One Piece: The greatest swordsman of the Rocks era!

"Ordinary blades will inevitably have gaps in collisions, and may even be cut off by a sharper knife."

Golden Lion Shiki's expression became solemn, and then he said: "The black knife uses the Armament Haki to temper the knife, making it sharper and tougher."

"As long as your Haki is strong enough, your knife will never be damaged!"

"Even after hundreds of years, it can still cut iron like mud!"

"This is the black knife!!"

In the final analysis, the power of the black knife depends on the power of the user's Armament Haki!

Said.

Golden Lion Shiki pulled out the long knife from his waist, and his arm suddenly turned into black metal, reflecting bursts of cold light.

And the Armament Haki quickly spread from his arm to the originally bright blade.

It also made the blade quickly turn black.

The golden lion Shiki, holding a cigar in his mouth, said very complacently: "This is the black sword!"

"Huh~"

He turned his head and spit out a puff of white smoke.

Seeing this, Ares' eyes were shining with golden light, and his heart became excited, "With Armament Haki, my body can become harder than a sword!"

"As long as my Armament Haki is strong enough, I can surpass those famous swords!"

"No!"

"Not only a famous sword, but the supreme big sword Twelve Works!"

He looked excited and excited, and his eyes as big as car lights stared at the golden lion, and he said anxiously: "Quick! Teach me Armament Haki!"

The three of them had unknowingly walked to the front of the Skeleton Castle.

Whitebeard smiled and said: "Let's go in first. With your physical fitness, you can learn Armament Haki very quickly!"

Just entered the Skeleton Castle.

Whitebeard and the golden lion quarreled again, both asking to go to their own rooms.

Whitebeard said angrily: "Yellow-haired lion, your room is so broken, you still use it to entertain Ares?!"

Golden lion retorted: "My room is broken, why don't you go to my subordinate's room?"

"Ares is learning Armament Haki from me, why are you, white-haired bearded, joining in the fun!"

"·········"

"You can teach Ares Haki, but I can't teach him?"

"White-haired bearded! Do you know how to temper a black knife?"

"······"

The two of them couldn't agree.

Face to face again, if Golden Lion hadn't had a cigar in his mouth, Whitebeard's face might have hit Golden Lion's face.

"Okay, let's go to my room!"

Ares stopped the "living enemies" and made his own suggestion.

Whitebeard and Golden Lion looked at Ares at the same time, their faces separated, and they stood on the left and right sides of Ares.

Both agreed to this proposal.

After solving this problem, the three of them went to Ares' room with their arms around each other.

The other pirates who saw this scene were all stunned.

There were only the simplest furniture in the room, and Whitebeard and Golden Lion didn't care. Anyway, their target was "Ares".

Golden Lion glared at Whitebeard fiercely and said to Ares: "This Armament Haki is the Qi in the body!"

"To practice Armament Haki, you must have a perfect control over your body!"

"The power and potential of the human body can be stimulated!"

His eyes were filled with strong expectations. What level of "Armament Haki" can a monster like Ares reach in the future?

He said again with some excitement: "Ares, put your hand on my arm and feel how I, Golden Lion, use Armament Haki!"

Hearing this.

Ares also excitedly put his big hand on Golden Lion's arm and said: "Okay, let me see Armament Haki."

The next second.

Buzz!

With a trembling sound, the arm of the golden lion instantly hardened with Armament Haki, just like polished black metal.

"Awesome!"

Ares couldn't help but shout excitedly, his big copper bell eyes sparkling, exclaiming: "This is Armament Haki, it can make the body harder than metal!"

"So hard!!"

"This is what I want!!"

His heart instantly began to beat violently, and he saw the hope that his body could surpass the unparalleled great sword Twelve Works.

With Armament Haki, his body must be harder than those famous swords! !

Seeing Ares's excited expression, the golden lion raised his mouth and said proudly: "How is it, hard enough?"

He suddenly recalled the happy time last night and the loud and clear "singing" of MISS. Ba Jin last night.Armament Haki is really hard and strong, and it's really useful!

The Golden Lion quickly restrained the spring light in his mind and continued: "No ordinary attack can break through the defense of my Armament Haki."

"Ares, Armament Haki is a skill that must be practiced on the road to becoming a strong man!"

"It can stimulate your strength exponentially!"

The Whitebeard on the side also grinned and said: "Kulalala... Shiki is right. If you want to become the top strong man in this sea, you must have a strong-Armament Haki!!"

Their loud words fell into Ares' ears, and the blood in his body began to boil involuntarily.

He also recalled the strange feeling when he touched the Golden Lion's arm just now.

The human body can continue to become stronger through exercise.

The blows and collisions made Ares's skin, muscles, and bones harder and more durable, but compared with the changes in the Armament Haki of the Golden Lion.

The difference is obvious!

Ares is convinced that Armament Haki is the "hardness" he has always pursued!

And it is a powerful ability that is enough to make his body harder than the Supreme Big Blade Twelve Works.

He began to recall the scene of Golden Lion Shiki using Armament Haki, and the scene played in his mind like a slow motion.

Normally, a person's memory will only be remembered if there is a "deep" impression, and most of it will be "forgotten".

Unless it is repeatedly trained and deliberately strengthened, it will be forgotten and disappear.

Only then there is the saying "A good memory is not as good as a bad pen"!

But Ares is different, as long as he wants.

Everything that happened can be replayed in his mind, and it can be accelerated or slowed down according to his thoughts and will.

All because of a certain day a few years ago.

Since that day, his soul brain seems to have become extremely "special"!

Now.

Ares replayed the feelings and scenes of Golden Lion using Armament Haki in his mind over and over again.

Falling into deep thinking and memories.

Golden Lion looked at Ares in surprise, and said to himself: "This guy seems to be thinking about how to use Armament Haki, but Armament Haki can't be learned in one or two days."

Then he chuckled: "It took me more than a month to use Armament Haki skillfully."

"More than a month, then I am much faster than you, it only took me more than 20 days!" Whitebeard raised his chin proudly, and the sound he made blew the beard on his mouth.

Quite interesting.

Golden Lion looked at Whitebeard with a rather unhappy expression, and responded with a proud face: "That's because your physical skills are strong, and I, Golden Lion..."

"It's the double-sword style-the great swordsman!!!"

Just at this moment.

A voice broke the argument between the two.

"This..."

"It's Armament Haki, right?"
