After five years in exile, his eldest daughter Shen Qingci returned to Jinling with her skills in medicine and poison and her heart for revenge. She formed an alliance with Xie Yunlan, who had a family feud, and went through dangerous situations such as setting up a bureau at Jing'an Temple, visiting the Duke's mansion at night to collect evidence, and inciting key witnesses to rebel.
