It's the second day in a row that he's fought an enemy using flames, but this time he feels completely different. He's worried that she's going to use a knee or a head to hit him, and he wonders if it's because she keeps using "dirty tricks" . He also wonders if they're even physically stronger than each other, since their bodies haven't been "refined by heavenly energy" , which means that they can't use their bodies to hit each other directly. He feels sorry for his sister, who just gave him a big hug and slapped him in the face. She's stronger than ever, he says, and she'll get even stronger after she gets "forged many times . . forging iron ! .
