Zhang Dabing, a member of the 996 community, received a mysterious invitation that was completely black while working overtime until late at night. He thought it was a prank game, but he didn't expect that the invitation was the only certificate leading to a time and space tunnel. From then on, he was passively involved in bizarre tasks. In a strange time and space, he must fight for survival and fight for rewards. When traveling through time and space becomes a job, and when life-threatening adventures become the norm, the social beast who once only wanted to fish has to take up arms and become a time-traveling wage earner struggling to survive in countless worlds.
