The world experienced a great change. The MC is conquering this crazy new world. The time is set, you have 1000 years.         Good Luck!   PS: It will be something like the Korean light novel Dimentional Sovereign, but on a world wide field. (Be aware, some of the ideas will be used but the rest will be original) I don't think that the MC will get too OP. Well if he gets too OP he will get a new enemy to battle with.
