Pulling the Thread of Death

Life is actually a countdown to the end of life - a countdown to death. Birth is pressing the countdown button to death. Every beat means one second less in life. It's just that everyone's life is long or short, and we can't peek into the length of life, so we can't determine the initial value of the countdown. We can only record the time of life by counting clockwise. We won't know how long life is until the moment when life stops. Xu Xuehai believes in this philosophical saying and always reminds himself that time is short and he should cherish it more. But he never thought that one day he would personally see the real values ​​related to life. This value is not the remaining time of life, but another aspect related to life, related to the end of life... Mortality rate. Moreover, this mortality rate is not obtained through scientific research. It is on the top of everyone's head, intuitively displayed in the eyes, and everyone in the world has it. And this is the world he sees after traveling through time.
