The leader of the Old Rum Gang was succeeded by Big Langmu over a decade ago—he was the eldest son of Old Langmu.
However, because Big Langmu had suffered from brain damage due to a fever in his youth, the Old Rum Gang was still run by Old Langmu and his younger son, Little Langmu.
When the battered subordinate, with two broken fingers, led Lu Li to the second-floor bedroom, Old Langmu was nestled in a blanket by the fireplace, enjoying a leg massage from his younger son.
"So the commotion downstairs was your doing?" Old Langmu, with a pipe in his mouth, squinted his eyes and, through the swirling smoke, observed Lu Li and the bruised and swollen-faced minion in front of the door.
"Senior Investigator Lu Li."
Lu Li took out a Three-Eyed Black Crow Badge, which Old Langmu should recognize.
