Eight poor boys kowtowed on the iron bridge and sworn sworn vows, agreeing to share in any difficulties. The eldest brother's name is Lu Zheng. After two years in prison, he came out and found that his brothers couldn't even keep a street. He led his men to seize the Blue Ocean Nightclub from the Chengnan Gang and kicked open the gate of the North Street site. The first volume is a group fight for meat. Eight people worked together to seize the venue and the dock from Han Bao, and win every battle. On the day when fireworks were set off on the iron bridge, everyone felt that good times were coming. The second volume is about separation and wine. If there is too much money, how to divide it is a problem. Lu Zheng wanted to clear his name and go ashore, but Chen Mo, the second-in-command, thought he didn't get enough. When the ledgers were spread out on the rooftop, Chen Mo said: "It has been twenty years, you are the boss, and I will always be the second child." He held these words for twenty years, and from that day on, brothers were no longer brothers. The third volume is the bloody battle at the pier. Chen Mo set up his own business and grabbed the Xingang Pier from both sides. The old cat died in the chaos, and Lu Zheng changed - from now on, he only cares about interests, not human feelings. Volume Four is Reckoning. Chen Mo exposed Zhang Lei's old account of embezzling money twenty years ago, and handed Lu Zheng's gray evidence to the police, hoping to use rules to kill people. The two people smoked the last three cigarettes on the iron bridge, and then they dispersed. Lu Zheng personally sent Chen Mo in, and then stood on the bridge alone and said to Ning Jiang, "We will be brothers until death." In the end, the most difficult thing to guard is not the enemy's knife, but the hearts of the people around him.
