The south relay’s copper plate overheated during a new surge. Qinghe received the temperature from its captain and checked the release threshold in the station plan. The mill beside the node had already been cleared, and the crew was sheltering at the school.
She compared the station’s reading with the central gauge. Both showed the plate above its safe limit. Qinghe told the local captain to disconnect it.
Yan held the central line while Qinghe lowered the south feed. At the station, the captain pulled the release cord. The south barrier went dark; the neighboring stations stayed lit as designed. The mill remained unprotected until the plate could be replaced, but workers and nearby families were already in the high shelter.
The captain reported that the cord operated cleanly and no one was near the node. Qinghe marked the time and named the three workers who made the disconnection. The reading arrived late, so she compared it with the station’s written copy before adding it to the central board.
The two records matched after a timestamp correction. The captain had written the bell time instead of the clock time; the crew clarified which bell they meant and initialed the change.
