Bringing a Buffet to the Sixties and the Apocalypse

Good news: the young couple Mo Sangyu and Mo Xusheng have both received golden fingers. The former has a Super Buffet System: whenever a customer eats enough to get their money's worth, she gets a chance to draw a prize and win all kinds of great items. The latter can transmigrate through time and space.

Bad news: just as they were about to share the good news, they got into a car accident, and their golden fingers accidentally fused.

Neither good nor bad news: the transmigration ability has been added to the buffet restaurant provided by the System, and the restaurant takes them on random trips through time, to the 1960s, the apocalypse, and other eras and worlds.

Theme: Food is the first necessity of the people.
