I totally get why people are confused, I was at first too, but it's a centipede that's across the master's whole body. It's the Gu poison, poison created by putting a bunch of venomous bugs and put them in a jar, let them fight and eat each other until one is left. The centipede is the Gu poison that was used as a way to bring him back to life... Because as they say, poision is also medicine in certain quantities.
