A special (you guessed it!) Chinese poison that is administered via injection into your enemy that
slows down their
heart beat, eventually stopping it, resulting in death within (usually) an hour. The effects can only be
postponed through increasing the adrenaline levels. We give this shit to horses, after all.
Chinese shit - "You gotta help me, Doc. I've been poisoned by some kind of Chinese synthetic shit. It feels like I'm slowing down, you know, caught in a
tar pit. Also got that
blurred vision."
