This chapter takes place on a special day when zhugong is possessed by an "evil spirit gong gong" . The boy asks his grandfather to go play with him in the park. He tells his grandfather that he prefers to read on his own, and that he wants to join in on the fun. When the boy asks if he can play with another player, his grandfather tells him that they can do so without him. He then tells the boy that the stray dog has been hit with the ball and that it looks mad. He warns the boy not to move around at this time, as it will chase away people who have run away. He says that the lump on the dog's head is huge and that the dog must have been on purpose. He also says that if the dog had not acted like it was hit by an invisible wall, the dog would have been killed. He adds that he can see what cannot be seen, like elves and monsters. If the boy does not want to see the elves and other things, he can wear the glasses that come with the meal. The glasses are a gift from a child's meal, so the boy can have the comic. He wants to invent cool things and then heal his eyes.
