Xun Xing considers himself a peaceful and ordinary citizen, he has no big ambitions, he just wants to live a good life! But suddenly one day an alien group appeared in front of her and told her that she did not belong to the earth or the plane of the Milky Way. She should have belonged to another higher-level extragalactic galaxy 20 billion light-years away, and told her to return to her original position. Thinking that she was a common citizen who had no big ambitions, she refused, but after the alien Tuanzi repeatedly begged (actually it was coercion and inducement, and she could not make other people's ambitions destroy her own prestige), she agreed to go to that galaxy to experience it for a while before making a decision, and thus began a special alien journey.
