Giving Men to the Shadow
The Shadow, having learned of Ava Simmons’ death decides to hire a new assistant and so he goes to Doãn Ðình Thiện’s nightclub to recruit men. When he gets there Thiện tells him that if he can defeat his four best fighters Lê, Huỳnh, Phạm and Đặng as well as his bodyguard Ngô he will supply him with men and weapons. The Shadow fights with them until he makes Đặng slit Lê’s throat. Then he impales Đặng through the torso with his saber and kicks him backwards into Ngô. Phạm then tries to slice him but is cut down to his knees where the Shadow impales him through the head, then he makes Huỳnh trip by throwing Phạm’s saber at his feet, causing him to impale his head on his saber. Then Ngô tries to attack but gets cut down and then his torso sliced open by the Shadow. After defeating his men Thiện gives him Nguyễn Phúc Sinh as his bodyguard and five of his best men Cao, Châu, Uất, Quách and Úc to him.
