Li Feng was reincarnated as a Ma Zai in the Kowloon City Walled City in 1971. He relied on the gangster system to gain reputation by working as a branch line. On the surface, he forcibly collected tea money for Guang Zai, but secretly stared at the lame man slumped in a wicker chair. After counting the bills handed over by the owner of the donut shop, he rubbed the oil stars between his fingers and said, "Inspector Lei is going to enter the city tonight, and I have to sweep the road clean before he steps on dog poop."
