Lin Xiaoyu got into a car accident and came to the universe, but entered an alien planet and saw a huge and hairy alien. When he came here, Lin Xiaoyu was undoubtedly an alien.
Lin Xiaoyu first met Shen Ya, who had been to the earth, and later met alien policeman Lin Huai. Lin Huai captured Lin Xiaoyu and used her as a guinea pig for experiments. Lin Xiaoyu successfully escaped with the help of the biological prisoner Xiaobai and went to Shen Ya.
With the help of Shen Ya, Lin Xiaoyu took a fantasy journey in the alien world and met his favorite alien lover.
The arrival of Lin Xiaoyu changed the aliens and the people on earth, and the people of the two worlds coexisted in friendship and peace.
