Nobi Nobita's Time and Space Adventure

When I wake up, the level of technology has regressed back to sixty years ago. In the small town of Tsukimidai, all the memories of Doraemon have disappeared with the passage of time. After going through some twists and turns, Nobita and his party learned the truth: an unprecedented, large-scale war spanning time and space is taking place, and the target is the future of vigorous development of human science and technology. The dominoes hidden in the past have collapsed and are about to form a huge wave that will engulf every era of mankind. The only clue is a snapshot that also spans time and space. On September 19, 1492, in the center of the vortex of space-time turbulence, the time police took a photo of the back of a blue parenting cat robot. Taking this as an opportunity, Nobita and his party were involved in this huge robbery across time and space. And as they intercepted more and more clues in various eras, a huge conspiracy gradually emerged. This novel and its characters are purely fictitious.
