[No system + childhood + super brain + theater version] Nobita, who was scolded by his father, once again had a whim to create a world without adults. As a 22nd century child-rearing robot, Doraemon originally thought that it would just let Nobita experience the hard work of adults, but he did not expect that after using the "if phone booth", the outside world completely changed. Without the inventions of adults, the four-dimensional pocket on Doraemon's belly turned into an ordinary cloth pocket. The time machine hidden in the drawer has also disappeared. Even the "if phone booth" has become an ordinary phone booth and no longer has the function of searching for parallel worlds. It was only then that Doraemon realized that due to his negligence, there was no one over the age of sixteen in the entire world! Just when he was helpless, a person suddenly appeared at the gate, and the first thing the person said when he saw it was: "Hello, Doraemon, my name is Wei Yi, I am 22 years old!" In Doraemon's incredible eyes, an exciting adventure suddenly begins... Ps: The male protagonist has no system and creates his own plot for the theatrical version. The author himself has a very big imagination and will try his best to write the plot for the theatrical version by himself!
