In an ancient city in the southwest, surrounded by mountains and rivers, there is a strange legend about the "last bus of the Seventh Route": this bus only leaves at midnight, and its route runs through the old and new districts of the city, connecting strangers with the "Yin Pier". It is said that it can carry away the souls wandering on the edge of life and death, and can also take strangers who stray into unknown foreign lands. The driver and conductor driving this train, passed down from generation to generation, have a special mission to maintain the fragile balance on the Yin and Yang Road.
