It tells the story of an ordinary person, Xu Chen, who accidentally gets a mysterious mobile phone that can connect to the ancient times. From then on, he started a fantasy linkage spanning the Qin, Tang, Song, Yuan, Ming, Qing and other dynasties with modern society. When the mobile phone screen reflected the wars of the Qin Dynasty and the prosperity of the Tang Dynasty for the first time, Xu Chen never thought that this small device would become the fulcrum of time and space. He used modern knowledge to help the Qin Dynasty improve irrigation and help the Tang Dynasty prevent and control plagues, but he also accidentally caused ripples in time and space - mysterious forces awakened due to excessive intervention, time and space cracks frequently appeared, and cultural collisions and interest entanglements between different dynasties ensued. From the transformation of military modernization to the establishment of a legal system across time and space, from the beginning of space exploration to the popularization of agricultural science and technology, Xu Chen joined hands with talented people from seven places, including Li Si, Su Wan, and Shen Kuo, to move forward arduously in technology and tradition, intervention and balance, conflict and integration. They cope with information overload and climate change, witness the birth of marriage across time and space, explore the relationship between technology and "magic", and realize in crisis after crisis: it is never mobile phones that connect the past and the present, but mankind's common pursuit of peace, civilization and beauty. When the truth of the mysterious power is revealed, when Xu Chen prepares to say goodbye, and when various dynasties form a new balance of time and space, the mission of this mobile phone is gradually completed. But what it leaves behind is a world of diverse symbiosis - the warriors of the Qin Dynasty can operate energy weapons, the medical women of the Tang Dynasty can use modern instruments to diagnose, and modern children grow up reading the poems of the ancients. The exhibition "Across Time and Space" is still going on. The willows of time and space on the banks of the Yellow River are getting stronger and stronger. The infinite possibilities of the future are slowly unfolding in the light of the intersection of ancient and modern times.
