The third poison was made more like traditional poison in that although made of qi, it didn't target the qi at all. Rather, it targeted the body.
This poison was for killing. When it entered the body, it would go through it, destroying and disabling important bodily functions until it killed the opponent or was expelled.
But since it didn't target qi, it was also the weakest despite being the deadliest. But when used in conjunction with the rest, no one could stand a chance.
His strategy at the moment was to first use the perception-based poison, disabling the opponent's perception. Next would be the qi paralysis, disabling their qi and leaving them vulnerable.
With no access to qi and the perception needed to detect the final poison, they would just be sheep waiting to be slaughtered. The poison would go through them and they would have no way to stop it.
