So from what i read later on this was kind of the whole point it was to trick them and the audience.this defeat does make some sense..
Only option left was to use sword/knight techniques in a normal(?) body.. I wish the dual lasted a bit longer while she uses a limited but advanced subset of techniques.
- Sealed vampire abilities
- Purple sword spirit is resting
- Racist sword is sleeping
- Sword Saint abilities not awakened
I get the author wanted her to struggle with strength for a bit but such a short dual is hard to feel the struggle.
So from what i read later on this was kind of the whole point it was to trick them and the audience.
her vampire ability's were never sealed they were just hiding to get Mc close to the Empress, The mc has been trying to save his sisters soul this whole time counting that the Empress's souls basically dominated the sisters soul, much more shenanigans happens,
Mc's Soul gets sealed up and replaced with the "Knights" soul (this is just a ruse) and the Empress starts to trust them ALOT.
