Hu Jialin, the daughter of the former gangster boss, was hospitalized after being attacked by Han Lang, the second in command. Wei Junxuan, a former police officer who was a member of Shenglian, has been guarding Jialin, taking care of Jialin and apologizing to her. After Jialin was discharged from the hospital, she finally accepted Junxuan and the two got married. Han Lang supported Junxuan to become the boss of Shenglian, but he still controlled Junxuan from behind. Junxuan was assassinated just after he took office. Han Lang left Junxuan to take care of Shenglian, and went to Thailand alone to open up all the drug trafficking routes in China and Hong Kong, but was ambushed and captured by his enemies in Thailand. Unexpectedly, he met Zidan who was captured in Thailand in the cell. Zidan wanted to kill Han Lang, but couldn't do it because of his sense of justice. When the two were imprisoned and at a loss, they were rescued by a mysterious person. This mysterious person turned out to be Zidan's girlfriend Chen Yueqi! It turns out that when Zidan and Yueqi were in crisis and were about to be executed, Luo Wei did not kill Yueqi, but hid Yueqi and waited for an opportunity to reunite Zidan and Yueqi. Yueqi learned that Zidan was kidnapped to Thailand and came to rescue him regardless of everything. Zidan was determined to paralyze Han Lang and proposed to reconcile with Han Lang. The two worked together to reorganize the Thai underworld forces and returned to Hong Kong.
