(Author's note - Only one more chapter for his training. Even I was feeling irritated when I had to write this chapter. I had to write to develop his ability since he had to face a lot of challenges in Death Abyss.)
Kai decided to create an attack method from the Will Manifestation ability. His attack method was the major weakness he has now; he only has one attack method, and that is [Absolute] but it was a final move and cannot be used regularly in the battle.
He plans to create objects using Will Manifestation and attack them in case his weapon breaks, just like with the one-horned rabbit.
For long-range attacks, he plants to control the object using his Will Power like telekinesis. It will make his battle style more versatile.
There is also a movement technique that he plans to create.
Kai started making objects using his Will Power, it wasn't hard since the application is the same as Will Shield.
