- My son, it was your fathers who cut off both of his hands.

- Now you've learned kung fu, I shall set you free, if you beat him.

- And I promise, I will not interfere.

- Because of that, you mustn't kill them. But instead, you must try to cripple them.

- Right.

- All right, now start to untie them.

- Right.

- Untie them now.

- The Tigers of Tien Nan crippled my son. And the revenge, I've done the same to their sons.

- And even if my poor son has lost both of his hands, he's very good at kung fu. He's a born martial artist.

- Even crippled, he's a great deal better than most men. A lot better.
