The protagonist, Lin Chen, is a delivery boy struggling to make ends meet. While delivering food on a rainy night, his palm was scratched by a mysterious fragment of a bronze pocket watch, and he accidentally awakened to the "time credit knife" function. The story begins at the snow-top ruins of the Kunlun Mountains, where the millennium secret of the "Seal of the God of Time" is hidden. In ancient times, the ancestors of Kunlun used the "Time and Space Stone + Four Vessel Blood Veins" to seal the God of Time who attempted to devour human memories behind a bronze door. Ten years ago, in order to seize the Time and Space Stone and awaken the God of Time, the Time Xu Society caused the two people to "disappear". The Time and Space Stone was broken into two halves, one half was secretly hidden by Elder Kunlun, and the other half fell into the hands of the remnant soul of the God of Time. The Snow Summit ruins have been in danger ever since.
