An ordinary office worker - Lin Yun, who was struggling in the pile of reports, accidentally touched the taboo of time standing still. Ability comes with a price - every time it is used, silver marks are carved on the temples, and it attracts the attention of the God of Time. When he made a desperate move to protect his family, he opened the door to the world of martial arts. From the modern workplace to the Qingyun Mountain Gate, from data analysis to internal strength cultivation, he must survive in this arena of swords and swords for seventy-two hours, uncover the truth behind the power of time, and find his way back - or, on this martial arts road marked by time, walk out of his own eternity.
