After figuring out about the Sword Wisdom, Cyrus completely understood why the system has Eve the same sword technique as him.
Not only she can understand and perform that sword technique to perfection proficiency, but she can also help him achieve the same proficiency as long as he diligently follows her instruction.
But it was far easier said than achieving the Perfection Proficiency of a weapon technique.
Because first, Weapon Techniques were also known as Weaponry Spells when they were used with Qi or Magic.
Second, to learn and perform these spells, a weapon related to the spell was required. Third, there are four common levels of proficiency in any Weaponry Spell.
Each level of proficiency represents a certain level of control over the weapon, technique fluency, and an increase in destructive power in the weaponry spells.
Weapon Control was directly related to someone's control over a certain weapon and the most basic requirement to use any weapon.
