Entropy Against Time

In the near future, a technology called "Time Backtracking" allows people to go back in time and rewrite their deaths, and is tightly monopolized by the "Time Backtracking Group". In order to save his wife and daughter who died in a bizarre accident, police detective Chen Mo signed a contract and became a "retrospector" who traveled through time. But as the mission progresses, he discovers that every change in destiny is harvesting a terrifying energy called "reverse time entropy" for the group. And a "Great Retrospective" plan that will cover all mankind and erase all free will is quietly approaching. When his obsession to save his family becomes the enemy of the freedom of all mankind, he must make the final choice at the end of time.
