As a child, Chen Qinian lost his left eye in a radiation gambling game rigged by the top-ranked viewer. From then on, he scraped by in the wasteland's black markets. He discovers that every top-ranked viewer's donation conceals a kill order from the real world. So he disguises himself as a clown streamer put on display for their amusement and sets a trap to take down the top-ranked viewers. The mechanic Bai Jin joins forces with him, carrying fragments of the truth. The information broker Slug provides the top-ranked viewers' password, while the wilderness killer Croweye closes in, hunting him live, step by step. Meanwhile, the settlement leader Su Tie watches him closely, determined to stop him from becoming the next top-ranked viewer. When the first of them, Wei Tu, falls, Chen Qi realizes that all the top-ranked viewers are being controlled remotely by an AI from the old war called the Calculator, and every donation from the audience is speeding up the fall of humanity's last city.
