During the Tianbao period of the prosperous Tang Dynasty, a strange "red mist" swept across Chang'an, turning those who were devoured into bloodthirsty monsters. Su Wanning, the prime minister's legitimate daughter, was reborn three days before the outbreak of the apocalypse and was bound to the "apocalyptic survival system", only to discover that the truth about her tragic death in her previous life was closely related to the emperor Li Xuanxiao. Li Xuanxiao, who is responsible for the "Emperor's Luck System", has already predicted the end of the world, but cannot speak out because of the rules. The two went from suspicion to joining hands. In a desperate situation where zombies besieged the city and powerful officials rebelled, one used technology and system plug-ins to turn the tide, and the other used iron-blooded power to clear the court. When the system mission gradually reveals that this disaster is actually a testing ground for alien civilization, can the emperor and empress reverse the fate of mankind in captivity?
