1979.
Shen Xuan is the smallest accountant in Kowloon Walled City, and he is also the scapegoat who is pushed out to bear a black debt of 300,000 yuan. The system didn't give him money or fight for him, it just showed him the cracks in the city. While others use guns, he uses abacus; others act as young and Dangerous, but he acts as a trader. When the uncle from the first club knelt down and handed back the warehouse, Xiangjiang saw clearly - this accountant was more ruthless than anyone else.
