In Hong Kong, a mysterious hitman known as the "King of Killers" has murdered a wealthy ex-yakuza crime boss named Tsukamoto.

Fu attempts to enter the building where Tsukamoto's lawyers are discussing the terms of the revenge fund, but is rebuffed by the security.

Martin, the head lawyer in charge of Tsukamoto's revenge fund, makes the discovery that prior to his death, the crime lord was forced to swallow old Chinese wartime promissory notes.

He sells this information to the bounty hunters, and as Eiji is willing to pay the highest amount, he is the first to learn the serial codes on the notes.

Despite their best efforts fighting off multiple Yakuza hitmen and a Caucasian grenade wielding assassin disguised as a priest who Fu kills with his own grenade, Fu and Lo are unable to extract Leung, who suffers a heart attack and dies during their escape and is then shot in the head by Eiji.

Taking pity on him, Lo told Leung to hold onto the notes and, in the event of the murder of the Japanese man he wanted dead, cash them in and forward the money to his bank account.
