I Will Be a Border Inspector in the Future, Specializing in Checking Illegal Crossings

In the near future, after the time rift appears, illegal time travel has become the most profitable black industry. Someone stole the lottery numbers from tomorrow. Someone returns to the present with life-saving medicine ten years from now. Someone pretends to be their not-yet-dead self, taking over their identity and rewriting their lives. Shen Yan was just a low-level pass checker at Hailan Time and Space Port, until he picked up the old sampler left by his father and saw the time violation records on everyone. Starting from a lottery ticket from tomorrow, he gradually discovered the truth about future medicine, identity substitution, the black market of time, and the disappearance of his father that year. "Illegal crossing, please accept inspection."
