Chen Ce time-travels to an ancient famine year, becoming a useless and lazy man in a refugee group. The original owner was lazy, hid food, beat his wife, and finally left his wife and child to wait for death in a dilapidated temple. When Chen Ce wakes up, he activates the check-in system, rewarding him with two steamed white buns. Chen Ce originally thought he could only check in once a day, but when he walked behind the Buddha statue, the system rang again. Checking in behind the Buddha's shadow is successful, rewarding him with a pack of fever-reducing medicine. He climbs up the rafters. Checking in on the rafters of the dilapidated temple is successful, rewarding him with half a catty of dried meat. Chen Ce figures it out: as long as the system acknowledges it as a new location, he can check in repeatedly!
