In the Navy: Inventing Enhancement Stones at the Start (Author: Beard White)

Summary:

[Navy + Invention + Thrilling Novel] Hill transmigrates into the body of a scientist in the Navy's scientific research unit. Activating the item supply system, he immediately generates [Enhancement Stones], drawing Golden Light Mantra, Hundred-Step Flying Sword, Gourmet Cells, Three-Colored Haki, and more from the system to enhance himself.

He was not only hailed as a "genius scientist" but also as "the most powerful admiral in the navy in hundreds of years".

Aokiji: "Oh my... can this enhancement stone enhance my eye mask and bicycle?"

Subsequently, the eye patch was upgraded to +12!

Bicycle upgrade +12!

In an instant, the navy was swept up in a wave of strengthening!

It even drove the whole world crazy.

Akainu: "Kaido, aren't you supposed to be the strongest creature? Today I'll let you experience the power of my +12 enhanced gauntlets!"

Kizaru: "Strength is power. Have you ever been cut by a +12 Ama-no-Murakumo-no-Tsurugi?"

In addition to enhancement stones, the item supply system also offers all sorts of other strange and wonderful items!

And the war that gathers countless powerful figures has begun!

"I, Admiral Hill, will not allow anyone to rescue Ace today!"

Chapter 1: Kizaru Forced to Work Overtime

Naval Headquarters.

Marineford.

The weather was fine and sunny.

Warm, soft rays of sunlight streamed through the window.

It poured freely into the room.

Admiral Kizaru leisurely picked up the teapot and poured tea into a cup.

The boiling water caused the tea leaves in the teacup to swirl and tumble.

"Looks like another uneventful day. Three more hours until I get off work. This pot of tea will be just right." Kizaru squinted slightly.

His face was filled with a look of enjoyment and contentment.

Leaning back in the chair, with both feet on the desk.

He picked up his teacup and leisurely blew on it.

Knock knock knock!!

There was a series of urgent knocks on the door.

"Old man!"

"Grandpa! Open the door quickly!!"

Outside.

Sentomaru from the Science Unit pounded on the door.

The sturdy door panel trembled as he pounded on it.

Sentomaru's face showed excitement.

Her eyes sparkled.

In the office.

Kizaru's expression changed.

"Does this mean I have another mission?"

He pursed his lips, revealing a somewhat helpless expression.

After pursing his lips and taking two sips of tea, he reluctantly put the cup down.

"What a pity... my fine tea."

Pull your legs back up from the table.

Walk to the office door and open it.

Behind his sunglasses, a hint of annoyance flickered in his lecherous eyes. "Senmonomaru, what's up?"

I had already begun to pray in my heart.

Please make sure it's not a dangerous mission.

Sentomaru's face beamed with excitement, and he shouted excitedly, "Grandpa, this is great news!"

"What a wonderful thing!"

Good news?

Kizaru's expression froze for a moment, then he asked with a hint of surprise, "Could it be that Fleet Admiral Sengoku has agreed to give me a raise?"

"So you've agreed to lighten my workload?"

"no!"

Sentomaru slammed the door shut and excitedly replied, "The Science Unit has a new invention! It's Hill, he invented something new!"

He immediately pulled out his so-called "new invention" from his pocket!

Looking at what Sentomaru was holding.

Admiral Kizaru looked surprised and asked in confusion, "This stone is Hill's new invention?!"

"This stone... what kind of invention is that?!"

In Sentomaru's hands.

A black stone lay quietly in his palm.

This kind of stone?

Can it really be called an invention?

Kizaru immediately lost interest and picked up the teacup on his desk.

He leisurely took a sip.

Sentomaru, however, persisted, quickly saying, "Grandpa, you mustn't underestimate this stone in my hand."

"It's really amazing."

Hill said this stone is called a strengthening stone!

As he spoke, he took the double-edged giant axe off his back.

He asked, "Grandpa, do you see any changes in my axe compared to before?"

Kizaru glanced at it indifferently.

A hint of surprise flickered in his eyes behind the gold sunglasses. "Your axe seems to have become sharper. Could it be because of the stone in your hand?!"

With a touch of seriousness.

He walked up to Sentomaru.

Looking at the axe in Sentomaru's hand.

It is a little different from before, but even if it is a little sharper, it shouldn't make Sentomaru so excited, right?

Sentomaru also provided an answer: "Grandpa, my axe is not just a matter of being a little sharper!"

"This double-edged battle axe of mine is a +1 level weapon, which can amplify my Armament Haki!"

"It was strengthened using the strengthening stone I have."

"I've only used one enhancement stone. If I had more, my weapon would not only be sharper, but it would also amplify my Armament Haki even more!"

"Even more powerful!"

Sentomaru talked incessantly to Admiral Kizaru about the changes to his axe.

It also describes the effects of the strengthening stones.

"Um?!"

Kizaru's lewd face turned serious, somewhat surprised: 'You mean this axe can amplify your Armament Haki?!'

"Impossible?!"

This surprised him somewhat.

The strength of Armament Haki varies greatly from person to person.

I've never heard of anything that can amplify Armament Haki.

The strength of Armament Haki depends entirely on one's own power and mastery of it.

Sentomaru also knew that such a thing was indeed somewhat unbelievable.

He raised the huge axe in his hand, "If you don't believe me, old man, you can try it yourself!"

He took the axe.

Kizaru also wanted to see if this axe could really amplify Armament Haki.

A faint, invisible, and colorless Armament Haki spread from his hand to the axe in his hand.

His face showed surprise.

He noticed that his Armament Haki was gathering on the axe blade.

You've gotten stronger!

Although very faint.

However, Kizaru clearly felt that the weapon did indeed amplify his Armament Haki!
