After he got out of prison, he went to Shanghai. He quickly got in touch with Fang Yanyun again. But soon he found out that she had changed. She was now the woman of Shanghai's mob boss, Mr. Feng Jingyao, the most powerful man in Shanghai. After Wenqiang got off the train in Shanghai, he unexpectedly saved a pretty lady, Feng Chengcheng. At that time, he didn't know that he would later fall in love with her. Chengcheng was the daughter of Mr. Feng. Mr. Feng helped Wenqiang and his best friend Ding Li become powerful men in Shanghai Bund. Wenqiang was always reluctant to follow Mr. Feng's orders, for he was extremely principled and righteous. Finally, when Wenqiang found out that Mr. Feng was helping the Japanese smuggle drugs into China, he turned against Mr. Feng. As a result, the Japanese wanted to kill Wenqiang because he'd become a danger to them. They waited for him at Fang Yanyun's house.
