Su Yuqing is a low-level holographic visual effects rendering artist in the modern world. She works overtime until late every night and is constantly tormented by demanding, status-conscious clients. After an exhausting forty-hour continuous work session, she accidentally misses a step and falls into a rift in space-time, gaining the ability to travel freely between the modern world and a high-martial-arts Great Qin plagued by rampaging demonic beasts. At this moment, Great Qin's frontier is facing a devastating assault by countless charging beasts. The Great Wall defenses are on the verge of collapse, and the young divine general Bai Qi, who has been holding the border fortress to the bitter end, is preparing to perish alongside the city.
