Sun Mo thought a lot about it and chose the art of spiritual beast control in the end.
Spiritual beast control actually meant two things but was classified as one subject by the Saint Gate.
One was beast taming, which meant the ability to control beasts and train various kinds of beasts. One would be able to conquer these beasts through various methods and command them to combat.
In simpler terms, it was like how a hunter would raise and train his hunting dog to help him go after prey or even kill them.
Of course, beast taming was greater than this. However, other than having to remember the information about various kinds of beasts by heart, one also had to study different categories of agreements.
