Nicole's abilities were something Han Dong had learned about in advance.
In addition to her eight-claw attack ability, Nicole also excelled at deep-sea magic... a rare kind of magic similar to the Yellow Sand Secret Method, which was further strengthened by her deep-sea royal bloodline.
However,
this kind of deep-sea spell generally lacks offensive power, focusing mainly on 'healing' and 'trapping'.
The 'Deep Sea Prison' is the strongest binding spell Nicole currently has at her disposal.
Before the war started, Han Dong personally tested its effects.
Being overwhelmed by seawater, Han Dong wasn't just physically immobilized... more importantly, there was a strange feeling of his consciousness being dragged into the deep sea.
If Han Dong's determination was not strong enough, he might completely immerse himself in it and be unable to extract himself.
