The master of the family is not allowed in the secret room. He tells the young master that he will tell him the higher level of martial arts he needs to pass through. The young master tells his father that he came to see if he could find some books to help him improve his martial arts. The father tells him not to touch anything in the room. The old man tells him that his grandfather left a marrow elixir for martial artists that was half-finished with side effects. The elder man says that he destroyed the elixir before he died because it was a "half-finished product" with too many side effects
