Ling Xiao, a graduate student in the Department of History, accidentally traveled to the Sand Dune Palace in 210 BC during a field trip, just as Qin Shihuang Yingzheng was on his deathbed.
Being regarded as an assassin, he opened the door of two thousand years of time and space with the words "descendants of future generations, come especially to see His Majesty the First Emperor."
Facing this dying but still powerful emperor, Ling Xiao was forced to tell the cruel truth about "the death of his second generation". Amidst the anger and sorrow of the First Emperor, he used panoramic images to show today's China - the magnificent mountains and rivers covering 9.6 Million square kilometers, the thousands of miles of high-speed railways, and the Great Steel Wall of stars and seas.
But the emperor who created great unification was not satisfied with the display of artifacts. He asked sternly: In a peaceful and prosperous age, are your bones still strong? Is your spine still straight?
As a result, Ling Xiao took him to see the Ice Sculpture Company preferring death to retreat, the diplomatic team making a splash, and the younger generation marching against the fire scene with their flesh and blood—generation after generation responded with their lives.
When the First Emperor finally passed away in relief, Ling Xiao returned to modern times, only to find that there was another hidden meaning in this time travel. And on his shoulders, there is already a heavy entrustment: watch the mountains and rivers for me.
