Gao Zhang, a girl from the Department of Modern History, was reborn as the daughter of a criminal official of the Qin State. She woke up in a ransom cell and rescued her younger brother Gao Chuang who was about to be executed. Relying on her past life memories, she memorized the key evidence that the old aristocrats framed her father. She took the risk to bribe the doctors and petty officials, and asked Qin Shihuang to present a map of the modern territory, which pointed out the hidden dangers of the old tribes in the Six Kingdoms and Zhao Gao's ambitions. Ying Zheng was dubious and left Gao Zhang in Xianyang for further investigation.
