Humans do not gain eternal life. They just learned how to distribute death. Since the life-extending substances on the moon were extracted industrially, human society has entered the "era of adjustable lifespan." Telomeres are no longer a biological concept, but a measurable, transferable, and settleable resource. For a few people, life has been extended indefinitely; for more people, lifespan has become a quota - based on working hours, job level and risk tolerance, ensuring that every day of survival has economic significance. The moon is therefore no longer just a celestial body. It is the production line, the buffer zone, the place where ethics are placed out of sight of the earth. Lunar workers in low-level positions are rewarded with "living one more day" and maintain the operation of the entire life extension system. The protagonist is a graduate-level scientific researcher working on the moon, responsible for maintaining the most inconspicuous and least-attended parameters of this system. He did not rebel against the system, nor did he intend to change the world - until one day, during a routine calibration, he discovered that there were unexplainable abnormalities in the flow of life quotas. At that moment, he realized for the first time that the reason why he was still alive might not be because of luck.
Purpose: By describing a future society in which life span is institutionalized, we explore how the value of individual life is redefined under the intersection of technological progress and class solidification, and reveal the ethical dilemmas and social injustices behind the life extension civilization.
