Ladder Maintenance Worker

In the near future, the "ladder to heaven" at the equatorial base will be the umbilical cord from human civilization to the star sea. The external maintenance personnel of the ladder, this group of "space trackers" walking on the steel cable, are the most unknown guardians of this umbilical cord. Senior maintenance worker Chen Wang suffers from a rare "gravity allergy" and can only get a moment of peace in space. He senses the "breathing" of the ladder with the intuition of his hands, but the gap between him and his son Chen Xing, who believes in data and AI, gradually deepens. When Chen Wang discovered that there was a fatal hidden danger in the core cable of the ladder that could not be identified by AI, his early warning was covered up by the chief designer Lin Mo in the name of the overall situation, and was regarded as alarmist by mainstream public opinion. A sudden disaster caused all high-tech means to fail. In the desperate situation of loss of pressure, radiation and violent swings, Chen Wang used the most primitive method to save the ladder, which also proved that in a place beyond the limits of algorithms, the intuition and touch of human hands are the irreplaceable last line of insurance. This is a heart-warming narrative about a great country's important weapons, the relationship between father and son, and the spirit of craftsmanship.
