Ancient female general Su Xiyue accidentally time-traveled to modern Hengdian, relying on real battlefield experience to work as an extra in the crew to make money, using her personal jade pendant to shuttle between two realms, bringing modern supplies back to the ancient Baiyun City besieged by barbarians for emergency rescue. While quickly making a name for herself in the entertainment industry with hardcore "acting skills", she armed the ancient army with modern resources, saw through the Great Xia Dynasty's conspiracy to abandon the city, established herself as emperor, and eventually unified the world.
