Sister by the Dongjiang River

Cao Yang went to G city to join his sister Li Yan, but he clashed with the security captain because he refused to pay "regular money". He misunderstood Li Yan's work, reconciled and opened a shop to start a business, dealing with gangs. He became famous for his black boxing, and helped Lei Yu regain his goods, offending the Yihe Society. Although he rejected Hu Qing's invitation twice, he laid the foundation for cooperation. At this time, enemies come to the door, and new crises follow one after another.
