Madam Wu

Madam Wu is a member of Chivalry Hall and the childhood friend of its fifth leader.

Background
Madam Wu is the childhood friend of the fifth leader of Chivalry Hall, who is Bai Ning's grandfather. After he became the leader of Chivalry Hall, Madam Wu also became a high ranking member of the gang. 30 years ago, she started to abuse drugs and didn't get much sleep, causing her to age faster than she should, eventually reaching the point where she looks like she's in her 80s when in reality she's only 50 years old.

Personality
Madam Wu hates being called old. According to one of her subordinates, anyone who calls her by an age group higher than "aunty" must be chopped to death. This resulted in Ye Yan and Li Lingbiao being chased down by her and her subordinates after calling her "grandma", believing her to be in her 70s or 80s.

Madam Wu likes young boys, as evident when Ye Yan and Li Lingbiao were trying to find a way to become members of one of the "Tyrant Trio" in Dong Guan, and the latter's friend managed to find a way through Madam Wu, claiming she likes young boys, especially high schoolers. If they manage to make her grow fond of them, she will take them everywhere she goes, effectively making them a member of the Chivalry Hall.

Appearance
In her real appearance, Madam Wu is an old woman with white hair tied in a hair knot on her head, wrinkly skin and a mole on her cheek. She also wore a red robe and has a blue tattoo of roses on her left shoulder.

Under the effects of the Youth Pill provided by Cang Ri, Madam Wu regained her appearance from when she was in her 20s, turning her hair long and black, her skin smoother and her body more voluptuous. The mole on her chin also disappears.

Abilities and Powers
Madam Wu has not been shown to have any fighting prowess, martial arts or supernatural ability. However, she was shown charging at Tianran Fei when Bai Ning ordered her and two other men under the effects of the Strength Pill to do so. She was also seen using a knife to hold Tianran Fei hostage so Hong Hong can admit defeat.
