This story is about Earth becoming a battleground for the battle between worlds.. again. You thought legends and myths are not real... Well, they are. Those myths were from the battle between worlds, millions of years ago. Many kinds of 'People' from other worlds will be coming. Demons, Angels, Beastmen, Cultivators, Mages, AI(Androids), and more.. ... Hell is the first world to connect with Earth and they are trying to make the people living there their slaves for the upcoming war. Earth has two years to become strong and fight back Hell and the other worlds... Well, it supposed to be two years, when suddenly the other worlders who were trapped in Earth after the war that happened Millions of Years ago started to move. I'll change the synopsis in the future. I'm a newbie so I'll always be reading comments to know if there's something to improve the novel, like if there's a scene that lacks in explanation and is too hard to understand or if there's some scenes that can be added or erased in the story. Also don't mention the grammars anymore, because I will just rewrite it at the future. So don't hold back and start leaving hate comments. Joke, don't hate me please. I posted this story right now because I want other people's opinions to improve the story. I will be remaking this in the future after improving it. I will just focus on writing the story for now, so it doesn't matter if you comment right now or later. It doesn't matter if you read it right now, but please bookmark this book so you can read it and give advice some time later on before I start working on the remake. Thank You...
