Revealing Marine 's Strength to Luffy

Hearing his words, Nami suspiciously stared at him and asked.

"Can't I explain her Marine Six Styles and Haki while explaining it to Robin?"

She was a bit jealous when she thought about Zack spending time with Vivi alone.

Vivi lowered her head and blushed while Robin simply chuckled.

"Zack, you bastard! What do you plan to do with Miss Vivi?" Sanji burst into flames as he rushed in front of Zack and grabbed his collars.

Zack simply smacked his head and looked at Nami with a speechless expression.

"You think too much. Unlike her, Vivi doesn't have a lot of stamina. So, I plan to give her heavy weights in order to increase her stamina. Devil Fruit, especially Logia or paramecia consumes a lot of stamina."

"More importantly, Miss Archaeologist already has the basic fighting powers. But Vivi doesn't even have that."

Hearing his words, Nami gave him a threatening look saying.

"If you dare to mess around."

She clenched her fist signaling what she would do. She was a bit scared not because she didn't have confidence in Zack but because she didn't have confidence in Vivi.

After all, Vivi did try to steal Zack despite knowing that she loves him.

She didn't want to share Zack with anyone.

As for her words, everybody simply ignored them and walked out of the cabin. Because Merry was quite small, they had to train separately without making much disturbance.

While they went out, Nami saw a news bird on the top of Merry's head. She quickly rushed toward it and paid the money to buy the newspaper.

As soon as she turned around, several bounty posters fell on the ground. Her eyes fell on it and the next moment, she screamed.

"Ahhhhh"

"Nami, what happened?"

Zack quickly rushed toward her but when he saw nothing happening to Nami, he was a bit confused. Then, his eyes shifted toward the posters on the ground.

"Are those our bounty posters? Everyone, our bounty posters have arrived."

Zack walked closer while asking. His eyes fell on the top and when he saw Luffys' smiling and stupid face, he quickly understood the situation.

....

[MONKEY D LUFFY!

Dead or Alive!

B390,000,000]

.....

No wonder Nami screamed like that. It seems like Luffy's bounty shocked her. Although he had already said that Luffy's voice might surpass two Hundred Million Bailey, even he didn't expect it to reach Three Hundred and Ninety Million Bailey.

"Hahaha! My bounty." Luffy rushed in front of Zack and quickly held his bounty poster.

"Three Hundred and Ninety Million Bailey. It seems like Luffy truly threatened Navy. They might send a lot of forces to take us down." Sanji walked near him calmly and expressed his thoughts.

But, he was quickly trying to find his own bounty poster. Unfortunately, the second bounty poster was Zack's bounty poster.

...

[ZACK !

Dead or Alive!

B340,000,000]

....

After that, it was Zoro's bounty poster.

.....

[RORONOA ZORO!

Dead or Alive!

B320,000,000]

.....

Finally, it was his bounty poster.

....

[SANJI!

Dead or Alive!

B310,000,000]

...

"Classic! Zack, you are truly my benefactor." Looking at his handsome picture in the bounty poster, Sanji immediately showed his gratitude to Zack.

"Is that mine?" Nami screamed once again when she saw the bounty poster beneath Sanji's.

...

[NAMI!

Dead or Alive!

B240,000,000]

...

"Wow! I also have a bounty poster." Usopp proudly picked up his bounty poster.

"Mine! Where is mine?" Chopper tried to find his bounty poster but surprisingly his bounty poster had changed a bit.

It was a small piece of paper with a drawing of a Tanuki with the bounty on the last.

...

[CHOPPER!

Dead or Alive!

B140,000,000]

....

[USOPP!

Dead or Alive!

B140,000,000]

....

"I am a reindeer, not a Tanuki." Chopper screamed and tore his Bounty Paper.

"Why does Chopper has the bounty paper like this?" Usopp curiously looked at Zack and asked.

Zack was also speechless. To prevent any missteps, Zack even sent all of those pictures and even information about his crew. Despite that, it seems like there was a misprint.

"It seems like their printing machine got broken before they could publish Chopper's bounty poster." It was the only explanation Zack could give them.

Hearing his words, Chopper who was angered by his nickname fell into depression.

"Anyway, it seems like all of us have the bounty now." Zoro took a deep breath and stared at his bounty poster.

320 million wasn't a low amount. He was a bit excited but also worried. He was afraid that their crew's strength might not be enough to face the future threat.

Zack looked at his expression and immediately understood his mind. He nodded his head and spoke.

"That's why we must train hard. Zoro and Sanji, you two must learn Observation Haki and Armament Haki as soon as possible. Luffy, you already have grasped Armament Haki."

"And, but your Observation Haki seemed quite lacking compared to your Armament Haki. You will train with Usopp for the next days, completely focusing on Observation Haki alone."

"Once we land on the island, you and I will battle each other. Since I have almost recovered, I should be able to squeeze out my Armament Haki. As for my Observation Haki, I should be able to manifest it soon enough."

"We will also train our Conqueror Haki. After all, if we use it unconsciously in battle, it will not only affect our enemy but also our partners. Besides, if five of us manage to control our Conqueror Haki, we can even suppress hundreds of thousands of soldiers at once."

Hearing his words, Luffy, Zoro, Ussop and Sanji simultaneously nodded their heads. They also do not want to affect their partners during the battle.

"Wait, doesn't that mean we can simply suppress our enemy number with Conqueror Haki alone?" Nami suddenly spoke.

Her words brought a questioning gaze to everyone's face. They all stared at Zack begging for an explanation.

Zack chuckled and shook his head.

"You have to understand that our Conqueror Haki might be strong enough to knock out the entire city but they are not proper soldiers. They are nothing compared to elites of the pirate group of navy."

"Currently, there are five known people with strong Conqueror Haki. First, four would be Four Emperors and the fifth one is Fleet Admiral Sengoku and maybe Vice Admiral Garp. Among them, there is still a huge distinction in the strength of their Conqueror Haki."

"Wait, Fleet Admiral and vice admiral garp also has Conqueror Haki?" Robin suddenly interrupted him and asked.

"Isn't it something that only Pirates should possess?"

Zack shook his head and said.

"It is said that during the time when Sengoku was just an Admiral, he used to chase Whitebeard while Garp used to chase Roger Pirates. You should know that Whitebeard at that time was in his prime and possess a similar strength to that of Roger and Garp."

"To fight such people on different occasions alone tells us the strength of Sengoku. But to reach such a level of strength, you must have one of two things. Either you must have practiced one of three forms of Haki to an extreme level or possess Advance Conqueror."

"Although I am not hundred percent sure, it is said that Vice Admiral Garp possesses the strongest Armament Haki possibly conqueror haki too. He used to shatter the mountains with his punch just to train his Armament Haki."

"So, for Sengoku to match Whitebeard, he must practice Advance Conqueror because it was true that he doesn't have such a powerful Armament Haki."

Hearing his words, everyone understood. Except for Robin and Vivi, everyone turned their eyes at Luffy with their jaws dropping to the ground.

"Luffy, your grandpa is too strong."

Their words startled Vivi and Robin who had just joined the crew. Vivi didn't react quickly but Robin was fast enough to react.

"Wait, Captain, your grandfather is Vice Admiral Garp?"

At this moment, she was truly shocked.

Garp wasn't just a name for most people. He was a spiritual belief for common people around the world. Even though she no longer believes in the Marines, she still respects Garp.

"Uh" Luffy didn't think too much. He simply nodded his head. But a few seconds later, his jaw also dropped to the ground.

"What? Grandpa is so strong?"

"Idiot, that's your grandpa ofcourse he is strong." Everyone smacked his head and shouted.

Zack speechlessly looked at his captain and said.

"You truly are an idiot, aren't you? If it wasn't for the fact that his action might break the balance of the world, your grandpa would've entered the Second Half of the Grandline and destroyed the Red Hair Pirates."

Hearing his words, Luffy instantly panicked. He instantly grabbed Zack's collar and asked.

"Wait, are you saying that grandpa fought Shanks?"

Zack pushed him and shook his head.

"No! But, he could do that. Of course, now he might not be able to do that but if it was before, he had the power to do so. In their prime, your grandfather was absurdly powerful."

"Although he didn't teach you Marine Six Styles out of his responsibility as a marine, he did install Life Return into your body."

"What's that?" Everyone looked at him and asked.

"It's the power that allows Luffy to recover just after eating meat. Anyway, we are getting distracted from our main point."

Zack rolled his eyes and continued.

"As I said before, Conqueror Haki depends on the person. Some have strong conqueror Haki while some have weak. And, it can only be developed through battles. Of course, talent is also an important part of it."

"Among four emperors, Whitebeard used to have one of the strongest Conqueror Haki but even his conqueror Haki can't be compared to Shanks' Conqueror Haki."

"Currently, his body doesn't allow him to use Conqueror casually. And, their Conqueror Haki can barely affect Rear Admiral. Of course, it should be able to knock out Captain but it will only weaken Commodore ranking marine to a certain extent."

"But on the other hand, Shank can easily knock out Rear Admiral with his Conqueror alone and he can even bring Vice Admiral to his knees with his Conqueror alone."

"Even if five of us combine our Conqueror Haki, it can't match his Conqueror. Each emperor has the power to fight against the whole navy."

"And, if you want to fight someone like Red Hair Pirates, you not only need all of the marines but also Shichibukai, and even then, there is a chance that Red Hair Pirates might win basically because their aren't any devil fruit users in the crew. You all can understand what level of haki they must possess to be a Yonko crew."

"Of course, other pirate crews aren't the same. And, that's only because the right-hand man or deputy captain of Red Hair Pirate has the power to fight against Shanks. He might die in life and death battle but he won't lose."

"That's why if we want to surpass them, we must have similar strengths."

Hearing his words, Luffy clenched his fist and spoke.

"We will surpass them. I promise Shanks that I will gather a crew that will one day surpass his crew and becomes King of Pirates before returning this hat to him."

Saying so, he slowly smiles showing his white teeth.

"Now, I am already close to that goal. We just need to recruit a musician."

As soon as he said that, everyone kicked him except for Robin and Vivi.

"Idiot, we need Shipwright before that."

Zack speechlessly shook his head. Because of Uta, Luffy's head has filled with musicians.

"Alright, that's enough for today."

Zack stood up and walked out of the cabin. Although he hadn't completely recovered, he had something in his mind. He also pulled Usopp while walking out of the Cabin.

After that, he sat on the ground and took out a paper and pencil. He started drawing a picture.

It was a weapon. Its shape was similar to that of an axe but it was a bit different. It had a long staff in the middle with one of its edges made out into a sharp semi-circular edge and the other edge into a flat hammer-shaped.

And, on top of it, there was a line coming out. It was simply the extension of the staff but with a sharp tip.

"Alright, help me make this weapon. I don't have a lot of requirements. Just use heavy iron for this staff and use sea-stone power on each edge of this weapon including the tip."

Hearing his words, Usopp speechlessly stared at him and said.

"Just this design is complex enough, now you want to make it heavy and also use sea stone?"

Zack rolled his eyes and said.

"Although I love using my fist, I found that relying on the weapon isn't a bad idea. But, I also use different kinds of weapons. So, I thought of this design since it not only has the function of a hammer but also can be used like a spear and sword/axe."

Usopp heavily sighed and nodded his head. After that, he started working on it while Zack simply started stretching his body. Because he hadn't completely recovered, he was planning on doing some normal training.

"Hey Nami, how long will it take us to reach the next island?" Zack turned around and shouted.

"Maybe one or two days." Nami who had just come out of the cabin answered.

"Good!" Zack nodded his head and continued training. Since it would take more than one day, his body would recover completely. After stretching his body for a while, he called out to Vivi.

"Next, let's start your training. Before I give you the devil fruit, you need to properly train your body so that you can easily use your devil fruit abilities. Remember, devil fruit is just an extension of your power. Your core strength remains your body."

Zack started guiding Vivi to which she listened very carefully. In the middle, Robin also barged in. She said that it would be a lot easier if he explains everything to her as well.

Thinking about it, Zack also nodded his head.

"First, let's start with three basic training schedules. Number one would be basic training such as push-ups, pull-ups, weight lifting, and so on. You can find Zoro who always trains with these and ask him for a clear training method."

"Also, while doing all these, you need to wear some weights. You start from the lower end but eventually, you need to wear heavier weights in order to make your training much more fruitful."

"Although your progress might not be as fast as mine, do keep in mind that if you over do it then you will suffer tremendous consequences. Vivi is already aware of this. So, I am just reminding you."

When he said that, he stared at Robin. She simply nodded her head. Although she hadn't trained for a long, she didn't mind joining this kind of training.

"Number two would be swimming/sea-stone training. From today, Vivi will be tied with a small rope and she would need to swim in this sea for at least two hours each day."

"As for Robin, you need to start with your sea-stone training. Usopp will handcuff you with the sea stone handcuffs. And, if you don't feel good about handcuffs, then you can ask him for another item that will stick to your body unless you physically want to remove it."

"This training is really important since it gives you the power to fight even with sea stone handcuffs or even if you fall into the sea. Remember, just because you fall into the sea doesn't mean you can't use your devil fruit powers."

"It's just that you feel too weak to use your devil fruit powers. This is essential for your future training."

After explaining, he looked at both of them for a moment. Seeing that both of them had no disagreement about this training, he moved on to the third part of the training.

"Finally, the Number three would be Marine Basic and advance Six Styles. Whether it is Vice admirals, or Rear Admirals, or even Admirals, everyone from Marines trains these six styles to the core."

"Although all of them might not be suitable for everyone especially those with devil fruit abilities, you can still learn all of them and try to incorporate them with your devil fruit."

"For example, if I remember correctly, your Flower-Flower Fruit allows you to create another arm, right? If you manage to train Finger Pistol and merge it with your devil fruit ability, you can seriously injure higher-level marines or pirates with ease."

"And, if you learn Armament Haki, it would be even deadlier. The same thing applies to Vivi's future devil fruit. If she learns Paper Arts, she will be able to better utilize her devil fruit ability to turn into the sand or any other suitable devil fruit."

"After all, in the future, we will find a lot of people who will know Armament Haki. And, from Paper Arts, you will be able to develop Observation Haki as well."

"Same goes for Iron Body. It will help you awaken Armament Haki though it will take you a while to do so."

Hearing his words, Robin and Vivi nodded their heads together. Vivi thought for a moment and asked.

"Zack, when should I eat a devil fruit exactly?"

"When you can master two of Six Marine Styles. It doesn't matter which one. As long as you can master two of them." Zack answered.

Vivi clenched her fist and nodded her head. She also wanted to train more now. Without a lot of training, she wouldn't even get a chance to eat the devil fruit.

On the other hand, Robin looked at Zack with a smile and asked.

"Vice-Captain, do you think I should start my training now?"

Zack rolled his eyes and said.

"Of course! Let's start training right now."

Saying so, he started doing some push-ups. Robin saw that and also started doing some push-ups alongside Vivi.
