A city, stitched together by invisible "angles and lines". Takeaway rider Lin Tao follows the mysterious rule of "thirty seconds, second strike" in the gap between daily delivery and pick-up, and collects fragments and master pieces No. 1-24 Among infrastructure facilities such as dams, warehouses, gates, canals, wells, embankments, bridge openings, and stations, gradually approaching a hidden "longitude and latitude base map." Every "second hit" must fall in the memory of the structure, not in himself - making him both the operator and the person being measured.
The first volume revolves around the field trial of "water and weight": the clues start from the suggestion box in the nameless alley and run through the urban waterworks and traffic cavity; the opposing forces approach with "eye-catching signals" (fake maintenance, fake drills), and the black-hatted duo follows and tries to learn the "circle center method". Lin Tao and the leader code-named "Muxiang" counterattacked the opponent based on the principle of "avoiding the center of the circle and taking the offset", and finally closed the first circle with the master film, allowing the "map" of the entire city to emerge, pointing to the sea bridge and offshore wind field. The father-daughter line (Lin Tao and Duoduo) "leave two lights" in the high-pressure mystery in daily temperatures. The next volume will switch to "Wind and Net", starting from the zeroth pile at the south end of the sea bridge, the rules will be upgraded and the territory will be expanded.
