In this chapter, we learn that a black box has been discovered in the royal tomb of the Ming Emperor, and that it is guarded by a little beast named Little Ball. The little beast asks the master of the tomb to open the box, but the master is unable to do so because he has used up all of his energy. The master tells Little Ball that the box is missing one important factor, which means that something is missing inside the tomb. Little Ball says that he can't take care of the beasts by himself, but he does have a plan. One day, Little Ball's grandpa tells him that someone has discovered the tomb and that a large number of people have gone to the tomb, so Little Ball asks his grandpa to allow him to go. The grandpa agrees, and Little Ball promises to come back when he is done with his mission.
