With the advent of time entropy, "time" has replaced money and power as the scarcest resource driving conflict.
Conventional medicine and technology have no effect on the countdown.
The deep secret hidden in the world view is that the underground of Class F where Lin Yu is located is the "singularity" where the time entropy of the universe was first leaked. Lin Yu accidentally fused the singularity fragments when he was a baby, becoming the only living blood bag in the world that is immune to time entropy and can produce "time source power".
