"Here she comes, this girl is about to try using the Ghost Control skill. How will she do it?"
Truth be told, while powerful, this skill needs to be developed. It's a bit awkward early on, equivalent to having control but no output.
However, An Jianyou's base attributes are still pretty decent.
'An Jianyou'
'Physique: 1.5'
'Spirit: 1.7→1.8→2.0'
'Mystery: 0.19'
'Skill: Ghost Control (Entry Level: 3.1%)'
Her spiritual power is very strong, having reached 2.0. With such a foundation of spiritual power, Fang You believes that even just with control, An Jianyou could wield the Ghost Control with significant force.
The most important thing is that she has a natural talent, and the Passage to the Mystic Eye is not just for seeing.
