Impressive for what appeared to be a human. Piccolo's own healing ability was much the same, or faster if he poured ki into it. That made it impressive to see it on a human. Then again, Piccolo didn't know what the kid was exactly. He could have only been human-like in appearance. Far be it for him to deny the fact that some species were very similar to humans on the outside but less so on the inside. Or for other reasons weren't human at all either.

Piccolo nodded once more to show he heard. "Good. That was quick." A beat. "You ready for what's next?" Whatever that may be.
