Xiao Wugou traveled to the Yu Dynasty and became the fourth prince living in exile.
By mistake, he was arranged by the powerful Prime Minister Wei Wuji to pretend to be the fourth prince and enter the court as the fourth prince.
Xiao Wugou followed his plan and agreed, using Wei Wuji to fight other princes while collecting evidence of Wei Wuji's crimes.
When Wei Wuji discovered that Xiao Wugou was out of control, he reported him in court and exposed him for pretending to be a prince.
Xiao Wugu smiled coldly: "This prince is born with a noble body, why should I pretend to be so?"
