After integrating her memories, Shen Zhao used his accurate knowledge of the history of the Northern Zhou Dynasty (such as Emperor Yu Wenyong's centralization route, the plague in the last years, and the fight for the crown prince) to first disguise himself as a refugee to hide his identity, and then infiltrated the capital of the Northern Zhou Dynasty as a medical woman. , Gradually weakening the enemy's strength by solving the plague, exposing corrupt officials, alienating the princes, etc., And at the same time establishing an intelligence network with the old Nanliang troops. Finally, after Emperor Wu of the Northern Zhou Dynasty died of illness, he launched a coup in the court, supported the puppet emperor, and restored the Southern Liang Dynasty.
