Chu Feng transmigrates to the world of Hong Kong crime dramas in the 1980s and becomes an undercover agent in Hung Hing. After five years of ups and downs, he activates the “Disability and Determination System.” From the start, he brings Bad-Eye Ke under his control and makes 500,000 a day selling White Camel Mountain Bone-Strengthening Powder. He only wants to make money to support his injured brothers, but in Kowloon Walled City he meets Gang Sheng, a mysterious black-market doctor. She turns out to be a saintess of Medicine King Valley, banished to the mortal realm and skilled at treating the bloody wounds of the criminal underworld. By day, Chu Feng sweeps through Causeway Bay with four White Camel girls. By night, the celestial doctor clings to him to “test medicine and cultivate together.” When Chan Ho-nam joins forces with Duan Shui Liu and comes after them, Gang Sheng seals their pressure points with silver needles, her icy gaze sharp as frost. “You dare touch my man? I’ll cripple your martial arts first!”
