Records of the Conqueror Book Idea

This book idea is inspired by the novel 'Records of the Human Emperor'. This novel should be extremely slow to describe everyday life, territory development, court intrigues and most importantly huge battles with intricate strategies.

The protagonist is reborn in a mid-level Martial world as the son of the archduke in the northernmost empire on the northern continent (five continents= west, east, north, south, central). This empire is one of the top 3 empires on this continent and is renowned for it's strong army, especially the cavarly. (Optional= He is the fiancee/husband to the eldest princess which can ease the transition from general to emperor). The protagonists start off by joining a high position in the army at a young age and achieving the highest possible position by conquering the northern continent. After the unfortunate passing of the previous emperor, the protagonist now ascends to the throne to conquer the world. Some special additions to this world should be innate Mounts, innate pets, innate weapons and innate armour. Each person should be able to have innate weapons and armour which is self-explanatory. The innate pets are pets bound to the soul until death which are usually not used as mounts because innate mounts are the mounts bound to the soul until the death. The innate mounts gives all soldiers the ability to transform into a cavarly. All of these 4 things can be stored inside the persons soul, can be summoned at any time and heal inside the soul.

Ideas for the protagonist:

-White Owl as the innate pet: It is a good scout and looks noble and badass

-White Shadow Horse: The innate mount with extremely strong body and soul as well as teleporting, shadow and snow/ice control abilities. Looks extremely good and is fitting for a general.
