You have a very rich imagination, @ricardo993! I would love to enter this world you built for this story and have a look around. I sort of saw it as futuristic, yet also kind of medieval.

One of the first sentences in the story kind of threw me off. You might want to have a look at this one to see if you could simplify it or break it into two sentences, so the opening of your story is a bit more readable.

The death of his father at the hands of a god of death still haunted his mind, although it had happened 14 years ago or that time he was locked up for a year in another universe and almost killed his brother, his counterpart from another universe, 11 years had passed since then.
