In 259 BC in parallel time and space, in Handan City of the Zhao Kingdom, a declining clan girl named Zhao Xuan accidentally traveled through time and became the concubine of Ying Yiren. When Zhao Ji was killed for offending King Zhao and entrusted Ying Zheng to Zhao Xuan before her death, she knew very well the mission she shouldered - to protect this child who might change history in the future. Zhao Xuan relied on the protective shield and summoning ability given by the mysterious "system" to survive the pursuit of Zhao Guo and started her legendary journey.
