About 2,500 years ago, alien species invaded the Milky Way and killed countless humans. Twelve strong men appeared among humans. They led humans to expel the alien species and set up barriers in the Milky Way to keep out the alien species. After 300 years of forming a federation, humans split into many planets and established a central star. The central star simulated the ancient earth and sent all children to study. Only after graduating from college can they return to the country. One thousand years later, the mythical beast Bai Ze predicted that there would be a great crisis. Bai Ze and the other three mythical beasts opened up a space and placed it in the library of Central College.
Freshman Xia Ci came to the library to gain space after being differentiated and awakening her powers, and worked hand in hand with her lover and friends.
Motto: Only the strong can protect everything that matters
