Supreme Commander General (Remake)

I got reincarnated into another world. I have the ability to create my own army. I can also level them up and upgrade them from one type to another. I am The Supreme Commander General. I will rule the world with this amazing ability. All Hail The Supreme Commander General. This the remake of my other novel. I will be adding kingdom building to this novel as well. I will be fixing all the mistake I did in my other novel. I will be making it longer and with more detail.
