Ten years ago, Yokohama Dadong President Dachang (played by Chaoxio Ueda) made a separation plan, which led to constant disputes between the Xiabincun group and the Hong Kong North Society, and the big market reaped profits. Bincun group leader was killed in the struggle, Bincun group member county Yifu (Heda Haoer) also shot the leader of Gangbei group. The sheriff was convicted for 10 years. After getting out of prison, the sheriff tried every means to find the hidden Dadonghui, extorted 5 million yen, and then summoned the old department to march on Okinawa. The Naha area of Okinawa is carved up by two leaders: Tomoshi Yamamoto (Linichi Yamamoto) and Nahara (Fusaburo Ruoyama), and there are also a number of rogue organizations under it. Soon after the prefecture department and others came, the great eastern forces who took a fancy to the Okinawa port trade intervened. Bo Zhao had no choice but to bow to the Dadonghui and resolutely fight against the original faction. The sheriff was forced to make peace with Dadong, but it was not so simple.
