Zhao Jin, a graduate student in the Department of History, traveled through time and became a princess. On her wedding night, she took out a grenade and blew up an enemy camp in Xiliang. Just when she thought she could use modern technology to crush ancient times, the time travel records saved in the old mobile phone in the dormitory were subcontracted, and overnight she became a suspect of collaboration with the enemy and treason. Murong Lie, the commander-in-chief of Xiliang, imprisoned her on the surface, but secretly helped her track down loopholes in the evidence chain. When Ayina, the princess of the grassland tribe, handed over the secret letter, and when the armorer Huo Qiu showed the copied drawings, Zhao Jin discovered that the bombing of the camp was just the beginning, and the real war was between her and the rules of the entire era.
