Who could have imagined that a young man would accidentally unlock a dimensional travel system! Jiang Ye, who has only three months left to live, receives a mission to recruit tourists and take them back to ancient times. Completing the mission will earn him extra lifespan and cash rewards. He sets up a stall at the train station, selling thousand-yuan one-day tours to the Qin Dynasty. At first, everyone passing by mocks him, and only five people sign up, willing to take a gamble. Following Jiang Ye, the group witnesses a car appearing out of thin air and travels through a tunnel to truly arrive in the Qian Dynasty. After changing into ancient costumes, they enter the city to witness the emperor's eastern inspection tour. When a tourist accidentally turns on their phone's flash, it attracts the attention of soldiers, who surround and arrest them all. The group ends up locked in prison.
