Age of Ascension: The First

Age of Ascension.  This is a story of a reincarnated person in alternative world. Earth, or what I should call Sector 77 now, was a beautiful blue planet inhabited by humans.  But the blue planet is no more.  The planet's size has expanded ten times, and a powerful magical barrier surrounds us like a cage. To make it even worse, we got trapped in this cage with aggressive alien races that invaded us.  Although we have so many conflicts and hate among ourselves, we didn't expect a higher power to befall us one day. A power that made humans united against a common enemy, the Syluman.  I, Theomars Adam Gates, will thread a path for humanity! ... Hello, This is Nine_Clouds! This story is my first original novel. I'm still experimenting with it, so please give me your support and comments about the story. English is not my first language but I guaranteed that the story is readable.
