First Gate!

Days passed by one by one,

Twenty days passed since the announcement; At first, many marine recruits are very active and spirited, training on their own to improve their strength.

Then, gradually everyone began to lose their perseverance and quit their training, believing, they are skilled, and sufficient for them to rank in the top 300.

But Rey and Mia trained daily surpassing their physical limit; So, their strength also improved.

Like every day, Rey was training with absolute determination to open his first gate. Lately, the door of his first gate loosened and he is just a step away from opening it.

In the highest of the Marineford Tower, three-figures were seen standing, watching the training ground. They are none other than Garp, Z, and current Fleet Admiral Sengoku.

"This batch of recruits are a bunch of wastes apart from some who are diligent and hard-working, especially, that kid who's exercising daily to surpass his own physical limits", Z said.

"Bwahahahaha, I like that kid, but I don't know what his justice means? Z, What's his name?" Garp laughed and said while eating his rice crackers.

"Be quiet, Garp", Sengoku yelled.

"The world becomes more chaotic in recent years, many powerful pirates began to appear on the Grand Line and four seas. Our Navy's strength needs to be improved if we want to confront every single pirate on the sea."

"Lately, our strength started to decline and many ranks become unoccupied. We need elite marines who are brave and courageous to fill our ranks and overall strength."

"What are you saying? Didn't you recently promote the three brats to Admiral position so that you can relax? Bwahahahaha" Garp cackled with a smirk on his face.

"Shut up, Garp."

"Z, you train them well. Your new arm will be developed soon so you don't have to always worry about it." Sengoku spoke, sighing. He knows Z from his youth and they were also from the same era so whenever he saw his friend without the arm, it makes him frustrated.

Rey who was training his body suddenly heard a noise as if something inside his body has been shattered.

He was shocked and soon excited by discovering that his first gate is finally opened and from his first gate, powerful energy burst forth.

Rey felt powerful and vigorous energy is gushing through his entire body, nourishing his muscles, blood, bones and even every cell; An invisible process took place in his body, improving his constitution.

The feeling was akin to returning to his mother's embrace. Rey clenched his fist and sensed the warm energy was circulating, again and again, flowing into the depths of his body and transforming his Physique.

After what seemed like fifteen minutes, the process stopped. Rey felt he was completely reborn while his body becomes powerful, tough and was beaming with powerful vitality.

Unlike the Eight Inner Gates, the Nine Heavenly Gates Technique is little different; Once the gate inside his body is opened, they are permanent and risk-free.

Even though the strength of opening each gate is not as strong as the Eight Inner Gates, it grants him permanent strength without the need for him to open it every time.

Rey clenched his fist and punched the empty air as he felt his whole body is filled with power and strength.

'Boom' A loud noise echoed as if the surrounding air got exploded.

Rey sensed his strength is now eligible to fight some strong pirates who have a bounty of 5 to 10 million berries.

Unlike before, his Nine heavenly Gates breathing technique was circulating on its own, absorbing the surrounding energy, and constantly improving his strength.

Furthermore, inside his body was pure chakra like energy ready for him use, but Rey doesn't know any techniques or ways to utilize this energy.

Rey knows the pure energy inside him is not chakra since Chakra was basically originated from God Trees and since Kaguya Ōtsutsuki ate the fruit the God Tree bore, she became the first person in Naruto world to wield chakra.

Hence, the pure energy inside him is superior to chakra, so he should be able to do everything the shinobi of the naruto world can do using his pure energy, maybe even more.

First and foremost, he should learn to control and manipulate the pure energy inside his body according to his will.

From that day, Rey began his training on controlling his pure energy while trying different techniques. Like tree climbing, and water surface walking as this are the basic ways he could think of.

Days passed like clouds, the day of assessment drawn near, with only two days left; One could feel the tension among the Marine recruits.

In the training ground, two figures could be seen fighting hand to hand; They are none other than Rey and Mia who are sparing with each other.

Soon, Mia retreated from the fight, gasping for air. "Rey, how did you become so strong within a few days?"

"It's a secret,"

Mia puffed her cheeks in an annoyed manner, "Say, do you think we will be able to clear the assessment and make it to the next round."

"Yes, don't think of yourself as weak; you are stronger than you think," Rey said.

"Really?"

"Of course that's only if you are able to land a hit on me within 10 minutes"

Rey and Mia once again started to train their combat techniques, polishing their skills and techniques. Like them, there are some similar peoples who are practicing and training unlike some who were slacking off.
