Reincarnated as a Swordsman

I got reincarnated after I died at my world and left by my new family at a church. I grew up with a simple life and so-called family with everyone there. My world is surrounded by a formless energy and we call it [Mana]. But we can't directly use it on our body we need to use a 'special things' we call [Armas]. We use those weapons to channel the [Mana] to become a [Magic Attack]. But in order for you to get an [Armas] you must train your body and mind because if your body is weak the [Armas] you contracted will devour your body and overtake it. Then after obtaining an [Armas] you must achieve great victory in every battle to become the most famous and powerful individual that will be known across all four layers of Verdelen. and that is to become... the God of War.
