[Rules] + [System] Lin Mo, a social worker, was accidentally bound to a mysterious system after working overtime continuously. From then on, the world in his eyes was covered by the "rules perspective": the "saving slogan" of the water dispenser conflicts with the heating switch, the boss buttons the wrong suit buttons, and even the street billboards move on their own - every contradiction flashes a mark that can be complained about. The "groove points" accumulated by complaining allow him to leverage the rules, and the introduction is powerless.
