Doraemon: Nobita's Space Drift

The people who survived the "Ragnar Mother Planet" and other people drifting in the universe formed the "Galactic Drifting Fleet". In order to find a planet suitable for survival, the "Space Youth Knights" were dispatched to search everywhere. Four people including Li Ang were sent to the solar system and discovered the Earth. They accidentally brought Fat Tiger and Xiaofu who were playing the "Interstellar Voyage" game into their spaceship and left the Earth. In order to rescue them, Doraemon, Nobita, and Shizuka chased them on the "Space Rescue Ship". However, during the space jump, it was hit by a strong electromagnetic wave, causing the spacecraft to be damaged. Fortunately, Li Ang's spaceship also stalled due to a failure of the jumping device at the same place. Doraemon and others entered Li Ang's spaceship and happened to meet Fat Tiger and Xiao Fu. When Li Ang and his party returned to the "Galaxy Drifting Fleet", they found that there was an "Independence Army" headed by Li Ang's father Libert in the original fleet. The purpose of this independent army was to use force to invade planets suitable for survival. They learned about the earth through the sent spy Freya and planned to attack the earth. Under the guidance of the "Yogote Tree", the god of fleets, Li Ang met his mother, and was instructed by her that in order to disintegrate the "Independence Army", he must first defeat Angolmoa, who controlled his father, Commander Libert. With the help of Doraemon, Nobita and others, the crisis was successfully rescued.
