I'm Really a Genius

[I know Qing Gong: I buried a bamboo raft under the water, put my toes into the water, and stepped on the bamboo raft to fly. People who didn't know the truth saw it and thought I could possess Qing Gong, so I really did possess Qing Gong. [My external skills are invincible: I hid a hard plate under my clothes and hired someone to hit me with a sledgehammer. I remained motionless. The observers thought that I had developed powerful external skills, so my external skills reached perfection. [I am a genius: I practice while others are practicing, and I practice secretly while others are sleeping. Everyone thinks that I can keep up with the progress without practicing every day. I am a genius among geniuses, so I really became a genius.
