Modern college student Chun Ya transmigrates to ancient times with her entire family, only to find themselves immediately burdened with debt. Using her modern knowledge, she opens a restaurant called Star-Picking Pavilion, but encounters a mysterious monk named Dao Xuan, who tells her that she must collect the Tiger Essence and Earth Soul to return home. In search of the treasures, the whole family purchases a barren mountain and unexpectedly discovers a spring and sweet potatoes. Locust plagues and epidemics strike one after another, but Chun Ya leads the villagers in fighting the locusts with fire and containing diseases through quarantine, overcoming one crisis after another. To find the other half of the Earth Soul, the family travels all the way to Lingnan, outsmarts a shady inn, and uses saltpeter to make ice and preserve lychees. Finally, they find the treasure in a cold pool deep in the mountains. Their achievements earn them the emperor's favor and rewards. With Star-Picking Pavilion reopening, the whole family reaches the peak of their success, now waiting for the day when the seven stars align to decide whether to stay or leave.
