The early morning sun shone on the school playground, and Mi Xiaoquan came to the school with an obvious red envelope.He reluctantly told his friends that he had bumped into it while having a nightmare last night.However, what surprised them even more was that Xu Doudou had recently become obsessed with aliens and was looking for his classmates every day to verify whether they were from aliens.Mi Xiaoquan and the other three couldn't help but feel frightened when they saw this scene, for fear that they would become Xu Doudou's next research target.

Just when Mi Xiaoquan wanted to take leave to avoid the turmoil, Xu Doudou seemed to have discovered them.Mi Xiaoquan suddenly felt as if he had been exposed and wanted to run away.However, Xu Doudou had already walked up to them and grabbed Mi Xiaoquan's red scarf.In desperation, Mi Xiaoquan came up with a quick idea and said that Tietou and Jiang Xiaoya were people from aliens.In order to escape Xu Doudou's entanglement, Tietou and Jiang Xiaoya would rather bump into each other and be knocked unconscious than be caught by Xu Doudou.

In class, the teacher mentioned the existence of aliens in order to enrich the children's imagination.This aroused Xu Doudou's enthusiasm even more.She put up posters about aliens everywhere in the class, and even went to make trouble with her classmates after class.Mi Xiaoquan couldn't stand it anymore and decided to talk to Xu Doudou.He told Xu Doudou that the squad leader knew where aliens lived.As a result, the squad leader and Mi Xiaoquan started an extreme tug-of-war, trying to get Xu Doudou to regain his sanity.

However, Xu Doudou's energy was extremely high, which made Mi Xiaoquan and the squad leader feel physically and mentally exhausted.One day, Xu Doudou noticed that her pencil was moving while she was doing her homework. She immediately thought that this might be the aliens around her causing trouble.The whole class was avoiding Xu Doudou. Only class monitor Li Li tried to understand her thoughts.Li Li asked Xu Doudou why he wanted to see aliens, but Xu Doudou said that he had encountered aliens when he was a child and even boarded an alien spacecraft.The alien told her to pass on her love to the most promising person next to her.

This story makes everyone feel a bit bizarre and does not seem to be consistent with the real world.In order to let Xu Doudou return to the real world, the friends found the truth of the year.They told Xu Doudou that she was found by the police when she was lost, so the alien was actually the police.Xu Doudou found it difficult to accept this fact and became emotional.

At this time, Teacher Muscle felt inferior because of being tanned during the holidays.He used ultraviolet light all day long to whiten his skin, which resulted in a black and white face.After Xu Doudou saw Teacher Muscle, he felt like he was the alien he was looking for.She chased out, but Teacher Muscle accidentally triggered the power supply to avoid Xu Doudou, causing a fire.
