This is the first time we've seen Mr. Wu fight, and he's totally freaking out. He's got a ton of power, and it's not just his punching that's killing him. It's his hand, which is shaking with the weight of his punches. He doesn't even know how to move his hand. He can't figure out why this guy's so powerful, because his hand is so weak. He thinks maybe this guy has already broken through to the higher levels of the kaifarian realm, and now he just needs to pay attention to him. The host comes in and congratulates him on his first victory. He gives him 80 points of his own cultivation value for doing so, and the kid is all, "I earned this . . I'm dead" . Uh-oh.
