Quote context

[...]

- Why are you hiding? You admit you're beaten? Come out!

- I'm waiting.

- Look... What are those clothes? Are they yours?

- This is a special technique. It's Ninjitsu. When it's mastered, it's real hard to beat.

- Just now, I was just playing. I mean, if I had been serious then you'd be dead now.

- If I'd have put poison in it too, then you'd have died.

- These techniques, the Chinese have them?

- Sure, but a different name. In Chinese we call it... murder.

- You're trying to insult me, and nothing else.

- No I'm not. I tell the truth.
