When her sister Ye Zhao was dying of "unexplained liver failure", Lin Yin discovered that her symptoms were exactly the same as when her father died ten years ago. A pocket watch that can travel back in time takes him back to the 60 days before his father was killed, revealing the truth about the murderer Xie Jinhao using Eupatorium adenophorum toxin to kill people slowly. But every time the past is changed, the death of the sister in the main world will be accelerated. Lin Yin must find an antidote in the parallel world, while racing against time to seek justice for two generations. Medical suspense × parallel world, a life and death rescue across time and space.
Intention: Some truths need to be revealed across time and space; some protections can only be achieved by breaking the cycle.
