The Sword Tower Realm was one of the most famous independent realms, and the main reason behind this was that they had inherited one of the Four Great Sword Doctrines. It was the Eternal Sword Doctrine! If one practiced with his sword while using such a doctrine and comprehended how to form a Sword Spirit, then the Sword Soul or Sword Domain created by using it would be extremely terrifying.
