After losing her job, Shen Muzhen inherits the enormous debt left behind by her father. Her villa on Huaihai Road has been mortgaged for 200 million yuan, which she must repay in full within six months. With nowhere else to turn, she wipes down the old-fashioned food cart left by her great-great-grandmother and unexpectedly awakens Xiaocan, a little spirit who unlocks the ability to travel between two worlds. Setting up a street stall in a modern city, she uses wild ingredients from the remote mountains to make porridge and flour, becoming an overnight sensation with their extraordinary flavor. In the ancient mountain world, she trades affordable grain, salt, and ironware for prized morel mushrooms, mountain ginseng, and jadeite rough that local villagers consider too bland even to feed chickens. From a roadside stall to supplying high-end private clubs, she uses her ancestral food cart as an anchor to carve out her own success between two worlds.
