A cripple in medieval world

This is the first time I write a novel in English. I’m just a historical nerd wanting to create a beautiful story. It’ll be great if you guys can tell me about my grammatical mistakes ******** This is the story of a modern man reincarnated into a medieval, fictional, and fantasy world. Although he is a cripple, he has some special power that can help him to develop his land and hammer his legend into history. I’m inspired by the legendary tale of Ivar the Boneless. =.= Enjoy!
