Zhao Heng, a graduate student in the Department of Modern History, suffered a soul piercing accident. When he woke up, he found himself in the Zichen Palace in Bianjing, Northern Song Dynasty, and became the new emperor of the Song Dynasty. Just as he was trying to control this huge empire with his understanding of history, he was horrified to find that the world had already deviated from the familiar trajectory - invisible "rules" shrouded the government and the public, and penetrated into the streets and streets.
"You are not allowed to stay on the street for more than one stick of incense after dark" "You are not allowed to look directly at the 'palace people' in the shadow of the palace wall" "Silk cloth with a specific pattern must be enshrined in the Imperial Ancestral Temple on the third day of every month"... These strange rules are like a hanging sword. No one knows its origin, but everyone knows the price of violating it: at least encountering unexplainable bad luck, at worst, the body changes, and becomes a "walking corpse" that loses its mind and bites strangers.
As the emperor, Zhao Heng not only had to move step by step in the deep palace gardens, keeping in mind all the taboos related to himself and the survival of the royal family, but he also had to face the panic and collapse of order caused by the increasing number of "walking corpses" outside the palace. At the same time, Liao and Xixia in the north were eyeing the Song Dynasty, taking advantage of the internal troubles of the Song Dynasty and frequently knocking on the door, intending to plunder the survival resources that became increasingly scarce due to the changes in rules.
On the dragon's throne, there are strange stories about rules that are startling step by step; thousands of miles across the country, there is the shadow of the apocalypse where zombies are rampant and the existential crisis surrounded by foreign enemies. Zhao Heng must find a balance between adhering to the rules and breaking the shackles, using the wisdom of the modern soul to fight against strange forces, while curbing the spread of national alienation, while strategizing to resist foreign aggression, in this familiar but unfamiliar late Northern Song Dynasty, to find a path of survival belonging to the emperor.
