Comic Book's Extras from One Hundred Years Later

Nobita feels that the magazine "Corocoro Comic" is very boring, so Doraemon goes to the future to get back the magazine from the future, especially the contents in the appendix are extremely colorful. But Suneo is very surprised when he sees that Nobita is playing the changing game in the book, so he tells others. They turn out to be terrified by the images from the slide projector. Nobita asks them to play a Japan travel game. As a result, halfway through the game, when everyone is still playing around Japan, Sewashi comes back and takes away the magazine, so they can't come back now. After Sewashi leaves, Shizuka thinks curiously: "Suddenly disappeared, who can it be?" Nobita's mother asks Nobita to eat, but no one responded. In the end, she sees Shizuka in Nobita's room, but Shizuka says that Nobita and the others "Travelling all over Japan" and says "They won't be back for the time being." This makes Nobita's mother puzzled.
