[6] Eight years ago, Liu Ziguang (William Chan) left Jiang Bei City after his father's death.

However Ziguang trained himself and managed to escape, eventually being recruited by Wanfeng to join his syndicate after Colby's death.

After learning of Wanfeng's true and malicious nature, Ziguang tipped the police off on a drug deal in international waters and escaped.

However he hit his head in the waters and after being washed ashore back in China, he had no memory of what transpired in between his self-exile to present day.

He then met policewoman Hu Rong (Ma Sichun), and two worked together to expose Wanfeng's crimes.
