Jiang Ran accepts a system mission to lead three ancients from different dynasties to check in at seven scenic spots within seven days, earning high rewards upon completion. Princess Aman of the Ying clan, Adou, and others are transported to Xi'an in the modern era more than two thousand years later. Faced with elevators, cars, hotels, and other modern things they have never seen before, the ancients are filled with wonder and incomprehension. During their travels, they learn that their dynasties have long since vanished, and the huge gap between eras shocks everyone. While taking care of their food, clothing, housing, and transportation, Jiang Ran brings this group of ancient visitors to witness the rivers, mountains, and myriad phenomena belonging to future generations.
