I am the Holy Maiden of Miaojiang. To protect my two vulnerable niece and nephew, I take the place of my twin sister, Gu Wanzhou, who is on the brink of death, and return to the Gu family. Facing an adulterous husband who shamelessly lives off his wife while throwing his weight around, a cruel mother-in-law, and a scheming mistress, I unleash my full power and fight violence with violence. I reclaim control of the household and punish the villains who bullied Niannian and Aye. Meanwhile, I use a black snake from Miaojiang to draw out the poison and cure my sister, who has been poisoned for a long time. At the birthday banquet where Madam Zhou tries to slander me by using a fake Taoist priest to perform an exorcism, I make a spectacular entrance alongside my sister, who has recovered from her serious illness, and shatter their conspiracy. I force the scoundrel to divorce me in front of everyone, drive out the wicked mother and daughter, and join hands with my sister to protect the Gu family.
