In the near future, there is a closed continent called the Void Continent. The Void Continent is surrounded by poisonous fog, and almost no one has been to places outside the continent. Due to the shrinkage of land and resources, Xulu had to divide the land residents into different levels as a basis for dividing residential areas and allocating survival resources.
The basis for classification is appearance. Appearance is the highest measure of human worth. Here, beauty is not a choice, beauty is the law of survival. The highest authority in the Void Continent is the Appearance Censorship Center, which uses complex and accurate artificial intelligence to conduct annual appearance evaluations on land residents. Unqualified land residents will become organ donors, that is, die.
Lu Youyou, an orphan girl with an appearance evaluation of only 5.1, Encounters true love, grows up on her own while struggling to survive, and saves the crisis of Xulu together with three other girls with different personalities and backgrounds.
