Soldiers, at the end of the day, are violent enforcers, the basic cells of war.
Discard those laudatory adjectives and prefixes, professional soldiers are simply obedient killing machines, the basic components of war.
"Without personal desire, killing a fellow being for an external goal, proving oneself to have the awakening of killing and the potential to become a violent tool. This is the basic ritual of the war god 'Lover of Chess'? Then, if you intentionally kill someone because of a certain emotion, like hatred or possessiveness, it won't work?"
"That is the ritual of G.T (Brother Tu), the god of slaughter and butchery. The first-tier path is Butcher. These two are mortal enemies... well, Brother Tu has many enemies, Lin Nu, FON, and most of the war gods, all want to kill him."
Soldier and Butcher, these two pathways were not introduced in that "Five Three" book.
