One late night, the last bus on Route 404 carries delivery rider Lin Xiaoqi into the "Abyss," an infinite-instance space that uses living people as test subjects. Others risk their lives to clear each stage; he cheats his way through. The rules say, "Do not speak to the driver," so he passes a note. The rules say, "Bow three times to complete the ceremony," so he turns around and bows to the mountain god. The System patches its rules every day to target him; every day, he exploits bugs to strike back. From Foggy Street to the Happy Residential Complex, from a paper-figure wedding to a midnight radio station... As the Abyss realizes it is becoming more and more like him, it begins to grow afraid. Seventh-generation tester Lin Xiaoqi specializes in putting every challenger in their place, including the Abyss itself.
