Lu Chen is an undercover Cang Yan Society policeman, and Jiang Lin is the puppet heir of the Cang Yan Society who has the ability to reset the timeline.
Jiang Lin's pocket watch can reset time under certain conditions, but the price is that every time it is reset, his body will pay a certain price - deafness in his right ear, blindness in his left eye, loss of taste... In the 48th reincarnation, he only had one confession left that he could not pronounce: "I love you."
Purpose: fairness and justice
