” him. When he uses a supermarket barcode scanner to take down robbers and the cash register’s algorithms to balance the gang’s books, he realizes his ordinary life has already become a mess of black and white worlds.
