In the middle of the night, Fang and the others hear the sound of a woman's voice, and Fang realizes that the noise is coming from the inner part of the cave. He decides to go back to the outer part to find out what's going on, but first he has to figure out what Fang is up to. He realizes that Fang is trying to kill him, but he's not going to let Fang die. Fang says that if he dies, Fang will surely die, and he and the other two will stay behind to help Fang. Fang is all, "well, guess we've got to tag along with as well!" . Fang tells the others that they've run out of energy from their invisibility, and they'll have to stop using it if they want to survive. They're surrounded by monsters, so they need to find a way to save the two men. Fang asks about the fox, and the two of them tell him that the fox doesn't seem to care about them at all, and that they can track down the men if they keep running away. Fang wants to know where they're going, so he asks the others to lead the way, but they can't find the inner zone, which is too quiet. They hear a rustle, and then they hear a woman crying, and it sounds like she's about to die.
