Turning Back Time, I Can Go Back Infinitely

A modern, prosperous and ordinary city with an unremarkable surface. The power of time is hidden underground. Time and space changed many years ago, and "time energy" was released. -Ordinary people: Know nothing and will only encounter all kinds of bad luck, accidents, and regrets. ​ -Awakened ones: Infused with time energy and possessing time-type abilities, they are collectively referred to as time-tracing people. ​ -Time Monster: The Regret Beast, which makes a living by devouring human regrets, remorse, and pain, causing car accidents, accidents, family destruction, and career failure. ​ -Time Loop: Time Seam, the birthplace of the Regret Beast. The older and sadder the place, the stronger the Time Seam.
