One Piece: Enhanced Supreme Grade Sword

and...

This is still the reason why he didn't use much Armament Haki.

If the domineering aura increases!

This increase will be even more pronounced.

Kizaru said to himself, "It's increased by about 2%, which isn't too strong, but it's not too weak either."

"For the strong, the amplification effect is quite significant."

"But for the weak... this increase is not enough."

Upon hearing this...

Sentomaru chuckled.

"Grandpa, have you forgotten what I just mentioned about the strengthening stones?!"

As he spoke, he slammed the enhancement stone in his hand onto the axe.

As the reinforcing stone struck the gleaming axe blade...

It burst forth with a powerful light.

It actually merged into the axe in Kizaru's hand.

This sight astonished Kizaru. "The stone has vanished, completely merging into the axe?!"

"Yes!"

Sentomaru responded, "I also found it incredible at the time, but it was Hill who used this stone to change my axe."

"Grandpa, look at the axe now, what's different?"

Kizaru also carefully examined the axe in his hand.

It has become even sharper.

He also tried to use the power of Armament Haki.

His expression changed.

With a look of surprise.

"The amplification has actually increased! It's now around five percent!" she exclaimed.

"This increase is significant; it's enough to influence the outcome of battles between powerful individuals."

"I never expected... these enhancement stones to be so amazing, capable of amplifying the effect of Armament Haki on weapons!"

Five percent.

It doesn't seem like much.

However, each strike is amplified by 5% of Armament Haki.

The combined effect is terrifying!

Kizaru turned to Sentomaru and asked, "Did Sheele invent this magical enhancement stone?!"

"Not bad!"

Sentomaru took his axe back from Kizaru's hand, touching the blade. "Grandpa, this isn't the limit. The main problem is we don't have enough enhancement stones..."

"Otherwise, this axe could amplify Armament Haki even more!"

I felt a surge of joy.

My axe has been upgraded another level!

Kizaru was also shocked. "You mean, with the enhancement stones, this axe can be made even stronger?!"

A five percent increase is already quite alarming.

If only we could increase it even more....

They could completely crush strong opponents of the same level with the power of their weapons.

"Then what are we waiting for?!"

"Let's hurry over to the Science Unit and see that guy Hill!"

"I'd like to see just how much this Armament Haki can amplify!"

Done.

He then walked out of the office.

Headed straight to the location of the science unit laboratory at Naval Headquarters.

Chapter 2 System Bound Person

In the laboratory.

"Phew, we've only made five enhancement stones so far, and Sentomaru used one and took one away." Hill looked at the enhancement stones that had just been completed on the experimental table.

He wiped the sweat from his forehead.

He is not from this world.

He was a time traveler.

A crafting system has been awakened, which can unlock all sorts of items.

The first item he unlocked was: an enhancement stone!

No furnace is needed.

It can be used directly on items.

You can earn points by manufacturing them.

Once you reach the required number of items to craft, you can unlock crafting the next item!

Hill also paid attention to the information existing in his mind.

[Points: 50!]

"Each enhancement stone gave me 10 points, and now I have 50 points."

"It's about time for a prize draw."

There are five levels of treasure chests in my mind.

A bronze treasure chest, opening one requires 1 points.

Silver Treasure Chest: 10 points.

Golden Treasure Chest: 100 million points.

Diamond Chest: 1000 million points.

Seven-Colored Magic Box: 1 million points.

[Open five silver treasure chests!]

The system in my mind also showed me a series of glittering silver boxes.

[Open the Silver Treasure Chest: Obtain the Golden Light Spell!]

Hilton was pleasantly surprised. "Huh?! Holy crap... isn't this the old master's signature move?"

I never expected to participate in a lottery for the first time.

I actually won something this good!

Although it is only an introductory cultivation method of Taoism.

However, if one cultivates to a high level, one may not necessarily be less powerful than the Old Celestial Master.

My heart was filled with joy.

[Open the Silver Treasure Chest: Gain 20 attribute points.]

"good!"

[Open the Silver Treasure Chest: Obtain Zoan-type Cat-Cat Fruit, Tiger Form!]

"what..."

Hill's eyes lit up, quite surprised. "I didn't expect to get a Devil Fruit from the Silver Treasure Chest. What a pleasant surprise!"

"Moreover, the tiger form's abilities seem to be quite good."

"I'll look incredibly majestic when I transform!"

"However, it is still far inferior to the Logia and Mythical Zoan types."

nice one.

Even if I don't use this thing myself.

You can also keep them and sell them. You could get hundreds of millions of Berries and exchange them for points to enter the lottery!

[Open the Silver Treasure Chest: Gain 15 attribute points.]

[Open the Silver Treasure Chest: Obtain one Youth Preservation Pill!]

"Um?!"

The last reward surprised Hill somewhat.

He muttered to himself with a hint of helplessness, "I don't think I need this for the time being!"

He is only twenty years old now.

He's incredibly handsome.

Handsome and dashing.

Handsome and dashing.

"Let's put the Youth Preservation Pill and the Devil Fruit aside for now."

"Claim attribute points and Golden Light Mantra!"
