"Dad i been thinking can i join the hunter exam when i turn 10 years old" Frost said
"why do you want to do that dear, the hunter exam is pretty dangerous you know. Even though you mastered the basic and advance application of nen there might be some people who are joining and know nen as well." Ash said bewildered
"i just want to go outside world and have my own adventure, while fighting strong opponent so i can improve faster." Frost replied
"ok you can go to the exam on the condition that you have at least master a hatsu ability before you turn 10." Ash replied
"yay thank you" Frost yelled in joy
"Ok lets continue, Now as you recall Nen is divided into six types, because you have 100% proficiency in all six types we are going to work on all of it. Since you were naturally strong we will have to increase your weight and physical training again as well." Ash said as he hand over a book that contain all the exercises you need to complete before you consider a master at the particular nen type.
two years has passed since then. During these two years of practice he have manage to fully master three types of nen, they are enhancer, transmuter and conjuration. For the other three types of nen he was only able to become around 30% proficient in two of them, while with manipulator he managed to became 50% proficiency with it. Because of his diligent practice of physical exercise with a total carry of 100 kg and the cultivation technique he has managed to increase the strength of his physical body, making it a little bit stronger than Ubo of the phantom troop and he also has a lot more nen than most hunters.
During these 2 years he hasn't really focus much on hatsu ability so right now he is meditating in the back yard trying to figure out what type ability he would want to create, he want an ability that can incorporate all the nen type together like Netero to create a unique fighting style. Suddenly i have an idea i can use ultimate blade work and Gate of Babylon as the base for my fighting style, while i will use conjuration combine transmutation to create special swords. To further strengthen my abilities i can put some conditions and restrictions on the abilities, Even though it's already going to be strengthen because of the abundant nen i am going supply it while fighting. During my past life my other favorite anime was fate/ stay knight, so i will use the ability of my favorite character as the base for ability while i will create more ability to further compliment it.
