16 Marine Six Powers

Jack wanted to learn all six powers because he can use them anytime if he cannot use devil fruit powers.

He also want to combine those with his devil fruit. So he started training. The easiest one was kami-e. Its about making your body into paper and go along with attacks.

Its like breathing technique which first focus on brain rather than body. Since , Jack is clam and collected behind his cheerful facade he is able to grasp the basic of it with in a month.

Next comes soru then geppo , these are opposite to kami-e which focus on mind. Soru is kicking the ground atleast 10 times. Geppo is on air, but one needs to master soru to use geppo.

Since its about controlling once power and using it for 10 times , Jack was able to master soru in no time. Even he is able to use geppo for 10 times after 2 months.

As Jack was only using legs for two months to learn them. His legs are more stronger than torso. So, he practised Rankyaku, slicing winds using legs. He is able to perform it one out of five tries.

He started learning tekkai then after. Its like making your muscle stiff just like showing your muscle in Mr. Olympia. It is most difficult technique among the six.

One need to get smashed with iron throughout his body if they want to master this. Jack felt like he is participating in Mr.Olympia rather than training Tekkai.

Shigan is using tekkai at end of your finger. Along with that he need to thrust his finger like a spear and have control over strength. He took four months use the three.

Z first was surprised to that he was able to do Kami-e with in month. He got shocked to hear about mastery over next two techniques. He praised Jack for a while to keep doing it. As he heard him about mastery over next one , Z was calm.

Many others admired him and started to train in it. Even other ask him pointers including Ain, Binz as Leo started it. Smoker and Hina also focused on physical strength for their last year of training.

Jack now has 5 months before he can start missions. So, now his main focus was increase the potency of them. There is a measuring device which tell him about his mastery. At first it was 600, it increased 3 times for the past 5 months.

There are some device to increase the level. For kami-e there will be different types of objects thrown towards him inside a room. The level increases as he dodge.

For shigan and Rankyaku there are stones placed. He need to pierce them with fingers or use Rankyaku to cut them. As for soru , geppo and takkai he need to use repeatedly.

All the higher ups got about his mastery over Rokushiki. Akainu called him to complement his efforts as he was the one to allowed him to join marines.

Jack got furious seeing Akainu. Where were you these past 2 years , you are nothing but a hypocrite ; you just want to tell others about it , Jack want to shout these words but kept silent.

Sengoku called him too. He arrived after meeting Akainu. " You are talented to master them with in a year. Keep the effort ", Sengoku praised him. Garp laughed , " Hey, brat want to spar with me ", he show his fist.

" No , Sir. You are flattering me ", Jack denied it. " What do think about Justice ? ", Sengoku got serious. Here it comes, Jack thought.

" I am not strong enough to think about it, Sir ", Jack. Garp laughed hearing that. Sengoku frowned, " Good escape. But I want your opinion ". He is not like Akainu at all, Jack admiration on Sengoku increased.

" Maintaining the order, Sir ", Sengoku indicates him to continue. " Protecting civilians from danger ; capturing pirates or underworld, if they harm them or killing them".

" You can go ", Jack leaves. " He is clever ", Tsura tell about Jack when only Sengoku and Garp are present. Sengoku sighs as garp stay silent.

Since then Jack is known as monster rookie by others. Some thinks that he can be future admiral learning about his talent and devil fruit powers.

Now 1 year is over since jack started training. Now he can go for missions to hone his skills in combat.
