On one side is the peak of industrial civilization in 2024, and on the other side is the darkest moment of Turkic oppression in the first year of Zhenguan. Su Yun, a graduate student in the Department of History, unexpectedly obtained an ancient jade passed down from his family, which set him on a journey to and from the two worlds.
With three shuttle opportunities per month, a maximum weight of fifty kilograms, and the fatal "time and space stiffness" and mental load after traveling, Su Yun walks a tightrope on the edge of life and death. He used modern excess production capacity to fill the national power deficit of the Tang Dynasty, used the historical database from an omniscient perspective to solve natural and man-made disasters, and counterattacked all the way from Chang'an to becoming the "emperor" that Li Shimin secretly relied on.
When modern business logic collided with the power struggle of the Tang Dynasty, and when industrial civilization reduced dimensionality and attacked feudal imperial power, Su Yun took charge of the national destiny and reshaped the prosperous age in the closed loop of the two realms.
