The luckiest lad

"Ooops, I won again. What can I say? I'm an expert in this field." Riggs merrily boasted as he won another round of mahjong. The three other men laughed along with him despite losing a hefty amount of money.

"You really are a lucky lad." A bearded man with a tobacco clipped in between his lips laughed as he complimented Riggs.

"Hehe, I got my millions back, eh?" Riggs bluntly uttered referring to the million gambling winnings they stole months ago.

"Hehe, young man, sorry about that…" Old man Zhang apologizes again.

[Short flash back]

Six days ago, Riggs came to his office asking for his money. Alas, since he wasn't there and the men who were assigned to guard the office doesn't recognize Riggs, a fight sparked.

Of course, none of them knew what Riggs was capable of and hence, old man Zhang arrived at the specified place with his men tied inside his office; while Riggs sat on his executive chair with his feet resting on the desk.
