But after giving his heart to the wrong woman, he is dragged into a whirlpool of political intrigue.

On the brink of death, Chen Yan activates the pocket watch passed down through his family. Hidden within is the “Time-Slice Core,” which can preview the next ten seconds. From then on, he embarks on a path of revenge driven by intellect. He uses precise calculations to counter conspiracies and steam-powered mechanisms to set traps and turn the tables, uncovering an even greater betrayal behind Su Wan as the gears turn.
